Abstract

The invention discloses a display panel, a display panel driving method and a display device. The display panel is provided with a light-transmitting area and a display area at least partially surrounding the light-transmitting area. The display panel comprises: a substrate; a touch electrode layer arranged on one side of the substrate, wherein the touch electrode layer comprises a plurality of touch electrode blocks; and a plurality of touch control signal lines, wherein the touch control signal lines and the touch control electrode blocks are electrically connected in a one-to-one mode, at least one touch control signal line in the multiple touch control signal lines is multiplexed as a first crack detection line, and at least part of the first crack detection line is arranged around the light-transmitting area. According to the display panel provided by the embodiment of the invention, at least one touch signal line is multiplexed as the first crack detection line, and a passing area of the first crack detection line does not need to be reserved between adjacent touch electrode blocks, so that the coverage area of the touch electrode blocks is increased, the formation of a touch blind area is avoided, and the touch performance of the display panel is improved.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a display panel, a display panel driving method and a display device. Background technique [0002] In order to achieve a larger screen-to-body ratio, some display panels use in-screen hole-digging technology, that is, a hole-digging area for placing front-facing cameras and other hardware is set in the effective display area. For the display panel with integrated touch function, since the hole position is designed with a crack detection line for detecting whether the edge of the hole is broken or not caused by hole cutting, however, due to the limitation of wiring, the existing crack detection line will affect the touch performance. cause adverse effects. [0003] Therefore, there is an urgent need for a new display panel, a method for driving the display panel, and a display device. Contents of the invention [0004] Embodiments of the present invent...
