Abstract

The invention relates to a repair wire system applied to a liquid crystal display panel and a method thereof, wherein the liquid crystal display panel comprises a data driver, the data driver comprises a plurality of data channels, and the data channels are provided with a plurality of corresponding data lines. The repair method of the liquid crystal display panel has the following steps: at least one data channel and the corresponding data line are used as at least one repair wire for data transmission; when at least one broken signal wire is required to be repaired, the data of the broken signal wire is transmitted to the at least one data channel and the corresponding data line of the data driver.

Description

technical field [0001] The invention provides a repair line system for a liquid crystal display panel, in particular to a repair line system for repairing a broken circuit of a signal line of a liquid crystal display panel, thereby improving the pass rate of the liquid crystal display panel. Background technique [0002] Please refer to FIG. 1 for a schematic diagram of a conventional liquid crystal display panel. A liquid crystal display panel 100 includes: a substrate 12 , an X-board (X-board) 14 , a Y-board (Y-board) 16 and a flexible printed circuit board (FPC) 29 . Wherein, the flexible printed circuit board is used to connect the X circuit board 14 and the Y circuit board 16, and the X circuit board 14 and the Y circuit board 16 are used to output signals to the substrate 12, so that the liquid crystal display panel 100 Display screen. In addition, the liquid crystal display panel 100 further includes a plurality of tape carrier packages (TCP) 18 for electrically con...
