本實施例中，第一光學膜材110係一光學膜捲料，纏繞於捲軸AX，在另一實施例中，第一光學膜材110亦可為一裁切後之光學膜片，本發明實施例不以此為限。第一光學膜材110包括第一黏合層111、第一匹覆層112、第一光學層113及第一保護層114。第一黏合層111黏合第一光學層113且與第一匹覆層112黏合。第一光學層113位於第一黏合層111與第一保護層114之間。雖然圖未繪示，然第一保護層114與第一光學層113可透過黏合層黏合。第一匹覆層112包括一層端部112a，層端部112a與第一黏合層111分離。在實施例中，第一匹覆層112之層端部112a以外的部分皆黏合於第一黏合層111上。第二光學膜材120可為一光學膜捲料或一光學膜片(光學膜捲料受到裁切後形成片狀光學膜片，此光學膜片例如可配置在一光學裝置，如顯示器中)，在本圖中僅顯示其膜片尾端部，第二光學膜材120包括膜片端部120a，膜片端部120a黏合在第一黏合層111上，且位於第一匹覆層112之層端部112a與第一黏合層111之間。如此，第二光學膜材120的整個膜片端部120a可透過第一光學膜材110之第一黏合層111黏接於第一光學膜材110中。詳言之，不需分離第二光學膜材120的任何二層，只要將第二光學膜材120的整個端部黏接在第一黏合層111上，即可接合第一光學膜材110與第二光學膜材120。In this embodiment, the first optical film material 110 is an optical film roll, which is wound on the reel AX. In another embodiment, the first optical film material 110 may also be a cut optical film. The present invention The embodiment is not limited to this. The first optical film 110 includes a first adhesive layer 111, a first coating layer 112, a first optical layer 113 and a first protective layer 114. The first adhesive layer 111 adheres to the first optical layer 113 and to the first coating layer 112. The first optical layer 113 is located between the first adhesive layer 111 and the first protective layer 114. Although not shown in the figure, the first protective layer 114 and the first optical layer 113 can be bonded through the adhesive layer. The first coating layer 112 includes a layer end 112 a, and the layer end 112 a is separated from the first adhesive layer 111. In the embodiment, the parts other than the layer end 112a of the first coating layer 112 are all adhered to the first adhesive layer 111. The second optical film 120 may be an optical film roll or an optical film (the optical film roll is cut to form a sheet-shaped optical film, and the optical film may be configured in an optical device such as a display, for example) In this figure, only the end of the film is shown. The second optical film 120 includes a film end 120a. The film end 120a is bonded to the first adhesive layer 111 and is located on the first coating layer 112. Between the end 112a and the first adhesive layer 111. In this way, the entire film end 120 a of the second optical film 120 can be bonded to the first optical film 110 through the first adhesive layer 111 of the first optical film 110. In detail, there is no need to separate any two layers of the second optical film 120, as long as the entire end of the second optical film 120 is bonded to the first adhesive layer 111, the first optical film 110 and The second optical film material 120.

如第1圖所示，可選擇性地再提供一黏合件130覆蓋第一匹覆層112之層端部112a與第二光學膜材120之第二匹覆層122，以更加固定層端部112a、第一光學膜材110與第二光學膜材120。黏合件130例如是膠帶。在實施例中，層端部112a位於黏合件130與膜片端部120a之間，黏合件130黏合層端部112a與膜片端部120a，可避免層端部112a與膜片端部120a隨意分離。在實施例中，第一匹覆層112可不具黏性。由於黏合件130黏合層端部112a與膜片端部120a，因此即使第一匹覆層112不具黏性，仍可穩定第一匹覆層112與第二光學膜材120之間的相對位置，避免第一匹覆層112之層端部112a隨意飄動。在一實施例中，視膜片端部120a的定義範圍及/或黏合件130的尺寸而定，黏合件130對於第二光學膜材120的黏合區域也可只包含膜片端部120a之一部分，或只包含膜片端部120a以外的部分，或同時包含膜片端部120a之一部分與膜片端部120a以外的部分。As shown in Figure 1, an adhesive 130 can optionally be provided to cover the layer end 112a of the first sheet coating layer 112 and the second sheet coating layer 122 of the second optical film 120 to more secure the layer end 112a, the first optical film material 110 and the second optical film material 120.

