Problems solved by technology

[0003] In the actual production process, stresses such as cutting cause tiny cracks to easily occur on the edge of the display panel
We know that flexible display uses organic light-emitting diode technology. Water and oxygen will have a destructive chemical reaction for organic light-emitting diodes. The existence of cracks provides a way for water and oxygen, which eventually leads to dark spots in the light-emitting area, and even A series of problems such as material failure and life reduction

Abstract

The invention discloses a display substrate, and a crack detection method thereof and a display device, and the display substrate comprises a substrate which comprises: a display area and a frame area surrounding the display area; a grid driving circuit which is located in the frame area; a test terminal which is located in the frame area adjacent to the gate drive circuit; and a crack detection line which is arranged around the gate drive circuit in the frame area. One end of the crack detection line is electrically connected with the test terminal, and the other end is electrically connected with a power line for providing a voltage signal for the gate drive circuit.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a crack detection method thereof, and a display device. Background technique [0002] Organic electroluminescent (OLED) display devices are display screens based on organic electroluminescent diodes. It has excellent characteristics such as self-illumination, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide operating temperature range, simple structure and manufacturing process, and has attracted more and more attention. Its application prospects broad. [0003] In the actual production process, stresses such as cutting cause tiny cracks to easily occur on the edges of the display panel. We know that flexible display uses organic light-emitting diode technology. Water and oxygen will have a destructive chemical reaction for organic light-emitting diodes. A series of problems such as material fai...
