Description
本發明涉及一種偏光片結構，尤其涉及一種偏光片結構、顯示面板及其製造方法。The invention relates to a polarizer structure, in particular to a polarizer structure, a display panel and a manufacturing method thereof.
由於高科技電子資訊業的蓬勃發展，消費性電子産品已成爲人們日常生活中的必需品，且許多消費性電子産品已朝向輕薄短小的趨勢邁進，特別是結合顯示與輸入兩種技術的觸控式顯示裝置，其同時具有顯示與觸控輸入的功能，而能大幅度提升各類消費性電子産品的實用性能。Due to the rapid development of high-tech electronic information industry, consumer electronic products have become a necessity in people's daily life, and many consumer electronic products have moved toward a trend of lightness and thinness, especially touch-sensitive technology combining display and input technologies. The display device has the functions of display and touch input at the same time, and can greatly improve the practical performance of various consumer electronic products.
顯示面板的研發，設計及生産中，良率爲影響觸控顯示面板能否量産的一種重要因素，作爲模組後段，良率顯得尤爲重要。在顯示面板中，偏光片因其透明度和偏光性爲顯示面板必須的零件。In the development, design and production of display panels, the yield is an important factor affecting the mass production of touch display panels. As the latter part of the module, the yield is particularly important. In the display panel, the polarizer is a necessary part of the display panel due to its transparency and polarization.
在模組後段中，偏光片貼附在觸摸面板上，使自然光變成偏振光，偏振片還要與覆蓋玻璃（cover lens）或觸控傳感器貼附在一起，而貼附的良率對於整個工藝非常重要，模組後段造成的貼附不良意味著包括前段的設計及蒸鍍、封裝等整個工藝的失敗。In the rear part of the module, the polarizer is attached to the touch panel to make the natural light become polarized light, and the polarizer is attached to the cover lens or the touch sensor, and the yield of the attached is for the entire process. It is very important that the poor adhesion caused by the rear section of the module means the design of the front section and the failure of the entire process such as evaporation and packaging.

下面結合附圖和實施例對本發明作進一步的詳細說明。可以理解的是，此處所描述的具體實施例僅僅用於解釋本發明，而非對本發明的限定。另外還需要說明的是，爲了便於描述，附圖中僅示出了與本發明相關的部分而非全部結構。The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should also be noted that, for ease of description, only some, but not all, of the structures related to the present invention are shown in the drawings.
圖1爲本具體實施方式中提供的偏光片結構示意圖。該偏光片包括:離型膜1，設置在離型膜1上的偏光片主體2，設置在偏光片主體2上的黏結層3，設置在所述黏結層3上的表面保護膜4，所述黏結層3的材料可以爲有機矽橡膠、丙烯酸型樹脂及不飽和聚酯、聚氨酯、環氧樹脂等中的任一種或幾種。在優選的方式中，所述黏結層3由丙烯酸型樹脂材料組成。當偏光片需要與覆蓋玻璃或觸控顯示器結合時，將偏光片最上面一層的表面保護膜4撕去即可通過黏結層3實現與覆蓋玻璃或觸控顯示器的結合。FIG. 1 is a schematic structural view of a polarizer provided in the specific embodiment. The polarizer comprises: a release film 1, a polarizer main body 2 disposed on the release film 1, a bonding layer 3 disposed on the polarizer main body 2, and a surface protective film 4 disposed on the adhesive layer 3. The material of the adhesive layer 3 may be any one or more of an organic silicone rubber, an acrylic resin, and an unsaturated polyester, a polyurethane, an epoxy resin, or the like. In a preferred form, the adhesive layer 3 is composed of an acrylic resin material. When the polarizer needs to be combined with the cover glass or the touch display, the surface protective film 4 of the uppermost layer of the polarizer can be removed to bond with the cover glass or the touch display through the adhesive layer 3.
在傳統的工藝中偏光片不包括黏結層，在需要與覆蓋玻璃或觸控顯示器結合時，需要採用在偏光片上貼附OCA膠的方法。OCA膠包括自上而下的輕離型膜、黏結層和重離型膜。當使用OCA膠時需要將OCA膠兩面的輕離型膜和重離型膜撕去，與偏光片黏結在一起，再與覆蓋玻璃或觸控顯示器黏結，這個過程需要兩次撕去離型膜的工序，並且需要對OCA膠進行裁切，工序較多，容易造成良率下降。In the conventional process, the polarizer does not include a bonding layer, and when it is required to be combined with a cover glass or a touch display, a method of attaching an OCA paste to the polarizer is required. OCA glue includes top-down light release film, adhesive layer and heavy release film. When using OCA glue, it is necessary to tear off the light release film and the heavy release film on both sides of the OCA glue, and bond it with the polarizer, and then bond it with the cover glass or the touch display. This process requires tearing off the release film twice. In the process, it is necessary to cut the OCA glue, and there are many processes, which tends to cause a drop in yield.
而本具體實施方式的偏光片自身就包括黏結層，直接實現與覆蓋玻璃或觸控顯示器的結合，減少了工序，提高了良率。The polarizer of the specific embodiment itself includes a bonding layer, which directly realizes the combination with the cover glass or the touch display, reduces the process, and improves the yield.
本具體實施方式中的偏光片主體的結構示意圖如圖2所示，包括壓敏膠2-1，設置在所述壓敏膠上的光學延遲片2-2，設置在所述光學延遲片上的膠合劑2-3，設置在所述膠合劑上的聚乙烯醇（PVA）層2-4，以及設置在所述聚乙烯醇層上的三醋酸纖維素酯（TAC）層2-5。也可以採用其他結構的偏光片主體實現本具體實施方式的偏光片。The structure of the polarizer main body in this embodiment is as shown in FIG. 2, and includes a pressure sensitive adhesive 2-1, an optical retarder 2-2 disposed on the pressure sensitive adhesive, and disposed on the optical retarder. Glue 2-3, a polyvinyl alcohol (PVA) layer 2-4 disposed on the binder, and a cellulose triacetate (TAC) layer 2-5 disposed on the polyvinyl alcohol layer. The polarizer of the specific embodiment can also be realized by using a polarizer main body of another structure.

如圖3所示，首先在步驟S1中形成離型膜，接著在步驟S2中在所述離型膜上形成偏光片主體，然後在偏光片主體上形成黏結層，如步驟S3示。最後在黏結成上形成表面保護膜，如步驟S4所示。其中所述黏結層的材料可以爲有機矽橡膠、丙烯酸型樹脂及不飽和聚酯、聚氨酯、環氧樹脂等中的任一種或幾種。在優選的方式中，所述黏結層由丙烯酸型樹脂材料組成。As shown in Fig. 3, a release film is first formed in step S1, then a polarizer body is formed on the release film in step S2, and then a bonding layer is formed on the polarizer body, as shown in step S3. Finally, a surface protective film is formed on the bond, as shown in step S4. The material of the adhesive layer may be any one or more of an organic silicone rubber, an acrylic resin, and an unsaturated polyester, a polyurethane, an epoxy resin, and the like. In a preferred form, the bonding layer is composed of an acrylic resin material.
