Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
At present, most of liquid crystal displays are single liquid crystal screens, and the contrast is low and can only be maintained at about 1200. The double-screen display is to stick two layers of display screens (cells) together, and can improve the contrast of the liquid crystal display to over 10 thousands.
The two display screens are superposed, and since the pixel sizes of the two cells are similar, the pixel size area of the sub display screen (sub cell) is generally four times that of the main display screen (main cell). When the periods of two pixels are close to each other, moire defect is likely to occur, and in order to avoid this defect, the pixel size of the sub-panel is designed to be larger at the time of product design. The signal lines of the sub-cells and the main cells have different periods, and the moire phenomenon is improved. However, as the size of the sub-display screen pixel gradually increases, the data (data) line of the sub-cell shields the main cell pixel differently, which causes the color temperature fluctuation of the display screen pixel to be large, and finally affects the product quality.
Example one
Referring to fig. 1 to 4, fig. 1 is a structural diagram of an array substrate according to an embodiment of the present invention, and as shown in fig. 1, the embodiment provides an array substrate including: a base substrate 2; a plurality of pixel electrodes arranged in an array on the substrate base plate 2; wherein at least one of the pixel electrodes includes a first electrode portion 22 and two second electrode portions 23, the first electrode portion 22 being located between the two second electrode portions 23; the light transmittance of the first electrode part 22 is smaller than that of the second electrode part 23.
Specifically, the pixel electrode includes a first electrode portion 22 and a second electrode portion 23, and the second electrode portion 23 is closer to the signal line 21 than the first electrode portion 22, which can be understood as the second electrode portion 23 is closer to the edge portion of the pixel electrode. The light transmittance of the pixel electrode is higher as the light transmittance is closer to the edge position of the pixel electrode. That is, the light transmittance of the second electrode part 23 is greater than that of the first electrode part 22.
The signal line 21 includes a data line 211 or a scan line 212, the region of the pixel electrode can be regarded as a rectangular region, the data line 211 is distributed on a first pair of sides of the pixel electrode, and the scan line 212 is distributed on a second pair of sides of the pixel electrode. The division of the first electrode portion 22 and the second electrode portion 23 may be performed by taking a first signal line on one side of the pixel electrode as a starting point (0% position), a second signal line on the other side of the pixel electrode as an ending point (100% position), taking an electrode portion included at a position point of 20% between the first signal line and the second signal line as the second electrode portion 23, taking the second electrode portion 23 as a symmetrical structure, dividing the pixel electrode into three sub-units, taking a portion of the pixel electrode other than the second electrode portion 23 as the first electrode portion 22, i.e. the pixel electrode is divided in a ratio of 2 to 6 (wherein each second electrode portion 23 is 20% and each first electrode portion 22 is 60%), it is of course also possible to divide the pixel electrode equally, wherein the first equally divided area is the second electrode portion 23, the second equally divided area is the first electrode portion 22, and the third equally divided area is the other second electrode portion 23.
The array substrate in this embodiment includes: a base substrate 2; a plurality of pixel electrodes arranged in an array on the substrate base plate 2; wherein at least one of the pixel electrodes includes a first electrode portion 22 and two second electrode portions 23, the first electrode portion 22 being located between the two second electrode portions 23; the light transmittance of the first electrode part 22 is smaller than that of the second electrode part 23. Different electrode parts of the pixel electrode are set to have different transmittances, namely, the higher light transmittance is set at the position close to the edge of the pixel electrode, so that the problem of low light transmittance at the edge of the pixel electrode due to shielding can be solved, the color temperature fluctuation of pixels of the array substrate is reduced, and the product quality is improved.
Further, the pixel electrode is a slit electrode, and the first electrode portion 22 and the second electrode portion 23 each include a plurality of strip-shaped sub-electrodes; the slit width of the first electrode portion 22 is larger than the slit width of the second electrode portion 23.
Specifically, the array substrate includes a data line 211 and a scan line 212 on the substrate 2, a pixel electrode is disposed at a crossing area of the data line 211 and the scan line 212, the pixel electrode includes a first electrode portion 22 and two second electrode portions 23, and a distance between the first electrode portion 22 and the data line 211 is greater than a distance between the second electrode portion 23 and the data line 211. The slit width at the first electrode part 22 is larger than the slit width at the second electrode part 23, and the smaller the slit width between the pixel electrodes, the higher the light transmittance. In this way, the light transmittance of the pixel electrode of the second electrode part 23 is greater than that of the pixel electrode of the first electrode part 22, so that the second electrode part 23 has a greater light transmittance at a position close to the data line 211, the problem of low light transmittance at the edge position of the pixel electrode due to shielding can be solved, the color temperature fluctuation of the pixels of the array substrate can be reduced, and the product quality can be improved.
