Below in the embedded touch control display floater of the explanation present invention, a pixel operation is in display pattern and control mode touch mode Type of drive.Fig. 3 a is the schematic diagram in display pattern for the pixel operation of Fig. 2.Fig. 3 b is the pixel operation of Fig. 2 in control mode touch mode Schematic diagram.When operation is in display pattern, as shown in Figure 3 a, second switch element t2 opens (on), and common electrode 32 is together Turned on electrode wires 27, common electrode line 27 provides a fixing shared voltage (vcom) to common electrode 32, now first opens Close element t1 and open (on), pixel electrode 31 is turned on data wire 24, and display data signal vdata is delivered to pixel by data wire 24 Electrode 31, to update display picture.When operation is in control mode touch mode, as shown in Figure 3 b, second switch element t2 closes (off), Together with turning between electrode wires 27, common electrode 32 is in floating (flaoting) current potential to common electrode 32, and now One switch element t1 opens (on), and pixel electrode 31 is turned on data wire 24, and touch-control drive signal vt is sent to by data wire 24 Pixel electrode 31, and receive the sensing result of touch sense signals vr from pixel electrode 31, to judge whether to touch.
In above-mentioned type of drive, each pixel electrode 31 can sending and receiving touch-control drive signal vt and touch sense signals Vr, therefore pixel electrode 31 are equivalent to the touch-control sensing electrode of a least unit under control mode touch mode, because sensing area is remote Less as touch-control sensing electrode than known technology is come with an electrode block, therefore can do finer touch-control sensing.In addition, working as When display data signal vdata inputs pixel electrode 31 by data wire 24, common electrode 32 maintains the shared voltage of definite value vcom.Now, the pressure reduction between pixel electrode 31 and common electrode 32 can control liquid crystal display cells clcShow specific GTG. When being converted to control mode touch mode, because the current potential of common electrode 32 is quick condition (floating), that is, non-definite value, so Even if touch-control drive signal vt and touch sense signals vr input pixel electrode 31 by data wire 24 and change pixel electrode The gray scale voltage of 31 script, but the pressure reduction between pixel electrode 31 and common electrode 32 still can maintain not because of coupling effect Become, therefore liquid crystal display cells clc still can maintain the GTG of original display, can't affect display picture because of touch-control.
Fig. 4 is the time diagram showing the pixel of Fig. 2 under display pattern with control mode touch mode driving.It is assumed herein that first It is to open (on) that the control terminal of switch element t1 and second switch element t2 is in during high potential, and being in during electronegative potential is to close (off) explaining (such as n-type transistor).However, according to the type of switch element, switch element can also be under electronegative potential Open, under high potential, close (such as p-type transistor).As shown in figure 4, in display mode, the current potential of gate line 25 is in height Current potential is switched with the catch cropping of electronegative potential, and gate line 25 in high potential, open, by display data signal vdata by first switch t1 Current potential writing pixel electrode 31, when switching to electronegative potential, first switch t1 is closed, and pixel electrode 31 maintains data signal vdata Current potential.Under display pattern, secondary gate line 26 maintains high potential, and therefore second switch element t2 keeps it turned on, and makes common electrode 32 Maintain the common voltage vcom current potential of definite value.
It is assumed that scan mode (i.e. the 3rd scanning side of gate line full scan simultaneously for specific region under control mode touch mode Formula, after specific features are specified in), gate line 25 can maintain high potential to pass during this period to open first switch t1, data wire 24 (in figure amplitude is less than data signal and frequency is higher than data to send and receive multiple touch-control drive signal vt and touch sense signals vr Multiple pulses of signal).During this period, secondary gate line 26 then maintains electronegative potential always, and second switch element t2 closes, makes to share The current potential of electrode 32 is in the state of floating.
There is between two display pattern periods interregnum (blanking period), the control mode touch mode period can be located at sky During white, and and the display pattern period have the transition period as between interval, within the transition period, secondary gate line 26 by High potential switches to electronegative potential, and second switch element t2 closes the state making the current potential of common electrode 32 be in floating, data wire 24 do not operate during this period.
