摘要： An organic light emitting diode (OLED) pixel circuit is provided by the invention. If a circuit configuration (5T2C) thereof collocates with suitable operation waveforms, a current flowing through an OLED in the OLED pixel circuit may not be changed with a power supply voltage (Vdd) influenced by an IR drop, and may not be varied with a threshold voltage (Vth) shift of a thin-film-transistor (TFT) configured for driving the OLED. Accordingly, brightness uniformity of an OLED display applying the same can be substantially improved.
