Embodiment Construction

[0065] image 3 A top view of a thin film transistor array substrate according to a preferred embodiment of the present invention is shown. Please refer to image 3 , the thin film transistor array substrate 200a of this embodiment has a plurality of sub-pixel regions 210, which include a plurality of first-time pixel regions 212 with an area of ​​S1 and a plurality of second sub-pixel regions 214 with an area of ​​S2, and each sub-pixel A TFT 220a / 220b is disposed in the region 212 / 214 respectively. Each thin film transistor 220a / 220b includes a gate 222a / 222b, a channel layer 224a / 224b, a source 226a / 226b and a drain 228a / 228b. Wherein, the channel layer 224a / 224b is disposed on the gate 222a / 22b, and the source 226a / 226b and the drain 228a / 228b are disposed on the channel layer 224a / 224b above the gate 222a / 222b. In addition, there is an overlapping region 240a / 240b between the drain 228a / 228b and the gate 222a / 222b, so that the drain 228a / 228b, the channel layer 224a / 22...

Abstract

A thin-film transistor array substrate, with a plurality of secondary pixel zones, and all secondary pixel zones are respectively arranged with a thin-film transistor, which consists of one grid, one channel layer, one source and one drain. In which, the channel layer is arranged between the source, drain and the grid. Moreover, there is an overlap area between the drain and grid to ensure the drain, channel layer and grid form a grid-drian parasitic capacitor. The thin-film transistor array substrate is characterized in that the secondary pixel zone has a plurality of the first secondary pixel zone with the area of S1 and a plurality of the second secondary pixel zones with the area of S2, and S1>S2. Moreover, the overlap area in the first secondary pixel zone is A1, and that of the second secondary pixel zone is A2, and 1<A1 / A2 is less than or equal to S1 / S2.

Description

technical field [0001] The present invention relates to a thin film transistor array substrate (thin film transistor array, TFTarray), in particular to a thin film transistor array substrate capable of improving the flicker phenomenon (flicker) of a liquid crystal display. [0002] Background technique [0003] The rapid progress of the multimedia society is mostly due to the rapid progress of semiconductor devices or display devices. As far as displays are concerned, cathode ray tubes (cathode ray tubes, CRTs) have been monopolizing the display market in recent years due to their excellent display quality and economical efficiency. However, for the environment where individuals operate multi-terminal / display devices on the table, or from the perspective of environmental protection, if the trend of energy saving is predicted, there are still many problems in the space utilization and energy consumption of cathode ray tubes, and There is no effective solution to the demands ...
