步驟510:利用第三電極進行自電容感測。在此步驟當中,可以令驅動電路模組112與感測電路模組113同時對一條或多條第三電極123進行自電容感測。本領域普通技術人員可以理解到,驅動電路模組112對每一條第三電極123發出驅動信號。同時,感測電路模組113可以量測每一條第三電極123的驅動信號,以便得到多個感測資訊元素所組成的壹維度陣列。當有外部導電物件139靠近某一條第三電極123時,該條第三電極123所發出的驅動信號的部分信號會被外部導電物件139傳導到外界去。因此,針對該條第三電極123所量測到感測信號會有所變化。
Step 510: Use the third electrode to perform self-capacitance sensing. In this step, the driving
步驟520:根據步驟510所取得的壹維度陣列和未有任何外部導電物件139近接時所量測的基準壹維度陣列,判斷是否有任何元素產生一定程度以上的變化。亦即判斷是否有外部導電物件靠近。若有的話,表示有靠近事件產生,亦即外部導電物件139靠近或接觸到該第三電極123附近的觸控螢幕120,流程走向步驟530。若沒有任何元素產生一定程度以上的變化時,則表示沒有任何靠近事件,流程走向可選的步驟525或回到步驟510。
Step 520: According to the one-dimensional array obtained in
可選的步驟525:由於沒有任何外部導電物件139近接該觸控螢幕120,所以暫停感測外部導電物件某一段期間,再回到步驟510。在某一些實施例當中,步驟525可以再包含判斷是否已經有多次沒有偵測到外部導電物件139近接該觸控螢幕120。如果是的話,可以再延長暫停感測的時間長度,以便減少耗電量。
Optional step 525: Since there is no external
步驟530:將第三電極123接地。在一實施例當中,可以將所
有的第三電極123全部接地或是接到某一直流電位。在另一實施例當中,可以將外部導電物件139所近接的第三電極123接地或是接到某一直流電位。
Step 530: ground the
步驟540:利用第一電極與第二電極進行互電容感測。在一實施例中,當所有的第三電極123全部接地或是接到某一直流電位時,本領域普通技術人員可以理解到,可以令驅動電路模組112輪流對多條第一電極121發出驅動信號。並且在每一條第一電極121發出驅動信號的同時,令感測電路模組113量測每一條第二電極122所感應的驅動信號,以便得到多個感測資訊元素所組成的壹維度陣列。當有外部導電物件139近接到某一條第一電極121與某一條第二電極122的交疊處時,會造成該處的彈性介電層124形變,讓該處附近的第三電極123更靠近該第二電極122。因此,有部分的驅動信號會經由接地的第三電極123傳導到該外部導電物件139,使得該條第二電極122所感應的驅動信號有所變化。據此,該壹維度陣列當中相應於該條第二電極122的感測資訊元素就有所變化。
Step 540: Use the first electrode and the second electrode to perform mutual capacitance sensing. In an embodiment, when all the
由於每一條第一電極121發出驅動信號時,可以得到相對應的壹維度陣列。把複數個壹維度陣列依照其所對應的第一電極121的位置進行排列,可以形成一個貳維度陣列。根據這個貳維度陣列與未有任何外部導電物件139近接時所量測的基準貳維度陣列,可以判斷出一或多個外部導電物件139在該觸控螢幕120的一或多個接觸事件。每一個接觸事件可以對應到一個位置或座標。
Since each
在另一實施例當中,若步驟530只將部份的第三電極123接地或接到某一直流電位時,可以只針對這些第三電極123所覆蓋的區域進行互電容感測。例如,在圖2A或圖2C的結構當中,當第一電極121與第三電極123
都平行於第一軸時,可以找出第三電極123接地區域所對應到的某些第一電極121。本領域普通技術人員可以理解到,可以令驅動電路模組112輪流對這些第一電極121發出驅動信號。同樣地,利用上述的互電容感測步驟,可以得到對應到部份觸控螢幕120的貳維度陣列。進而可以判斷出一或多個外部導電物件139在該觸控螢幕120的一或多個接觸事件。每一個接觸事件可以對應到一個位置或座標。
In another embodiment, if only part of the
由於外部導電物件139所施與的壓力大小不同,將可能導致彈性介電層124的形變量不同。當第二電極122與第三電極123越靠近時,電容量的變化也就越大。因此,還可以根據該變化量的大小,推測出該外部導電物件139所施予的壓力。在一實施例中,可以針對每一個接觸事件計算出壓力值。
Since the pressure applied by the external
步驟550:根據步驟540的偵測結果,判斷是否再次偵測到接觸事件。當外部導電物件139只靠近但未接觸觸控螢幕120時,可以在步驟510當中偵測到相應的靠近事件,但無法在步驟540當中偵測到相應的接觸事件時,流程走向可選的步驟560或回到步驟510。當在步驟510當中偵測到相應的靠近事件,而且也在步驟540當中偵測到相應的接觸事件時,流程走向步驟570。
Step 550: Determine whether a contact event is detected again according to the detection result of
步驟560:回報步驟510所偵測到的靠近事件到主機140。此步驟所回報的靠近事件,可以包含所對應的第三電極123在該觸控螢幕120的位置。
