Abstract
Disclosed is a circuit for driving a self light-emitting display device which itself emits light when an electric or other energy is inputted thereto and a method thereof. According to the circuit and method, the self light-emitting display device can be driven more stably and with a higher efficiency by adjusting the number of used bits and luminance of respective color components in accordance with a luminance change of an external light and keeping a constant contrast ratio irrespective of the adjustment of the bit numbers.
