摘要：The present invention relates to field of projection type video image displaydevices to allow the method that color adjusts, such color adjusts. The device includesthe luminous flux of light source (1) transmitting white light; Color (2a feeding-distribution device means, 2b) is used to for white light to be divided into red three basiccoloured light, blue and green light; Light valve (3R 3G, the 3B for modulation light) isincluded in light beam from the color (2a feeding-distribution device means, 2b),
generates video image; The selective means of color (4) are for combining the light beammodulated and the projection of projecting optical device (5) beam combination on thescreen. Airtight petite person's dichroic filter (10,10a, 10b, 10c) has characteristic any oneoptionally through being inserted into the optical path of the white light luminous fluxand being taken out with selectively reflecting red, blue or green light and be at leastpartially arranged in, and provides the luminous flux for combining color.
