一實施例中，將刀體100的切刃邊緣(包括第一切刃邊緣202與第二切刃邊緣203)朝向光學膜材550之第二材料膜856，從第二材料膜856的膜表面856S沿第一方向D1往第一材料膜754向下進行沖壓裁切步驟。在裁切步驟期間，第一切刃邊緣202首先接觸第二材料膜856的膜表面856S，從而在光學膜材550切出第一切割線1202(以粗虛線表示)，且因為第一切刃邊緣202形成一封閉區域，所以第一切刃邊緣202所形成的第一切割線1202為一封閉的切割線；同時，在裁切步驟期間，第二切刃邊緣203接觸第二材料膜856的膜表面856S，從而在光學膜材550切出第二切割線1304(以細虛線表示)。第二切割線1304位於具有封閉分佈之第一切割線1202內的區域，且第二切割線1304與第一切割線1202相連接。從而，形成如第3圖所示的光學膜片2550，其中光學膜片2550為一可用於貼附顯示面板(圖未示)之光學片材產品。In one embodiment, the cutting edge of the cutter body 100 (including the first cutting edge 202 and the second cutting edge 203) faces the second material film 856 of the optical film 550, from the film surface of the second material film 856 In 856S, a stamping and cutting step is performed downward to the first material film 754 in the first direction D1. During the cutting step, the first cutting edge 202 first contacts the film surface 856S of the second material film 856, thereby cutting the first cutting line 1202 (indicated by the thick dashed line) in the optical film 550, and because the first cutting edge The edge 202 forms a closed area, so the first cutting line 1202 formed by the first cutting edge 202 is a closed cutting line; at the same time, during the cutting step, the second cutting edge edge 203 contacts the second material film 856 The film surface 856S, so that a second cutting line 1304 (indicated by a thin dashed line) is cut out in the optical film 550. The second cutting line 1304 is located in an area within the first cutting line 1202 having a closed distribution, and the second cutting line 1304 is connected to the first cutting line 1202. Thus, an optical film 2550 as shown in FIG. 3 is formed, wherein the optical film 2550 is an optical sheet product that can be used to attach a display panel (not shown).

其中，第一切刃邊緣202(或第一切割線1202)用以切割光學膜材550的所有厚度，能切斷最下層之第一材料膜754的全部，亦即從光學膜材550中切割出一光學膜片2550產品。Among them, the first cutting edge 202 (or the first cutting line 1202) is used to cut all the thickness of the optical film 550, and can cut all the first material film 754 of the lowermost layer, that is, cut from the optical film 550 Produced an optical film 2550 product.

第二切刃邊緣203(或第二切割線1304)用以切割光學膜材550的部分厚度，例如在本實施例中，不會完全切斷第一材料膜754，使得第一材料膜754藉由未被切割的部分而具有膜連續性質，而連接光學膜片2550之主膜部2570與次膜部2580。The second cutting edge edge 203 (or the second cutting line 1304) is used to cut part of the thickness of the optical film 550. For example, in this embodiment, the first material film 754 is not completely cut, so that the first material film 754 is The uncut part has a film continuous property, and the main film portion 2570 and the sub film portion 2580 of the optical film 2550 are connected.

在另一實施例中，第二切刃邊緣203(或第二切割線1304)可能會深及第一材料膜754之部分厚度，但不會切割至第一材料膜754的全部厚度，使得第一材料膜754藉由未被切割的部分而具有膜連續性質，而連接光學膜片2550之主膜部2570與次膜部2580。In another embodiment, the second cutting edge edge 203 (or the second cutting line 1304) may be deeper than part of the thickness of the first material film 754, but will not be cut to the entire thickness of the first material film 754, so that the A material film 754 has a film continuity through the uncut portion, and connects the main film portion 2570 and the sub film portion 2580 of the optical film 2550.

