Description of the invention (1) The invention relates to an axial electron gun for producing three electron beams and a unit for deflecting the electron beam across a color selection electrode . Such a display device is known. The current behavior is to make the outer surface of the color display window a flatter surface, so that the image displayed by the display device feels like a flat surface to the viewer. In any case, adding up the radian diameter of the outer surface causes a lot of problems. The arc surface diameter of the display window and the color selection electrode must be enlarged and when the color selection electrode becomes flatter, the mechanical degree of the color selection electrode is reduced and the sensitivity is uneven and the vibration is increased. This problem is replaced by t. The arc of the inner surface of the display window is larger than the arc of the outer surface, but the actual situation is that a color selection electrode has a relatively small arc that can be used. As a result, the unevenness and the vibration direction can be reduced, but other problems are generated instead. The display window has a larger thickness on the side than on the center portion. As a result, the weight of the display window increases and the density of the image near the edge portion becomes completely lower. EP 0,421,523 discloses a color cathode ray tube with an axial gun, a pin-cushion correction yoke, and an eyebrow-responsive electronic-optical distortion correction device. The correction device includes two pairs of coils, each pair having a coil on each external electron beam on the plane of the beam. The coil pair is spaced apart between the gun and the yoke along the P axis and is driven by a sawtooth wave current with a rectangular connection and envelope synchronization that is equipped with a scanning screen scan to correct. The asymmetrical eyebrow light effect is on the scanning screen. This is obviously a good defect.

Description of the invention (3) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, 极 Ray 营 # h +, Hundred-display window 2, a conical part 3 and a neck 4. The neck 4 is equipped with an axis for generating the second life names c Ί ^, Wang Yi electron beams 6, 7, and 8 to extend into a plane, and an axis extending in the X direction of the rectangular X-Z cooperative system " 弋% sub gun 5. -In the third aspect, the direction extends perpendicular to the plane of a line (not shown in the figure). Conventionally, in the operating situation, the position of the tube at the X-Z plane is consistent with the horizontal plane and its Z-direction is consistent with the vertical direction. The surface of the display is equipped with a display screen 10, which contains a large number of phosphorous elements that emit light into red, green, and blue. On the way to the display screen, the electron beam borrows an electromagnetic deflection unit. 51 and a color selection electrode 11 arranged in front of the display screen 2 and a thin plate including an opening 12 are deflected across the display screen. The three electron beams 6, 7, and 8 pass through the openings 12 of the color selection electrode at a very small angle, and each hail beam strikes only one color phosphorous element. In addition, entering the coil holder 13, the deflection unit 51 is included in a vertical direction to deflect the deflection coil i 3 'of the electron gun. A ring-shaped element 2 i, a so-called yoke, is fixed near the deflection yoke 1 3 ′.軏 The purpose of the iron ring is usually to make the iron coils' magnetic field lines into a "closed circuit". If there is no yoke ring, the excessive current flowing through the deflection coil will be used to dry a normal magnetic field (magnetic force). The display device further includes a device for generating a voltage when it is fed to the electric gun in the meridian route. The deflection plane 20 is a systematic indication of the distance p between the electron beams 6 and 8 and the distance q between the color selection electrode and the display. The distance q is inversely proportional to the distance p. The color display device includes two electron beam convergence influencing units 1 4 and 1 4. The interfering ring disturbances of the display are as shown on the screen. ------------------------ ---- (Please read the precautions on the back before filling out this page) 6-480524 Printed by A7, Consumer Cooperatives, Intellectual Property Bureau, Ministry of Economic Affairs, 5. A description of the invention (4 In operation, use a first unit 1 4 The h U ^ 4 operation is to turn the outermost electron beams to each other as a function of deflection in one direction, and the first one is 14 to dynamically turn the outermost electron beams to the phase and the ancient A η ^ ^ 1 It's called the Tuzhou Junwan. And the unit 14 makes the electron beam turn in the opposite direction. As a result, the electron beam deflected by Lei Zi 卞 g from the distance between the children's end and the electron beam which is not deflected is smaller. The distance p is small, and the distance q may be increased to cause the loneliness of the color selection electrode _ additional unrestricted design. When the sensitivity is uneven and the vibration is reduced, using the unrestricted design can increase the arc of the color selection Positive influence on the strength of the color selection electrode.. The positions of the two units 14, 14 'are at a distance from each other, the first unit The position of Yuan Yuan is close to the electron gun, which can be called “gun quadrupole”, and the position of the second unit ^ 4, which is near or at the deflection unit, can be called “iron quadrupole”. Unit 1 4 ′ and Deflection unit 5! It is more convenient to put four wires on the ring-shaped element 2 ι to form a full moon bean. 'This coil generates a dynamic electromagnetic quadrupole magnetic field. In operation, units 14, 14' affect the deflection of the electron beam and cause No artificial artifacts displayed on window 2. Conventional cathode ray tubes (CRTs) have a non-linear phenomenon in the vertical range [that is, a non-linear function of the electron beam movement / flow through the deflection coil current] 'The deflection of the electron beam on the outermost side of the display window requires a relatively small current. A non-linear method of electronic correction, the so-called vertical s-correction can occur in the television set and used in the tube. The action makes the deflection of the electron beam a more linear step. This kind of collision that corrects the non-linear deflection phenomenon of S-correction is an unnecessary one.

This device looks like a horizontal I-rectangular scanning screen and a vertical line displayed on the screen as the same two-pin, pin-cushion shape. On the side of the ir f turning inward, on the edge, the obvious application of the unit worker 4 will increase this artificial artifact. The purpose of the invention is to reduce the impact on the above-mentioned unit 14, artificial artifact. It is based on μ knows that the unit 丨 4 is the ring-shaped element 21 I that is the main influencer facing the display window 2. Therefore, the ring-shaped unit 2 is divided into two = (axially separated) parts, and a four-pole coil is wound on one of the two parts. It is better to have the iron core of the t-pole coil wound close to the electron gun. This countermeasure provides an opportunity to move the two core parts independently of each other, so that the scanning screen and convergence performance of the tube are improved. Figs. 2A and 2B show a specific embodiment of the invention, and Fig. 2A shows a ring-shaped element 2 1 ′, a first point 60, and this part is closest to the electron gun 5. The knife 60 is equipped with four coils 22, which are used to generate a four-pole magnetic field. The line drawing shows the way the wire has been wound into a loop on the mounted-shape element. In any case, the I-coil made in this way is the main invention. The four-pole coil can also be wound into a saddle-like shape. In order to facilitate the winding process and to maintain the coil 22, the 7L pieces of the respective wires are correctly positioned on the first part 60, and the first part is provided at its end with a ring 6 having a coil winding groove positioned therein 4, 6, 66 . FIG. 2B shows a second portion 68 of one of the ring-shapes 21 ', which portion is closest to the display window 2. As shown in FIG. When the two parts are mounted to the pipe, the two parts can be interconnected with 60, 68 by conventional connection means such as adhesive, tape, or the like. The connection of the two parts does not need to take particularly appropriate work. -8- This paper size is in accordance with China National Standard (CNS) A4 specification (210 X 297) (Please read the precautions on the back before filling this page) > Loading ---- ― 一 a an —II Ύ 一口Printed by the Employee Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 480524 A7
