Description
本發明係關於一種顯示裝置，且特別關於一種電容式壓感顯示裝置。The invention relates to a display device, and more particularly to a capacitive pressure-sensitive display device.
在現今各式消費性電子產品市場中，個人數位助理(personal digital assistant，PDA)、行動電話(mobile phone)、車用觸控螢幕裝置及筆記型電腦(notebook)等可攜式電子產品皆已廣泛使用觸控面板(touch panel)作為使用者與電子裝置間之資料溝通介面工具。並常見觸控技術的種類繁多，如電阻式、電容式或光學式觸控等，其可借由手指或電磁筆的觸控，判斷其觸控位置，以執行相應的功能。但是觸控技術不僅要能控制及操作產品的功能，對於書寫或繪圖或玩遊戲的應用，更是目前觸控技術發展的主要趨勢。In today's various consumer electronics markets, portable electronic products such as personal digital assistants (PDAs), mobile phones, touch screen devices for automobiles, and notebooks have all been available. The touch panel is widely used as a data communication interface tool between a user and an electronic device. And there are many types of common touch technologies, such as resistive, capacitive, or optical touch, etc., which can determine the touch position to perform corresponding functions by touching with a finger or an electromagnetic pen. However, touch technology must not only be able to control and operate the functions of the product, but also the main trend in the development of touch technology for applications such as writing or drawing or playing games.
為了滿足人們越來越多的人機互動應用要求，傳統觸控式顯示裝置中設有壓感模組，以測試到觸摸的力度。如第1圖所示，第1圖為先前技術之觸控顯示裝置之結構剖視圖，此觸控顯示裝置除了壓感模組10外，更包含一塑膠框體12、一光學膜層14、一薄膜電晶體陣列顯示模組16、一第一透明電極串列層18、一透明基板20、一第二透明電極串列層22與一玻璃基板24。壓感模組10更包含一中置框體26、一基板28與複數壓力感測器30。光學膜層14與薄膜電晶體陣列顯示模組16皆設於塑膠框體12上，但光學膜層14與薄膜電晶體陣列顯示模組16卻彼此相隔，且第一透明電極串列層18、透明基板20、第二透明電極串列層22與玻璃基板24再依序設於薄膜電晶體陣列顯示模組16上。在壓感模組10中，基板28與壓力感測器30亦依序設於中置框體26上，但壓力感測器30亦與塑膠框體12相隔。利用薄膜電晶體陣列顯示模組16與壓力感測器30可以建立壓感電容，當手指按壓玻璃基板24時，薄膜電晶體陣列顯示模組16、第一透明電極串列層18、透明基板20、第二透明電極串列層22與玻璃基板24皆朝光學膜層14產生形變，以改變壓感電容，並據此計算壓力大小。然而，因為壓力感測器30設於中置框體26上，故需限制塑膠框體12之材質，不可為導體，且需將中置框體26之平整度、開孔大小與數量列入考量，此外，組裝公差與機構變形穩定度之問題，將成為影響壓力感測器30之不穩定因素。In order to meet the requirements of more and more human-computer interaction applications, a pressure-sensitive module is provided in a conventional touch display device to test the strength of the touch. As shown in FIG. 1, FIG. 1 is a cross-sectional view of a structure of a prior art touch display device. In addition to the pressure-sensitive module 10, the touch display device further includes a plastic frame 12, an optical film layer 14, a The thin film transistor array display module 16, a first transparent electrode tandem layer 18, a transparent substrate 20, a second transparent electrode tandem layer 22 and a glass substrate 24.

