Abstract:
A pixel unit driving circuit provides a method for driving a pixel unit for operating a display device. The circuit comprises four TFT transistors and two capacitors. The display process is divided into three processes, which are a pre-charging phase, a compensation phase and a display phase. As compared with the conventional pixel structure, the nonuniformity and the shift of the threshold voltage of the depleted TFT or the enhanced TFT driving transistor, and the nonuniformity of the OLED voltage may be effectively compensated.
