Description

微開關電子書寫板與膽固醇液晶模組Micro-switch electronic tablet and cholesterol LCD module

本發明係關於一種微開關電子書寫板與膽固醇液晶模組,特別關於一種可偵測書寫或擦拭位置的微開關電子書寫板與該微開關電子書寫板的膽固醇液晶模組。 The invention relates to a micro-switch electronic writing board and a cholesteric liquid crystal module, in particular to a micro-switch electronic writing board capable of detecting a writing or wiping position and a cholesteric liquid crystal module of the micro-switch electronic writing board.

膽固醇液晶(Cholesteric liquid crystal)是在向列型液晶中加入旋光劑(chiral dopant)使其具有螺旋狀的排列結構,並利用在不同電壓差的情況下呈現反射與穿透兩種不同液晶分子排列狀態來達到不同的光線穿透率,達到顯示效果。其中,在平面態時,入射光會被反射而顯色;而在焦錐態時,入射光大部分穿透、少部分被散射;而在垂直態時,入射光則會完全穿透。 Cholesteric liquid crystal is a chiral dopant added to a nematic liquid crystal to have a helical arrangement structure, and exhibits two different liquid crystal molecules arranged to reflect and penetrate under different voltage differences. The state is to achieve different light transmittance to achieve the display effect. Wherein, in the planar state, the incident light is reflected and developed; in the focal conic state, the incident light is mostly penetrated and a small portion is scattered; and in the vertical state, the incident light is completely penetrated.

由於膽固醇液晶處於平面態及焦錐態時均屬於穩定態,因此當電壓關掉消失時,仍會維持在原來的狀態與顯示畫面,只有在改變成另一種狀態與顯示畫面時,才需施加電壓,這種具低耗電及可記憶性的特性,也使膽固醇液晶成為電子書之首選。同時,這種顯示機制受到上下板間距的影響較小,具有發展成為雙穩態可撓曲式顯示器的潛力及應用。相較於其他型式,例如TN型液晶顯示器來說,膽固醇液晶顯示器具有省電、彩色顯示、可調光及可應用於雙穩態可撓式顯示器等優點,應用上相當廣。 Since the cholesteric liquid crystal is in a stable state in both the planar state and the focal conic state, when the voltage is turned off, the original state and the display screen are maintained, and only when it is changed to another state and display screen, it is required to be applied. Voltage, this low power consumption and memory characteristics, makes cholesterol liquid crystal the first choice for e-books. At the same time, this display mechanism is less affected by the spacing between the upper and lower plates, and has the potential and application to develop into a bistable flexible display. Compared with other types, such as TN type liquid crystal displays, the cholesteric liquid crystal display has the advantages of power saving, color display, dimming, and application to a bistable flexible display, and is widely used.

目前膽固醇液晶書寫板大部分係以物理力按壓來進行轉態。然而這種膽固醇液晶書寫板要偵測書寫位置或進行局部擦拭時,需要額外在其液晶模組的陣列基板上配置對應的位置感測元件。然而,因為要在陣列基板上配置位置感測元件,因此需要進行非常多道的半導體光罩製程。也就是說,目前在具有位置偵測功能的膽固醇液晶書寫板中,其負責位置感測的元件結構相對複 雜,所以製造成本相對地被提高。並且,也會因為所額外增加的半導體製程步驟,導致良率低下。 At present, most of the cholesterol liquid crystal writing boards are physically pressed to perform the transition state. However, when the cholesterol liquid crystal writing board detects the writing position or performs partial wiping, it is necessary to additionally arrange corresponding position sensing elements on the array substrate of the liquid crystal module. However, since the position sensing elements are to be disposed on the array substrate, a very large number of semiconductor mask processes are required. That is to say, in the cholesterol liquid crystal writing board with position detection function, the component structure responsible for position sensing is relatively complex. Miscellaneous, so the manufacturing cost is relatively increased. Also, the yield is low due to the additional semiconductor manufacturing steps.

承上所述,如何提供一種免去半導體製程而使其製造成本下降,且兼具偵測書寫位置或擦拭位置功能的膽固醇液晶書寫板,乃為一重要課題。 In view of the above, how to provide a cholesterol liquid crystal writing board that eliminates the semiconductor process and reduces the manufacturing cost, and has the function of detecting the writing position or the wiping position is an important subject.

再者,若免除半導體製程,則現有的膽固醇液晶模組想要達到偵測書寫位置或擦拭位置的功能即無法達成。因此,如何提供一種既可免除半導體製程且製造成本下降同時兼具有偵測書寫位置或擦拭位置功能的膽固醇液晶模組,亦為另一重要課題。 Furthermore, if the semiconductor process is dispensed with, the function of the existing cholesteric liquid crystal module to detect the writing position or the wiping position cannot be achieved. Therefore, how to provide a cholesteric liquid crystal module that can eliminate the semiconductor process and reduce the manufacturing cost while also detecting the writing position or the wiping position is another important subject.

第三透光基板24具有複數個貫穿第三透光基板24的第二導電孔241,且第三透明電極層25設置於第三透光基板24面向第一膽固醇液晶層23的表面242上,並延設至第二導電孔241內,使得第三透明電極層25可經由第二導電孔241及對應的第一導電孔133而與對應的第一透明電極層14電性連接。因此,各微開關單元10分別與其對應的透明導電層12、第一透明電極層14、第一導電孔133、第二導電孔241及對應的第三透明電極層25對應設置。 The third transparent substrate 24 has a plurality of second conductive holes 241 penetrating through the third transparent substrate 24 , and the third transparent electrode layer 25 is disposed on the surface 242 of the third transparent substrate 24 facing the first cholesteric liquid crystal layer 23 .

In addition, the micro-switch electronic tablet E can further include a sealing layer (not shown), and the sealing layer can be a frame glue, and is disposed between the third transparent substrate 24 and the first substrate 21 to seal the third light transmission. The outer periphery of the substrate 24 and the first substrate 21 has a gap between the third transparent substrate 24 and the first substrate 21. The accommodating space can be formed by the third transparent substrate 24 and the first substrate 21 and the sealing layer, so that the cholesteric liquid crystal molecules can be filled in the accommodating space to form the first cholesteric liquid crystal layer 23. The first cholesteric liquid crystal layer 23 of the present embodiment includes a plurality of liquid crystal control regions 231, and each of the liquid crystal control regions 231 is disposed corresponding to each of the micro-switch units 10. In other words, the range of each liquid crystal control region 231 is defined by each micro-switch unit 10, and the cholesteric liquid crystal molecules of the corresponding liquid crystal control region 231 can be controlled by the micro-switch unit 10. When the voltage signal is transmitted between the third transparent electrode layer 25 and the second transparent electrode layer 22 corresponding to the micro-switch unit 10 and a voltage difference is generated to generate an electric field, the cholesteric liquid crystal molecules of the corresponding liquid crystal control region 231 can be controlled to rotate.

