The electroluminescent unit is controlled by the driving transistor to illuminate in a drive period. The write unit is enabled in a write period recording a data voltage relating to an initial threshold voltage of the electroluminescent unit in first storage element. The pre-write unit is enabled in a pre-write period recording a threshold voltage of the driving transistor and the electroluminescent unit in second storage element. The threshold voltage and the data voltage, stored in the first and the second storage units, are supplied as a gate-source voltage of the driving transistor, so as to provide a compensated drive voltage, capable of compensating the variation of the threshold voltages of the driving transistor and the electroluminescent unit, driving the electroluminescent unit.

    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.
