Abstract
An organic electro luminescence display and driving method uses an image determination unit to generate image determination signals indicative of whether images generated in response to data signals are moving images still images, selects a gamma value corresponding to the brightness of the ambient light sensed, applies gamma correction signals corresponding to selected gamma values to control grey level voltages of the data signals, generates a selection signal based on a comparison of a previously set reference value with the photo sensor signal, and generates R',G′,B′ data to vary an input image RGB data to correspond to the selection signal, varies a change range of the changing R′,G′,B′ data to correspond to the image determination signal, and supplies the varied change range of the changing data (R′,G′,B′ data) to the data driver.