In an embodiment, the layer end 112a is located between the adhesive 130 and the film end 120a, and the adhesive 130 adheres the layer end 112a and the film end 120a to avoid the layer end 112a and the film end 120a being random Separate. In an embodiment, the first coating layer 112 may not have adhesiveness. Since the adhesive 130 adheres the layer end 112a and the film end 120a, even if the first mating layer 112 is not adhesive, the relative position between the first mating layer 112 and the second optical film 120 can be stabilized. Avoid random floating of the layer end 112a of the first cover layer 112. In one embodiment, depending on the definition range of the film end 120a and/or the size of the bonding member 130, the bonding area of the bonding member 130 to the second optical film 120 may also only include a part of the film end 120a , Or only include parts other than the diaphragm end 120a, or both include a part of the diaphragm end 120a and a part other than the diaphragm end 120a.

The second adhesive layer 121 adheres the second optical layer 123 and the second coating layer 122. The second optical layer 123 is located between the second adhesive layer 121 and the second protective layer 124. Although not shown in the figure, the second protective layer 124 and the second optical layer 123 can be bonded through the adhesive layer.

在一實施例中，第二光學膜材120例如是偏光膜，其中的第二光學層123例如是偏光層，而第二匹覆層122例如是離型層。第二光學膜材120之第二黏合層121、第二匹覆層122、第二光學層123及第二保護層124的材料分別同於或類似前述第一黏合層111、第一匹覆層112、第一光學層113及第一保護層114，且第二光學膜材120之第二黏合層121、第二匹覆層122、第二光學層123與第二保護層124的連接關係也同於或類似前述第一黏合層111、第一匹覆層112、第一光學層113與第一保護層114的連接關係，於此不再贅述。In an embodiment, the second optical film material 120 is, for example, a polarizing film, the second optical layer 123 is, for example, a polarizing layer, and the second coating layer 122 is, for example, a release layer. The materials of the second adhesive layer 121, the second cladding layer 122, the second optical layer 123, and the second protective layer 124 of the second optical film 120 are the same or similar to the first adhesive layer 111 and the first cladding layer, respectively 112, the first optical layer 113 and the first protective layer 114, and the connection relationship between the second adhesive layer 121, the second cladding layer 122, the second optical layer 123 and the second protective layer 124 of the second optical film 120 is also The connection relationship between the first adhesive layer 111, the first coating layer 112, the first optical layer 113, and the first protective layer 114 is the same as or similar to that described above, which will not be repeated here.

如第1圖所示，第二光學膜材120與第一光學膜材110係以層分布順序相同的方式接合。舉例來說，第一光學膜材110之數層沿一排列方向(如從外往內的方向)依序為第一匹覆層112、第一黏合層111、第一光學層113及第一保護層114，而與第一光學膜材110接合之第二光學膜材120的數層沿相同排列方向依序為第二匹覆層122、第二黏合層121、第二光學層123及第二保護層124。在此接合方式下，第二光學膜材120係以第二保護層124與第一黏合層111對接的方式黏接於第一光學膜材110中，而第一光學膜材110之第一匹覆層112係疊合在第二光學膜材120之第二匹覆層122上。As shown in FIG. 1, the second optical film material 120 and the first optical film material 110 are joined in the same manner as the layer distribution sequence. For example, the layers of the first optical film 110 are sequentially arranged along an arrangement direction (such as the direction from the outside to the inside) as the first coating layer 112, the first adhesive layer 111, the first optical layer 113 and the first The protective layer 114, and the layers of the second optical film 120 bonded to the first optical film 110 are sequentially along the same arrangement direction as the second coating layer 122, the second adhesive layer 121, the second optical layer 123, and the Two protective layer 124. In this bonding method, the second optical film 120 is bonded to the first optical film 110 by the second protective layer 124 and the first adhesive layer 111, and the first optical film 110 is The covering layer 112 is laminated on the second covering layer 122 of the second optical film 120.

此外，在實施例中，第一光學膜材110的長度可比第二光學膜材120長。在一實施例中，如第1圖所示，第二光學膜材120可以是用罄光學膜捲料之尾端殘料，而第一光學膜材110為另一完整的、新的、尚未使用或尚未裁切出光學膜片的光學膜捲料。透過本發明實施例的快速黏接方式，可將一光學膜捲料之尾端殘料快速地與另一光學膜捲料接合，以加速後續製程例如裁切製程，並減少材料的浪費。In addition, in an embodiment, the length of the first optical film 110 may be longer than that of the second optical film 120. In one embodiment, as shown in Figure 1, the second optical film material 120 may be the tail end of the spent optical film roll material, and the first optical film material 110 is another complete, new, unfinished Optical film rolls that are used or have not yet been cut out.

