Description
本發明涉及一種觸控感測器的觸控點感知方法,尤指一種以量子穿隧電流判斷觸控的觸控點感知方法。The invention relates to a touch point sensing method of a touch sensor, in particular to a touch point sensing method using quantum tunneling current to judge touch.
查,目前市面上的觸控感測器為增加使用者的觸控靈敏度,例如使用者以該觸控感測器進行繪圖作業時,使用者可針對該觸控感測器施以不同的力度大小,來做為繪圖筆觸的差異。又,以CN 110297567來說,該案揭露了以電阻式面板作為主要實施結構,惟根據該專利說明書內容所述,可發現該觸控面板是透過壓力來感應電阻層中的電阻顆粒與導電電極接觸率的變化,來判斷觸控體的按壓力道。根據前述可知,電阻式觸控面板乃接觸式觸控,此觸控方式容易有精準度與靈敏度上的問題。再者,以電阻式觸控裝置進行繪圖作業時精密度相對較差,另外電阻式觸控裝置多為單點觸控,當前雖有以多點觸控的裝置,但裝置解析度較差。Check that the current touch sensor on the market is to increase the user’s touch sensitivity. For example, when the user uses the touch sensor for drawing operations, the user can apply different forces to the touch sensor The size is used as the difference in drawing strokes. Furthermore, in CN 110297567, the case discloses a resistive panel as the main implementation structure, but according to the content of the patent specification, it can be found that the touch panel senses the resistive particles and conductive electrodes in the resistive layer through pressure. The change of the contact rate is used to judge the pressing force of the touch body. According to the foregoing, the resistive touch panel is a contact touch, and this touch method is prone to accuracy and sensitivity problems. Furthermore, the precision of drawing operations with resistive touch devices is relatively poor. In addition, resistive touch devices are mostly single-touch. Although there are currently multi-touch devices, the resolution of the device is poor.
另外,TW I578202案則揭露使用電容式觸控面板的技術內容,惟該案為達判斷Z軸訊號變化的目的,因此於該電容式觸控面板上額外增設壓力感測層,藉此以判斷使用者的所施力度大小。惟,額外增設壓力感測層容易造成該觸控感測器的厚度被疊加,而無法令該觸控感測器達更為輕薄的目的。再者,電容式觸控面板於實施上,普遍受限於觸控體的材質,該觸控體須為導體,否則無法操控電容式觸控裝置。In addition, the TW I578202 case disclosed the technical content of using a capacitive touch panel. However, in this case, for the purpose of judging the change of the Z-axis signal, an additional pressure sensing layer was added to the capacitive touch panel to determine The amount of force applied by the user. However, adding an additional pressure sensing layer easily causes the thickness of the touch sensor to be superimposed, and cannot make the touch sensor lighter and thinner. Furthermore, the implementation of the capacitive touch panel is generally limited by the material of the touch body, and the touch body must be a conductor, otherwise the capacitive touch device cannot be controlled.
再者,現今壓電式觸控裝置係以壓電材料作為面板的基礎結構,惟壓電材料的訊號控制不穩定,易有操作準確度以及靈敏度等問題。又當前壓電材料多非光學等級之材料而不適用於觸控面板上。Moreover, the current piezoelectric touch devices use piezoelectric materials as the basic structure of the panel, but the signal control of the piezoelectric materials is unstable, which is prone to problems such as operation accuracy and sensitivity. In addition, most of the current piezoelectric materials are not optical grade materials and are not suitable for touch panels.

