Abstract:
1. A liquid crystal display (LCD) comprising: an LCD panel comprising a plurality of gate lines for transmitting scanning signals, a plurality of data lines that cross the gate lines for transmitting image signals, and a plurality of pixels that are arranged in a matrix and have switching elements connected to the gate lines and the data lines; a data gray signal modifier that receives gray signals from an external device, and modifies gray signals of a present frame based on gray signals of present and previous frames and at least a modification parameter including a temperature, an image quality selected by a user, and an environment of the LCD; a gate driver sequentially applying the scanning signals to the gate lines; and a data driver that converts the modified gray signals into data voltages and applies the data voltages to the data lines, wherein the data gray signal modifier includes a look-up table (LUT) for a reference value of the at least a modification parameter, the LUT has modification values for modifying gray signals, and each modification value of the LUT is represented by G
