Abstract
An organic light emitting display device includes: a display panel including red, green, blue, and white (RGBW) subpixels; a first data conversion unit configured to convert red, green, and blue (RGB) data signals into RGBW data signals; an average picture level calculation unit configured to calculate an average picture level (APL) for the RGB data signals; a peak luminance controller configured to control luminance of at least one frame by using the APL and a look-up table; and a data compensation unit configured to perform a compensation operation on at least one of the RGB data signals in response to color coordinates of white (W) data signals among the RGBW data signals output from the first data conversion unit being different from a target value.
