Abstract

The invention discloses a driving circuit, a driving device, a display device and a driving method thereof, wherein the driving circuit includes a timing controller, a panel power controller and a switching circuit; wherein, the panel power controller outputs power to the display panel; the timing control After the display panel is started, it outputs the first level signal to the switch circuit, and the panel power controller outputs the power supply to the display panel through the switch circuit; delays the preset time, and the timing controller outputs the second level signal to the display panel. The switch circuit is used to turn on the power output from the panel power controller to the display panel through the switch circuit. The technical solution of the invention improves the reliability of the display panel.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a driving circuit, a driving device, a display device and a driving method thereof. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display) is one of the main varieties of current display panels, and has become an important display platform in modern IT and video products. [0003] The main driving principle of TFT-LCD is that the system motherboard connects the R / G / B compressed signal, control signal and power supply to the connector on the PCB (Printed Circuit Board, printed circuit board) through the wire, and the data passes through the PCB board. After being processed by the TCON (Timing Controller, timing controller), the PCB board is connected to the display area through the source driver and gate driver, so that the display area can obtain the required power and signals. [0004] When...
