Description
本發明大體而言係關於用於計算系統之輸入裝置,且更特定而言,係關於能夠製造於基板之單側上的互電容多點觸摸式感測器面板。
目前有許多類型之輸入裝置可用於執行計算系統中之操作,諸如按鈕或按鍵、滑鼠、軌跡球、觸摸式感測器面板、操縱桿、觸控螢幕及類似物。特定而言,觸控螢幕由於其操作容易性及多用途性以及其下降之價格而變得日益普及。觸控螢幕可包含觸摸式感測器面板,其可為具有觸敏表面之透明面板。觸摸式感測器面板可定位於顯示器螢幕之前方,使得觸敏表面覆蓋顯示器螢幕之可觀看區域。觸控螢幕可允許使用者藉由用手指或尖筆簡單觸碰顯示器螢幕而做出選擇並移動游標。大體而言,觸控螢幕可辨識顯示器螢幕上的觸碰及觸碰之位置,且計算系統可解譯該觸碰並隨後基於觸碰事件執行動作。
觸摸式感測器面板可實施為由多個驅動線(例如,列)交叉於多個感測線(例如,行)形成之像素陣列,其中驅動線及感測線由介電材料分離。此觸摸式感測器面板之實例描述於申請人在2007年1月3日申請
之題為「雙側觸敏面板及撓性電路結合」的第11/650,049號共同待決美國申請案中,該申請案之內容以引用方式併入本文。然而,具有形成於單個基板之底部及頂部側上之驅動線及感測線的觸摸式感測器面板可能造價昂貴。此額外費用之一原因在於必須在玻璃基板之兩側上執行薄膜處理步驟,其要求在另一側經處理時針對已處理側之保護性措施。另一原因為撓性電路製造及連接至基板兩側所需之結合的成本。
本發明係關於一種實質透明之觸摸式感測器面板,其具有製造於一基板之單側上的用於偵測單點觸摸或多點觸摸事件(一或多個手指或其它物件約在同時在一觸敏表面上在不同位置處之觸摸)的共平面單層觸摸式感測器。為避免不得不在同一基板之相反兩側上製造實質上透明之驅動線及感測線,本發明之實施例可在基板之同一側上之共平面單層上形成驅動線及感測線。驅動線及感測線可製造為在一第一定向上的成行圖案及在一第二定向上的插線,其中在該第一定向上之每一成行圖案連接至該觸摸式感測器面板之邊界區域中之一單獨金屬跡線,且在該第二定向上之多個列中的每一列中的所有插線使用該觸摸式感測器面板之邊界區域中之一單獨金屬跡線(或其它導電材料)連接在一起。該等邊界區域中之該等金屬跡線可與該等插線及行形成於該基板之同一側上,但藉由一介電層與該等插線及成行圖案分離。金屬跡線可允許插線及成行圖案路由至基板之同一短邊緣,使得小型撓性電路可結合至基板之僅一側上之小區域。

在較佳實施例之以下描述中,參看形成其一部分的隨附圖式,且其中其展示可實踐本發明之特定實施例。應理解,在不脫離本發明之實施例之範疇的情況下,可利用其他實施例且可進行結構改變。
本發明係關於一種實質上透明之觸摸式感測器面板,其具有製造於基板之單側上之用於偵測單點觸摸或多點觸摸事件(一或多個手指或其它物件約同時於觸敏表面上不同位置處之觸摸)的共平面單層觸摸式感測器。為避免不得不在同一基板之相反兩側上製造實質上透明之驅動線及感測線,本發明之實施例可在基板之同一側上之共平面單層上形成驅動線及感測線。驅動線及感測線可製造成在第一定向上的成行圖案及在第二定向上的插線,其中第一定向上之每一成行圖案連接至觸摸式感測器面板之邊界區域中單獨金屬跡線,且第二定向上之多個列中每一列中之所有插線使用觸摸式感測器面板之邊界區域中之單獨金屬跡線(或其它導電材料)連接在一起。邊界區域中之金屬跡線可與該等插線及行形成於基板之同一側上,但藉由介電層與插線及成行圖案分離。金屬跡線可允許插線及成行圖案路由至基板之同一短邊緣,使得小型撓性電路可結合至基板之僅一側上之小區域。
