Description
本發明為一種之觸控面板,提供一種可整合於顯示器模組使具有觸控功能之觸控面板及其製造方法。 The invention provides a touch panel, and provides a touch panel that can be integrated into a display module to have a touch function and a manufacturing method thereof.
在現今各式消費性電子產品的市場中,個人數位助理(PDA)、行動電話(mobile Phone)、筆記型電腦(notebook)及平板電腦(tablet PC)等可攜式電子產品皆已廣泛的使用觸控式面板(touch panel)作為其資料溝通的界面工具。此外,由於目前電子產品的設計皆以輕、薄、短、小為方向,因此在產品上無足夠空間容納如鍵盤、滑鼠等傳統輸入裝置,尤其在講求人性化設計的平板電腦需求的帶動下,觸控式面板已經一躍成為關鍵的零組件之一。而且觸控式面板除了符合可作多層次選單設計要求外,亦能同時擁有鍵盤、滑鼠等的功能及手寫輸入等人性化的操作方式,尤其將輸入與輸出整合在同一介面(螢幕)的特質,更是其他傳統輸入裝置所不及之處。 In today's market for consumer electronics products, portable electronic products such as personal digital assistants (PDAs), mobile phones, notebooks, and tablet PCs have been widely used. A touch panel is used as an interface tool for data communication. In addition, since the design of electronic products is currently in the direction of light, thin, short and small, there is not enough space on the product to accommodate traditional input devices such as keyboards and mice, especially in the demand for tablet PCs that are designed with humanity in mind. Next, touch panels have become one of the key components. In addition to the multi-level menu design requirements, the touch panel can also have the functions of keyboard, mouse and other humanized operation modes, especially the integration of input and output in the same interface (screen). The traits are beyond the reach of other traditional input devices.
目前具有觸控功能的平面顯示器的製法及結構種類眾多。早期觸控面板係獨立生產,待完成後才與尺寸配合的液晶面板結合,因此如要製造具有觸控功能的平面顯示器;其中一種最直接的作法,即將一觸控面板透過結合手段,如塗佈一層黏貼層,將觸控面板貼附於該液晶顯示面板的前面板上端面,而該液晶顯示面板包括自上而下層疊設置之一上偏光片、一上玻璃板、一液晶層、一下玻璃板及一下偏光片。 該觸控面板藉由該黏貼層貼附於該液晶顯示面板之上偏光片之上側。 Currently, flat panel displays with touch functions have a wide variety of methods and structures. The early touch panels were independently produced, and only after they were completed, they were combined with the size-matched LCD panels. Therefore, if a flat panel display with touch function is to be manufactured, one of the most direct methods is to pass a touch panel through a bonding means, such as coating. a layer of adhesive layer is attached to the front surface of the front panel of the liquid crystal display panel, and the liquid crystal display panel comprises a top polarizer, an upper glass plate, a liquid crystal layer, and a lower layer. Glass plate and polarizer. The touch panel is attached to the upper side of the polarizer on the liquid crystal display panel by the adhesive layer.
然而,前述觸控式平面顯示器在發展過程中,會產生可視度過低的技術性問題,也就是說,由於觸控面板成為多層構造,光線通過液晶顯示面板,再通過多層觸控面板之構造,容易造成光線穿透率或視角補償性等光學特性不足,而限制了觸控式平面顯示器的可視度;並且在觸控面板的製造過程中,因為多層結構的貼附良率不易控制,導致增加生產成本。 However, in the development process of the above-mentioned touch-type flat panel display, there is a technical problem that the visibility is too low, that is, since the touch panel becomes a multi-layer structure, light passes through the liquid crystal display panel, and then through the structure of the multi-layer touch panel. It is easy to cause insufficient optical characteristics such as light transmittance or viewing angle compensation, and limits the visibility of the touch panel display; and in the manufacturing process of the touch panel, the adhesion yield of the multilayer structure is difficult to control, resulting in Increase production costs.
