摘要:
A high definition display apparatus having a wavelength selective absorption effect and an anti-static and anti-reflection effect is provided by thin films having a low resistance and a high refractive index. The high definition display apparatus has an anti-static and anti-reflection film composed of laminated oxide or metallic thin films, wherein at least three layers of oxide or metallic films having different reflectance from each other are laminated onto the front surf ace of the display apparatus, and the laminated films are composed such that an absorbing film containing coloring material is arranged under a high reflectance film as seen from the outer surface of the laminated films.

A display device includes a first substrate, a second substrate disposed to face the first substrate, plural pixels disposed in a display area on an inner surface of the first substrate, a rubber member disposed between the first and second substrates to surround the display area, and sealing the display area from an ambient atmosphere, and an adhesive layer sealing together the first and second substrates along peripheries thereof. The adhesive layer is derived from a sol-gel solution.

A cathode ray tube includes a film which is formed on an outer surface of a panel portion. The film is comprised of a first particles which become transparent due to the oxidation and a second particles which are chemically and physically stable and have the light absorbing ability and the conductivity. A number of the transparent first particles is gradually increased toward a peripheral portion from the center portion of the panel portion.
摘要:
A cathode ray tube has a metal film formed to cover phosphor areas of a phosphor layer on an inner wall of a panel portion of an envelope. The metal film is formed over an organic film resin applied to the phosphor layer, the organic film resin is baked and removed so that the metal film covers the phosphor layer, and cracks are formed in the metal film in a greater number on side portions of the phosphor areas than on an upper portion of the phosphor areas. This construction results in a cathode ray tube with a metal film that can prevent a blister phenomenon and a reduction in brightness.

There is provided a field leakage preventing coating for a cathode ray tube, including a vacuum envelope having a panel section, a neck section and a funnel section connecting the panel section and the neck section; a fluorescent film applied on an inner face of the panel section; and an electron gun, mounted in the neck section, for emitting three electron beams toward the fluorescent film. The field leakage preventing coating is formed by adhering a double coating film composed of a conductive first layer mainly composed of particles of one or more kinds of metal among noble metal elements of gold (Au), silver (Ag) and platinum (Pt) and a second layer mainly composed of silicon dioxide (SiO2) or magnesium fluoride (MgF2) on an outer face of a faceplate of a panel section of the color cathode ray tube.

A cathode ray tube has a panel portion 1 with a phosphor layer 5 formed on its inner face, a neck portion 2 accommodating an electron gun 9, a funnel portion 2 for coupling the panel portion 1 to the neck portion 2 and a color selective electrode assembly 6 having a number of electron beam passing openings arranged opposite to the phosphor layer 5 with a space therebetween. The color selective electrode assembly is installed within the panel portion 1. An electron beam reflection film of a bismuth oxide thin film 6R having a bulk density of from 4 to 9.3 g/cm.sup.3 is formed on the face of the color selective electrode assembly 6 against which the electron beams 14 emitted from the electron gun 9 collide. The cathode ray tube is capable of displaying high density and high resolution image.

摘要:
An exposure method and apparatus for forming phosphor stripes or black matrix stripes on the inner surface of a face plate of a stripe phosphor screen type color picture tube or CRT (cathode-ray tube), in which a single linear light source is used as the exposure light source, and a prism device including many juxtaposed prisms is disposed between the linear light source and the face plate. The taper angle of the prisms is continuously changed so that the single linear light source can be observed as a plurality of discontinuous virtual linear light sources at whatever point on the inner surface of the face plate, and the virtual linear light sources have a most suitable center-to-center distance at individual positions on the face plate. The above arrangement eliminates the necessity for drive means for moving the linear light source, and a phosphor screen having three color phosphor stripes of satisfactorily uniform width can be formed on the entire inner surface of the face plate with use of the single linear light source.
