V. Invention Description (4) In the in-line electron guns constituted as described above, the three electron beams cannot meet the convergence situation because the accuracy of the electron gun components and the combination accuracy are slightly changed. • Because it is necessary to adjust the convergence of m sub-beams • In this convergence adjustment • When the beam distance S between the electron beams is reduced, the deviation of the electron beam distance convergence conditions is reduced and adjustment becomes easier. "Experimental results" learned that it is advisable to set the value of S to less than about 5mm. However, in the structure of a futuristic focusing electrode, the aperture diameter of the focusing electrode is limited to be smaller than the beam spacing S between adjacent electron beams entering the lens. The numerical value • Therefore, the restriction is added to the diameter of the opening to set the beam velocity distance S between the electron beams to be less than 5 # m. The effective aperture of the focusing lens of each electron beam is determined by this opening diameter *. One problem is that the spherical aberration of the lens increases and the diameter of the electron beam spot increases when the opening diameter decreases. In order to solve the above-mentioned problem, a structure is known (it was disclosed in Japanese Patent The structure disclosed in Patent Publication No. 103752/1983 can reduce the spherical aberration while maintaining the beam distance S to be less than 5mm. The structure of the electron gun shown in the above announcement will be schematically described with reference to FIG. 3 as follows. Circle 3 (a) is basic Partial longitudinal cross-section view, exemplifying the main lens of the in-line electron gun, and Fig. 3 (b) is a transverse section of the essential part of Fig. 3 (a) taken along line A-A "of circle 3 (a) Figure * 〃 In Figure 3, reference numeral 1 3 is the third cylindrical grid whose opening cross section is almost oval, 14 is the fourth 圚 cylindrical grid whose opening cross section is also almost oval, 13-1 is Via one of the planar electrodes provided in the third grid 1, 1 4- 1 is via a plane H provided in the fourth grid 2.--»-n 1 ^ 1 -H · I ^ —1-- ^^ 1 1 ^ 1 ϋ 3-- (Please read the notes on the back before filling in this page) This paper size is applicable to China National Standard (CIS'S) A4 size (210x 297 mm) Patent Application No. 87103483 A7 Β7 Revised 2 / μ in March of the Republic of China, printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs ^ ### 1: 费 莫 ^ 走 ¥ 准 | ^ 57 5 Description of the invention f) Electrodes, 1 3R, 1 3G and 1 3B are holes (openings) through the electrons of the plane electrodes 1 3-1 and 14R, 14G and 14B are holes (openings) through the electrons of the plane electrode 14-1 ) And 21, 22, and 23 are the central axes. As shown in FIG. 3 (b), the in-line directions of the openings 1 3R, 1 3G, and 1 3B of the plane electrode 1 3-1 perpendicular to the third electrode 1 The diameter D in the (horizontal direction) direction (vertical direction) is approximately equal to the diameter of the main lens formed via the electrode. As the diameter D increases, the spherical deviation decreases and the electron beam spot diameter also decreases. However, even in the above configuration, another problem occurs as follows: That is, in order to increase the diameter D in the vertical direction and decrease the diameter of the electron beam spot on the screen, the electron beam diameter in the main lens electrode must be increased. In some cases, if the diameter D in the vertical direction is larger than the beam spacing S adjacent to the electron beam, a problem is caused that the electron beam flashes on a planar electrode in the grid, especially when the beam has a large current. An object of the present invention is to provide a cathode ray tube equipped with an in-line electron gun which does not cause a problem in condensing three electron beams and allows the main lens diameter to be increased in such a manner that the electron beam does not strike the third grid. Of the plane electrode. In order to achieve the above object, the present invention provides a color cathode ray tube equipped with an in-line electron gun including at least an electron beam generating device for emitting three electron beams installed in the line toward a screen and a main lens so that the three electron beams are focused on the fluorescent screen. On the light curtain, a flat electrode with an area through which the electron beam passes is arranged in two cylindrical electrodes (these electrodes are self-generating electron beams.

Further, the characteristic of the color cathode ray tube is: two cylindrical electrodes constituting the main lens are provided. Each of the openings facing each other includes a single opening suitable for three electron beams. In addition, a color cathode-ray tube configured with an in-wire electron gun configured as described above may involve a problem that if the distance between the electron beam and the inner wall of the neck that shields the in-wire electron gun is too small, the The high voltage on the funnel part of the cathode ray tube, the inner wall of the neck becomes high potential, and the electron beam is deflected due to the electric field generated by the high potential through the inner wall of the neck slope glass, and when the color cathode is continuously operated When the tube lasts for a long time • The three electron beams will not be focused on the screen. In order to increase the distance between the electron beam and the inner wall of the neck, which is used to shield the electron gun in the line, the diameter of the neck must be increased or the distance between the electron beams adjacent to the electron beam must be reduced.

