Problems solved by technology
When the source circuit breaks in the display area of the display substrate, it can usually be repaired by laser equipment using the data line disconnection (Data Open, DO) reserved inside the display substrate to repair the circuit, but when the lead of the source circuit Partial breakage occurs in the fan out (Fan out) area, that is, when a lead open (Lead Open, LO) occurs, it cannot be repaired using the internal repair circuit of the display substrate
[0004] In the prior art, when the disconnected position of the lead circuit is located outside the liquid crystal cell, the panel pad repair (Panel Pad Repair, PPR) equipment can be used for repair, but when the disconnected position of the lead circuit is located in the part inside the liquid crystal cell , it cannot be repaired
[0005] For the breakage of the lead circuit in the liquid crystal cell, since PPR equipment cannot be used for maintenance, defective products can only be scrapped, thus reducing the repairability rate of the display substrate with lead circuit breakage

The invention discloses a repair circuit applied to a display baseplate. The display baseplate comprises a display area and a lead area disposed outside the display area. The repair circuit comprises a first repair line, a second repair line and a third repair line, wherein the first repair line is disposed on the side of the lead area remote from the display area and intersects a lead in the lead area; the second repair line is disposed on the side of the lead area close to the display area and intersects the lead in the lead area; and the third repair line connects the first repair line to the second repair line, wherein the lead in the lead area is electrically insulated from the first repair line and the second repair line. The invention also discloses the display baseplate, a display device and a repair method for the display baseplate.
Description
technical field [0001] The present invention relates to the field of display technology, in particular, the present invention relates to a repair circuit and a repair method of a display substrate, a display substrate including a repair circuit, and a display device including a display substrate. Background technique [0002] Display substrates have been widely used in various display devices. In order to meet the requirements of high resolution and / or miniaturization of various display devices, the electrode width of the internal circuit of the display substrate becomes narrower and narrower, and the possibility of defective electrode breakage of the internal circuit of the display substrate is relatively high. [0003] For a thin film transistor liquid crystal display device (TFT-LCD), the internal circuit of the display device mainly includes a gate circuit, a source circuit and a common electrode. When the source circuit breaks in the display area of the display subst...
