摘要： A mask assembly for a cathode ray tube includes a shadow mask for permitting electron beam to strike phosphor elements associated with the beam, a frame for supporting the shadow mask, and an electron beam interceptor which selectively passes electron beam and is mounted on the frame and between the shadow mask and an electron gun of the cathode ray tube. The electron beam interceptor is a metal sheet and includes a blocking mask on which a plurality of apertures are formed at the positions which correspond to the apertures of the shadow mask, and one or more supporter whose ends are adhered at the frame and the blocking mask to support the blocking mask in a funnel of the CRT.

摘要： Disclosed are a shadow mask, a cathode ray tube having the above shadow mask and a method for manufacturing a screen using the shadow mask. The shadow mask can concentrate electron beams and thereby largely increase luminance even with low electric power without deteriorating the purity of colors. The shadow mask has a first and a second thin metal plates. A first and a second voltages are applied to the first and the second thin metal plates and concentrate the electron beams passing through the first and the second electron beam passing holes respectively formed in the metal plates. The screen is manufactured with a controlled size of a developed area by controlling time using the shadow mask and an electrophotographical process.

摘要： In a color cathode ray tube, a single selectron beam is deflected through a deflection yoke and passes through a collimation lens to an active shadow mask formed with a plurality of apertures to divide the beam into a plurality of segments. Each beam segment is intensity modulated at the entrance of its aperture through modulating electrodes which focus the electrons in the beams at crossover points within the apertures. Lens electrodes at the exits of the apertures restore travel of the electrons to parallel paths approaching a three color phosphor screen. The distance between corresponding modulating and lens electrodes at the entrance and exit of each aperture is approximately equal to the sum of the focal lengths thereof for restoring said electron travel to the parallel paths and thereby correctively regulating display of multi-color information on the screen corresponding to the input modulating voltage signals applied to the modulating electrodes.

摘要： A method of manufacturing a color display tube having a magnetic quadrupole post-focusing mask, in which the mask is magnetized by magnetic field shaping means of soft iron, or the magnetic equivalent, having raised portions, for example strips placed against opposite sides of the mask sheet and subjected to an external strong magnetic field by an electromagnet to induce magnetic poles through the thickness of the mask sheet. The geometric arrangement of the raised portions of the field shaping means is such that cyclically a north pole, a south pole, a north pole and a south pole are induced into the sheet material surrounding each aperture. Using this technique, the entire area of a mask sheet can be magnetized in one operation. Also masks for small tubes and high definition tubes can be made.
