    摘要: A colour cathode ray tube of the shadow mask or beam index type in which the screen structure applied to the faceplate (10) comprises a plurality of triplets of optical interference filter stripes (22) which are adapted to pass red (R), green (G) and blue (B) light produced by a homogeneous cathodoluminescent screen layer (24). The usual aluminium layer (26) may be applied to the screen layer (24). The optical interference filter stripes (22) may comprise short wave pass filters, band pass filters or a combination of both types. The short wave pass filter stripes may comprise modified quarter wavelength multi-­layer dielectric filters and the bandpass filter may comprise a Fabry-­Perot filter.

    摘要: A cathode ray tube having a black matrix phosphor screen. The cathode ray tube (1) has a film (4) composed chiefly of aluminum oxide which covers a carbon layer (3) of black matrix formed on the inner surface of a face plate (2). Phosphor layers (5R), (5G), (5B) are formed on the film (4). Therefore, the carbon layer, being very thin, does not burn white even in the step of baking. There is obtained a highly fine black matrix phosphor screen (6), making it possible to provide a very fine black matrix color cathode ray tube of good quality.

    摘要: A display tube comprising in an evacuated envelope (1) a display screen (7) provided on the inside of a display window (2) in the wall of the envelope (1), which display screen (7) comprises luminescent material (13), and a multilayer interference filter (12) is provided between this material and the display window and comprises a number of layers (HL) which alternately are manufactured from a material having a high (H) and a material having a low (L) refractive index. If the filter is composed substantially of 14 to 30 layers, each having an opical thickness nd, wherein n is the refractive index of the material and d is the thickness, which optical thickness is between 0.2λ f and 0.3λ f and preferably between 0.23λ f and 0.27λ f , wherein λ f is equal top xx, wherein λ is the desired central wavelength which is selected from the spectrum emitted by the luminescent material (13) and p is a number between 1.18 and 1.36, a display tube is obtained in which the luminous efficiency in the forward direction and at small angles for the central wavelength of the phosphor is at least 40% larger than in a tube without such a filter. Colour improvement and gain in contrast also occur.

    摘要: A cathode ray tube phosphor has the composition x(ZnO)Y 2 Si0 7 , 1≧x≧0.42 doped with at least one emitting ion. The emitting ion may be Mn 4+ or Eu 3+ to give a red emission; Mn 2+ orTb 3+ to give a blue emission. The phosphor (5) is coated on the inner face plate of a cathode ray tube (1). The coating may have different areas coated with different emitting ion to give a colour television tube. The tube may be used as part of an aircraft head up display.
