Surface plasmon high-efficiency projection display

A novel projection display, based on a new phenomenon of voltage-induced color-selective absorption with surface plasmons, is able to generate bright image on a large screen with high efficiency. In addition, neither color filter nor phosphor is needed to generate the color. With an incident beam of +/- 7 degrees half cone angle, the color purity of this device can be as good as the CRT displays, and the contrast ratio can reach over 200:1. System analysis shows that, for a color sequential single panel 1.8 inches surface plasmon projector, the luminous efficiency can reach 3 Lumens/Watt, and for a 1.8 inches surface plasmon 'smart card' projector, the luminous efficiency can reach over 10 Lumens/Watt.
