Process for preparing high resolution emissive arrays and corresponding articles

Abstract

A process is described for forming an emissive or phosphor screen. The process comprises the steps of: a) providing a thermal mass donor element comprising a substrate with a front side and a back side, with a coating of emissive material or phosphor adhered to said front side of said substrate, b) placing said coating of emissive material or phosphor adjacent to a support layer, c) addressing said mass donor element with coherent radiation to heat at least a portion of said coating of emissive material or phosphor to locally transfer at least some of said emissive material or phosphor to said support layer, d) repeating step c) a sufficient number of times to provide a coating of transferred emissive material or phosphor on said support layer in an area of at least 1 square centimeter.
