Patent ID: 7920116

Claim:
A liquid crystal display (LCD) device, comprising: a liquid crystal panel comprising a plurality of pixels respectively driven by one of the N source line channels; and a source line driver, comprising: a memory storing display data; a multiplexer configured to receive display data from the memory and generate multiplexed display data; a gray-scale voltage generation circuit configured to generate a plurality of gray-scale voltages, wherein each one of the plurality of gray-scale voltages is generated on the basis of one display color selected from a plurality of display colors; only a single decoder configured to generate decoded data from the multiplexed display data and the plurality of gray-scale voltages; only a single amplifier configured to receive and amplify the decoded data to output amplified decoded data; and a demultiplexer configured to demultiplex the amplified decoded data to generate demultiplexed amplified decoded data and provide the demultiplexed amplified decoded data via N source line channels, wherein the gray-scale voltage generation circuit and decoder are configured such that a first set of gray-scale voltages associated with a first display color selected from the plurality of display colors is offset in magnitude with respect to a second set of gray-scale voltages associated with a second display color selected from the plurality of display colors.
