線偏光層311設于間隔發光組件2處，用以將一具有一第一線偏振方向(圖2中沿x軸方向延伸的橫向箭頭)的線偏光通過，並阻隔一具有一第二線偏振方向(圖2中 沿y軸方向延伸的斜向箭頭)的線偏光通過，該第二線偏振方向與該第一線偏振方向相互垂直。 The line polarizing layer 311 is disposed at the interval light-emitting component 2 for polarizing a line having a first linear polarization direction (a horizontal arrow extending in the x-axis direction in FIG. 2), and blocking a second linear polarization Direction (Figure 2 A line of oblique arrows extending in the y-axis direction is polarized, and the second line polarization direction is perpendicular to the first line polarization direction.
四分之一波板312設於線偏光層311與發光組件2之間，將沿該第一線偏振方向偏振的線偏光及沿一第一圓偏振方向(圖2中順時針方向的環狀箭頭)偏振的圓偏光相互轉換，或將沿第二線偏振方向偏振的線偏光及沿一第二圓偏振方向(圖2中逆時針方向的環狀箭頭)偏振的圓偏光相互轉換，該第二圓偏振方向與該第一圓偏振方向相互反向。 The quarter-wave plate 312 is disposed between the linear polarizing layer 311 and the light-emitting component 2, and polarizes the linearly polarized light along the first linear polarization direction and along a first circular polarization direction (clockwise in FIG. 2). The polarized circularly polarized light of the arrow) is mutually converted, or the linearly polarized light polarized in the second linear polarization direction and the circularly polarized light polarized in a second circular polarization direction (the annular arrow in the counterclockwise direction in FIG. 2) are mutually converted. The two circular polarization directions are opposite to the first circular polarization direction.
反射偏光層313設於四分之一波板312及發光組件2之間，用以將一具有該第一圓偏振方向的圓偏光通過，並反射一具有該第二圓偏振方向的圓偏光。 The reflective polarizing layer 313 is disposed between the quarter-wave plate 312 and the light-emitting assembly 2 for passing a circularly polarized light having the first circular polarization direction and reflecting a circularly polarized light having the second circular polarization direction.
蓋板32設於線偏光層311相反於四分之一波板312的另一側，用於提供保護作用。 The cover plate 32 is provided on the other side of the linear polarizing layer 311 opposite to the quarter-wave plate 312 for providing protection.
參閱圖2，根據上述增亮抗反射結構31的構造，假設外界環境的光線L41具有第一線偏振方向及第二線偏振方向，其往發光顯示裝置1照射而通過線偏光層311後，線偏光層311會阻隔第二線偏振方向的部分，使光線轉為第一線偏振方向的線偏光L42。隨後，線偏光L42通過四分之一波板312後，會轉換為第一圓偏振方向的圓偏光L43，該圓偏光L43可通過反射偏光層313，並在發光結構22(主要是下電極層221處)反射形成第二圓偏振方向的圓偏光L5，該圓偏光L5無法直接穿過反射偏光層313，因此會在反射偏光層313、發光結構22之間反射後轉換為第一 圓偏振方向的圓偏光(未圖示)，然後才能依序穿透反射偏光層313、四分之一波板312及線偏光層311而反射於外，但此時的反射光線的強度已大幅縮減，不至於造成嚴重的反光現象，因此具有減緩外界環境光線L41在發光結構22處產生反射的效果。 Referring to FIG. 2, according to the structure of the brightness enhancement anti-reflection structure 31, it is assumed that the light L41 of the external environment has a first linear polarization direction and a second linear polarization direction, and after the light-emitting display device 1 is irradiated through the linear polarization layer 311, the line The polarizing layer 311 blocks the portion of the second linear polarization direction to convert the light into the linear polarized light L42 of the first linear polarization direction. Then, after the linearly polarized light L42 passes through the quarter-wave plate 312, it is converted into circularly polarized light L43 of the first circular polarization direction, and the circularly polarized light L43 can pass through the reflective polarizing layer 313 and in the light-emitting structure 22 (mainly the lower electrode layer) 221) reflecting the circularly polarized light L5 forming the second circular polarization direction, the circularly polarized light L5 cannot directly pass through the reflective polarizing layer 313, and thus is converted into the first after being reflected between the reflective polarizing layer 313 and the light emitting structure 22. The circularly polarized light in the circular polarization direction (not shown) can then penetrate the reflective polarizing layer 313, the quarter-wave plate 312, and the linear polarizing layer 311 in order to be reflected outside, but the intensity of the reflected light at this time has been greatly increased. The reduction does not cause a serious reflection phenomenon, and therefore has the effect of slowing the reflection of the ambient light L41 at the light-emitting structure 22.
