Abstract:
Techniques for displaying a quality-improved image with reduced power consumption are provided. In one embodiment, a display panel driver is provided that includes a dithering section configured to receive first m-bit image data and configured to generate second image data by performing dithering on the first image data with n-bit dither values each selected from elements of a dither table, and a driver circuit configured to drive the source lines of a display panel in response to the second image data. In generating the second image data corresponding to first pixels belonging to a first pixel column, the dither values are selected from elements in a first column of the dither table, while the second image data corresponding to second pixels belonging to a second pixel column adjacent to the first pixel column, the dither values are selected from elements in a second column of the dither table.
