Abstract

The display device and crack sensing method provided by the present invention include a display area and a non-display area around the display area by using a substrate, the display area includes a plurality of sub-pixels arranged in an array; One or more crack sensing lines in the area, one end of the one or more crack sensing lines is connected to the control end of the test control switch, and the other end is connected to the test pin, and the test control switch is used to control the test signal The plurality of sub-pixels are provided so that the test control switch can be controlled according to the state of the crack sensing line to realize the sensing of whether there is a crack in the display device.

Description

technical field [0001] The present invention relates to display technology, in particular to a display device and a crack detection method. Background technique [0002] With the development of display technology and the maturity of flexible display technology, display devices including flexible display screens are gradually coming into people's lives. [0003] Generally speaking, during the process of preparation, transportation and assembly of the display device, the circuit film layer of the screen is prone to cracks, which will cause the signal line of the screen to be broken or slightly broken, and then make the screen function abnormal. [0004] Therefore, how to effectively sense the cracks in the circuit film of the screen has become a research focus. Contents of the invention [0005] Aiming at the above-mentioned problem of how to effectively detect cracks in the circuit film of the screen body, the present invention provides a display device and a crack sensing...