在本實施例中,第一透光基板11為軟性透光基板,且第一透光基板11、第二透光基板13與第三透光基板24分別為可透光基材,但第一基板21為光反射基板或光吸收基板,其會反射或吸收進入的光線。另外,第一透光基板11、第二透光基板13、第三透光基板24、或第一基板21的材料可分別為塑膠或玻璃。當第一透光基板11為玻璃基板時,其厚度可介於0.1毫米與0.35 毫米之間(0.1mm≦d≦0.35mm),使第一透光基板11具有可彎折的特性。具體來說,一般較厚之玻璃基板(例如0.5mm~1.5mm)的硬度較高,難以因按壓而彎折或變形,但第一透光基板11若使用厚度只有0.1毫米與0.35毫米之間的玻璃的話,則可呈現可撓特性而具有可按壓、書寫功能。在一些實施例中,第一透光基板11可例如但不限於利用化學機械平坦化(Chemical Mechanical Planarization,CMP)製程研磨減薄厚度到0.1毫米與0.35毫米之間。在一些實施例中,若第二透光基板13、第三透光基板24與第一基板21也具有可撓性的話,則可將微開關電子書寫板E製作成曲面書寫板或顯示器。 In the embodiment, the first transparent substrate 11 is a flexible transparent substrate, and the first transparent substrate 11, the second transparent substrate 13 and the third transparent substrate 24 are respectively transparent substrates, but the first The substrate 21 is a light reflecting substrate or a light absorbing substrate that reflects or absorbs incoming light. In addition, the materials of the first transparent substrate 11, the second transparent substrate 13, the third transparent substrate 24, or the first substrate 21 may be plastic or glass, respectively. When the first transparent substrate 11 is a glass substrate, the thickness thereof may be between 0.1 mm and 0.35. Between millimeters (0.1 mm ≦ d ≦ 0.35 mm), the first light-transmitting substrate 11 has a bendable property. Specifically, generally, a thick glass substrate (for example, 0.5 mm to 1.5 mm) has a high hardness and is difficult to be bent or deformed by pressing, but the first transparent substrate 11 has a thickness of only 0.1 mm and 0.35 mm. The glass can exhibit flexible properties and has a pressable and writing function. In some embodiments, the first light transmissive substrate 11 can be, for example but not limited to, a thinned thickness between 0.1 mm and 0.35 mm using a Chemical Mechanical Planarization (CMP) process. In some embodiments, if the second transparent substrate 13, the third transparent substrate 24, and the first substrate 21 are also flexible, the micro-switch electronic tablet E can be fabricated into a curved writing board or a display.

第一膽固醇液晶模組2可對應顯示一顏色。具體來說,微開關電子書寫板E可藉由在第一膽固醇液晶模組2的第一膽固醇液晶層23中添加不同含量的旋光劑,以調配出例如紅(R)、綠(G)或藍(B)等顏色。於此,第一膽固醇液晶模組2對應顯示的顏色可選自於例如但不限於紅、綠、藍的其中一者,或者是其他可見光的顏色。由於膽固醇液晶是通過在向列型液晶中加入旋光劑來達到特殊排列結構,並利用膽固醇液晶分子可在不同電壓差、物理壓力及/或溫度的情況下呈現至少焦錐態(Focal conic state)、平面態(planar state)與垂直態(homeotropic state)等數種不同的穩態或暫態,以達到顯示或清除效果。因此,可藉由使膽固醇液晶的螺旋結構的軸向產生變化,從而使反射部份光線及/或部份光線穿過膽固醇液晶。亦即,可藉由膽固醇液晶分子在不同狀態下所具有的不同光線反射率或穿透率,來達成微開關電子書寫板E的顯示、書寫,甚至是擦拭功能。 The first cholesteric liquid crystal module 2 can display a color correspondingly. Specifically, the micro-switching electronic tablet E can be formulated with different amounts of optically active agents in the first cholesteric liquid crystal layer 23 of the first cholesteric liquid crystal module 2 to formulate, for example, red (R), green (G) or Blue (B) and other colors. Here, the color corresponding to the display of the first cholesteric liquid crystal module 2 may be selected from, for example, but not limited to, one of red, green, and blue, or the color of other visible light. Since the cholesteric liquid crystal achieves a special arrangement by adding an optically active agent to the nematic liquid crystal, and using the cholesteric liquid crystal molecules, it can exhibit at least a Focal conic state under different voltage differences, physical pressures, and/or temperatures. Several different steady-state or transient states, such as the planar state and the homeotropic state, to achieve display or clearing effects. Therefore, the reflected portion of the light and/or part of the light can pass through the cholesteric liquid crystal by changing the axial direction of the helical structure of the cholesteric liquid crystal. That is, the display, writing, and even wiping function of the micro-switching electronic tablet E can be achieved by different light reflectance or transmittance of the cholesteric liquid crystal molecules in different states.

本實施例的微開關電子書寫板E更可包括一電壓控制電路4,其分別與微開關陣列模組1及第一膽固醇液晶模組2電性連接。於此,電壓控制電路4分別與各微開關單元10的透明導電層12及第一膽固醇液晶模組2的第二透明電極層22電性連接。當微開關單元10受到按壓而使透明導電層12與第一透明電極層14接觸而導通微開關單元10時,電壓控制電路4可傳送第一電壓V1經由微開關單元10的透明導電層12與第一透明電極層14,再經由第一導電孔133、第二導電孔241至第三透光基板24之下表面對應的第三透明電極層25,俾使對應的第一膽固醇液晶層23之膽固醇液晶分子轉態,據此顯示書寫軌跡T 或擦拭書寫軌跡T。 The micro-switch electronic tablet E of the embodiment further includes a voltage control circuit 4 electrically connected to the micro-switch array module 1 and the first cholesteric liquid crystal module 2, respectively. The voltage control circuit 4 is electrically connected to the transparent conductive layer 12 of each micro-switch unit 10 and the second transparent electrode layer 22 of the first cholesteric liquid crystal module 2 . When the micro-switch unit 10 is pressed to bring the transparent conductive layer 12 into contact with the first transparent electrode layer 14 to turn on the micro-switch unit 10, the voltage control circuit 4 can transmit the first voltage V1 via the transparent conductive layer 12 of the micro-switch unit 10 and The first transparent electrode layer 14 is further passed through the first conductive hole 133 and the second conductive hole 241 to the third transparent electrode layer 25 corresponding to the lower surface of the third transparent substrate 24, so that the corresponding first cholesteric liquid crystal layer 23 is Cholesterol liquid crystal molecules change state, according to which the writing track T is displayed Or wipe the writing track T.

