Disconnection repair method

Abstract

The invention provides a broken wire repair method. The broken wire repair method includes the steps that an array substrate is provided, wherein broken wires are placed on the array substrate, and first insulating layers cover the wires; first via holes and second via holes are respectively formed in the first insulating layers at both ends of the breaking positions of the wires, and the first via holes and the second via holes respectively expose the side edges of the wires below the first via holes and the second via holes; repair wires are formed, one ends of the repair wires are connectedto one ends of the breaking positions of the wires through the first via holes, and the other ends of the repair wires are connected to the other ends of the breaking positions of the wires through the second via holes. By forming the first via holes and the second via holes on the side edges of the broken wires, there is no need to climb over the first insulating layers in the climbing process of the repair wires, so that the climbing height of the repair wires is reduced, the repair difficulty of the broken wires is reduced, and the success rate of repair of the broken wires is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for repairing broken wires. Background technique [0002] With the development of display technology, liquid crystal display (Liquid Crystal Display, LCD) and organic light emitting diode display (Organic Light Emitting Display, OLED) and other flat display devices have high image quality, power saving, thin body and wide application range, etc. Advantages, and are widely used in various consumer electronics products such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, desktop computers, etc., and become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between ...

Problems solved by technology

like figure 1 and figure 2 As shown, the existing disconnection repair method is: respectively open two via holes 4' on the insulating layer 3' at both ends of the fracture 2', and the two via holes 4' respectively expose the fracture 2' The broken line 1' at both ends of the broken line is then formed to repair the line 5', and the repaired line 5' connects the broken line 1' at both ends of the broken part 2' through two via holes 4', so that the broken line 1' is repaired, wherein, now In the prior art, the via hole 4' is usually formed in the center of the broken line 1'. When the repair line 5' is formed, the repair line 5' needs to climb over the edge of the broken line 1', and the climbing height is too high , causing the repair line 5' to be easily broken at the edge of the broken line 1', resulting in poor repair
