ABSTRACT:
Output and/or perceived persistence of visible light from a cathode ray tube is improved by incorporating a UV-excitable phosphor into the screen, and by placing a UV-reflective filter on the inside of the display panel prior to formation of the phosphor screen, so that UV light emitted from the screen upon excitation by the tube's electron beam(s) is reflected back onto the screen to excite the further emission of visible light.
