<P>PROBLEM TO BE SOLVED: To provide an organic electroluminescence display (OELD), capable of improving visibility by controlling luminance and/or saturation to correspond to ambient light and reducing electric power consumption, and to provide a drive method therefor. <P>SOLUTION: The OELD comprises a pixel unit having a plurality of pixels to emit light corresponding to data signal, scanning signal and light emission control signal; a photosensor configured to generate a control signal corresponding to ambient light rays; a control unit, having a gamma control unit to set gamma correction value corresponding to the control signal and a color coordinate control unit for correcting the color coordinates of the data signal corresponding to the control signal; a scan driver configured to generate scan signals to scan lines; a data driver configured to correct a gamma value of the data signals, according to the data signals corrected in the color coordinate control unit and the gamma correction signal output from the gamma control unit, the data driver may be configured to supply the corrected gamma values to the data lines; and a power supply unit, configured to supply power to the pixel unit.and a light emission control unit. <P>COPYRIGHT: (C)2008,JPO&INPIT |
