A double grid line array substrate, test method, display panel and display device

Abstract

A double-gate line array substrate is disclosed, wherein, in any pair of double-gate lines and two sets of adjacent double-gate lines and two adjacent data lines within two pixel pairs within the defined area, each pixel pair The pixel units are respectively connected to the same data line in the two adjacent data lines, and the adjacent two pixel units in the two pixel pairs in the extending direction of the data lines are respectively connected to different data lines in the two adjacent data lines; In two adjacent pixel pairs in the extension direction of any set of double gate lines, the data lines connected to the two pixel units in one pixel pair are different from the data lines connected to the two pixel units in the other pixel pair but Adjacent; two adjacent pixel units in the extension direction of the data line are respectively connected to the gate lines that are different from their respective adjacent transmission scanning signals, and the two adjacent pixel units in the extension direction of any set of double gate lines are respectively connected to their respective Adjacent gate lines that transmit different scanning signals. The double grid line array substrate can improve the detection rate of pixels.

Description

technical field [0001] Embodiments of the present disclosure relate to the display field, and more specifically, to a double grid line array substrate, a testing method, a display panel and a display device. Background technique [0002] Generally speaking, display devices can be classified into cathode ray tube display CRT, plasma display PDP, liquid crystal display LCD, light emitting diode LED display, active light emitting diode OLED display, etc. according to different manufacturing materials, for example. At present, flat panel displays such as LCD and LED displays have gradually replaced traditional displays such as CRT, are widely used in various industries, and become an indispensable component of most electronic devices. [0003] In displays such as LCD and LED displays, an array substrate is a major component. In the array substrate, pixel units are arranged periodically. Each pixel unit may include a thin film transistor (TFT) and a pixel electrode, and each pi...

AI Technical Summary

Problems solved by technology

[0006] However, in the array test (Array Test) of the double-grid line array substrate, the existing double-grid line array substrate often leads to the problem of low pixel detection rate, resulting in low product quality control, which in turn leads to an increase in related costs

For example, pixel defects caused by indium tin oxide (ITO) residues are a phenomenon encountered in the production process of double grid line array substrates

However, in the array test of the prior art dual grid line array substrate, in some cases, it may not be possible to detect the defective pixel caused by the residual conductive material.