By way of above, when the present invention can be in quick condition using common electrode 32 current potential, by data wire 24 To pixel electrode 31 discharge and recharge, to sense position of touch.It should be noted that in the embodiment of Fig. 1 to Fig. 4, in each pixel All it is configured with a second switch element t2 to control the voltage of common electrode 32.But second switch element t2 can also integrate simultaneously It is arranged on the position beyond pixel, the second switch element t2 of such as one-row pixels can be integrated into one, and is located at viewing area 21 Non- location of pixels, or neighboring area 29.If in addition, transmitting a signal to the touch-control display control circuit 28 of common electrode line 27 Possesses the ability providing common electrode line 27 current potential to be quick condition, second switch element t2 and secondary gate line 26 can also save Slightly.
The above-mentioned embedded touch control display floater of the present invention can all be located at the same side using pixel electrode 31 with common electrode 32 Fringe field formula (fringe field switching, ffs) the electrode framework, such as top pixel electric pole type (top of substrate Pixel, in upper neighbouring liquid crystal layer, common electrode is in lower adjacent films transistor for pixel electrode) framework or top common electrode The framework of formula (top com, in upper neighbouring liquid crystal layer, pixel electrode is in lower adjacent films transistor for common electrode).In top picture Under the framework of plain electric pole type, above pixel electrode 31, the shielding of no common electrode 32, can directly sense touch object.At top altogether With under the framework of electric pole type, though the shared electrode of pixel electrode 32 is covered, but common electrode 32 is to float in control mode touch mode Current potential, therefore common electrode 32 can be subject to the coupling effect of pixel electrode 31 be affected the electricity so as to voltage and pixel electrode 31 Pressure changes together simultaneously, therefore equally can sense touch object.Fig. 5 a and Fig. 5 b is respectively the present invention and uses top pixel electricity Regarding skeleton diagram in a pixel under pole formula framework and top common electrode formula framework.It can be seen that either top picture Plain electrode framework or top common electrode formula framework, both have common feature, that is, each pixel has one piece of independence Common electrode 32 so that the common electrode 32 of each pixel can maintain quick condition independent of each other, therefore can be by one Pixel is as minimum touch-control sensing unit.Further, since pixel electrode 31 and common electrode 32 are on vertical and horizontal direction The ratio overlapping with data wire 24, gate line 25, secondary gate line 26, common electrode line 27 reduces, and therefore can reduce touch-control sense Survey the coupling effect between electrode and All other routes.
Then, the embedded touch control display floater of the embodiment of the present invention scan mode under control mode touch mode is described.The present invention The scan mode of three kinds of control mode touch modes: the first scan mode, the second scan mode, the 3rd scan mode can be provided.
First scan mode is that gate line 25 scans one by one from the top of panel to lower section and (scans to grid from gate line 25-1 Polar curve 25-n).Meanwhile, during every gate line 25 is scanned, touch-control drive signal vt is by data line drive circuit 22 It is sent to pixel electrode 31 via data wire 24, and touch sense signals vr are received via data wire 24 by pixel electrode 31, with Complete to scan the action of touch point.All touch points in viewing area 21 can be scanned by this scan mode according to sequential. And each pixel is a touch-control sensing unit, therefore can carry out fine finger print identification function, for example multiple spot finger scan or Palmmprint scanning etc..However, this scan mode needs longer sweep time, so being relatively suitably applied the start of touch-control product Picture, or the period of display particular image；Interior during this period, when the panel driving display time is all converted to touch-control scanning Between.
Second scan mode is that viewing area 21 is divided on such as column direction (column) multiple regions (example in advance As being divided into 20th～30 area), the number of the gate line 25 in each area is simultaneously unrestricted, can be the number of one or more, then right Gate line 25 in selected region carries out touch-control scanning in proper order one by one.Because touch-control sensing is only carried out in selected region, Therefore sweep time is short compared with the first scan mode, and remains as in selected region and scan one by one, therefore in selected region Inside equally can carry out finger print identification function.And above-mentioned selected region can be determined in advance, when entering finger print identification function, Make to show specific square in picture to inform the region of user fingerprints identification.Or be, first with rough scan mode (such as The 3rd described scan mode afterwards) find out the position that touch point is located, then by the region at this position place as selected region To be scanned one by one.
