Abstract

The invention provides a display panel, a manufacturing method thereof and a display device. The display panel comprises a display area and a non-display area surrounding the display area; the displayarea comprises a plurality of data lines; the non-display area comprises detection switches in one-to-one correspondence with the at least one data line, and a crack detection line and an electrostatic discharge circuit that surround the display area; a crack detection point is arranged on the crack detection line; the crack detection line comprises a first end part and a second end part; the first end part is electrically connected with the electrostatic discharge circuit, the second end part is electrically connected with a detection signal input end of the crack detection point, the inputend of each detection switch is electrically connected with the crack detection line, and the output end of each detection switch is electrically connected with the corresponding data line. The display panel is used for achieving electrostatic protection of screen crack detection and improving the display quality of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof and a display device. Background technique [0002] During production or transportation, due to collision or extrusion, the edges of the flexible display are prone to cracks. In the subsequent use process, even small cracks will spread due to the bending or folding of the display panel, which will cause the signal line to be disconnected or the resistance to increase, which will affect the display effect. [0003] At present, for flexible display panels, screen crack detection (Panel Crack Detect, PCD) metal wires are often used to detect whether there is a break at the edge of the screen. , green pixel) is connected to one end of the thin film transistor, and the other end is connected to the detection signal input end. If there is a crack on the edge of the screen, a specific black screen bright line will appear, and the flexibl...
