Abstract

A shift register unit, a driving method of the shift register unit, a display driving circuit and a display device are provided, belonging to the field of display technology. In the shift register unit, an input circuit can transmit power supply signals with different potentials to a control node in different time periods in response to an input signal and clock signals, and two output circuits can both transmit power supply signals with different potentials to connected output terminals in different time periods in response to the potential of the control node. Therefore, it can be determined that the shift register unit comprises both P-type transistors and N-type transistors, and the two output circuits therein can output signals to the connected output terminals independently of each other. On this basis, by flexibly adjusting the potentials of the power supply signals, drive signals with required potentials can be reliably transmitted to pixels in areas with different refresh frequencies through the drive output terminal connected to the pixels, so as to support the partial-refresh function. The shift register unit has a simple structure and rich functions.