3rd scan mode is equally that on such as column direction (column), viewing area 21 is divided into multiple areas in advance Domain (is for example divided into 20th～30 area), but when a region carries out touch-control sensing, the whole gate lines 25 in this region are same Time is scanned.Specifically it is assumed that there being 100 gate lines 25 in a region, when this region carries out touch-control sensing, This hundred gate lines 25 can be opened in region all of first switch element t1 to carry out touch-control sensing simultaneously.Fig. 7 is to use 3rd scan mode of the present invention carries out the schematic diagram of touch-control sensing.As shown in fig. 7, f represents the scope of finger touch it is assumed that showing Show from top to bottom be divided in region 21 sub-region a1, a2, a3 ..., each sub-region a1, a2, a3 ... sequentially enter from top to bottom Row touch-control sensing.When region a3 carries out touch-control sensing sensing, the presence of touch control object will be sensed.Now due to sub-region a3 Interior gate line 25 is to be all turned on, therefore one effective touch-control sensing unit, as shown in the enlarged drawing of Fig. 6 right, can divide Be not dotted line be framed scope sj, sj+1, sj+2.Touch-control sensing unit sj is to be connected to data wire 24-j in the a3 of sub-region Whole pixels, in the same manner, touch-control sensing unit sj+1 is the whole pixel being connected to data wire 24-j+1 in the a3 of sub-region, touches Control sensing unit sj+2 is the whole pixel being connected to data wire 24-j+2 in the a3 of sub-region.In this scan mode, due to Effectively the area of touch-control sensing unit is larger, and the resolution of therefore touch-control sensing is relatively low, is suitably applied general touch-control work( Energy.Additionally, the touch-control sensing between regional and region, except sequentially, (by above panel, to panel, all regions are equal Open once) carry out outside touch-control sensing, also can open regional (opening random for all regions once) at random, or can Only touch-control sensing is carried out to specific region (a scanning panel fixed area).
In above-mentioned 3rd scan mode, multiple gate lines 25 and multiple data wires 24 can be opened according to sequential, to transmit tactile Control drive signal vt and reception touch sense signals vr, to reach the function of multi-point touch and multi-point scanning.
Hereinafter briefly describe, how the present invention selects above-mentioned three kinds of scan modes.Fig. 7 is the touch-control display panel of the present invention The scan mode system of selection of control mode touch mode schematic diagram.As shown in fig. 7, in step s1, touch-control display panel enters touch-control Pattern, may be selected execution finger print identification function or common touch controllable function under control mode touch mode.When system executes finger print identification function (step Rapid s2) when, the mode (step s3) of optional P-SCAN gate line 25.Then, it is confirmed whether only to carry out in specific region Identification of fingerprint (step s4), if so, then using the second scan mode, carries out P-SCAN (step s5) in specific region.If No, then using the first scan mode, whole viewing area is carried out with P-SCAN (step s6).On the other hand, when system executes During common touch controllable function (step s7), because not needing finely to sense, viewing area can be divided into multiple regions to be touched Control sensing (step s8), and use the 3rd scan mode, the whole grid when each region carries out touch-control sensing, in this region Polar curve scans (step s9) simultaneously.
By properly selecting above-mentioned three kind scan mode, the present invention not only possesses the general touch-control only needing coarse scan Function, the more standby finger print identification function needing fine scanning.
Although Fig. 4 it is stated that control mode touch mode be during display pattern stops under carrying out, and do not specify more specifically Sequential relationship.Will be described below the sequential relationship of control mode touch mode and display pattern.Fig. 8 shows control mode touch mode and the display of the present invention The sequential chart of pattern.Time according to needed for above-mentioned three kinds of scan modes and the difference of characteristic, control mode touch mode and display pattern can Just like three shown in Fig. 8 a, 8b, 8c kind collocation.It is assumed herein that display is to be driven with 60hz, then during a frame (1frame) Be equivalent to 16.6ms.In Fig. 8 a to Fig. 8 c, high level represents that this pattern starts (on), and low level represents that this pattern closes (off). First, as shown in Figure 8 a, all execute control mode touch mode during some frame, and do not enter display pattern, now control mode touch mode Above-mentioned first scan mode can be adopted.Because above-mentioned first scan mode will be scanned one by one to whole panel, therefore spend The more time.In the middle of Fig. 8 a, during just selecting a whole frame, to execute control mode touch mode.In other embodiments, this scanning Mode required time, can be the frame time of one or more.Then, as shown in Figure 8 b, control mode touch mode can be during each frame Interior interregnum is carried out.Due to can have the interregnum not driving viewing area between each frame, therefore control mode touch mode can To carry out during this section.Now control mode touch mode can adopt above-mentioned second scan mode or the 3rd scan mode, to one or many Individual above region carries out scanning one by one or the synchronous scanning in this region.In addition, as shown in Figure 8 c, display pattern and control mode touch mode All subregion execution.When viewing area for example shown in Fig. 7 by top be down divided into sub-region a1, a2, a3 ... when, show mould Formula start sub-region a1 is scanned, after the completion of control mode touch mode start, sub-region a1 is scanned.Then, display pattern Restart and region a2 be scanned, after the completion of control mode touch mode start, sub-region a2 is scanned, the rest may be inferred, until whole Till individual viewing area all completes the driving of a display pattern and the driving of control mode touch mode.Now control mode touch mode can adopt above-mentioned One or more above regions are carried out the scanning one by one in this region or sweep simultaneously by the second scan mode or the 3rd scan mode Retouch.
