ABSTRACT:
A direct viewing picture image display apparatus displays a good picture image with a small amount of light and low power consumption using a laser beam without producing speckle noises. The display apparatus comprises a light source for emitting a laser beam, an optical modulating system for optically modulating the laser beam from the light source in response to a video signal, a scanning system for horizontally and vertically scanning the modulated laser beam from the scanning signal in response to a scanning signal, and a projecting optical system for projecting the scanned laser beam from the scanning system to form an image of the laser beam on the retina of an eye of an observer. Depth information is provided to the laser beam at a suitable stage after optical modulation by the optical modulating system so that a stereoscopic image is displayed.
