Abstract

A display apparatus includes an image data comparator which receives first, second and third color image data, extracts first, second and third image data from the first, second and third color image date by comparing gray scale values of the first, second and third color image date such that each of grayscale values of the second and third image data is greater than or equal to a gray scale value of the first image data, and compares the gray scale value of the first image data with a predetermined gray scale value, a driving circuit which generates a gray scale signal based on a result of the comparison and generates first and second color signals based on the first, second or third image data, and a pixel including a first sub-pixel which receives the gray scale signal, second and third sub-pixels which receive the first and second color signals, respectively.
