Our newly developed ultra-short throw distance laser light source projector is composed of triple rod illumination optics, mirror-lens hybrid ultra-wide angle projection optics and laser color processing. This projector has achieved the highest brightness of 7,000lm, the shortest throw distance of 60 cm at 100-inch image size and wider color gamut of 190% compared with sRGB by making full use of the advantages of laser such as high luminance, small etendue and high color purity. These specifications improve the visibility, convenience of installation and vividness of the image. In this paper, we describe our original developed technology such as the triple-rod illumination optical system, ultra-short projection optical system and laser color processing.
