IMAGE DISPLAY APPARATUS USING LIGHT PROJECTION

摘要

PURPOSE: A light projection type of an image display device is provided to output a projection image by using a first light source unit and a second light source unit which outputs light with a method which is different from the first light source unit. CONSTITUTION: A second light source unit(420) outputs light with a method which is different from a first light source unit(410). A color separation unit(430) successively separates color by receiving the light from the first light source unit. A light synthesizing unit(440) synthesizes the light by projecting the light which is separated from the color separation unit. An integrator(450) amplifies the light collected in a third collection lens(445). A projection lens(470) projects an image to the outside.
