Abstract
A liquid crystal display and a driving method thereof are provided. The liquid crystal display includes a liquid crystal display panel, a register for storing pixel information of a problem pattern and polarity pattern information, a block pattern recognition unit for comparing input data with the problem pattern to count the number of problem patterns contained in the input data and comparing the count value with a first threshold value, a line pattern recognition unit for determining the line containing the problem pattern as a problem line, a frame pattern recognition unit for comparing the number of problem lines with a second threshold value, and determining the frame containing the input data as a problem frame, a polarity control signal generating unit for generating vertical and horizontal polarity control signals, and source drive integrated circuits (ICs) for controlling the vertical and horizontal polarities of data voltages supplied to the data lines.
