Patent ID: 6933914

Claim:
A display signal supply apparatus for supplying display signals to an active matrix type image display device, comprising: a distributing circuit for distributing the display signals input thereto from an outside into a first signal and a second signal; a first storage area for storing said first signal obtained by distributing the display signals by said distributing circuit; a second storage area for storing said second signal obtained by distributing the display signals by said distributing circuit; and a signal outputting circuit for instructing an output of said first signal front said first storage area prior to storing said entire first signal in said first storage area; and wherein said signal outputting circuit instructs an output of said second signal stored in said second storage area from said second storage area after said first signal in specified amount is output from said first storage area; said distributing circuit distributes display signals for m number of pixels into the first signal for m/2 number of pixels and the second signal for the m/2 number of pixels, the signals being input from the outside, and said signal outputting circuit instructs the output of the priorly stored first signal from said first storage area when the first signal for m/4 number of pixels is stored in said first storage area, and instructs the output of said second signal stored in said second storage area from said second storage area after the first signal for the m/2 number of pixels is output from said first storage area.
