摘要： 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.

摘要： A display panel driver includes first and second scaler circuits and a pixel data feeding section which feeds to the first scaler circuit first divisional image pixel data corresponding to a first divisional image and feeds to the second scaler circuit second divisional image pixel data corresponding to a second divisional image. The pixel data feeding section also feeds to the first scaler circuit first boundary pixel data corresponding to pixels in a portion of the second divisional image, adjacent to the first divisional image and feeds to the second scaler circuit second boundary pixel data corresponding to pixels in a portion of the first divisional image, adjacent to the second divisional image. The first scaler circuit performs image scaling on the basis of the first divisional image pixel data and the first boundary pixel data and the second scaler circuit performs image scaling on the basis of the second divisional pixel image data and the second boundary pixel data.

摘要： A display panel driver includes a scaler circuit performing image enlargement processing on input image data corresponding to an input image to generate α-times enlarged image data corresponding to an α-times enlarged image (α is a number larger than one which cannot be represented as 2k); and a driver section driving a display panel. In calculating a pixel value of a target pixel of the α-times enlarged image, the scaler circuit generates enlarged image data including 2n-times enlarged image data corresponding to a 2n-times enlarged image obtained by enlarging the input image with an enlargement factor of 2n (n is the smallest integer determined so that 2n is larger than α), and calculates the pixel value of the target pixel from the 2n-times enlarged image data through interpolation processing of pixel values of pixels of the 2n-times enlarged image corresponding to the target pixel of the α-times enlarged image.
