Abstract:
A light source for a digital image projection system, comprising a thin-film resonant microchamber with an active phosphorus area arranged between a front and a rear film reflector and an electron source for generation of an image-like structure for stimulation of the phosphorus, the electron source comprises a primary electro-luminescent image-generating unit having a layer of electro-luminescent phosphorus and an array of control electrodes for generation of a front luminescent image in the electro-luminescent phosphorus layer; and an image amplifier with a photocathode arranged adjacent to the electro-luminescent phosphorus layer for the generation of electrons as a result of light from the primary electro-luminescent image and an anode for acceleration of the generated electrons by a voltage difference in the direction of the thin-film resonant microchamber.