而另一方面，由發光結構22產生的影像光線L61往反射偏光層313照射後，其第一圓偏振方向的圓偏光L62部分可穿過反射偏光層313，且能依序穿過四分之一波板312、線偏光層311，形成第一線偏振方向的線偏光L63而照射於外；而受反射偏光層313反射的第二圓偏振方向的圓偏光L64則會在發光結構22處反射而形成第一圓偏振方向的圓偏光L71，隨後能依序穿過四分之一波板312、線偏光層311，形成第一線偏振方向的線偏光L72而照射於外。因此，發光結構22產生的影像光線L61的絕大部分最終都能穿過增亮抗反射結構31(即線偏光層311、四分之一波板312及反射偏光層313)而穿透於外，所以此種增亮抗反射結構31能大幅增進發光結構22的影像光線使用效率。 On the other hand, after the image light L61 generated by the light-emitting structure 22 is irradiated to the reflective polarizing layer 313, the portion of the circularly polarized light L62 of the first circular polarization direction can pass through the reflective polarizing layer 313, and can pass through the quarter in sequence. The wave plate 312 and the linear polarizing layer 311 form the linearly polarized light L63 of the first linear polarization direction and are irradiated to the outside; and the circular polarized light L64 of the second circular polarization direction reflected by the reflective polarizing layer 313 is reflected by the light emitting structure 22 The circularly polarized light L71 forming the first circular polarization direction is then sequentially passed through the quarter-wave plate 312 and the linearly polarizing layer 311 to form the linearly polarized light L72 of the first linear polarization direction and irradiated to the outside. Therefore, most of the image light L61 generated by the light-emitting structure 22 can finally penetrate through the brightening anti-reflection structure 31 (ie, the linear polarizing layer 311, the quarter-wave plate 312, and the reflective polarizing layer 313). Therefore, the brightening anti-reflection structure 31 can greatly improve the image light use efficiency of the light-emitting structure 22.
本實施例中，線偏光層311可使用高分子碘系聚合物等材質製成的偏光板或使用二色性染料(dichroic dye)搭配液晶分子製作的吸收式偏光層。 In the present embodiment, the linear polarizing layer 311 may be a polarizing plate made of a material such as a polymer iodine polymer or an absorbing polarizing layer made of a liquid crystal molecule using a dichroic dye.
高分子碘系聚合物製成的偏光板是由拉伸方式製作的薄膜材料，例如可由聚乙烯醇(polyvinyl alcohol，簡稱為PVC)薄膜於含碘溶液中拉伸形成，並可進一步施以表面硬化處理(hard coating)以增加其強度。若發光顯示裝置1 的線偏光層311使用此種經表面硬化處理的高分子碘系聚合物偏光板，則其表面可不須設置蓋板32(如圖3)，也就是說在此情況下發光顯示裝置1可以不設置蓋板32。但在製造加工時，若四分之一波板312也是板狀材質，則高分子碘系聚合物製成的偏光板與四分之一波板312之間需要藉由黏著層加以黏合。 The polarizing plate made of the polymer iodine polymer is a film material produced by stretching, for example, a polyvinyl alcohol (PVC) film can be formed by stretching in an iodine-containing solution, and the surface can be further applied. Hard coating to increase its strength. If the light emitting display device 1 The linear polarizing layer 311 uses such a surface-hardened polymeric iodine-based polymer polarizing plate, so that the surface of the polarizing layer 311 does not need to be provided with a cover 32 (see FIG. 3), that is, the light-emitting display device 1 may not be used in this case. A cover plate 32 is provided. However, in the manufacturing process, if the quarter-wave plate 312 is also a plate-like material, the polarizing plate made of the polymer iodine-based polymer and the quarter-wave plate 312 need to be bonded by an adhesive layer.
