ABSTRACT:
A light-emitting display device includes a pixel circuit that transmits a data signal using switches responding to control signals. The pixel circuit of the light-emitting display device includes first and second switching transistors serially coupled to a data line. A capacitor is charged with charges in response to a data signal from the data line through the first and second switching transistors. A driving transistor outputs a current corresponding to the charges in the capacitor. A light-emitting diode emits light corresponding to the current. One of the first and second switching transistors is turned on in response to a select signal from a first scan line and the other one is turned on in response to a control signal for controlling an operation of a second pixel circuit.
