Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example 1:
as shown in fig. 2 and 3, the present embodiment provides a display substrate, which is divided into a plurality of pixel units, each pixel unit including at least one color of sub-pixel a; in the present embodiment, the description is given by taking an example that each pixel unit includes three color sub-pixels a of a red sub-pixel, a blue sub-pixel, and a green sub-pixel, but it should be understood that each pixel unit is not limited to include the above three different color sub-pixels a, and each pixel unit may also include other color sub-pixels such as a white sub-pixel and a wine red sub-pixel, which are not listed here.
Specifically, the display substrate in this embodiment includes: a substrate 20; a fixed electrode 21 disposed above the substrate 20; a dielectric layer 23 disposed above the common electrode at a position corresponding to each sub-pixel and a support pillar 22 disposed between two adjacent dielectric layers 23; a movable electrode 24 disposed above the layer where the dielectric layer 23 and the support posts 22 are located, at a position corresponding to each sub-pixel a; and the movable electrodes 24 at the positions corresponding to the sub-pixels a are arranged at intervals; the dielectric layer 23 is used for reflecting light irradiated onto the movable electrode 24 to form light with the same color as that of the sub-pixel corresponding to the dielectric layer 23, and the thicknesses of the dielectric layers 23 reflecting light with different colors are different; a support column 22 for supporting a movable electrode 24; the movable electrode 24 and the fixed electrode 21 are used for generating a potential difference after being applied with voltage, and the movable electrode 24 controls the contact area of the medium layer 23 corresponding to each movable electrode according to the magnitude of the potential difference so as to adjust the quantity of light emitted by the sub-pixel.
Therefore, the display substrate can be directly used for displaying, and compared with the existing liquid crystal display device, the liquid crystal display device does not need structures such as a liquid crystal, a polaroid, a color filter, a backlight source and the like, so that the light efficiency is greatly improved, and the power consumption is reduced.
In order to clearly understand the operation principle of the display substrate of the present embodiment, the functions of each part of the display substrate of the present embodiment are described in detail below.
First, the function of the dielectric layer 23 will be described. The thickness of the dielectric layer 23 determines the color of the sub-pixel to which it corresponds. Specifically, as shown in fig. 1, the optical interference modulation unit includes: the device comprises a first flat plate P1, a second flat plate P2, a first aluminum film 1, a second aluminum film 2 and a spacing fixed block 3; the space fixing block 3 supports the first plate P1 and the second plate P2, and defines a space gap H. After the light is transmitted into the gap through the translucent first aluminum film 1, it is reflected from the second aluminum film 2, and then the light is reflected back and forth between the first plate P1 and the second plate P2 without any interruption, each time some light is transmitted from above. These reflections cause the light of most wavelengths to cancel each other out due to interference, but the enhancement effect is produced when the wavelength of the reflected light and the distance between the first aluminum film 1 and the second aluminum film 2 exactly conform to a specific functional relationship. That is, when the distance H between the two parallel reflective surfaces of the optical interference modulation unit is a certain value (corresponding to an F-P etalon), light of a specific wavelength is intensified and emitted from above, and light of other wavelengths cancel each other out. Therefore, the etalon functions as a mirror that reflects only one color, and the color of the reflected light can be selected by changing the distance H between the first aluminum film 1 and the second aluminum film 2. According to the above principle, the thickness of the dielectric layer 23 in the display substrate of the present invention determines the color of the reflected light.