另一方面，不同於薄膜型態的高分子碘系聚合物製成的偏光板，由二色性染料搭配液晶分子製作的吸收式偏光層屬於藉由塗布制程製作的塗布式線偏光層。二色性染料對於偏振光的具備特殊吸收特性，以圓盤狀染料二色性分子為例，其僅允許垂直于分子方向的光分量通過，並吸收平行于分子平面的光分量，因此控制其分子方向即可設定偏光層的光線偏極方向。此外，由於二色性染料分子不具備液晶的特性，因此可將其與向列型液晶分子混合，以主體-客體(guest-host，簡稱為GH)混合模式的材料特性加以應用，其對水準偏振光分量與垂直偏振光分量具有不同的吸收特性，因此可應用於偏光層的製作。於製造過程中，二色性染料與液晶分子可以直接塗布於各式基材之上而形成偏光層，其厚度較高分子碘系聚合物製成的偏光板為薄，且不需要藉由黏著層與基板結合，因此有助於整體結構的薄型化。 On the other hand, unlike the polarizing plate made of the polymer type iodine-based polymer of the film type, the absorbing polarizing layer made of the dichroic dye and the liquid crystal molecules is a coated linear polarizing layer produced by a coating process. The dichroic dye has a special absorption property for polarized light. Taking a disc-shaped dye dichroic molecule as an example, it only allows the light component perpendicular to the molecular direction to pass, and absorbs the light component parallel to the molecular plane, thus controlling it. The molecular direction can set the polarization direction of the polarizing layer. In addition, since the dichroic dye molecules do not have the characteristics of liquid crystals, they can be mixed with nematic liquid crystal molecules and applied in a material-guest-host (GH) mixed mode material property, which is The polarized light component and the vertically polarized light component have different absorption characteristics, and thus can be applied to the fabrication of the polarizing layer. In the manufacturing process, the dichroic dye and the liquid crystal molecules can be directly coated on various substrates to form a polarizing layer, and the polarizing plate made of a relatively high molecular iodine polymer is thin and does not need to be adhered. The layer is bonded to the substrate, thus contributing to the thinning of the overall structure.
四分之一波板312可使用聚醯亞胺(polyimide，簡稱為PI)等高分子膜製成的板狀材料，或可使用反應型液晶分子製成的光學層。與線偏光層311類似，若四分之一 波板312使用高分子膜製成的板狀材料，則其與其他層之間需要藉由黏著層加以黏合。若使用液晶分子製成的四分之一波板312，其本身的厚度薄於高分子膜，且不需藉由黏著層與其他層進行黏合，因此能減少各層之間的厚度。 The quarter-wave plate 312 may be a plate-like material made of a polymer film such as polyimide (PI), or an optical layer made of reactive liquid crystal molecules. Similar to the linear polarizing layer 311, if one quarter The wave plate 312 is made of a plate-like material made of a polymer film, and it is required to be bonded to the other layers by an adhesive layer. If a quarter-wave plate 312 made of liquid crystal molecules is used, its thickness is thinner than that of the polymer film, and it is not necessary to bond the other layers by the adhesive layer, so that the thickness between the layers can be reduced.
另一方面，本實施例的反射偏光層313是由膽固醇液晶分子製成的光學層，其製作方式是藉由液晶分子的自我組裝(self assembly)特性，利用表面配向(alignment)技術，將膽固醇液晶分子塗布形成呈現特定且單一排列方式的塗層，並于該塗層固化成型後，成為一具有晶體結構之光學薄膜。 On the other hand, the reflective polarizing layer 313 of the present embodiment is an optical layer made of cholesteric liquid crystal molecules, which is produced by self-assembly characteristics of liquid crystal molecules, using surface alignment technology to treat cholesterol. The liquid crystal molecules are coated to form a coating exhibiting a specific and single arrangement, and after the coating is cured and formed, it becomes an optical film having a crystal structure.
