    Abstract: An efficiently cooled display tube is obtained by pumping a low viscosity liquid having a high heat capacity through a cooling space less than 1 mm. thick on the outside of the display window. A chamber is smoothly connected to the inlet aperture of the cooling space to assure a laminar flow, eliminating swirls which could give rise to refractive patterns in the display picture.

    Abstract: In a cathode ray tube including deflection coils for deflecting an electron beam produced in the tube by an electron gun, the center of the electron gun's focusing lens is positioned to coincide with the deflection point of the deflection coils. This positioning compensates for curvature of the deflection field.

    Abstract: A display tube comprising in an evacuated envelope (1) an electron gun system (6) for generating and focusing by means of a focusing lens at least two electron beams (28 to 35) on a display screen (5), which electron beams are deflected by deflection means and describe a frame on the display screen. The electron gun system (6) comprises at least two electron sources (20 to 26), the electrons in each electron beam being accelerated immediately after leaving the electron source by means of an electric field having a field strength exceeding 600 V/mm. The central axes (36) of the electron beam extend substantially parallel to each other, and all beams are converged by the focusing lens in the immediate proximity of the focus of the focusing lens, after which each separate beam is focused on the display screen by the focusing lens to form a spot. The astigmatism and the coma of the focusing lens, especially for objects not situated on the tube axis, decreases rapidly with decreasing object potential with the beam aperture angle being kept the same. The electrons leave the source at a low potential and are then accelerated in a strong electric field exceeding 600 V/mm nearly immediately after leaving the electron source, thereby effecting production of a very narrow electron beam which remains narrow up to the display screen. The effect of the field curvature of the focusing lens is also considerably reduced by the narrow beams. If all electron beams through the focusing lens converge in the immediate proximity of the focus of the focusing lens, a minimum of aberrations as a result of the deflection is obtained. The electron sources are preferably P-N cathodes or diode type electron guns.

    Abstract: 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 compises 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 optical thickness nd, wherein n is the refractive index of the material and d is the thickness, which optical thickness is between 0.2 .lambda..sub.f and 0.3 .lambda..sub.f and preferably between 0.23 .lambda..sub.f and 0.27 .lambda..sub.f, wherein .lambda..sub.f is equal to p x .lambda., wherein .lambda. 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. Color improvement and gain in contrast also occur.
