200915163 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種觸摸感應之輸入裝置，特別是關於 用互電容作爲感應器件之觸摸輸入裝置。 【先前技術】 觸控板是現在被廣泛應用的一種觸摸傳感輸入裝置。 按照觸摸感應原理，現有技術觸控板包括電阻式觸控板、 電容式觸控板、表面紅外觸控板等等。其中，電阻式觸控 板因爲其低成本、易實現、控制簡單等優點流行多年。近 來，電容式觸控板以其透光率高、耐磨損、耐環境溫度變 化、耐環境濕度變化、壽命長、可實現如多點觸摸的高級 複雜功能而受到大眾的歡迎。 利用電容變化作爲傳感原理由來已久，爲使觸控板有 效工作，需要一個透明的電容傳感陣列。當人體或者如手 寫筆的專用觸摸裝置接近電容的感應電極時，會改變傳感 控制電路檢測到電容值的大小，根據觸摸區域内電容值變 化的分布，就可以判斷出人體或者專用觸摸裝置在觸摸區 域内的觸摸情况。按照電容形成的方式，現有技術觸控板 包括自電容式觸控板和互電容式觸控板。自電容式觸控板 是利用傳感電極與交流或直流電憑電極形成的電容值變化 作爲觸摸傳感的信號；互電容式觸控板是利用兩個電極間 形成的電容值變化作爲觸摸傳感的信號，有時也把互電容 稱爲投射電容。 5 200915163 如第11圖所示，現有技術互電容式觸控板包括觸摸平 面100’，不在同一平面的驅動線210，和傳感線310,，以及 夾在該驅動線210’和傳感線310,之間的介質平面910,。如 第11 — 1圖和第11 —2圖所示，各該驅動線210,互相平行， 各該傳感線31(V互相平行’並且該驅動線21〇，與傳感線31〇, 在空間垂直交叉。該驅動線210,電連接激勵信號，該傳感 線310’電連接傳感控制電路，從而在驅動線21〇，與傳感線 31〇f間形成互電容。在該驅動線21〇，與傳感線31〇,交叉之 處形成的互電容C是傳感控制電路檢測的主要電容數據信 號。如第11 一3圖所示，該互電容c包括驅動線21〇，與傳 感線310’底部之間的電容CB和驅動線21〇，與傳感線31〇, 頂部之間的電容心，即c=Cb + Ct。如第u —4圖所示’ 當手指150’接觸觸摸平面1〇〇,並在觸摸區域内時，該手指 150'相當於在傳感線31〇，之上的一個電極，改變了驅動線 2HV與傳感線310’頂部之間電場，這種改變可以看作手指 150'將驅動線210,到傳感線31〇,頂部的電場線吸走，從= 使CT發生變化’導致該互電容〇發生變化。該傳感控制電 路檢測觸摸平面1〇〇'整個觸摸區域内的互電容c變化情 况，以確定觸摸區域内被觸摸點的位置和强度。透過合= 設計傳感控制電路，該傳感控制電路能够同時檢 面着上發㈣多關狀分树况，實現傳❹點觸摸 功能。所述cT值的變化範圍在未發生觸摸時的互電容c中 所占比例被稱爲有效電容率。 如第11圖所示，當現有技術觸控板被觸摸時，該驅動 200915163 線2HV與傳感線310'底部之間的電容CB不受觸摸影響， 由於該傳感線310’底部與驅動線21〇，正對，使該電容匸 在互電容C中所占_較大’從而令該麵電容率較低〇B 現有技術互感式觸控板的有效電容率一般只能達到左 右，造成關控板料比低，需要設計複雜的傳感控^電 路以精確判斷人體或者專賴摸裝置以針對該觸控板的觸 摸情况，增加了該觸控板的設計和製造成本。 【發明内容】 本發明要解决的技術問題在於避免現有技術的不足之 處而提出能大幅提高有效電容率的互電容式觸控板及組合 式互電容觸控板。 本發明解决所述技術問題可以透過採用以下技術方案 來實現：

大小相同的矩形電極；或者，各該驅動電極是大小相同的 菱形電極；該傳感電極是大小相同的菱形電極；又或者， 各該驅動電極是大小相同的六邊形電極；該傳感電極是大 小相同的菱形電極。 •本發明在所述互電容式觸控板的基礎上還提出一種組 f 合式互電容觸控板，可以透過採用以下技術方案來實現： 設計、製造一種組合式互電容觸控板，包括用透明絕 緣介質製成的觸摸面板，尤其是，還包括被該觸摸面板覆

同現有技術相比較’本發明“互電容式觸控板及組合式 互電容觸控板”的技術效果在於： 該驅動電極與傳感電極空間位置不是正對關係，該驅 動電極與傳感電極底部之間形成的電容cB大幅降低，提高 了該驅動電極與傳感電極頂部之間形成的電容cT在互電 容C中所占比例，從而提咼了由觸摸傳感引起該CT的變化 在未觸摸時互電容c中的比例，有效增加了該互電容式觸 200915163 控板的有效電容率；