儘管本文可以互電容多點觸摸式感測器面板來描述本發明之一些實施例,但應了解本發明之實施例不限於此,而是另外適用於自電容感測器面板及單點觸摸式感測器面板。此外,儘管本文可以具有多列及多行之觸摸式感測器正交陣列來描述感測器面板中之觸摸式感測器,但本發明之實施例不限於正交陣列,而是可大體適用於以任意數目之維度及定向排列之觸摸式感測器,包含對角、同心圓、三維以及隨機定向。
圖1a說明根據本發明實施例之具有製造於基板之單側上之共平面單層觸摸式感測器的例示性實質透明之觸摸式感測器面板100之部分視圖。在圖1a之實例中,展示具有八行(標記為a至h)及六列(標記為1
至6)的觸摸式感測器面板100,但應瞭解可使用任意數目之行及列。行a至h可大體為柱狀形狀,但在圖1a之實例中,每一行之一側包含經設計以在每一行中產生單獨區段的交錯邊緣及缺口。每一列1至6可由複數個不同插線或墊形成,每一插線包含與該插線相同材料之跡線,且該跡線路由至觸摸式感測器面板100之邊界區域以使一特定列中之所有插線能夠經由在該等邊界區域中延伸之金屬跡線(圖1a未圖示)連接在一起。此等金屬跡線可路由至觸摸式感測器面板100之一側上之小區域且連接至撓性電路102。如圖1a之實例所示,形成列之插線可以大體角錐形組態排列。例如在圖1a中,用於行a與b之間的列1-3之插線以倒角錐組態排列,而用於行a與b之間的列4-6之插線以直立角錐組態排列。
圖1a之行及插線可在共平面導電材料單層中形成。在觸控螢幕實施例中,導電材料可為諸如單層氧化銦錫(SITO)之實質透明材料,但亦可使用其它材料。SITO層可形成於覆蓋玻璃之背面上或單獨基板之頂部上。儘管為了簡化揭示內容之目的在本文中參考SITO,但應瞭解根據本發明之實施例亦可使用其它導電材料。
圖1b說明根據本發明實施例之包含在觸摸式感測器面板之邊界區域中延伸之金屬跡線104及106的例示性實質透明之觸摸式感測器面板100之部分視圖。應注意,圖1b中之邊界區域為清楚而放大。每一行a-h可包含SITO跡線108,其允許該行經由一通路(圖1b未圖示)連接至金屬跡線。每一行之一側包含經設計以在每一行中產生單獨區段之交錯邊緣114及缺口116。每一列插線1-6可包含SITO跡線110,其允許該插線經由一通路(圖1b未圖示)連接至金屬跡線。SITO跡線110可允許一特定列中之每一插線彼此自連接。因為所有金屬跡線104及106均形成於同一層上,所以其可全部路由至同一撓性電路102。
若觸摸式感測器面板100作為互電容觸摸式感測器面板操作,則
行a-h或列1-6可以一或多個激勵信號驅動,且邊緣電場線可形成於鄰近之行區域與列插線之間。圖1b中,應瞭解,儘管為說明目的僅展示行a與列插線1(a-1)之間的電場線112,但取決於正激勵哪些行或列,電場線可形成於其它鄰近之行與列插線(例如,a-2、b-4、g-5等)之間。因此應瞭解,每一行-列插線對(例如,a-1、a-2、b-4、g-5等)可表示兩電極像素或感測器,在該處電荷可自驅動電極耦合至感測電極上。當手指在此等像素之一上向下觸摸時,邊緣電場線中延伸越過觸摸式感測器面板之外殼的某些邊緣電場線由手指阻擋,從而減少耦合至感測電極之電荷量。可偵測此耦合電荷量之減少作為判定所得觸摸「影像」之部分。應注意,在圖1b所示之互電容觸摸式感測器面板設計中,無需單獨之參考接地,因此無需位於基板之背側上或單獨基板上之第二層。
