Patent ID: 7542019

Claim:
A light emitting display comprising: first and second scan lines arranged in a row direction to transmit first and second scan signals; a data line arranged in a column direction to transmit a data signal; an image display unit including first and second emission control lines arranged in the row direction to transmit first and second emission control signals, respectively, and a pixel formed in a region defined by the first and second scan lines and the data line, wherein the pixel comprises: a driving circuit for receiving the first and second scan signals, the data signal, the first and second emission control signals, and a first power of a first power source to drive a current; a switching circuit connected with the driving circuit to receive the current, the switching circuit for selectively applying the current in accordance with the first and second emission control signals; and first and second organic light emitting diodes (OLEDs) positioned on two different rows of the image display unit and connected with the switching circuit to receive the current in accordance with an operation of the switching circuit and to emit light, wherein the driving circuit comprises: a first transistor for receiving the first power of the first power source and for supplying the current to the first and second OLEDs, the current corresponding to a voltage applied to a gate of the first transistor; a second transistor for selectively applying a data signal to a first electrode of the first transistor in accordance with the first scan signal; a third transistor for selectively forming an electrical connection between a second electrode of the first transistor and the gate of the first transistor in accordance with the first scan signal; a capacitor for storing the voltage applied to the gate of the first transistor while the data signal is applied to the first electrode of the first transistor and for maintaining the stored voltage at the gate of the first transistor for a predetermined time period when at least one of the first and second OLEDs emits light; a fourth transistor for selectively applying an initializing signal to the capacitor in accordance with the second scan signal; a fifth transistor for selectively applying the first power of the first power source to the first transistor in accordance with the first emission control signal; and a sixth transistor for selectively applying the first power of the first power source to the first transistor in accordance with the second emission control signal.
