As shown in fig. 1, fig. 1 is a schematic structural diagram of a display panel provided in the prior art. In the prior art, when a display panel corresponding to a Trigate architecture is formed, the display panel includes a scan line 301 and a data line 302, where the scan line 301 and the data line 302 are disposed in a crossing manner in a display area, such as in a vertical and horizontal direction, so that the scan line 301 and the data line 302 cross to form a plurality of different areas, and each area corresponds to one sub-pixel. For example, the first subpixel 101, the second subpixel 102, and the third subpixel 103, in order to ensure that each of the different subpixels works normally, the display panel further includes a common electrode 200 when the display panel is disposed. Specifically, the common electrode 200 may be disposed on one side of the color film substrate of the display panel, so as to control voltages in the sub-pixels with different colors through the common electrode 200, and ensure normal operation of the panel.

In the prior art, when the common electrode 200 is set, because the thicknesses of the color resistance layers corresponding to different sub-pixels are different, the corresponding voltage values will also have differences, and the common electrode 200 is directly set in the display area, the corresponding voltage values in different areas are the same, so that the common voltage values corresponding to the sub-pixels in different areas cannot be differentially regulated, and the problems of crosstalk and afterimage of the panel are caused.

In this embodiment of the application, a display panel and a display device are provided, so as to effectively adjust sub-pixels with different colors in different areas, and avoid the problems of crosstalk and afterimage of the panel during display.

Specifically, in the display area of the display panel, the display area includes a plurality of pixel units disposed in different pixel areas, and each pixel unit may include sub-pixels with different colors, such as a first sub-pixel 101, a second sub-pixel 102, and a third sub-pixel 103, which are sequentially disposed from top to bottom. In the following embodiments, the first sub-pixel 101 is a red sub-pixel, the second sub-pixel 102 is a green sub-pixel, and the third sub-pixel 103 is a blue sub-pixel. Thereby realizing the display effect of different colors.

Meanwhile, for the architecture of multi-domain pixel (pixel), each pixel region further includes a main pixel and a sub-pixel. Wherein the main pixel and the sub-pixel share the same common electrode 200 (i.e., color film com, CF com). Such as the upper common electrode 200 of the display panel. In this embodiment, when the common electrode 200 is set, the common electrodes 200 corresponding to the sub-pixels with different colors are insulated from each other, and different signals can be provided respectively, so that the optimal common voltages corresponding to the pixel regions with different colors are ensured to be the same, and the problem of residual shadows is avoided.

Specifically, the common electrode 200 includes a plurality of branch electrodes 25, such as a first branch electrode 251, a second branch electrode 252, and a third branch electrode 253, when disposed. Specifically, the first branch electrode 251 is correspondingly disposed in the red sub-pixel corresponding region, the second branch electrode 252 is correspondingly disposed in the green sub-pixel corresponding region, and the third branch electrode 253 is correspondingly disposed in the blue sub-pixel corresponding region.

In this embodiment of the present application, the different branch electrodes above the sub-pixels with different colors are disconnected, that is, the branch electrodes corresponding to the sub-pixels with different colors may respectively and independently provide control signals and are mutually and independently. Therefore, different branch electrodes can respectively provide different control signals for corresponding sub-pixels, so that the voltage and the capacitance between different pixel areas of the sub-pixels are controlled, the whole display panel is ensured to have the same control effect, and the problems of crosstalk and afterimage are avoided.

In the case of disposing the common electrode 200 in the embodiment of the present application, the entire surface of the common electrode 200 is disposed at a corresponding position above the pixel unit, thereby forming a one-surface electrode. Specifically, when the common electrode 200 is disposed, the first direction and the second direction intersect each other in the first direction X and the second direction Y of the display panel. Specifically, the horizontal direction is the first direction X, the vertical direction is the second direction Y, in the first direction, the color resistances at different positions are set to be the same color resistances, the common electrode is continuously and uninterruptedly arranged, and in the second direction, the branch electrodes are arranged at intervals, so that one-side electrode structure is formed. Meanwhile, in the first direction, the colors of adjacent color resistors are the same, such as red sub-pixels in a first row, and in the second direction, the colors of adjacent color resistors are different, so that each surface branch electrode corresponding to the surface electrode can simultaneously control a plurality of areas with the same color, thereby improving the structure of the display panel and improving the performance of the display panel.

Fig. 3 is a schematic diagram of a film structure of the display panel according to the embodiment of the present application. In connection with the structure in fig. 2, in the embodiment of the present application, when the structure of the display panel is provided, the display panel includes the array substrate 30 and the color film substrate 33 that are oppositely provided. The display panel in the embodiment of the present application is exemplified by COA (color filter on array) type products. In this embodiment, the array substrate is configured as a thin film transistor array substrate, and fig. 3 illustrates the array substrate. A plurality of thin film transistor devices are arranged in the array substrate, control signals are provided for different pixel units through the thin film transistor devices, and normal operation of the panel is ensured.