觸摸式感測器面板100亦可作為自電容觸摸式感測器面板操作。在此實施例中,參考接地平面可形成於基板之背側上,與插線及行在同一側上但藉由介電質與插線及行分離,或在單獨基板上。在自電容觸摸式感測器面板中,每一像素或感測器具有一至參考接地之自電容,其可由於手指之存在而改變。在自電容實施例中,行a-h之自電容可被獨立感測,且列1-6之自電容亦可被獨立感測。
圖1c說明根據本發明實施例之行及列插線與觸摸式感測器面板之邊界區域中之金屬跡線的例示性連接。圖1c呈現如圖1b所示之「細節A」,且展示經由SITO跡線108及110連接至金屬跡線118之行「a」及列插線4-6。因為SITO跡線108及110藉由介電材料與金屬跡線118分離,所以形成於介電材料中之通路120允許SITO跡線連接至金屬跡線。
圖2a說明根據本發明實施例之展示經由介電材料222中的通路220連接之SITO跡線208與金屬跡線218的觸摸式感測器面板200之例示性
橫截面。圖2a呈現如圖1c所示之視圖B-B。
圖2b是根據本發明實施例之圖2a所示例示性橫截面之近視圖。圖2b展示一例示性實施例,其中SITO跡線208具有最大約每平方155歐姆之電阻率。在一實施例中,介電質222可為約1500埃之無機SiO2
,其可在較高溫度下處理且因此允許以較高品質濺鍍SITO層。在另一實施例中,介電質222可為約3.0微米之有機聚合物。1500埃之無機SiO2
可用於足夠小之觸摸式感測器面板以使得交叉電容(SITO跡線208與金屬跡線218之間)不成問題。
對於較大之觸摸式感測器面板(具有約3.5"或更大之對角線尺寸),交叉電容可成問題,從而產生僅可部分補償之誤差信號。因此對於較大之觸摸式感測器面板,具有較低介電常數之較厚介電層222(諸如約3.0微米之有機聚合物)可用於降低交叉電容。然而,使用較厚介電層可迫使在較低溫度下濺鍍SITO層,從而導致較低光學品質及較高電阻率。
再次參看圖1c之實例,行邊緣114及列插線4-6可在x維度中交錯,因為必須為連接列插線4與5之SITO跡線110留出空間。(應了解,在圖1c之實例中,列插線4實際為貼在一起之兩個插線。)為獲得最佳觸摸敏感度,可期望平衡像素a-6、a-5及a-4中電極之面積。然而,若行「a」保持為直線形,則列插線6可比列插線5或6細,且在像素a-6之電極之間將產生不平衡。
圖3說明根據本發明實施例之例示性行及鄰近列插線之俯視圖。可大體期望使像素a-4、a-5及a-6之互電容特性相對恆定,以產生保持於觸摸感測電路之量程內之相對均勻的z方向觸摸敏感度。因此,行面積a4
、a5
及a6
應大約與列插線面積4、5和6相同。為達成此情形,行區段a4
及a5
以及列插線4及5與行區段a6
以及列插線6相比,可在y方向上收縮,使得行片段a4
之面積匹配於行片段a5
及a6
之面積。換言之,
像素a4
-4將比像素a6
-6寬但比其短,a6
-6將較窄但較高。
自先前提及的圖式顯見,原始空間敏感度可在某種程度上失真。換言之,因為像素或感測器可在x方向上略微偏斜或未對準,所以在像素a-6上之最大化觸摸事件(例如,向下直接放置於像素a-6上之手指)之x座標可稍微不同於(例如)像素a-4上之最大化觸摸事件之x座標。因此,在本發明之實施例中,可在軟體演算法中修正此未對準,以重新映射像素並移除失真。
儘管典型觸摸式面板格柵尺寸可具有在5.0mm中心上排列之像素,但(例如)具有約6.0mm中心之較展開之格柵可為合意的,以減少觸摸式感測器面板中電連接之總數。然而,展開感測器圖案可導致錯誤之觸摸讀取值。