本發明詳細說明及技術內容,茲配合圖式說明如下:The detailed description and technical content of the present invention are described as follows in conjunction with the drawings:
請參閱圖1至圖6,本發明提供一種觸控點感知方法10,該觸控點感知方法10被應用於一觸控感測器30上,該觸控感測器30可應用於手機、平板、工業電腦等相關顯示產業的產品上,該觸控點感知方法10供該觸控感測器30判斷使用者的觸控方位以及觸控力度。1 to 6, the present invention provides a touch
於實施的初始,進入一步驟一11,提供該觸控感測器30以及一連接該觸控感測器30的訊號處理件40。具體說明,該觸控感測器30包含複數第一電極31,複數第二電極32,以及至少一設於該些第一電極31與該些第二電極32間的絕緣質33。其中,該些第一電極31具有導電特性,該些第一電極31相互間隔設置且呈平行排列。該些第二電極32同樣具有導電特性,該些第二電極32之間同樣採間隔設置,且該些第二電極32之間的排列方向互為平行。又,該些第二電極32具有一第一延伸方向321,該些第一電極31具有一第二延伸方向311,該第一延伸方向321與該第二延伸方向311為垂直,即該些第二電極32的排列方向相對該些第一電極31的排列方向為垂直。進一步地,該些第一電極31與該些第二電極32為上下間隔設置,且每一該第一電極31與每一該第二電極32之間不接觸。承上,該些第一電極31與該些第二電極32分別被施予能量,而令該些第一電極31與該些第二電極32之間存有能量差。舉例來說,該些第一電極31與該些第二電極32可分別為一低電位以及一高電位。反之,該些第二電極32亦可被設計為低電位,該些第一電極31則被施予較高的能量而為高電位。該些第一電極31與該些第二電極32之間的能量差並不足以使該些第一電極31的電子或該些第二電極32的電子跨越該絕緣質33而形成電流,即該些第一電極31與該些第二電極32於未受力時,該觸控感測器30處於穩態。At the beginning of the implementation, a
另外,該絕緣質33用以分隔該些第一電極31與該些第二電極32,且該絕緣質33的電阻率大於該些第一電極31的電阻率與該些第二電極32的電阻率。該絕緣質33為一可變形且具良好彈性恢復力的材料,例如矽膠、壓克力等。該絕緣質33實際上為一未額外摻雜導電材料的物質,該絕緣質33於受壓迫形變時電阻率維持不變。又,該絕緣質33受壓迫時將產生形變,同時該些第一電極31與該些第二電極32之間的距離亦被改變,當該絕緣質33不再受壓迫時,該絕緣質33將復歸原樣,同時該些第一電極31與該些第二電極32之間的距離亦復歸至原始距離。再者,該訊號處理件40與該觸控感測器30資訊連接,該訊號處理件40可為一MCU,該訊號處理器用以偵測該觸控感測器30是否受觸控,並於該觸控感測器30受觸控後對訊號進行分析與處理。In addition, the
進一步地,該觸控感測器30於未受力時,該些第一電極31與該些第二電極32被該絕緣質33分隔而具有一間距,該間距大於一量子穿隧距離34。即,該些第一電極31與該些第二電極32之間即便存有能量差,該些第一電極31中的電子與該些第二電極32中的電子亦無法跨越該量子穿隧距離34,而未產生一穿隧電流35。於此當下,該觸控感測器30處於穩態,而該訊號處理件40未接獲該穿隧電流35,因此該訊號處理件40判斷該觸控感測器30未受觸控。Furthermore, when the
