Abstract: A liquid crystal display (LCD) device includes: a data source, for generating a N-bit pixel data, N being a positive integer; a digital gamma correction unit, coupled to the data source, for performing digital gamma correction on the pixel data to generate a (N+M)-bit digital gamma correction pixel data, M being a positive integer; an image dithering unit, coupled to the digital gamma correction unit, for performing image dithering on the digital gamma correction pixel data to generate a (N+M−K)-bit dithering compensation pixel data, K being a positive integer; and a converter, coupled to the image dithering unit, for converting the dithering compensation pixel data into an output image. A bit number of the converter is lower than a bit number of the digital gamma correction unit.

Abstract: An image display system includes a data output source, and receiving devices coupled to the data output source. The receiving devices decode a first packet header from the data output source to determine whether a first payload data associated with the first packet header is required by the receiving devices. Among the receiving devices, a first receiving device that requires the first payload data receives and displays the first payload data. Also among the receiving devices, a second receiving device that does not require the first payload data temporarily disables its data receiving function, and, before the data output source sends out a second packet header that the second receiving device requires, the second receiving device resumes its data receiving function and displays a second payload data.
