Problems solved by technology

[0003] However, whether holes are made in the casing or directly on the display panel, the electrostatic charge outside the panel can easily enter the inside of the panel from the hole. Due to the weak electrostatic protection ability of the panel, the panel is easily damaged when the display device is in use. Damaged by electrostatic charges, resulting in a high defect rate in the production of display devices, which is not conducive to the improvement of production efficiency

Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate, a hollow part, a first non-display region, a display region and a second non-display region; thefirst non-display region surrounds the hollow part, the display region surrounds the first non-display region, and the second non-display region surrounds the display region; the display region comprises a plurality of thin film transistors, a plurality of touch electrodes and a plurality of touch wires; each thin film transistor comprises a semiconductor part, a grid electrode, a source electrodeand a drain electrode, wherein the semiconductor part is arranged on the substrate; the second non-display region comprises at least one static electricity protective component; the first non-displayregion comprises an electric conducting ring, the electric conducting ring surrounds the hollow part and is electrically connected with the static electricity protective component through at least one outgoing line, and the outgoing lines and the touch wires are located on the same film layer. Compared with the prior art, the ESD resistance of the hollow part is effectively improved, meanwhile, the utilization efficiency of wires connected with no touch signal in the film layer is effectively improved, and the anti-static-electricity cost is lowered.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] Existing display devices usually have a hole in the casing to place the camera, and this design of the hole makes the frame of the display device wider. With the continuous improvement of people's requirements for the visual experience of electronic products, full-screen technology has been continuously developed, and more and more manufacturers directly open holes on the display panel to place cameras. [0003] However, whether holes are made in the casing or directly on the display panel, the electrostatic charge outside the panel can easily enter the inside of the panel from the hole. Due to the weak electrostatic protection ability of the panel, the panel is easily damaged when the display device is in use. The damage caused by the electrostatic charge causes a high defect rate in the produ...
