Abstract

The invention relates to a discharging control circuit. The discharging control circuit comprises a detection module, a switch module and a control module; the detection module is used for detecting current of load; the switch module is connected between the load and the ground; the control module is connected with the detection module and the switch module separately and used for judging whetheror not the current is less than preset current, if yes, the conduction of the switch module is controlled to control the load to perform discharging on the ground.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a discharge control circuit and a display device. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display) 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 TFT-LCD is: the system motherboard connects the R / G / B compressed signal, control signal and motherboard power supply to the connector on the PCB board through the wire, and the data passes through the TCON (Timing Controller, Timing Controller) on the PCB board. Timing controller) After the integrated circuit (IC) is processed, it is connected to the display area through S-COF (Source-Chip on Film) and G-COF (Gate-Chip on Film) through the PCB board, so that the LCD can obtain the required Power, signal. [0003] The liquid crystal di...
