Display panel

Abstract

The invention provides a display panel. The display panel includes an array substrate, a common voltage bus, an array substrate test set line and a connection line; the array substrate includes a functional area and a test area disposed outside the functional area; the common voltage bus is disposed in the functional area for providing a common voltage; the array substrate test set line is disposed in the test area adjacent to the common voltage bus, and the array substrate test set line includes a common voltage test line for providing a common voltage test signal for the common voltage bus and testing the common voltage bus; the connection line is used for connecting traces disposed in the functional area and the test area, and at least one portion of the connection line, common voltagetest line and common voltage bus is located on the same metal layer. Compared with the prior art, the display panel can effectively reduce the occurrence of the ESD phenomenon.

Description

technical field [0001] The invention relates to the field of display panels, in particular to a display panel capable of preventing ESD. Background technique [0002] A thin-film transistor liquid crystal display (Thin-Film Transistor Liquid Crystal Display, TFT-LCD) is a kind of display, which has the advantages of low power consumption, thinness, and high resolution. With the development of science and technology, the manufacturing technology of the display panel of the thin film transistor display has gradually matured, and the application range of the thin film transistor display panel in the market is becoming more and more extensive. [0003] However, in the production process of thin film transistor display panels, electrostatic discharge (electro static discharge, ESD) often causes damage to the internal circuits of thin film transistor display panels, thereby affecting the yield of thin film transistor display panels, so more and more industry players pay attention ...

[0003] However, in the production process of thin film transistor display panels, electrostatic discharge (electro static discharge, ESD) often causes damage to the internal circuits of thin film transistor display panels, thereby affecting the yield of thin film transistor display panels, so more and more industry players pay attention Prevention of Electrostatic Discharge

[0004] A display panel in the related art includes an array substrate, a common voltage bus set on the surface of the array substrate, and array substrate test line, the common voltage bus is used to provide a common voltage, and the array substrate test line is used to test the The common voltage bus provides a common voltage test signal for testing, because the array substrate test group line needs to transmit a test signal to the common voltage bus, so a jumper is used between the common voltage bus and the array substrate test group line connection, resulting in the occurrence of ESD at the cross-line position