Step 560: Report the proximity event detected in
步驟570:回報步驟540所偵測到的接觸事件到主機140。此步驟所回報的一或多個接觸事件,可以分別包含位置或座標,也可以包含
壓力值。
Step 570: Report the contact event detected in
請參考圖6所示,其為根據本發明一實施例的觸控處理方法600的流程示意圖。該觸控處理方法600可以由該觸控處理裝置110實施,適用於圖3B的雙繞結構,也可以適用於圖2A至2C的三種結構。在一實施例中,是由該處理器模組114執行儲存於非揮發性記憶體內的程式來實現該觸控處理方法600。除非有因果關係,否則本申請並不限定任兩個步驟之間的執行順序。該觸控處理方法600利用先前提到的多個步驟,除非有特別說明,否則都可以適用先前的描述。

步驟610:利用第三電極進行自電容感測。在此步驟當中,可以令驅動電路模組112與感測電路模組113同時對一條或多條第三電極123進行自電容感測。本領域普通技術人員可以理解到,驅動電路模組112對每一條第三電極123的兩端發出驅動信號。同時,感測電路模組113可以量測每一條第三電極123兩端的驅動信號,以便分別得到多個感測資訊元素所組成的壹維度陣列。換言之,由第三電極123的第一端得到的稱之為第一端壹維度陣列,由第三電極123的另外的第二端得到的稱之為第二端壹維度陣列。當有外部導電物件139靠近某一條第三電極123時,該條第三電極123所發出的驅動信號的部分信號會被外部導電物件139傳導到外界去。因此,針對該條第三電極123所量測到感測信號會有所變化。當該外部導電物件139較靠近第一端時,相應的第一端感測資訊與第二端感測資訊的變化量是不同的。
Step 610: Use the third electrode to perform self-capacitance sensing. In this step, the driving
假設第三電極123平行於第一軸,則根據第一端感測資訊與第二端感測資訊的不同,可以取得外部導電物件139在第一軸的座標。或
者,先計算第一端感應資訊與基準第一端感測資訊的第一變化量,以及第二端感應資訊與基準第二端感測資訊的第二變化量,再根據第一變化量與第二變化量的差值,可以判斷外部導電物件139在第一軸的座標。
Assuming that the
此外,由於多條第三電極123是分別沿著第二軸排列,可以根據第一端壹維度陣列與基準第一端壹維度陣列,來計算外部導電物件139在第二軸的座標。或者是根據第二端壹維度陣列與基準第二端壹維度陣列,來計算外部導電物件139在第二軸的座標。
In addition, since the plurality of
本領域的普通技術人員可以理解到,當同一條第三電極123有兩個以上的外部導電物件139靠近時,上述的計算方式就不適用來計算靠近事件的位置,而只知道有靠近事件發生在該條第三電極123附近。換言之,本實施例所提供的觸控系統可以確實偵測到單一個外部導電物件139的靠近位置。以及當兩個以上的外部導電物件139在不同條第三電極123的兩個以上的靠近位置。
Those of ordinary skill in the art can understand that when there are more than two external
步驟620:判斷是否有外部導電物件靠近。只要在步驟610當中偵測到一或多個靠近事件發生,無論是否能夠確切發現其靠近位置,都可以認為有外部導電物件靠近,流程走向步驟530。否則,流程走向步驟525。
Step 620: Determine whether there is an external conductive object approaching. As long as one or more proximity events are detected in
步驟650:判斷靠近事件是否相應於接觸事件。理論上來說,當發現接觸事件時,必定有相應的靠近事件在步驟610當中被偵測到。如前所述,當有兩個以上的外部導電物件139在同一條第三電極123附近發生靠近事件時,步驟610只能判斷出一個靠近事件。但是在步驟540當中,卻可以偵測到相應的兩個以上的接觸事件。因此,當靠近事件座標的第一軸位
置與接觸事件座標的第一軸位置在一範圍之內,而兩個事件的第二軸位置在該範圍之外時,可以判斷該靠近事件有相應的接觸事件。
Step 650: Determine whether the approach event corresponds to the contact event. In theory, when a contact event is found, a corresponding proximity event must be detected in
在本實施例中,當靠近事件沒有相應的接觸事件時,代表該靠近事件所對應的外部導電物件139並沒有接觸到觸控螢幕120。因此,流程走向步驟660。否則,流程走向步驟570。在本實施例當中,若有接觸事件時,則不回報其相對應的靠近事件。
In this embodiment, when there is no corresponding contact event for the proximity event, it means that the external
步驟660:將步驟610所偵測到的靠近事件回報到主機140。如前所述,本實施例所提供的觸控系統可以確實偵測到單一個外部導電物件139的靠近位置,以及當兩個以上的外部導電物件139在不同條第三電極123的兩個以上的靠近位置。
Step 660: Report the proximity event detected in
