Abstract

The invention discloses a display panel, a display device and a crack detection method of the display panel, the display panel comprises a display area and a second frame area located on one side of the display area, the display area comprises a plurality of detection display unit groups, and each detection display unit group comprises a plurality of sub-pixels; the second frame area comprises a plurality of chamfering areas; the display panel comprises at least two first crack detection lines and a plurality of detection units, at least one first crack detection line penetrates through one or two chamfering areas, and different first crack detection lines penetrate through different chamfering areas; one end, penetrating through one chamfering area, of the first crack detection line is electrically connected with one detection display unit group through the detection unit, and under the control of the detection unit, a first detection signal transmitted by the first crack detection line in the chamfering area is provided for the detection display unit group; according to the display results of the detection display unit groups, whether cracks exist in the chamfered areas through which the first crack detection line passes is determined, and different chamfered areas correspond to different detection display unit groups.

Description

technical field [0001] This article relates to, but is not limited to, display technology, especially to a display panel, a display device, and a crack detection method for a display panel. Background technique [0002] For some electronic products, such as electronic wearable products, due to the need to provide related electronic signals to the display panel, it is necessary to set up a wiring area connecting the display panel and the electronic signal provider, which is commonly known as the "watch neck". During preparation, multiple areas on the "neck" need to be chamfered, which may cause cracks in these areas and affect the quality of the product. In some technologies, the existence of cracks in the chamfering area can only be roughly detected, and the specific location of the cracks needs to be determined by manual microscopy. The test results obtained in this way are not accurate, labor-intensive, and microscopic inspection may cause damage to the product. SUMMARY...
