Abstract:
1. A liquid crystal display apparatus, comprising: a timing controller to generate a plurality of compensated grayscale data; a memory to store at least grayscale data; a column driver to apply the compensated grayscale data to a plurality of data lines; a gate driver to apply a gate signal to a plurality of gate lines; and a liquid crystal panel including the gate lines, the data lines and a plurality of switching elements disposed between the data lines and the gate lines; wherein the timing controller comprises: a data compensator to generate current frame first compensated grayscale data in response to receiving previous frame grayscale data from the memory and current frame grayscale data from an external source; a difference calculator to calculate a data difference between the current frame first compensated grayscale data and the current frame grayscale data, the difference calculator receiving the current frame first compensated grayscale data from the data compensator; and a grayscale modifier to generate current frame second compensated grayscale data in response to receiving the current frame first compensated grayscale data from the data compensator and the data difference of the previous frame compensated grayscale data and the previous frame grayscale data from the frame memory.
