Abstract:
1. A display device which corrects externally supplied video signals and displays said corrected externally-supplied video signals, said display device comprising: a display unit having a plurality of pixels disposed correspondingly to intersections of a plurality of scanning lines and a plurality of signal lines; a scanning driver which applies a scanning signal to said plurality of scanning lines; and a signal driver which applies display voltages to said plurality of signal lines, and said signal driver comprising: a first converter which converts a format of said externally supplied video signals into a first format; a memory which stores said video signals from said first converter temporarily and has a capacity for storing information on said plurality of pixels of said display unit; a correction circuit which computes correction values based upon said video signals from said first converter and said video signals stored in said memory and corrects said video signals from said first converter based upon said correction values; and a second converter which converts said first format of said video signals from said correction circuit to a format of said display voltages, wherein said memory stores said correction values also, and said correction circuit corrects said video signals stored in said memory based upon said correction values stored in said memory.
