Abstract

A short throw ratio projection display system that produces high-resolution and high-dynamic range images. The system comprising a scanning laser for generating a light beam optically modulated with image information. The system further includes an image plane, in light of sight of the light beam, the image plane coated with an image-enhancing layer on a first side and a layer of fluorescent material strips on a second side. The image plane generates an image corresponding to the image information by absorbing the light beam and emitting visible fluorescent light corresponding to the intensity of the light beam falling on the fluorescent material.

Claims
