ELECTROGRAPHIC METHOD OF MANUFACTURE OF LUMINESCENT SCREEN UNIT ON BACKING OF COLOR CATHODE-RAY TUBE AND LUMINESCENT SCREEN UNIT ON INNER SURFACE OF FRONTAL PANEL OF COLOR CATHODE-RAY TUBE Russian patent published in 1995 - IPC

FIELD: radio engineering. SUBSTANCE: electrographic method of manufacture of luminescent screen unit on backing of cathode-ray tube involves stages of formation of layer of nonluminescent material of screen structure and of assemblage of materials (G.B.R) of screen structure having color glow on backing by method of dry electrography. These material of screen structure having color glow are surrounded by mentioned materials. Electrostatically changed dry powdery resin which melts to form practically continuous film is deposited over these materials having color glow and nonluminescent material layer. EFFECT: facilitated manufacture. 13 cl, 9 dwg
