Patent ID: 8310503

Claim:
A method of driving a display device using a processor, comprising: sorting R data, G data, and B data according to each gray level of the R data, the G data, and the B data to determine a maximum value Max G , a middle value Mid G , and a minimum value Min G of the R data, the G data, and the B data; converting the maximum value Max G , the middle value Mid G , and the minimum value Min G into a maximum value Max L , a middle value Mid L , and a minimum value Min L using a gamma curve; converting colors, using the processor, by extracting the minimum value Min L for a white luminance component White L , and generating a maximum value Max L ′, a middle value Mid L ′, and a minimum value Min L ′ by scaling the maximum value Max L , the middle value Mid L , and the minimum value Min L using a fixed scaling method; converting conversely the maximum value Max L ′, the middle value Mid L ′, the minimum value Min L ′, and the white luminance component White L into a maximum value Max G ′, a middle value Mid G ′, a minimum value Min G ′, and a white data W′ using the gamma curve; restoring an order of the maximum value Max G ′, the middle value Mid G ′, the minimum value Min G ′ to provide a converted red data R′, a converted green data G′, and a converted blue data B′; and dividing each of the white data W′, the converted red data R′, the converted green data G′, and the converted blue data B′ into a first component data and a second component data.
