擴散板是-種應用於電子產品的光學板，用於將光源 的光線擴散霧化，使螢幕呈現亮度均句之畫質，而不同電 子產品對於螢幕晝質需求不同，因此擴散板製造廠商製造 擴散板時，會依下游廠商之需求而製造出具有不同的光穿 透度的擴散板，該等擴散板的光穿透度雖然不同，但是外 觀皆呈現相同的薄片狀而難以分辨，當下游廠商不慎將不 同穿透度的擴散板弄混淆時，可以制—儀器測量擴散板 之穿透度，以區別出不同的擴散板。 然而，為了達到顯示器輕薄化、降低成本等目的，目 前有許多將顯示器模組中的擴散板之光擴散效果，以及增 免膜之集光效果整合成—光學板的開發研究。具有集光及/ 或光擴散效果的擴散板’其遠離光源之表面形成有多數個 微結構，所述微結構例如稜柱狀、弧突狀、金字塔狀等規 則花紋及/或不規則花紋等形狀，製造廠商亦是依下游廠商 需求而製造出各種具有不同微結構的擴散板。 具有微結構的擴散板在外觀上亦呈薄板狀其微結構 非常微小，目視不易進行區別，而且其光穿透度也約略相 同’如此就不能藉由儀器測量透光度來辨別，所以此種擴 201113597 散板製造完成後，會在其二個反向表面貼上保護膜，所述 保護膜一方面可以保護微結構，一方面可製作成不同顏色 來作為不同擴散板之間的區別辨識，因此下游廠商拿到擴 散板時，就可以藉由保護膜來辨別。 惟’貼上保護膜需要花費時間’同時會增加擴散板的 製造成本’為了降低製造成本，目前有許多製造廠商已取 消貼膜動作，但是如此卻增加下游裝配廠商區別不同擴散 板之困難性。 【發明内容】 因此，本發明之目的，即在提供一種具有標記圖案而 易於辨識的具微結構光學板及其標記製造方法。 於是，本發明具微結構光學板，其係具有複數個位在 該具微結構光學板之一表面的微結構，及至少一個位在該 光學板之另一表面的標記圖案，且該另一表面不具有微結 構或具有不規則花紋。 本發明具微結構光學板之標記製造方法，其係使該具 微結構光學板經過-表面具有一標記件之標記滾輪單元， 且該標記滾輪單元轉動使該標記件接觸該具微結構光學板 之表面’在該具微結構光學板表面形成一個對應該標記件 的標記圖案。亦可在具微結構光學板之表面喷塗—喷塗液 體’使該具微結構光學板之表面形成該標記圖案。 其中，本發明之具微結構光學板中，該等微結構 規則或不規則形狀’規則形狀如稜柱狀、金字m 狀等，可以是具有集光或者擴散光的功能，微^構之功& 201113597 =須加以限定；不規則形狀如表面作喷砂處理和作一般押 2者。料微結構係經由-個表面具微結構之滾輪及至少 一個表面溫度可調整之鏡面滾輪壓製而成。其製造方法為 板材由模頭押出後，穿過-個表面具微結構之滾輪及至少 -個表面溫度可調整之鏡面滾輪之間，使板材被具微結構 ^袞輪加壓，將滾輪表面上之微結構形狀以熱轉印方式壓 裝在板材上。可視需要，增加鏡面滾輪之數量 溫度作最佳的控制。 μ 本發明較佳之實施方法，係可於線上生產過程中就 一併進行標記作業，使該具微結構光學板之其中—表面具 有該標記圖案，標記圖案可以是壓印方式形成，也可以是 以液體塗布形成，標記圖案之型態不須限定。上述方法可 以與原生產線設備配合，並且具有製程簡單方便之優點。 本發明之-最佳實施例，係在微結構壓製製程中最末 端的鏡面滚輪上黏貼本發明之標記件，鏡面滾輪之表面⑺ 度控制在90〜15(TC，當鏡面滾輪棘丨枯恤 衷輪轉動到使標記件接觸到板 材時，板材即被滾輪加麼而形成凹陷之標記圖案其凹陷 深度為H)〜3〇“m’更佳為2〇〜2〇〇"m，最佳為5〇〜、 m ° μ 該標記件厚度為20~2000师，更佳& 3〇〜刚〇叫最 佳為40〜爾㈣。其材質可為聚亞胺類之防焊膠帶、聚四氣 W膠帶，或聚四氟乙稀與玻璃纖維摻混之勝帶，利用其 背面之背膠而黏結於鏡面滾輪之表面，該背膠及標圮件^ 身為耐熱材質’在高溫下不會融出，且同時具備耐熱性、 201113597 電氣特性、機械強度等特性者更佳。 本發明亦可將標記件設置在製程中之輸送滾輪及引取 滾輪上’該標記件之高度可為〜ίο麵，更佳$卜8 mm ’其高度如果太低不易將印記印上，太高則易影響板材輸 送所述標。己件之南度，是指標記件設置在該輸送滚輪或 引取滾輪之表面時，標記件之表面與滾輪表面之間的距離 田私。己件黏結在该等滾輪之表面上時，標記件的高度就 是指標記件的厚度，但是該等滾輪之表面也可以設置略微 凹陷的凹槽，供標記件嵌入貼合，此時標記件之局部低於 滾輪的表面，另-部分凸出於滾輪的表面，因此標記件局 部嵌入時，其高度是指標記件凸出部位的厚度。 設置在引取滾輪的標記件除了有高度限制外，為避免 引取滾輪施加的高壓太容易將標記件推下，標記件之設計 以具斜面構造較#，此種設計可以減低標記件被引取滚輪 撞落的力量。 设置在輸送滾輪及引取滾輪上之標記件可沾附一標記 液體，使標記件接觸該具微結構光學板之表面形成標記圖 案。該標記液體以透明無色為主，因此對於光學板無光學 影響的疑慮。標記液體可選自乾燥後的塗層與該具微結^ 光學板之反射率的差為〇·1〜3_0之液體，如果小於〇丨將無 法辨識，在0_1以上，即可以肉眼辨識，例如抗靜電劑。乾 燥後的塗層與具微結構光學板之反射率的差大於3 〇則影^ 光學性質，此種液體例如WD40防銹劑或丙酮等。亦可^ 用具有紫外光顯色作用之化合物’其在可見光範圍為無色 201113597 ’在可見光區外則可顯色，以πν本U〜 M UV先照射後可產生藍光或紅The diffuser is an optical plate used in electronic products, which is used to diffuse and atomize the light of the light source, so that the screen has a brightness uniformity, and different electronic products have different requirements for the screen quality, so the diffusion board manufacturer manufactures When diffusing the plate, diffusing plates with different light transmittances are produced according to the requirements of downstream manufacturers. Although the light transmittance of the diffusing plates is different, the appearances are all the same in the form of flakes and difficult to distinguish. When the manufacturer accidentally confuses the diffusion plates of different penetrations, the instrument can measure the penetration of the diffusion plate to distinguish different diffusion plates. However, in order to achieve the purpose of lightening and thinning the display, reducing the cost, etc., there are many developments in which the light diffusing effect of the diffusing plate in the display module and the light collecting effect of the film are integrated into the optical plate. A diffusing plate having a light collecting and/or light diffusing effect is formed with a plurality of microstructures on a surface away from the light source, such as a regular pattern such as a prismatic shape, an arcuate shape, and a pyramid shape, and/or an irregular pattern. Manufacturers also manufacture a variety of diffusers