Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] In the following description, for the purpose of illustration rather than limitation, explanatory schematic diagrams of many technical features are given so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known structures are omitted so as not to obscure the description of the invention with unnecessary detail.

[0027] The first embodiment of the present invention provides an array substrate, including: a base layer; pixel circuits arranged on the base layer in a matrix; signal lines arranged on the base layer in a row or colum...

Abstract

The invention belongs to the field of display technology, and discloses an array substrate and a display device. The array substrate includes a base layer, pixel circuits and signal lines. The pixel circuits are arranged on the base layer in a matrix arrangement, and the signal lines are arranged on the base layer in a row or column direction. On the base layer, pixel circuits are coupled, and at least two signal lines in the same direction are respectively arranged on the outermost sides of the pixel circuits arranged in the matrix. The present invention arranges at least two signal lines in the same direction on the outermost side relative to the pixel circuits arranged in a matrix, so that the electrostatic discharge charges at at least two ends of the display panel can be derived through the signal lines, effectively reducing the risk of electrical failure. Probability, improve product yield.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a display device. Background technique [0002] The inventors of the present application unexpectedly discovered a technical problem that has not been discovered in the prior art, that is, due to the complex manufacturing process of low-temperature polysilicon devices, it is easier to cause electrostatic discharge (Electro-Static discharge, ESD static electricity) in the low-temperature polysilicon display panel during the manufacturing process. There is a large amount of charge accumulation, which causes the gate and polysilicon layer at the edge of the panel to be damaged, which in turn causes a short circuit between the gate and the polysilicon layer, and the gate signal is input to the polysilicon layer, causing electrical failure. [0003] figure 1 shows a schematic diagram of the structure of the array substrate 100 in the prior art, the arr...
