Abstract:
A method for applying an antistatic/antireflective coating to an outer surface of a glass display screen of a CRT, wherein a video image is produced on the glass display panel by plural electron beams incident upon a light emitting coating disposed on an inner surface of said glass display screen, and wherein an electrostatic charge is produced on said display screen by said electron beams incident thereon and incident light is reflected by said display screen, said method comprising the steps of:applying an electrically conductive antistatic layer by sputtering to the outer surface of the glass display screen; masking a peripheral portion of said antistatic layer; and applying an insulative antireflective layer on said antistatic layer by sputtering, wherein said antireflective layer is not disposed on the masked portion of said antistatic layer leaving the masked portion of said antistatic layer exposed for connection to an electrically grounded conductor for directing electrostatic charge on the display screen to neutral ground.
