Luminescent screen with mask layer

摘要

The present invention provides luminescent screens with a mask layer, methods of manufacturing the screens, and display devices incorporating the screens. The mask layer is attached to a matrix defining the pixels in the screen and preferably includes voids formed therethrough corresponding to each pixel. The voids in the mask layer preferably have a size generally corresponding to that of the pixels near the phosphor material and narrow in the direction of the electron source.
