Description of the invention (1) [Technical field to which the present invention belongs] The present invention relates to a method for forming a fluorescent surface having a plurality of fluorescent bodies, and particularly to a method for forming a fluorescent surface using a transfer method . [Know-how] Cathode ray tubes (CRT; Cathode RAY Tube) have been widely used in television receivers and various monitoring devices. The cathode-ray tube is an electron gun provided in the tube (inside the cathode-ray tube), which emits an electron beam toward the fluorescent surface, and the scanning surface is formed by scanning the tube surface with its electron beam. The types of cathode tubes are roughly linear and flat. The linear cathode-ray tube system arranges the electron gun with the emission port of the electron beam facing the fluorescent surface, and has a structure that irradiates the electron beam slightly perpendicularly to the center of the fluorescent surface. On the other hand, the flat-type cathode-ray tube system has a structure in which the electron gun and the fluorescent surface are arranged on a substantially same plane, and the electron beam is irradiated from an oblique direction with respect to the fluorescent surface. Compared with the straight cathode tube, the flat cathode tube can be made thinner. It is mostly used in smaller devices such as the monitor part of the main unit of a walkie talkie device and a portable TV (television) monitor. The cathode ray tube system is a color display in the whole picture ', but even Zhuochun who only uses black and white video (monochrome) for image display needs to be developed. In particular, flat cathode-ray tubes of the black-and-white video display method are mostly used in two-way radios. The cathode-ray tube of the black-and-white video display method, for example, forms the entire fluorescent screen with a white light-emitting phosphor, and scans the fluorescent screen with one electron beam, thereby displaying a black-and-white video image. This paper size applies the Chinese National Standard (CNS) A4 specification (210X297mm1 " • Approved clothing-(Please read the notes on the back before ^ copy this one hundred ^) Order printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs & gt -4- 583706 A7 B7 V. Explanation of the invention (2) [Questions to be solved by the present invention] Please read the precautions before you write this, but even the device using the cathode-ray tube using the black and white video display method also requires part to be performed in color Video display. For example, the combination of walkie-talkie devices with various sensor devices such as fire detectors and gas leak detectors can have the function of the entire system as a security system. In the case of such a system configuration, users are reminded to pay attention This means that the parent machine uses a different color (for example, red) from the usual black-and-white video display to indicate that an abnormality has occurred to implement a warning display. Therefore, the applicant in Japanese Patent Application No. 2000-045 1 14 and Japanese Patent Application In 2000-1117594, etc., a technology was proposed in which even a cathode ray tube of a black-and-white video display method can partially perform color display. A brief description of the applicant's previous invention will be given in accordance with Figs. 14 (A) and (B). Figs. 14 (A) and (B) are simplified illustrations of the image display part of the flat cathode wire tube. As shown in FIG. 14 (A), the flat cathode ray tube 110 of the conventional black-and-white video display method is formed by a monochromatic phosphor layer (eg, a white light-emitting phosphor layer) 112 as a whole. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. On the one hand, according to the applicant's invention, the flat cathode wire tube 1 2 0 is shown in FIG. In addition to the first phosphor section 1 2 1 where the black-and-white video image is displayed, a second phosphor section 123 for color display is provided. The second phosphor section 123 is provided with a first phosphor section and a first phosphor section 123. The other phosphor layers 1 24 which emit light of different colors from the phosphor layer 122 of the body 121. The phosphor layers 1 24 are first patterned to imitate the shape of the image to be displayed. The phosphor layers of the second phosphor portion 1 23 1 24 This paper size applies to China National Standard (CNS) Α4 size (210 X 297 mm) 5- 5 83706 A7 B7 V.

When the second phosphor portion 1 23 is scanned with an electron beam, the phosphor pattern portion will emit light and become an image-like color image display. At this time, the second phosphor portion is displayed on the second phosphor portion. The light body portion 123 forms a plurality of phosphor patterns (image patterns) 124A, 124B, 124C, and a plurality of image images can be displayed simultaneously or individually.

Thereby, as shown in FIG. 5 (D), the adhesive layer 16 is vaporized and passed through the conductive layer 15, the reflective layer 14, and the first phosphor layer 13 to be removed from the screen 31 by the exhaust gas. A first phosphor portion 51 composed of a conductive layer 15, a reflective layer 14, and a first phosphor layer 13 is formed on the inner surface of the screen 32 as described above.

Description of the invention (15) on the conductive layer 15. Then, the second phosphor layer 23 and the reflective layer 24 are pasted on the conductive layer 15 at a position transferred to a position matching the formation region of the second phosphor portion 52. Next, the screen 31 is heated to a temperature at which the transfer substrate 21 is peeled off (for example, about 200 ° C). Thereby, as shown in FIG. 6 (B), the transfer substrate 21 peels off the second transfer film 2, and the transfer layer 20 is transferred to the inner surface of the screen 31 through the conductive layer 15. When the transfer substrate 21 is peeled off, the screen 31 is not heated, and the thermal transfer roller heated to a predetermined temperature (for example, 200 ° C to 25 (TC)) is pushed from the transfer substrate 21 side. Second, The screen 3 1 of the peeling transfer substrate 21 1 is heated to a temperature higher than the peeling temperature of the transfer substrate 21 (for example, about 300 ° C.). As a result, as shown in FIG. 6 (C), the peeling layer 22 is made. It is gasified and removed by the exhaust gas from the screen 31. After removing the release layer 22, the screen 31 is then heated to a temperature (for example, about 400 ° C to 485 ° C) at which the temperature at which the release layer 22 is vaporized. Thereby, as shown in FIG. 6 (D), the adhesive layer 26 is vaporized and removed from the screen 31 through the reflective layer 24 and the second phosphor layer 23. The inner surface of the screen 32 is formed by this. The second phosphor portion 52 made of the conductive layer 15, the reflective layer 24, and the second phosphor layer 23.

As long as this embodiment is used, the first The phosphor portion 51 and the second phosphor portion 52 are formed in another process by a transfer method using two transfer films 1 and 2 so that there is no image display for manufacturing. The conventional transfer film used in the normal flat cathode sponge tube 110 (Fig. 14 (A)) in the region 32B can still be used as the first transfer film 1. As a result, the fluorescent surface 50 is closed. The formation process can be achieved with the production line of the conventional flat cathode wire tube without the image display area 32B. The paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -18- 583706 A7 B7 V. Invention Explanation (16 points are common.

Second, by using the second transfer film 2 B The transfer method forms the second phosphor portion 5 2 (step S 1 2). At this time, the conductive layer 15A formed by the transfer using the first transfer film 1A partially overlaps the transfer of the second transfer film 2B. The printed layer, especially the conductive layer 25A, is used for transfer.

The conductive layer 25A is electrically connected to the inner conductive film 53 of the funnel portion 33 by using a conductive film 54 (step S14). The conductive conductive film 54 is formed in the same manner as in the case shown in FIG. 7, for example, from the central end portion of the conductive layer 2 5 A on the side of the funnel portion 33 to the center of the screen 31 of the internal conductive film 53. The end area is coated with, for example, a carbon film. The conductive conductive film 54 is fired at, for example, a temperature of about 440 ± 20C. The conductive conductive film 54 is formed so that the anode layer HA is applied to the conductive layer 25A of the second phosphor portion 52 through the internal conductive film 53 and the conductive conductive film 54.