圖4a為針對在一具有寬間距之單列中兩個鄰近像素a-5及b-5,手指觸摸之x座標對在一像素處所見之互電容的曲線。圖4a中,曲線400表示在手指觸摸自左向右連續移動時在像素a-5處所見之互電容,且曲線402表示在手指觸摸自左向右連續移動時在像素b-5處所見之互電容。如預期,當手指觸摸直接經過像素a-5時在像素a-5處可見互電容之下降404,且當手指觸摸直接經過像素b-5時在像素b-5處可見互電容之類似下降406。若線408表示用於偵測觸摸事件之臨限值,則圖4a說明即使手指從未自觸摸式感測器面板之表面舉起,在410處亦可錯誤地表現為手指已瞬時離開該表面。此位置410可表示約在該兩個經展開像素之間的中點處之點。
圖4b為根據本發明實施例之針對在一具有寬間距之單列中兩個鄰近像素a-5及b-5,手指觸摸之x座標對在一像素處所見之互電容的已提供空間內插之曲線。如預期,當手指觸摸直接經過像素a-5時在像素a-5處可見互電容之下降404,且當手指觸摸直接經過像素b-5時在像素b-5處可見互電容之類似下降406。然而應注意,互電容值之上
升及下降比圖4a中更逐步地發生。若線408表示用於偵測觸摸事件之臨限值,則圖4b說明在手指自左向右移動經過像素a-5及b-5時,總是在像素a-5或b-5處偵測到觸摸事件。換言之,此觸摸事件之「模糊」有助於防止錯誤之無觸摸讀數值之出現。
在本發明之一實施例中,用於觸摸式感測器面板之覆蓋玻璃之厚度可增加以產生圖4b所示之空間模糊或過濾之部分或全部。
圖4c說明根據本發明實施例之可用於較大像素間距之例示性行及鄰近列插線圖案的俯視圖。圖4c說明在x方向上伸長之像素內使用鋸齒電極邊緣412的例示性實施例。鋸齒電極邊緣可允許邊緣電場線414存在於x方向上之較大區域上,使得可在x方向上之較大距離上由同一像素偵測觸摸事件。應瞭解圖4c之鋸齒組態僅為例示性的,且亦可使用諸如蜿蜒邊緣及類似物之其它組態。此等組態可進一步柔化觸摸圖案並如圖4b所示在鄰近像素之間產生額外之空間過濾及內插。
圖5說明根據本發明實施例之在結合至覆蓋玻璃之觸摸式感測器面板基板上之SITO的例示性堆疊。該堆疊可包含可由玻璃形成之觸摸式感測器面板基板500,其上抗反射(AR)膜510可形成於一側上且金屬502可沈積且圖案化於另一側上,以在邊界區域中形成匯流排線。金屬502可具有最大每平方0.8歐姆之電阻率。絕緣層504可隨後沈積於基板500及金屬502上。絕緣層可例如為具有1500埃厚度之SiO2
或3微米之有機聚合物。光微影可用於在絕緣體504中形成通路506,且導電材料508可隨後沈積且圖案化於絕緣體及金屬502之頂部上。可由諸如具有最大每平方155歐之電阻率之ITO的透明導電材料形成之單層導電材料508可比多層設計更透明,且可更容易製造。撓性電路512可使用諸如各向異性導電膜(ACF)之黏合劑514結合至導電材料508及金屬502。整個子組合件可隨後使用諸如壓敏黏合劑(PSA)之黏合劑518結合至覆蓋玻璃516及黑遮罩520。
在替代實施例中,如上所述之金屬、絕緣體、導電材料可直接形成於覆蓋玻璃之背側上。
圖6說明根據本發明實施例之可以上述觸摸式感測器面板操作之例示性計算系統600。可包含觸摸式感測器面板624及顯示裝置640(例如,LCD模組)之觸控螢幕642可經由整合地形成於感測器面板上之連接器或使用撓性電路連接至計算系統600中之其它組件。計算系統600可包含一或多個面板處理器602及周邊裝置604以及面板子系統606。該一或多個處理器602可包含例如ARM968處理器或具有類似功能性及能力之其它處理器。然而在其它實施例中,可替代地藉由諸如狀態機之專用邏輯來實施面板處理器功能性。周邊裝置604可包含(但不限於)隨機存取記憶體(RAM)或其它類型記憶體或儲存裝置、監視計時器及類似物。
