Abstract:
1. A liquid crystal display (LCD) comprising: a display panel which comprises n pixels arranged in a matrix, wherein n is a natural number greater than 1; and a signal controller which sequentially receives first through n-th pixel image signals included in an image signal of a previous frame and (n+1)-th through (2n)-th pixel image signals included in an image signal of a current frame, sequentially calculates, for all values of k from 1 to n, a difference between a k-th pixel image signal of the first through n-th pixel image signals and an (n+k)-th pixel image signal of the (n+1)-th through 2n-th pixel image signals, recognizes, for all the values of k, the (n+k)-th pixel image signal as a motion signal when the difference is greater than a first reference value and recognizes, for all the values of k, the (n+k)-th pixel image signal as a non-motion signal when the difference is equal to or less than the first reference value, and determines whether the image signal of the current frame including the (n+k)-th pixel image signal is a moving-image signal or a static-image signal based on a count generated from the number of motion signals recognized and the number of non-motion signals recognized, wherein the first through n-th pixel image signals correspond to the n pixels, respectively, the (n+1)-th through 2n-th pixel image signals correspond to the n pixels, respectively, and k is a natural number ranging from 1 to n, wherein the signal controller comprises a counter that increases a value by the number of motion signals recognized and decreases the value by the number of non-motion signals recognized, and the count is set to the value.