使用者若要在微開關電子書寫板E上書寫文字或繪製圖案時,則可選擇書寫模式,並利用手指、書寫筆P(圖3B)或其他硬物於微開關電子書寫板E上書寫,此時書寫處(按壓處)對應的微開關單元10將因按壓而使其透明導電層12與第一透明電極層14接觸而導通,電壓控制電路4可經由導通的微開關單元10之透明導電層12傳送第一電壓V1至第一透明電極層14,再經由第一導電孔133與第二導電孔241傳送至第三透光基板24之下表面242的第三透明電極層25,電壓控制電路4也將第二電壓V2(例如為共同電壓,例如但不限於為0伏特)傳送至第二透明電極層22,則第三透明電極層25與第二透明電極層22的電壓差(V1-V2)所產生的電場將迫使對應之第一膽固醇液晶層23的膽固醇液晶分子由焦錐態轉態至平面態,據此可顯示書寫軌跡T。於此,第一電壓V1減去第二電壓V2等於書寫電壓。 If the user wants to write text or draw a pattern on the micro-switch electronic tablet E, the writing mode can be selected, and the finger, the writing pen P (Fig. 3B) or other hard objects are written on the micro-switching electronic writing board E, At this time, the micro-switch unit 10 corresponding to the writing portion (pressing portion) will be turned on by bringing the transparent conductive layer 12 into contact with the first transparent electrode layer 14 by pressing, and the voltage control circuit 4 can be transparently conductive via the turned-on micro-switch unit 10. The layer 12 transmits the first voltage V1 to the first transparent electrode layer 14 and then to the third transparent electrode layer 25 of the lower surface 242 of the third transparent substrate 24 via the first conductive via 133 and the second conductive via 241, and the voltage is controlled. The circuit 4 also transmits a second voltage V2 (for example, a common voltage, such as but not limited to 0 volts) to the second transparent electrode layer 22, and the voltage difference between the third transparent electrode layer 25 and the second transparent electrode layer 22 (V1) The electric field generated by -V2) will force the cholesteric liquid crystal molecules of the corresponding first cholesteric liquid crystal layer 23 to transition from the focal conic state to the planar state, whereby the writing trajectory T can be displayed. Here, the first voltage V1 minus the second voltage V2 is equal to the writing voltage.

舉例來說,在本實施例的微開關電子書寫板E中,在微開關單元10未受到按壓而第三透明電極層25與第二透明電極層22未產生電壓差時,第一膽固醇液晶層23的膽固醇液晶分子為焦錐態排列。此時,入射的光線大部分可經由第一透光基板11、第二透光基板13並穿透第一膽固醇液晶層23,少部分的入射光會產生散射,因此使用者會看見微開關電子書寫板E的底色,例如黑色。當使用者利用手指、書寫筆P或其他硬物於微開關電子書寫板E上書寫而使對應的微開關單元10導通時,第一電壓V1將經由導通的微開關單元10傳送至第三透明電極層25,使得第三透明電極層25與第二透明電極層22之間的電壓差(V1-V2)所生成的電場可使對應之膽固醇液晶分子由原本的焦錐態轉態而處於平面態排列。此時,於按壓處(即第一透光基板11的凹陷處),部分的入射的光線發生布拉格反射,反射的光線(具有特定波長)則由光入射面111射出。同時,微開關電子書寫板E就會在按壓處顯示出反射的光線的顏色,據此顯示出書寫軌跡T(圖1),書寫軌跡T將呈現第一膽固醇液晶模組2所對應的顏色(例如紅色)。因此,若使用者於微開關電子書寫板E上進行書寫文字或繪製圖案以產生書寫軌跡T時,書寫軌跡T將呈現反射的光線對應的顏色,即微開關電子書寫板E對應顯示的顏色。 For example, in the micro-switch electronic tablet E of the embodiment, when the micro-switch unit 10 is not pressed and the third transparent electrode layer 25 and the second transparent electrode layer 22 do not generate a voltage difference, the first cholesterol liquid crystal layer The cholesterol liquid crystal molecules of 23 are in a focal conic state arrangement. At this time, most of the incident light can pass through the first transparent substrate 11 and the second transparent substrate 13 and penetrate the first cholesteric liquid crystal layer 23, and a small portion of the incident light will be scattered, so that the user can see the micro-switching electrons. The background color of the writing board E, such as black. When the user writes on the micro-switch electronic tablet E with a finger, a writing pen P or other hard object to turn on the corresponding micro-switch unit 10, the first voltage V1 will be transmitted to the third transparent via the turned-on micro-switch unit 10. The electrode layer 25 is such that an electric field generated by a voltage difference (V1 - V2) between the third transparent electrode layer 25 and the second transparent electrode layer 22 causes the corresponding cholesteric liquid crystal molecules to be in a plane from the original focal conic state. State arrangement. At this time, at the pressing place (that is, the recess of the first transparent substrate 11), part of the incident light rays are Bragg reflected, and the reflected light rays (having a specific wavelength) are emitted from the light incident surface 111. At the same time, the micro-switching electronic tablet E will display the color of the reflected light at the pressing position, thereby displaying the writing track T (Fig. 1), and the writing track T will present the color corresponding to the first cholesterol liquid crystal module 2 ( For example red). Therefore, if the user writes a text or draws a pattern on the micro-switch electronic tablet E to generate the writing track T, the writing track T will present the color corresponding to the reflected light, that is, the color of the micro-switch electronic tablet E corresponding to the display.

另一方面,使用者若要在微開關電子書寫板E上擦拭書寫軌跡T時,則可選擇擦拭模式(可局部或全部擦拭)。當使用者利用書寫筆P或其他的擦拭工具在要擦拭的書寫軌跡T上(來回)按壓時,此時擦拭處所對應的微開關單元10將因按壓而使微開關單元10之透明導電層12與第一透明電極層14接觸而導通。此時,電壓控制電路4對透明導電層12所傳送第一電壓V1將經由導通的微開關單元10傳導至第一透明電極層14,再經由第一導電孔133與第二導電孔241傳送至第三透光基板24之下表面242的第三透明電極層25。此時,第三透明電極層25與第二透明電極層22之間的壓差(V1-V2)所產生的電場將迫使對應的膽固醇液晶分子由平面態轉態至焦錐態,據此可清除(擦拭)對應的書寫軌跡T。於此,第一電壓V1與第二電壓V2的差為擦拭電壓。 On the other hand, if the user wants to wipe the writing track T on the micro-switch electronic tablet E, the wiping mode (which can be partially or completely wiped) can be selected. When the user presses (back and forth) on the writing track T to be wiped by the writing pen P or other wiping tool, the micro-switching unit 10 corresponding to the wiping position at this time will cause the transparent conductive layer 12 of the micro-switching unit 10 to be pressed. It is in contact with the first transparent electrode layer 14 to be electrically connected. At this time, the first voltage V1 transmitted by the voltage control circuit 4 to the transparent conductive layer 12 is transmitted to the first transparent electrode layer 14 via the turned-on micro-switch unit 10, and then transmitted to the first conductive via 133 and the second conductive via 241 via the first conductive via 133 and the second conductive via 241. The third transparent electrode layer 25 of the lower surface 242 of the third transparent substrate 24. At this time, the electric field generated by the voltage difference (V1 - V2) between the third transparent electrode layer 25 and the second transparent electrode layer 22 will force the corresponding cholesteric liquid crystal molecules to change from a planar state to a focal conic state. Clear (wipe) the corresponding writing track T. Here, the difference between the first voltage V1 and the second voltage V2 is the wiping voltage.

