Abstract

The invention provides a gate drive circuit, a liquid crystal panel, a display device and an aging method. According to the circuit, a first pin of the gate drive circuit configured to receive an input voltage, and a second pin of the gate drive circuit is configured to adjust the resistance value of a target resistor to be greater than a preset resistance value when receiving an instruction indicating that the aging of the display device is started, and adjust the resistance value of the target resistor to be equal to a preset threshold value after a preset period of time. A third pin of thegate drive circuit is configured to output an output voltage corresponding to the target resistor through the input voltage based on the reference voltage with the amplitude kept unchanged. When the resistance value of the target resistor is greater than the preset resistance value, the amplitude of the output voltage is greater than the amplitude of the turn-on voltage of a thin film transistor TFT in the display device; when the resistance value of the target resistor is equal to the preset resistance value, the amplitude of the output voltage is equal to the amplitude of the turn-on voltageof a thin film transistor TFT in the display device. Therefore, automatic aging of the display device is realized.

Description

technical field [0001] The present application relates to the field of liquid crystal display technology, in particular to a gate drive circuit, a liquid crystal panel, a display device and an aging method. Background technique [0002] Display devices, such as Thin Film Transistor-Liquid Crystal Display (TFT-LCD), have the characteristics of light weight, flat panel, low power consumption, no radiation, and excellent display quality, and are widely used in homes, offices, and vehicles. in various occasions. After the display device is produced, in order to ensure the quality of the display device, the display device can be aged based on conditions that are more severe than normal display conditions. [0003] In a common burn-in method, the display device can be specially connected with a circuit board, and the circuit board can provide a voltage 1 to the thin-film transistor TFT in the display device when the display device is started to burn-in by means of software code s...
