度が得られる。A9 Invention 1 In FIG. 1, pixels shining on the image receiving surface 2 of a cathode ray tube 1 pass through a group of transparent rods 3 and are emitted from the leading edge 4. Light rays are emitted from the leading edge of each transparent rod in a dot shape according to the screen of the image receiving surface 2. The group 3 of transparent bars is oriented to cover the frame 7, resulting in a continuous exit screen without a black frame. However, the front surface of the cathode ray tube is covered with a thick glass 5 as shown in FIG. 11, and the tip 31 of the transparent rod cannot approach the pixels 6, so there is an extra pixel 6a. The light beam from 6b also enters the tip 31 of the transparent rod, so that accurate resolution cannot be obtained. Therefore, as shown in FIG.
It is desirable to provide a small value. However, recently, as shown in FIG. 12, cathode ray tubes for color TVs are designed with a thick front glass 50, as is well known, and efforts are made to make the surface shape as flat as possible, approaching the shape of a flat plate. Contrary to the improvement in the technical level of color TV cathode ray tubes, the present invention ignores the odd shape and bulges the front glass. The inventors focused on the fact that even thin glass, such as that found in thermos flasks and fluorescent lamps, can withstand atmospheric pressure. It is applied to cathode ray tubes. FIG. 1 shows an example of this, and it is designed to bulge out more forward than the general product shown in FIG. 12, so that the bulge is, for example, three times that of the general product. As a result, the image in front of the glass is curved, resulting in an image that is extremely strange compared to current common sense. However, in the present invention, since it is shown to the audience through the transparent rod group 3, the length of the transparent rod 30 is adjusted so that it is short at the center of the glass 5 and gradually lengthens toward the periphery along the curved surface of the glass. Lengthen. As a result, the exit surfaces X...X can be made substantially flat. However, even if the above-mentioned means are executed, a clear image cannot be obtained.Means for obtaining a clear image will be described in detail in Example 1 below. B0 Invention 2 In Invention 1, the front glass of the cathode ray tube is significantly bulged as a means of making the glass thinner, making it easier to withstand atmospheric pressure, but in place of this means, Invention 2 makes the glass thinner. As a means, a glass member of the same type as a common color TV cathode ray tube is used. As the overall dimensions of the cathode ray tube are gradually reduced, the glass becomes thinner, and as shown in Figure 4, the thickness T of the front glass becomes approximately the same as the scanning line width W. Although not shown, it is better to use TOW. More preferably, cathode ray tubes of such dimensions are stacked one above the other in multiple stages. (24th) As a result, one cathode ray tube receiver has fewer scanning lines. In this case, a conventional shadow mask or the like may be used, a roughened shadow mask may be provided, or the shadow mask may be omitted as in the third aspect. The same symbols as in Example 1: 2.2o, 3.3o, 4°40.
5 is the same as in Example 1, and its explanation will be omitted. C0 Invention 3 When cathode ray tubes are stacked one on top of the other, if there are many cathode ray tubes, each cathode ray tube receiver will have fewer pixels. All you need is a three-color BGR horizontal drive.This is not only cheaper than a normal color TV cathode ray tube, but also allows the cathode rays to be 100% fluorescent without being blocked by a shadow mask. , and bright brightness can be obtained.

再び[Embodiment 1] Invention I Refer to Figs. 1 and 3 to 11. In Fig. 1, a group 3 of transparent rods 30 is arranged densely along the curved surface of the front glass 5 of a cathode ray tube, and adjacent The ends 4.40 of the transparent rods of the cathode ray tube are oriented towards each other. Contrary to current common sense, the front glass 5 of the cathode ray tube, which has bulged significantly, is formed to be thin, and the transparent rod 3° is the front glass 5.
