Embodiment Construction

[0030] figure 1 It is a structural schematic diagram of an existing display panel. Such as figure 1 As shown, the display panel has a first display area 150 for displaying, and a first crack detection line 160 for detecting whether there is a crack in the screen is generally arranged around the first display area 150, and the two ends of the first crack detection line 160 are A test pin 161 is provided for inputting a corresponding test signal into the first crack detection line 160 through the test pin 161 .

[0031] For example, usually by measuring figure 1 The resistance between the two test pins 161 shown in to determine whether there is a crack in the screen; if there is no crack, the resistance of the crack detection line 160 (that is, between the two test pins 161) can be several thousand ohms , if there is a crack, the crack detection line 160 is broken, and its resistance may be hundreds of megaohms. To determine whether there is a crack in the screen by measurin...

Abstract

The invention provides a display panel. The display panel comprises a substrate and crack detection lines, the substrate comprises a display area and a non-display area located around the display area, the display area comprises a plurality of pixel rows, and each pixel row is composed of a plurality of pixels; the crack detection lines are used for detecting cracks of the display panel, one endsof the crack detection lines are connected to the pixel line driving circuits, and the other ends of the crack detection lines are connected to at least one pixel line.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel. Background technique [0002] With the development and maturity of display technology, portable devices including display panels and other terminal devices are becoming popular. [0003] Generally speaking, during the process of manufacturing, transporting, and assembling the display panel, the film layer of the screen is prone to cracks, which may lead to breakage or micro-breakage of the signal lines of the screen, thereby making the screen function abnormal. [0004] Therefore, how to effectively detect screen cracks has become a research focus. Contents of the invention [0005] To solve the problems mentioned above, the present invention provides a display panel. [0006] The display panel provided by the present invention includes: [0007] a substrate, including a display area and a non-display area around the display area, the display area i...