感電極310，該各傳感電極31〇分布在傳感層3〇〇中與驅 動層200中該各驅動電極21〇相互間空隙區域正對著的區 域内，令該驅動電極210和傳感電極310 一起填充該觸摸 平面100的觸摸區域110。該驅動電極21〇與觸控板外設 的激勵信號模塊600電連接，該傳感電極310與觸控板外 設的傳感控制模塊700電連接。 本發明互電容式觸控板的驅動電極21〇與傳感電極 310不會出現正對的情况，因此本發明在該驅動電極 與傳感電極310底部之間形成的電容Cb比現有技術該驅動 線21〇,與傳感線31〇,底部之間形成的電容Cb小，從而本發 明中該電容CB在互電容C中所占比例小，提高了本發明互 電容C的有效電容率。 本發明該互電容式觸控板的驅動電極210和傳感電極 31〇的形狀和它們在各自相應的驅動層2〇〇和傳感層3⑻ 内的連接分布情况可以多種多樣，本發明透過第施例 至第七實施例提出了幾種適於應用和實踐的形狀和連 布情况。 本發明各實施例的互電容式觸控板都採用以下的技術 方案·該互電容式觸控板還包括用透明導電材料製成的驅 動電極連接線220和傳感電極連接線320，以及驅動電極 弓^出導線230和傳感電極引出導線33Q;該驅動電極21〇 借助驅動電極連接線22G綠㈣在—起，錢驅動電極 12 200915163 連接線220在驅動層200内的相互之間的位置關係包括共 線和平行；該傳感電極310借助傳感電極連接線32〇分組 串聯在一起’各該傳感電極連接線320在傳感層3〇〇二相 互之間的位置關係包括共線和平行；該驅動電極連接線22〇 與傳感電極連接線320互相垂直；各驅動電極組24〇借助 驅動電極引出線230與觸控板外設的激勵信號模塊6〇〇電 連接，各傳感電極組340借助傳感電極引出線與觸控 板外設的傳感控制模塊700電連接。如第i圖至第7圖所 示，本發明各實施例驅動電極連接線22〇和傳感電極連接 線320各自的位置關係既有共線也有平行，即該驅動電極 組240中的各驅動電極21〇的幾何中心與各驅動電極連接 線220在同一直線上，該驅動電極組24〇各自的驅動電極 連接線220所在的直線互相平行；該傳感電極組34〇中的 各傳感電極310的幾何中心和各傳感電極連接線32〇在同 一直線上，該傳感電極組34〇各自的傳感電極連接線32〇 所在的直線互相平行；也就是，對於驅動層2〇〇内的驅動 電極連接線220和在傳感層3〇〇内的傳感電極連接線32〇, 在電極組内的電極連接線的位置關係是共線，電極組之間 的電極連接線的位置關係是平行的。 本發明第一實施例，如第i圖所示，各該驅動電極21〇 是矩形驅動電極211 ’在本實施例中有25個矩形驅動電極 2Π，各該傳感電極31〇是矩形傳感電極311，在本實施例 中有36個矩形傳感電極3丨i。 如第1一 1圖所示，該矩形傳感電極311透過傳感電極 13 200915163 連接線320被分組串聯成6組傳感電極組340，每組傳感 電極組340中的各矩形傳感電極311的幾何中心和各矩形 傳感電極310連接線320在同一直線上，而且各傳感電極 組340内的傳感電極連接線320所在的直線互相平行。各 傳感電極組340借助傳感電極引出線330與觸控板外設的 傳感控制模塊700電連接。 如第1 — 2圖所示，該矩形驅動電極211透過驅動電極 連接線220被分組串聯成5組驅動電極組240，每組驅動 電極組240中的各矩形驅動電極211的幾何中心和各驅動 電極連接線220在同一直線上，而且各驅動電極組240内 的驅動電極連接線220所在的直線互相平行。各驅動電極 組240借助驅動電極引出線23〇與觸控板外設的激勵信號 模塊600電連接。 如第1 — 3圖所示’各該矩形傳感電極3u分布在傳感 層j00中與驅動層200中各該矩形驅動電極211相互間空 隙區域正對著的區域内，令該矩形驅動電極211和傳感電 極311 一起填充該觸控板的觸摸區域110。該驅動電極連接 線220與傳感電極連接線32〇互相垂直。 ▲如第1-3圖和第丨_4圖所示，在整個觸摸區域11〇 ^ °亥矩形傳感電極311所占區域與矩形驅動電極211所占 區域互補，使矩形傳感電極311與矩形驅動電極Μ〗不會 出現正對的位置關係。 上對於第1 — 4圖所示的〇1點，當沒有對〇1點觸摸時， 〇1點的電場分布情况如第1 — 5圖所示；當手指150對 200915163 (^點觸摸時，該〇1點的電場分布情况如第1 — 6圖所示。 由於矩形傳感電極311底部沒有正對矩形驅動電極211，所 以矩形傳感電極311底部與矩形驅動電極211之間形成的 電容CB的電容值相對現有技術有大幅减小，即該矩形傳感 電極311底部與矩形驅動電極211之間形成的電容cB在 〇ι點的互電容C中所占比例大幅减小，從而有效提高了互 電容式觸控板的互電容C的有效電容率。 本發明第二實施例，如第2圖所示，該驅動層200和 傳感層300與第一實施例完全相同，只是加入了屏蔽層 4〇〇。該屏蔽層400設置於驅動層200和傳感層300中位於 下方的—層的上方、下方或者嵌套在該層内；該屏蔽層400 包括用透明導電材料製成的平板屏蔽電極410,各該屏蔽 電極410正對著該驅動層2〇〇和傳感層3〇〇中位於上方的 一層中各電極所占區域。 在本實施例中，該傳感層3〇〇位於驅動層2〇〇的上方， 因此如第2—1圖所示，各該屏蔽電極41〇分布在屏蔽層 400中正對著該傳感層3GG中各傳感電極310所占的區域， 並且被連接成6個屏蔽電極410，換㈣度說，該屏蔽電 極410分布在屏蔽層4〇〇中與驅動層2〇〇的各驅動電極 相互之間的空隙區域正對著的區域。 如第2-2圖所示，該屏蔽電極41〇所占區域與矩形驅 動電極211互補，本實施例中，將屏蔽層4〇〇與驅動層2⑻ 嵌套在-起，如第2 —3圖所示，即屏蔽層與驅 200在同一層中。 