Cantor Colburn LLP
Display device and driving device thereof
A driving device comprises a look-up-table, a multiplier, an adder, and a dithering portion. The look-up-table stores red and blue colors of corrected image signals and first difference data (f) between input image signals and corrected image signals corresponding to the input image signals. The multiplier converts the input image signals into the same or higher bits of the input image signals. Further, the adder adds the higher bits of the input image signals to the first difference data. Finally, the dithering portion receives corrected image signals and generates output image signals suitable for a data drive portion. According to this configuration, the size of the look-up-table may be reduced and power consumption may be reduced.