with different microstructures according to the needs of downstream manufacturers. The diffusing plate with microstructure has a thin plate shape in appearance, and the microstructure is very small, and it is difficult to distinguish by visual observation, and the light transmittance is also about the same. Thus, it cannot be discriminated by measuring the transmittance by the instrument, so Expansion 201113597 After the production of the bulk board is completed, a protective film is attached to the two opposite surfaces thereof, and the protective film can protect the microstructure on the one hand, and can be made into different colors on the one hand as the difference between the different diffusion plates. Therefore, when the downstream manufacturer gets the diffusion plate, it can be distinguished by the protective film. However, it takes time to attach the protective film and increase the manufacturing cost of the diffusion plate. In order to reduce the manufacturing cost, many manufacturers have eliminated the filming action, but this has increased the difficulty for downstream assemblers to distinguish different diffusion plates. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a microstructured optical sheet having a marking pattern that is easily identifiable and a method of manufacturing the same. Accordingly, the present invention has a microstructured optical plate having a plurality of microstructures on a surface of the microstructured optical plate, and at least one marking pattern on the other surface of the optical plate, and the other The surface does not have a microstructure or has an irregular pattern. The method for manufacturing a mark of a microstructured optical plate according to the present invention is such that the microstructured optical plate passes through a marking roller unit having a marking member on the surface thereof, and the marking roller unit rotates to contact the marking member with the microstructured optical plate. The surface 'forms a marking pattern corresponding to the marking member on the surface of the microstructured optical plate. The surface of the microstructured optical sheet may also be formed into the marking pattern by spraying a spray-coating liquid on the surface of the microstructured optical sheet. Wherein, in the microstructured optical plate of the present invention, the regular or irregular shape of the microstructures, such as a prismatic shape, a gold shape, or the like, may have the function of collecting or diffusing light, and the function of the micro-structure & 201113597 = Must be defined; irregular shape such as surface sandblasting and general deduction. The microstructure is formed by pressing a surface-structured roller and at least one mirror roller with adjustable surface temperature. The method is the following steps: after the plate is pushed out by the die, the plate is passed between the surface of the microstructured roller and at least one surface roller with adjustable surface temperature, so that the plate is pressed by the micro structure and the roller surface is pressed. The microstructure of the upper structure is press-fitted onto the board by thermal transfer. Increase the number of mirror rollers for optimal control as needed. The preferred implementation method of the present invention can be carried out in the on-line production process, so that the surface of the microstructured optical plate has the mark pattern, and the mark pattern can be formed by embossing, or It is formed by liquid coating, and the pattern of the marking pattern is not limited. The above method can be combined with the original production line equipment, and has the