換句話說,在本實施例的微開關電子書寫板E中,當使用者在光入射面111上看見有顏色的書寫軌跡T時,若使用者選擇擦拭模式且利用書寫筆P(或擦拭筆)於書寫軌跡T上擦拭而使對應的微開關單元10導通,此時電壓控制電路4傳送的第一電壓V1將經由微開關單元10傳送至第三透明電極層25,使得第三透明電極層25與第二透明電極層22之間的電壓差(V1-V2)生成的電場可使對應之膽固醇液晶分子由原本的平面態轉態而處於焦錐態排列。此時,於擦拭處(即第一透光基板11的凹陷處),入射的光線大部分可經由第一透光基板11、第二透光基板13、第三透光基板24並穿透第一膽固醇液晶層23,因此使用者在擦拭處就會看見微開關電子書寫板E的底色,藉此清除擦拭處的書寫軌跡T。 In other words, in the micro-switch electronic tablet E of the present embodiment, when the user sees the colored writing track T on the light incident surface 111, if the user selects the wiping mode and uses the writing pen P (or the wiping pen) Wiping on the writing track T to turn on the corresponding micro-switch unit 10, at which time the first voltage V1 transmitted by the voltage control circuit 4 will be transmitted to the third transparent electrode layer 25 via the micro-switch unit 10, so that the third transparent electrode layer The electric field generated by the voltage difference (V1 - V2) between the second transparent electrode layer 22 and the second transparent electrode layer 22 allows the corresponding cholesteric liquid crystal molecules to be in a focal conic state from the original planar state. At this time, at the wiping place (ie, the recess of the first transparent substrate 11), most of the incident light can pass through the first transparent substrate 11, the second transparent substrate 13, and the third transparent substrate 24 and penetrate the first A cholesteric liquid crystal layer 23, so that the user can see the undertone of the microswitch electronic tablet E at the wiping place, thereby clearing the writing track T at the wiping place.

此外,在一些實施例中,電壓控制電路4也可直接與所有的第三透明電極層25電性連接。如此一來,當使用者藉由按壓微開關電子書寫板E上的一全清除鍵(虛擬或實體按鍵,圖未繪示)而將微開關電子書寫板E切換至一全清除模式時,電壓控制電路4可將一清除電壓直接傳送至所有的第三透明電極層25(不需經由微開關單元10),藉此驅動全部的液晶控制區231的膽固醇液晶轉態至焦錐態,據以清除整個畫面上所有的書寫軌跡T。當然,電壓控制電路4也可直接將另一型態的清除電壓送至第二透明電極層22,據以清除整個畫面上所有的書寫軌跡T。 In addition, in some embodiments, the voltage control circuit 4 can also be electrically connected directly to all of the third transparent electrode layers 25. In this way, when the user switches the micro-switch electronic tablet E to a full-clear mode by pressing a full clear button (virtual or physical button, not shown) on the micro-switch electronic tablet E, the voltage The control circuit 4 can directly transmit a clear voltage to all of the third transparent electrode layers 25 (without passing through the micro-switch unit 10), thereby driving the cholesteric liquid crystals of all the liquid crystal control regions 231 to the focal conic state. Clear all writing tracks T on the entire screen. Of course, the voltage control circuit 4 can also directly send another type of clear voltage to the second transparent electrode layer 22, thereby clearing all the writing tracks T on the entire screen.

承上,在本實施例的微開關電子書寫板E中,由於微開關陣列模組1與第一膽固醇液晶模組2的結構相當簡單,製作成本相對低廉。而且,本實施例的微開關陣列模組1與第一膽固醇液晶模組2僅須相互疊合而無須精準定位,微開關陣列模組1即可控制第一膽固醇液晶模組2的顯示,製作工序亦相當簡便。換句話說,當微開關單元10受到按壓而使透明導電層12與第一透明電極層14接觸,進而使微開關單元10導通時,電壓控制電路4可經由微開關單元10的透明導電層12傳送控制電壓(第一電壓V1)至第三透明電極層25,俾使對應的第一膽固醇液晶層23之膽固醇液晶分子轉態,據此即可顯示書寫軌跡T或擦拭書寫軌跡T。因此,本實施例的具有偵測書寫位置或擦拭位置的功能的微開關電子書寫板E,其結構相當簡單,製作成本相對低廉,且製作工序亦相當簡便。 In the micro-switch electronic tablet E of the embodiment, the structure of the micro-switch array module 1 and the first cholesteric liquid crystal module 2 is relatively simple, and the manufacturing cost is relatively low. Moreover, the micro-switch array module 1 and the first cholesteric liquid crystal module 2 of the embodiment need only be superimposed on each other without precise positioning, and the micro-switch array module 1 can control the display of the first cholesteric liquid crystal module 2, and The process is also quite simple. In other words, when the micro-switch unit 10 is pressed to bring the transparent conductive layer 12 into contact with the first transparent electrode layer 14, thereby turning on the micro-switch unit 10, the voltage control circuit 4 can pass through the transparent conductive layer 12 of the micro-switch unit 10. The control voltage (first voltage V1) is transmitted to the third transparent electrode layer 25, and the cholesteric liquid crystal molecules of the corresponding first cholesteric liquid crystal layer 23 are rotated, whereby the writing trajectory T or the wiping writing trajectory T can be displayed. Therefore, the micro-switch electronic tablet E having the function of detecting the writing position or the wiping position of the embodiment has a relatively simple structure, a relatively low manufacturing cost, and a relatively simple manufacturing process.

請參照圖3C所示,本實施例的微開關電子書寫板E與前述實施例的微開關電子書寫板E其元件組成及連接關係大致相同。不同之處在於,本實施例的第一基板21為透光基板,且微開關電子書寫板E更可包括一背板5,背板5設置於第一基板21背向第一膽固醇液晶層23的表面212上。背板5可為黑色的光吸收板或包含光吸收層,或者背板5也可為白色的光反射板或包含光反射層。當背板5為黑色的光吸收板或包含光吸收層時,其會吸收穿過表面212的光線,使微開關電子書寫板E成為一黑板。在一些實施例中,黑色光吸收板(或光吸收膜)的材料可與液晶顯示裝置的黑色矩陣(black matrix)的材料相同。另外,當背板5為白色的光反射板或包含光反射層時,其係反射穿過表面212的光線,使微開關電子書寫板E成為一白板。在一些實施例中,白色光反射板(或白色光反射膜)的材料例如可包含金屬、金屬氧化物、高反射漆(白漆)、或其組合,本發明並不限定。或者,在不同的實施例中,背板5的顏色也不限定為黑色或白色,其可為其他顏色或多種顏色的組合,並不限制。 Referring to FIG. 3C, the micro-switch electronic tablet E of the present embodiment has substantially the same component composition and connection relationship as the micro-switch electronic tablet E of the foregoing embodiment. The difference is that the first substrate 21 of the embodiment is a light-transmitting substrate, and the micro-switching electronic tablet E can further include a backing plate 5 disposed on the first substrate 21 facing away from the first cholesteric liquid crystal layer 23 On the surface 212. The backing plate 5 may be a black light absorbing plate or a light absorbing layer containing the light absorbing layer, or the backing plate 5 may also be white or include a light reflecting layer. When the backing plate 5 is a black light absorbing plate or contains a light absorbing layer, it absorbs light passing through the surface 212, making the microswitch electronic tablet E a blackboard. In some embodiments, the material of the black light absorbing plate (or light absorbing film) may be the same as the material of the black matrix of the liquid crystal display device. In addition, when the back sheet 5 is a white light reflecting plate or contains a light reflecting layer, it reflects light passing through the surface 212, so that the microswitch electronic tablet E becomes a white board. In some embodiments, the material of the white light reflecting plate (or white light reflecting film) may include, for example, a metal, a metal oxide, a high reflective paint (white paint), or a combination thereof, which is not limited in the present invention. Alternatively, in different embodiments, the color of the back sheet 5 is not limited to black or white, and may be other colors or a combination of colors, and is not limited.

