A pixel unit drive circuit and method, a pixel unit, and a display apparatus. The pixel unit drive circuit comprises a driving thin film transistor (DTFT), a first switch element (T1), a storage capacitor (Cs), and a drive control unit (T2, T3, T4, T5). The source of the DTFT is connected to a data line (Data) through the first switch element (T1). The drain of the DTFT is separately connected to an anode of an OLED and a low level output end of a drive power supply through the drive control unit (T2, T3, T4, T5), the source thereof is connected to a high level output end (VDD) of the drive power supply through the drive control unit (T2, T3, T4, T5), and the gate thereof is connected to the drain of the DTFT through the drive control unit (T2, T3, T4, T5). The drive control unit (T2, T3, T4, T5) is used for controlling a threshold voltage of the DTFT by controlling charging and discharging of the storage capacitor (Cs). The pixel unit drive circuit and method, the pixel unit, and the display apparatus can solve problems of non-uniform luminance and luminance decay of an OLED panel. |
