Abstract

The invention discloses an electrostatic protection structure, a display panel with an electrostatic protection function and a display device. The electrostatic protection structure is arranged in a non-display area of the display panel, the electrostatic protection structure comprises an electrostatic collection unit, an electrostatic leading-out unit and a grounding wire, wherein the electrostatic collection unit and the electrostatic leading-out unit are oppositely arranged and spaced from each other, and the electrostatic leading-out unit is connected with the grounding wire. The display panel comprises a color filter substrate, a thin film transistor array substrate and a plurality of electrostatic protection structures, wherein the color filter substrate and the thin film transistorarray substrate are oppositely arranged, and the electrostatic protection structures are arranged between the color filter substrate and the thin film transistor array substrate. According to the electrostatic protection structure, the electrostatic protection capacity of the display panel can be effectively improved, static electricity entering the driving circuit board can be reduced, and the static electricity of the driving circuit board is effectively prevented from being damaged.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an electrostatic protection structure, a display panel with an electrostatic protection function, and a display device. Background technique [0002] In recent years, various display panels are widely used in both information communication equipment and general electrical equipment. As a flat-panel display device, liquid crystal display panels have been widely used in all aspects of life due to their thin body, power saving, and no radiation, such as small-sized smart phones, video cameras, digital cameras, and medium-sized notebooks. Computers, desktop computers, large-size home TVs, large-scale projection equipment, etc. A liquid crystal display panel usually includes an upper substrate, a lower substrate and a liquid crystal layer between the two substrates. Usually, the lower substrate is integrated with several data lines and scan lines, which are vertically i...
