Abstract

The invention provides a display panel and a crack detection method thereof and a display device. The display panel comprises a first insulation structure layer, a first crack detection line, a secondinsulation structure layer and a second crack detection line which are sequentially arranged on a substrate, the first crack detection line and the second crack detection line are both located in theperipheral area and arranged around the display area. One end of the first crack detection line is configured to receive a detection signal, the other end is configured to output a first output signal, one end of the second crack detection line is configured to receive the detection signal, and the other end is configured to output a second output signal. According to the display panel, whether cracks are generated in the positions where the first crack detection line and the second crack detection line are located or not can be judged according to the first output signal and the second output signal, independent detection of the cracks is achieved, accurate positioning of the cracks in the product production and related bad analysis process is facilitated, and the productivity and the product performance are improved.

Description

Technical field [0001] The present disclosure relates to the field of display technology, in particular to a display panel, a crack detection method thereof, and a display device. Background technique [0002] With the development of display devices, Organic Light-emitted Diode (OLED) display technology has shown great potential. The excellent display performance of OLED makes it have a wide range of application space, but the development of technology has put forward higher requirements for the integration of the screen. The flexible multi-layer integrated integrated touch (Flexible Multi-Layer On Cell, FMLOC) technology has integrated the screen Integration with touch control has greatly improved the integration of display devices, and FMLOC technology has become a development trend in the display industry. [0003] Panel Crack Detection (PCD) technology has been widely used in display panel detection. For display panels using FMLOC technology, the existing crack detection tech...
