Abstract

The invention provides a display panel, a crack detection method and a preparation method thereof, and a display device. The display panel comprises a crack detection circuit and a touch layer. The crack detection circuit is arranged in the edge area of the display panel; one end of the crack detection circuit is used for being electrically connected with a control signal end and receiving a control signal; and the other end of the crack detection circuit is electrically connected with the touch layer and is used for receiving a touch signal. According to the invention, cracks in the edge areaof the display panel can be rapidly, accurately and efficiently detected, and compared with the existing PCD wiring mode, the scheme provided by the embodiment of the invention is simpler to operate,higher in detection efficiency, smaller in occupied space and beneficial to realization of a narrow frame; an existing film layer is used for forming the crack detection circuit, and the production cost of the display panel is not increased while crack detection is achieved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a display panel, a crack detection method, a manufacturing method thereof, and a display device. Background technique [0002] For flexible OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display screens, cracks (Crack) are easily generated in the edge area. Currently, the commonly used crack detection method is to use PCD (Panel Crack Detect, panel crack detection) wiring to detect. However, the operation of this detection method is relatively complicated, the detection efficiency is low, and the space occupied by the PCD wiring is relatively large, which is not conducive to the realization of narrow borders. Contents of the invention [0003] In view of the shortcomings of the existing methods, the present application proposes a display panel and its crack detection method, preparation method and display device...
