Abstract:
1. An organic light emitting display comprising a plurality of pixels positioned at intersections of data lines and scan lines, the organic light emitting display comprising: the pixels including driving transistors positioned in an effective display region to control an amount of current that flows from a first power source to a second power source; a data driver to supply data signals to the data lines; a scan driver to supply scan signals to the scan lines; a first power source generator to generate the first power source; a second power source generator to generate the second power source; and a voltage controller to control the second power source generator so that a voltage of the second power source is changed in response to a first voltage applied to an organic light emitting diode (OLED) included in a specific pixel when a data signal corresponding to specific brightness is supplied from the data driver to the specific pixel.
