摘要： A light emitting diode (OLED) display and pixel driving method thereof are disclosed. Each storage capacitor is discharged via the driving TFT and OLED until conductive current of each OLED is almost zero so as to record a sum of a voltage drop across each OLED under a specific condition and the threshold voltage of the driving TFT. By using the sum of the voltage drop across each OLED and the threshold voltage of the corresponding TFT in the subsequent OLED driving process, the luminance reduction issue caused by TFT threshold-voltage shift and OLED material decay can be solved.

摘要： A shift register includes a plurality of shift register stages for providing gate signals. Each shift register stage has a pull-up unit, a carry unit, a carry control unit, an input unit and a pull-down unit. The pull-up unit is employed to pull up a gate signal according to a driving control voltage and a first clock. The carry unit generates a preliminary start pulse signal based on the driving control voltage and the first clock. The carry control unit outputs the preliminary start pulse signal to become a forward or backward start pulse signal according to first and second bias voltages. The input unit is utilized for inputting a start pulse signal generated by a preceding or succeeding shift register stage to become the driving control voltage. The pull-down unit pulls down the gate signal, the preliminary start pulse signal and the driving control voltage according to multiple clocks.