It is short at the center and long at the periphery, and the injection surface
X is almost flat. To give an example regarding the thickness of glass, if the thickness of the glass is 3 mm, the apparent thickness will be the upper thickness (light rays passing through the glass will be refracted in the direction perpendicular to the glass surface and approaching the whale). , which appears thinner than it actually is) can be, for example, 1.5 mm depending on the viewing angle, and the resolution when used with a scanning line width of about 3 mm approaches the practical range. Figure 4 shows an example, and the thickness of the glass is 411IIe.
The apparent thickness of the upper glass is 2IIll, the width W of the scanning line is 41cm, the number of scanning lines is 100 (height 40cm),
Using five cathode ray tubes (top and bottom), it is possible to form a large screen approximately 2.2 meters in height. In this case, the diameter of the transparent rod 30 is thinner than the width of the scanning line, and in the figure, it is made one-fourth as thin. Making the transparent rod thinner does not involve any technical burden and has some effect on improving resolution. If technology permits, if it is possible to design a glass with thinner glass, or if the glass can be expanded to a larger extent to make it thinner, the resolution can be improved accordingly. In that case, the number of cathode ray tubes may be decreased by increasing the number of scanning lines of the cathode ray tubes by -. Compared to the case of optical fiber communication, the distance of the present invention is very close, and the material of the transparent rod may be flexible in terms of transparency, and one synthetic resin is sufficient. Examples of such close-range light transmission include five applications (including Utility Application No. 63-113925 filed earlier by the applicant of the present invention).
(hereinafter referred to as the prior application), we created a number of prototypes and confirmed their effectiveness. Although both prototypes are made of synthetic resin,
Fortunately, we were able to obtain a clear transmission beam due to the close distance. However, in the present invention, a prototype was produced according to the above-mentioned FIG. 1, but unfortunately, the image was blurred like a halation, lacked contrast, and became a dull black image. So, we conducted another experiment with the aforementioned prototype, and as expected, we were able to achieve clear light transmission. The inventors researched why the prototype model based on Figure 1 causes halation-like blur, thinking that if they could find out the cause, they would be able to obtain the same sharpness as the previous application. The resulting theory is described next. In FIG. 5, the transparent rod group 3 is a collection of individual transparent rods 30, and air E is filled between each transparent rod. If this state is considered as a side view, it will be as shown in FIG. The oblique light beam La entering from the cut surface 31 travels through the transparent rod while being totally reflected, which is the basic principle of optical fibers. However, the oblique light ray Lb incident from the air E travels in the diagonal direction as shown in the figure.The two travel along completely different optical paths.This phenomenon is harmless in the case of long-distance communication.
Light f! Lb diverges laterally and does not become an obstacle.
However, in the present invention, since the light beam Lb is emitted at a close distance, the light beam Lb becomes a halo-like scattered light H, blurring the outline of the screen,
Makes the black part cloudy. Since the cause was clarified as described above, the above-mentioned problem was resolved by the means shown in the following figures. (Fig. 7) A group of transparent rods 30 is uniformly heated to near the softening point, and pressure perpendicular to the axis is applied to deform the cross section as shown in Fig. 7. As a result, the presence of air in the entrance section becomes minimal. Also,
There is an advantage that the density of the transparent rod is increased and the light receiving area is increased. (Fig. 8) When the group 3 of transparent rods 30 is made into a so-called "composite yarn" state in which transparent rods 30 and black filaments 9 are mixed,
The light rays traveling through the air often collide with the black filament 9,
Light rays in the air are absorbed. (FIGS. 9 and 10) Black paint 32 is applied near the cut surface 31, and later polished to expose the cut surface 31 and finished as shown in FIG. 10. A black film may be attached instead of paint. In addition to the above, although not shown, the surface of the transparent rod 30 may be coated with a coating material as an optically separate body. The five-hole anti-diffusion means has been described above by way of example. In common with FIGS. 7 to 10, since the transparent rod 30 is an optical element, a cross section that looks like it was cut with scissors is not good. Especially, the incident side cut surface 31 (FIG. 6) is optically It needs to be finished on a smooth surface. The term "black" used in this text exemplifies a light blocking material and a light absorbing material. again

