摘要:
A method for manufacturing an anti-reflection film of a display device comprises steps of forming a first layer (2) which is an electrically-conductive thin film having a first refractive index, and which is deposited on an outer surface of a glass face panel (1), forming a second layer (3) which is a thin film having a second refractive index lower than said first refractive index, and which is deposited on an outer surface of said first layer (2), and forming a third layer (4) which is deposited on said second layer (3), and which has a large number of concave regions (6) each surrounded by convex regions (5) on an exposed surface of said display device. According to the invention said first layer (2), said second layer (3) and said third layer (4) form said antireflection film which has a luminous reflectance of 1.5% or less, and a reflectance of 3% or less between the wavelength of 436 nm and 700 nm.
摘要:
On the outer surface of a glass face panel 1 of a display device, a first layer 2 of an electrically conductive transparent thin film having a high refractive index, and a second layer 3 and a third layer 4 having a low refractive index are deposited as an anti-reflection film. The first layer 2 is formed to have a thickness in a range of 10 --- 20 nm, whereby the surface of the anti-reflection film has a luminous reflectance of 1.5% or less, and a reflectance of 3% or less at a wavelength of 436 nm most prominent light of blue.

摘要:
On the outer surface of the glass face panel 2 of a display device, a first layer 5 of an electrically conductive transparent thin film, a second layer 6 of another transparent thin film consisting essentially of silicon dioxide (SiO₂) or magnesium fluoride (MgF₂), and a third layer 7 of uneven exposed surface, are deposited, whereby a multiplicity of concave regions of said third layer 7 form an interference film together with said first 5 and second layer 6, whereas a multiplicity of convex regions of said third layer form an irregular reflection surface.
摘要:
A color image receiving tube comprising three color (red,green and blue) phosphor screens (6R, 6G, 6B) on an inner surface of a face-plate 4; wherein at least two of said three color phosphor screens are coated with pigments(7R, 7G, 7B); and wherein said three color phosphor screens have a total reflective brightness less than 70% that of three color phosphor screens with no pigment coating. According to the above-mentioned constitution, a color image receiving tube having a higher emisson brightness and contrast is achieved as compared to a color image receiving tube having the same reflective brightness, where the reflective brightness is obtained by lowering the light transmittance of its face-plate.
