Classification: CPC G | IPC G

Claim 5:
6. The light emitting display device according to claim 5, wherein the subpixel comprising:
a first step of initializing both ends of the organic light emitting diode by the first power of the high voltage level simultaneously with storing the data voltage in the capacitor disposed in the subpixel; and
a second step of enabling the organic light emitting diode to emit light based on the driving current generated from the driving transistor,
wherein the first step includes:
turning on a first switching transistor disposed in the subpixel;
turning on a second switching transistor comprised in the subpixel simultaneously with storing a data voltage in the capacitor; and
initializing the both ends of the organic light emitting diode by the first power of the high voltage level, and
wherein the second step includes:
turning off the first switching transistor and the second switching transistor;
driving the driving transistor based on the data voltage; and
enabling the organic light emitting diode to emit light based on the driving current generated from the driving transistor.
