Abstract

A color cathode ray tube equipped with an in-line electron gun for emitting three adjacent electron beams of an in-line arrangement toward a fluorescent screen, and a main lens for focusing said three adjacent electron beams on the fluorescent screen. The main lens comprises two cylindrical electrodes arranged in a spaced relationship in the direction of tube axis, each having an opening with an approximately elliptical cross section and having therein a plate electrode (with a beam passing area). The two cylindrical electrodes are given different voltages, wherein the following inequalities are satisfied: 5.0 > S (S being a beam space between central axes of said three adjacent electron beams), D > S and 55S - 20D >= 145.5 (D being the diameter of an opening aperture in the direction perpendicular to the three electron beams arranged in line and on the relative terminal of two cylindrical electrodes).

Description of the invention (1) Background of the present invention 1. The scope of the present invention The present invention relates to a color cathode-ray tube configured with an in-line electron gun so configured so that Three electron beams are emitted towards the screen in a horizontal line * 2. An earlier technique is described in a cathode ray tube equipped with at least one electron gun containing a cathode and a plurality of grids, a deflection device and a screen I am familiar with the following techniques to obtain a better image that extends from the central part to the screen circle: a technique is used to provide an electrode of an astigmatic lens forming a focusing lens (main lens) In the area, and the other is to form an electron beam passing hole of an electrode of an in-line electron gun constituting the main lens into a slot, and the size of the central and each side electron beam passing holes is different (Japanese Patent Laid-open No. 64368/1976) · This type of color cathode ray tube is shown in Figure 1, equipped with at least one vacuum container including a panel 61, a leak 62 and a neck 6 3 (they are made of an insulator such as glass), an electron gun 6 4, a shadow mask 65, and a fluorescent screen 6 6 contained in a vacuum container. The electron beam emitted on the screen 66 reproduces an image. Figure 2 is a cross-sectional view of the main part of the main lens schematically illustrates the structure of the conventional in-line electron gun used in the above cathode-ray tube.

Align these central axes 021, 022, and 023 with the cathodes 08 corresponding to the first, second, and third grids 〇11 | 〇12 and 013. Each of the openings of 09 and 010 and the inner cylinders 0 1 5, 0 1 6 and 0 1 7 connected to the openings of the third grid 013 are aligned with each other, and they are arranged On the almost parallel same plane *, the central axis of the central opening portion of the fourth grid 014 and the cylinder 0 1 9 connected to the central opening portion are aligned with the central axis 0 2 2. However, the central axes of the opening portions on both sides and the internal cymbal pillars 0 1 8 and 0 2 0 connected to each opening portion are not aligned with their corresponding central axes of the third grid, but rather They are shifted slightly outwards. The symbol S in Fig. 2 represents the central axis of the electron beam 0 2 1, the interior between 0 2 2 and 0 2 3 * L represents the central axis of the external electron beam 0 2 1 and 0 2 3 The distance from the inner wall of the neck and D represents the internal diameter of the inner cylinder connected to the opening portion of the G 3M pole 0 1 3 * The in-line electron gun with the above structure operates as shown below.

Description of the invention (3) The electrons from thermionic ions emitted by three cathodes 0 8 '09 and 0 1 0 heated by a heater are passed through a positive voltage applied to the second grid 0 1 2 A three-electron beam is drawn toward the first grid 0 1 1 and then these three electron beams are passed through the first grid 0 1 1 Make holes, and then pass through the openings of the second grid ο 1 2 • Each of the m is accelerated by the positive pressure applied to the third grid 013 and the fourth grid 014 and enters the main lens. In this case A low voltage of about 5 to 10 KV is applied to the third grid 013 constituting the main lens: a large voltage of 20 to 3 5 KV applied to the screen is applied to the funnel 6 through a cover. A conductive film on the inner wall of 2 is applied to the fourth grid 0 1 4 * This | An electrostatic field is applied to the third grid 013 with a low voltage applied thereto and a fourth grid is applied with an electric energy to it The voltage difference between the poles 014 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 bent through an electrostatic field. As a result, three branches The electron beam is focused on the screen. Also, because the central axes of the relative openings of the cylinders of the sub-beams of the third grid 0 1 3 and the fourth grid 0 1 4 are not aligned with each other. The main lens is not symmetrical about the central axis. Therefore, the secondary electron beams are deflected inward so that they converge on the screen according to the central electron beams. • By converging the three electron beams on the screen, the R, G, and B three-color images generated by the three electron beams are correctly aligned to display a color image.

Description of Invention (4) In the in-line electron gun constituted as described above, the three electron beams cannot meet the convergence situation because the accuracy and composition accuracy of the electron gun components are slightly changed. Because the convergence of the electron beam must be adjusted. In this convergence adjustment When the beam distance s between the electron beams is reduced, the deviation of the convergence conditions of the electron beams is reduced and adjustment becomes easier. • From the results of past experiments, we know that the value of S should be set to less than about 5mm. However, in the traditional In the structure of the focusing electrode, the opening diameter of the focusing electrode is limited to a value that is smaller than the beam distance S between the adjacent sharp beams entering the sharp edge. Therefore, the restriction is added to the opening diameter for setting. The velocity S between sub-beams is less than 5. The effective aperture of the focusing lens of each electron beam is determined by this aperture diameter.

And * In the case of such a large increase in the neck diameter, it is possible to reduce 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 in-line electron gun When the diameter of the main lens increases, 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 electron beam diameter in the main lens is excessively increased, the beam spot diameter on the screen will increase due to this increase in lens aberration. That is, the electron beam diameter in the main lens has an optimum value. Therefore, as described above, the straight line, 3, or the above formula (3) in FIG. 6 is obtained. 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 (with the in-line electron gun). The arrangement direction of the lens is orthogonal to the diameter D). In the case of an electrode with three patterned openings, the lens aperture D (mm) is equivalent to the diameter D of each circular opening. When the relationship between the electron beam spacing S and the lens diameter is in a region under 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 3.9mm, the beam spot diameter increases too much and this phenomenon may cause problems. • Therefore, the lens diameter must be 39mm or more. In addition, the size 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 Η is in the practical range ------- --- ¢ ---- „--- ^ ------ ^ (Please read the notes on the back before filling in: this page) Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the paper scale is used in China National Standard (CNS) A4 Specification (2) 0 X 297 mm) -19-Printed at 41: 371 A7 ________B7____ by the Central Bureau of Standards of the Ministry of Economy No electron beam strikes the electrode, and the diameter of the beam spot can be minimized.
