Abstract
A shift register unit, a grid drive circuit, a display device and a driving method are disclosed. The shift register unit includes a display sub-shift-register and a detection sub-shift-register. The display sub-shift-register includes a display output terminal, and the display sub-shift-register is configured to output a display output signal of the shift register unit from the display output terminal at a display stage; the detection sub-shift-register is connected to a display output terminal of the display sub-shift-register to receive a display output signal, and includes a first random pulse signal terminal to receive a first random pulse signal. The detection sub-shift-register is configured to output a detection output signal of the shift register unit when the display output signal is at a turn-on level and the first random pulse signal is at a turn-on level.