要特別說明的是，於前述說明內容中，該第一線偏振方向、第二線偏振方向、第一圓偏振方向、第二圓偏振方向與空間坐標軸x、y、z之間的對應關係僅用於本實施例的示例說明，但不應以該內容限制本發明的實施範圍，例如第一線偏振方向、第二線偏振方向也可以分別對應於y軸方向、x軸方向，且第一圓偏振方向、第二圓偏振方向也可以分別是逆時針方向、順時針方向，此為本領域具有通常知識者可依據前述說明加以調整的技術內容。 It should be particularly noted that, in the foregoing description, the correspondence between the first linear polarization direction, the second linear polarization direction, the first circular polarization direction, the second circular polarization direction, and the spatial coordinate axes x, y, and z It is only used for the description of the embodiment, but the scope of the present invention should not be limited by this content. For example, the first linear polarization direction and the second linear polarization direction may also correspond to the y-axis direction and the x-axis direction, respectively. The circular polarization direction and the second circular polarization direction may also be counterclockwise and clockwise, respectively, which is a technical content that can be adjusted according to the above description by those skilled in the art.
參照圖4、圖5、圖6，為本發明發光顯示裝置1的第二實施例。於第一實施例中，發光顯示裝置1的技術重點在於發光組件2配合具有增亮抗反射結構31的封裝組件3，因此其技術特徵在於增亮抗反射結構31的光學特性。而在本實施例中，發光顯示裝置1的封裝組件3還包括 一觸控感測結構33，因此本實施例的發光顯示裝置1還多了觸控感應的功能。 4, 5, and 6, a second embodiment of the light-emitting display device 1 of the present invention is shown. In the first embodiment, the technical focus of the light-emitting display device 1 is that the light-emitting assembly 2 is fitted with the package assembly 3 having the brightness-increasing anti-reflection structure 31, and thus is technically characterized in that the optical characteristics of the anti-reflection structure 31 are brightened.

於上述說明內容中，本實施例的發光顯示裝置1是以設有蓋板32的實施態樣進行說明。但在發光顯示裝置1的線偏光層311採用經表面處理(硬化處理)的硬質板材(例如前述的高分子碘系聚合物製成的偏光板)的狀況下，發光顯示裝置1也可以不設置蓋板32，也就是說發光顯示裝置1是以線偏光層311作為顯示螢幕的表面。 In the above description, the light-emitting display device 1 of the present embodiment will be described with an embodiment in which the cover 32 is provided. However, in the case where the linear polarizing layer 311 of the light-emitting display device 1 is a surface-treated (hardened) hard plate material (for example, a polarizing plate made of the above-described polymer iodine-based polymer), the light-emitting display device 1 may not be provided. The cover 32, that is, the light-emitting display device 1 is a surface on which the linear polarizing layer 311 is used as a display screen.
參照圖7，為本發明發光顯示裝置1的第二實施例的變化實施態樣。由於本實施態樣不設置蓋板32，第一觸控電極層331調整為設於線偏光層311與四分之一波板312之間、設於四分之一波板312與反射偏光層313之間或 設於反射偏光層313與發光組件2之間(如圖7)，也就是說此時第一觸控電極層331不適宜設於線偏光層311的表面(相反於四分之一波板312的另一側)。 Referring to Fig. 7, a variation of the second embodiment of the light-emitting display device 1 of the present invention is shown. Since the cover layer 32 is not provided in the embodiment, the first touch electrode layer 331 is disposed between the linear polarizing layer 311 and the quarter-wave plate 312, and is disposed on the quarter-wave plate 312 and the reflective polarizing layer. Between 313 or The first touch electrode layer 331 is not disposed on the surface of the linear polarizing layer 311 (opposite to the quarter wave plate 312). The other side).
