摘要：
A pixel circuit related to an organic light emitting diode (OLED) is provided, and if a circuit configuration (5T1C) thereof collocates with suitable operation waveforms, a current flowing through an OLED in the OLED pixel circuit is not varied along with a threshold voltage (Vth) shift of a TFT used for driving the OLED. Accordingly, the brightness uniformity of the applied OLED display is substantially improved.