請參照圖4A與圖41B所示,其分別為本發明所提供之微開關電子書寫板的另一實施例的結構示意圖。本實施例的微開關電子書寫板E與前述實施例的微開關電子書寫板E其元件組成及連接關係大致相同。不同之處在於,本實施例的微開關電子書寫板E除了包含前述實施例的第一膽固醇液晶模組2 外,更在第一膽固醇液晶模組2之第一基板21的另一表面212上設置有一間隔配置的第四透明電極層26,且各第四透明電極層26電性連接於各第三透明電極層25(圖4B)。 Please refer to FIG. 4A and FIG. 41B , which are respectively schematic structural diagrams of another embodiment of the micro-switch electronic tablet provided by the present invention. The micro-switch electronic tablet E of the present embodiment has substantially the same component composition and connection relationship as the micro-switch electronic tablet E of the foregoing embodiment. The difference is that the micro-switch electronic tablet E of the embodiment includes the first cholesteric liquid crystal module 2 of the foregoing embodiment. Further, a fourth transparent electrode layer 26 is disposed on the other surface 212 of the first substrate 21 of the first cholesteric liquid crystal module 2, and each of the fourth transparent electrode layers 26 is electrically connected to each of the third transparent layers. Electrode layer 25 (Fig. 4B).

除此之外,本實施例的微開關電子書寫板E更包括一第二膽固醇液晶模組3,且第二膽固醇液晶模組3與第一膽固醇液晶模組2重疊設置。其中,第二膽固醇液晶模組3係設置於第一膽固醇液晶模組2遠離微開關陣列模組1的一側,且第一膽固醇液晶模組2與第二膽固醇液晶模組3對應顯示的顏色不同。 In addition, the micro-switch electronic tablet E of the embodiment further includes a second cholesteric liquid crystal module 3, and the second cholesteric liquid crystal module 3 is overlapped with the first cholesteric liquid crystal module 2. The second cholesteric liquid crystal module 3 is disposed on a side of the first cholesteric liquid crystal module 2 away from the micro-switch array module 1, and the color corresponding to the first cholesteric liquid crystal module 2 and the second cholesteric liquid crystal module 3 is displayed. different.

於此,係假設第一膽固醇液晶模組2對應的顏色為紅色,且第二膽固醇液晶模組3對應的顏色為綠色為例。如圖4A與圖4B所示,第二膽固醇液晶模組3包含一第二基板31、一第五透明電極層32及一第二膽固醇液晶層33。於此,第五透明電極層32可為共同電極,並全面性地設置於第二基板31面對第二膽固醇液晶層33的表面311上,而第二膽固醇液晶層33設置於第五透明電極層32上。另外,由於第一基板21面對第二膽固醇液晶層33的表面212上設置間隔配置的第四透明電極層26,使得第二膽固醇液晶層33夾置於第四透明電極層26與第五透明電極層32之間。其中,第二膽固醇液晶模組3係藉由第一基板21而與第一膽固醇液晶模組2相互疊合,以使第二膽固醇液晶層33介於第一基板21與第二基板31之間。第二膽固醇液晶層33可包括多個液晶控制區331,且各液晶控制區331分別與各微開關單元10、各透明導電層12、各第一透明電極層14、各間隔配置的第三透明電極層25及各間隔配置的第四透明電極層26對應設置。 Here, it is assumed that the color corresponding to the first cholesteric liquid crystal module 2 is red, and the color corresponding to the second cholesteric liquid crystal module 3 is green. As shown in FIG. 4A and FIG. 4B, the second cholesteric liquid crystal module 3 includes a second substrate 31, a fifth transparent electrode layer 32, and a second cholesteric liquid crystal layer 33. Here, the fifth transparent electrode layer 32 may be a common electrode, and is disposed integrally on the surface 311 of the second substrate 31 facing the second cholesteric liquid crystal layer 33, and the second cholesteric liquid crystal layer 33 is disposed on the fifth transparent electrode. On layer 32. In addition, since the first substrate 21 faces the fourth transparent electrode layer 26 disposed on the surface 212 of the second cholesteric liquid crystal layer 33, the second cholesteric liquid crystal layer 33 is sandwiched between the fourth transparent electrode layer 26 and the fifth transparent layer. Between the electrode layers 32. The second cholesteric liquid crystal module 3 is overlapped with the first cholesteric liquid crystal module 2 by the first substrate 21 such that the second cholesteric liquid crystal layer 33 is interposed between the first substrate 21 and the second substrate 31. . The second cholesteric liquid crystal layer 33 may include a plurality of liquid crystal control regions 331, and each of the liquid crystal control regions 331 and the respective micro-switching units 10, the transparent conductive layers 12, the first transparent electrode layers 14, and the third transparent arrangement The electrode layer 25 and the fourth transparent electrode layer 26 disposed at intervals are provided correspondingly.

本實施例之第一透光基板11、第二透光基板13、第三透光基板24、第一基板21、或第二基板31的材料可為塑膠或玻璃,而透明導電層12、第一透明電極層14、第二透明電極層22、第三透明電極層25、第四透明電極層26或第五透明電極層32的材料可為透明導電材料或石墨烯,皆不限制。另外,本實施例的第一基板21為透光基板,但第二基板31為光反射基板或光吸收基板而具有光反射或光吸收的功能。在一些實施例中,可如圖3C所示,當第二基板31為透光基板時,可在第二基板31遠離第二膽固醇液晶層33的表面312再設 置一背板5,以吸收或反射光線。 The material of the first transparent substrate 11, the second transparent substrate 13, the third transparent substrate 24, the first substrate 21, or the second substrate 31 of the present embodiment may be plastic or glass, and the transparent conductive layer 12, The material of a transparent electrode layer 14, the second transparent electrode layer 22, the third transparent electrode layer 25, the fourth transparent electrode layer 26 or the fifth transparent electrode layer 32 may be a transparent conductive material or graphene, and is not limited. Further, the first substrate 21 of the present embodiment is a light-transmitting substrate, but the second substrate 31 is a light-reflecting substrate or a light-absorbing substrate and has a function of light reflection or light absorption. In some embodiments, as shown in FIG. 3C, when the second substrate 31 is a light-transmitting substrate, the second substrate 31 may be further disposed away from the surface 312 of the second cholesteric liquid crystal layer 33. A backing plate 5 is placed to absorb or reflect light.

