Abstract
A graphic system which includes a display device having a graphic display area which includes a plurality of display portions and a plurality of one-chip semiconductor integrated circuit devices. Each one-chip semiconductor integrated circuit includes memory for storing a plurality of pixel data, each pixel data includes a plurality of bits and color data, and a logic circuit for carrying out logic operation on a unit of one pixel data read out from the memory based on a function signal supplied to the one-chip semiconductor integrated circuit device. The function signal indicates a relation between the unit of one pixel data read out from the memory and pixel data output by the logic circuit. The invention further includes an external device for supplying the function signal to the one-chip semiconductor integrated circuit device. The logic circuits, of the plurality of one-chip semiconductor integrated circuit devices, each carry out the same logic operation in accordance with the function signal. Further the logic circuit of the one-chip semiconductor integrated circuit device outputs pixel data based on the logic operation carried out by the logic circuit so as to display the p…
