Array substrate, manufacturing method thereof, and display device

Abstract

The present invention provides an array substrate, comprising: a substrate; a first signal line and a second signal line arranged on the substrate, the first signal line and the second signal line are arranged on the same layer and spaced from each other an insulating layer covering the first signal line and the second signal line; a groove penetrating the insulating layer is formed on the insulating layer, and the groove extends to the first signal line and the second signal line; The bottom surface of the layer where the two signal lines are located separates the first signal line from the second signal line, so that the first signal line and the second signal line are insulated. Correspondingly, the present invention also provides a method for manufacturing an array substrate and a display device. The present invention can reduce grid defects.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] The touch display panel includes an external touch display panel and an in-cell touch display panel. The in-cell touch display panel is widely used because of its high light transmittance and thin thickness. The in-cell touch display panel can be divided into a mutual capacitive structure and a self capacitive structure. Among them, the self-capacitance structure includes a plurality of block-shaped touch electrodes, and each touch electrode is connected to the drive circuit through a touch signal line, and the drive circuit receives the signal change through each touch signal line and each touch control The coordinate position of the electrode determines the touch position. [0003] figure 1 It is a schematic structural diagram of an array substrate in a convention...

AI Technical Summary

Problems solved by technology

Affected by foreign matter such as dust, it is easy to cause not only the data line 14 and the parallel signal line 12 to be formed in the patterning process, but also the conductive residual part 15 between the data line 14 and the parallel signal line 12 is likely to be generated, which will lead to data Short circuit between line 14 and parallel signal line 12

Since the touch electrode 13 is multiplexed as a common electrode in the display phase, that is, the parallel signal line 12 is loaded with a common voltage signal in the display phase, therefore, when the data line 14 and the parallel signal line 12 are short-circuited, the voltage on the data line 14 It will be pulled down to the common voltage on the parallel signal line 12, so that during the display process, the data line 14 cannot provide the required data voltage for the sub-pixels, and then the sub-pixels cannot be displayed normally, resulting in poor grid