As shown in fig. 2, the structure of the display substrate of the present embodiment includes a fixed electrode 21, a movable electrode 24 corresponding to the red sub-pixel, and a dielectric layer 23 (the thickness of the dielectric layer 23 is H)R) A movable electrode 24 corresponding to the green sub-pixel position, and a dielectric layer 23 (the thickness of the dielectric layer 23 is H)G) A movable electrode 24 corresponding to the position of the blue sub-pixel, and a dielectric layer 23 (the thickness of the dielectric layer 23 is H)B). The structure of each sub-pixel is equivalent to an etalon, and the wavelength of light reflected by the etalon can be selected by adjusting the thickness of the dielectric layer 23 of the sub-pixel. As shown in FIG. 3, the fixed electrode 21 and the movable electrode 244 of the red sub-pixel have a spacing HRTherefore, when external light irradiates the "etalon" of the red sub-pixel, the red light is intensified and reflected, and lights of other colors cancel each other out, the principle of the green sub-pixel and the blue sub-pixel is the same as that of the red sub-pixel, only the distance between the movable electrode 24 and the fixed electrode 21 is set to be different, that is, the thickness of the dielectric layer 23 is set to be different, and the size of the distance determines the wavelength and the color of the light reflected by the "etalon". When the spacing between the sub-pixels is sufficiently large,the light reflected by the sub-pixels is infrared light, when the distance between the sub-pixels is small enough, the light reflected by the sub-pixels is ultraviolet light, the wavelengths of the two lights are beyond the range recognizable by human eyes, and the pixel is in an off state, namely a black state. For example, when the movable electrodes 24 of the red, green, and blue sub-pixels are all in the original state shown in fig. 2, the movable electrodes 24 and the fixed electrodes 21 are supported by the supporting posts 22, so that the distance between the movable electrodes 24 and the fixed electrodes 21 is relatively large, and at this time, the light reflected at the positions of the red, green, and blue sub-pixels is infrared light, which is invisible to human eyes and appears as a black state. As shown in FIG. 3, the movable electrodes 24 at the red sub-pixel position are all at the original position, so the red sub-pixel is in the black state, but the movable electrodes 24 at the green sub-pixel position and the movable electrodes 24 at the blue sub-pixel position are all at the excited position, i.e. are in contact with the dielectric layer 23 after voltage is applied, and the distances between the movable electrodes 24 and the fixed electrodes 21 are HGAnd HBTherefore, the sub-pixel where the movable electrode 24 at the position of the green sub-pixel and the movable electrode 24 at the position of the blue sub-pixel are respectively reflected with green light and blue light and is represented as a bright state, and the pixel unit is represented as a superimposed color of the green light and the blue light, namely, cyan.
Next, how the gray scale of each sub-pixel on the display substrate is realized will be described. The gray scale in the display substrate in the present embodiment depends on the contact area between the movable electrode 24 and the dielectric layer 23 in the corresponding sub-pixel. The whole function of each sub-pixel of the display substrate is equivalent to a mirror which can reflect only one color, the color of the reflected light can be selected by only changing the distance H between the fixed electrode 21 and the movable electrode 24 (namely, the thickness of the dielectric layer 23), and the reflected light is stronger when the working area of the mirror is larger. As shown in fig. 3, when the interval between the fixed electrode 21 and the movable electrode 24 is fixed at HRWhen the potential difference U between the fixed electrode 21 and the movable electrode 24 is larger, the movable electrode 24 is more strongly attracted by electric charges, the elastic deformation is larger, and the movable electrode 24 and the fixed electrode 21 are fixedThe larger the contact area or length L with the dielectric layer 23 at a certain distance, the larger the effective working area of the sub-pixel, and thus the greater the intensity of the red light reflected by the sub-pixel, i.e. the brighter the sub-pixel, the different gray scale brightness is formed by changing the potential difference between the fixed electrode 21 and the movable electrode 24, and the different color is formed by the three primary colors of red, green and blue and their different gray scales. As shown in fig. 4, the length L and the brightness U are linearly related.
