Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0033] With the gradual maturity of the display panel industry, the production line of the display panel has higher and higher requirements on the production yield of the display panel. During the manufacturing process of the display panel, the display panel is prone to cracks, which reduces the reliability of the display panel. Therefore, the production yield of the display panel can be improved through crack detection. In the prior art, conventional voltage and resistance detection methods can be used to detect ...

Abstract

The invention discloses a display panel, a driving method of the display panel and a display device. The display panel comprises a display area and a non-display area, the non-display area is providedwith at least two signal input ends, at least one control signal input end, at least two detection signal lines and detection circuits, and the display area is provided with a plurality of data lines; the control ends of the detection circuits are electrically connected with the control signal input ends in a one-to-one correspondence manner; the input end of each detection circuit is electrically connected with one signal input end through one detection signal line; the output end of each detection circuit is electrically connected with different data lines; an input signal provided by at least one signal input end provides a black picture driving signal for the display panel, and an input signal provided by at least one signal input end provides a bright picture driving signal for the display panel. The intuition of crack detection of the display panel can be improved, and the accuracy of crack detection of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display panel, a method for driving the display panel, and a display device. Background technique [0002] In the process of manufacturing the display panel, there are cracks in the display panel due to the process, which reduces the reliability of the display panel. Therefore, it is necessary to detect the cracks of the display panel. In the crack detection process of the display panel, there are problems that the detection process is complicated and cannot be applied to mass production, and the visual judgment is single, and there are problems of misjudgment and missed judgment. Contents of the invention [0003] The invention provides a display panel, a driving method of the display panel and a display device, so as to improve the accuracy of detecting cracks of the display panel and the intuitiveness of the detection result, and simultaneousl...
