Patent ID: 8018411

Claim:
A liquid crystal display device comprising: a first substrate; a second substrate facing the first substrate; a liquid crystal layer interposed between the first substrate and the second substrate; a pixel electrode formed over the first substrate; a common electrode formed over the first substrate with insulating from the pixel electrode, wherein a portion of the common electrode overlaps with the pixel electrode; a gray voltage generator generating a plurality of gray voltages; an image signal modification assembly configured to receive a first image signal, a second image signal, and a third image signal for subsequent three frames and modify the second image signal based on the first image signal and the third image signal; and, a data driver configured to provide a data voltage selected from the plurality of gray voltages to the pixel electrode corresponding to the modified signal in the image signal modification assembly; wherein a longitudinal axis of the liquid crystal molecule is inclined at an angle with respect to a longitudinal axis of the pixel electrode and the image signal modification assembly generates an initial modified image signal based on the first image signal and the second image signal, and then modifies the second image signal based on the initial modified image signal and the third image signal and generates a second modified signal, and a maximum value of the second modified signal is equal to a maximum of the first image signal, the second image signal, and the third image signal, and the maximum value of the second modified signal is disposed between a block voltage of the lowest gray and a white voltage of the highest gray.
