Embodiment 1

[0034] The top view structure schematic diagram of the pixel in the TFT array substrate provided by Embodiment 1 of the present invention is as follows Figure 7 shown ( Figure 7 only shows the local structure of two adjacent pixel units), Figure 8 for Figure 7 Schematic diagram of the cross-sectional structure along the DD’, Figure 9 for Figure 7 Schematic diagram of the cross-sectional structure along EE'. From Figure 7 , 8 , 9, it can be seen that the TFT array substrate provided in Embodiment 1 includes:

[0035] a plurality of scan lines 201 (two adjacent scan lines 2011 and 2012 are shown in the figure);

[0036] A plurality of data lines 202 (three adjacent data lines 2021 , 2022 and 2023 are shown in the figure) that insulate and intersect with the plurality of scan lines 201 ;

[0037] A pixel unit located in a pixel area surrounded by adjacent scan lines and adjacent data lines (two adjacent pixel units PIX1 and PIX2 are shown in the figure).

Embodiment 2

[0052] The top view structure schematic diagram of the pixel in the TFT array substrate provided by the second embodiment of the present invention is as follows Figure 11 as shown ( Figure 11 only shows the local structure of two adjacent pixel units), Figure 12 for Figure 11 Schematic diagram of the cross-sectional structure of the middle edge FF', Figure 13 for Figure 11 Schematic diagram of the cross-sectional structure along GG' in the middle. From Figure 11 , 12 13, it can be seen that the second embodiment is similar to the first embodiment, the similarities between the two will not be repeated, and the differences between the two will be emphasized. compared to Figure 7 , 8 , Embodiment 1 shown in 9, 10, Figure 11 , 12 The difference between the second embodiment shown in 13 and 13 is that no shielding electrodes are provided above the data lines 2021 , 2022 , 2023 , that is, they are not covered by the shielding electrodes. Therefore, the common ele...

Embodiment 3

[0059] The top view structure schematic diagram of the pixel in the TFT array substrate provided by the third embodiment of the present invention is as follows Figure 14 as shown ( Figure 14 only shows the local structure of two adjacent pixel units), Figure 15 for Figure 14 Schematic diagram of the cross-sectional structure along HH', Figure 16 for Figure 7 Schematic diagram of the cross-sectional structure along II'. From Figure 14 , 15 , 16, it can be seen that the third embodiment has similarities and differences with the first and second embodiments. The main difference is that in the third embodiment, the pixel electrode is comb-shaped and includes a plurality of strip electrodes; the common electrode is sheet-shaped; the pixel electrode is located above the common electrode and is insulated from the common electrode. The TFT array substrate of the third embodiment further includes a shielding electrode, which is formed by extending the sheet-shaped common ...

Abstract

The invention discloses a TFT array substrate. The TFT array substrate comprises a plurality of scanning lines, a plurality of data lines and pixel units located in regions defined by the adjacent scanning lines and the adjacent data lines. Each pixel unit comprises a first electrode and a second electrode, wherein the first electrodes and the second electrodes are arranged in an overlapped and insulated mode. The first electrodes are respectively in the shape of a piece, and the second electrodes are strip-shaped electrodes which extend in the first direction and are arranged in the second direction. The first pixel unit and the second pixel unit which are adjacent form a unit group. The first pixel unit comprises a first part which extends in the first direction and a second part which extends from the end region of the first part to the second pixel unit. The second pixel unit comprises a third part which extends in the first direction and a fourth part which extends from the end region of the third part to the first pixel unit. The second part and the fourth part are arranged in a staggered mode. Through the design, color resistance compensation is not needed and the transmittance is increased.

Description

technical field [0001] The invention relates to the field of flat panel display, in particular to a TFT array substrate, a display panel and a display device including the TFT array substrate. Background technique [0002] Flat panel displays are popular due to their thinness, power saving and other advantages, among which liquid crystal display panels are the most common. Liquid Crystal Display Panel (Liquid Crystal Display Panel) mainly includes the following types according to its liquid crystal working mode: TN (Twisted Nematic, twisted nematic) type, IPS (In-plane Switching, plane switching) type, FFS (Fringe Field Switching , fringe field transition) type, etc. The fringe field switching liquid crystal display technology has been proved to be a good display liquid crystal mode for high resolution and wide viewing angle. Domain, this kind of design gets rid of the limit of even number of liquid crystal domains (domain) driven by horizontal electric field in IPS mode, ...
