Description of the invention (1) This invention is based on the scope of the patent application. In the so-called co-linear color picture tube, three electrons for red, green, and blue are arranged in a row. Then, the neck and the adjacent tube cone for horizontal and vertical deflection, so that the deflection coil is held as small as possible. Therefore, the deflection sensitivity is limited, because the deflection coil cannot be placed as much as the outer circumference of the tube allows. The purpose of the present invention is to increase this degree. This subject can be solved according to the present invention. The shape of the neck cross-section is roughly matched with the (image) circle. The cross-sectional shape is preferably rectangular. Therefore, the ratio of the major axis of the ellipse to the minor axis of the ellipse is the same in degrees. The way the electron gun is placed away from the neck can be shortened. This is especially applicable to the deflection coil of the side, and the position where the horizontal deflection occurs is close to the electron beam, thus increasing the deflection current value necessary for the deflection. In particular, it can take advantage of the power consumption of both sides of the coil. The invention features a new image tube. Increasing the line output force in the horizontal direction to a higher line frequency of about 30 KHz. The shape of the tube neck of the present invention extends the deflection field to a color image of the preceding preamble, and the same plane in the tube neck is flat against each other. The neck of the tube has a circular cross section. The shape of the coil is matched with the distance of the tube toward the electron beam, which is large. The deflection sensitivity is particularly close to the electron beam, exceeding the deflection sensitivity of the color picture tube, which means that the aspect ratio of the gimmick in the deflection coil area deviates from the rounded corner or forms an ellipse, roughly the distance between the image gimmick width and the height The reduction of the vertical magnetic sensitivity is not suitable for the sensitivity of the transformer, therefore, according to the field in the tube neck. As a result of the bias, the biased aspect ratio is particularly good. When the bias is increased, the upper and lower coils of the present invention can reduce the path and bias to 16: 9, because the pole height should be read from the sensitivity first ifi.

Calculations have shown that the deflection sensitivity can be increased by at least 30% through the change in the neck section of the present invention. Further advantages are as follows: Picture tubes, especially those with higher deflection amplitudes and larger deflection angles, have a crisis called f-shading. This means that the electron beam hits the glass edge of the tube from the electron gun to the image, especially the transition area between the cylindrical neck and the tube cone. The electron beam no longer reaches the image, so it is not helpful for the reproduction of the image. If the electron beam hits the glass wall of the image tube for a long period of time, for example, a few minutes, improper heating of the glass wall and damage to the image tube will actually occur. The risk of such shadows can be reduced by the new shape of the neck. Based on the fact that the cross-sectional shape of the neck is better matched to the shape of the crotch and the right angle during the beam deflection. A specific example of the present invention can be illustrated by the following figures. In the drawings: FIG. 1 shows the construction principle of the same-line color image tube; FIG. 2 is a cross-sectional view of the neck of a known color image tube; FIG. 3 is the color of the invention Cross-sectional view of the neck of the image tube; Figure 4 is a cross-sectional view of different necks of the color image tube of the present invention. Fig. 1 shows a color picture tube 1, a clam 2, a phosphor clam 3, a shadow 4, a cone portion 5, a neck 6, and a cap 7 made of transparent glass, and having a terminal tip 8 to conduct voltage and current. The three electron guns R, G, and B that generate the electron beams 9, 10, and II are juxtaposed with each other at the level of the neck 6. The electron beams 9, 10, and 11 converge on the phosphor 3, hitting the designated color band or color point to produce a color image. Figure 2 shows the cross section of the neck 6 of a known color picture tube. The cross-section is round%. Read the ifi back \ ΓΓ; Note Λ t. The paper on this page is printed on the paper. The standard is used in the Ming Dynasty Qu Jiaju standard (CNS) T4 rule (210X297 g; ¢) Ministry of Economic Affairs The quasi-administrative Beigong Group cooperated with Du to produce the fifth, invention description (3) shape, and the deflection coil 12 was fitted on the outer periphery of the neck 6. It can be seen that the distance between the deflection coil 12 where the vertical magnetic flux line 13 for horizontal deflection occurs and the electron guns R, G, and B is determined by the outer periphery of the neck 6 and cannot be reduced. However, this distance impairs the deflection sensitivity, because the deflection sensitivity decreases as the distance of the deflection line from the electron beam increases. In Fig. 3, the cross-sectional design of the neck 6 is different from the circle in Fig. 2. The cross section is somewhat rectangular with rounded corners. This cross-sectional shape roughly corresponds to the shape of the image tube of the picture tube 1 with an aspect ratio of 16: 9. This means that the ratio of the length of the neck 6 rectangle to the width is approximately the same as the ratio of the width of the neck to the height. For a color imaging machine with an aspect ratio of 16: 9, the rectangle represented by the neck 6 also roughly has this aspect ratio. It can be seen that the distance of the deflection coil 12 from the electron guns R, G, and B, that is, from the electron beams 9, 10, and 11 (determining the deflection sensitivity) is significantly shorter than that in FIG. 2. In Figure 4, the neck 6 has an oval cross-section. Here, the ratio of the long axis of the ellipse to the short axis of the ellipse is approximately equal to the ratio of the width to the height of the image tube for the picture tube 1. The deflection coil part is located in the region of the tube neck 6 and the extension end is in the region of the tube cone section 5. The shape of the deflection coil matches the shape of the neck of Figure 3 or 4 'to achieve the smallest possible geometric distance between the deflection coil and the electron guns R, G, B and the generated electron beams 9, 10, and 11.
