Abstract
An encapsulated matrix structure and formation method for preventing contamination caused by thermally induced outgassing and electron stimulated desorption of contaminants. In one embodiment, the present invention is comprised of a matrix structure which is adapted to be coupled to a faceplate of a flat panel display. The matrix structure is located on the faceplate so as to separate adjacent sub-pixel regions. The present embodiment further includes a contaminant prevention structure which covers the matrix structure. The contaminant prevention structure of the present embodiment has a physical structure such that contaminants originating within the matrix structure are confined therein. The contaminant prevention structure can also be designed to prevent electrons from impinging on the black matrix and desorbing contaminants. In so doing, the present invention prevents deleterious thermally induced outgassing and electron stimulated desorption of contaminants by the matrix structure.
