Description
本發明是有關於一種觸控單元。 The invention relates to a touch unit.
近年來，輕薄的平面顯示器已廣泛應用於各種電子產品之中，而為了達到使用便利性、外觀簡潔以及多功能的目的，許多資訊產品已由傳統之鍵盤或滑鼠等輸入裝置，轉變為使用觸控面板作為輸入裝置。 In recent years, thin and light flat panel displays have been widely used in various electronic products, and many information products have been converted from traditional keyboards or mouse input devices to use for the convenience of use, compact appearance, and versatility. The touch panel is used as an input device.
觸控面板的操作原理為，當導體物件接觸到觸控面板的時候，觸控面板內的觸控單元的電性會發生變化，並導致觸控單元的偏壓改變。此電性上的改變會轉換為控制訊號傳送至外部的觸控晶片或控制電路板上，並經由處理器進行資料處理，以運算出導體物件的位置。對此，如何能再進一步改良觸控面板的結構已成為當前相關領域的熱門議題。 The operation principle of the touch panel is that when the conductive object contacts the touch panel, the electrical properties of the touch unit in the touch panel change, and the bias of the touch unit changes. This electrical change is converted to a control signal that is transmitted to an external touch wafer or control circuit board and processed by the processor to calculate the position of the conductor object. In this regard, how to further improve the structure of the touch panel has become a hot topic in the current related fields.

For example, the fourth electrode pattern 124A and the tenth electrode pattern 134A are symmetrically disposed on both sides of the first touch electrode 110A, and the areas of the fourth electrode pattern 124A and the tenth electrode pattern 134A are different from each other.
透過上述第一觸控電極110A與第一電極單元122、第二電極單元124、第三電極單元132及第四電極單元134的配置關係，可提升觸控單元100A的觸控識別性，並進而提升觸控單元100A的觸控靈敏度，以下將以第一電極單元122為例說明。 Through the arrangement relationship between the first touch electrode 110A and the first electrode unit 122, the second electrode unit 124, the third electrode unit 132, and the fourth electrode unit 134, the touch recognition of the touch unit 100A can be improved, and further The touch sensitivity of the touch unit 100A is improved. The first electrode unit 122 will be described below as an example.
於觸控原理中，第一觸控電極110A與第二觸控電 極120A的第一電極單元122交互產生的電容值會與第一電極圖案122A、第二電極圖案122B及第三電極圖案122C的面積呈正相關，進一步來說，兩者大致成正比關係。此外，由於第一電極圖案122A、第二電極圖案122B及第三電極圖案122C的面積不同，故其與第一觸控電極110A所分別產生的電容值也會不同。例如，由於第一電極圖案122A的面積大於第三電極圖案122C的面積，故第一電極圖案122A與第一觸控電極110A所產生的電容值會大於第三電極圖案122C與第一觸控電極110A所產生的電容值。 In the touch principle, the first touch electrode 110A and the second touch power The capacitance value generated by the first electrode unit 122 of the pole 120A is positively correlated with the areas of the first electrode pattern 122A, the second electrode pattern 122B, and the third electrode pattern 122C. Further, the two are approximately proportional to each other. In addition, since the areas of the first electrode pattern 122A, the second electrode pattern 122B, and the third electrode pattern 122C are different, the capacitance values respectively generated by the first electrode pattern 122A and the first touch electrode 110A are different. For example, since the area of the first electrode pattern 122A is larger than the area of the third electrode pattern 122C, the capacitance values generated by the first electrode pattern 122A and the first touch electrode 110A may be greater than the third electrode pattern 122C and the first touch electrode. The capacitance value produced by 110A.
因此，雖然第一電極單元122、第二電極單元124、第三電極單元132及第四電極單元134分別是以單一走線連接至觸控晶片，然而由於其電極圖案的面積不相同，故第一觸控電極110A與所對應的電極圖案組合可產生不相同的電容值，藉以使觸控晶片可識別位於第一觸控電極110A、第二觸控電極120A及第三觸控電極130的觸控操作。 Therefore, although the first electrode unit 122, the second electrode unit 124, the third electrode unit 132, and the fourth electrode unit 134 are respectively connected to the touch wafer by a single trace, the area of the electrode pattern is different, so The combination of the touch electrodes 110A and the corresponding electrode patterns can generate different capacitance values, so that the touch wafer can recognize the touches of the first touch electrodes 110A, the second touch electrodes 120A, and the third touch electrodes 130. Control operation.
