Abstract
A flat-panel display comprises a projector () illuminated by a collimate light source such as an infra-red laser, a waveguide () which ejects rays at a distance along the axis of propagation related to their angle of injection into the edge of the waveguide, an input slab () for magnifying the projected image in the width dimension in the plane of the panel perpendicular to the axis of propagation, and a phosphor output screen which converts the infra-red light to the visible. The use of monochromatic light within the waveguide reduces dispersion problems, and the use of a triad of projectors, each injecting at a different angle, makes registration relatively simple.