面板子系統606可包含(但不限於)一或多個類比通道608、通道掃描邏輯610以及驅動器邏輯614。通道掃描邏輯610可存取RAM 612,自類比通道自主地讀取資料,及提供對類比通道之控制。此控制可包含多工化或以其它方式將觸摸式感測器面板624之感測線連接至類比通道608。另外,通道掃描邏輯610可控制驅動器邏輯及激勵信號被選擇性施加於觸摸式感測器面板624之驅動線。在一些實施例中,面板子系統606、面板處理器602以及周邊裝置604可整合至單個特殊應用積體電路(ASIC)中。
驅動器邏輯614可提供多個面板子系統輸出616且可呈現驅動高電壓驅動器618之專有介面。高電壓驅動器618可提供自低電壓位準(例如,互補金屬氧化物半導體(CMOS)位準)至較高電壓位準之位準移位,從而為雜訊減少目的而提供較佳之信號雜訊(S/N)比。面板子系統輸出616可發送至解碼器620及位準移位器/驅動器638,其可將一或多個高電壓驅動器輸出經由專有介面選擇性連接至一或多個面板列
或驅動線輸入622,且使得能夠使用高電壓驅動器618中之較少的高電壓驅動器電路。每一面板列輸入622可驅動觸摸式感測器面板624中之一或多個驅動線。在一些實施例中,高電壓驅動器618及解碼器620可整合至單個ASIC中。然而在其它實施例中,高電壓驅動器618及解碼器620可整合至驅動器邏輯614中,且在又一些實施例中,可完全去除高電壓驅動器618及解碼器620。
計算系統600亦可包含主機處理器628以用於接收來自面板處理器602之輸出並基於所述輸出執行動作,所述動作可包含(但不限於)移動諸如游標或指針之物件、捲動或平移、調節控制設定、打開檔案或文件、觀看選單、做出選擇、執行指令、操作連接至主機裝置之周邊裝置、接電話、打電話、掛電話、改變音量或音訊設定、儲存諸如地址、常撥號碼、來電、未接來電之關於電話通信之資訊、登錄電腦或電腦網路、許可經授權個人存取電腦或電腦網絡之受限區域、載入與使用者偏好之電腦桌面配置相關聯之使用者設定檔、許可存取網路內容、開始特定程式、加密或解碼訊息,及/或類似動作。主機處理器628亦可執行可能與面板處理無關之額外功能,且可耦接至程式儲存裝置632及諸如LCD之顯示裝置640以用於向裝置使用者提供使用者介面(UI)。
上述觸摸式感測器面板可有利地用於圖6之系統中以提供較低成本、較易製造且配合於現有機械控制輪廓(相同實體包絡)的空間高效的觸摸式感測器面板及UI。
圖7a說明根據本發明實施例之可包含觸摸式感測器面板724及顯示裝置730堆疊(視需要使用PSA 734結合在一起)及上述計算系統的例示性行動電話736。圖7b說明根據本發明實施例之可包含觸摸式感測器面板724及顯示裝置730堆疊(視需要使用PSA 734結合在一起)及上述計算系統的例示性數位音訊/視訊播放器740。圖7a及7b之行動電話
及數位音訊/視訊播放器可有利地得益於上述觸摸式感測器面板,因為觸摸式感測器面板可使此等裝置能夠更小且更便宜,此為可對消費者期望及商業成功具有顯著影響之重要消費者因素。
儘管已參看附圖完全描述本發明之實施例,但應注意熟習此項技術者將瞭解各種改變及修改。此類改變及修改應理解為包含於由附加申請專利範圍界定之本發明實施例之範疇內。
