Abstract:
1. An organic light emitting display, comprising: pixels positioned at intersections of scan lines, emission control lines, and data lines; a scan driver to supply scan signals to the scan lines; a converter for receiving data to generate brightness values; a timing controller to determine emission time values and gamma values to correspond to the brightness values; an emission control line driver for supplying emission control signals to the emission control lines so that emission times of the pixels are controlled to correspond to the emission time values; a gamma voltage generator for generating gamma voltages corresponding to the gamma values, wherein the emission time values correspond to different widths of the emission control signals; a data driver to generate data signals using the data and the gamma voltages; a first look-up table to store the emission time values corresponding to the brightness values; and a second look-up table to store the gamma values corresponding to the brightness values.