The diaphragm end 110 a is located between the layer end 122 a and the second adhesive layer 121. The bonding member 130 bonds the first optical film 110 and the layer end 122a.

在一實施例中，視膜片端部110a的定義範圍及/或黏合件130的尺寸而定，黏合件130對於第一光學膜材110的黏合區域也可只包含膜片端部110a之一部分，或只包含膜片端部110a以外的部分，或同時包含膜片端部110a之一部分與膜片端部110a以外的部分。In an embodiment, depending on the definition range of the film end 110a and/or the size of the bonding element 130, the bonding area of the bonding element 130 to the first optical film 110 may also only include a part of the film end 110a , Or only include parts other than the diaphragm end 110a, or both include a part of the diaphragm end 110a and a part other than the diaphragm end 110a.

A driver (such as a motor) is connected to the first holder 12 or the second holder 13 to drive the first holder 12 or the second holder 13 to rotate, thereby driving the optical film roll 120' to rotate. When the optical film roll 120' is used up, as shown in FIG. 3, the tail end material that can be used is cut from the optical film roll 120', such as the second optical film 120. Then, the spent optical film roll 120' can be detached from the driving device 10.

在本實施例中，在後續製程中，第二光學膜材120將與另一光學膜片或另一光學膜捲接合再利用，因此可最大化光學膜捲120’的使用率，減少材料浪費，且減少廢料量。In this embodiment, in the subsequent manufacturing process, the second optical film material 120 will be combined with another optical film or another optical film roll for reuse, so the utilization rate of the optical film roll 120' can be maximized and material waste can be reduced , And reduce the amount of waste.

然後，如第4A及4B圖所示，第4A圖繪示第一光學膜材110安裝在驅動裝置10的示意圖，而第4B圖繪示第4A圖之第一光學膜材110的側視圖。在本步驟中，提供第一光學膜材110。在本實施例中，第一光學膜材110例如是一完整的、一新的、未使用或尚未裁切出光學膜片的光學膜捲料，因此第一光學膜材110的長度可長於第二光學膜材120。第一光學膜材110捲繞於捲軸AX上。第一光學膜材110包括第一黏合層111、第一匹覆層112、第一光學層113及第一保護層114。然後，將第一光學膜材110安裝到驅動裝置10上，如第4A圖所示。相似地，驅動裝置10之第一固定器12與第二固定器13分別固定於捲軸13之相對二端，使當第一固定器12及第二固定器13轉動時，可帶動捲軸AX轉動，進而帶動第一光學膜材110進行送料或收料。Then, as shown in FIGS. 4A and 4B, FIG. 4A shows a schematic diagram of the first optical film 110 mounted on the driving device 10, and FIG. 4B shows a side view of the first optical film 110 in FIG. 4A. In this step, the first optical film material 110 is provided. In this embodiment, the first optical film 110 is, for example, a complete, new, unused or uncut optical film roll, so the length of the first optical film 110 may be longer than the first optical film.

The first optical film 110 includes a first adhesive layer 111, a first coating layer 112, a first optical layer 113 and a first protective layer 114. Then, the first optical film material 110 is mounted on the driving device 10, as shown in FIG. 4A. Similarly, the first holder 12 and the second holder 13 of the driving device 10 are respectively fixed at two opposite ends of the reel 13, so that when the first holder 12 and the second holder 13 rotate, the reel AX can be driven to rotate. In turn, the first optical film material 110 is driven to feed or receive.

然後，如第5A及5B圖所示，其繪示第5A圖之第一匹覆層112之層端部112a自第一黏合層111分離的示意圖。在本步驟中，分離第一匹覆層112之層端部112a與第一黏合層111。例如，以撕除方式，將第一匹覆層112之層端部112a自第一黏合層111撕離，以露出第一黏合層111。Then, as shown in FIGS. 5A and 5B, it shows a schematic diagram of the layer end 112a of the first coating layer 112 in FIG. 5A being separated from the first adhesive layer 111. In this step, the layer end 112a of the first coating layer 112 and the first adhesive layer 111 are separated. For example, by tearing off, the layer end 112a of the first coating layer 112 is torn away from the first adhesive layer 111 to expose the first adhesive layer 111.

