摘要
A method for use in the construction of a color display screen using deposition of a plurality of electroluminescent materials onto a substrate bearing said screen. The method comprises the forming operations a), b), and c) in any sequence: a) forming on the substrate a first pattern of deposition sites covered with a first material selectively strippable by a first agent; b) forming on the substrate a second pattern of deposition sites covered with a second material strippable by a second agent but not significantly attacked by said first agent; and c) forming on the substrate a matrix surrounding the first and second patterns of deposition sites. The method includes thereafter performing a first stripping of the first material with the first agent to reveal first deposition sites within the matrix and performing a first depositing of a first electroluminescent material within the first revealed deposition sites. Following the first stripping and depositing, the second material is stripped with the second agent to reveal second deposition sites within the matrix and a second electroluminescent material is deposited within the second revealed deposition sites. By the practice of the disclosed method the forming operations are segregated from the electroluminescent material depositing operations.
