ABSTRACT:
To reduce reflection at a surface of a cathode ray tube display window, the surface is provided with a pattern of irregularities formed by ultraviolet laser radiation. Preferably the inside surface of the display window of the cathode ray tube is treated with the pattern of irregularities followed by a phosphor pattern over the treated surface. In one embodiment, a transmission grating is used to pass ultraviolet radiation to form the irregularities.
