ABSTRACT:
A display device using laser comprises an input path for a composite video signal, a memory for storing the video signal by picture regions divided according to the size of picture, a controller for controlling the scanning position and the division of picture regions, a semiconductor laser for reading out R, G and B signals from the memory, and then scanning laser beams, and a scanning controller for controlling the path of a laser beam. The device displays an optical signal on a wall or large white surface without an additional cathode ray tube and adjusts screen size by controlling the distance between the device and the display surface.
