Abstract

The invention provides a display device, a display panel and a detection method thereof, and relates to the technical field of display. The display panel comprises a display module, the display moduleis provided with a display area and a peripheral area surrounding the display area, the display area is provided with sub-pixels capable of being closed in response to detection signals, and the sub-pixels comprise the first sub-pixels and the second sub-pixels; The peripheral area comprises a first area, a second area and a third area, and the first area comprises a wiring area and a binding area. A first detection line comprises a first section, a second section and a first bent section, the first section and the second section are arranged in the wiring area, and the first bent section extends into the second area; the second detection line comprises a third section, a fourth section and a second bent section, the third section and the fourth section are arranged in the wiring area, the second bent section extends into the third area, and the second section is connected with the third section through a connecting line; a first switching element is connected with the second sectionand the first sub-pixel and is used for responding to the control signal to be conducted; and a second switching element is connected with the fourth section and the second sub-pixel and is used for responding to the control signal to be conducted.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display device, a display panel, and a detection method for a display panel. Background technique [0002] During the manufacturing process of the display panel, it is easy to produce small cracks in the edge area, which are difficult to detect. Among them, the cracks mainly come from laser cutting and other processes. These cracks may extend to the display area, thereby affecting the normal operation of the display panel. Therefore, in order to improve product yield, it is necessary to detect cracks in the display panel. At present, it is generally determined whether there is a crack in the detection circuit through a detection circuit coiled around the edge of the display panel, by detecting a resistor or using sub-pixels for bright line detection, so as to determine whether there is a crack in the display panel. However, the detection accuracy of the existing...
