Abstract

A display apparatus includes first and second IR or other light sources (80) that produce light at respective first and second non-visible wavelengths. The light is modulated according to a desired image. The modulated light (82) is then applied to a wavelength selective phosphor (96) that converts each component of the light to a respective visible wavelength. In one embodiment, the image source is a scanned light beam display (70) that scans an IR light beam onto a screen that carries the phosphor.
