Substrate, its repair method, and manufacturing method

Abstract

The invention provides a substrate and a repairing method and manufacturing method thereof. In the substrate, signal lines include a plurality of conductive connection structures arranged between body parts at the two ends and connected in parallel. Thus, when subsequent repair is needed, some conductive connection structures can be cut off in a laser cutting mode, and accordingly resistance of the corresponding signal lines is increased.

Description

technical field [0001] The invention relates to a substrate, a repair method and a manufacturing method thereof. Background technique [0002] In some display panels, multiple sets of gate driving circuits need to be set for driving. Each group of gate driving circuits is generally driven by a corresponding clock signal line. see figure 1 , is a schematic diagram of a partial structure of an array substrate in the prior art, wherein multiple sets of gate drive circuits GOA and multiple clock signal lines CLK for driving each set of GOA are provided. In order to make the multiple signals output by each group of gate driving circuits satisfy a specific timing relationship, it is generally required that the clock signals also used to drive each gate driving circuit also satisfy the corresponding timing relationship. In the process of realizing the present invention, the inventors found that due to the manufacturing process, it is difficult to accurately control the resistanc...

AI Technical Summary

Problems solved by technology

In the process of realizing the present invention, the inventors found that due to the manufacturing process, it is difficult to accurately control the resistance and capacitance of each clock signal line, resulting in that the transmission delay of the clock signal on each clock signal line cannot be accurately controlled. As a result, the timing relationship between each clock signal cannot meet the requirements, and horizontal stripes may be generated, thereby affecting the luminous display

However, once the clock signal line in the array substrate is manufactured, the resistance is difficult to adjust, and it is difficult to adjust the resistance through subsequent repairs to overcome the above defects
