ABSTRACT:
An exemplary LCD (200) includes gate lines (23), data lines (24); a gradation voltage adjusting circuit (26) for receiving the gradation voltages respectively corresponding to the j, j+1, k, and k+1 frames interchanging the j+1 frame gradation voltage and the k frame gradation voltage when a first voltage difference between j frame gradation voltage and j+1 frame gradation voltage is less than a second voltage difference between j frame gradation voltage and k frame gradation voltage; a memory circuit (28) for storing the gradation voltages corresponding to the frames1, 2, . . . j, j+2, . . . k−1, k+1 . . . h and storing the interchanged gradation voltages corresponding to the frames j+1 and k; and a gate driver (21) for receiving the gradation voltages stored in the memory circuit. A smallest rectangular area formed by any two adjacent gate lines together with any two adjacent data lines defines a pixel unit thereat.
