Problems solved by technology

In other words, in order to accurately form the contact window exposing the second line segment, it is necessary to repeatedly modulate (modulate) to obtain the appropriate laser beam energy and conditions, which will greatly increase the time required for the process
In addition, if the conductive adhesive is only electrically connected to one contact window of the two wire segments, the resistance formed by it will be relatively large.

Abstract

The invention provides a display device. The display device comprises a display panel and a conductive adhesive, wherein the display panel is provided with a plurality of leads and a dielectric layer covering the leads; at least one of the leads has a broken wire defect; the dielectric layer is provided with at least three repair contact windows positioned opposite to the broken wire defect; the lead with the broken wire defect is exposed by at least part of the repair contact windows; and the conductive adhesive is arranged at the position of the broken wire defect and is electrically connected with the lead with the broken wire defect through the repair contact windows. The invention also provides a repairing method suitable for the display device.

Description

【Technical field】 [0001] The present invention relates to an electronic device and a repairing method for the electronic device, and in particular to a display device and the repairing method for the display device. 【Background technique】 [0002] As far as displays are concerned, thin film transistor liquid crystal display panels (Thin film transistor liquid crystal display panels, referred to as TFT-LCD panels) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have gradually become the market's preferred mainstream. [0003] Generally speaking, a thin film transistor liquid crystal display panel mainly has a display area, a wire bonding area, and a plurality of wires connecting the display area and the wire bonding area. lead bonding, OLB). Generally speaking, if the lines in the outer lead bonding (OLB) are scratched, it will usually cause abnormal product images or line defects, which wi...
