Problems solved by technology

[0003] At present, the Mini-LED display technology is mainly based on the passive matrix (PM) driver, and the PM drives the Mini-LED display screen. When the voltage on each data line is different, the lamp beads on the data line will be wrong. Trigger the bright phenomenon, and then make the Mini-LED display screen have a difference in brightness, resulting in abnormal screen and affecting the display effect of Mini-LED

Abstract

The invention relates to a driving circuit, a display panel, a driving method and a storage medium. The drive circuit includes a timing controller module, a voltage detection module, and a signal generator module; the timing controller module is connected to the voltage detection module, and is used to send a first control signal to the voltage detection module when the drive switch of the data line is closed; The voltage detection module is connected with the signal generator module, and is used to send the first execution signal to the signal generator module when the first control signal is received and the voltage of the data line is abnormal; When the first execution signal is received, the compensation voltage is sent to the data line; when the LED lamp bead on the data line does not need to be lit, and the abnormal fluctuation of the voltage of the data line is detected, the compensation voltage is output in time, so that the data The voltage of the line returns to the normal state, avoiding the phenomenon that the LED light beads on the data line do not need to light up, and the LED light beads are accidentally triggered to light up.

Description

technical field [0001] The present invention relates to the field of semiconductor devices, and in particular, to a driving circuit, a display panel, a driving method and a storage medium. Background technique [0002] Mini Light Emitting Diode (Mini-LED) display technology is based on inorganic semiconductor light-emitting diode (LED), Mini-LED can be applied to large-screen high-definition display, such as monitoring command, high-definition studio, high-end cinema, Professional fields such as medical testing or commercial fields such as outdoor advertising, conferences and exhibitions, office display, etc. Mini-LED display technology has the advantages of high brightness, high response speed, low power consumption, long life, etc., and has become a research hotspot for people to pursue a new generation of display technology . In related technologies, with the development of the small spacing of Mini-LED lamp beads, LED display screens have put forward higher requirements...
