M413915 五、新型說明： 【新型所屬之技術領轉是 [0001] 本創作是有關於一種感測結構，且特別是有關於一 種具有主從關係的感測結構。 【先前技術】 [0002] 觸控螢幕（touch screen )和傳統螢幕最大的不同 就是觸控螢幕是雙向的輸出入裝置，可以輸出畫面，同 時也能輸入指令，利用手指在螢幕上點選即可操作電腦 ，這要比鍵盤滑鼠要來的更直覺，也徹底改變電腦與手 機的操作習慣。 [0003] 多點觸控螢幕具有感測結構，感測結構由多個感測 器所組成，感測器用以感測多點觸控螢幕的觸控位置。 當多根手指接觸多點觸控螢幕時，多點觸控螢幕的觸控 位置分別產生感應信號。同一時間，觸控位置所對應的 感測器分別接收感應信號，感測器的内部分別具有轉換 器及處理器，轉換器可將感應信號轉換成感應資料，處 理器可計算感應資料以取得對應的觸控位置。因此，使 用者可透過多根手指在多點觸控螢幕上完成圖像應用控 制，例如用多根手指縮放或旋轉圖片，用三根手指更換 圖片，用四根手指檢視所有開啟圖片。 [0004] 由此看來，感測結構的感測器數量越多，則同一時 間可接收的感應信號也越多，可計算取得的觸控位置也 越多。由於，可靠度（Re liability )的簡單定義是『 在特定時間内，達到系統某種運作要求的機率』，因此 ，當感測結構的感測器數量越多時，也就代表感測結構 表單編號A0101 第3頁/共14頁 100年08月17日修正替换頁 [0005] 的感測可靠度越高。 然而，現有岛各感測器均將感應資料傳铪 後端處理線路（如包括控制器），因此隨著感測器增加將 會增加後端處理線路的複雜度（如控制器接腳增多）且整 個感測結構在設計完成後即不容易進行修改（如控制器接 腳數已固定而不易增加或減少感測器）。 [0006]M413915 V. New description: [New technology belongs to [0001] This creation is about a sensing structure, and in particular, it relates to a sensing structure with a master-slave relationship. [Prior Art] [0002] The biggest difference between the touch screen and the traditional screen is that the touch screen is a bidirectional input/output device that can output images, and can also input commands and use the finger to click on the screen. Operating the computer, this is more intuitive than the keyboard mouse, and completely changes the operating habits of the computer and mobile phone. [0003] A multi-touch screen has a sensing structure, and the sensing structure is composed of a plurality of sensors for sensing a touch position of the multi-touch screen. When multiple fingers touch the multi-touch screen, the touch positions of the multi-touch screen respectively generate sensing signals. At the same time, the sensors corresponding to the touch positions respectively receive the sensing signals, and the sensors respectively have a converter and a processor therein, and the converter can convert the sensing signals into sensing materials, and the processor can calculate the sensing data to obtain corresponding signals. Touch location. Therefore, the user can control the image application on the multi-touch screen through multiple fingers, such as zooming or rotating the image with multiple fingers, replacing the image with three fingers, and viewing all the open images with four fingers. [0004] From this point of view, the more sensors of the sensing structure, the more sensing signals can be received at the same time, and the more touch positions can be calculated. Since the simple definition of Re liability is “the probability of reaching a certain operational requirement of the system within a certain time”, the more the number of sensors in the sensing structure, the more representative of the sensing structure form. No. A0101 Page 3 of 14 The correction reliability of the replacement page [0005] on August 17, 100 is higher. However, the sensors on the existing islands transmit the sensing data to the back-end processing lines (including the controller), so as the sensor increases, the complexity of the back-end processing lines (such as the number of controller pins) increases. And the entire sensing structure is not easy to modify after the design is completed (such as the number of controller pins is fixed and it is not easy to increase or decrease the sensor). [0006]