另外,本實施例的各第三透明電極層25分別與對應的各第四透明電極層26電性連接,因此,傳送至第三透明電極層25的電壓可同時傳送至對應的第四透明電極層26。此外,本實施例的電壓控制電路4分別與透明導電層12、第二透明電極層22及第五透明電極層32電性連接。於此,電壓控制電路4傳送至透明導電層12的第一電壓V1可為書寫電壓或擦拭電壓,且電壓控制電路4傳送至第二透明電極層22及第五透明電極層32的第二電壓V2與第三電壓V3可為共同電壓(例如0伏特)、書寫電壓或擦拭電壓,視書寫或擦拭而定。 In addition, each of the third transparent electrode layers 25 of the present embodiment is electrically connected to the corresponding fourth transparent electrode layer 26, and thus, the voltage transmitted to the third transparent electrode layer 25 can be simultaneously transmitted to the corresponding fourth transparent electrode. Layer 26. In addition, the voltage control circuit 4 of the present embodiment is electrically connected to the transparent conductive layer 12, the second transparent electrode layer 22, and the fifth transparent electrode layer 32, respectively. Here, the first voltage V1 transmitted by the voltage control circuit 4 to the transparent conductive layer 12 may be a writing voltage or a wiping voltage, and the voltage control circuit 4 transmits the second voltage to the second transparent electrode layer 22 and the fifth transparent electrode layer 32. V2 and the third voltage V3 may be a common voltage (for example, 0 volt), a writing voltage, or a wiping voltage, depending on writing or wiping.

如圖4B所示,在本實施例之微開關電子書寫板E中,當微開關單元10受到按壓而使微開關單元10導通時,電壓控制電路4可經由微開關單元10施加第一電壓V1至第一膽固醇液晶模組2及/或第二膽固醇液晶模組3,據此顯示書寫軌跡T或擦拭書寫軌跡T。具體來說,假設使用者在微開關電子書寫板E上書寫,並且要讓書寫軌跡T呈現第一膽固醇液晶模組2所對應的紅色時,當書寫筆P在光入射面111上按壓、書寫,使得按壓處對應的微開關單元10導通時,第一電壓V1可經由微開關單元10之透明導電層12傳送至第三透光基板24之表面242的第三透明電極層25,藉此控制第一膽固醇液晶模組2對應的膽固醇液晶分子轉態至平面態,使書寫軌跡顯示出對應的紅色。此時,第一電壓V1也會經由第一透明電極層14而傳送至第四透明電極層26,為了不顯示第二膽固醇液晶模組3所對應的綠色,則電壓控制電路4不會傳送共同電壓,而是傳送與第一電壓V1相同的第三電壓V3至第五透明電極層32,使得對應按壓處的第四透明電極層26與第五透明電極層32的壓差為0,藉此使得微開關單元10的導通不影響對應之第二膽固醇液晶層33的液晶控制區331,因此,書寫軌跡T就不會顯示第二膽固醇液晶模組3所對應的綠色。 As shown in FIG. 4B, in the micro-switch electronic tablet E of the present embodiment, when the micro-switch unit 10 is pressed to turn on the micro-switch unit 10, the voltage control circuit 4 can apply the first voltage V1 via the micro-switch unit 10. Up to the first cholesteric liquid crystal module 2 and/or the second cholesteric liquid crystal module 3, the writing trajectory T or the wiping writing trajectory T is displayed accordingly. Specifically, assuming that the user writes on the micro-switch electronic tablet E, and the writing track T is to be red corresponding to the first cholesterol liquid crystal module 2, when the writing pen P is pressed and written on the light incident surface 111, When the corresponding micro-switch unit 10 is turned on, the first voltage V1 can be transmitted to the third transparent electrode layer 25 of the surface 242 of the third transparent substrate 24 via the transparent conductive layer 12 of the micro-switch unit 10, thereby controlling The cholesteric liquid crystal molecules corresponding to the first cholesteric liquid crystal module 2 are turned to a planar state, so that the writing trajectory shows a corresponding red color. At this time, the first voltage V1 is also transmitted to the fourth transparent electrode layer 26 via the first transparent electrode layer 14. In order not to display the green corresponding to the second cholesteric liquid crystal module 3, the voltage control circuit 4 does not transmit the common Voltage, but transmitting the same third voltage V3 to fifth transparent electrode layer 32 as the first voltage V1, so that the pressure difference between the fourth transparent electrode layer 26 and the fifth transparent electrode layer 32 corresponding to the pressing is 0, thereby The conduction of the micro-switch unit 10 does not affect the liquid crystal control region 331 of the corresponding second cholesteric liquid crystal layer 33. Therefore, the writing trajectory T does not display the green color corresponding to the second cholesteric liquid crystal module 3.

相反的,若使用者選擇綠色時,雖然第一電壓V1可經由微開關單元10傳送至第三透明電極層25,但是,因為電壓控制電路4不會傳送共同電壓,而會傳送與第一電壓V1相同的第二電壓V2至第二透明電極層22,使得第三透明電極層25與第二透明電極層22的壓差為0,則書寫軌跡T就不會呈現第一膽固醇液晶模組2所對應的紅色;但是,第一電壓V1會經由第三透明電極層 25而傳送至第四透明電極層26,使得第四透明電極層26與第五透明電極層32(共同電壓)之間具有壓差而使第二膽固醇液晶層33對應的膽固醇液晶分子轉態至平面態,據此使書寫軌跡T顯示出第二膽固醇液晶模組3所對應的綠色。此外,若第一膽固醇液晶模組2與第二膽固醇液晶模組3中的膽固醇液晶分子同時為平面態的話,則書寫軌跡T將顯示紅色、綠色的混合色(藍色),藉此使微開關電子書寫板E可顯示多彩的書寫軌跡T。同樣地,在擦拭模式時,使用者也可依循上述控制原理選擇擦拭某一顏色的書寫軌跡,或者,選擇將兩種顏色之混合色的書寫軌跡皆擦拭掉,具體控制方法可參照上述的說明。 Conversely, if the user selects green, although the first voltage V1 can be transmitted to the third transparent electrode layer 25 via the micro-switch unit 10, since the voltage control circuit 4 does not transmit the common voltage, it transmits the first voltage. When the voltage difference between the third transparent electrode layer 25 and the second transparent electrode layer 22 is 0, the writing track T does not present the first cholesteric liquid crystal module 2 Corresponding red; however, the first voltage V1 will pass through the third transparent electrode layer And transmitting to the fourth transparent electrode layer 26 such that there is a pressure difference between the fourth transparent electrode layer 26 and the fifth transparent electrode layer 32 (common voltage) to cause the corresponding cholesteric liquid crystal molecules of the second cholesteric liquid crystal layer 33 to be transferred to The planar state, according to which the writing track T shows the green color corresponding to the second cholesteric liquid crystal module 3. In addition, if the cholesteric liquid crystal molecules in the first cholesteric liquid crystal module 2 and the second cholesteric liquid crystal module 3 are in a planar state at the same time, the writing trajectory T will display a mixed color of blue and green (blue), thereby making the micro The switch electronic tablet E can display a colorful writing track T. Similarly, in the wiping mode, the user can also select to wipe the writing track of a certain color according to the above control principle, or select the writing track of the mixed color of the two colors to be wiped off. For the specific control method, refer to the above description. .

