How the data processing device, a display system having the same and a data processing

A data processing device, the display system and a data processing method with this, the data processing apparatus supplies image data from the receiving module receives red, green, blue and white sub-rendering in accordance with the layout of the pixels rendered with sub-pixel data module and rendered and a color correction module for correcting the color of the sub-pixel data. In addition, the color correction module is red, green and blue sub-pixel data, respectively the red, green and blue converted into the intermediate data, after the white sub-pixel is set group and the data of red to red, green and blue delta values, green and blue intermediate by adding to the data to generate the red, green, and blue correction data. Thus, the data processing apparatus may compensate for the data to the display device displays the correct color.