接著,進入一步驟二12,接受一觸控者50對該觸控感測器30施力。於此須說明的是,本文圖式所繪該觸控者50雖為使用者手指,但實際上於操作時亦可為一絕緣材料,例如一觸控筆。換句話說,本發明該觸控感測器30可接受導電物質或是非導電物質的施力。承上,該觸控感測器30於實施時可以該些第一電極31或是該些第二電極32的其中之一接受該觸控者50施力,使得該些第一電極31或該些第二電極32朝該絕緣質33方向擠壓。又,本文於後為方便說明遂先假設以該些第一電極31受力進行說明。至少其中一該第一電極31受力後,該第一電極31產生形變,隨外力的施加,該第一電極31與該些第二電極32之間的距離被改變。當該第一電極31與該些第二電極32之間的垂直距離被縮短至該量子穿隧距離34時,該第一電極31與該些第二電極32之間的電子可跨過該絕緣質33,使得該第一電極31與該些第二電極32之間的電子生成該穿隧電流35。一實施例中,該穿隧電流35的計算可如後:
,其中,I為穿隧電流,k為波數(wave number),d為該些第一電極31與該些第二電極32之間的該間距。此時,該訊號處理件40經該觸控感測器30接獲該穿隧電流35的產生,該訊號處理件40判斷該觸控感測器30由未受觸控轉變為受觸控狀態。
Then, proceed to a step two 12 to accept a
進入一步驟三13,該訊號處理件40以該穿隧電流35流經的其中一該第一電極31與其中一該第二電極32定義出一縱軸位置313與一橫軸位置322。其中,該縱軸位置313與該橫軸位置322可分別對應該觸控感測器30於生成該穿隧電流35的X軸座標以及Y軸座標,並表示該穿隧電流35位置數據的數位資訊。進一步舉例來說,該訊號處理件40可依據出廠時的設定,將該些第一電極31視為該觸控感測器30的X軸,該些第二電極32視為該觸控感測器30的Y軸,當該穿隧電流35流經其中一該第一電極31以及其中一該第二電極32時,該訊號處理件40基於前述設定,以其中一該第一電極31定義出該縱軸位置313,並以其中一該第二電極32定義出該橫軸位置322,並取得該觸控者50的一觸控點方位。反之,該訊號處理件40亦可以該些第二電極32視為該觸控感測器30的X軸,該些第一電極31視為該觸控感測器30的Y軸,並以該穿隧電流35流經的其中一該第二電極32定義出該縱軸位置313,並以該穿隧電流35流經的其中一該第一電極31定義出該橫軸位置322。於後,該訊號處理件40以該縱軸位置313以及該橫軸位置322取得該觸控點方位。同一時間,該訊號處理件40基於該穿隧電流35大小得知該觸控者50的一觸控力道,即該穿隧電流35大時,該訊號處理件40判斷該觸控力道較大,當該穿隧電流35小時,該訊號處理件40判斷該觸控力道較小。Entering a step three 13, the
承此,本發明透過該觸控者50施力使該穿隧電流35產生,以判斷該觸控者50的該觸控點方位,並基於該穿隧電流35大小得知該觸控力道,使得該觸控感測器30可做更為具體的觸控辨識。再者,本發明不以習用電容感應式結構或是電阻接觸式結構感知訊號,而以該觸控感測器30接受該觸控者50的施力。又,本發明所揭該觸控感測器30的操作準確度與解析度亦優於習用以電阻架構或以電容架構實施的觸控感測器30。Accordingly, in the present invention, the tunneling current 35 is generated by the
一實施例中,復請參閱圖7至圖9,該觸控感測器30具有二基板36,該二基板36分別對應該些第一電極31與該些第二電極32設置,該二基板36的其一設於該些第一電極31遠離該絕緣質33一側,該二基板36的另一則設於該些第二電極32遠離該絕緣質33一側。於本實施例中,該二基板36可以導體實施,又該步驟二12包含一子步驟121,該訊號處理件40基於該觸控感測器30受力側的電容值變化判斷該觸控者50為導體或非導體。詳細說明,假設該觸控者50為導體時,該觸控者50未接觸該位於受力側的該基板36,該基板36本身即存有一定的電容值,一旦該觸控者50接觸該基板36後,該基板36與該觸控者50串聯,該基板36本身的電容值產生變化並下降。此時,該訊號處理件40感知該基本的電容值發生變化,而判斷該觸控者50為導體。反之,當該觸控者50為非導體時,該觸控者50接觸該基板36後,該基板36不會與該觸控者50產生電連接,因此該基板36本身的電容值不會產生變化,承此,該訊號處理件40則判斷該觸控者50為非導體。值得注意的是,本發明該訊號處理件40為具體判斷該觸控感測器30的受力側,該訊號處理件40常態下對該二基板36進行電容值偵測,一旦該二基板36的其中一發生電容值變化,則可基於該基板36的設置位置,判斷出該觸控感測器30的受力側。In one embodiment, referring to FIGS. 7 to 9 again, the
