See also Fig. 2, be a kind of manufacturing method of light conducting board that the present invention proposes, and please cooperate and consult Fig. 3 to shown in Figure 8, this manufacture method includes following step:
S1: prepare an optical element sheet 30, it is to have opposite first 301 and second surface 302.S2: cloth operation, earlier on the first surface 301 of optical element sheet 30 attached leaded light sclerosis coatings 40a, it is the mixture layer that acryl resin (Acrylate), ethoxy-propionic acid second fat (EEP), butanone (MEK), isopropyl alcohol (IPA), silicon dioxide (SiO2) and light initiator (Photoinitatorblend) mix mutually.
Wherein, above-mentioned components and concentration scope and numbering, can be as shown in the table:
| Composition | Concentration range | U.S. chemical abstract society numbering |
| Ethoxyl ethyl propionate | 2-10％ | 763-69-9 |
| Butanone | 2-10％ | 78-93-3 |
| Isopropyl alcohol | ?2-10％ | 67-63-0 |
| Acryl resin | ?80-95％ | 3524-68-3 |
| Silicon dioxide | ?2-10％ | 15468-32-3 |
| The light initiator | ?2-10％ | ---- |
S3: the oven dry operation, 40a is dried with the sclerosis of the leaded light on the first surface 301 coatings.
S4: utilize the leaded light sclerosis coatings 40a on 2 pairs of first surfaces 301 of an impression die to impress, the lower surface of impression die 2 is to be provided with leaded light micro structured pattern 21, makes the leaded light sclerosis coatings 40a on the first surface 301 form leaded light micro structured pattern 401a by impression.
S5: remove impression die 2, away from optical element sheet 30.
S6: be cured operation, utilize the leaded light sclerosis coatings 40a on ultraviolet (UV) the light L irradiation first surface 301, make its curing molding and be bonded to first surface 301.
After leaded light sclerosis coatings 40a solidifies, can carry out the step of S7: counter-rotating optical element sheet 30, make second surface 302 counter-rotatings be positioned at the top, make first surface 301 be positioned at the below relatively then.
Then, carry out the step of S8 again: operation to carry out a substandard cloth again, on second surface 302 again the leaded light formed with another and the first surface 301 same mixture coatings 40b that hardens.
S9: the oven dry operation, again the sclerosis of the leaded light on the second surface 302 coatings 40b is dried.
S10: utilize impression die 2 again the sclerosis of the leaded light on the second surface 302 coatings 40b to be impressed once more, make the leaded light sclerosis coatings 40b on the second surface 302 form leaded light micro structured pattern 401b.
S11: remove impression die 2 once more, away from optical element sheet 30.
S12: be cured operation once more, utilize the leaded light sclerosis coatings 40b on the ultraviolet light L irradiation second surface 302, make its curing molding and be bonded to second surface 302, promptly make light guide plate 3.
In addition, in being cured the step S6 of operation, above-mentioned ultraviolet light L penetrated optical element sheet 30 from lower to upper, and exposed to the leaded light sclerosis coatings 40a on the first surface 301, made its curing molding.
Equally, be cured among the step S 12 of operation at another, ultraviolet light L also penetrated the leaded light sclerosis coatings 40a and the optical element sheet 30 of the first surface 301 that is positioned at the below from lower to upper, exposed to the leaded light sclerosis coatings 40b of the second surface 302 that is positioned at the top, made its curing molding.
In addition, the leaded light micro structured pattern 21 of above-mentioned impression die 2 can be hit in the end face that impresses die 2 by laser light and be formed, so can form miniature leaded light micro structured pattern 21.
In the present invention, optical element sheet 30 is in order to import the light from light source, make the light conversion direction make it inject leaded light sclerosis coatings 40a, 40b from first, second surface 301,302, with equalizing light rays, light is evenly penetrated by leaded light micro structured pattern 401a, 401b on it.Under preferable material was selected, optical element sheet 30 can be selected for use as polymethylmethacrylate (Polymethyl Methylacrylate; PMMA), thermoplastic polyurethane (TPU), polycarbonate (PC), polyethylene terephthalate (PET) and silica gel (Silicone) one of them, but also can select other known material for use.
Please join Fig. 9 and shown in Figure 10 again, and please cooperate shown in Figure 8.The present invention more proposes a kind of light guide module, it is that set of applications is loaded on the outside of an e-book 7, can be being assembled on the e-book 7 of raising and cover, at least include a framework 5, most and arrange the luminescence component 6 be located in the framework 5, and above-mentioned light guide plate 3, one side end of light guide plate 3 is embedded in the framework 5, the light that luminescence component 6 is produced can be injected in the optical element sheet 30 of light guide plate 3, and by the leaded light on first, second surface 301,302 sclerosis coatings 40a, 40b equalizing light rays is penetrated, to illuminate the display frame of e-book 7.In addition, leaded light micro structured pattern 401a, 401b can be stipple pattern, and the site of stipple pattern and the density variation that can be directly proportional with the distance of the limit end of optical element sheet 30 and luminescence component 6, that is become big gradually away from the site of the stipple pattern of optical element sheet 30 these limit ends and luminescence component 6 gradually and density becomes close, use making directive become darker light to reach the light of homogenising with light nearby at a distance through closeer site.On the other hand, 6 of luminescence components can be light emitting diode.
Yet, composition by leaded light sclerosis coatings 40a, 40b in the above-mentioned explanation, behind its curing molding the characteristics that have high printing opacity, lead optical activity, and thickness is then reached about about 0.1mm, so on optical element sheet 30, present the performance of transparence, see the sharpness of looking e-book 7 pictures to avoid the having influence on user, and via under the above-mentioned manufacture method, leaded light sclerosis coatings 40a, 40b have the intensity that promotes set, preventing that it from having the problem that is easy to come off, and have good optical property, be easy to manufacture.Especially be applied on the e-book, have the situation that directly touches light guide plate because of the user, if under the situation of set undercapacity, then the light guide structure on the light guide plate easily produces and comes off, under the process operations of right the present invention by the composition of leaded light sclerosis coatings 40a, 40b and drying, impression, curing etc., then make light guide structure have the effectiveness of difficult drop-off, promptly have wear-resisting and scratch resistant effect.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
