AI Technical Summary

Problems solved by technology

An effective method is to directly increase the thickness of the trace copper (Cu), but due to technical limitations, the thickness of Cu cannot be increased indefinitely. When the Cu thickness exceeds 1000nm, Cu disconnection and uneven thickness will occur. problems that seriously affect the normal function of the panel
In addition, high-end panels urgently need to reduce the RC loading to maintain their normal display. Therefore, it is a severe challenge for high-end products to reasonably reduce the RC loading of the panel.

Abstract

The invention provides a GOA drive circuit and an array substrate. According to the display panel, the resistance wire arranged on the anode layer and the metal wire arranged on the first metal layerare connected in parallel to form the clock signal wire, so that the resistance of the clock signal wire is reduced under the condition that the film layer structure is not changed, the resistance-capacitance load of the bus area is reduced, and normal display of the display panel is maintained.

Description

technical field [0001] The present application belongs to the technical field of display panels, and in particular relates to a GOA driving circuit and an array substrate. Background technique [0002] Gate Driver On Array, referred to as GOA, is to use the Array process in the existing thin-film transistor liquid crystal display to manufacture the gate (Gate) line scan drive signal circuit on the Array substrate to realize the drive mode of gate progressive scan. [0003] As the size of the panel becomes larger and the resolution becomes higher and higher, the response speed of the display is required to be faster and faster. In such a background environment, it is necessary to effectively reduce the resistance-capacitance load (RC loading) of the wiring. An effective method is to directly increase the thickness of the trace copper (Cu), but due to technical limitations, the thickness of Cu cannot be increased indefinitely. When the Cu thickness exceeds 1000nm, Cu disconne...
