本發明係關於一種互電容式觸控裝置，尤指一種利用各子電極與對應電極之間的距離差異來達到減少走線數量之互電容式觸控裝置。The present invention relates to a mutual capacitive touch device, and more particularly to a mutual capacitive touch device that utilizes a difference in distance between each sub-electrode and a corresponding electrode to reduce the number of traces.
觸控面板由於具有人機互動的特性，已被廣泛應用於儀器的外埠輸入介面上。近年來，隨著消費性電子產品的應用面發展越來越廣，將觸控功能與顯示器結合而形成觸控顯示面板之應用產品也越來越多，包括行動電話(mobile phone)、衛星導航系統(GPS navigator system)、平板電腦(tablet PC)、個人數位助理(PDA)以及筆記型電腦(laptop PC)等。Touch panels have been widely used in the external input interface of instruments due to their human-computer interaction. In recent years, as the application of consumer electronic products has become more and more widespread, more and more applications have been made to combine touch functions with displays to form touch display panels, including mobile phones and satellite navigation. GPS navigator system, tablet PC, personal digital assistant (PDA), and laptop PC.
目前觸控面板的技術發展非常多樣化，較常見的技術包括電阻式、電容式以及光學式等。其中電容式觸控面板由於具有高準確率、多點觸控、高耐用性以及高觸控解析度等特點，已成為目前中高階消費性電子產品使用之主流觸控技術。如第1圖所示，習知之互電容式觸控面板100具有一觸控訊號驅動電極110以及與其對應設置之複數個觸控訊號接收電極120。觸控訊號接收電極120係沿觸控訊號驅動電極110之延伸方向排列設置且彼此電性絕緣，各觸控訊號接收電極120需藉由一走線120T與其連接用以將接收到的觸控訊號傳遞至訊號處理元件(未圖式)來進行觸控點的計算。在習知之互電容式觸控面板100中，為了增加觸控解析度必須增加觸控訊號接收電極120以及對應之走線120T的設置數量。然而，走線120T的數量增加會導致走線120T所佔據的區域變大，不利於整體的線路佈局設計以及窄邊框的設計趨勢。At present, the technology development of touch panels is very diverse, and the more common technologies include resistive, capacitive, and optical. Among them, capacitive touch panels have become the mainstream touch technology used in middle and high-end consumer electronic products due to their high accuracy, multi-touch, high durability and high touch resolution. As shown in FIG. 1 , the conventional mutual capacitive touch panel 100 has a touch signal driving electrode 110 and a plurality of touch signal receiving electrodes 120 corresponding thereto. The touch receiving electrodes 120 are arranged along the extending direction of the touch driving electrodes 110 and electrically insulated from each other. The touch receiving electrodes 120 are connected to the touch signals by a trace 120T for receiving the received touch signals. Pass to the signal processing component (not shown) to calculate the touch point. In the conventional mutual capacitive touch panel 100, in order to increase the touch resolution, the number of the touch signal receiving electrodes 120 and the corresponding traces 120T must be increased. However, an increase in the number of traces 120T may result in a larger area occupied by the trace 120T, which is disadvantageous for the overall layout design and the design trend of the narrow bezel.

