Abstract: A color television picture tube of the single electron gun type includes an electron gun composed of a cathode for emitting electrons, control grids disposed in the neighborhood of said cathode, a first anode, and a set of electrodes constituting an electron lens for converging the electron beams emitted from said cathode. A plurality of phosphor dots of different colors are formed on the face of the tube. A shadow mask is disposed between said phosphor dots and said electron gun. An electron beam image is formed in the interior of said electron lens. Voltages on each electrode focuses the crossover point of the electron beams on the surface of said shadow-mask. By postdeflection focusing the beam at the shadow-mask is focused on said phosphor dots in positions corresponding to a plurality of portions of said electron beam.

Abstract: Color CRTs, used in large display screens, have a plurality of three color electron beams that are strongly focused so that they crossover and become divergent in both the X and Y axes of the CRT's face. The strength of the focusing determines the size of the illuminated area on the face of the CRT. A shadow mask, aperture grill, or slotted mask and the red, green and blue phosphor dots or stripes are located at predetermined positions such that the red electron beams only hit the red phosphors, the green electron beams only hit the green phosphors, and the blue electron beams only hit the blue phosphors. No raster scanning with the electron beams are required.

Abstract: A cathode ray tube device has multiple elements for generating a display. Each of the relatively large number of elements has its own electron gun and deflection assembly and a shadow mask. A large number of these subunits are connected into a regular array in which each unit generates a portion of the overall display. The individual elements are preferably formed in a framework which serves to both align and position the individual assemblies, and further to provide structural support for the evacuated tube.

Abstract: An evacuated envelope has a rectangular display section and a gun section at one edge of the display section. The display section includes front and back walls which are generally rectangular, in closely spaced, parallel relation, and a plurality of spaced, parallel support walls between the front and back walls forming a plurality of parallel channels. The gun section extends across one end of the channels and includes therein gun structure which will direct electrons into the channels. In each of the channels is a beam guide which confines the electrons in a beam and guides the beam along the length of the channel. The beam guide also includes means for selectively deflecting the electron beam out of the guide at selective points along the guide so that beam will impinge upon a phosphor screen along the inner surface of the front wall. In each of the channels is a scanning deflector which deflects the path of the beam as it passes from the guide to the phosphor screen so that each of the beams will scan a portion of the phosphor screen.

Abstract: The beam index concept for color television display tubes has been known for some time, and although this color display approach is fundamentally more attractive than the commercially favored three-gun shadow mask tube, techniques for producing the indexing signal have been inadequate. According to the invention, index signals in a single-gun tube with horizontal phosphor stripes, operating in a line (color)-sequential mode, are generated by UV phosphor bars spaced uniformly along each color stripe but with different spacings for each color. As the beam scans a stripe, an optical signal is generated with a frequency corresponding to the periodicity of the phosphor index bars. The optical signal is detected with a UV detector. The amplitude of each frequency will indicate the beam size and vertical position. The index signals are fed to a signal processor which, by simple filtering, will generate error correction signals which are in turn fed to the deflection circuit to correct the beam position. The use of the optical index signal ensures isolation of the beam index signal from the video.

Abstract translation: 彩色电视显示管的光束指标概念已经知道了一段时间，尽管这种彩色显示方法在基本上比商业上有利的三枪荫罩管更有吸引力，但是用于产生分度信号的技术已经不足够了。 根据本发明，在具有水平荧光条纹的单枪管中的索引信号以线（彩色）后序模式工作，由沿着每个颜色条带均匀间隔但每个颜色具有不同间隔的UV荧光棒产生。 当光束扫描条纹时，产生具有对应于荧光体指数条的周期性的频率的光信号。 用紫外检测器检测光信号。 每个频率的幅度将指示光束尺寸和垂直位置。 索引信号被馈送到信号处理器，信号处理器通过简单滤波将产生误差校正信号，该信号又被馈送到偏转电路以校正光束位置。 使用光学索引信号确保光束索引信号与视频的隔离。