15 200915163 對於第2—3圖所示的〇2點，當沒有對〇2點觸摸時， 該〇2點的電場分布情况如第2_4圖所示；當手指15〇對 〇2點觸摸時，該〇2點的電場分布情况如第2—5圖所示。 由第2 —4圖和第2-5圖可見，該屏蔽電極410的作用在 於改變矩形傳感電極311底部的電場，使矩形傳感電極311 底部與矩形驅動電極211之間形成的電容cB進一步减小， 這可以理解爲’屏蔽電極410將矩形驅動電極211與矩形 傳感電極311底部電場中的部分電場線吸走。 該屏蔽電極410可以是電懸空的，即不與互電容式觸 控板外設的任何激勵信號、交流地和直流源電連接，也可 以採用如下的方案：如第3圖所示，該屏蔽層400還包括 屏蔽電極引出導線430，借助該屏蔽電極引出導線43〇，所 有屏蔽電極410接地’或者與觸控板外設的直流源8〇〇電 連接。另外，爲减少該屏蔽電極引出導線430的數量，一 般用一條或者兩條屏蔽電極引出導線43G把所有的屏蔽電 電連接至錢源_，或者直賴交流地；同時儘 Ϊ避免屏蔽電極引出導線與驅動電極引出導線⑽和 傳感電極引出導線33()交叉。對於本發明第二實施例，第 3圖顯不出了四種情况以體現四種屏蔽電極引出線物的 引出隋况’其中，第圖和第3 —2圖示出用兩條屏蔽 電=引出導線將所有屏蔽電極41G電連接交流地或者 、 圖和第3 —4圖顯示出用一條屏蔽電 極引出導線43G將所有屏蔽電極41()電連接交流地。對於 本發明其它具有屏蔽層_的實施例 ，該屏蔽電極410接 16 200915163 地或者與觸控板外設的直流源800電連接方式可以採用第 4圖所示的任何一種’也可以採用其它一切使該屏蔽電極 引出線430與驅動電極引出線230在空間互不相交的其它 方式。 本發明第三實施例，如第4圖所示，該驅動層2〇〇和 傳感層300與第一實施例完全相同’只是加入了次電極層 500。該次電極層500設置於驅動層200和傳感層3〇〇中位 於上方的一層的上方、下方或者嵌套在該層内；該次電極 〔層500包括用透明導電材料製成的平板次電極510，各該 次電極510正對著該驅動層200和傳感層300中位於下方 的一層中各電極所占區域。 本實施例該驅動層200位於傳感層300的下方，因此， 如第4 — 1圖所示’各該次電極510正對著該驅動層200中 各電極所占區域’換個角度說，該次電極510分布在次電 極層500中與該驅動層200各驅動電極21〇所占區域正對 著的區域内。在次電極層500中正對著驅動層200的某個 驅動電極210的區域内，可以分布多個填滿該區域次電極 510 ’也可以僅用一個次電極510 ;本實施例中，在次電極 層500中每個與驅動電極210正對著的區域内就緊密排布 了 16個面積較小的次電極510，這種結構可以使電場分布 更加均勻，有利於觸摸傳感。各該次電極510互不連接， 而且不像普通的電極與任何信號激勵源、直流源或者地線 電連接，處於電懸空狀態，因此被稱爲次電極或者虛擬電 池(Dummy Cell) 0 17 200915163 如第4一 2圖所示，該次電極410所占區域與矩形傳感 電極311互補，本實施例中，將次電極層500與傳感層300 嵌套在一起，如圖4—3所示，即次電極層500與傳感層 300在同一層中。 對於第4—3圖所示的03點，當沒有對03點觸摸時， 該03點的電場分布情况如第4 —4圖所示；當手指150對 〇3點觸摸時，該〇3點的電場分布情况如第5 —5圖所示。 由第4 —4圖和第4—5圖可見，該次電極510的作用在於 改變矩形傳感電極311頂部的電場，使矩形傳感電極311 頂部與矩形驅動電極211之間形成的電容CT進一步增大， 以增加CT的變化範圍。這可以理解爲，該次電極510增 加矩形驅動電極211與矩形傳感電極311頂部電場中的電 場線；另外，該次電極510的作用還在於使觸控板的透光 率趨於一致。 本發明第四實施例，如第5圖所示，該驅動層200和 傳感層300與第一實施例完全相同，只是加入了與第二實 施例相同的屏蔽層400和與第三實施例相同的次電極層 500。 如第5— 1圖所示，該屏蔽層400與驅動層200嵌套在 一起，該次電極層500與傳感層300嵌套在一起。 對於第5 - 1圖所示的04點，當沒有對04點觸摸時， 該04點的電場分布情况如第5 —2圖所示；當手指150對 〇4點觸摸時，該〇4點的電場分布情况如第5-3圖所示。 由第6 —2圖和第5 —3圖可見，在該屏蔽電極410和次電 18 200915163 極510的共同作用下’使矩形傳感電極311底部與矩形驅 動電極211之間形成的電容cB進一步减小，使矩形傳感電 極311頂部與矩形驅動電極211之間形成的電容&進一步 增大，從而進一步提高互電容C的有效電容率。 本發明第五實施例’如第6圖所示，該互電容式觸控 板包括驅動層200、傳感層300、屏蔽層400和次電極層 500。 如第6-1圖所示’該驅動層200包括驅動電極210， 而且各驅動電極210是菱形驅動電極212，本實施例設置 了 25個菱形驅動電極212。該菱形驅動電極212透過驅動 電極連接線220被分組串聯成5組驅動電極組240，每組 驅動電極組240中的各菱形驅動電極212的幾何中心和各 驅動電極連接線220在同一直線上，而且各驅動電極組240 内的驅動電極連接線220所在的直線互相平行。各驅動電 極組240與觸控板外設的激勵信號模塊6〇〇電連接的情况 如同第一實施例。 如第6—2圖所示，該驅動層3〇〇包括傳感電極310 ’ 而且各傳感電極310是菱形傳感電極312，本實施例設置 了 36個菱形傳感電極312。該菱形傳感電極312透過傳感 電極連接線320被分組串聯成6組傳感電極組 340，每組 傳感電極組340中的各菱形傳感電極312的幾何中心和各 菱形傳感電極連接線320在同一直線上，而且各傳感電極

