Abstract

The invention provides a display panel, a crack position positioning method thereof and a display device, which relates to the technical field of display and is used for detecting whether there is a crack in the display panel or not and positioning the existence position of the crack. A display area of the display panel comprises a plurality of first data lines, and a non-display area of the display panel comprises a plurality of detection lines and a plurality of first detection switches; the plurality of detection lines are arranged along the extension direction of the first edge of the non-display area; the first edge is an edge, which is away from the display area, of the non-display area; one end of the detection line receives a detection signal, the other end of the detection line iselectrically connected with at least one first data line through at least one first detection switch, and the detection signal is used for enabling the first data line connected with the detection line to drive the connected pixel not to emit light when the detection line is not broken and enabling the first data line connected with the detection line to drive the connected pixel to emit light when the detection line is broken; and in the connected detection line and first data line, the position of the detection line and the position of the first data line are set according to a preset rule.

Description

【Technical Field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a crack position positioning method thereof, and a display device. 【Background technique】 [0002] Currently, cracks are prone to appear at the edges of the display panel. On the one hand, the occurrence of cracks is caused by cutting stress during the cutting process of the display panel. In addition, for a flexible display panel, when the flexible display panel is bent, if the radius of curvature is too small and exceeds the tolerable range of the flexible screen, cracks are likely to exist at the edges. The crack will cause the trace at the corresponding location to break. Moreover, if the crack extends from the edge of the display panel to the display area, it will also affect the traces and circuits arranged in the display area, and seriously affect the display effect of the product. [Content of the invention] [0003] In view of this, the embodim...