advantages of simple and convenient process. In a preferred embodiment of the present invention, the marking member of the present invention is adhered to the endmost mirror roller in the microstructure pressing process, and the surface of the mirror roller (7) is controlled at 90 to 15 (TC, when the mirror roller is sloppy When the wheel rotates to make the marking member contact the plate, the plate is added by the roller to form a concave marking pattern with a recess depth of H)~3〇"m' is better for 2〇~2〇〇"m, the most Good for 5〇~, m ° μ The thickness of the marking piece is 20~2000 division, better & 3〇~ just squeaking is best for 40~ er (4). The material can be polyimide soldering tape, The poly-four-gas W tape, or the PTFE and glass fiber blending belt, is bonded to the surface of the mirror roller by the adhesive on the back side. The adhesive and the standard member are made of heat-resistant material. It is better to have the heat-dissipating property, the electrical characteristics of 201113597, the mechanical strength, etc. The present invention can also set the marking member on the conveying roller and the take-up roller in the process. ~ίο面, better $卜 8 mm 'its height is too low to print on the mark If it is too high, it will affect the conveying of the standard. The south of the piece means that the marking member is placed on the surface of the conveying roller or the drawing roller, and the distance between the surface of the marking member and the surface of the roller is fixed. When the rollers are on the surface of the roller, the height of the marking member refers to the thickness of the marking member, but the surface of the roller may also be provided with a slightly concave groove for the marking member to be fitted and fitted, and the marking member is lower than the portion. The surface of the roller protrudes from the surface of the roller. Therefore, when the marker is partially embedded, the height is the thickness of the protruding portion of the marker. The marker provided on the roller is not limited by height, in order to avoid the roller. The applied high pressure is too easy to push the marking member down, and the marking member is designed to have a beveled configuration. This design can reduce the force of the marking member being knocked down by the take-up roller. The marking member disposed on the conveying roller and the take-up roller can be dipped. Attaching a marking liquid to make the marking member contact the surface of the microstructured optical plate to form a marking pattern. The marking liquid is mainly transparent and colorless, so for the optical plate The optical influence may be selected from the liquid after the drying and the difference between the reflectance of the microplate and the optical plate of 微·1~3_0, if it is less than 〇丨, it will be unrecognizable, above 0_1, ie It can be visually recognized, for example, an antistatic agent. The difference between the reflectance of the dried coating and the microstructured optical plate is greater than 3 〇, and the optical properties such as WD40 rust inhibitor or acetone can also be used. A compound with ultraviolet color development, which is colorless in the visible range 201113597 'color can be developed outside the visible light region, and can be blue or red after being irradiated with πν U U UV

The invention may also apply an antistatic layer to the surface of the microstructured optical plate before the microstructured optical plate passes the marking roller unit. When the marking roller unit rotates (4), the marking member contacts the antistatic layer, that is, The surface of the antistatic layer forms the marking pattern.

