Thin film transistor array base plate and patching method thereof

Abstract

A thin film transistor array base plate comprises a base plate, multiple scanning lines, multiple data lines, multiple thin film transistors and multiple picture element electrodes and a fixing circuit. The scanning assigning lines and data assigning lines are located on base plate to divide multiple picture element areas with thin film transistor in each and are driven by relevant scanning assigning lines and data lines. The picture element electrode is separately in each picture element area and is electrically connected with relevant thin film transistor. This invention also provides a fixing method for thin film transistor array base plate, which is mainly to connect fixing circuit with breakage points of flaw-scanning assigning line to fix the flaws into two-point flaw and one-point flaw and even no flaw.

Description

technical field [0001] The present invention relates to a thin-film transistor array substrate (TFT array substrate) and its repair method, and in particular to a repair method for broken lines of scan lines or common lines. A repaired thin film transistor array substrate 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 the display is concerned, the cathode ray tube (Cathode Ray Tube, CRT) has been monopolizing the display market in recent years because of its excellent display quality and economical efficiency. However, for the environment where individuals operate most terminals / display devices on the table, or from the perspective of environmental protection, if the trend of energy saving is predicted, cathode ray tubes still have many problems in terms of space utilization and energy consumption, and There is no effective sol...

AI Technical Summary

Problems solved by technology

[0004] It should be noted that the above thin film transistor array substrate may face the problem of line defects, and the problem of line defects is usually caused by the breakage of the wiring (scanning wiring or common wiring) on ​​the substrate.

When the scanning wiring on the substrate is broken, the pixel electrode connected to the broken part of the scanning wiring will not be displayed, and the storage capacitor formed at the broken part of the scanning wiring will not be displayed normally. And then cause the thin film transistor array substrate to be scrapped
