PROJECTION-TYPE DISPLAY DEVICE AND METHOD FOR CONTROLLING PROJECTION-TYPE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/155571
Kind Code:
A1
Abstract:
A color foil according to the present invention has a plurality of transmission regions (R, G, B, C, W, Y) on which light from a light source is incident, and through each of which is transmitted a different wavelength of light. A detection unit according to the present invention detects environment information. A power supply unit according to the present invention supplies electric power to the light source. A control unit according to the present invention controls supply power supplied by the power supply unit to the light source. The transmission regions (R, G, B, C, W, Y) on which the light from the light source is incident vary in sequence. When the environment information satisfies a predetermined condition, the control unit changes the supply power in synchrony with the plurality of transmission regions (R, G, B, C, W, Y).