請參照第1A圖，接著，在裁切刀具73往上移動而脫離光學膜材550後，放料機構110釋放光學膜材550，使傳送機構120帶動光學膜材550繼續往傳送方向S1前進，直到光學膜材550未被裁切的部分位於裁切刀具73的刀體100的下方，放料機構110方固定住光學膜材550，再重複對光學膜材550未被裁切的部分進行裁切步驟。藉此對光學膜材550進行更多次裁切，以較大的產率獲得多數量的光學膜片2550。Please refer to Figure 1A. Next, after the cutting tool 73 moves upward to separate from the optical film 550, the unwinding mechanism 110 releases the optical film 550 so that the conveying mechanism 120 drives the optical film 550 to continue to advance in the conveying direction S1. Until the uncut part of the optical film 550 is located below the cutter body 100 of the cutting tool 73, the discharging mechanism 110 fixes the optical film 550, and then repeats the cutting of the uncut part of the optical film 550 Cut steps. In this way, the optical film material 550 is cut more times, and a larger number of optical film sheets 2550 are obtained with a larger yield.

其它實施例中，裁切刀具73的刀體100可以其它種刀刃排列設計的刀體取代。例如，裁切刀具73可使用諸如第2A圖所示的刀體100A，或第2B圖所示的刀體100B，藉其可在單一次的裁切步驟中同時裁切出複數個光學膜片2550。第2A圖與第2B圖中，以實線表示刀體具有第一切刃邊緣202的部分，以虛線表示刀體具有第二切刃邊緣203的部分。In other embodiments, the cutter body 100 of the cutting tool 73 may be replaced by cutter bodies with other blade arrangement designs. For example, the cutting tool 73 can use the knife body 100A shown in Fig. 2A or the knife body 100B shown in Fig. 2B, which can simultaneously cut out a plurality of optical films in a single cutting step. 2550. In FIGS. 2A and 2B, the solid line shows the part of the knife body with the first cutting edge 202, and the broken line shows the part of the knife body with the second cutting edge 203.

另一實施例中，裁切刀具73可使用如第2C圖所示的刀體100C，其與第1B圖所示的刀體100的差異在於，刀體100C的主刀部406為一開放式刀膜，具有一開放式開口，例如主刀部406具有ㄇ字型刀刃排列，開放式開口為ㄇ字型的開口。In another embodiment, the cutting tool 73 may use the cutter body 100C shown in FIG. 2C. The difference from the cutter body 100 shown in FIG. 1B is that the main knife portion 406 of the cutter body 100C is an open knife. The membrane has an open opening. For example, the main knife portion 406 has a U-shaped blade arrangement, and the open opening is a U-shaped opening.

請參照第3圖，光學膜片2550包括主膜部2570與次膜部2580。主膜部2570與次膜部2580由第一材料膜754上互相分離的偏光膜652定義，面積的最大的偏光膜652對應的部分為主膜部2570，偏光膜652其餘部分為次膜部2580。請參照第1B圖與第3圖，其中，主膜部2570可由主刀部406定義，次膜部2580可由次刀部508定義。主膜部2570的切割側表面由主刀部406的第一切刃邊緣4202與第二切刃邊緣203造成。次膜部2580的切割側表面由次刀部508的第一切刃邊緣5202與第二切刃邊緣203造成。主膜部2570與次膜部2580各包括偏光膜652、第一材料膜754與第二材料膜856。主膜部2570與次膜部2580的偏光膜652及第二材料膜856是彼此斷開，主膜部2570與次膜部2580的第一材料膜754是相連接，亦即光學膜片2550之主膜部2570與次膜部2580係藉由第一材料膜754互相連接。Please refer to FIG. 3, the optical film 2550 includes a main film portion 2570 and a secondary film portion 2580. The main film portion 2570 and the sub film portion 2580 are defined by the polarizing film 652 separated from each other on the first material film 754. The portion corresponding to the polarizing film 652 with the largest area is the main film portion 2570, and the remaining portion of the polarizing film 652 is the sub film portion 2580. . Please refer to FIGS. 1B and 3, where the main film portion 2570 can be defined by the main knife portion 406, and the secondary film portion 2580 can be defined by the secondary knife portion 508. The cutting side surface of the main film portion 2570 is caused by the first cutting edge 4202 and the second cutting edge 203 of the main knife portion 406. The cutting side surface of the secondary film portion 2580 is caused by the first cutting edge 5202 and the second cutting edge 203 of the secondary knife portion 508. The main film portion 2570 and the sub film portion 2580 each include a polarizing film 652, a first material film 754, and a second material film 856. The polarizing film 652 and the second material film 856 of the main film portion 2570 and the sub film portion 2580 are disconnected from each other, and the first material film 754 of the main film portion 2570 and the sub film portion 2580 are connected, that is, the optical film 2550 The main film portion 2570 and the sub film portion 2580 are connected to each other by the first material film 754.

