Abstract: In a color picture tube apparatus having a first auxiliary deflecting means for deflecting a single electron beam, emitted from a cathode, in a direction to separate from the tube axis in synchronism with switching among a plurality of video signals supplied to an electron gun, and splitting the single electron beam substantially into a plurality of beam segments, and a second auxiliary deflecting means, disposed between the first auxiliary deflecting means and a main deflecting unit, for deflecting the plurality of beam segments in a direction to come close to the tube axis, the first auxiliary deflecting means is constituted by an electrostatic deflecting lens provided to an accelerating electrode system between a control electrode and a focusing electrode of the electron gun, and the second auxiliary deflecting means is constituted by a main electron lens of the electron gun for finally focusing the electron beam segments on a phosphor screen. Accordingly, the entire length of the picture tube can be shortened, and the auxiliary deflecting power can be reduced as well as the manufacturing cost.

Abstract: A color cathode ray tube employs a shadowmask having substantially vertical slots positioned between a single electron gun and substantially vertical color phosphor stripes on the faceplate of the tube. Piezoelectric bimorph actuators translate the shadowmask back and forth in a direction generally perpendicular to the direction of the slots and stripes in synchronization with field sequential color information to excite the phosphor stripes. In an alternative embodiment, the phosphor screen is moved relative to a fixed shadowmask. During the relative movement between the shadowmask and screen in a first direction, video information is provided from a memory in a first sequential manner, while for relative movement in a second direction, the video information is read out of memory in a reverse direction for executing a reverse raster starting from the bottom of the screen. The slots and phosphor stripes are skewed slightly with respect to one another to maintain proper color registration. In a further embodiment, instead of a shadowmask, a gating array is located between a broad source of electrons and the phosphor screen.

Abstract: This disclosure depicts, in a color cathode ray tube, the combination comprising an approximately rectangular, flangeless, curved faceplate supporting on a concave inner surface thereof in a central region a phosphor screen comprising a pattern of red-emissive, blue-emissive and green-emissive phosphor triads. A low mass, approximately rectangular, non-self-rigid shadow mask has a central portion with a pattern of electron-transmissive apertures registered with the pattern of phosphor triads. The mask has a rim portion providing substantial rigidity with respect to axes normal to the sides thereof while providing for flexure of the mask with respect to its diagonals. A mask suspension system for establishing a predetermined position of the mask relative to and at a predetermined spacing from the inner surface of the faceplate includes four suspension means for mechanically coupling the mask directly to corner portions of the faceplate. The suspension means are located one at each corner of the mask to permit the mask to flex about its diagonals and conform to the contour of the faceplate despite any twist-wise deformation thereof, thereby maintaining said predetermined spacing between the mask and the faceplate inner surface.

Abstract: The invention relates to novel cathode-ray/vacuum tubes for color television. It was found that the present color television tubes emit considerable amount of X-radiation. The novel tubes described below are characterized by the X-ray absorbing faceplate which prevents the escape of such X-radiation or at least reduces the amount of said escaping X-radiation to the level which is safe for the public. These tubes have a construction in which their light transparent endwall on which the fluorescent screen is mounted has the X-ray absorbing power to accomplish this objective, which means to reduce the transmission of X-ray through said endwall to the amount smaller than 0.04 mr./hr. in addition the faceplate of said tubes is provided with a light partially absorbing material which means light filtering material to improve the contrast of images produced by said tubes.