The optical film layer 14 and the thin-film transistor array display module 16 are both disposed on the plastic frame 12, but the optical film layer 14 and the thin-film transistor array display module 16 are separated from each other, and the first transparent electrode series layer 18, The transparent substrate 20, the second transparent electrode serial layer 22, and the glass substrate 24 are sequentially disposed on the thin film transistor array display module 16. In the pressure-sensing module 10, the substrate 28 and the pressure sensor 30 are also sequentially disposed on the middle frame 26, but the pressure sensor 30 is also separated from the plastic frame 12. The thin-film transistor array display module 16 and the pressure sensor 30 can be used to establish a pressure-sensitive capacitor. When the finger presses the glass substrate 24, the thin-film transistor array display module 16, the first transparent electrode series layer 18, and the transparent substrate 20 Both the second transparent electrode tandem layer 22 and the glass substrate 24 are deformed toward the optical film layer 14 to change the pressure sensitive capacitance, and the pressure is calculated according to this. However, because the pressure sensor 30 is disposed on the center frame 26, the material of the plastic frame 12 needs to be restricted and cannot be a conductor, and the flatness, opening size and number of the center frame 26 need to be included In consideration, in addition, the problems of assembly tolerance and mechanism deformation stability will become unstable factors affecting the pressure sensor 30.
另外，如第2圖所示，第2圖為先前技術之壓控式顯示裝置之結構剖視圖，此壓控式顯示裝置包含一金屬框體32、一基層膜34、複數壓力感測器36、一光學膜層38、一下偏振片40、一薄膜電晶體陣列顯示模組42、一上偏振片44與一玻璃基板46，其中基層膜34與光學膜層38設於金屬框體32中，壓力感測器36設於基層膜34上，光學膜層38與壓力感測器36彼此相隔，下偏振片40、薄膜電晶體陣列顯示模組42、上偏振片44與玻璃基板46依序設於光學膜層38上。薄膜電晶體陣列顯示模組42係與壓力感測器36建立壓感電容。當手指按壓玻璃基板46時，光學膜層38、下偏振片40、薄膜電晶體陣列顯示模組42、上偏振片44與玻璃基板46皆朝壓力感測器36產生形變，以改變壓感電容，並據此計算壓力大小。然而，當按壓力道過大，則壓感電容不再變化，造成壓力感測器36無法運作。In addition, as shown in FIG. 2, FIG. 2 is a cross-sectional view of a structure of a prior art voltage-controlled display device. This voltage-controlled display device includes a metal frame 32, a base film 34, a plurality of pressure sensors 36, An optical film layer 38, a lower polarizer 40, a thin film transistor array display module 42, an upper polarizer 44 and a glass substrate 46, wherein the base film 34 and the optical film layer 38 are disposed in a metal frame 32, and the pressure The sensor 36 is disposed on the base film 34.

以下介紹第一實施例之運作方式，本發明採自容方式偵測壓力。在壓感式顯示裝置48受到外部壓力時，壓感式顯示裝置48係先改變第一電容C1以偵測外部壓力，此時若外部壓力過大使所有第一電容C1停止變動時，壓感式顯示裝置48利用外部壓力繼續往壓感裝置50施壓，以改變第二電容C2並藉此偵測外部壓力。此外，由於壓感裝置50之設於壓感式顯示裝置48之底部，並非與壓感式顯示裝置48完全相隔，故可避免將機構相關因素列入影響壓感裝置之考量。The operation of the first embodiment is described below. The present invention adopts a self-capacitive method to detect pressure. When the pressure-sensitive display device 48 is subjected to external pressure, the pressure-sensitive display device 48 first changes the first capacitor C1 to detect external pressure. At this time, if the external pressure exceeds the ambassador, all the first capacitors C1 stop changing. The display device 48 continues to apply pressure to the pressure-sensitive device 50 by using external pressure to change the second capacitor C2 and thereby detect external pressure. In addition, since the pressure-sensitive device 50 is disposed on the bottom of the pressure-sensitive display device 48 and is not completely separated from the pressure-sensitive display device 48, it is possible to avoid including the mechanism-related factors into consideration of affecting the pressure-sensitive device.

When the 88 is pressed to change the first capacitor C1, when the insulating substrate 86 and the optical film layer 58 are in contact with each other to stop all the first capacitors C1 from changing, the transparent substrate 76 of the display module 56 uses external pressure to the conductive base and the first capacitor C1. The second pressure sensing unit 84 applies pressure to change the third capacitor C3. When the second pressure sensing unit 84 and the conductive base contact each other to stop the third capacitor C3 from changing, the transparent substrate 76 of the display module 56 uses external pressure to the conductive base. Apply pressure to the insulating elastic adhesive layer 64 to compress the insulating elastic adhesive layer 64 to change the second capacitor C2. In the present invention, the first pressure-sensitive unit 62 is installed on the bottom of the insulating base 52 to avoid including the flatness of the base 68, the size and number of openings, the assembly tolerance, and the stability of the mechanism deformation into the factors affecting the pressure-sensitive layer.
綜上所述，本發明於電容式壓感顯示裝置中形成至少二階段式之電容，以偵測過大之按壓力道，並將壓感裝置設於壓感式顯示裝置之底部，以避免將機構相關因素影響壓感裝置之運作效果。In summary, the present invention forms at least two-stage capacitors in a capacitive pressure-sensitive display device to detect an excessively large pressing pressure channel, and sets the pressure-sensitive device on the bottom of the pressure-sensitive display device to avoid Institutional factors affect the operation of the pressure sensitive device.
