Problems solved by technology
[0004] However, the protection ability of the floating silicon ring structure is limited, and the electrostatic charge cannot be exported, and the external electrostatic charge may still invade the panel from the hole-digging part, causing electrostatic discharge failure points on the panel and affecting the display effect. It may even cause irreparable damage to the panel; the frame glue on the periphery of the hole-digging area through the ground trace will cause the risk of the frame glue falling off, which will eventually affect the performance of the display panel

Embodiment Construction
[0027] 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.
[0028] As mentioned in the background art, a display panel usually includes a hole-digging area for placing and installing a camera. In the process of preparing or transporting the display panel, there will inevitably be friction, which will lead to the generation of static electricity, and the generated static electricity will easily enter the display panel from the hole-digging area of the display panel, while the existing display panel is around the hole-digging The method of arranging a floating silicon ring...

The invention discloses a driving method of a display panel, a display panel and a display device. The display panel includes a display area, a first non-display area and a second non-display area, the display area surrounds the first non-display area, and the first non-display area A through hole is provided, and the through hole runs through the display panel. The display panel also includes a plurality of display driving signal lines, and some display driving signal lines pass through the first non-display area; Some or all of the display drive signal lines output grounding signals, so that when external static electricity enters the display panel through the through hole, the static electricity is released through the display drive signal line in time to prevent display abnormalities caused by static electricity intrusion into the display panel, and prevent static electricity from invading The damage caused by the display panel to the display panel; moreover, there is no need to separately design grounding traces around the through-holes, so as to avoid the risk of the frame glue coming off when the grounding traces run through the frame around the through-holes, and ensure the good display performance of the display panel.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a method for driving a display panel, a display panel, and a display device. Background technique [0002] With the development of display technology, narrow bezels and full screens have become a development trend. [0003] Existing display panels usually dig holes in the screen body to place and install cameras. However, there is generally no static protection structure around the hole, and some display panels are protected by a floating silicon ring around the hole, so that electrostatic charges are blocked at the hole to prevent static electricity from entering the display panel; The panel adopts the design of grounding wiring at the edge of the hole-digging area, and the grounding wiring runs through the frame glue around the hole-digging area to export static electricity to the display panel. [0004] However, the protection ability of the float...
