ABSTRACT:
In an exemplary embodiment of the present invention, there is provided a pixel circuit for a luminescent display, in which plural pixel circuits are formed in a plurality of pixels defined by a plurality of data lines and a plurality of scan lines. The pixel circuit includes: a luminescent element; a first capacitor; a first transistor having a gate electrode coupled to the first capacitor, and a first main electrode coupled to a power supply line; a first switch for diode-connecting the first transistor in response to a selection signal to charge the first capacitor with a voltage corresponding to a threshold voltage of the first transistor; a second transistor for transferring the data signal from the data lines in response to a selection signal; a second capacitor for storing a voltage corresponding to the data signal; and a second switch for isolating the second main electrode of the first transistor from the luminescent element during voltage-charging of the first capacitor in response to a control signal.