As shown in fig. 5, the display substrate of the present embodiment further includes: a plurality of gate lines 25 and a plurality of data lines 26 disposed on the substrate 20 and insulated from the fixed electrodes 21; the gate line 25 and the plurality of data lines 26 are arranged to intersect and define one sub-pixel a at the intersection; wherein each sub-pixel comprises a thin film transistor; the gates of the tfts in the sub-pixels in the same row are connected to the same gate line 25, the sources of the tfts in the sub-pixels in the same column are connected to the same data line 26, and the drains of the tfts in each sub-pixel a are connected to the respective movable electrodes 24. Of course, the display substrate further includes a source driver and a gate driver; the source driver is connected to the data line 26, and is configured to provide a data voltage signal to each sub-pixel a through the data line 26; the gate driver is connected to the gate line 25 for supplying a gate scanning signal to each of the sub-pixels a through the gate line 25.
Specifically, each sub-pixel a is provided with a thin film transistor, the gate of the thin film transistor is connected to the row scanning line, the source of the thin film transistor is connected to the data line 26, the drain of the thin film transistor is connected to the movable electrode 24, the movable electrode 24 is fixed at the left and right ends through a fixed supporting block, the fixed electrode 21 is plated on the glass substrate 20, and the dielectric layer 23 on the fixed electrode 21 not only maintains the fixed distance between the fixed electrode 21 and the movable electrode 24, but also prevents the short circuit between the two. An air gap is reserved between the movable electrode 24 and the dielectric layer 23, and the air gap has the function of keeping the original black state. Each row of gate lines 25 is connected to a gate driver, the data lines 26 are connected to a source driver, when the pixel array is operated, each row of gate lines 25 is sequentially opened, and the pixel array scans row by row, when a certain row is opened (i.e., all thin film transistors on the row are opened, and the sources and the drains of the thin film transistors are conducted), the source driver outputs voltage signals of all the sub-pixels a on the row, and the voltage signals are written into the movable electrode 24 through the conduction of the sources and the drains because the switches of the thin film transistors are conducted, so that different potential differences are formed between the movable electrode 24 and the fixed common electrode, and the potential differences of different sub-pixels a form different gray-scale brightness. Then, the thin film transistor in the row is turned off, the thin film transistor in the next row is turned on, and the writing of the next row signal is started to express the color and gray scale of all the sub-pixels a in the next row. It should be noted that, when a row of thin film transistors is in an on state, a signal is written, and after the signal writing is completed, the row of thin film transistors is in an off state for a relatively long period of time, the source and the drain of the thin film transistor are no longer turned on, and are in an off state, in this state, the data line 26 writes a signal to the sub-pixels a in other rows, and the voltage signal on the data line 26 changes continuously, but since the thin film transistors are in the off state, the voltage signal on the data line 26 is not written to all the sub-pixels in the row where the thin film transistors are turned off. Meanwhile, since the movable electrode 24 and the fixed electrode 21 form an overlapping area through the dielectric layer 23, they are equivalent to a variable capacitor, and the voltage between two poles of the capacitor has a holding characteristic, and the larger the capacitor is, the stronger the holding characteristic is. When the voltage writing of the sub-pixel a is completed, the potential difference between the movable electrode 24 and the fixed electrode 21 remains unchanged due to the voltage holding characteristic, and the gray-scale luminance of the sub-pixel a remains unchanged or changes very slightly (below the minimum gray-scale luminance difference).
In the present embodiment, the movable electrode 24 and the fixed electrode 21 are made of aluminum, but other materials with semi-reflective and semi-transparent properties may be adopted.
In summary, the display substrate of the present embodiment can be directly used for displaying, and compared with the existing liquid crystal display device, structures such as liquid crystal, polarizer, color filter, backlight source, etc. are not required, so that the light efficiency is greatly improved, and the power consumption is reduced.

Of course, the display panel of the present embodiment further includes a pair of cell substrates disposed opposite to the display substrate and located on the movable electrode 24 side, and the pair of cell substrates can protect the movable electrode 24.
Correspondingly, the display device in the embodiment includes the display panel. The display device may further include a front light source for providing incident light to the display panel. So that the display device can perform display under any condition.

It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
