The operation and effect between the above-described respective constitutions will be described.

An optical fiber plate manufacturing method according to an embodiment of the present invention will be described with reference to an optical fiber plate manufacturing apparatus 100 according to an embodiment of the present invention.

First, the optical fiber 210 supplied from the supply wheel 130 is coupled to a clamp 118 provided on one of the pair of alignment rolls 120 to wind the optical fiber 210.

When the optical fiber 210 is coupled to the alignment roll 120, the support rotation mechanism is operated to wind the optical fiber 210 spirally around the pair of alignment rolls 120 (see FIG. 3).

At this time, when the alignment roll 120 is rotated by the roll support 115 so that the optical fiber 210 is wound spirally around the pair of alignment rolls 120, And the length of the optical fiber 210 is adjusted by adjusting the distance between the alignment rolls 120 by the roll support 115.

When the optical fiber 210 is wound on the pair of alignment rolls 120, the pressing plate 151 is pressed to the side wall of the optical fiber receiving case 160 by the driving cylinder (see FIGS. 4 and 5).

Here, the optical fiber 210 may be coated with the bonding liquid by the bonding liquid application unit 190, or may be coated with the bonding liquid on the optical fiber 210 in a state where the optical fiber 210 is wound.

When the bonding liquid is a UV curing resin, the UV lamp 170 is operated in a state in which the optical fiber 210 wound on the pressing plate 151 is pressed, so that the optical fibers 210 are adhered do.

The optical fibers 210 wound on the alignment roll 120 are arranged such that the optical fibers 210 positioned in front of and behind the alignment roll 120 are shifted from each other by the guide grooves 121, , The optical fibers 210, or may be arranged in a single row (see FIG. 6)

6 (b), when the optical fibers are arranged in two rows such that the optical fibers are partially overlapped, the optical fibers may be arranged in a lattice form so as to transmit the image in such a manner as to match the pixels of the display panel per one optical fiber. ), When the optical fibers are arranged in a line, the gap between the optical fibers is minimized so that more optical fibers can transmit light.

On the other hand, when the pressing plate 151 presses the wound optical fiber 210, the optical fiber winding unit 110 moves laterally by the unit moving mechanism to separate the alignment roll 120 from the wound optical fiber 210 (See FIG. 2).

At this time, in a state where the optical fiber 210 is wound on the alignment roll 120, since the alignment roll 120 is not easily released laterally, the distance between the alignment rolls 120 in the roll support 115 is slightly reduced The fixing jig 117 moves in a direction opposite to the aligning roll 120 so as to correspond to the aligning roll 120.

When the aligning roll 120 is released from the optical fiber 210, the optical fiber winding unit 110 is moved forward of the pressing plate 151 and the optical fiber 210 is wound around the aligning roll 120 again .

When the optical fiber winding unit 110 in which the optical fiber 210 is wound is moved to the position where the optical fiber 210 pressed by the pressing plate 151 is moved, the plate moving mechanism 157 is operated again, The plate 151 is set up.

The optical fiber 210 wound on the optical fiber winding unit 110 is laminated on the optical fiber 210 previously accommodated in the optical fiber receiving case 160 in such a manner that the optical fiber 210 is again pressed by the pressing plate 151.

When the upper and lower ends of the optical fiber bundle are cut, the upper and lower ends of the optical fiber bundle are cut so that the optical fiber plate 200 has a desired height, or the upper and lower ends of the optical fiber bundle are cut, As shown in FIG.

The cut optical fiber bundle may be formed by polishing the entire outgoing surface so that the outgoing surface has a rough surface so that the light incident on the incident surface is diffused and emitted or the light emitted through the irregular outgoing surface by the cut is uniform A uniform surface layer can be formed as a whole on the emission surface so as to be diffused and emitted.

Here, the polishing process can be roughened by a wet process by a mechanical method or a wet process by a chemical process, and the incident surface may also be polished so that incident light diffuses and is incident thereon.

Further, when forming the uniform surface layer, a uniform surface layer can be formed in such a manner that the entire surface of the exit surface of the optical fiber plate 200 is coated with a uniform surface layer and cured, and the uniform surface layer can be an optical adhesive or an optical coating agent have.

The uniform surface material is formed of a material having the same refractive index as that of the optical fiber 210, and uniformly refracts the light diffused by the rough surface to provide a clear image.

 The uniform surface material may be formed of a material having the same refractive index as that of the optical fiber 210.

On the other hand, the exit surface on which the polished surface and the uniform surface layer are formed may have a haze value of 0.1% to 1% or a glass value of 95% to 98%.

Here, the optical fiber 210 normally has a viewing angle of 120 DEG at the center of the emitting surface. When a polishing process or a uniform surface layer is formed, a viewing angle of 180 DEG can be secured due to the diffusion of light.

9 (b), the optical fiber plate 200 may be formed by cutting an optical fiber bundle into a shape to be fabricated, cutting a bundle of optical fibers by a predetermined height, and joining a plurality of optical fiber bundles have.

The optical fiber plate 200 manufactured as described above has an annular shape, for example, when an optical fiber plate 200 is attached to a display panel, the upper or lower end of the optical fiber plate 200 is an incident surface or an emission surface, A surface in the opposite direction becomes an exit surface, and an image is displayed on a surface that is further projected from the surface of the display panel by a height of the optical fiber plate 200, so that a stereoscopic effect can be given to the image.

At this time, if the optical fiber plate 200 has the same diameter as the diameter of the optical fiber and is arranged in a lattice form (see FIG. 6C) in one row, it can match the pixel to provide a clear image, (See FIG. 6 (b)) so as to partially overlap with each other, so that the space between the optical fibers is minimized, so that more images can be outputted to the emission surface.

Therefore, the optical fiber plate manufacturing apparatus 100 according to the embodiment of the present invention can easily fabricate the optical fiber plate 200, and the optical fiber 210 having the uniform quality image can be displayed by uniformly arranging the optical fibers 210 ) Can be produced.

Further, the optical fiber plate 200 may be polished or a uniform surface layer may be formed to enlarge the viewing angle of an image to be emitted.
