Deposition of cathodoluminescent materials by reversal toning

摘要

A method for the deposition of phosphor containing materials to CRT or VFD faceplates using reversal toning is dislosed. The method incudes the steps of charging the phosphor containing particles and the surface of a patterned photoresist with a charge of the same sign so that the particles are accurately deposited directly to an uncharged transparent surface electrode on the substrate. In a preferred embodiment, glass and/or polymeric binders may be included with the phosphor containing materials to enhance adherence to the substrate.
