Abstract

Provided are a timing controller for converting RGB data to WRGB data, a driving method thereof, and an LCD device using the same. The timing controller according to an embodiment includes a reception unit to receive input RGB data from an external device; a converter to convert the input RGB data into input WRGB data composed of W, R, G and B data; an aligner to convert one of the W, R, G, and B data into 0 to generate conversion WRGB data, the conversion WRGB data having bits less than the total number of bits composing the W, R, G, and B data; a controller to transfer the conversion WRGB data to an external memory; and a re-aligner to convert the conversion WRGB data received from the external memory into digital WRGB data corresponding to the input WRGB data, and to output the digital WRGB data.
