Abstract:
A liquid crystal display (LCD), comprising:a data gray signal modifier for receiving gray signals from a data gray signal source, and outputting modification gray signals by considering gray signals of present and previous frames, wherein the data gray signal modifier comprises a data gray signal converter for considering the gray signals of the present frame transmitted by the data gray signal source and the gray signals of the previous frame transmitted by a frame storage device, and outputting the modification gray signals; and a data driver for changing the modification gray signals into corresponding data voltages and outputting image signals; a gate driver for sequentially supplying scanning signals; and an LCD panel comprising a plurality of gate lines for transmitting the scanning signals; a plurality of data lines, insulated from and crossing the gate lines, for transmitting the image signals; and a plurality of pixels, formed by an area surrounded by the gate lines and the data lines and arranged as a matrix pattern, having switching elements connected to the gate lines and data lines.