Then, illustrate to execute the specific embodiment of the grid circuit of above-mentioned three kinds of touch-control scan modes.Fig. 9 is this The schematic diagram of the gate driver circuit of invention.Figure 11 is the basic circuit diagram of the gate driver circuit 23 of the present invention.As Fig. 9 Shown, gate driver circuit 23 have multiple gate lines drive block gop1, gop2 ... (Fig. 9 only shows two for convenience of explanation Individual gate line drives block gop1, gop2).Each gate line drives block, for example: gate line drives block gop1 to have example As the gate line driver element u1 of k cascade arrangement, u2 ..., uk, for drive such as k bar gate line 25-1,25-2 ..., 25-k.Each gate line driver element, can have basic circuit frame as shown in Figure 10 taking gate line driver element u1 as a example Structure, at least has trigger input d, clock signal input terminal ck and outfan o.Trigger input d can input The signal that the outfan o of the gate line driver element of one-level is exported, however, the triggering of the gate line driver element u1 of the first order Signal input part d, can input trigger stv via line trigger signal l2.Clock signal input terminal ck can input clock signal. Outfan o can export scanning signal to gate line 25-1.
In the middle of embodiments of the invention, it is provided with three kinds of switches sw1, sw2, sw3 in the middle of gate driver circuit 23, mat This is reaching aforesaid three kinds of touch-control scan modes.Switch sw1 is arranged on adjacent gate line and drives between block, with gate line As a example driving block gop1 and gop2, one end of switch sw1 is connected to the grid that gate line drives afterbody in block gop1 The outfan o of line driver element uk, the other end connects the gate line driver element that a gate line drives the first order in block gop2 The trigger input d of uk+1.The purpose of switch sw1, is that control gate polar curve drives block gop2, if be connected at grid Line drives after driving block gop1, or both are to drive independently of each other.Switch sw2 is connected to the trigger of an outside Line and each gate line drive between the trigger input of block first order gate line driver element.Taking Fig. 9 as a example, switch Line trigger signal l3 outside sw2 connection drives the triggering of the gate line driver element uk+1 of the block gop2 first order with gate line Signal input part d.First gate line driver element gop1 does not need to do the switching of trigger, therefore can open without setting Close sw2.The trigger input d of the gate line driver element u1 of the gate line driver element gop1 first order may be coupled directly to Article one, line trigger signal l2.It should be noted that in order that each gate line drives block can independently drive, each gate line Drive block can be respectively coupled to different line trigger signals.In addition, in each gate line driver element, having a switch sw3 even Contact signalling input d and clock signal input terminal ck, and all of switch sw3 can unify to be controlled by signal line l1 System.Switch sw3 be used for control gate polar curve drive block in, all gate line driver elements be one by one output scanning signal or with Step output scanning signal.
When control mode touch mode will adopt the first scan mode, scan one by one to do the gate line of whole viewing area.Meeting Sw1 will be switched open, each gate line driving element block, after the gate line of previous stage drives Reginal-block scanning operation, will continue It is scanned, now switch sw2 and sw3 closes.Three switch operation make gate line drive block in gate line be by Bar scans.Therefore, gate line will from viewing area first scan the last item.
When control mode touch mode will adopt the second scan mode, scan one by one to carry out subregion, switch sw1 closes and makes each grid Polar curve drives block to be mutually independent.Switch sw2 opens, and makes each gate line drive block reception triggering letter independently Number.Switch sw3 closes, and making each gate line drive the gate line in block is to scan one by one.
