An organic light emitting diode display, comprising: a display panel on which a plurality of pixels are arranged, each of the pixels comprising an R sub-pixel for generating red light through a white OLED and an R color filter, a G sub-pixel for generating green light through a white OLED and a G color filter, a B sub-pixel for generating blue light through a white OLED and a B color filter, and a W sub-pixel for generating white light through a white OLED; a data operation unit for generating a data operation value by extracting a representative value for each pixel based on three primary color data, determining white data of the corresponding pixel as the representative value, and then subtracting the white data from the three primary color data for each pixel; a gain adjusting unit for generating a gain adjusting value of the three primary color data by multiplying a preset gain value of the three primary color data by the corresponding white data; and a data conversion unit for generating four color compensation data, whose white chromaticity coordinates are compensated for each pixel, by adding the gain adjusting value to the data operation value and matching the corresponding white data to the three primary color data converted by the adding. |
