Abstract:
1. A projection-type display apparatus, comprising: a light source unit, configured to emit an excitation light onto a nearly point-like area of a reflecting surface including a light emitting substance, the reflecting surface configured to reflect the excitation light received from the light source unit and also to emit an emission light from the light emitting substance, such that a white color light originates from the nearly point-like light source on the reflecting surface; a light separation optic system, configured to receive the white color light that originates from the nearly point-like light source on the reflecting surface, and to separate the white color light into three primary color lights: red-color (R), green-color (G), and blue-color (B), and to emit the three primary color lights; R, G and B light modulating portions, each of which is configured to modulate a respective one of R, G and B polarized separated lights, depending on a video signal; a light composing unit, configured to compose optical images formed by the R, G and B light modulating portions; and a projecting portion, configured to project an enlarged version of the optical images.