一實施例中，如第4圖所示，可將本發明的光學膜片2550貼合於一顯示面板(圖未示)，貼合步驟可包括一第一撕除步驟，在該第一撕除步驟中，可先將主膜部2570的第二材料膜856撕除，以得到如第4圖所示的光學貼片3590。In one embodiment, as shown in Figure 4, the optical film 2550 of the present invention can be attached to a display panel (not shown), and the attaching step can include a first peeling step. In the removing step, the second material film 856 of the main film portion 2570 can be torn off first to obtain the optical patch 3590 as shown in FIG. 4.

一實施例中，光學貼片3590包括位於主膜部2570與次膜部2580的偏光膜652與第一材料膜754，及僅位於次膜部2580的第二材料膜856。此實施例中，第一材料膜754為表面保護膜，第二材料膜856為離型膜。偏光膜652的厚度可為80-100μm，例如82μm、或92μm、或97μm。第一材料膜754(表面保護膜)的厚度可為偏光膜652的厚度的0.5~1倍。第一材料膜754(表面保護膜)的厚度可為80~100μm，例如90μm、或95μm。因為偏光膜652的厚度較薄，第一材料膜754(表面保護膜)的厚度若過厚容易造成偏光膜652翹曲問題。第一材料膜754(表面保護膜)的厚度若過薄則會有第一材料膜754(表面保護膜)不易與偏光膜652藉由黏著層貼合的問題。第二材料膜856(離型膜)的厚度可為35-40μm，例如為38μm。第一材料膜754(表面保護膜)、偏光膜652與第二材料膜856(離型膜)的整體厚度可在205μm至230μm之間，例如為210μm。In one embodiment, the optical patch 3590 includes a polarizing film 652 and a first material film 754 located in the main film portion 2570 and the secondary film portion 2580, and a second material film 856 located only in the secondary film portion 2580. In this embodiment, the first material film 754 is a surface protection film, and the second material film 856 is a release film. The thickness of the polarizing film 652 may be 80-100 μm, for example, 82 μm, or 92 μm, or 97 μm. The thickness of the first material film 754 (surface protection film) may be 0.5 to 1 times the thickness of the polarizing film 652. The thickness of the first material film 754 (surface protection film) may be 80-100 μm, for example, 90 μm, or 95 μm. Because the thickness of the polarizing film 652 is relatively thin, if the thickness of the first material film 754 (surface protection film) is too thick, it is likely to cause warpage of the polarizing film 652. If the thickness of the first material film 754 (surface protection film) is too thin, there will be a problem that the first material film 754 (surface protection film) is not easily attached to the polarizing film 652 via the adhesive layer. The thickness of the second material film 856 (release film) may be 35-40 μm, for example, 38 μm. The overall thickness of the first material film 754 (surface protection film), the polarizing film 652 and the second material film 856 (release film) may be between 205 μm and 230 μm, for example, 210 μm.

