Description
本發明是有關於一種顯示裝置，特別是指一種具有觸控功能的有機發光二極體觸控顯示裝置。 The present invention relates to a display device, and more particularly to an organic light emitting diode touch display device having a touch function.
參見圖1，現有一種有機發光二極體(以下簡稱OLED)顯示器1主要包括一基板10，一設於基板10上的有機發光模組11以及一覆蓋於有機發光模組11上方的透明蓋板12，例如玻璃或透明壓克力(PET)板。且基板10與透明蓋板12的周緣之間會以一封膠層13黏合，以將有機發光模組11封閉於兩者之間，使不致受潮氧化。且由於OLED顯示器1為自發光之顯示模式，其在室內或低環境光之條件下，具有高對比、高色彩飽和度之顯示特性，但其如果處於高照度之環境光源下，如接受室外的太陽光照射時，因OLED本身的亮度遠低於外界環境光，則由OLED顯示器1表面所反射的外界光將會讓使用者看不清楚OLED顯示器1所顯示的畫面。 Referring to FIG. 1 , a conventional organic light emitting diode ( OLED ) display 1 mainly includes a substrate 10 , an organic light emitting module 11 disposed on the substrate 10 , and a transparent cover over the organic light emitting module 11 . 12, such as glass or transparent acrylic (PET) sheets. An adhesive layer 13 is adhered between the substrate 10 and the periphery of the transparent cover 12 to enclose the organic light-emitting module 11 between the two so as not to be oxidized by moisture. And because the OLED display 1 is a self-illuminating display mode, it has high contrast and high color saturation display characteristics under indoor or low ambient light conditions, but if it is under a high illumination ambient light source, such as accepting outdoor When the sunlight is irradiated, since the brightness of the OLED itself is much lower than the ambient light, the external light reflected by the surface of the OLED display 1 will make the user not see the picture displayed by the OLED display 1.
因此，為解決上述問題，傳統的做法是在OLED顯示器1的透明蓋板12上再設置一由四分之一波板與一偏光板所構成的光學膜片組(圖未示)，使吸收來自外界的入射 光。其中偏光板是由TAC(三醋酸纖維素)膜為保護層、PVA(聚乙烯醇)為偏光基體及TAC膜為另一保護層共三層厚度從數十微米到數百微米的薄膜材料組成。 Therefore, in order to solve the above problem, a conventional method is to further provide an optical film group (not shown) composed of a quarter-wave plate and a polarizing plate on the transparent cover 12 of the OLED display 1 to absorb Incident from the outside world Light. The polarizing plate is composed of a TAC (triacetate cellulose) film as a protective layer, PVA (polyvinyl alcohol) as a polarizing substrate and a TAC film as another protective layer, and a total of three layers of film materials having a thickness ranging from several tens of micrometers to several hundreds of micrometers. .
此外，若要讓OLED顯示器1同時具備觸控功能，則可以在OLED顯示器1的光學膜片組上再設置一現成的觸控感測模組(圖未示)，但如此一來，具備觸控功能的OLED顯示器的積體和重量將大大地增加，而難以應用在以輕薄為要求的電子產品上。 In addition, if the OLED display 1 is to have a touch function at the same time, an off-the-shelf touch sensing module (not shown) can be disposed on the optical film set of the OLED display 1, but in this case, the touch is provided. The integrated body and weight of the OLED display with control functions will be greatly increased, and it is difficult to apply to electronic products that are required to be thin and light.
因此，本發明的目的在於提供一種能降低產品整體厚度及重量的有機發光二極體觸控顯示裝置。 Therefore, an object of the present invention is to provide an organic light emitting diode touch display device capable of reducing the overall thickness and weight of a product.

