Abstract: A dual image display device 1 according to an embodiment of the invention includes a crosstalk corrector 6 that corrects the grayscale of a sub pixel subject to correction based on the grayscale of an adjacent sub pixel. The crosstalk corrector 6 carries out corrections in K grayscale for N1 frames and corrections in K+1 grayscale for N?N1 frames within N frames where K being an integer, N being a positive integer of 2 or more, and N1 being a positive integer of less than N. Provided with the above-described configuration, the problem in that a dual image in which sub pixels of individual images for two visual directions are adjacent to each other in a gate line direction is liable to cause flicker in the gate line direction can be eliminated by an apparent crosstalk correction of less than one grayscale.

Abstract: A liquid crystal panel drive device performs overdrive by using a frame memory (1) and a lookup table (2). The device is characterized by that there are provided a plurality of types of lookup table (2) to be used according to temperature and the lookup tables (2) are selectively switched from one to another according to the information indicating the ambient temperature. The device is configured so as to have a hysteretic characteristic when the tables are switched from one to another according to the temperature information.