參閱圖8，為本發明發光顯示裝置1的第三實施例。于本實施例中，發光顯示裝置1設有一增亮抗反射結構31、一蓋板32及一觸控感測結構33，與前述第二實施例相比，本實施例的觸控感測結構33也屬於單層觸控電極結構，但還進一步包括一基板335，該基板335用於供第一觸控電極層331設置其上，且第一觸控電極層331可採用與第二實施例類似的電極形狀配置。 Referring to Figure 8, a third embodiment of the light-emitting display device 1 of the present invention is shown. In the present embodiment, the light-emitting display device 1 is provided with a brightness-increasing anti-reflection structure 31, a cover 32, and a touch-sensing structure 33. Compared with the foregoing second embodiment, the touch-sensing structure of the embodiment 33 is also a single-layer touch electrode structure, but further includes a substrate 335 for the first touch electrode layer 331 disposed thereon, and the first touch electrode layer 331 can be used with the second embodiment.

在本實施例中，觸控感測結構33可設于蓋板32與線偏光層311之間(如圖8)、設於線偏光層311與四分之一波板312之間、設於四分之一波板312與反射偏光層313之間或設於反射偏光層313與發光組件2之間(也就是設於反射偏光層313之下)。 In this embodiment, the touch sensing structure 33 can be disposed between the cover plate 32 and the linear polarizing layer 311 (as shown in FIG. 8 ), between the linear polarizing layer 311 and the quarter wave plate 312 , and The quarter wave plate 312 is disposed between the reflective polarizing layer 313 or between the reflective polarizing layer 313 and the light emitting assembly 2 (that is, disposed under the reflective polarizing layer 313).
參閱圖9，為本發明發光顯示裝置1的第三實施例的變化實施態樣。本實施態樣可以不設置蓋板32，也就是說發光顯示裝置1的封裝組件3只包括增亮抗反射結構31及觸控感測結構33。此狀態下，觸控感測結構33可設於線偏光層311與四分之一波板312之間、設於四分之一波板312與反射偏光層313之間或設於反射偏光層313與發光組件2之間。此外，由於本實施例的觸控感測結構33具有基板335，所以觸控感測結構33還可以設於線偏光層311 相反於四分之一波板312的另一側，也就是位於線偏光層311(顯示螢幕)的表面。 Referring to Fig. 9, a variation of the third embodiment of the light-emitting display device 1 of the present invention is shown. In this embodiment, the cover plate 32 is not provided, that is, the package assembly 3 of the light-emitting display device 1 includes only the brightness-increasing anti-reflection structure 31 and the touch-sensing structure 33. In this state, the touch sensing structure 33 can be disposed between the linear polarizing layer 311 and the quarter wave plate 312, between the quarter wave plate 312 and the reflective polarizing layer 313, or on the reflective polarizing layer. 313 is between the light emitting component 2. In addition, since the touch sensing structure 33 of the embodiment has the substrate 335 , the touch sensing structure 33 can also be disposed on the linear polarizing layer 311 . The other side of the quarter-wave plate 312 is opposite to the surface of the line polarizing layer 311 (display screen).
參閱圖10、圖11，為本發明發光顯示裝置1的第四實施例。于本實施例中，發光顯示裝置1設有一增亮抗反射結構31、一蓋板32及一觸控感測結構33，但觸控感測結構33的觸控感測機制與前述第三實施例不同，屬於雙層式觸控電極結構。因此，相較於第三實施例，本實施例的觸控感測結構33還具有一第二觸控電極層332，也就是說觸控感測結構33具有一第一觸控電極層331及一第二觸控電極層332，該第一觸控電極層331及一第二觸控電極層332由透明導電材質製成，所述第一觸控電極層331具有多個沿一第一方向(圖11中的縱向方向)排列的第一電極列333，所述第二觸控電極層332具有多個沿一第二方向(圖11中的橫向方向)排列的第二電極列334，該第二方向與該第一方相互交錯，所以使用者可透過此種觸控感測結構33於顯示螢幕上進行觸控點的偵測。 Referring to Figures 10 and 11, a fourth embodiment of the light-emitting display device 1 of the present invention is shown. In the embodiment, the light-emitting display device 1 is provided with a brightness-increasing anti-reflection structure 31, a cover plate 32 and a touch-sensing structure 33, but the touch sensing mechanism of the touch-sensing structure 33 and the third implementation described above In different cases, it belongs to a two-layer touch electrode structure. Therefore, the touch sensing structure 33 of the present embodiment further has a second touch electrode layer 332, that is, the touch sensing structure 33 has a first touch electrode layer 331 and The first touch electrode layer 331 and the second touch electrode layer 332 are made of a transparent conductive material, and the first touch electrode layer 331 has a plurality of first directions. a first electrode array 333 arranged in a longitudinal direction (in FIG. 11), the second touch electrode layer 332 having a plurality of second electrode columns 334 arranged in a second direction (lateral direction in FIG. 11), The second direction is interlaced with the first party, so that the user can perform touch point detection on the display screen through the touch sensing structure 33.
