摘要： A cathode ray tube has at least one electron gun (6, 11, 12, 14) with a cathode (6), a control grid (11) and a focusing unit (14), as well as a strip (9) of electroconductive material connected to the ground potential and applied on the cathode ray tube in a substantially parallel direction to the outer lining (8) of the tube. Means and measures are disclosed which largely eliminate the harmful effects of high-voltage flashovers. The invention is applied in monitors.

摘要： Electron-optical device having an electron-emitting region, a longitudinal axis and an arrangement of apertured electron grids along the axis. The first grid has an aperture for passing electrons, which aperture is located further outwards with respect to the longitudinal axis than the emitting region. One of the further grids is provided with a shield so as to shield the edge wall of the aperture, if it is located within direct view of the electron-emitting region, from incidence of positive ions.

摘要： The present invention comprises cyclotron display devices similar to cathode ray tubes (CRTs) in which the CRT electron gun is replaced by one or more cyclotrons that produce electrons using lower voltages and energy costs than a CRT electron gun does. This can be done both with monochrome and color displays, as disclosed. In addition, the electrons emerge from the cyclotron with adequate velocity, thus obviating the need for accelerating electrodes. The need for electron focusing is also greatly reduced, or eliminated, since the electrons emerge from the cyclotrons as beams, rather than as diffuse clouds. The cyclotron display assembly can be made to be significantly shorter than the conventional electron gun CRT. In addition, an array of cyclotrons, rather than just a single one, can be used, so that each cyclotron maps to a fractional portion of the video screen. This further shortens the length of the cyclotron display.
摘要翻译：本发明包括类似于阴极射线管（CRT）的回旋加速器显示装置，其中CRT电子枪被一个或多个回旋加速器代替，该回旋加速器使用比CRT电子枪更低的电压和能量成本产生电子。如所公开的，这可以通过单色和彩色显示器来完成。另外，电子以适当的速度从回旋加速器出射，因此不需要加速电极。对电子聚焦的需求也大大减少或消除，因为电子从回旋加速器射出而不是散射云。回旋加速器显示组件可以做得比传统电子枪CRT短得多。另外，可以使用一系列回旋加速器而不是单一回旋加速器，以便每个回旋加速器映射到视频屏幕的小数部分。这进一步缩短了回旋加速器显示器的长度。

摘要： A multi-beam electron gun for use in a monochrome cathode ray tube (CRT) such as used in a black and white television receiver, a projection television receiver, or a computer monitor includes (G1) control (46) and (G2) screen grids (48) each having a plurality of vertically aligned apertures for forming electron beams which are deflected in unison across the CRT's display screen to simultaneously trace a plurality of vertically spaced, horizontal scan lines with each display screen sweep. The electron beams are deflected across the screen in a raster-like manner with each beam containing video information for each adjacent scan line. The (G1) control grid includes a plurality of discrete conductive portions each including a respective beam passing aperture and each coupled to a respective video signal source, with the video signal sources including memory for storing video signal information for subsequent display.

摘要： A color cathode ray tube (CRT) includes a multi-beam electron gun (10) capable of operating in two or more modes for use as either a television receiver display or as a high resolution video monitor. The electron gun (10) directs a plurality of electron beams (60b, 60g, 60r; 62b, 62g, 62r) onto the CRT's display screen with the electron beams arranged in two or more groups. In one group of electron beams (62b, 62g, 62r), the beam forming portion of the electron gun, i.e., its G1 screen (22) and G2 control grids (24), provides small diameter electron beams having reduced spot size on the CRT's display screen for high video image resolution when used as a monitor for graphics and/or character display. In another group of electron beams (60b, 60g, 60r), the beam forming portion of the electron gun (10) provides electron beams having a larger diameter and current for increased video image brightness when used as a television receiver.
