Description

偏極化之電容式觸控面板及應用彼之顯示器 Polarized capacitive touch panel and display of the same

本創作隸屬一種觸控面板之技術領域，具體而言係指一種可視度高的偏極化之電容式觸控面板，以減低環境光線對顯示器顯影的影響，同時可延長產品的使用壽命。 This creation belongs to the technical field of a touch panel, specifically a polarized capacitive touch panel with high visibility to reduce the influence of ambient light on the development of the display, and at the same time prolong the service life of the product.

按，觸控面板【Touch Panel】是一種配置於顯示器表面，供使用者藉由手指或觸控筆觸壓觸控面板上的相應位置，完成資料傳輸或選擇所需的訊息，其被廣泛的應用於各種電子產品，作為取代滑鼠、鍵盤等操作用之人機介面，包含筆記型電腦、平板電腦、數位相機、數位相框、智慧型手機、導航裝置等，提供人們更為便捷、且人性化的操作模式，由於這些設備具有極佳的可攜性，因此其在戶外陽光或室內燈光下使用的機會越來越多。 The touch panel [Touch Panel] is a type of display on the surface of the display, which allows the user to touch the corresponding position on the touch panel by a finger or a stylus to complete the data transmission or select the desired information, which is widely used. As a human-machine interface for replacing electronic devices, such as a mouse, a keyboard, etc., including a notebook computer, a tablet computer, a digital camera, a digital photo frame, a smart phone, a navigation device, etc., providing people with convenience and humanity. The mode of operation, due to the excellent portability of these devices, is increasingly used in outdoor sunlight or indoor lighting.

傳統觸控面板早期係為獨立生產，待完成後才與尺寸相符的平面顯示器結合，因此欲使一平面顯示器具備觸控功能，需進一步裝設一對應尺寸之觸控面板，其結合方式可採用黏貼，令觸控面板貼附於該平面顯示器的表面。由於平面顯示器，如液晶顯示器，易受限於環境光線強度的強弱，而有可視度品質優劣的差異，當該觸控面板直接設於該平面顯示器上，將產生嚴重反射，其整體反射率可高達25%，導致於強烈的 外在環境光照下，使用者無法自該觸控式平面顯示器的出光面清楚觀看影像。 In the early days, the conventional touch panel was independently produced. It was only combined with a flat-panel display that conformed to the size. Therefore, in order to make a flat-panel display have a touch function, a touch panel of a corresponding size needs to be further installed. Adhesive, the touch panel is attached to the surface of the flat display. Since a flat panel display, such as a liquid crystal display, is easily limited by the intensity of ambient light, and there is a difference in the quality of the visibility, when the touch panel is directly disposed on the flat display, severe reflection will occur, and the overall reflectance can be Up to 25%, resulting in strong Under external ambient light, the user cannot clearly view the image from the light-emitting surface of the touch-sensitive flat panel display.

為了改善於強光下影像可視度不佳之問題，一般觸控式平面顯示器會藉由光偏振原理，於其觸控面板表面加設一偏光板，如此可利用外界光源的不同偏振方向特性，令偏光板吸收大部份外界光源降低反射，此法雖可改善光反射，但於實際應用下，仍有耐磨耗與使用壽命……等等問題，其因一般偏光板表面硬度約只有2~3H，於長期使用下易造成表面磨損或刮傷狀況產生。 In order to improve the image visibility under strong light, the general touch-type flat panel display has a polarizing plate on the surface of the touch panel by the principle of light polarization, so that different polarization directions of the external light source can be utilized. The polarizing plate absorbs most of the external light sources to reduce the reflection. Although this method can improve the light reflection, in practice, there is still wear resistance and service life, etc., because the surface hardness of the general polarizing plate is only about 2~ 3H, it is easy to cause surface abrasion or scratching under long-term use.

換言之，現有觸控面板因反射及折射問題，而造成顯示器的可視性降低，再加上其表面存在有易磨損或刮傷的問題，因此如何解決這些困擾，是業界相當重要的課題。 In other words, the existing touch panel has a problem of reflection and refraction, which causes the visibility of the display to be lowered, and the surface thereof has problems of being easily worn or scratched. Therefore, how to solve these problems is an important issue in the industry.

有鑑於此，本發明即在於解決現有具觸控面板之顯示器所面臨的可視性問題，而經由本發明人長期從事相關產業的研發與製作經驗，經不斷努力的改良，終於成功開發一種偏極化之電容式觸控面板及應用彼之顯示器，藉以克服現有因可視度差及易磨損所造成的困擾與不便。 In view of the above, the present invention solves the problem of visibility faced by existing displays with touch panels, and the inventors have long been engaged in the research and development and production experience of related industries, and have been continuously improving the development of a pole. The capacitive touch panel and its display are used to overcome the existing problems and inconvenience caused by poor visibility and wear.

因此，本發明之主要目的係提供一種偏極化之電容式觸控面板及應用彼之顯示器，使其能有效降低外界光線進入的反射率，以提供清楚的顯影畫面，減低環境光線對顯影的影響，進一步提高其可視度。 Therefore, the main object of the present invention is to provide a polarized capacitive touch panel and a display thereof, which can effectively reduce the reflectivity of external light entering, thereby providing a clear developing picture and reducing ambient light for development. Influence, further improve its visibility.

又，本發明之另一主要目的係提供一種偏極化之電容式觸控面板及應用彼之顯示器，其能利用層疊結構的改變 ，有效提高表面的耐磨與耐刮性，減少觸控面板表面的損傷，以有效延長其使用壽命。 Moreover, another main object of the present invention is to provide a polarized capacitive touch panel and a display thereof, which can utilize the change of the laminated structure. It effectively improves the wear and scratch resistance of the surface and reduces the damage of the surface of the touch panel to effectively extend its service life.

And comprising a conductive substrate, a polarizing plate and a protective substrate; wherein a first phase difference plate is adhered to the lower surface of the conductive substrate, and a second phase is adhered between the upper surface of the conductive substrate and the lower surface of the polarizing plate a differential plate, wherein the lower surface of the polarizing plate is adhered to the surface of the second phase difference plate, and the surface of the polarizing plate is adhered to the lower surface of the protective substrate, and the optical axis angles of the polarizing plates are respectively the first The two phase difference plates are divided into an angle difference.

藉此，透過前述技術手段的展現，使得本發明之電容式觸控面板於導電基板上增設一偏光板及至少一相位差板，令其於強光照射下，可將光線反射轉化為螢幕出光面的光線，有效提高螢幕亮度，減低環境光線對顯影的影響，提高其可視度，同時本發明應用改變組成疊構之設計，於偏光板上表面設有一保護基板，且層間使用光學膠黏著，由於此保護基板材質一般為玻璃或壓克力等材料，大幅提高觸控面板的耐磨性與耐刮性，有效解決使用壽命與磨耗問題，進一步延長其使用壽命。 Therefore, through the foregoing technical means, the capacitive touch panel of the present invention adds a polarizing plate and at least one phase difference plate to the conductive substrate, so that the light reflection can be converted into the light output under the illumination of the strong light. The surface light effectively increases the brightness of the screen, reduces the influence of ambient light on the development, and improves the visibility thereof. At the same time, the application of the invention changes the composition of the stack, and a protective substrate is disposed on the surface of the polarizing plate, and the layers are optically bonded. Since the material of the protective substrate is generally glass or acrylic, the wear resistance and scratch resistance of the touch panel are greatly improved, the service life and wear problems are effectively solved, and the service life is further extended.
