Abstract:
An electrically conductive coating for an outer surface of a glass display screen of a self-emitting display device, wherein said glass 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:a thin layer of a solution of carbon black particles having a black appearance and disposed on the outer surface of the device's glass display screen; a blue additive dispersed in said carbon black solution to reduce absorbance of blue light by the carbon black and provide substantially uniform color absorption by said carbon black solution over the visible light spectrum, wherein said blue additive reduces the absorbance of light having a wavelength in the range of 400-500 nm and has a weight % relative to said carbon black particles of 5-60% and an antireflective layer disposed on said thin layer of carbon black solution.