另外,一實施例中,該訊號處理件40可具有一記憶儲存功能,或是該訊號處理件40可資訊連接一記憶體(圖中未示),使該訊號處理件40可存有一電流條件。該訊號處理件40基於該電流條件比對所接獲的該穿隧電流35,並以符合該電流條件的該穿隧電流35所流經的其中一該第一電極31與其中一該第二電極32定義該縱軸位置313與該橫軸位置322。舉例地說,該電流條件可為一固定電流數值,即該觸控者50觸控該觸控感測器30後,該穿隧電流35未達到該電流條件時,該訊號感測器則忽略該穿隧電流35,並判斷該觸控感測器30未受觸控。以圖9來說,該觸控感測器30受該觸控者50觸控後,該觸控感測器30產生複數該穿隧電流35,又假設該訊號處理件40基於該電流條件過濾複數該穿隧電流35,令複數該穿隧電流35中僅有產生最大電流值者通過該電流條件,使得該訊號處理件40以產生前述該穿隧電流35的該第一電極31與該第二電極32判斷該觸控點方位。承此,本發明可藉由設定該電流條件的數值,以避免該觸控感測器30受誤觸的情況。再者,當該觸控者50以一定力道施力於該觸控感測器30後,該觸控感測器30所生成的該穿隧電流35符合該電流條件時,該訊號處理件40此時方判斷該觸控感測器30受觸控,並以該穿隧電流35所流經的其中一該第一電極31與其中一該第二電極32定義該縱軸位置313與該橫軸位置322。更進一步地,當複數該穿隧電流35皆符合該電流條件時,該訊號處理件40則可判斷該觸控感測器30接受多點觸控,並以符合該電流條件的複數該穿隧電流35判斷每一該縱軸位置313以及每一該橫軸位置322。In addition, in one embodiment, the
另外一方面,當有複數該穿隧電流35符合該電流條件,而該觸控感測器30被設定為僅能進行單點觸控時。該訊號處理件40於接獲該觸控感測受力區域所產生的複數該穿隧電流35,以複數該穿隧電流35中的最大者進行該觸控點方位的判斷。換句話說,該訊號處理件40僅以複數該穿隧電流35中的最大者進行觸控點感知,而其餘的複數該穿隧電流35則會被忽略。On the other hand, when there are a plurality of the tunneling current 35 that meet the current condition, and the
承上,由前述可知,該觸控點感知方法10是基於該穿隧電流35的產生來得知觸控,基於相同技術構想,本發明亦提供另一觸控點感知方法20,請參圖3、圖10至圖13。該觸控點感知方法20包含一步驟一21,提供一觸控感測器30以及一連接該觸控感測器30的訊號處理件40。其中,該訊號處理件40同樣與該觸控感測器30連接,且該訊號處理件40亦用以偵測該觸控感測器30的電流訊號,於此不再贅述。該觸控感測器30包含複數觸控元301,該些觸控元301以一排列形式設置,所述該排列形式可以為任意陣列方式排列,且該觸控元301於該排列形式下將不致令該觸控感測區產生感知盲區。舉例來說,該排列形式可以為一矩陣陣列,或是一菱形陣列。In summary, it can be seen from the foregoing that the touch