Even if transparent rods are made into a "bundle", each transparent rod must be optically separate, and it is not allowed to bond the transparent rods constituting this "bundle" to each other with an adhesive. Therefore, it is necessary to bind the separate transparent rods into a bundle, even if it is troublesome. However, the entrance surface has a large concave surface, and is unstable and prone to collapse when bundled. Therefore, as a means of forming a "bundle" without using an adhesive, this embodiment is constructed as follows. The group of transparent bars is formed by dividing into blocks like 3a, 3b, 3c, 3d, etc., and the blocks are tied together with a band 8 to form one block B as shown in Fig. 3. . The blocks B are stacked in multiple stages to form an exit surface X as shown in FIG. An example of the manufacturing method for block B will be explained. The transparent rod 30 is preferably made of a synthetic resin with a high refractive index, which is melt-spun and stretched into a bundle, heated uniformly on the incident side to near its softening point, and compressed with a band 8 to infuse air. The root of the transparent rod group 3 is deformed as shown in FIG. 7, and its cross-sectional area is reduced, forming a transparent rod group that widens toward the end. The entrance surface 200 is formed into a concave surface that can approach the spherical surface of the cathode ray tube. In order to make this concave surface optically smooth, a transparent thin film is attached using a transparent adhesive. If the film is thick, the image will be distorted. Stack the desired number of blocks B, add a band to connect each block if necessary, glue each block, trim the injection side along mx...X, and cover the 3° cut surface with a transparent layer. Attach it to the TV with adhesive.)

方がよい。[Embodiment 2] FIG. 2 Similarly to Embodiment 1, a group 3 of transparent rods 30 is densely provided along the curved surface of the front glass 5 of the cathode ray tube, and the tips 4 of the transparent rods of adjacent cathode ray tubes are .40 are arranged in a direction approaching each other. The difference from Embodiment 1 is that the cathode ray tube is made smaller as a means of making the glass thinner, resulting in a large number of cathode ray tubes being stacked one above the other. For example, the scanning line width W is 4 mm, and the height of the large screen is approximately 2.2 mm.
m, if cathode ray tubes are stacked 10 times above and below, cathode ray tubes -
Each receiver is required to have 50 scanning lines, and the glass thickness T must be approximately that of four cabinets. If possible, it is desirable to use TOW to improve resolution. If there is a limit to the thickness T of the glass and it cannot be made thinner, increase the number of stacks (for example, 15) to make a screen with a height of 3.3 m. The scanning lines will be 6III11, and the thickness of the glass will be 6 cm. However, as mentioned above, it is desirable that T<W be close to the practical range. The halation-like blur prevention means and transparent rod binding means described in the first embodiment are also common to the second invention. Also invention 1
Similarly, it is better to make the diameter of the transparent bar thinner than the scanning line width.

る。[Example 3] When stacking cathode ray tubes one above the other, if there are many,
- The cathode ray tube receiver has fewer pixels, and in that case the cathode ray tube can have coarse scanning lines and be simple without a shadow mask. In this case, the fluorescent surface is formed into horizontal stripes of three colors BGR. This concludes the explanation of each embodiment corresponding to each claim. The explanation was given in the vertical direction, but the same applies to the horizontal direction. The following reference examples are not related to the above claims. (Reference Example 1) In the methods of Examples 1 to 30 described above, each cathode ray tube is only a part of a large screen, and the time when the remaining part is scanned is wasted as "waiting time". . Therefore, it is a good idea to install a circuit to store the signals necessary for the cathode ray tube among the signals on the large screen, and then to play back and repeat the stored signals during the above-mentioned waiting time. The cumulative lighting time of the screen increases and the screen appears brighter. In this case, the same effect can be obtained by slowing down the playback speed instead of repeating the process repeatedly. (Reference Example 2) Although the image receiving device is described as a cathode ray tube in Claim 1, Claim 2, and each embodiment, a large screen with inconspicuous seams can be obtained even if a liquid crystal image receiving device is used instead of the cathode ray tube. .