請參照第5A圖及第5B圖。第5A圖繪示一實施例中光學裝置的俯視圖。第5B圖繪示光學裝置沿第5A圖之EF剖面線的剖面圖。一實施例中，可將光學貼片3590的主膜部2570的偏光膜652的第二偏光膜表面652S2貼合至光學基板960。一實施例中，光學基板960用作顯示面板之基板，例如為透明的玻璃基板或可撓性基板，並包括顯示區域960A與非顯示區域960P。一實施例中，光學基板960可為TFT基板、彩色濾光片基板或OLED基板。Please refer to Figure 5A and Figure 5B. FIG. 5A is a top view of the optical device in an embodiment. FIG. 5B shows a cross-sectional view of the optical device along the EF section line in FIG. 5A. In an embodiment, the second polarizing film surface 652S2 of the polarizing film 652 of the main film portion 2570 of the optical patch 3590 may be bonded to the optical substrate 960. In one embodiment, the optical substrate 960 is used as the substrate of the display panel, such as a transparent glass substrate or a flexible substrate, and includes a display area 960A and a non-display area 960P. In an embodiment, the optical substrate 960 may be a TFT substrate, a color filter substrate or an OLED substrate.

一實施例中，主膜部2570對應顯示區域960A。次膜部2580突出顯示區域960A，並可重疊顯示區域960A外側的非顯示區域960P。一實施例中，主膜部2570對應顯示區域960A。次膜部2580突出顯示區域960A，並可重疊顯示區域960A外側的非顯示區域960P，並突出光學基板960。In one embodiment, the main film portion 2570 corresponds to the display area 960A. The secondary film portion 2580 highlights the area 960A and can overlap the non-display area 960P outside the display area 960A. In one embodiment, the main film portion 2570 corresponds to the display area 960A. The sub-film portion 2580 highlights the display area 960A, can overlap the non-display area 960P outside the display area 960A, and protrude the optical substrate 960.

一實施例中，次膜部2580的側邊2580S在一方向(例如第二方向D2)上突出顯示區域960A的距離L介於0.5cm~5cm之間。一實施例中，距離L為至少0.5cm，可便於在後續第二撕除步驟中順利抓取並移除次膜部2580。另外，次膜部2580超過顯示區域960A的尺寸可控制在一尺寸上限(例如可為5cm以下)之內，可改善其在主膜部2570的偏光膜652黏貼過程中因次膜部2580長度過長造成干涉。請再參考第5B圖，當光學貼片3590貼合到光學基板960上時，一實施例中，因次膜部2580的第二材料膜856並未被撕除，所以次膜部2580的第二材料膜856在光學基板960與次膜部2580的偏光膜652之間，即黏著層(圖未示)並未露出，光學貼片3590之次膜部2580的第二材料膜856(例如為離型膜)與光學基板960之間不具黏性，可避免次膜部2580汙染光學基板960。In one embodiment, the distance L of the side 2580S of the secondary film portion 2580 to highlight the area 960A in one direction (for example, the second direction D2) is between 0.5 cm and 5 cm. In an embodiment, the distance L is at least 0.5 cm, which can facilitate smoothly grasping and removing the secondary film portion 2580 in the subsequent second tearing step. In addition, the size of the secondary film portion 2580 that exceeds the display area 960A can be controlled within an upper limit (for example, it can be less than 5 cm), which can improve the length of the secondary film portion 2580 during the pasting process of the polarizing film 652 of the main film portion 2570. Long cause interference. Please refer to Figure 5B again. When the optical patch 3590 is attached to the optical substrate 960, in one embodiment, the second material film 856 of the secondary film portion 2580 is not torn off, so the second material film 856 of the secondary film portion 2580 is not torn off. The second material film 856 is between the optical substrate 960 and the polarizing film 652 of the secondary film portion 2580, that is, the adhesive layer (not shown) is not exposed. The second material film 856 of the secondary film portion 2580 of the optical patch 3590 (for example, is There is no adhesion between the release film and the optical substrate 960, which can prevent the sub-film portion 2580 from contaminating the optical substrate 960.