此外,在一些實施例中,也可在第二膽固醇液晶模組3遠離第一膽固醇液晶模組2的一側再疊置一第三膽固醇液晶模組(未繪示),且使第三膽固醇液晶模組、第一膽固醇液晶模組2與第二膽固醇液晶模組3彼此對應的顏色皆不相同,藉此使書寫軌跡T的顏色更呈現多樣化。 In addition, in some embodiments, a third cholesteric liquid crystal module (not shown) may be stacked on the side of the second cholesteric liquid crystal module 3 away from the first cholesteric liquid crystal module 2, and the third cholesterol may be made. The colors of the liquid crystal module, the first cholesteric liquid crystal module 2 and the second cholesteric liquid crystal module 3 are different from each other, thereby making the color of the writing trajectory T more diverse.

圖5A與圖5B分別為本發明所提供之微開關電子書寫板的又一實施例的示意圖。本實施例的微開關電子書寫板E與前述實施例的微開關電子書寫板E其元件組成及連接關係大致相同。不同之處在於,本實施例的微開關電子書寫板E除了包含前述實施例的微開關陣列模組1與第一膽固醇液晶模組2外,本實施例的第二膽固醇液晶模組3的結構有些不同。 5A and 5B are respectively schematic views of still another embodiment of the micro-switch electronic tablet provided by the present invention. The micro-switch electronic tablet E of the present embodiment has substantially the same component composition and connection relationship as the micro-switch electronic tablet E of the foregoing embodiment. The difference is that the micro-switch electronic tablet E of the embodiment includes the structure of the second cholesteric liquid crystal module 3 of the present embodiment, except the micro-switch array module 1 and the first cholesteric liquid crystal module 2 of the foregoing embodiment. slightly different.

於此,仍以第一膽固醇液晶模組2對應的顏色為紅色,且第二膽固醇液晶模組3對應的顏色為綠色為例來說明。如圖5A與圖5B所示,第二膽固醇液晶模組3包含一第二基板31、一第五透明電極層32及一第二膽固醇液晶層33、一第四透光基板34與第四透明電極層35。於此,第五透明電極層32仍為共同電極,並全面性地設置於第二基板31面對第二膽固醇液晶層33的表面311上,而第二膽固醇液晶層33設置於第五透明電極層32上。另外,第四透光基板34設置於第二膽固醇液晶層33上,且第四透光基板34面對第二膽固醇液晶層33的一表面341上係設置有間隔配置的第四透明電極層35,因此,第二膽固醇液晶層33夾置於第四透明電極層35與第五透明電極層32之間。其中,第二膽固醇液晶模組3係藉由第一基板21及第四透光基板34而與第一膽固醇液晶模組2相互疊合。此外,第二膽固醇液晶層33可包括多個液晶控制區331,且 各液晶控制區331分別與各微開關單元10、各透明導電層12、各第一透明電極層14、各間隔配置的第三透明電極層25與各間隔配置的第四透明電極層35對應設置。 Here, the color corresponding to the first cholesteric liquid crystal module 2 is red, and the color corresponding to the second cholesteric liquid crystal module 3 is green. As shown in FIG. 5A and FIG. 5B, the second cholesteric liquid crystal module 3 includes a second substrate 31, a fifth transparent electrode layer 32, a second cholesteric liquid crystal layer 33, a fourth transparent substrate 34, and a fourth transparent layer. Electrode layer 35. Here, the fifth transparent electrode layer 32 is still a common electrode, and is disposed integrally on the surface 311 of the second substrate 31 facing the second cholesteric liquid crystal layer 33, and the second cholesteric liquid crystal layer 33 is disposed on the fifth transparent electrode. On layer 32. In addition, the fourth transparent substrate 34 is disposed on the second cholesteric liquid crystal layer 33, and the fourth transparent electrode layer 34 is disposed on a surface 341 of the second luminescent liquid crystal layer 33 with a spaced-apart fourth transparent electrode layer 35. Therefore, the second cholesteric liquid crystal layer 33 is interposed between the fourth transparent electrode layer 35 and the fifth transparent electrode layer 32. The second cholesteric liquid crystal module 3 is superposed on the first cholesteric liquid crystal module 2 by the first substrate 21 and the fourth transparent substrate 34 . Further, the second cholesteric liquid crystal layer 33 may include a plurality of liquid crystal control regions 331, and Each of the liquid crystal control regions 331 is provided corresponding to each of the microswitch units 10, the transparent conductive layers 12, the first transparent electrode layers 14, and the third transparent electrode layers 25 disposed at intervals, and the fourth transparent electrode layers 35 disposed at intervals. .

本實施例的第一基板21為透光基板,但第二基板31為光反射基板或光吸收基板而具有光反射或光吸收的功能。在一些實施例中,可如圖3C所示,當第二基板31為透光基板時,可在第二基板31遠離第二膽固醇液晶層33的表面312再設置一背板5,以吸收或反射光線。另外,本實施例的第四透明電極層35係電性連接於對應的第三透明電極層25(圖5B),因此,傳送至第三透明電極層25的電壓可同時傳送至對應的第四透明電極層35。此外,本實施例的電壓控制電路4分別與透明導電層12、第二透明電極層22及第五透明電極層32電性連接。於此,電壓控制電路4傳送至透明導電層12的第一電壓V1可為書寫電壓或擦拭電壓,且電壓控制電路4對應傳送至第二透明電極層22、第五透明電極層32的第二電壓V2、第三電壓V3可為共同電壓(例如0伏特)、書寫電壓或擦拭電壓,視書寫或擦拭而定。 The first substrate 21 of the present embodiment is a light-transmitting substrate, but the second substrate 31 is a light-reflecting substrate or a light-absorbing substrate and has a function of light reflection or light absorption. In some embodiments, as shown in FIG. 3C, when the second substrate 31 is a light-transmitting substrate, a back plate 5 may be further disposed on the surface 312 of the second substrate 31 away from the second cholesteric liquid crystal layer 33 to absorb or Reflecting light. In addition, the fourth transparent electrode layer 35 of the embodiment is electrically connected to the corresponding third transparent electrode layer 25 (FIG. 5B). Therefore, the voltage transmitted to the third transparent electrode layer 25 can be simultaneously transmitted to the corresponding fourth. Transparent electrode layer 35. In addition, the voltage control circuit 4 of the present embodiment is electrically connected to the transparent conductive layer 12, the second transparent electrode layer 22, and the fifth transparent electrode layer 32, respectively. Here, the first voltage V1 that the voltage control circuit 4 transmits to the transparent conductive layer 12 may be a writing voltage or a wiping voltage, and the voltage control circuit 4 corresponds to the second transparent electrode layer 22 and the second transparent electrode layer 32. The voltage V2 and the third voltage V3 may be a common voltage (for example, 0 volt), a writing voltage, or a wiping voltage, depending on writing or wiping.