進一步來說,請參圖5、圖10至圖13,每一該觸控元301包含一第一電極31,一第二電極32,以及一設於該第一電極31與該第二電極32之間的絕緣質33。該第一電極31、該第二電極32以及該絕緣質33的設置方式與前述相同,於此不再贅述。又,該第一電極31與該第二電極32於未受力時,該第一電極31與該第二電極32相距有該間距,使得該第一電極31與該第二電極32之間大於該量子穿隧距離34,而未產生該穿隧電流35。此時,該訊號處理件40未接獲該穿隧電流35,因此判斷該觸控感測器30未受觸控。Further, referring to FIGS. 5 and 10 to 13, each of the
進入一步驟二22,接受該觸控者50對該觸控感測器30施力,該觸控感測器30以至少一該觸控元301的該第一電極31或是該第二電極32的其中一者作為受力側,令位於受力側的電極朝同一該觸控元301的該絕緣質33擠壓,使得同一該觸控元301的該第一電極31與該第二電極32之間的間距小於該量子穿隧距離34,以致該第一電極31與該第二電極32之間的電子可跨越該量子穿隧距離34,進而產生該穿隧電流35。同一時間,該訊號處理件40經該觸控感測器30接獲該穿隧電流35產生,並判斷該觸控感測器30由未受觸控轉為已受觸控。Enter a step two 22, accept the
接著,進入一步驟三23,該訊號處理件40基於產生有該穿隧電流35的其中一該觸控元301於該排列形式內的位置取得一觸控點方位。舉例來說,產生有該穿隧電流35的其中一該觸控元301,其排列於該矩陣陣列之中,前述該觸控元301於該矩陣形式內的位置,即對應出該觸控者50的觸控點方位。同一時間,該訊號處理件40基於該穿隧電流35大小得知該觸控者50的一觸控力道,即該穿隧電流35大時,該訊號處理件40判斷該觸控力道較大,當該穿隧電流35小時,該訊號處理件40判斷該觸控力道較小。Then, proceed to a step three 23, the
承上,請參閱14與圖15,一實施例中,每一該觸控元301同樣設置該二基板36,該二基板36分別對應該第一電極31與該第二電極32設置,該二基板36可為一導體材料,而令該訊號處理件40可基於該二基板36上的電容變化判斷該觸控者50是否為導體。具體地說,該步驟二22包含一子步驟221,於該子步驟221中,該訊號處理件40基於該觸控感測器30受力側的電容值變化進行導體、非導體判斷。於本實施例中,該觸控感測器30同樣可以該些觸控元301的該些第一電極31側作為受力側,亦可以該些觸控元301的該些第二電極32側作為受力側。又如同本文前段所述,該訊號處理件40檢測受力側的該基板36的電容值變化,當該觸控者50接觸該觸控感測器30時,該基板36的電容值產生改變,該訊號處理件40判斷該觸控者50為導體。反之,當該觸控者50接觸該導體時,該基板36的電容值未產生變化,該訊號處理件40則判斷該觸控者50為非導體。Continuing, please refer to Figures 14 and 15. In one embodiment, each of the
再另一方面,於本實施例中的該訊號處理件40同樣存有該電流條件,該訊號處理件40同樣基於該電流條件比對所接獲的該穿隧電流35,並僅以符合該電流條件的該穿隧電流35流經的該觸控元301判斷該觸控點方位,其詳細判斷方式就如本文前段所述,不再詳述。於本實施例中,透過該訊號處理件40比對該電流條件,可避免使用者因誤觸該觸控感測器30而被判斷為該觸控點方位的情況。另外,假設該觸控感測器30具有多點觸控功能時,當有複數該穿隧電流35符合比對該電流條件時,該訊號處理件40可判斷為多點觸控。On the other hand, the
再一實施例中,當有複數該穿隧電流35符合該電流條件,而該觸控感測器30被設定為僅能進行單點觸控時。該訊號處理件40於接獲該觸控感測受力區域所產生的複數該穿隧電流35,同樣以複數該穿隧電流35中的最大者進行該觸控點方位的判斷。本實施例的具體實施方式,可參本文前段所言,不再詳述。In still another embodiment, when there are a plurality of the
