Abstract
A viewing surface capable of high contrast and high resolution comprising one or more materials that preferentially reflect or transmit or scatter monochromatic light at the primary wavelengths necessary to generate the color gamut appropriate for a given display application. A viewing surface capable of high contrast and high resolution comprising one or more materials which can include rare earth ions, etc. and may be combined with absorbing substrates and/or interference filters.
Claims31
A viewing screen comprising:
- a passive screen;
- said screen absorbing ambient light;
- and
- said screen including a rare earth containing material, the rare earth containing material adapted to preferentially select light in a narrow wavelength region from a substantially monochromatic source.
A viewing screen comprising:
- a passive screen that absorbs ambient radiation;
- and
- said screen including a rare earth containing material adapted to preferentially select substantially monochromatic radiation from a substantially monochromatic source.
A viewing screen comprising:
- a passive screen including a rare earth containing material that preferentially selects substantially monochromatic radiation.
A viewing screen comprising:
- a passive screen;
- said passive screen absorbing ambient light;
- and
- said passive screen including a transition metal containing material adapted to select a primary color of substantially a single wavelength from a substantially monochromatic source.
A viewing screen comprising:
- a passive screen;
- said passive screen absorbing ambient radiation;
- and
- said passive screen including a transition metal containing material that can preferentially select radiation of substantially a single wavelength from a substantially monochromatic source.
A viewing screen comprising:
- a passive screen including a transition metal containing material that can select light of substantially a single wavelength.
