Abstract
The present invention provides a driving circuit and method for a pixel unit, a pixel unit and a display apparatus. The driving circuit for a pixel unit comprises: a driving thin-film transistor, a first switching element, a storage capacitor and a driving control unit; said driving control unit is used to control said storage capacitor to be charged/discharged so as to control said driving thin-film transistor to operate in a saturation region, so that the threshold voltage Vth of said driving thin-film transistor is compensated by utilizing the gate-source voltage of said driving thin-film transistor. The present invention can address the problems of ununiformity and attenuation of the brightness of OLED panel.