請參照第6圖，一實施例中，可包括一第二撕除步驟，在第二撕除步驟中，操作員或抓取器件，例如機械手臂，可從光學貼片3590的次膜部2580進行抓取，並藉由次膜部2580的第一材料膜754與主膜部2570的第一材料膜754相連接的設置，在撕除次膜部2580時連帶將主膜部2570的第一材料膜754自主膜部2570的偏光膜652上撕除，而留下主膜部2570的偏光膜652覆蓋在光學基板960的顯示區域960A。Please refer to Fig. 6, in an embodiment, a second peeling step may be included. In the second peeling step, an operator or a grasping device, such as a robotic arm, can remove the optical patch 3590 from the secondary film portion 2580 The first material film 754 of the secondary film part 2580 is connected to the first material film 754 of the main film part 2570. When the secondary film part 2580 is torn off, the first material film 754 of the main film part 2570 is also removed. The material film 754 is torn off the polarizing film 652 of the main film portion 2570, leaving the polarizing film 652 of the main film portion 2570 to cover the display area 960A of the optical substrate 960.

請再次參考第5B圖，一實施例中，貼合於光學基板960上的主膜部2570與次膜部2580具有一因第二材料膜856產生之高度差，此高度差可使得主膜部2570與次膜部2580互相連接的第一材料膜754與主膜部2570的偏光膜652在撕除前就預先分離，預先分離在第二方向D2上的長度G例如可為1~2mm之間，且可經由抓取高度較高之次膜部2580降低撕除連接主膜部2570與次膜部2580之第一材料膜754的難度。長度G為主膜部2570的偏光膜652之第一偏光膜表面652S1與主膜部2570的第一材料膜754在撕除前就互相分離之處在第二方向D2上的長度。一實施例中，第一材料膜754可具有至少1/2的厚度未被切割，如此可避免第一材料膜754在撕除過程斷裂而無法完成撕除的情況。Please refer to FIG. 5B again. In one embodiment, the main film portion 2570 and the secondary film portion 2580 bonded to the optical substrate 960 have a height difference caused by the second material film 856. This height difference can make the main film portion The first material film 754 connected to the secondary film portion 2580 and the polarizing film 652 of the main film portion 2570 are separated before tearing off. The length G separated in the second direction D2 can be, for example, between 1 and 2 mm. , And the difficulty of tearing off the first material film 754 connecting the main film portion 2570 and the secondary film portion 2580 can be reduced by grasping the secondary film portion 2580 with a higher height. The length G is the length in the second direction D2 where the first polarizing film surface 652S1 of the polarizing film 652 of the main film portion 2570 and the first material film 754 of the main film portion 2570 are separated from each other before being torn off. In an embodiment, the first material film 754 may have a thickness of at least 1/2 that has not been cut, so as to avoid the situation that the first material film 754 is broken during the tearing process and the tearing cannot be completed.

此外，第二撕除步驟不需在第一材料膜754的表面上另外黏接撕除膠帶，可避免膠帶造成的生產費用，降低生產成本。In addition, the second tearing step does not need to additionally adhere a tearing tape on the surface of the first material film 754, which can avoid the production cost caused by the tape and reduce the production cost.

