Background
Currently, the performance requirements of the market for liquid crystal displays are toward high contrast (high contrastratio), no gray scale inversion (no gray scale inversion), small color shift (little colorshift), high brightness (high luminance), high color richness, high color saturation, fast response, and wide viewing angle. Current technologies capable of achieving wide viewing angle requirements include, for example, twisted Nematic (TN) plus wide viewing angle (wide viewing film), in-plane switching (IPS) lcd, fringe field switching (fringe field switching) lcd, and multi-domain vertical alignment (MVA) tft lcd.
For the conventional multi-domain vertical alignment type lcd, since alignment protrusions (alignment protrusions) or slits (slots) disposed on the color filter substrate or the tft array substrate can make the liquid crystal molecules arranged in multiple directions to obtain a plurality of different alignment domains (domains), the multi-domain vertical alignment type lcd can achieve the requirement of wide viewing angle. In the prior art, a pixel structure used in a multi-domain vertical alignment type liquid crystal display is prone to color fading (color fading), and in order to solve the color fading problem, the alignment area in the pixel structure is usually increased, for example, four alignment areas are increased to eight alignment areas.

Referring to fig. 1 to 3, the pixel structure 300 includes a data line 310, a scan line 320, a switching element 330, a first electrode layer 100 and a second electrode layer 200.
The scan lines 310 and the data lines 320 are perpendicular to each other, the data lines 310 and the scan lines 320 are enclosed with each other to form a pixel region 340, and the pixel region 340 is arranged on the display panel in a matrix form; the switching element 330 is electrically connected to the data line 300 and the scan line 320.
In an embodiment, the data line 310, the scan line 320 and the switching element 330 may be disposed on a first substrate or a second substrate of the display panel. The data line 310 extends in a horizontal direction, and the data line 310 extends in a vertical direction.

The first electrode layer 100 is disposed on the first substrate of the display panel, and includes a first sheet electrode 110 and a first stripe electrode 120; the first strip electrode 120 includes at least two first strip structures 121, widths of any two adjacent first strip structures 121 are different from each other, and a first slit 122 is formed between each two adjacent first strip structures 121; the area where the first sheet-like electrode 110 is located is a first area 131, and the areas where all the first strip-like electrodes 120 and all the first slits 122 are located are second areas 132.
The second electrode layer 200 is disposed on a second substrate opposite to the first substrate, and includes a second sheet electrode 210 and a second strip electrode 220; the second strip electrode 220 includes at least two second strip structures 221, widths of any two adjacent second strip structures 221 are different from each other, and a second slit 222 is formed between each two adjacent second strip structures 221; the area where the second sheet electrode 210 is located is a third area 232, and the area where all the second strip electrodes 220 and all the second slits 222 are located is a fourth area 231.
The second region 132 is disposed opposite to the fourth region 231 and has an equal area, and the first region 131 is disposed opposite to the third region 232 and has an equal area; the areas of the first electrode layer and the second electrode layer are smaller than or equal to the area of the pixel region.
In an embodiment of the present invention, the display panel includes, but is not limited to, a liquid crystal display panel (Liquid Crystal Display, LCD), a plasma display panel PDP (Plasma Display Panel), and a curved panel. The liquid crystal panel comprises a thin Film transistor liquid crystal display panel (Thin Film Transistor-Liquid Crystal display, TFT-LCD), a TN panel (twist dNEmaterial+film), a VA panel (Vertical Alignment), an IPS panel (In Plane Switching), an COA (ColorFilter onArray) panel and the like.
Wherein the display panel is a liquid crystal panel (Liquid Crystal Display, LCD). The first substrate is an ARRAY substrate (ARRAY), and the second substrate is a color filter substrate (CF) arranged opposite to the first substrate. Or the first substrate is a color filter film substrate (CF), and the second substrate is an ARRAY substrate (ARRAY) arranged opposite to the first substrate. If the first substrate is an ARRAY substrate (ARRAY), the second substrate is a color filter substrate (CF) disposed opposite to the first substrate, the first electrode layer 100 disposed on the first substrate is used as a pixel electrode in the pixel structure 300, and the second electrode layer 200 disposed on the second substrate is used as a common electrode in the pixel structure 300. A voltage difference may be formed between the first electrode layer 100 and the second electrode layer 200 to drive liquid crystal molecules in the display panel.
In a specific implementation, the area sizes of the second region 132 and the fourth region 231 can be adjusted according to the actual production and debugging result, so as to obtain a better area ratio for improving the color washout problem of the display panel. For example, the area ratio of the second region 132 to the fourth region 231 is 1:1, i.e. the second region 132 is disposed opposite to the fourth region 231 and has the same area. Correspondingly, the area ratio of the first region 131 to the third region 232 is also 1:1, i.e. the first region 131 and the third region 232 are disposed opposite to each other and have the same area. In particular, the first region 131 has the same area as the second region 132. The third region 232 has the same area as the fourth region 231.
