A kind of array substrate, liquid crystal panel and display device

Abstract

The invention discloses an array base plate, a liquid crystal display panel and a display device. The array base plate comprises a substrate base plate, a plurality of grid lines and data lines arranged on the substrate base plate, electrostatic protection return circuits arranged at one ends of one or more grid lines or data lines and connected with the grid lines or the data lines correspondingly and short-circuit rods correspondingly connected with the electrostatic protection return circuits, located on a perimeter zone and used for transmitting common voltage signals; the array base plate further comprises a transparency electrode layer located on the perimeter zone; the transparency electrode layer is electrically connected with each short-circuit rod through via holes; the projection of the transparency electrode layer and the grid lines or the data lines correspondingly connected with each electrostatic protection return circuit on the substrate base plate has an overlapping zone, and a filter capacitor is formed in the overlapping zone; when static electricity comes, the electrostatic protection return circuits are communicated, electrostatic charges are stored in the filter capacitor, and when the static electricity disappears, the electrostatic protection return circuits do not stop working immediately, the filter capacitor still maintains an open state, and the electrostatic charges are released slowly; accordingly, the role of electrostatic protection is played.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to an array substrate, a liquid crystal panel and a display device. Background technique

[0002] Currently, the phenomenon of Electro-Static Discharge (ESD) is common in liquid crystal display products. ESD is a kind of static electricity accumulation, which transfers and releases static electricity between different objects. The time of static electricity discharge is very short, generally only on the nanosecond level. The discharge of static electricity in such a short period of time will generate a very large instantaneous current, so high When the current passes through the integrated circuit, the device will be burned, resulting in the circuit not working properly. Therefore, the occurrence of ESD in liquid crystal display products usually causes electrostatic breakdown short circuit or open circuit on peripheral design lines.