Field of the Invention The present invention relates to a touch-sensing input device, and more particularly to a touch input device using a mutual capacitance as an inductive device. [Prior Art] A touch panel is a touch sensing input device that is now widely used. According to the principle of touch sensing, the prior art touch panel includes a resistive touch panel, a capacitive touch panel, a surface infrared touch panel, and the like. Among them, the resistive touch panel has been popular for many years because of its low cost, easy implementation, and simple control. Recently, capacitive touch panels have been popularly popular for their high light transmittance, wear resistance, environmental temperature change, environmental humidity resistance, long life, and advanced complex functions such as multi-touch. The use of capacitive changes as a sensing principle has been around for a long time. In order for the touchpad to work effectively, a transparent capacitive sensing array is required. When the human body or a special touch device such as a stylus approaches the sensing electrode of the capacitor, the magnitude of the capacitance value detected by the sensing control circuit is changed, and according to the distribution of the capacitance value change in the touch region, it can be determined that the human body or the dedicated touch device is Touch the touch in the area. According to the manner in which the capacitor is formed, the prior art touch panel includes a self-capacitive touch panel and a mutual capacitive touch panel. The self-capacitive touch panel utilizes a change in capacitance value formed by the sensing electrode and the alternating current or direct current electrode as a touch sensing signal; the mutual capacitive touch panel utilizes a change in capacitance value formed between the two electrodes as a touch sensing The signal is sometimes referred to as a projected capacitor. 5 200915163 As shown in FIG. 11, the prior art mutual capacitive touch panel includes a touch plane 100', a driving line 210 not in the same plane, and a sensing line 310, and is sandwiched between the driving line 210' and the sensing line 310, between the media plane 910,.