In some embodiments, the area ratio of the second region 132 to the fourth region 231 may be 1:2, correspondingly, the area ratio of the first region 131 to the third region 232 is 2:1. the area ratio of the second region 132 to the fourth region 231 is not limited in the embodiment of the present invention.
In some embodiments, the first electrode layer 100 and the second electrode layer 200 may be made of a transparent conductive material such as indium tin oxide, indium zinc oxide, or the like. The light transmittance of the materials such as indium tin oxide and indium zinc oxide can greatly improve the aperture ratio of the pixel structure 300, thereby improving the transmittance of the display panel. The material of the first electrode layer 100 and the second electrode layer 200 is not limited in the present invention.
In some embodiments, the first electrode layer 100 and the second electrode layer 200 are respectively disposed on two opposite substrates, and the two substrates overlap each other and are located in the pixel region 340.
In some embodiments, the first stripe-shaped structure 121 and the second stripe-shaped structure 221 each extend at least two extension angles. For example, the first stripe-shaped structures 121 and the second stripe-shaped structures 221 each extend at four extension angles including 45 °, 135 °, 225 °, and 315 °. The extending angle is the size of the included angle between the first stripe 121 and the second stripe 221 and the scan line 320.
In some embodiments, the pixel region 340 includes at least two pixel sub-regions, the number of pixel sub-regions being equal to the number of extension angles; the extension angle of the first stripe structure 121 in the same pixel sub-region is equal to the extension angle of the second stripe structure 221. For example, assuming that the extension angle includes four angles of 45 °, 135 °, 225 °, and 315 °, the pixel region 340 may be divided into four pixel sub-regions. When the first substrate and the second substrate form a voltage difference, the long axes of the liquid crystal molecules can tilt 45 degrees, 135 degrees, 45 degrees and 135 degrees relative to the horizontal direction respectively through different pixel subareas formed by the strip structures with different extension angles.
In some embodiments, the width of the first stripe 121 is greater than 50% of the width of the first slit 122 adjacent to the first stripe 121.
Specifically, the first stripe structures 121 and the first slits 122 are disposed at intervals on the first electrode layer 100. Each first stripe 121 has at least one first slit 122 adjacent thereto. For example, if the width of the first stripe 121 is 4 micrometers and the number of the first slits 122 adjacent to the first stripe 121 is two, the width of any one of the first slits 122 adjacent to the first stripe 121 is less than 8 micrometers. In particular, the width of the first stripe 121 is 1.25 times the width of the first slit 122 adjacent to the first stripe 121. Similarly, the width of the second stripe 221 is greater than 50% of the width of the second slit 222 adjacent to the second stripe 221. By implementing the embodiment of the present invention, it is possible to prevent the occurrence of a decrease in the steering sensitivity of the liquid crystal molecules interposed between the first electrode layer 100 and the second electrode layer 200 due to an excessively high width of the first slit 122 or the second slit 222.
In some embodiments, the width of the first stripe structure 121 or the second stripe structure 221 of the same pixel sub-region gradually decreases from the middle toward the edge.
Specifically, the widths of the first stripe structures 121 or the second stripe structures 221 of the same pixel sub-region are arranged according to a preset arrangement order. For example, the width of the first stripe structure 121 or the second stripe structure 221 of the same pixel sub-region gradually becomes smaller from the middle toward the edge. In particular, the widths of any two adjacent first stripe structures 121 of the same pixel subregion are not equal to each other. In other embodiments, the width of the first stripe structure 121 or the second stripe structure 221 of the same pixel sub-region gradually decreases in the counterclockwise direction; or the width of the first stripe structure 121 or the second stripe structure 221 of the same pixel sub-region becomes gradually larger in the counterclockwise direction. The embodiment of the present invention does not limit the preset arrangement sequence corresponding to the first stripe structure 121 or the second stripe structure 221 of the same pixel sub-region.
In some embodiments, the width of the first slit 122 or the second slit 222 of the same pixel sub-region gradually decreases from the middle toward the edge.
Specifically, the widths of the first slits 122 or the second slits 222 of the same pixel sub-region are arranged according to a preset arrangement order. For example, the width of the first slit 122 or the second slit 222 of the same pixel sub-region gradually becomes smaller from the middle toward the edges. In particular, the widths of any two adjacent first slits 122 of the same pixel sub-region are not equal to each other. In other embodiments, the width of the first slit 122 or the second slit 222 of the same pixel sub-region is gradually reduced in the counterclockwise direction; or the width of the first slit 122 or the second slit 222 of the same pixel sub-region becomes gradually larger in the counterclockwise direction. The embodiment of the present invention does not limit the preset arrangement sequence corresponding to the first slit 122 or the second slit 222 in the same pixel sub-region.
According to the embodiment of the invention, the electrode layers with the strip-shaped structures are respectively arranged on the first substrate and the second substrate in the display panel, so that the arrangement direction of liquid crystal molecules in the display panel is controlled, and a plurality of different alignment fields are obtained, so that the wide viewing angle effect of the display panel is realized.
