Problems solved by technology

When the screen is in a state of fast motion (such as playing video, games, scrolling, etc.), this refresh rate is still necessary; but if it is a static screen, it will still be refreshed continuously, which will cause a lot of unnecessary power loss

Abstract

The invention relates to an electrostatic protection structure of a display panel, and a display device. The electrostatic protection structure is characterized by comprising a driving chip used for sending a driving signal, a plurality of signal lines arranged in a display region, and electrostatic protection circuits, wherein the signal lines are equally divided into a first signal line region and a second signal line region according to the horizontal direction of the display region; each signal line in the first signal line region is provided with a positive polarity switch; each signal line in the second signal line region is provided with a negative polarity switch; the positive polarity switches and the negative polarity switches are electrically connected with the driving chip; each electrostatic protection circuit comprises a forward diode and a backward diode; and when an output of the first signal line region is low and an output of the second signal line region is high, thedisplay region is not refreshed.

Description

technical field [0001] The invention relates to the display field, in particular to an electrostatic protection structure of a display panel and a display device. Background technique [0002] Display panel (Thin Film Transistor Liquid Crystal Display, TFT-LCD) is one of the main varieties of flat panel display, and has become an important display platform in modern IT and video products. The main driving principle of the display panel (ThinFilm Transistor Liquid Crystal Display, TFT-LCD), the system motherboard compresses the red (R), green (G), blue (B) signals, control signals and power through the wire and the printed circuit board (Printed circuit board) board, PCB) connected to the electronic connector (connector), the data is processed by the driver chip (Timing Controller IC, TCON IC) on the printed circuit board (Printed circuit board, PCB), and then passed through the printed circuit board (Printed circuit board, PCB), connected to the display area through Source-...