第7圖至第8圖繪示第二實施例之光學裝置的製造方法，其中第一實施例與第二實施例的不同在於第一撕除步驟、貼合步驟以及第二撕除步驟的不同。此實施例中，第一材料膜754為離型膜，第二材料膜856為表面保護膜。第一撕除步驟可改為將第3圖光學膜片2550的第一材料膜754撕除。在撕除第一材料膜754的過程中，先將偏光膜652的第一偏光膜表面652S1朝下，接著操作員或抓取器件，例如機械手臂，抓取光學膜片2550的次膜部2580並進行撕除，因次膜部2580的第一材料膜754與主膜部2570的第一材料膜754相連，所以在撕除次膜部2580時可連帶將主膜部2570的第一材料膜754自主膜部2570的偏光膜652上撕除，以得到如第7圖所示的光學貼片6590。值得注意的是，在第一撕除步驟就撕除第一材料膜754的實施例中，第一偏光膜表面652S1朝下，次膜部2580可因重力的作用而使得主膜部2570的第一材料膜754在被撕除前就預先與主膜部2570的偏光膜652分離，進而降低撕除難度。一實施例中，預先分離在第二方向D2上的距離可為1~2mm之間。Figures 7 to 8 show the manufacturing method of the optical device of the second embodiment, where the difference between the first embodiment and the second embodiment lies in the difference between the first peeling step, the bonding step, and the second peeling step . In this embodiment, the first material film 754 is a release film, and the second material film 856 is a surface protection film. The first tear-off step can be changed to tear off the first material film 754 of the optical film 2550 in FIG. 3. In the process of tearing off the first material film 754, first turn the first polarizing film surface 652S1 of the polarizing film 652 downward, and then the operator or grasping device, such as a robotic arm, grasps the secondary film portion 2580 of the optical film 2550 The first material film 754 of the secondary film portion 2580 is connected to the first material film 754 of the main film portion 2570. Therefore, the first material film of the main film portion 2570 can be removed when the secondary film portion 2580 is torn off. 754 is torn off the polarizing film 652 of the main film portion 2570 to obtain the optical patch 6590 as shown in FIG. 7. It is worth noting that in the embodiment where the first material film 754 is torn off in the first tearing step, the first polarizing film surface 652S1 faces downwards, and the secondary film portion 2580 can make the second film portion 2570 of the main film portion 2570 under the action of gravity. The material film 754 is separated from the polarizing film 652 of the main film portion 2570 before being torn off, thereby reducing the difficulty of tearing off. In an embodiment, the pre-separated distance in the second direction D2 may be between 1 mm and 2 mm.

請參照第7圖，光學貼片6590包括主膜部2570的偏光膜652與第二材料膜856。一實施例中，貼合步驟包括將光學貼片6590的偏光膜652的第一偏光膜表面652S1貼合至光學基板960的顯示區域960A。Please refer to FIG. 7, the optical patch 6590 includes the polarizing film 652 of the main film portion 2570 and the second material film 856. In one embodiment, the bonding step includes bonding the first polarizing film surface 652S1 of the polarizing film 652 of the optical patch 6590 to the display area 960A of the optical substrate 960.

一實施例中，第二材料膜856(表面保護膜)的厚度可為50-60μm，例如為55μm。偏光膜652的厚度可為80~100μm，例如82μm、或92μm、或97。第一材料膜754(離型膜)的厚度可為偏光膜652之厚度的0.5~1倍。第一材料膜754(離型膜)的厚度可為80~100μm，例如 90μm。第一材料膜754(離型膜)的厚度若過厚容易造成偏光膜652翹曲問題。第一材料膜754(離型膜)的厚度若過薄則會有第一材料膜754(離型膜)不易與偏光膜652藉由黏著層貼合的問題。第二材料膜856(表面保護膜)、偏光膜652與第一材料膜754(離型膜)的整體厚度可在205μm至230μm之間，例如為227μm。但本揭露不限於此。In an embodiment, the thickness of the second material film 856 (surface protection film) may be 50-60 μm, for example, 55 μm. The thickness of the polarizing film 652 may be 80-100 μm, for example, 82 μm, 92 μm, or 97 μm. The thickness of the first material film 754 (release film) may be 0.5 to 1 times the thickness of the polarizing film 652. The thickness of the first material film 754 (release film) may be 80-100 μm, for example, 90 μm. If the thickness of the first material film 754 (release film) is too thick, it is likely to cause warpage of the polarizing film 652. If the thickness of the first material film 754 (release film) is too thin, there will be a problem that the first material film 754 (release film) is not easily attached to the polarizing film 652 via the adhesive layer. The overall thickness of the second material film 856 (surface protection film), the polarizing film 652 and the first material film 754 (release film) may be between 205 μm and 230 μm, for example, 227 μm. But this disclosure is not limited to this.

