Surface Plasmon High Efficiency Hdtv Projector
US Patent:
5570139, Oct 29, 1996
Filed:
May 13, 1994
Appl. No.:
8/242628
Inventors:

International Classification:
H04N 931, H04N 574

Abstract:
A surface plasmon high efficiency HDTV projector employs voltage-induced color-selective absorption with surface plasmons at metal/liquid crystal interface. When a collimated p-polarized white light (9) is incident at metal (2) and liquid crystal (6) interface, surface plasmon resonance can be excited, certain frequencies of photons will be absorbed without reflection, and the reflected light shows the complementary color. This resonance frequency depends on the dielectric constant of both the metal film and the liquid crystal. If a voltage (8) is applied on the liquid crystal (6) to change its dielectric constant, then the absorption spectrum can be controlled by this voltage. When the p-polarized white light is reflected three times at three interfaces which are set a surface plasmon resonance at blue, green and red respectively, any color can be generated by switching these resonances. Because this device only takes the unwanted colors out of the spectrum, the wanted color almost all pass through, the optical efficiency of this device is very high.
