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, comprising: a base substrate; a hollow part, a first non-display area, a display area and a second non-display area; the first non-display area is arranged around the hollow part, and the display area surrounds the first non-display area. A non-display area is arranged, and a second non-display area is arranged around the display area; the display area includes a plurality of thin film transistors, a plurality of touch electrodes and a plurality of touch wires; the thin film transistor includes a semiconductor part, a gate electrode, a source electrode and a drain electrode The second non-display area includes at least one electrostatic protection element; the first non-display area includes a conductive ring, the conductive ring is arranged around the hollow part, and is electrically connected to the electrostatic protection element through at least one lead wire Connections, lead wires and touch traces are located on the same film layer. Compared with the prior art, the anti-ESD performance of the hollow portion is effectively improved, and the utilization efficiency of the traces not connected to the touch signal in the film layer is also effectively improved, which is beneficial to reduce the anti-static cost.

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...