The microstructured optical plate will be finished as a finished product through cutting, chamfering, product, packaging, etc., and will not be described in detail due to these important points. The marking pattern 2 of the micro-structured optical plate 赞] is not easily observed in the general state, so the marking pattern 2 does not affect the optical properties of the microstructured optical lens. When the display is displayed, the mark pattern 2 will not have any doubts that are observed. Since the micro-structured optical plate 1G is manufactured in a large area, it is subsequently cut into small pieces. Therefore, the present invention forms a plurality of patterns 2' on the microstructured optical plate ig to make each piece of the optical after cutting. On the board, you can still have at least ^軚. Pattern 2, for identification. However, in practice, it is also possible to set only one marker/2 and only form one marker pattern 2 to achieve the marking purpose. Further, the order of the steps of the present invention is not limited to the present embodiment as long as the steps can be continuously performed. Referring to Figures 1 and 5, a second preferred embodiment of the method for manufacturing a mark having a microstructured optical sheet 10 of the present invention is substantially the same as the first preferred embodiment, and is not the same as the 201113597 in the manufacture of the optical sheet of the present embodiment. The apparatus 3 further includes: a tray 313 correspondingly disposed below the endmost conveying roller 312, the tray 313 containing a yellow phosphor solution as a marking liquid. The marking member 32 of the present embodiment is in the shape of a b-shaped sheet made of rubber material, and is disposed on the surface of the endmost conveying roller 312 and spaced apart from each other along the axial direction of the conveying roller 312. The height of the marking members 32 is 5 mm. In this embodiment, the marking manufacturing method of the microstructured optical plate 1 is used. When the softened body unit 1 is transported to the endmost conveying roller 312, the conveying roller 312 rotates to pick up the marking in the lower tray 313. The liquid 'make the marking members 32 adhere to the marking liquid when the conveying roller 312 is rotated to cause the marking members 32 to fit the body unit! In the case of the first surface (1), the first surface 111 is printed with the marking liquid adhered by the marking members 32, thereby forming a marking pattern 2 of a B-type such as a crucible, and completing the fabrication of the microstructured optical sheet 1' Moreover, each time the conveying roller 312 makes one rotation, the marking pattern 2 is printed at a corresponding spacing distance. The mark pattern f 2 is not easily observed in a general state, and only when the ultraviolet light illuminates the mark patterns 2, the phosphor material absorbs ultraviolet light and emits visible light, which can be observed as 'identifying different optical plates. use. Referring to FIG. 6, a third preferred embodiment of the present invention having a microstructured optical plate 1 is substantially the same as the first preferred embodiment, and includes: a body single: a plurality of marking patterns 2, and the difference Therefore, the body early 1 of the present embodiment further includes an antistatic layer 13 formed on the first face iu of the body n, and the marking patterns 2 are disposed on the surface of the antistatic layer 13. 12 201113597 Referring to Figures 6, 7, and 8, a third preferred embodiment of the method for manufacturing a mark of a microstructured optical plate i() of the present invention, and an optical plate manufacturing apparatus 3 therewith, omitting the second preferred embodiment The trays 313 (Fig. 5) are in the middle, and the markers 32 are disposed on the surface of the roller 314 at the extreme end. The marking manufacturing method of this embodiment comprises: (1) performing step 51: sticking the marking members 32 to the surface of one of the take-up rollers 314. (7) Performing Step 52·· This step is the same as the above-described first preferred embodiment for forming the body 11 and the microstructure 12, and therefore will not be described. (3) Steps 55: The body u having the microstructure 12 formed on the surface is in a softened state' is transported to the transport rollers 312_L, and is thus transported toward the downstream direction 4 of the line by the rotation of the transport rollers 312. (4) Performing step 56: coating the marking liquid, the marking liquid of the embodiment is an antistatic agent, and is applied to the first side (1) of the body crucible to form the antistatic layer 13. The antistatic layer 13 imparts an antistatic effect to the microstructured optical sheet to prevent dust particles from adhering to the surface of the microstructured optical sheet 10. It should be noted that, for convenience of illustration, FIG. 7 only shows the body unit 1 in a sheet shape, and each layer body is not separately illustrated. (5) performing steps 53, 54: the microstructured optical plate 1G is transferred between the extraction rollers 314, and the antistatic layer 13 is in an incompletely hardened state. The micro-structured optical plate 1 is rotated in the downstream direction, and the lead-in roller 314 is