ABSTRACT:
A method for improving the adherence of a phosphor screen to the face panel of a color cathode ray tube involves 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 form which the light emerged, thereby effectively increasing the exposure dosage of those areas.
