Embodiment Construction

[0025] As mentioned in the background technology, after setting the digging area A in the display area, in order not to affect the normal operation of the data lines, gate lines and touch leads, etc., the data lines, gate lines and touch leads are bypassed. Hole area settings, such as figure 1 as shown, figure 1 It is a schematic top view structural diagram of a conventional display panel, in which the data line S bypasses the hole-digging area D. FIG. However, since there is no ESD protection circuit in the hole-digging area D, the static electricity accumulated during operation of the data lines, gate lines and touch leads will damage the circuit structure around the hole-digging area D.

[0026] Based on this, the present invention provides a display panel to overcome the above-mentioned problems in the prior art, including a hole-digging area and an ESD protection circuit;

[0027] The ESD protection circuit includes a conductive ring and a first conductive lead;

Abstract

The present invention provides a display panel and a display device, including a hole-digging area and an ESD protection circuit; the ESD protection circuit includes a conductive ring and a first conductive lead; the conductive ring is arranged around the hole-digging area, and the conductive The ring is set on the same layer as the light-shielding metal layer of the thin film transistor in the display panel, and the conductive ring is electrically connected to the ground wire of the display panel through the first conductive lead. Therefore, the conductive ring, the first conductive The electrostatic discharge path formed by the lead wire and the ground wire is used to discharge the static electricity, thereby avoiding the damage caused by the static electricity to the circuit structure around the hole-digging area.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique [0002] The full-screen technology achieves a screen-to-body ratio of more than 90% through a narrow bezel or even bezel-less design. It maximizes the display area without changing the fuselage, making the display effect even more amazing. Based on the structural design of the full screen, it is necessary to dig holes in the hole-digging area of ​​the display panel to install cameras, earpieces, sensors and other devices in the holes. However, since there is no ESD (Electro-Static discharge, electrostatic discharge) protection circuit in the hole-digging area, the circuit structures around the hole-digging area are easily damaged by static electricity. Contents of the invention [0003] In view of this, the present invention provides a display panel and a display device to solve the problem that the...
