Title: Screen and projector used for front projector
Inventor: IAN AREKISANDAA SHIYANKUSU
IPC: H04N9/31
Filed: 1990-10-05
Abstract: PURPOSE: To increase the contrast of videos to ambient light by providing a screen with sections which reflect light of a prescribed wavelength range and reflect only slightly the light off the prescribed wavelength range. CONSTITUTION: The reflective screen 2 has six dichromatic layers 2Rr to 2Lb contg. cholesteric liquid crystalline materials. The layers of these cholesteric liquid crystalline materials reflect the light having the wavelength in the prescribed narrow wavelength range consisting of circularly polarized light having a prescribed direction. The projector 4 has three light sources 4r, 4g, 4b which respectively reflect the light having the wavelengths of the spectral bands reflected by the screen 2. Consequently, the light having the wavelength off the prescribed wavelength range preferentially transmits the screen 2. Then, when the ambient light, like daylight or artificial light having a wide wavelength band, is projected to the screen 2, the greater part of this light transmits the screen 2 without reflection and only the light of a relatively small ratio is reflected.  As a result, the contrast of the videos is increased.
