Abstract
The invention provides an OLED pixel driving circuit and pixel driving method. The OLED pixel driving circuit adopts a 6T2C structure, comprising: first to sixth TFTs (T, T, T, T, T, T), a first capacitor (C), a second capacitor (c), and an OLED (D); the (n−1)th first scan signal (Scan(−1)), n-th first scan signal (Scan()), n-th second scan signal (Scan()), n-th third scan signal (Scan()), n-th fourth scan signal (Scan()) and the data signal (Data) are combined w to correspond to a reset stage, a threshold voltage storage stage, a data writing stage, a capacitor cascading stage, and a display lighting stage respectively so that the current flowing through the OLED is independent of the threshold voltage of driving TFT.
