Abstract (en)
A method of producing a phosphor screen for a colour cathode ray tube in which the adherence of the phosphor screen to the face plate panel (11) of a colour cathode ray tube envelope (50) is improved by placing a retroreflective surface (50) opposite the face plate panel (11) during photolithographic forming of the screen in order to reflect transmitted light back onto those areas from which the light emerged, thereby effectively increasing the exposure of those areas.