請參照第8圖，一實施例中，該第二撕除步驟可改為包括將撕除膠帶962黏貼至光學貼片6590的第二材料膜856之上。操作員或抓取器件，例如機械手臂，可藉由撕除膠帶962自偏光膜652上撕除第二材料膜856，而留下偏光膜652覆蓋在光學基板960的顯示區域960A。Please refer to FIG. 8. In one embodiment, the second tearing step may instead include sticking the tearing tape 962 onto the second material film 856 of the optical patch 6590. An operator or a grasping device, such as a robotic arm, can tear off the second material film 856 from the polarizing film 652 by removing the tape 962, leaving the polarizing film 652 covering the display area 960A of the optical substrate 960.

本揭露並不限於以第1A圖、第1B圖所示之裁切機構及使用其進行裁切所得到之第3圖的光學膜片2550。第1B圖所示之裁切機構可使用其它種刀體，例如刀體可具有多個次刀部508設置在一主刀部406的不同位置。可利用此裁切機構對光學膜材550進行裁切得到如第9圖所示的光學膜片8550，包括四個次膜部2580在主膜部2570的不同位置。次刀部508與次膜部2580並不限如圖式所示數量與配置位置，其可視實際需求任意調變，例如次膜部2580的位置可視撕膜手順情況而定。The present disclosure is not limited to the cutting mechanism shown in FIGS. 1A and 1B and the optical film 2550 of FIG. 3 obtained by cutting using the cutting mechanism. The cutting mechanism shown in FIG. 1B can use other types of knife bodies. For example, the knife body can have a plurality of secondary knife portions 508 arranged at different positions of a main knife portion 406. The cutting mechanism can be used to cut the optical film 550 to obtain the optical film 8550 as shown in FIG. 9, including four sub-film portions 2580 at different positions of the main film portion 2570. The secondary knife portion 508 and the secondary film portion 2580 are not limited to the number and arrangement positions as shown in the figure, and can be arbitrarily adjusted according to actual needs. For example, the position of the secondary film portion 2580 can be determined according to the order of the tearing operation.

一實施例中，主刀部406與主膜部2570的配置可視光學基板960的顯示區域960A而定。例如主膜部2570可不限於矩形狀，而可具有圓形、橢圓形、酒桶形、其它多邊形、或其它顯示區域960A可能配置的形狀。In an embodiment, the arrangement of the main knife portion 406 and the main film portion 2570 may be determined based on the display area 960A of the optical substrate 960. For example, the main film portion 2570 may not be limited to a rectangular shape, but may have a circular shape, an oval shape, a barrel shape, other polygonal shapes, or other shapes where the display area 960A may be configured.

本揭露並不限於使用刀體的裁切機構對光學膜材550進行裁切。在另一實施例中，裁切機構可為雷射裁切機構，藉由控制光學膜材550上主膜部與次膜部之雷射切割深度，從而獲得光學膜片。例如，如第3圖所示的光學膜片2550的第一切割線1202是由較深的雷射切割深度造成，而光學膜片2550的第二切割線1304是由較淺的雷射切割深度造成。The present disclosure is not limited to using the cutting mechanism of the knife body to cut the optical film 550. In another embodiment, the cutting mechanism may be a laser cutting mechanism, and the optical film can be obtained by controlling the laser cutting depth of the main film portion and the secondary film portion of the optical film 550. For example, as shown in Figure 3, the first cutting line 1202 of the optical film 2550 is caused by a deeper laser cutting depth, while the second cutting line 1304 of the optical film 2550 is caused by a shallower laser cutting depth. cause.