然後，如第6A及6B圖所示，其繪示第5A圖之第一匹覆層112之層端部112a黏合第二光學膜材120的示意圖。第二光學膜材120包括第二黏合層121、第二匹覆層122、第二光學層123及第二保護層124。在本步驟中，黏合第二光學膜材120之膜片端部120a與第一黏合層111。例如，將第二光學膜材120的膜片端部120a接觸第一光學膜材110之第一黏合層111，使膜片端部120a黏接在第一黏合層111上。Then, as shown in FIGS. 6A and 6B, it shows a schematic diagram of bonding the second optical film 120 to the layer end 112a of the first coating layer 112 in FIG. 5A. The second optical film 120 includes a second adhesive layer 121, a second coating layer 122, a second optical layer 123 and a second protective layer 124. In this step, the film end 120a of the second optical film 120 and the first adhesive layer 111 are bonded. For example, the film end 120a of the second optical film 120 is in contact with the first adhesive layer 111 of the first optical film 110, so that the film end 120a is adhered to the first adhesive layer 111.

然後，如第7A及7B圖所示，其繪示第6A圖之層端部112a覆蓋第二光學膜材120的示意圖。在本步驟中，將第一匹覆層112之層端部112a覆蓋膜片端部120a的至少一部分，使膜片端部120a位於第一匹覆層112之層端部112a與第一黏合層111之間。Then, as shown in FIGS. 7A and 7B, it shows a schematic diagram of the layer end 112a of FIG. 6A covering the second optical film 120. In this step, the layer end 112a of the first mating layer 112 covers at least a part of the film end 120a, so that the film end 120a is located at the layer end 112a of the first mating coating layer 112 and the first adhesive layer Between 111.

然後，如第8圖所示，其繪示以第1圖之黏合件130黏合第7B圖之第一匹覆層112與第二光學膜材120的示意圖。在本步驟中，以黏合件130黏合第7B圖第一匹覆層112之層端部112a與第二光學膜材120之膜片端部120a，以固定層端部112a與第二光學膜材120的相對位置，避免層端部112a隨意飄動，而完成如第1圖所示之實施例中的光學膜片結構100。藉由本設計，可於後續的裁切製程前，先進行第一光學膜材110及第二光學膜材120的連接，使後續的裁切製程可連續生產而不中斷。此外，也可減少各別將每一捲光學膜捲架設及導入裁切製程機構中的時間及材料浪費。Then, as shown in FIG. 8, it is a schematic diagram of bonding the first coating layer 112 and the second optical film 120 of FIG. 7B with the adhesive 130 of FIG. 1. In this step, the layer end 112a of the first coating layer 112 in Figure 7B and the film end 120a of the second optical film 120 are bonded with the adhesive 130 to fix the layer end 112a and the second optical film. The relative position of 120 prevents the layer end 112a from floating randomly, and completes the optical film structure 100 in the embodiment shown in FIG. 1. With this design, the first optical film 110 and the second optical film 120 can be connected before the subsequent cutting process, so that the subsequent cutting process can be continuously produced without interruption. In addition, it can also reduce the time and material waste of setting up and introducing each roll of optical film into the cutting process mechanism.

如第2圖所示之實施例中的光學膜片結構200的接合方法類似前述光學膜片結構100的接合方法，不同處在於：第5B圖之第一光學膜材110之第一匹覆層112與第一黏合層111不需分離。然後，在第6B圖之步驟之前，以例如是撕除方式，分離第二光學膜材120之第二匹覆層122之層端部122a與第二黏合層121，以露出第二黏合層121。然後，對應第6B圖之步驟，黏合第一光學膜材110之膜片端部110a與第二黏合層121。然後，對應第7B圖之步驟，將第二匹覆層122之層端部122a覆蓋膜片端部110a的至少一部分，使膜片端部110a位於第二匹覆層122之層端部122a與第二黏合層121之間。光學膜片結構200的其餘接合步驟同於或類似於光學膜片結構100的對應接合步驟，於此不再贅述。The bonding method of the optical film structure 200 in the embodiment shown in FIG. 2 is similar to the bonding method of the aforementioned optical film structure 100, except that the first coating layer of the first optical film 110 in FIG. 5B 112 and the first adhesive layer 111 do not need to be separated. Then, before the step of FIG. 6B, the layer end 122a of the second coating layer 122 of the second optical film 120 and the second adhesive layer 121 are separated by, for example, a tearing method, to expose the second adhesive layer 121 . Then, corresponding to the step of FIG. 6B, the film end 110a of the first optical film material 110 and the second adhesive layer 121 are bonded. Then, corresponding to the step of Figure 7B, the layer end 122a of the second mating layer 122 covers at least a part of the film end 110a, so that the film end 110a is located at the layer end 122a of the second mating coating layer 122 and Between the second adhesive layer 121. The remaining bonding steps of the optical film structure 200 are the same as or similar to the corresponding bonding steps of the optical film structure 100, and will not be repeated here.
