Problems solved by technology

[0003] However, due to process fluctuations and / or increase in screen temperature, transistor leakage will increase. Therefore, the threshold voltage of the transistor is too high to cause the transistor to be forward-biased, causing the abnormal output of the transistor and causing the flickering problem of the display device, which makes the display device poor visual effect, seriously affecting the user's visual experience

Abstract

The invention provides a shift register unit and a control method thereof, a gate drive circuit and a display device. According to the invention, the shift output function of the shift register unit is realized; the high-level output of the shift register unit does not change along with the change of the signal; the stable output of the high level of the shift register is ensured; the phenomenon of transistor electric leakage increase caused by process fluctuation and / or screen body temperature rise is eliminated; the problem of abnormal transistor output caused by increase of transistor electric leakage is solved; according to the shift register, the output stability of the shift register is improved, the problem of splash screen of the display device due to abnormal output of the transistor is avoided, the image display quality of the display device is improved, the actual requirement of a high-quality visual effect is met, and better visual experience is provided for a user.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a shift register unit, a control method thereof, a gate drive circuit and a display device. Background technique [0002] Among active-matrix organic light-emitting diode (AMOLED) panels, organic light-emitting diodes (OLEDs) have been widely used due to their light weight, small size, and low energy consumption. various display devices. [0003] However, due to process fluctuations and / or increase in screen temperature, the leakage of transistors will increase. Therefore, the threshold voltage of the transistors is too high and the transistors are forward-biased, causing abnormal output of the transistors and causing the problem of flickering in the display device, which makes the display device The poor visual effect seriously affects the user's visual experience. Contents of the invention [0004] The present application provides a shift register unit, a control...