When control mode touch mode will adopt the second scan mode, scan one by one to carry out subregion, switch sw1 closes and makes each grid Polar curve drives block to be mutually independent.Switch sw2 opens, and makes each gate line drive the trigger of block reception independence. Switch sw3 closes, and making each gate line drive the gate line in block is to scan one by one.Because each gate line drives block institute The trigger receiving can control respectively, therefore can select the gate line only driving specific gate line to drive in block.
When control mode touch mode will adopt the 3rd scan mode, scan to carry out the full gate line of subregion, switch sw1 closes simultaneously Each gate line is made to drive block to be mutually independent.Switch sw2 opens, and makes each gate line drive touching of block reception independence Signal.Switch sw3 also opens, and makes each gate line drive the whole gate lines in block to export scanning signal simultaneously.Equally Ground, because each gate line drives the trigger that block is received can control respectively, therefore can select only to drive specifically Gate line drives the gate line in block.
It is brilliant for the thin film of active layers by above-mentioned switch is arranged on non-crystalline silicon or polysilicon or oxide semiconductor In the gate driver circuit of body pipe, can positively realize three kinds of scan modes under control mode touch mode for the present invention.
Finally, illustrate the present invention data wire output touching signals also can do simultaneously or subregion output.Figure 11 is to show this The summary Organization Chart of the data wire subregion output circuit of invention.The circuit of Figure 11 can be formed on panel, positioned at such as the application Position between the viewing area 21 of Fig. 1 and data drive circuit 22.As shown in figure 12, multiple adjacent data wires can be divided into One group, for example each group has 3 adjacent data wires.There are in each group three switches, one end of each switch is connected to One data line, the common pin being connected to data drive circuit of the other end.And the control terminal of these three switches can divide It is not connected to three control signal wires.Taking the 1st group as a example, have three data line 24-1,24-2,24-3 and three be connected to Switch sw4, sw5, sw6 of this three data line.The other end of these three switches sw4, sw5, sw6 is common to be connected to data-driven One pin ic pin1 of circuit (data drive circuit 22 of such as Fig. 1), and the control of these three switches sw4, sw5, sw6 Terminal is connected respectively to three control signal wires m1, m2, m3.Similarly, the 2nd group of configuration is identical with the 1st group, but three are opened Close common another pin ic pin2 being connected to data drive circuit of the other end of sw4, sw5, sw6.
By above-mentioned framework, three kinds of modes mainly can be taken to carry out the touch-control drive signal vt of output data line.The first Be control signal wire m1, m2, m3 simultaneously by whole switch opens, and data drive circuit pin pin1, ic pin 2, ic Pin3 sends touch-control drive signal vt simultaneously；Afterwards, then by data wire, data drive circuit via pin pin1, ic pin 2, Ic pin3, receives touch sense signals vr.
Second is that control signal wire at least one of m1, m2, m3 open switch, and remaining control signal wire closes make and break Close, and each pin ic pin1, ic pin 2, ic pin3 send touch-control drive signal vt simultaneously.Thereby so that each group Specific data wire output touch-control drive signal vt.For example, the switch sw4 of each group is opened by control signal wire m1, control signal Switch sw5, sw6 of each group are closed by line m2 and m3, and each pin ic pin1, ic pin 2, ic pin3 send touch-control simultaneously Drive signal vt.So, data wire 24-1,24-4,24-7 can be allowed simultaneously to send and to touch driving survey signal vt；Afterwards, then by Data wire, via pin1, ic pin 2, ic pin3, data drive circuit receives touch sense signals vr and is back to.
The third be control signal wire m1, m2, m3 simultaneously by whole switch opens, by the pin ic of data drive circuit Pin1, ic pin 2, ic pin3 are determining when will go out to export the data wire which touch-control driving data vt organized to；Afterwards, then By data wire, via selected pin pin, data drive circuit receives touch sense signals vr.
According to each above-mentioned embodiment, the present invention proposes In-cell touch display panel and its driving of control mode touch mode Method, can reduce the coupled capacitor between touch-control sensing electrode and All other routes, and can meet touch controllable function and fingerprint is distinguished simultaneously Know function, and be not required to extra cabling, to transmit common electrode, touch-control drive signal and touch sense signals.