Specifically, in the setting, a plurality of color resists 501 of different colors and a plurality of sub-pixel electrodes 400 are disposed on one side of the array substrate 30. In the following embodiments, the color resistor 501 is exemplified by a first color resistor 511, a second color resistor 512, and a third color resistor 513. Specifically, the first color resistor 511 may be a red color resistor disposed in the red pixel region and corresponding to the red sub-pixel, the second color resistor 512 may be a green color resistor disposed in the green pixel region and corresponding to the green sub-pixel, and the third color resistor 513 may be a blue color resistor disposed in the blue pixel region and corresponding to the blue sub-pixel. In this embodiment of the present application, the first color, the second color, and the third color are merely examples, and the first color, the second color, and the third color may be respectively given different colors according to the needs, which is not limited herein.

Specifically, the thicknesses of the film layers of the first color resistor 511 and the second color resistor 512 are set to be the same, and meanwhile, the thickness of the film layer of the third color resistor 513 is greater than that of the film layers of the first color and the second color resistor, so as to ensure the light emitting effect in the different color areas.

In this embodiment, an overlapping area 701 is further included between two adjacent color resists of different colors. In the overlapping region 701, two different color resistors partially overlap, for example, a first color resistor 511 and a second color resistor 512 overlap in the overlapping region 701, and in this region, the second color resistor 512 is disposed above the first color resistor 511.

Meanwhile, in the case of disposing the above-described sub-pixel electrodes 400, the sub-pixel electrodes 400 are disposed on the color resistors 501, and each sub-pixel electrode 400 corresponds to a different color of color resistor. In the following embodiment, the sub-pixel electrode 400 includes a first sub-pixel electrode 411, a second sub-pixel electrode 412, and a third sub-pixel electrode 413. Each sub-pixel electrode is correspondingly arranged on the color resistor, and a space exists between the sub-pixel electrodes on the color resistors with different colors.

In this embodiment, when setting the sub-pixel electrodes on the color resistors of different colors, the length and the width of the sub-pixel electrodes can be set according to the requirements of different products, which is not described here again.

Further, the color film substrate 33 further includes a common electrode 200, and the common electrode 200 is disposed on a side of the color film substrate 33 facing the array substrate 30. In the embodiment of the present application, the common electrode 200 is configured as a plane electrode, and the common electrode 200 is independent from each other in pixel regions of different colors.

Specifically, the common electrode 200 includes a plurality of branch electrodes, each of which is disposed on a color resistor of a different color, such as a first branch electrode 251, a second branch electrode 252, and a third branch electrode 253.

The first branch electrode 251, the first color resistor 511, and the first sub-pixel electrode 411 are all disposed in the same pixel region, such as a red pixel region; the second branch electrode 252, the second color resistor 512, and the second subpixel electrode 412 are correspondingly disposed in the same pixel region, such as a green pixel region, while the third branch electrode 253, the third color resistor 513, and the third subpixel 413 are correspondingly disposed in the same pixel region, such as a blue pixel region.

Meanwhile, in the embodiment of the application, the distance between the common electrode and the sub-pixel electrode on the color resistors with different colors is different. Specifically, the distance between the first branch electrode 251 and the first sub-pixel electrode 411 is D1, the distance between the second branch electrode 252 and the second sub-pixel electrode 412 is D2, and the distance between the third branch electrode 253 and the third sub-pixel electrode 413 is D3, in this embodiment, the above distances: d1 =d2 > D3.

Further, since the signals on the different branch electrodes are independent of each other, the first branch electrode has the first voltage V1, the second branch electrode has the second voltage V2, and the third branch electrode has the third voltage V3. Since the signals corresponding to the branch electrodes are independent of each other, the first voltage V1, the second voltage V2, and the third voltage V3 can be set to different driving voltage values.

Further, a second capacitor is arranged between each branch electrode and the corresponding sub-pixel electrode. Specifically, a capacitance is formed between the first branch electrode 251 and the first sub-pixel electrode 411, the capacitance is Clc-R, a capacitance is formed between the second branch electrode 252 and the second sub-pixel electrode 412, the capacitance is Clc-G, and another capacitance is formed between the third branch electrode 253 and the third sub-pixel electrode 413, the capacitance is Clc-B.

In this embodiment, since the common electrode 200 has different voltage values on the corresponding branch electrodes, and the branch electrodes are independent of each other, different control signals and voltage signals can be prepared. In this way, the difference between the capacitance Clc-R, the capacitance Clc-G and the capacitance Clc-B in the second capacitance is caused by adjusting the voltage values on the different branch electrodes. And the difference corresponds to the different distances. Thereby ensuring the mutual corresponding relation between the common electrode and each sub-pixel electrode and ensuring the regulation and control effect thereof.

