Example Embodiment

[0010] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0011] See figure 2 , figure 2 It is a schematic diagram of a method for repairing line defects of a liquid crystal display device of the present invention. The repair method in an embodiment of the present invention includes the following steps.

[0012] A liquid crystal display device 20 is provided. The liquid crystal display device 20 includes a plurality of data lines and a first repair line 23 and a second repair line 24. The first repair line 23 and the second repair line 24 and the data lines are distributed on different conductive layers The data lines include a first data line 210 with a line defect 22 and a good second data line 211. The first data line 210 and the second data line 211 respectively correspond to adjacent sub-pixels of the same color. The fir...

Abstract

The invention relates to a repairing method of line defect of a liquid crystal display device. The liquid crystal display device comprises a first data line containing the line defect and a normal second data line, the first data line and the second line are respectively corresponding to adjacent homochromatic sub-pixels, and the first data line is broken into a first section and a second section. The repairing method comprises the steps of: welding respectively at the first repairing point and the first conducting point; breaking the first repairing line at the outside of the segment consisting of the first repairing point and the first conducting point; welding respectively at the second repairing point and the second conducting point; and breaking the second repairing line at the outside of the segment consisting of the second repairing point and the second conducting point. The method of the invention can reduce the rejection rate of liquid crystal display panel.

Description

technical field [0001] The present invention relates to a method for repairing line defects of a liquid crystal display device, in particular to a method for repairing line defects that is not limited by the number of repair lines. Background technique [0002] Currently, liquid crystal display devices have been widely used in various electronic products. A general liquid crystal display device includes a thin film transistor array substrate, a color filter substrate and a liquid crystal layer sandwiched between two polar plates. A large number of scan lines, data lines and pixel units defined by the scan lines and data lines are arranged on the thin film transistor array substrate. These densely arranged scan lines or data lines are often disconnected, causing signals to fail to transmit normally, thereby forming line defects. For this, in the prior art, a rescue line is designed around the display area of ​​the liquid crystal panel. See figure 1 , figure 1 It is a sch...