rotated, and the surface of the target member 32 is biased against the antistatic layer of the microstructured optical plate 1 The coating at the local position of the antistatic film 13 is wiped by the marking member 32 13201113597 to form a mark corresponding to the marking member 32, thus completing the fabrication of the micro-[o-shaped optical plate 10]. Further, as the bow picking up the roller continues to rotate, the micro-structured optical plate 1G has a plurality of rows of mark patterns 2 spaced apart. In some manufacturing processes of the optical plate, the antistatic layer 13 is coated as described in the embodiment to increase the protection of the optical plate. Therefore, in this embodiment, the marking pattern is formed on the antistatic layer 13 by using the force of the drawing roller 314. 2. The microstructured optical plate 10 is identifiable through the marking patterns 2. The body unit used in the present embodiment is an oxime methacrylate benzoate (MS), and its horizontal reflectance is 40.9' using a LAIK0 CO· LTD, Japan GR 225 machine. The nic surfactant acts as the antistatic layer 13, and after the drying thereof, the reflectance is 40.7, so that the coating at the local position of the antistatic layer 13 is wiped off by the marking member 32, and the marking pattern 2 is formed.反射.2 has a poor reflectance. Facing the micro-structured optical plate 10 and not observing the marking patterns 2, only when the microstructured optical plate 10 is rotated to a specific angle, the marking patterns 2 do not affect the The application of optical plates in displays. On the other hand, the manner and marking principle of this embodiment can also be similar to the second preferred embodiment, in which case it is not necessary to rely on the antistatic agent coated on the body U, but a tray containing the marking liquid is provided. Below the take-up roller 314, when the take-up roller 314 is rotated, the marking members 32 adhere to the marking liquid 'in the lower tray' and are printed on the first surface U1 of the body 11. That is, the embodiment has two methods in application: one can first apply the marking liquid to the first surface 111' of the body unit 1 and then wipe it with the marking member 32 to form the 14 201113597 marking pattern 2, and the other is The marking liquid is applied to the marking member & and the marking liquid can be transferred to the surface of the body unit 丨. Referring to Figures 7 and 9, it should be noted that in order to prevent the 5 pick-up roller from being called the high pressure, the marking member 32 is easily pushed off. The design of the marking member U is shown in the side view of Fig. 9, and the edge has a beveled configuration. , reducing the force of the target member 32 being pulled down by the take-up roller 314. Referring to Figures 1 and 10, a fourth preferred embodiment of the method for manufacturing a mark of a microstructured optical plate according to the present invention differs from the first preferred embodiment in that the optical plate manufacturing apparatus of the present embodiment 3 further includes a spraying unit 33 disposed at a position downstream of the drawing rollers 314, the spraying unit μ having a plurality of nozzles 331 spaced apart from each other, and the spraying unit 33 is provided with a yellow camping agent solution as a spraying liquid. In the method of the embodiment, after the main unit is driven by the take-up roller 314, the yellow phosphor solution is sprayed on the first surface (1) by the spraying unit to form a planar marking pattern 2 . Of course, the spacing, size and shape of the pattern can be controlled by the mouth coating device in conjunction with the stylized system. ^ The preferred embodiment above, in the online production process, can be combined to mark the job 'to make the micro-structured optical plate ίο - - m with the standard 2 can be matched with the original production line equipment, and has a simple process The advantage of convenience. A fifth preferred embodiment of the method for manufacturing a micro-structured optical sheet of the present invention, the optical sheet manufacturing apparatus I 3 further includes three belts 34 each connecting the transport rollers 312, the belt 34 is rotated by a motor that is not -, 屮^4, and drives the conveyor rollers 312 15 201113597 to rotate 'and the marking members 32 are disposed on the surface of the endmost belt 34' so that when the belt When the 34 is rotated to match the marking members 32 to the body unit 1 having the microstructured optical plate 10, the marking pattern 2 can also be stamped. Further, the belt provided for the marking member 32 may also be a belt for driving the rotation of the drawing rollers 314, so that the marking pattern 2 can also be embossed by the rotation of the belt. Referring to FIG. 12, a sixth preferred embodiment of the present invention having a microstructured optical plate 1 is different from the first preferred embodiment in that the first surface iu is provided with a plurality of irregular microstructures 14, The first surface is again made to have a surface having a regular pattern, and the marking patterns 2 are formed on the surface of the microstructures 14. However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention, All remain within the scope of the invention patent.
