    Abstract: Image intensifiers may include a photocathode that emits photoelectrons in proportion to the rate photons impact the photocathode. The photoelectrons are multiplied using a microchannel plate that includes a plurality of microchannels. Photoelectrons are scattered by the microchannel plate when the photoelectrons strike the surface of the microchannel plate rather than enter one of the microchannels. Electron scatter within an image intensifier results in a halo or bloom around bright or luminous objects. Halo or bloom may be minimized by reducing the electron scatter within the image intensifier. Deposition of an anti-scattering layer on the surface of the microchannel plate within the image intensifier can absorb photoelectrons that fail to enter a microchannel and may thus reduce the incidence of halo or bloom.

    Abstract: In a cathode ray tube including a panel provided with a phosphor screen, a funnel integrated with the panel, an electron gun disposed inside the funnel, a magnetic shield (1) for shielding an electron beam (5) emitted from the electron gun against an external magnetic field, and a frame (2) for holding the magnetic shield (1), the magnetic shield (1) includes, at a portion to be joined with the frame (2), a bent portion (20) bent toward a tube axis side, and a thickness T of the bent portion (20) at its edge on the tube axis side is 0.08 mm or less. By making the thickness T small, halation that is liable to occur in a cathode ray tube with a large deflection angle can be suppressed because electron beams reflected from an end face (11) and allowed to reach the screen without being shielded by the frame (2) are reduced.

    Abstract: A pixel for a display device has a shape outlined by a black matrix or a barrier. The pixel is shaped with a polygon having 2(n+1) angled portions where n is a natural number of 2 or more. Such a pixel may be also processed without a previously formed black matrix.

    Abstract: A color cathode ray tube is disclosed, that comprises an optical filter layer 2 formed on an inner surface of a glass panel 1, a thin film formed on a front surface of the optical filter layer 2 and composed of a metal oxide, and a fluorescent substance layer 4 formed on the thin film 3 corresponding to a pattern of the optical filter layer 2. The surface state of the thin film 3 is rougher than the surface state of the optical filter layer 2 and similar to the surface state of the fluorescent substance layer 4. Thus, the optical filter layer 2 sparsely contacts the fluorescent substance layer 4. Thus, the influence of the optical filter layer 2 to the fluorescent substance layer 4 can be reduced. Consequently, fluorescent substance particles of the fluorescent substance layer 4 can be suppressed from breaking, dropping, and so forth. Thus, an excellent fluorescent surface can be obtained at high throughput.