Optionally, when the voltages on the different branch electrodes of the common electrode are regulated, the corresponding voltage values on the two different branch electrodes may be the same in the first branch electrode 251, the second branch electrode 252 and the third branch electrode 253. The first voltage value on the first branch electrode 251 is the same as the second voltage value on the second branch electrode 252 and is different from the third voltage value on the third branch electrode 253. Therefore, the display panel can be arranged in a layout according to actual practical requirements, three paths of different branch electrodes are equivalent to a two-path structure, or the distances between the branch electrodes and the sub-pixel electrodes are regulated and controlled according to the requirements, the voltages on different branch electrodes are set to be the same voltage, and then a plurality of branch electrodes arranged at intervals are equivalent to a one-path structure. So as to meet the use requirement, effectively improve the capacitance difference inside the panel and ensure the display effect.

Further, in the embodiment of the present application, a metal layer is further included in the array substrate, for example, the metal layer is configured as the gate layer 60. The gate layer 60 is disposed on a side close to the color film substrate. And the grid electrode layer is correspondingly arranged between two adjacent color resistances with different colors. For example, the gate layer 60 is disposed in the overlapping region 701 of the color resistor, and the length of the gate layer 60 may be greater than the length of the overlapping region 701. Meanwhile, the gate layer 60 may partially overlap the sub-pixel electrodes at both sides. Or the length of each gate layer 60 is set according to the requirements of different products, which will not be described here.

Since the gate layer 60 and the sub-pixel electrodes 400 are metal electrodes, the gate layer 60 and the sub-pixel electrodes 400 can form lateral first capacitances in different pixel regions, respectively, as shown in fig. 3, the lateral capacitances formed between the gate layer 60 and the sub-pixel electrodes are the first capacitances C1, C2 and C3, respectively.

In this embodiment, the capacitors C1, C2, and C3 are different due to different thicknesses of color resistances of different colors. In this embodiment of the present application, the voltage value corresponding to each of the branch electrodes is adjusted, so that the corresponding first capacitance value is smaller than or equal to the second capacitance value. If the first capacitor C1 is the same as the capacitor Clc-R, the common voltage value corresponding to the color resistances of different colors in the actual working process is effectively ensured to be the same as the voltage of the optimal common voltage best Vcom, so that the problems of crosstalk and afterimage easily occur when each sub-pixel of the display panel works are effectively reduced.

Further, the display panel further comprises a liquid crystal layer, and the liquid crystal layer is arranged on one side of the common electrode far away from the color film substrate and forms the display panel provided in the embodiment of the application.

Further, as shown in the following table 1, table 1 is a comparison table of each voltage measurement between the corresponding display panel and the conventional display panel in the embodiment of the present application.

In the conventional panel and the panel provided in the embodiments of the present application, each film layer is the same except for the structure of the corresponding common electrode, so as to achieve the effectiveness of comparison. And will not be described in detail here.

As can be seen from the above table, the closer the optimal common voltage Best Vcom of the pixel is to the set value of the common voltage CF com on the common electrode in the actual operation process, the better the panel display effect and performance are. For a panel of conventional design, there is a difference between the capacitance values of the first capacitances of the R/G pixel and the B pixel and the Best Vcom, one value is a%, the other value is (a+b)%, and CF com can only be set to one value, for example, E, which is between C and c+d, so that in the actual process, CF com of each pixel is caused to not correspond to the Best Vcom of the pixel, thereby forming an afterimage problem.

After the optimization, that is, in the embodiment of the application, since each branch electrode of the corresponding common electrode on the R/G/B pixel can be adjusted independently, after the adjustment, the voltage of the common electrode CF com can be the same as the Best common voltage Best Vcom value of the corresponding pixel. Therefore, the difference between different voltages is reduced, and the problems of crosstalk and afterimage of the display panel are avoided.

Further, in this embodiment of the present application, the common electrode may be configured to be 3 paths, as shown in fig. 2, and optionally, the common electrode may be configured to be two paths to save cost, which is referred to the above configuration that the common electrode is configured to be two paths, so that the common electrode is configured according to the requirements of different products, which is not described herein again.

Further, in the embodiment of the application, a display device is further provided, and the display device includes the display panel provided in the embodiment of the application. When the display panel is arranged, signals on the branch electrodes corresponding to different sub-pixels in the display panel can be independently controlled, so that the voltage corresponding to the common electrode in the actual working process is effectively ensured to be the same as the optimal common voltage value of each sub-pixel, and the problems of crosstalk and afterimage of the display panel are avoided. The comprehensive performance and quality of the panel are effectively improved.

In summary, the display panel and the display device provided by the embodiments of the present invention have been described in detail, and specific examples are applied to illustrate the principles and the embodiments of the present invention, and the description of the above embodiments is only for helping to understand the technical solution and the core idea of the present invention; although the present invention has been described with reference to the preferred embodiments, it should be understood that the invention is not limited to the particular embodiments described, but can be modified and altered by persons skilled in the art without departing from the spirit and scope of the invention.
