摘要： A pixel circuit related to an organic light-emitting diode (OLED) is provided. When signals having appropriate operation waveforms are supplied, the circuit configuration (7T1C or 5T1C) of the pixel circuit keeps the current flowing through an OLED unaffected by the impact of IR drop on a power supply voltage Vdd (or mitigates the impact of the power supply voltage Vdd on the current) and prevents the current flowing through the OLED from changing with the Vth shift of a TFT for driving the OLED. Thereby, the luminance uniformity of an OLED display adopting the pixel circuit is greatly improved.

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.
