摘要： A method of manufacturing an electron gun (10) for use in a colour display tube (1) is described. The electron gun (10) is provided with an additional electrode (44), positioned between the anode electrode (21a) and the centring cup (23). This additional electrode (44) is part of the beaded unit (29) of the electron gun (10), and this enables very accurate positioning of this additional electrode (44) with regard to its distance to the main focusing section (21) as well as its rotation. This makes it possible to use this additional electrode (44) to improve the quality of the main focusing section (21) by considering it as an integral part of the main focusing section (21). For this reason this additional electrode is referred to as Main lens Field Modifier (MFM) (44). It is shown that by varying the vertical dimension of the apertures (52), (53) of the MFM (44) or the spacing between MFM (44) and main focusing section (21), it is possible to increase the effective lens diameter for spherical aberration, while the effective lens diameter for magnification is kept constant. In other words, the spot performance of the electron gun (10) is improved, while the length of the electron gun (10) is kept unaltered. With a view to obtaining the accuracy needed for a main focusing section (21) with a good tolerance behaviour, this new method of manufacturing an electron gun (10) is of great importance.
摘要翻译：描述制造用于彩色显像管（1）的电子枪（10）的方法。电子枪（10）设置有位于阳极电极（21a）和定心杯（23）之间的附加电极（44）。该附加电极（44）是电子枪（10）的串珠单元（29）的一部分，这使得能够相对于其与主聚焦部分（21）的距离非常精确地定位该附加电极（44），作为以及它的旋转。这使得可以通过将该附加电极（44）作为主聚焦部分（21）的整体部分来考虑来改善主聚焦部分（21）的质量。为此，该附加电极被称为主透镜场修正器（MFM）（44）。示出了通过改变MFM（44）的孔（52），（53）或MFM（44）和主聚焦部（21）之间的间隔的垂直尺寸，可以增加有效透镜直径用于球面像差，而用于放大的有效透镜直径保持恒定。换句话说，电子枪（10）的光斑性能提高，而电子枪（10）的长度保持不变。为了获得具有良好的公差性能的主聚焦部分（21）所需的精度，这种制造电子枪（10）的新方法是非常重要的。

摘要： In a cathode ray tube (10), an electron beam is directed towards a faceplate (20) having an electrode (22) biased at screen potential and is magnetically scanned across the faceplate (20) to impinge upon phosphors (23) thereon to produce light depicting an image. A six-pole coil (15) is disposed proximate the deflection yoke (16) and/or on the tube neck (14) to modify the focus of the red, green and blue electron beams to control focus. An electrode (46) between the tube neck (14) and the faceplate (20) is biased at or above screen potential to deflect electrons over a greater total angle than is obtained from the magnetic deflection.

摘要： A 90 percent electron gun aperture astigmatism is used in conjunction with a four-pole electromagnet (52a-52d) to make a CRT electron beam (54) just focus point and minimum beam width occur closer to the same focus voltage. A single grid (34) may have the 90 percent astigmatism, or astigmatisms in two or more grids may combine to produce an effective 90 percent astigmatism. A four-pole electromagnet (52a-52d) is positioned around the focusing grid and current driving the electromagnet is varied with beam position during normal operation.

摘要： The faceplate (18) of a square-planar picture tube (10) is relatively flat, with a curvature along the major axis and lines parallel thereto that is generally greater near the left and right edges than in the center. An LC tuned circuit (60), coupled to the deflection winding (LH), has a resonant period of oscillation approximately half that of the line trace interval. The tuned circuit (60) introduces an oscillatory correction component into the trace current that provides additional S-shaping in that portion of the line scan intermediate the center and the left or right edge.

摘要： A colour display device (19) is disclosed having an improved focus performance. In state-of-the-art colour display tubes, a static voltage is applied to the focusing electrode (23). This means that only one focus voltage is available for the entire range of beam currents. In general, due to the fact that the diameter of the electron beams (7, 8, 9) increases as the beam current increases, the focus voltage is a function of this beam current, which itself is determined by the cathode voltage. In this invention, a colour display device (19) is disclosed in which the voltage on the focusing electrode (23) is changed as a function of the cathode voltages, thereby significantly improving the focus performance.
摘要翻译：公开了一种具有改进的聚焦性能的彩色显示装置（19）。在最先进的彩色显像管中，静电压被施加到聚焦电极（23）。这意味着只有一个聚焦电压可用于整个光束电流范围。通常，由于电子束（7,8,9）的直径随着电流的增加而增加，所以聚焦电压是该束电流的函数，其本身由阴极电压决定。在本发明中，公开了一种彩色显示装置（19），其中聚焦电极（23）上的电压根据阴极电压而变化，从而显着提高了聚焦性能。

摘要： An electron gun has a pluraltiy of grid electrodes for focusing electron beams radiated from cathodes, at least one of said grid electrodes having a cylindrical body containing a plate member. The plate member has a central electron-beam-passing-aperture and two side apertures. At least one of the two side apertures is contoured by a first circular arc and a second circular arc, two first vertical lines respectively extending outward from either ends of the first circular arc, two second vertical lines respectively extending outward from either ends of the second circular arc, and two connecting lines respectively connecting each of outer ends of the first vertical lines to each of outer ends of the second vertical lines. The electron gun improves the degree of freedom in controlling shapes of beam spots focused on a phosphor screen, thereby heightening the resolution of the cathode ray tube.

摘要： A limiting aperture (44) disposed in a relatively low voltage and electrostatic field-free region in the main focusing lens portion of an electron gun (30) in a cathode ray tube (CRT) provides reduced electron beam spot size and improved video image contrast and purity in the CRT's display screen (42). The generally circular limiting aperture is disposed on the axis (A') of the electron gun (30) and within a charged electrode (G4), or grid, within the main focusing lens. The cylindrically shaped, charged grid is elongated along the gun axis (A') and includes generally circular recesses (52, 54) in facing surfaces thereof, which recesses are also disposed on the gun axis (A') and separated by an inner partition (56) defining the limiting aperture (44). The charged grid is maintained at a voltage VG, with VG
