摘要： An electron-optical device comprising a cathode ray tube with an envelope comprising an electron gun for producing an electron beam, whose inner surface carries a multi-element layer electrode such as a helical structure formed from a high-ohmic resistance material, which structure constitutes a focusing lens. A deflection system is used for moving the focused electron beam across a laser crystal arranged in the tube. Due to the laser action of the crystal, a scanning laser is realized. The laser light leaves a window in the tube envelope. The window extends at an angle between 20.degree. and 60.degree. to the longitudinal axis of the tube which is parallel to the electron beam incident on the laser crystal. Used in, inter alia, projection tubes and electron beam-pumped lasers (for example, scanning lasers).

摘要： The present invention enlarges the effective display area of a CRT for projecting while maintaining the strength of the panel necessary to allow for normal usage without breaking. The inside portion of the effective display area inside the rectangular display area is of a predetermined radius, and protrudes inward, extending in all directions. The four corners of the display area are outside of the circular boundary line comprised of the standard thickness Tf. Non-display areas H which are outside the boundary line are flat or protuberant, and have a thickness greater than the standard thickness Tf. Accordingly, with the present invention, the effective display area A2 can be made larger than previous effective display areas A1 in the prior art, which could not extend beyond a border that included the four corners, while maintaining overall the necessary strength.

摘要： A high-efficiency cathodoluminescent screen for high-luminance cathode-ray tubes has a design which makes possible a considerable improvement of the luminance. The cathodoluminescent screen of the invention includes a glass substrate (11) carrying a luminescent screen (12) consisting of luminophor grains. According to a characteristic of the invention, an intermediate screen (15) is inserted between luminescent screen (12) and substrate (11), with the intermediate screen (15) having a refraction index n1 which is clearly greater than refraction index n0 of substrate (11). As a result of this arrangement, a considerable part of the light which penetrates intermediate layer (15) is reflected in the direction of luminescent layer (12), so that this light can then be rediffused to substrate (11), i.e., to use, with an emission indicatrix which is much more greatly concentrated on the axis than in the prior art.

摘要： Phosphors used in colour cathode ray tubes, particularly but not exclusively projection television tubes, have colour point standards or chromaticities modified to conform to European Broadcasting Union (EBU) standards by disposing an interference filter in the light-path from the phosphor, for example, between the phosphor and the faceplate, which has a peak gain greater than unity over a selected part of the frequency spectrum. As a result, an efficient broadband phosphor can be employed to obtain the desired chromaticity and thereby increase the white-D luminance of projection television systems.
