Each electron beam is accelerated by a positive voltage applied to the third grid 013 and the fourth grid 014 and enters the main In this case, a low voltage of approximately 5 to 10 KV is applied to the third grid 013 constituting the main lens; a pseudo voltage of approximately 20 to 3 5 KV applied to the screen is passed through the cover A conductive film covering the inner wall of the bucket 6 2 is applied to the fourth grid 0 14 • This * — a static field is applied to the third grid 013 by applying a low voltage to it and a high electric house to A voltage difference between the fourth grid 014 thereon is formed between the third grid 0 1 3 and the fourth grid 0 1 4 Therefore, the path of the three electron beams in the main lens is curved by the electrostatic field. As a result, the three electron beams are focused on the screen. Moreover, because the third grid 0 1 3 and the fourth grid The central axes of the opposite openings of the cylinders of the sub beam of 0 1 4 are not aligned with each other, so the main lens of the sub beam is not symmetrical about the central axis. Therefore, the sub electron beam is deflected inward to follow the central electron. The beam converges on the screen • By this, the three electron beams are converged on the screen so that the three-color images of R, G, and B generated by the three electron beams are correctly aligned to display a color image.

Description of the invention (4) In the in-line electron gun constituted as above * due to slightly changing the accuracy of the components of the electron gun and the accuracy of the combination * the three electron beams cannot meet the convergence situation • because the convergence of the electron beam must be made Adjustment · here Convergence adjustment * When the beam distance s between the electron beams is reduced, the deviation of the convergence condition of the electron beam distance is reduced and adjustment becomes easy. • From the results of past experiments, we know that the S value should be set to less than about 5mm. • In the conventional focusing electrode structure, the opening diameter of the focusing electrode is limited to a value smaller than the beam spacing S between the adjacent electron beams entering the lens. Therefore, a restriction is added to the opening diameter to set the electron beam interval. The rate of fire interval S is less than 5 from m. The effective aperture of the focusing lens for each electron beam is determined by this aperture diameter. Therefore, a problem occurs that the spherical aberration of the lens increases and the electrons decrease as the aperture diameter decreases. Increasing beam spot diameter. To solve the above problem * A structure is known (it is shown in Japanese Patent Laid-Open Patent No. 103752/1983). This structure can reduce spherical aberration while maintaining the beam spacing S at less than 5 mm. The structure of the electron gun disclosed in the above bulletin will be schematically described with reference to FIG. 3 as follows: * 圚 3 (a) is a longitudinal section BI of a basic part, illustrating the main lens of the in-line electron gun and FIG. 3 (b) is a cross-sectional view of the essential part of FIG. 3 (a) taken along the line A--A 'of FIG. 3 (a) *' In FIG. 3, the reference numeral 1 3 is the third columnar grid The extremely open cross section is almost elliptical, and 14 is the fourth cylindrical grid.

In this case, if the diameter D in the vertical direction is greater than the beam spacing S adjacent to the electron beam, a problem is caused by the electron beam striking the 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 In order to achieve the above purpose, 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 the screen and the main lens so that the three electrons The beam is focused on a fluorescent screen, configured with a planar electrode having an electron beam passing region in two cylindrical electrodes (these electrodes are self-generating electron beams I ---; ------ install-- --------- ^ (Please read the notes on the reverse side and fill in the dream page) The paper size applies to the Chinese standard (CMS > Α4 size (210X297mm) & A7 B7) Description of the invention (6) The direction of the electron beam emitted by the device (6) is configured at an interval) and has an approximately elliptical opening cross-section that is maintained at different potentials, which is particularly when the / three adjacent electric When the distance between the centers of the beams is indicated by s (mm), when the opening diameters of the two cylindrical electrodes perpendicular to the arrangement direction of the electron beams in the line are indicated by D (mm), the above S and D meet the following relationship: S < 5.0, D > S, and 55 S-2 0 D will be 145.5.

The above structure can prevent problems occurring when the three electron guns converge. The structure shown in the figure is used as the main lens, so the diameter D of the opening of the cylindrical electrode (its opening cross-section is approximately oval) in the direction of the three electron beams perpendicular to the column is almost equal to the diameter of the main hole formed by the electrode The diameter of the lens can reduce the spherical aberration by making the main lens larger than the conventional one, and reduce the electron beam by making the vertical diameter D larger than the electron beam spacing S between the centers of adjacent electron beams compared with the conventional one.

Case of a color cathode ray tube (where the diagonal of the fluorescent screen is 5 1 cm and the deflection angle is 9 Οβ) f When the fourth grid electric grinder is 2 5KV, the third grid voltage is 7KV and the electron beam current When the value is 4 m A, these values are obtained by analysis. From this circle, it was found that the optimum electron beam diameter increases when the lens diameter increases. However, in an electron gun having the main lens structure shown in circle 3, If the diameter D of each opening in the direction perpendicular to the three electron guns in the queue is greater than the electron beam spacing S, the diameter of the electron beam supplied to the main lens must also be increased in accordance with the increase of the diameter D to be used as a beam.

The diameter corresponds to the vertical diameter D of the opening of the cylindrical grid. Therefore, the relationship between the electron beam spacing S and the vertical diameter D of the opening of the cylindrical grid is obtained.

In addition, when the diameter of the neck is increased to such an extent • By changing the composition of the deflection yoke, it is possible to suppress the reduction of the deflection sensitivity as low as 10%, 15%, or 20%, respectively. In order to effectively use the main gun of the in-line electron gun Lens aperture. When the diameter of the main lens increases, the diameter of the electron beam supplied to the main lens must be increased to prevent the spot on the screen from expanding due to the space charge effect. However, if the electron beam diameter in the main lens is increased, Excessive increase | Due to this increase in lens aberration, the spot diameter of the spot on the screen increases. That is, the diameter of the electron beam in the main lens has an optimal value. Therefore, as above, a straight line in 圚 6 is obtained. la # or the above formula (3) * In the case of a cylindrical electrode, the lens diameter D (mm) corresponds to the diameter D of the vertical direction of the opening of the cylindrical electrode (a direction orthogonal to the arrangement direction of the electron guns in the line). . In the case of an electrode having three circular openings, the lens aperture D (mm) corresponds to the diameter D of each circular opening. When the relationship between the electron beam distance S and the lens diameter is in a region below a straight line, when the beam is placed with a large current, no electron beam flashes on the electrode. However * if the lens diameter is less than 3.9mm, the beam spot diameter increases too much and this phenomenon may cause problems *. Therefore, the lens diameter must be 3.9mm or more. Moreover, the dimension S must be 4.1 mm or more. After meeting all the above conditions, after 24 hours of operation, the electron beam movement distance P may be within a practical range and the deflection sensitivity is within the practical range of this paper.
