Abstract

An image generation system is provided. A display matrix (12) is provided and has a plurality of display elements (14) which can include liquid crystal. Each display element (14) includes a pixel (16). A plurality of display circuits (18) are electrically connected to a display element. A plurality of memory cells (20A, 20B) are associated with each of the circuit. A selector (21) is used to select the pixel data from one memory cell at a time.