As shown in FIG. 11-3, the mutual capacitance c includes the driving line 21〇, and The capacitance CB between the bottom of the sensing line 310' and the driving line 21A, and the sensing line 31〇, the capacitance between the top, ie c=Cb + Ct. As shown in Figure u-4, when the finger 150 'When the touch plane is touched, and in the touch area, the finger 150' corresponds to an electrode above the sensing line 31A, changing the electric field between the driving line 2HV and the top of the sensing line 310', This change can be seen as the finger 150' will drive the line 210, to the sense line 31〇, the top electric field line is sucked away, and the change from CT = The mutual capacitance 〇 changes. The sensing control circuit detects the change of the mutual capacitance c in the entire touch area of the touch plane 1′′ to determine the position and intensity of the touched point in the touch area. The sensing control circuit can simultaneously detect the top (four) multi-gate sub-tree conditions, and realize the transmission point touch function. The proportion of the cT value change range in the mutual capacitance c when no touch occurs is called For the effective permittivity, as shown in FIG. 11, when the prior art touch panel is touched, the capacitance CB between the drive 200915163 line 2HV and the bottom of the sense line 310' is not affected by the touch, since the sense line 310 'Bottom and drive line 21〇, facing, so that the capacitor 占 _ _ in the mutual capacitance C 从而 从而 令 该 该 该 该 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有 现有To achieve the left and right, resulting in a low ratio of the control panel, it is necessary to design a complex sensing control circuit to accurately determine the human body or the device to touch the touch panel, increasing the design and manufacturing cost of the touch panel.
