Abstract: A CRT 10 has an evacuated envelope 11 comprising a funnel 15 having a neck 14 and an open end. The funnel 15 is sealed at the open end to a faceplate panel 12 having a luminescent screen 22 formed on a viewing area of an interior surface of the faceplate panel by an electrophotographic screening process. The screen 22 comprises a multiplicity of different color-emitting phosphor elements. A light absorbing matrix 23 has a first portion that includes a multiplicity of openings therein overlying the viewing area of the faceplate panel, and a second portion providing an imperforate border 123 extending beyond the viewing area. The phosphor elements are disposed within the openings in the matrix. A color selection electrode 25 is mounted within the faceplate panel 12, in proximity to the screen 22. An electron gun 26 is centrally disposed within the neck 14 for generating and directing a plurality of electron beams 28 toward the screen 22. The screen structure is improved by having at least one of the phospor elements disposed on the imperforate border 123 of the matrix 23.

Abstract: A CRT (10) HAS AN EVACUATED ENVELOPE (11) COMPRISING A FUNNEL (15) HAVING A NECK (14) AND AN OPEN END. THE FUNNEL (15) IS SEALED AT THE OPEN END TO A FACEPLATE PANEL (12) HAVING A LUMINESCENT SCREEN (22) FORMED ON A VIEWING AREA OF AN INTERIOR SURFACE OF THE FACEPLATE PANEL BY AN ELECTROPHOTOGRAPHIC SCREENING PROCESS. THE SCREEN (22) COMPRISES A MULTIPLICITY OF DIFFERENT COLOR-EMITTING PHOSPHOR ELEMENTS. A LIGHT ABSORBING MATRIX (23) HAS A FIRST PORTION THAT INCLUDES A MULTIPLICITY OF OPENINGS THEREIN OVERLYING THE VIEWING AREA OF THE FACEPLATE PANEL, AND A SECOND PORTION PROVIDING AN IMPERFORATE BORDER (123) EXTENDING BEYOND THE VIEWING AREA. THE PHOSPHOR ELEMENTS ARE DISPOSED WITHIN THE OPENINGS IN THE MATRIX. A COLOR SELECTION ELECTRODE (25) IS MOUNTED WITHIN THE FACEPLATE PANEL (12), IN PROXIMITY TO THE SCREEN (22). AN ELECTRON GUN (26) IS CENTRALLY DISPOSED WITHIN THE NECK (14) FOR GENERATING AND DIRECTING A PLURALITY OF ELECTRON BEAMS (28) TOWARD THE SCREEN (22). THE SCREEN STRUCTURE IS IMPROVED BY HAVING AT LEAST ONE OF THE PHOSPOR ELEMENTS DISPOSED ON THE IMPERFORATE BORDER (123) OF THE MATRIX (23).

Abstract: A method for developing an electrostatic latent charge image formed on a photoreceptor (36) which is disposed on an interior surface of a faceplate panel (12) of a CRT (10) utilizes a developer (40) having a developing chamber (42) with a sidewall (50) closed by a bottom end (44) and a panel support (46) at the other end. An opening (48) is formed through the panel support (46) to provide access to and support for the faceplate panel (12). A panel grid (74) is disposed in proximity to said interior surface of said faceplate panel (12) and operated at a first potential to control the electric field from the latent charge image. A tank grid (56) is disposed within said developer (40) and spaced from the sidewall (50), the bottom (44) and the panel grid (74). A triboelectric gun (84) is disposed within the developer (40) for imparting a desired charge polarity to the screen structure material and for distributing the charged screen structure material onto the latent charge image. An electrometer (66) and a phosphor deposition monitor (90) monitor the deposition of the charged screen structure material onto the latent charge image; and a controller (68) terminates the deposition of the charged screen structure material when sufficient material is deposited. The tank grid (56) is operated at a potential different from the potential on the panel grid (74) so that the tank grid (56) controls the electrostatic forces within the developer (40).
