Abstract
An organic light emitting device includes first and second sub pixels. The first sub pixel includes at least one first sub pixel that emits a light of original colors, and the second sub pixel includes at least one second sub pixel that emits a light of complementary colors, wherein a specific sub pixel is selected from the first and second sub pixels and a light emitting efficiency of a remaining sub pixels are adjusted according to a light emitting efficiency of a selected sub pixel from among the first and second sub pixels, so that the OLED displays a white color when each sub pixel emits a maximum amount of light.
