Display panel, display device and anti-static residual method of display panel

Abstract

The invention provides a display panel, a display device and an anti-static residual method of the display panel. The display panel comprises a first substrate and a second substrate which are oppositely arranged, a liquid crystal layer positioned between the first substrate and the second substrate, at least one common electrode block, and high-resistance film blocks positioned on one side, facing the liquid crystal layer, of the first substrate. The high-resistance film blocks are arranged in an array mode, and the positions of the high-resistance film blocks correspond to the position of one or more public electrode blocks; the high-resistance film blocks are used for electrostatic residue responding to the corresponding common electrode block for heating the liquid crystal layer. The display panel provided by the invention is provided with the matrix-shaped common electrode blocks and the high-resistance film blocks near the liquid crystal layer, and perform heating for the electrostatic residue through the high-resistance film blocks to speed up the dissipation rate of the electrostatic residue on the display panel so as to achieve the purpose of accurately and quickly eliminating the electrostatic 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
