Embodiment Construction

[0033] The embodiment of the present application provides a driving circuit, such as figure 1 As shown, the driving circuit includes: a driver 1, an electrostatic discharge detection circuit 2, an electrostatic discharge protection circuit 3, and a restart circuit 4;

[0034] The electrostatic discharge protection circuit 3 and the driver 1 are coupled to the same power supply terminal VCC;

[0035] The electrostatic discharge detection circuit 2 is used to: receive the level signals of the driver 1 and the electrostatic discharge protection circuit 3, and when the received level signals of the electrostatic discharge protection circuit 3 and the driver 1 are both When the signal is at a low level, send a restart signal to the restart circuit 4;

[0036] The restart circuit 4 is used to control the driver 1 to restart according to the restart signal.

[0037] It should be noted that the driver outputs a high-level signal when it is working normally, and when an electrostatic...

Abstract

The invention discloses a driving circuit and a restarting method thereof and a display device, which are used for avoiding continuous existence of display abnormity caused by static electricity and realizing automatic restarting of a driver. The embodiment of the invention provides a driving circuit. The driving circuit comprises a driver, an electrostatic discharge detection circuit, an electrostatic discharge protection circuit and a restart circuit, the electrostatic discharge protection circuit and the driver are coupled to the same power supply end; the electrostatic discharge detectioncircuit is used for receiving level signals of the driver and the electrostatic discharge protection circuit and sending a restart signal to the restart circuit when the received level signals of thedriver and the electrostatic discharge protection circuit are low level signals. The restart circuit is used for controlling the driver to restart according to the restart signal.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a driving circuit, a restart method thereof, and a display device. Background technique [0002] In the prior art, whether it is an organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel or a liquid crystal display panel (Liquid Crystal Display, LCD), a display driver is required, and the display panel can display normally only when the driver works normally. . When the display product is tested for Electro-Static discharge (ESD), static electricity will cause abnormal output data of the drive, and the drive cannot automatically return to normal. At this time, the display product is in an abnormal state, and it can only return to normal when the system is powered on again. [0003] To sum up, the display products in the prior art, after the driver is affected by static electricity, are in a continuous abnormal state and cannot automaticall...
