[0067] figure 2 It is a schematic top view of the pixel structure 1000 according to the first embodiment of the present invention. Please refer to figure 2, the pixel structure 1000 of this embodiment is suitable for being electrically connected to the scan line SL and the data DL. In this embodiment, the scan lines SL and the data lines DL are arranged alternately. In other words, the extending direction of the data lines DL is not parallel to the extending direction of the scanning lines SL. Preferably, the extending direction of the data lines DL is perpendicular to the extending direction of the scanning lines SL. The scan lines SL and the data lines DL are generally made of metal materials. However, the present invention is not limited thereto. According to other embodiments, the scan lines SL and the data lines DL may also use other conductive materials. For example: alloys, nitrides of metal materials, oxides of metal materials, oxynitrides of metal materials, or ...

[0085] Figure 7 It is a schematic top view of a pixel structure 1000A according to the second embodiment of the present invention. Please refer to Figure 7 The pixel structure 1000A of this embodiment is similar to the pixel structure 1000 of the first embodiment, and only the differences between the two will be described below, and the similarities between the two will not be repeated.

[0086] In this embodiment, each strip electrode 142 has a first end 142a and a second end 142b, each first end 142a is connected to the first main electrode part 120 or the second main electrode part 130, and the same strip electrode group 140 The second ends 142b in each are connected to each other. In more detail, each second end 142b of this embodiment has a branch 142b - 1 , and each branch 142b - 1 is respectively connected to the second end 142b of the adjacent strip electrode 142 . In this embodiment, each branch 142b - 1 can extend in a direction parallel to the data line DL, so ...

[0089] figure 1 It is a schematic diagram of the existing pixel structure. Figure 8 It is a schematic diagram of a pixel structure 1000 according to the first embodiment of the present invention. Figure 9 It is a schematic diagram of a pixel structure 1000A according to the second embodiment of the present invention. Depend on figure 1 It can be seen that in the existing pixel structure, disclination lines are likely to occur on both sides R of the pixel electrode. Compare figure 1 and Figure 8 It can be seen that the disclination line problem on both sides R of the pixel electrode of the pixel structure 1000 of the first embodiment is improved. Similarly, by Figure 9 The problem of disclination lines on both sides R of the pixel electrode of the pixel structure 1000A shown in the second embodiment is further improved.

[0090] In addition, please refer to Figure 9 and Figure 10 , in the pixel structure 1000A of the second embodiment, the shortest distance between...

Abstract

The invention relates to a pixel structure which is suitably applied for electrical connection with a scan line and a data line. The pixel structure comprises an active component and a pixel electrode. The active component is electrically connected with the scan line and the data line. The pixel electrode is electrically connected with the active component. The pixel electrode comprises a plurality of strip-shaped slit groups. Each strip-shaped slit group comprises a plurality of strip-shaped slits the extending directions of which are parallel to one another. At least parts of the strip-shaped slits are of a non-isosceles trapezoid shape. A display panel using the pixel structure in the invention is not prone to dark line defects. Therefore, the display characteristic of the display panel is optimized.

Description

technical field [0001] The present invention relates to a pixel structure, and in particular to a polymer-stable alignment (PSA) pixel structure. Background technique [0002] With the vigorous development of display technology, consumers have higher and higher requirements for display image quality. In addition to the requirements for the resolution, color saturation, and response time of the display, consumers also have requirements for the contrast ratio and transmittance of the display. The requirements are also increasing day by day. [0003] Therefore, some display manufacturers have developed a polymer stabilized alignment (PSA) display panel to improve the contrast and light transmittance of the display panel. But, if figure 1 As shown, in the existing polymer stabilized alignment display panel, disclination lines tend to occur on both sides R of the pixel electrode, which reduces the contrast and light transmittance of the display panel. Based on the above, how ...
