Abstract (en)

[origin: WO9524728A1] Adherence of the phosphor screen to the face panel of a colour cathode ray tube is improved by placing a UV-reflective filter on the inside of the face panel prior to photolithographic forming of the screen, in order to reflect transmitted UV light back onto those areas from which the light emerged, thereby effectively increasing the exposure dosage of those areas.
