Abstract

A converting system and a converting method of three-color data to four-color data are provided. The converting system includes: a first calculating part configured to calculate a saturation value and a luminance enhancement coefficient according to inputted RGB values, a second calculating part configured to calculate luminance-enhanced RGB values according to the luminance enhancement coefficient and the inputted RGB values, a white determining part configured to use a minimum value of the luminance-enhanced RGB values as an outputted W value, and a three-color determining part configured to calculate outputted RGB values according to the luminance-enhanced RGB values and the outputted W value. The invention can obtain optimal outputted W values for different inputted RGB values and maximally increase the transmittance of the display apparatus. Accordingly, the display apparatus can increase the saturation of display image while enhance the transmittance.
