Description of the invention (1) Background of the invention: The present invention relates to a cathode ray tube, especially a multi-electron beam marking type cathode with a horizontal phosphor stripe. Multi-beam index cathode ray tube 〇 Previous technology: According to the traditional cathode ray tube, there is a cathode ray tube without a color selection electrode or shadow mask. This kind of cathode The ray tube is generally called an index or beam index cathode ray tube. The display screen of the cathode ray tube is provided with a plurality of narrow fluorescent bands arranged parallel to each other along the horizontal direction ( Phosphor stripe), each fluorescent strip can show fluorescence separately when excited by an electron beam scanning in the horizontal direction, and there is a non-electron beam excitation effect between each of the fluorescent strips (ph〇sph〇r stripe) Black strip (b) [ack inoperative stripe], the envelope body (glass enve 1 ope) of the cathode ray tube does not have a sensor (sens 0r), 俾The detector detects the scanning position of the electron beam in the display screen and generates a corresponding index signal. Since the marker signal is a function of the scanning position of the electron beam in the display screen, the This type of mark type cathode ray tube can adjust the image output signal of the electron beam at a predetermined position inside the display screen according to the mark signals to correctly present the received image at the predetermined position. If in the display screen of the standard cathode-ray tube of this kind, the narrow fluorescent bands extend in a vertical direction and are arranged parallel to each other, the mark

586133 SS_9U〇9320 V. Description of the Invention (2) The cathode ray tube must accurately control the turn on or turn of f of the electron gun on it in order to accurately and accurately At high frequencies, the required electron beam is generated. Taking an electron beam with a horizontal sweep time of 62.4 microseconds as an example, when it is horizontally scanned, it scans a horizontal scan with a 400 color pixel. When scanning a horizontal scan line with one of the 3 * 40 0 monochrome image points, the electron beam dwel 1 time at each image point is about 52 nanoseconds. (Nano second) Therefore, the opening and closing frequency provided to the electronic grab must have a flat frequency response (f response) and a frequency as high as 100 MHz. This requirement is obviously difficult to achieve. In addition, since the opening and closing of the electronic grab cannot be completed instantaneously, the distribution of the electron beams on such narrow fluorescent bands extending in the vertical direction will have a Gaussian distribution, resulting in this type of marked cathode ray Part of the electron beam generated by the tube is projected onto the black band between two adjacent fluorescent bands in the display screen which is not excited by the electron beam, so the display screen of the marked cathode ray tube is reduced. The brightness of the rendered image. In the display screen of another conventional mark type color cathode ray tube, there are many narrow phosphor stripes arranged in parallel with each other in groups of three along the horizontal direction, and each fluorescent strip is in the electron Under the excitation of a beam, it can show red, green or blue color light, respectively. If you want to improve the resolution of the image displayed by this another type of color cathode ray tube, you must reduce the phosphor bands in the display screen (phosphor stripe) width to increase its number, and at the same time the inner edge of the display screen must be increased vertically

586133 _ Case No. 91109320_ Year Month _ Amendment __ V. Description of the invention (3) Multiple sets of marking strips (inde X stripe) set in the direction. 俾 Use these marking strips to determine and feedback the electron beam on the display The projection position on the inside of the screen is used to adjust the projection direction of these electron beams, so that each of the fluorescent bands can be accurately projected onto the corresponding fluorescent bands. However, because it is necessary to reduce the adjacent electron beams on the display screen, The distance between the projection positions in the vertical direction must be achieved by means of a very complicated main lens arrangement, so that the electron beams can be converged and converged on the corresponding fluorescent bands. In this case, although using the single electron beam can effectively solve the aforementioned disadvantages caused by multiple groups of electron beams, when using a single electron beam, a very high current is required, and the scanning frequency must be three times that of using more A cathode ray tube with a group of electron beams can accurately project a single electron beam onto the corresponding three fluorescent bands in a unit time. Summary of the Invention: In view of the problems mentioned above when improving the resolution of a conventional marked cathode ray tube image, the inventor has developed the present invention based on years of practical experience and research. The present invention is a multi-electron with a horizontal fluorescent band: a ray tube, one of its electron guns on the end wall of the control grid: all: are oval-shaped openings of the same size, each of the openings The center of the long-called control grid is medium and uniform: plus 4 resembles 1% of the size of the long axis of the Jinggu 忒 opening, to enhance the electric projection point generated by the electronic grab, 丨-^ g is not anal Do not occupy the size of ten or nine f, and hunt the short axis of each opening
