Description of the Invention Field of the Invention The present invention relates to a monitor device, particularly a flat cathode ray tube monitor device, which is used for the small size of flat cathode ray tubes Monitor. Description of related technology In an ordinary white tube (CRT), an electron beam emitted by an electron gun is radiated on a screen, and the depth to the screen is long, so it is not easy to install it in a narrow space as a monitor. Device, there are thin cathode ray tubes, in which the direction of the electron beam emitted from the electron gun is substantially perpendicular to the viewing direction of the camping light curtain. Figures 1A and 1B show the side view and the top view of the flat cathode ray tube, respectively, where the number 1 Is the neck, number 2 is the funnel part, and number 3 is the light-emitting display part. The fluorescent screen 4 is formed on the inner wall of the light-emitting display portion 3, and when the electron beam is radiated on the screen 4, the light-emitting display portion 3 emits light, and the upper surface thereof is a transparent portion 5, which can make the light-emitting points on the fluorescent film 4 transparent. And see. Numeral 6 is a deflection device placed on the neck 1. Similar to the conventional deflection device, the deflection coil 6a and the iron core 6b are formed. The above-mentioned flat cathode ray tube is conventionally arranged so that when horizontal and vertical deflection currents are supplied to the deflection coil 6a, as shown by the solid line, the electron beam emitted from the electron gun swings up and down and shoots on the fluorescent film 4 to form length and width. A rectangular scan image screen with a ratio of about 4: 3. This paper size is in accordance with China National Standards (CNS) A4 specifications (2 丨 0X297 male f) (Please read the note on the back before filling this page) Order printed by the Central Bureau of Specimen Bureau of the Ministry of Economic Affairs and printed by the Cooper ’s Consumer Cooperative V. Description of the invention [) Therefore, the above-mentioned flat cathode ray tube can be placed on a wall or in a box body, and can be viewed from the display surface in 5 directions and an image screen, which is particularly suitable as a monitor for a portable display device. For example, as shown in FIG. 2A, the surveillance CCD camera 11 is arranged to enlarge the entrance door 10 above the building and display the video signal of the visitor 12 with the C CD camera 11 on the flat cathode ray tube thereon, which can be displayed at the door. See 1 2 full portraits of visitors within 10 minutes. In addition, in the conventional flat cathode ray tube structure, the display surface is the same as the aspect ratio of the TV picture 3: 4, and it is not easy to display the 12 full image of the visitor. Therefore, some devices must be swung up and down to monitor the camera. This requires a mechanism to swing the camera up and down, causing the price of monitor equipment to rise. In addition, a wide-angle lens can also be used to display the full image of the visitor, but the visitor 12 is displayed on a display screen with an aspect ratio of 3: 4, as shown in FIG. 2B. This problem is that the film of the visitor 12 is smaller and difficult to identify. Therefore, it can be seen that the monitor equipment becomes larger, but the structure of today's flat cathode ray tubes displays an aspect ratio of 3: 4, even if the screen is simply widened, the electron beam scanning the screen is ejected by the funnel. The problem of image loss at the corners of the screen is caused. SUMMARY OF THE INVENTION The purpose of the present invention is to provide a flat-type cathode ray tube monitor device in which a deflection coil is used to shorten the rear end portion of the flat cathode ray tube toward the funnel portion of the cathode ray tube. Become a display section where the aspect ratio is 1: 1, which easily solves the above problems.

Description of the Invention ^) Then complete the above monitor device to monitor the customer The images taken with the camera are effectively displayed. The rear end of the bias coil is shortened, which can easily prevent the image loss due to the electron beam colliding with the funnel portion of the flat cathode ray tube during horizontal scanning. The display of the flat cathode ray tube is easily set to a 1: 1 aspect ratio. As a monitor device for surveillance cameras, the effective image area can be widened.

Description of the invention &) A7 B7 Therefore, the offset Y to eliminate the loss of the image center is Y = AX (X / Z ). Figure 6 shows the strength of the magnetic field with or without the bias coil shortening. As shown in FIG. 6, it is assumed that the left side is the display surface side and the right side is the neck side. The peak point P 11 of the coil magnetic field is relatively biased (this point corresponds to the center of the coil), and the bias coil is not shortened. If the end of the coil is shortened by L, The magnetic field peak point P 1 2 (center of deflection) of the deflection coil is shifted to the fluorescent surface side by about L /. Therefore, shortening the end of the deflection coil to obtain L / 2 = Y, that is, as shown in FIG. 4, the electron beam is not affected by the cathode. The inner wall of the funnel portion 22 of the ray tube is constrained, so the length of the fluorescent surface display can be extended by this amount in the vertical direction to obtain a 1: 1 aspect ratio.
