Abstract:
For use on a flat outer surface of a glass display screen of a self-emitting display device, wherein said glass display screen further includes a concave inner surface with a phosphor coating thereon, wherein light transmission through the display screen varies with the thickness of the display screen and the display screen has a high light transmission characteristic, and wherein said phosphor coating is responsive to energetic electrons incident thereon for providing a video image, a coating comprising:a first inner electrically conductive antistatic layer disposed on the flat outer surface of the glass display screen and including carbon black particles, wherein light transmission through said first inner antistatic layer is adjustable by varying the concentration of said carbon black particles for providing substantially uniform light transmission of the video image through the display screen and first antistatic layer over the entire surface of the display screen, wherein said first inner antistatic coating further includes indium-doped tin oxide particles with the weight ratio of said carbon black particles to said indium-doped tin oxide particles being in the range of 31%-50%; and a second outer antireflective layer disposed on said first inner antistatic layer and having a low light refractive index.
