Patent ID: 7148868

Claim:
A liquid crystal display comprising: a liquid crystal panel assembly including a plurality of pixels connected to a plurality of gate lines and a plurality of data lines; a signal controller for processing image data, the signal controller including an accurate color capture(“ACC”) block and a dynamic capacitance capture (“DCC”) block; a gate driver for sequentially applying a gate-on voltage to the gate lines of the liquid crystal panel assembly; and a data driver selecting data voltages among a plurality of gray voltages in response to the modified image data from the signal controller and applies the data voltages to the data lines of the liquid crystal panel assembly, wherein the ACC block comprises a bit number enlarger converting the image data to have an increased bit number; and a bit number reducer reducing the bit number of the converted image data from the bit number enlarger by taking a predetermined upper bits of the converted image data and transforming remaining lower bits of the converted image data into frequency of a first data with a first value of the taken upper bits and a second data with the first value plus one during the predetermined number of frames; and wherein the DCC block modifies the first image data assigned to the pixels by selectively performing DCC on the first image data based on the difference between the image data of a current frame (“current data”) and the image data of a previous frame (“previous data”).
