Title:
LIGHT BEAM DISPLAY WITH INTERLACED LIGHT BEAM SCANNING
Document Type and Number:
WIPO Patent Application WO2002057838
Kind Code:
A3
Abstract:
A light beam display employing interlaced light beam scanning comprising a display screen (206) having a vertical and a horizontal dimension, a source of a plurality of light beams (200, 300) and an optical path including a movable reflector (32) having a plurality of reflective facets (34) between the display screen (206) and the light beam source. The movable reflector (32) directs the plural light beams (202, 302) to the display screen (206) via one or more facets of the movable reflector (32) to simultaneously illuminate plural different scan lines of the display which are spaced apart by plural non-illuminated scan lines. An optical mechanical element (216, 316) is provided for vertically shifting the light beams so as to illuminate different scan lines of the display screen.
