ABSTRACT:
An organic electro-luminescence display is disclosed. The display includes a pixel unit configured to display at least a portion of an image, a first regulator configured to generate first and second power voltages and to transmit the first and second power voltages to the pixel power source line, a second regulator configured to generate a predetermined voltage and to transmit the predetermined voltage to a driver driving unit, and a power generating unit. The power generating unit is configured to generate another predetermined voltage, to transmit the other predetermined voltage to the signal generator, to generate a third power voltage, to transmit the third power voltage to the pixel unit, and to generate a fourth power voltage. The display also includes a switching unit configured to transmit the third and fourth power voltages to the pixel power source line when the first and second power voltages are off.
