Abstract

The embodiment of the invention discloses a restoration method and restoration system of a display base plate, the display base plate and a display panel. The method comprises the steps of after it is detected that open circuit or short circuit occurs at a signal line of the display base plate, forming a restoration line at the open position where the open circuit occurs or the open position formed when the short circuit signal line is restored; at least forming a protection layer on the restoration line. According to the restoration method of the display base plate, after the restoration line is formed at the open position of the signal line, further, the protection layer needs to be formed to protect the restoration line, the influence on the restoration line by technologies of washing, coating and the like of a rear section is eliminated, the restoration line is prevented from shedding to cause failure of restoration, and accordingly the restoration effect and product quality are improved.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a repair method for a display substrate, a repair system, a display substrate and a display panel. Background technique

[0002] In the production process of the display substrate, the open circuit and short circuit of the signal line seriously reduce the product yield, so the repair of the signal line is very important to improve the product yield.

[0003] When repairing, for the defect of open circuit, the repair technology can be used to deposit a conductive film layer at the disconnection to form a repair line to connect the disconnection; for the defect of short circuit between the signal lines, it is necessary to use laser to create a gap between the signal lines. The short-circuit conductive particles are removed, and at the same time, the signal line will also be disconnected by the laser at the short-circuit position. It is necessary to deposit a conductive film layer ...