再者，上述的四分之一波板31、51、65、84利用液晶分子具有自我組裝之特性(self-assembly)，例如反應型液晶，以及相對成熟之表面配向技術，實現了大面積液晶的規則性排列，在膜體固化成形後，成為一具有晶體結構之薄膜厚度。由於四分之一波板31、51、65、84厚度只有數微米，相較於傳統的四分之一波板厚度減少許多，故能有效降低封裝組件30、50、70、90的整體厚度。且上述某些並非做為承載基材的偏光板32、52、91，也可以利用上述的液晶分子自我組裝特性及表面配向技術，由例如膽固醇液晶材料製成，而進一步減少偏光板32、52、91的厚度至只有數微米，且由於不需使用TAC保護膜，相較於傳統的偏光板厚度減少許多，甚至透過特定的塗佈技術，可 將液晶偏光板32、52的厚度減少至約1微米，而更進一步降低封裝組件30、50、90的整體厚度。而且由於不使用傳統的四分之一波板，除了不需擔心板材缺貨、備料等問題，且可由業者自行於封裝組件30、50或有機發光組件60、80上塗佈液晶材料製作四分之一波板31、51或65、84，以縮短製程時間，並方便因應不同產品規格需求，彈性調整四分之一波板31、51或65、84的厚度及塗佈位置等，而且可以節省部分向外購置四分之一波板的費用，使產品的製造成本降低。 Furthermore, the above-mentioned quarter-wave plates 31, 51, 65, 84 utilize liquid crystal molecules with self-assembly, such as reactive liquid crystals, and relatively mature surface alignment technology to realize large-area liquid crystals. The regular arrangement becomes a film thickness having a crystal structure after the film is solidified and formed. Since the thickness of the quarter-wave plates 31, 51, 65, 84 is only a few micrometers, the thickness of the package components 30, 50, 70, 90 can be effectively reduced as compared with the conventional one-quarter wave plate. . Further, some of the polarizing plates 32, 52, and 91 which are not used as the carrier substrate may be made of, for example, a cholesteric liquid crystal material by using the above-described liquid crystal molecule self-assembly characteristics and surface alignment technology, thereby further reducing the polarizing plates 32 and 52. The thickness of 91 is only a few micrometers, and since the TAC protective film is not required, the thickness of the polarizing plate is much reduced compared to the conventional polarizing plate, even through a specific coating technique. The thickness of the liquid crystal polarizing plates 32, 52 is reduced to about 1 micron, and the overall thickness of the package components 30, 50, 90 is further reduced. Moreover, since the conventional quarter-wave plate is not used, there is no need to worry about the shortage of the plate, the preparation of the material, and the like, and the manufacturer can apply the liquid crystal material on the package component 30, 50 or the organic light-emitting component 60, 80 to make a four-point. One of the wave plates 31, 51 or 65, 84, in order to shorten the process time, and to flexibly adjust the thickness and coating position of the quarter wave plates 31, 51 or 65, 84 in response to different product specifications, and Saving part of the cost of purchasing a quarter-wave plate, which reduces the manufacturing cost of the product.
此外，上述該等實施例還可包含一邊框裝飾油墨層(decoration layer)，其可設於玻璃36、54、74、93的下表面，設於四分之一波板31、51、65、84的上表面或下表面，或設於有機發光元件40、60、80的基板41、61、81的上表面等位置。 In addition, the above embodiments may further include a frame decoration ink layer, which may be disposed on the lower surface of the glass 36, 54, 74, 93, and disposed on the quarter wave plates 31, 51, 65, The upper surface or the lower surface of 84 is provided at the upper surface of the substrates 41, 61, 81 of the organic light-emitting elements 40, 60, 80, and the like.
綜上所述，上述實施例的有機發光二極體觸控顯示裝置藉由將由液晶材料形成的四分之一波板、偏光板及觸控電極結構整合在封裝元件上，或者藉由將由液晶材料形成的四分之一波板及(或)一部分觸控電極結構整合在有機發光元件上，且偏光板及另一部分觸控電極結構整合在封裝元件上，以取代傳統有機發光二極體顯示器的封裝上蓋，不但使有機發光二極體觸控顯示裝置同時具備顯示、光學抗反射及觸控功能，並至少省去傳統有機發光組件的玻璃蓋板及觸控感測模組的玻璃蓋板、兩層黏合玻璃蓋板的OCA(Optical clear Adhesive)光學膠，而有效減少有機 發光二極體觸控顯示裝置的厚度及重量。此外，本發明使用液晶材料製作四分之一波板，可將四分之一波板的厚度由傳統的數百微米降低到數微米，能更進一步減少有機發光二極體觸控顯示裝置的整體厚度，確實達成本發明的功效和目的。 In summary, the organic light emitting diode touch display device of the above embodiment integrates the quarter wave plate, the polarizing plate and the touch electrode structure formed of the liquid crystal material on the package component, or by using the liquid crystal The quarter-wave plate and/or a part of the touch electrode structure formed by the material are integrated on the organic light-emitting element, and the polarizing plate and another part of the touch electrode structure are integrated on the package component to replace the traditional organic light-emitting diode display. The cover of the package not only enables the display, optical anti-reflection and touch functions of the organic light-emitting diode touch display device, but also eliminates at least the glass cover of the conventional organic light-emitting component and the glass cover of the touch-sensing module. Two layers of OCA (Optical Clear Adhesive) optical adhesive bonded to the glass cover, effectively reducing organic The thickness and weight of the light-emitting diode touch display device. In addition, the present invention uses a liquid crystal material to fabricate a quarter-wave plate, which can reduce the thickness of the quarter-wave plate from a conventional hundreds of micrometers to several micrometers, thereby further reducing the organic light-emitting diode touch display device. The overall thickness does achieve the efficacy and purpose of the present invention.
