Abstract

The invention is concerned with the thin film transistor array, includes the base plate, several thin film transistor and several pixel electrode: sets the thin film transistor on the base plate respectively, which each thin film transistor consists of the grid, the semiconductor layer, the source electrode and the drain electrode; sets the grid on the base plate, which the grid is with the controlling part, the connecting part and the capacitance compensation part, the connecting part connects between the controlling part and the capacitance compensation part. There is the first overlap area between one end of the drain electrode and the controlling part of the grid that places a premium on the first parasitic capacitance. There is the second overlap area between another end of the drain electrode and the capacitance compensation part of the grid that places a premium on the second parasitic capacitance. The sum between the first parasitic capacitance and the second parasitic capacitance is the fixed value.

Description

technical field [0001] The present invention relates to a thin film transistor (thin film transistor, TFT), and in particular to a thin film transistor array capable of improving brightness uniformity of a liquid crystal display panel and a repair method thereof. Background technique [0002] 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, thin film transistor liquid crystal displays (thin film transistor liquid crystal displays, TFT-LCDs), which have superior characteristics such as high display quality, good space utilization efficiency, low power consumption, and no radiation, have gradually become the mainstream of the market. [0003] The thin film transistor liquid crystal display is mainly composed of a thin film transistor array, a color filter (color filter) and a liquid crystal layer (liquid crystal layer). figure 1 It is a schematic top view of a known ...
