FIELD: TV equipment. SUBSTANCE: device has white light source, multiple dichroic mirrors which split light beam into three beams of basic colors which are reflected by three alternating-shape surfaces which reflect beams through slits in non-reflecting surface. This results in modulation of light beam intensity. Light which passes through slits is scanned in horizontal direction by means of one surface of rotating polygon mirror. Then light is passed through collimating lenses and projected on screen. EFFECT: increased functional capabilities. 46 cl, 5 dwg
