Abstract:
A multi-layer coating for the outer surface of a display screen of a self-emitting display device, wherein said display screen further includes a phosphor coating on an inner surface thereof, and wherein said phosphor coating is responsive to energetic electrons incident thereon for providing a video image, said coating comprising:an inner antistatic layer disposed on the outer surface of the display screen and having a first refractive index n1, wherein said inner antistatic layer includes electrically conductive particles having a high specific surface area and a surface activation agent to disperse said conductive particles in said inner antistatic layer; an outer antireflective layer disposed on said inner antistatic layer and having a second refractive index n2, where n1&gE;n2, and wherein said outer antireflective layer includes silica; and a high light refractive material added to said inner antistatic layer to increase the refractive index n1 of said inner antistatic layer and reduce light reflection from the display screen, wherein said high light refractive material is from the group comprising ZrO2, ZnO and ZnS.
