Abstract:
The invention provides an AMOLED pixel driver circuit and pixel driving method. The AMOLED pixel driver circuit has a 6T1C structure, comprising a first thin film transistor (TFT) (T1), a second TFT (T2) forming mirror relation with the first TFT (T1), a third TFT (T3), a fourth TFT (T4), a fifth TFT (T5), a sixth TFT (T6), a capacitor (C1), and an organic light-emitting diode (OLED) (D1), and receiving a first scan signal (Scan1), a second scan signal (Scan2), a third scan signal (Scan3), a light-emitting signal (EM), a data signal (Data), and a reference voltage (Vref). The circuit can effectively compensate the threshold voltage of the driving TFT to solve the problem of unstable current flowing through the OLED caused by the threshold voltage drift to ensure uniform luminance of the OLED and improve the display quality.
