ABSTRACT:
An apparatus for electrophotographically manufacturing a luminescent screen assembly on a substrate for use within a CRT includes a developer for developing a photoconductive layer, having a latent image thereon, with a dry-powdered, triboelectrially-charged screen structure materials. The photoconductive layer overlies a conductive layer in contact with the substrate. A grid-developing electrode is located at a distance from the photoconductive layer that is large relative to the smallest dimension of the latent image. The electrode is biased with a suitable potential to influence the deposition of the charged screen structure materials onto the latent image on the photoconductive layer. A method for electrophotographically manufacturing the screen assembly utilizing the grid-developing electrode is also disclosed.
