Therefore, the optical fiber 100 is inserted into the plurality of grooves so that a flat arrangement having a flat and constant area is possible.

Step S2 (S2)

In the film coating part 6, the laminating films 61 and 62 are disposed on the upper and lower surfaces of the plurality of optical fibers 100 passing through the alignment part 4.

The film coating part 6 is composed of upper and lower rollers 63 and 64 circumscribed to the upper and lower parts.

The upper and lower rollers 63 and 64 are connected to a film supply unit (not shown) to which the laminating films 61 and 62 are supplied.

That is, the upper and lower rollers 63 and 64 are repeatedly raised and lowered by the elevating device 65 with a predetermined time difference so that the laminating films 61 and 62 are partially attached to the optical fiber 100. As described above, some of the optical fibers 100-2 are exposed to the outside without the laminating films 61 and 62 being coated.

The exposed optical fibers 100-2 are later bundled into a bundle to connect the light source 72 to the ends thereof.

The laminating films 61 and 62 may be selected from fabrics, papers, and synthetic resins, and have transparent or translucent and reflective properties.

In addition, the laminating films 61 and 62 are coated with an adhesive on one or both surfaces.

In addition, a high temperature laminating film or a low temperature laminating film may be applied.

The low temperature laminating film is operated at a temperature condition of room temperature or below room temperature, and the high temperature laminating film is operable at a temperature condition of 300 ° C. at room temperature.

Therefore, the low temperature laminating film is coated with more pressure-sensitive adhesive than the high temperature laminating film.

Step S3 (S3)

In the fusion unit 8, heat is applied to the outer surface of the laminating film assembly passing through the film coating unit 6 so that the upper and lower laminating films 61 and 62 are bonded while being melted.

A screen portion T for forming is formed, and the formed screen portion T for the optical fiber display module is stacked and accommodated in the storage portion 10.

The preferred cutting position cuts the point just before the exposed optical fiber 100-2 and the subsequent laminating films 61 and 62 meet.

The ends of the optical fibers 100-2 thus cut are bundled to form a bundle. Of course, you can have multiple bundles as needed.

Step 5 (S5)

By connecting the light irradiation unit 7 provided with the light source 72 to the end of the bundle of the plurality of cut optical fibers (100-2) to transmit the light.

The optical fiber completed through the manufacturing process is as shown in FIGS. 4 and 5.

That is, as shown in Figures 4 and 5, the screen portion (T) of the optical fiber display module manufactured according to the present invention is a laminating film on the top and bottom of the optical fiber 100 having a core 102 and a clad 104 (61,62) is coated to facilitate flexing, to prevent breakage or contamination, and to emit light.

Therefore, the optical fiber display module screen portion T manufactured according to the present invention can be applied as a backlight of an LCD, a display board, and the like.

6 is a view showing another example of the screen portion of the optical fiber display module according to the present invention.

As shown in FIG. 6, the screen part Ta of the optical fiber display module according to another embodiment of the present invention may apply an optical fiber 100a consisting of a core without a clad.

That is, since the laminating films (61, 62) is coated on the outside of the optical fiber 100a consisting only of the core, damage or contamination can be prevented, and the bending rate is good because the elongation is good, and particularly a separate scratch on the outer surface of the optical fiber Since it is not necessary to perform the forming process, the process can be shortened, thereby reducing manufacturing costs and improving luminance.

7 is a view showing another example of the optical fiber display module screen unit according to the present invention.

As illustrated in FIG. 7, the screen portion Td of the optical fiber display module according to the present invention may repeatedly process the coating and fusion processes of the laminating films 61 and 62 of the second step S2 and the third step S3. It is formed into a multilayer by carrying out.

That is, after the laminating films 61 and 62 are first coated on the outer surface of the optical fiber 100a, a plurality of optical fibers 100a are arranged on the upper surface of the screen portion T1, and then the laminating film 61 is disposed on the outer surface of the optical fiber 100a. The secondary coating to form a secondary screen portion (T2).

Similarly, after the optical fiber 100a is arranged on the secondary screen portion T2, the laminating film 61 is third coated to form the tertiary screen portion T3.

In this way, the coating operation of the multilayer optical fiber 100a and the laminating films 61 and 62 is performed.

In particular, the multilayer optical fibers 100a are alternately arranged so that interference between the upper and lower optical fibers does not occur.

8 and 9 are views illustrating an application example of the optical fiber display module screen unit according to the present invention.

As shown in FIG. 8, the screen portion Tb of the optical fiber display module according to the present invention may expand the light divergence area by arranging the optical fiber 100 by processing it in a partially curved form instead of arranging only the straight lines. And a specified shape can be expressed.
