Display panel, display device, and antistatic residue method for display panel

Abstract

The application provides a display panel, a display device, and an antistatic residual method for the display panel. The display panel includes a first substrate and a second substrate oppositely arranged, a liquid crystal layer located between the first substrate and the second substrate, and at least one common An electrode block, and a high-resistance film block located on the side of the first substrate facing the liquid crystal layer; the high-resistance film block is arranged in an array, and the position of the high-resistance film block is set corresponding to the position of one or more open electrode blocks; The resistive film block is configured to heat the liquid crystal layer in response to static electricity remaining in its corresponding common electrode block. The display panel provided by this application arranges a matrix-shaped common electrode block and a high-resistance film block near the liquid crystal layer, and then heats the static residual area through the high-resistance film block, so as to accelerate the dissipation rate of residual static electricity on the display panel, and realize accurate and fast The purpose of effectively eliminating static electricity residue on the display panel.

Description

technical field [0001] The present application relates to the field of display equipment, in particular, to a display panel, a display device, and a method for preventing static electricity residue of the display panel. Background technique [0002] At present, LCD (Liquid Crystal Display, liquid crystal display) often encounters high-voltage electrostatic discharge environments, such as packaging, transportation, production operations, abnormal power-on and power-off operations, and other occasions. The electrostatic discharge phenomenon of residual static electricity will cause great damage to electronic components. When the product does not have anti-static design, the LCD display will appear abnormal. For example, images and lines that should not be displayed are displayed in an uncontrolled state, and the time to return to normal display varies, ranging from tens of seconds to several minutes or even tens of minutes. , It will even burn the internal wiring of the LCD, ...

Problems solved by technology

The electrostatic discharge phenomenon of residual static electricity will cause great damage to electronic components. When the product does not have anti-static design, the LCD display will appear abnormal

For example, images and lines that should not be displayed are displayed in an uncontrolled state, and the time to return to normal display varies, ranging from tens of seconds to several minutes or even tens of minutes. , and even burn the internal wiring of the LCD, which will permanently affect the normal display of the LCD

Especially for liquid crystal displays with display modes composed of fringe field switching technology (Fringe Field Switching, FFS) and in-plane switching technology (In-Plane Switching, IPS), since these LCD display processes use horizontal electric fields to control the deflection of liquid crystals, The external electrostatic electric field has a great influence on its internal electric field, which seriously affects the normal display