The slit widths between the stripe-shaped sub-electrodes in the first electrode part 22 may be the same or different, and when different, the slit width is smaller closer to the edge of the pixel electrode (i.e., closer to the data line 211 or closer to the scan line 212). Likewise, the slit widths between the stripe-shaped sub-electrodes within the second electrode part 23 may be the same or different, and when different, the slit widths are smaller closer to the edge of the pixel electrode (i.e., closer to the data line 211 or closer to the scan line 212).
Further, as shown in fig. 2, when the light transmittances of the first electrode portion 22 and the second electrode portion 23 are set, in addition to setting: besides the slit width of the first electrode part 22 being greater than the slit width of the second electrode part 23, there may be provided: the stripe-shaped sub-electrode width of the first electrode part 22 is greater than that of the second electrode part 23. The smaller the line width of the strip-shaped sub-electrode is, the higher the light transmittance is. That is, by setting the line widths of the stripe-shaped sub-electrodes located at different regions of the pixel electrode, different light transmittances can be determined. Therefore, the problem of low light transmittance at the edge position of the pixel electrode caused by shielding is solved, the color temperature fluctuation of the pixels of the array substrate is reduced, and the product quality is improved.
As shown in fig. 2, in at least one of the pixel electrodes, one of the two second electrode portions, the first electrode portion 22 and the other of the two second electrode portions are sequentially arranged along the extending direction of the scan line 212.
Further, as shown in fig. 3, in at least one of the pixel electrodes, one of the two second electrode portions, the first electrode portion, and the other of the two second electrode portions are sequentially arranged in a direction perpendicular to an extending direction of the scanning line. Different light transmittance can be determined by setting the slit width of each electrode part of the pixel electrode or the line width of the strip-shaped sub-electrode. Therefore, the problem of low light transmittance at the edge position of the pixel electrode due to shielding is solved, the color temperature fluctuation of the pixels of the array substrate is reduced, and the product quality is improved. In fig. 4, the data line 211 is a meander line. The scan lines 212 may also be routed as polylines.
Further, a gap between the pixel electrodes of the second electrode part 22 is less than or equal to 3.5 um; the gap between the pixel electrodes of the first electrode part 23 is greater than or equal to 4.5 um.
Further, the line width of the pixel electrode of the second electrode part 22 is less than or equal to 2 um; the line width of the pixel electrode of the first electrode portion 23 is greater than or equal to 2.8 um.
The embodiment of the invention also provides a display panel which comprises an opposite substrate and the array substrate in the embodiment. Different electrode parts of the pixel electrode are set to have different transmittances, namely, the higher light transmittance is set at the position close to the edge of the pixel electrode, so that the problem of low light transmittance at the edge of the pixel electrode due to shielding can be solved, the color temperature fluctuation of pixels of the array substrate is reduced, and the product quality is improved.
As shown in fig. 5, an embodiment of the present invention further provides a display device, which includes a main display panel 1 and the display panel in the foregoing embodiment, where the main display panel 1 is located on a light emitting side of the display panel.
The array substrate provided by the invention can improve the color temperature fluctuation of the pixels of the display screen, thereby improving the product quality, as shown in fig. 6, a pixel 1 is a color temperature fluctuation curve when a traditional pixel structure is adopted, and a pixel 2 is a color temperature fluctuation curve when the pixel structure provided by the invention is adopted.
Taking a 65-inch display panel as an example, the pixel size of the main display panel 1(main cell) is smaller, the size of the sub display panel (sub cell) is larger, the sub cell pixel size is larger than the main cell pixel size, and as the size increases, the deviation between the main cell and the sub cell is larger as the position of the panel is farther from the starting point, and the color temperature of the display panel is different due to the difference of the deviation distances.
The second layer of ITO (indium tin oxide) of the pixel 1 is of conventional design and the line width and gap of the second layer of ITO (i.e. the pixel electrode) of the pixel 2 at the second electrode portion 23 are 1.8 μm and 3.0 μm respectively and at the first electrode portion 22 are 2.8 μm and 5.0 μm respectively. Fig. 6 shows the simulation results, and it can be seen from the simulation results that the difference between the maximum value and the minimum value of the fluctuation of the color temperature of the product becomes smaller after the pixel 2 is adopted, the original 3000K is changed to 800K, the cycle becomes larger, and the fluctuation of the whole is obviously improved.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
