Problems solved by technology

[0003] However, due to the high density of the gate driving region 102, it is difficult to repair, especially the high integration of the GOA signal line, so when the process is abnormal, the gate driving region 102 is prone to defects, thereby reducing the product yield , and cannot be tested and repaired in the subsequent manufacturing process, and can only be scrapped, which increases the production cost

Abstract

The invention provides a display panel repairing method, display panel, and device. The method comprises the following steps of: removing first portions, wherein the first substrate comprises at leastone first portion corresponding to an outer region of the first sealant region, and the outer region of the first sealant region is away from the display region; removing the protective layer and repairing the gate driving region; and forming a flat layer on the repaired gate driving region. The display panel repairing method, display panel, and device of the present invention can improve productyield and reduce production cost.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a repair method for a display panel, a display panel and a device. 【Background technique】 [0002] Such as figure 1 and 2 As shown, the existing display panel includes an upper substrate 20 and a lower substrate 10. The lower substrate 10 has a display area 101. In order to reduce the frame size of the display panel, a gate drive area (GOA (Gate On Array) is usually set on the lower substrate 10. ) 102, the gate driving region 102 includes a gate driving circuit and signal lines. [0003] However, due to the high density of the gate drive region 102, it is difficult to repair, especially the high integration of the GOA signal line, so when the process is abnormal, the gate drive region 102 is prone to defects, thereby reducing the product yield , and cannot be tested and repaired in the subsequent manufacturing process, and can only be scrapped, which increases the producti...