在本實施例中，第一觸控電極層331與第二觸控電極層332間隔地設於線偏光層311、四分之一波板312、反射偏光層313的三者至少其中之一的兩相反側，也就是說第一觸控電極層331與第二觸控電極層332是彼此不直接接觸地設置於增亮抗反射結構31的各層之間。 In this embodiment, the first touch electrode layer 331 and the second touch electrode layer 332 are disposed at least one of the three of the linear polarizing layer 311, the quarter wave plate 312, and the reflective polarizing layer 313. The two opposite sides, that is, the first touch electrode layer 331 and the second touch electrode layer 332 are disposed between the layers of the brightening anti-reflective structure 31 without being in direct contact with each other.
例如，於圖10中第一觸控電極層331與第二觸控電極層332是間隔地設於線偏光層311的兩相反側，此 種觸控感測結構33鄰近顯示螢幕(蓋板32)的表面。 For example, in FIG. 10, the first touch electrode layer 331 and the second touch electrode layer 332 are spaced apart from each other on opposite sides of the line polarizing layer 311. The touch sensing structure 33 is adjacent to the surface of the display screen (cover 32).
此外，第一觸控電極層331與第二觸控電極層332也可以間隔地設置於反射偏光層313的兩相反測。 In addition, the first touch electrode layer 331 and the second touch electrode layer 332 may also be disposed at opposite intervals of the reflective polarizing layer 313.
或者，第一觸控電極層331與第二觸控電極層332還可以間隔地設於線偏光層311、四分之一波板312、反射偏光層313的兩相反側，也就是說此時第一觸控電極層331是設于蓋板32與線偏光層311之間，第二觸控電極層332則是設於反射偏光層313之下。 Alternatively, the first touch electrode layer 331 and the second touch electrode layer 332 may be spaced apart from each other on opposite sides of the linear polarizing layer 311, the quarter wave plate 312, and the reflective polarizing layer 313, that is, at this time. The first touch electrode layer 331 is disposed between the cover 32 and the linear polarizing layer 311 , and the second touch electrode layer 332 is disposed under the reflective polarizing layer 313 .
要注意的是，上述第一觸控電極層331、第二觸控電極層332的設置方式只是本實施例的示例說明，本實施例的第一觸控電極層331、第二觸控電極層332可彈性地分別設置于蓋板32、線偏光層311、四分之一波板312、反射偏光層313的各層之間，且於相互配合後提供觸控感應功能，因此其實施態樣不以特定型態為限。 It is to be noted that the first touch electrode layer 331 and the second touch electrode layer 332 are disposed in the embodiment, and the first touch electrode layer 331 and the second touch electrode layer are provided in this embodiment. The 332 is elastically disposed between the layers of the cover 32, the linear polarizing layer 311, the quarter-wave plate 312, and the reflective polarizing layer 313, and provides a touch sensing function after being matched with each other, so that the implementation manner is not Limited to a specific type.
參閱圖12，為本發明發光顯示裝置1的第四實施例的變化實施態樣。本實施態樣可以不設置蓋板32，也就是說封裝組件3只包括增亮抗反射結構31及觸控感測結構33。在此實施態樣中，第一觸控電極層331與第二觸控電極層332是間隔地設於四分之一波板312、反射偏光層313的兩者至少其中之一的兩相反側，也就是說第一觸控電極層331與第二觸控電極層332可以分別設置於線偏光層311與四分之一波板312之間、四分之一波板312與反射偏光層313之間或反射偏光層313之下，但不能設置於線偏光層311的表面。 Referring to Fig. 12, a variation of the fourth embodiment of the light-emitting display device 1 of the present invention is shown.