Description of Invention (7) However, if the diameter of the neck is increased, the distance between the electron beam and the deflection yoke is increased. It also increases and degrades the deflection sensitivity of the deflection yoke. If the electron beam distance S is reduced, a problem arises: the distance between the electron beam and the electrodes of the main lens (separating the electron beams in the main lens from each other) is reduced. ) In this case, the diameter of the electron beam is the largest, which causes the electron beam to strike the m-pole of the main lens. If the diameter of the electron beam in the main lens electrode is reduced to avoid flashing, a problem is caused: because the lens magnification is reduced and the space charge effect is increased, the diameter of the beam spot on the screen increases ** The electron beam spacing s causes another problem, that is, the spherical aberration of the main lens increases and because when the main lens is composed of electrodes (each having three circular openings as shown in FIG. 2), The lens aperture D must be reduced. So the diameter of the electron beam spot on the screen is further increased. Another object of the present invention is to provide a color cathode ray tube equipped with an in-line electron gun. The above-mentioned various problems of the earlier technology are solved. And the focus characteristic is improved by eliminating the influence of the potential of the inner wall of the neck and reducing the static focus deviation under long-term operation. In order to achieve the above-mentioned object, according to the present invention, a color cathode ray tube equipped with an in-line electron gun is provided with an electron beam. Device to emit three electron beams towards the screen and a lens including the two electrons held at different potentials It is separated from each other and configured to focus three electron beams on the screen, which is characterized in that the outer diameter of the neck 63 of the electron gun used to shield the line is indicated by T (mm) and adjacent The size of the paper is applicable to the Chinese National Standard (CNS) A4 (210X297 mm) (please read the precautions on the back before filling this page) -10-419696 A7 B7 V.

Detailed description of the preferred concrete window embodiment The above-mentioned configuration can prevent problems occurring when the three electron guns are converged. Also, since the structure shown in FIG. 3 is used as the main lens, the direction of the three electron beams perpendicular to the column is used. , The diameter D of the opening of the cylindrical electrode (the cross-section of the opening is an approximate ellipsoid) is almost equal to the diameter of the main lens formed through the electrode, which can make the diameter of the main lens larger than that of a Futuristic constructor and reduce spherical aberration. The diameter of the electron beam spot is reduced by making the vertical diameter D larger than the electron beam distance S between the centers of adjacent electron beams compared with the conventional one. 〃 In a line electron gun, in order to effectively use the main lens Diameter.

Description of the invention (14) Ray tube • The large-diameter lens can be obtained by optimizing the diameter of the three electron beams arranged perpendicular to the electrostatic focusing electrode passing through the main electrode of the electron gun in the line. And it can reproduce high definition images. The following is a description of color cathode rays. Among them, the influence of the potential of the inner wall of the neck is eliminated and the deviation of static convergence after long-term operation is reduced. Figure 8 is a graph showing the central axis of the m sub-beam from the three-m sub-beam to The relationship between the distance L (mm) of the inner wall of the neck and the electron beam movement P (mm) on the screen after 24 hours of operation * where the abscissa indicates the minimum distance L (mm) between the central axis of the electron beam and the inner wall of the neck ) And the ordinate indicates the moving distance P (mm) after 24 hours of operation.

In order to prevent such a through-hole 'called a neck glass from penetrating, the thickness h (mm) of the glass neck is required to be 2.5 mm or more. Therefore, by determining the outer diameter T (mm) of the neck glass and the electron beam spacing s (mm), it is possible to keep the electron beam moving distance P within an acceptable range after 24 hours of operation so that they conform to the following formula: 2S 10 14.6 $ Τ Figure 9 is a graph showing the relationship between the outer diameter τ of the neck glass and the deflection sensitivity of the deflection yoke, where the abscissa indicates the outer diameter T of the neck glass and the ordinate indicates the deflection seal of the deflection yoke.

Description of invention M) mm With an outer diameter of 28.1 mm or less, it is possible to set the deflection sensitivity within a practical range. Moreover, in the case of such a large increase in the diameter of the neck, it is possible to suppress the reduction of the deflection sensitivity by as low as 10%, 15%, or 20% by changing the composition of the deflection yoke. In order to effectively use the main lens of the in-line electron gun Aperture, when the diameter of the main lens is increased, the diameter of the electron beam supplied to the main lens must be increased in order to prevent the focused spot on the screen from expanding due to the space charge effect. However, if the diameter of the electron beam in the main lens is excessively increased, the diameter of the beam spot on the screen will increase due to the increase in lens aberration. That is, the electron beam diameter in the main lens has an optimum value. Therefore * as above, obtain the straight line in Figure 6 or the above formula (3) »In the case of a cylindrical electrode, the lens diameter D (mm) is equivalent to the vertical direction of the opening of the cylindrical electrode (arranged with the in-line electron gun) Direction is orthogonal)) diameter D. In the case of an electrode having three circular openings, the lens aperture D (mm) corresponds to the diameter D of each 圔 -shaped opening. When the relationship between the electron beam spacing S and the lens diameter is in a region below a straight line 'a ^, when the beam is a large current flow * no electron beam flashes on the electrode. However, if the lens diameter is less than 3.9 mm, the beam spot diameter increases too much and this phenomenon may cause problems. Therefore, the lens diameter must be 3.9 mm or larger. Moreover, the size S must be 4 -1 mm or more. After complying with all the above conditions, after 24 hours of operation, the electron beam movement distance P may be within the practical range and the sensitivity of the deflection disk is in the practical range.
