Bending; a plurality of fixing pieces 28 are extended on the inner side surface of the light guide plate 22, and fixing holes 280 are provided at the near ends of each fixing piece 28.

As shown in FIGS. 5 to 7, the light guide plate unit 20 is assembled with a plurality of strip-shaped assembly clips 30 inside the light guide plate 22 to assemble the ends of the optical fibers 40. The assembly clips 30 are provided with convex ends 32 at equal intervals. A perforation 34 is provided on each convex end 32. The end of the optical fiber 40 can be assembled into the perforation 34 of each assembly clip 30 during assembly, and then the long assembly clip 30 is combined with the light guide plate 22. The inner side forms a light guide plate unit 20. It can be seen in FIG. 8 that one end of the perforation 34 adjacent to the convex end 32 is a funnel-shaped outer cone mouth 342 which is large and small inside, and the other end is also a funnel-shaped inner cone which is large and small inside. The mouth 340, when the end of the optical fiber 40 is assembled, passes the end of the optical fiber 40 from the inner cone opening 340 through the perforation 34. Due to the setting of the inner cone opening 340, the end of the optical fiber 40 can be properly guided when passing through. It is more convenient to penetrate the end of the optical fiber 40. Then, the end of the optical fiber 40 is heat-treated at the outer cone opening 342 to form a funnel end 400, so that the end of the optical fiber 40 and the assembly clip 30 can be firmly combined without being easily disengaged. Then, the end surface of the funnel end 400 is mirror-polished to form a smooth mirror-shaped end surface.

As can be seen in FIG. 8, an inner surface of the light guide plate 22 is provided with an assembling groove 24 through which the convex end 32 of the assembling clip 30 penetrates. The assembling groove 24 is slightly tapered, that is, the opening of the assembling groove 24 is large and inside. The convex end 32 of the corresponding assembly clip 30 is also slightly tapered, which is convenient for the convex end 32 to penetrate into the assembly groove 24. At the same time, a round convex surface is provided on the outer side of the light guide plate 22 corresponding to the assembly groove 24 26. It can provide proper diffusion of the light beam guided by the funnel end 400 of the optical fiber 40, and provide better viewing effects.

After the end of the optical fiber 40 penetrates into the perforation 34 of the assembly clip 30 to make a funnel end 400 and is mirror-polished, the convex end 32 of the assembly clip 30 can be bonded to the light guide plate in an adhesive, fusion, or close-fitting manner. 22 Positioning in the inner assembly groove 24. After the assembly clip 30 is fixed, the production of the light guide plate unit 20 is completed. Then, the light guide plate units 20 can be assembled and positioned in the outer frame 12, and appropriately bonded or It is locked, and the fixing rod 122 is passed through the fixing hole 120 and the fixing hole 280 on the fixing piece 28 of each light guide plate unit 20 to combine and position each light guide plate unit 20 and the outer frame 12 to complete the assembly of the entire display screen. .

As shown in FIGS. 9 to 10, the light guide plate 22 ′ can also be directly formed into a convex arc shape or a concave arc shape, and the assembly clip 30 ′ can also be made of elastic plastic or an appropriate material, and can When combined with the light guide plate 22, the inner side is deformed and combined according to the arc shape of the light guide plate 22 '. When the clip 30' and the optical fiber 40 are assembled, the light guide plate unit 20 'is assembled, as shown in Fig. 10 It is shown that the light guide plate 22 ′ of the light guide plate unit 20 ′ has an outwardly convex arc shape, whereby the light guide plate unit 20 ′ can be matched with a specific shape of the frame 12 ′ to form a frame as shown in FIG. 11. Non-planar optical fiber display, so that it can provide the needs of various environments, and improve the practical value of the optical fiber display.

It can be known from the above description that the present invention uses a light guide plate unit assembled in an outer frame to form a display screen. The light guide plate used in the light guide plate unit can be formed into a curved arc shape or formed into a curved arc shape by elasticity of the material itself. When the light guide plate unit is combined into a display screen, a non-planar optical fiber display can be formed. The light guide plates 2 2 shown in FIGS. 9 and 10 are convexly curved, so that they can be formed into a fiber optic display with a convexly semicircular curved surface as shown in FIG. 11, and they can even surround a whole circle. The cylindrical optical fiber display can be used to play special images to achieve special effects; of course, the light guide plate can also be made into a concave arc shape by the same technology, and then several light guide plates can be combined to form the same as shown in FIG. 12 The curved optical fiber display with a concave shape can even ring the optical fiber display to form a space, so that the viewer can experience different visual effects when placed in it. In addition, according to the design of the present invention, it can also be used as required. The light guide plate with convex curved surface and concave curved surface shape is appropriately matched to produce a wave-shaped optical fiber display similar to that shown in FIG. 13; of course, according to the technology and knowledge of the present invention, an appropriate arc can also be used. The light guide plate with a spherical arc shape can be made, so that an optical fiber display with a shape such as a convex spherical surface or a concave spherical surface can be assembled and matched, and it can show a distinctive effect more.

It can be known from technical common sense that the present invention can be implemented by other embodiments without departing from the spirit or essential characteristics thereof. Therefore, the above-disclosed embodiments are merely examples for illustration in every aspect, and are not the only ones. All changes that are within the scope of or equivalent to the invention are encompassed by the invention.
