METHOD FOR ELECTROPHOTOGRAPHIC MANUFACTURE OF LUMINESCENT SCREEN STRUCTURE ON SUBSTRATE TO BE USED IN CATHODE-RAY TUBES Russian patent published in 1994 - IPC

Abstract RU 2020637 C1

FIELD: electronic engineering. SUBSTANCE: method involves sequential coating of substrate by electricity conducting layer and application of photoconducting layer on it, setting of electrostatic charge on photoconducting layer and exposure of random areas of photoconducting layer to visible light for inducing charge in it. Then photoconducting layer is developed by charged screen structural material in the form of dry powder incorporating at least check agent of surface charge to control triboelectric charge of screen structural material. EFFECT: facilitated procedure. 11 dwg
