Patent ID: 8035633

Claim:
An organic electro-luminescence display comprising: a pixel unit comprising a pixel connected to a data line, a scan line, and first and second pixel power source lines, wherein the pixel comprises an electro-luminescent display element configured to emit light according to current from the first pixel power source line, through the electro-luminescent display element, and to the second pixel power source line, and wherein the pixel unit is configured to display at least a portion of an image; a first regulator configured to receive a power signal from an external source and to generate a first power voltage and a second power voltage based at least in part on the received power signal, the second power voltage having electric potential lower than the first power voltage, the first regulator further configured to transmit the first and second power voltages to the pixel power source lines; a second regulator configured to receive another power signal from another external source, to generate a predetermined voltage based at least in part on the received other power signal, and to transmit the predetermined voltage to a driver driving unit, the driver driving unit comprising: a signal generator configured to generate a data signal and a scan signal, and to transmit the data signal and the scan signal to the data line and the scan line, respectively; and a power generating unit configured to generate another predetermined voltage, to transmit the other predetermined voltage to the signal generator, to generate a third power voltage, and to generate a fourth power voltage, the fourth power voltage having electrical potential lower than the third power voltage; and a switching unit configured to transmit the third power voltage and the fourth power voltage to the pixel power source lines when the first power voltage and the second power voltages are off.
