摘要： A pixel unit for driving an organic light emitting diode (OLED) is disclosed. The pixel unit includes a driving transistor, a compensating capacitor, a selecting switch module, a power switch and a configuration switch. One terminal of the compensating capacitor is coupled to a gate of the driving transistor. The selecting switch module provides the ground voltage or the compensating voltage to the other terminal of the compensating capacitor according to a first control signal. The power switch is coupled between a power voltage and a drain of the driving transistor and is controlled by a second control signal. The configuration switch receives the first control signal for controlling a connecting configuration of the driving transistor. The pixel unit is driven according to the first and the second control signals for compensating threshold voltage shifting of the OLED and the driving transistor.

摘要： An organic light emitting diode (OLED) display and an operating method thereof are provided. The organic light emitting diode display includes an organic light emitting diode display panel and a driving circuit. The organic light emitting diode display panel has a plurality of pixels. The driving circuit is coupled to the organic light emitting display panel and receives a primitive display frame. The driving circuit generates a first frame and a second frame corresponding to the primitive display frame by a polarity inverting means, and outputs a zero gray-level pixel voltage to the corresponding pixels of the organic light emitting diode display panel corresponding to a negative polarity data of the first frame and the second frame, wherein the second frame is adjacent to the first frame.
