Abstract

The invention provides a driving circuit, a driving method and a display panel. The driving circuit comprises a level conversion module and a power-on reset module, the level conversion module comprises an overcurrent protection module, an error indicator, a monostable trigger, a counter, a reset / set trigger, a switch unit and a logic control module, and the logic control module comprises a resetpin. During an electrostatic discharge test, if the error indicator monitors that the overcurrent protection module is interfered, an indication signal is output to the monostable trigger, so that themonostable trigger generates a pulse signal and outputs the pulse signal to the reset / set trigger and the counter; when the number of the pulse signals accumulated by the counter is larger than or equal to a threshold value, the reset / set trigger outputs the pulse signals and controls the switch unit to be switched on / off. When the switch unit is switched on, the logic control module is reset, sothat the driving circuit is restarted. Therefore, a black screen phenomenon caused by interference of the over-current protection module during an electrostatic discharge test is solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a driving circuit, a driving method, and a display panel. Background technique [0002] For the GOA type display panel, the overcurrent protection (OCP) function of the level shifter IC (Level Shifter IC) is basically necessary to prevent the conductive particles in the plane from causing a short circuit between the signal lines (CK) , the current increases, causing the wiring to heat up, the temperature of the display panel rises, and the polarizer melts off. However, when this chip is used for electrostatic discharge (ESD) testing, the OCP module is susceptible to interference, causing malfunctions, resulting in bad phenomena such as black screens. [0003] Therefore, there are defects in the prior art, and improvement is badly needed. Contents of the invention [0004] The present application provides a driving circuit, a driving method, and a display panel, whi...