此外,本實施例之第一透光基板11、第二透光基板13、第三透光基板24、第四透光基板34、第一基板21、或第二基板31的材料可為塑膠或玻璃的材料,而透明導電層12、第一透明電極層14、第二透明電極層22、第三透明電極層25、第五透明電極層32、或第四透明電極層35的材料為透明導電材料或石墨烯,皆不限制。 In addition, the materials of the first transparent substrate 11, the second transparent substrate 13, the third transparent substrate 24, the fourth transparent substrate 34, the first substrate 21, or the second substrate 31 of the embodiment may be plastic or The material of the glass, and the material of the transparent conductive layer 12, the first transparent electrode layer 14, the second transparent electrode layer 22, the third transparent electrode layer 25, the fifth transparent electrode layer 32, or the fourth transparent electrode layer 35 is transparent conductive Materials or graphene are not limited.

如圖5B所示,在本實施例之微開關電子書寫板E中,當微開關單元10受到按壓而使微開關單元10導通時,電壓控制電路4可經由微開關單元10施加第一電壓V1至第一膽固醇液晶模組2及/或第二膽固醇液晶模組3,據此顯示書寫軌跡T或擦拭書寫軌跡T。具體來說,假設使用者在微開關電子書寫板E上書寫,並且要讓書寫軌跡T呈現第一膽固醇液晶模組2所對應的紅色時,當書寫筆P在光入射面111上按壓、書寫,使得按壓處對應的微開關單元10導通時,第一電壓V1可經由微開關單元10之透明導電層12傳送至第三透光基板24之下表面242的第三透明電極層25,藉此控制第一膽固醇液晶模組2對應的膽固醇液晶分子轉態至平面態,使書寫軌跡顯示出對應的紅色。此時,第一電 壓V1也會經由第三透明電極層25而傳送至第四透明電極層35,為了不顯示第二膽固醇液晶模組3所對應的綠色,則電壓控制電路4不會傳送共同電壓,而是傳送與第一電壓V1相同的第三電壓V3至第五透明電極層32,使得對應按壓處的第四透明電極層35與第五透明電極層32的壓差為0,藉此使得微開關單元10的導通不影響對應之第二膽固醇液晶層33的液晶控制區331,因此,書寫軌跡T就不會顯示第二膽固醇液晶模組3所對應的綠色。 As shown in FIG. 5B, in the micro-switch electronic tablet E of the present embodiment, when the micro-switch unit 10 is pressed to turn on the micro-switch unit 10, the voltage control circuit 4 can apply the first voltage V1 via the micro-switch unit 10. Up to the first cholesteric liquid crystal module 2 and/or the second cholesteric liquid crystal module 3, the writing trajectory T or the wiping writing trajectory T is displayed accordingly. Specifically, assuming that the user writes on the micro-switch electronic tablet E, and the writing track T is to be red corresponding to the first cholesterol liquid crystal module 2, when the writing pen P is pressed and written on the light incident surface 111, When the corresponding micro-switch unit 10 is turned on, the first voltage V1 can be transmitted to the third transparent electrode layer 25 of the lower surface 242 of the third transparent substrate 24 via the transparent conductive layer 12 of the micro-switch unit 10, thereby The cholesteric liquid crystal molecules corresponding to the first cholesteric liquid crystal module 2 are controlled to be in a planar state, so that the writing trajectory shows a corresponding red color. At this time, the first electricity The voltage V1 is also transmitted to the fourth transparent electrode layer 35 via the third transparent electrode layer 25. In order not to display the green color corresponding to the second cholesteric liquid crystal module 3, the voltage control circuit 4 does not transmit a common voltage but transmits The third voltage V3 to the fifth transparent electrode layer 32 are the same as the first voltage V1, so that the voltage difference between the fourth transparent electrode layer 35 and the fifth transparent electrode layer 32 corresponding to the pressing portion is 0, thereby causing the micro-switch unit 10 The conduction does not affect the liquid crystal control region 331 of the corresponding second cholesteric liquid crystal layer 33. Therefore, the writing trajectory T does not display the green color corresponding to the second cholesteric liquid crystal module 3.

相反的,若使用者選擇綠色時,雖然第一電壓V1可經由微開關單元10傳送至第三透明電極層25,但是,因為電壓控制電路4不會傳送共同電壓,而會傳送與第一電壓V1相同的第二電壓V2至第二透明電極層22,使得第三透明電極層25與第二透明電極層22的壓差為0,則書寫軌跡T就不會呈現第一膽固醇液晶模組2所對應的紅色;但是,第一電壓V1會經由第三透明電極層25傳送至第四透明電極層35,使得第四透明電極層35與第五透明電極層32(共同電壓)之間具有壓差而使第二膽固醇液晶層33對應的膽固醇液晶分子轉態至平面態,據此使書寫軌跡T顯示出第二膽固醇液晶模組3所對應的綠色。此外,若第一膽固醇液晶模組2與第二膽固醇液晶模組3中的膽固醇液晶分子同時為平面態的話,則書寫軌跡T將顯示紅色、綠色的混合色(藍色),藉此使微開關電子書寫板E可顯示多彩的書寫軌跡T。同樣地,在擦拭模式時,使用者也可依循上述控制原理選擇擦拭某一顏色的書寫軌跡,或者,選擇將兩種顏色之混合色的書寫軌跡皆擦拭掉,具體控制方法可參照上述的說明。 Conversely, if the user selects green, although the first voltage V1 can be transmitted to the third transparent electrode layer 25 via the micro-switch unit 10, since the voltage control circuit 4 does not transmit the common voltage, it transmits the first voltage. When the voltage difference between the third transparent electrode layer 25 and the second transparent electrode layer 22 is 0, the writing track T does not present the first cholesteric liquid crystal module 2 Corresponding red; however, the first voltage V1 is transmitted to the fourth transparent electrode layer 35 via the third transparent electrode layer 25 such that there is a voltage between the fourth transparent electrode layer 35 and the fifth transparent electrode layer 32 (common voltage) Poorly, the cholesteric liquid crystal molecules corresponding to the second cholesteric liquid crystal layer 33 are turned to a planar state, whereby the writing trajectory T shows the green color corresponding to the second cholesteric liquid crystal module 3. In addition, if the cholesteric liquid crystal molecules in the first cholesteric liquid crystal module 2 and the second cholesteric liquid crystal module 3 are in a planar state at the same time, the writing trajectory T will display a mixed color of blue and green (blue), thereby making the micro The switch electronic tablet E can display a colorful writing track T. Similarly, in the wiping mode, the user can also select to wipe the writing track of a certain color according to the above control principle, or select the writing track of the mixed color of the two colors to be wiped off. For the specific control method, refer to the above description. .

在一些實施例中,也可在第二膽固醇液晶模組3遠離第一膽固醇液晶模組2的一側再疊置一第三膽固醇液晶模組(未繪示),且使第三膽固醇液晶模組、第一膽固醇液晶模組2與第二膽固醇液晶模組3彼此對應的顏色皆不相同,藉此使書寫軌跡T的顏色更呈現多樣化。 In some embodiments, a third cholesteric liquid crystal module (not shown) may be stacked on the side of the second cholesteric liquid crystal module 3 away from the first cholesteric liquid crystal module 2, and the third cholesteric liquid crystal mode may be The colors of the group, the first cholesteric liquid crystal module 2 and the second cholesteric liquid crystal module 3 are different from each other, thereby making the color of the writing trajectory T more diverse.