具體而言，每兩個位於第一觸控電極110A相對兩側的電極圖案可成一組，以供觸控晶片識別並判斷觸控位置。例如，第1圖中，當有觸控操作落於第一電極圖案122A與第七電極圖案132A上或是其周邊時，由於第一電極圖案122A及第七電極圖案132A與第一觸控電極110A所產生的電容值會異於其他組電極圖案與第一觸控電極110A所產生的電容值，故觸控晶片可依據電容值發生改變的位置，而識別並判斷出觸控操作的具體位置。換言之，由於各電極單元的電極圖案可與第一觸控電極110A產生不相同的電容值，故觸控晶片可識別所 進行的觸控操作是對應於第一觸控電極110A與哪一組的電極圖案。 Specifically, each of the two electrode patterns on opposite sides of the first touch electrode 110A may be grouped for the touch wafer to recognize and determine the touch position. For example, in FIG. 1 , when the touch operation falls on the first electrode pattern 122A and the seventh electrode pattern 132A or the periphery thereof, the first electrode pattern 122A and the seventh electrode pattern 132A and the first touch electrode are The capacitance value generated by the 110A is different from the capacitance values generated by the other group electrode patterns and the first touch electrode 110A. Therefore, the touch wafer can identify and determine the specific position of the touch operation according to the position where the capacitance value changes. . In other words, since the electrode patterns of the electrode units can generate different capacitance values from the first touch electrodes 110A, the touch wafer can recognize the The touch operation performed is an electrode pattern corresponding to which group of the first touch electrodes 110A.
除此之外，藉由各電極單元的電極圖案與第一觸控電極所產生之電容值具有識別性，可使觸控晶片對判斷觸控操作位置的靈敏度提升。此外，由於各電極單元的電極圖案與第一觸控電極所產生之電容值具有識別性，第一觸控電極與各電極單元可分別以單一走線連接至觸控晶片，藉以減少觸控單元的走線使用量，使得觸控單元的空間配置可更靈活。 In addition, by the identification of the capacitance values generated by the electrode patterns of the electrode units and the first touch electrodes, the sensitivity of the touch wafer to determining the position of the touch operation can be improved. In addition, since the electrode patterns of the electrode units and the capacitance values generated by the first touch electrodes are discriminative, the first touch electrodes and the electrode units can be respectively connected to the touch wafer by a single trace, thereby reducing the touch unit. The amount of wiring used makes the space configuration of the touch unit more flexible.
另一方面，依據觸控單元所應用之顯示面板的尺寸大小，觸控單元的排列可接續延伸，例如，請看到第2圖，其中第2圖為依據本發明的第二實施方式繪示觸控單元100B的上視示意圖。本實施方式與第一實施方式的至少一個差異點在於，觸控單元100B的電極圖案沿第一方向D1延伸排列，從而增加觸控單元100B的縱向尺寸，以使觸控單元100B可應用於更大尺寸的顯示面板。除此之外，本實施方式的觸控單元100B的排列也透過增加設置第一觸控電極110、第二觸控電極120及第三觸控電極130的數量，而沿第二方向D2再延伸，從而增加觸控單元100B的橫向尺寸。此外，第2圖中，所繪的第一觸控電極110於每一行(即第一方向D1上)的數量為兩個，然而，第2圖所繪的第一觸控電極110僅為例示，而非用以限制本揭露內容，本揭露內容所屬技術領域中具有通常知識者，可依實際需要，彈性選擇第一觸控電極110於每一行(即第一方向D1上)的數量。 On the other hand, according to the size of the display panel to which the touch unit is applied, the arrangement of the touch units can be extended.

In addition, the arrangement of the touch unit 100B of the present embodiment is further extended along the second direction D2 by increasing the number of the first touch electrodes 110, the second touch electrodes 120, and the third touch electrodes 130. Thereby increasing the lateral size of the touch unit 100B. In addition, in FIG. 2, the number of the first touch electrodes 110 is two in each row (ie, in the first direction D1). However, the first touch electrodes 110 depicted in FIG. 2 are merely examples. Rather than limiting the disclosure, those skilled in the art can flexibly select the number of first touch electrodes 110 in each row (ie, in the first direction D1) as needed.
