Abstract: PURPOSE: An LCD for reducing power consumption and a driving method thereof are provided to reduce the power consumption and reduce EMI(Electro-Magnetic Interference) by using picture data stored in a frame memory within a data driver in a process for displaying still images. CONSTITUTION: An LCD for reducing power consumption includes a data discriminator and a data driver. The data discriminator(120) includes a first frame memory(200) for storing picture data of the nth frame in order to discriminate between the nth frame and the n+1th frame. The data driver(170) includes a second frame memory(220) for storing the picture data of the nth frame. The second frame memory outputs the stored picture data of the nth frame and stores the picture data of the n+1th frame when the nth frame is identical with the n+1th frame. In addition, the second frame memory outputs and stores the picture data of the n+1th frame when the nth frame is not identical to the n+1th frame.
