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 present invention relates to an electrostatic protection structure of a display panel and a display device, which are characterized in that they include: a driving chip for sending a driving signal; a plurality of signal lines arranged in a display area according to the horizontal direction of the display area , dividing the plurality of signal lines into a first signal line area and a second signal line area, each of the signal lines in the first signal line area is provided with a positive polarity switch, and the second signal line Each of the signal lines in the area is provided with a negative polarity switch, the positive polarity switch and the negative polarity switch are electrically connected to the drive chip; and an electrostatic protection circuit, each of which includes a positive polarity switch. A diode and a reverse diode; wherein, when the output of the first signal line area is low and the output of the second signal line area is high, the display area is not refreshed.

Description

technical field [0001] The invention relates to the display field, in particular to an electrostatic protection structure 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-Chip on Film (S-COF...