為使熟習本發明所屬技術領域之一般技藝者能更進一步了解本發明，下文特列舉本發明之數個較佳實施例，並配合所附圖式，詳細說明本發明的構成內容。The present invention will be described in detail with reference to the preferred embodiments of the invention,
如第2圖至第6圖所示，本發明第一實施例之互電容式觸控裝置201包括一基板210以及一觸控元件220。基板210可包括一玻璃基板(厚度可介於0.1毫米至2毫米)、一塑膠基板(厚度可介於0.003毫米至2毫米)、一藍寶石基板、一透明陶瓷基板、其他適合之基板或上述基板之複合疊層。前述的玻璃基板與塑膠基板可以當作覆蓋板或顯示器的基板。例如顯示器的基板可為一液晶顯示器的彩色濾光基板或一有機發光顯示器的封裝蓋，但並不以此為限。塑膠基板的材料可以例如是聚對苯二甲酸乙二酯(Polyethylene terephthalate,PET)、聚丙烯(polypropylene,PP)、聚乙烯(polyethylene,PE)、聚碳酸酯(polycarbonate,PC)、聚甲基丙烯酸甲酯(methyl methacrylate,PMMA)、聚亞醯胺(Polyimide,PI)、聚環烯烴聚合物(Cyclo olefin polymer,COP)。塑膠基板可以是單層材質的基板或是兩層以上不同材質堆疊而成的基板。例如當塑膠基板是當作覆蓋板使用時，可以是採用PMMA與PC雙層材質堆疊而成。當覆蓋板是玻璃基板時，此玻璃基板可以是經過化學或是物理強化的強化玻璃，因此可具有高機械強度，以保護觸控元件220與所搭配的顯示器，且覆蓋板的厚度可介於0.25毫米至2毫米之間。藍寶石基板與透明陶瓷基板也可以當作覆蓋板使用，且厚度可介於0.1毫米至2毫米之間。其中，覆蓋板為提供使用者觸摸之基板，但也可能透過其他膜層提供使用者觸摸，例如：抗反射材料層、抗污材料層、抗眩材料層等單一膜層或堆疊膜層。As shown in FIG. 2 to FIG. 6 , the mutual capacitive touch device 201 of the first embodiment of the present invention includes a substrate 210 and a touch element 220 . The substrate 210 may include a glass substrate (thickness may be between 0.1 mm and 2 mm), a plastic substrate (thickness may be between 0.003 mm and 2 mm), a sapphire substrate, a transparent ceramic substrate, other suitable substrates or the above substrates. Composite laminate. The aforementioned glass substrate and plastic substrate can be used as a substrate for a cover plate or a display. For example, the substrate of the display may be a color filter substrate of a liquid crystal display or a package cover of an organic light emitting display, but is not limited thereto. The material of the plastic substrate may be, for example, polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), polycarbonate (PC), polymethyl. Methyl methacrylate (PMMA), polyimide (PI), Cycloolefin polymer (COP). The plastic substrate may be a single-layer substrate or a substrate in which two or more layers of different materials are stacked. For example, when the plastic substrate is used as a cover plate, it may be formed by stacking PMMA and PC double-layer materials. When the cover plate is a glass substrate, the glass substrate may be a chemically or physically strengthened tempered glass, so that the glass substrate can have high mechanical strength to protect the touch element 220 and the matched display, and the thickness of the cover plate can be between Between 0.25 mm and 2 mm. The sapphire substrate and the transparent ceramic substrate can also be used as a cover sheet and can have a thickness of between 0.1 mm and 2 mm. Wherein, the cover plate is a substrate for providing a user's touch, but it is also possible to provide a user's touch through other film layers, for example, a single film layer or a stacked film layer such as an anti-reflective material layer, an anti-fouling material layer, and an anti-glare material layer.
觸控元件220係設置於基板210上，且觸控元件220包括至少一第一電極221以及至少一第二電極222。本實施例之互電容式觸控裝置201可更包括一透光區R1、一周圍區R2、至少一第一走線221T以及至少一第二走線222T。周圍區R2係位於透光區R1之至少一側，而本實施例之周圍區R2係圍繞透光區R1，但並不此為限。第一走線221T係與第一電極221電性連接，且第二走線222T係與第二電極222電性連接。第一電極221與第二電極222係至少部分設置於透光區R1中，且第一走線221T與第二走線222T係至少部分設置於周圍區R2中。第二電極222係與第一電極221於一第一方向X上相鄰設置。第二電極222包括複數個子電極S沿一第二方向Y排列且彼此電性連接。在本實施例中，第一方向X大體上係與第二方向Y正交，但並不以此為限。第一電極221與第二電極222其中至少一者為一觸控訊號驅動電極或一觸控訊號接收電極，藉此進行搭配以實現互電容式觸控操作。舉例來說，本實施例之第一電極221較佳係為一觸控訊號驅動電極，而第二電極222較佳係為一觸控訊號接收電極，但並不以此為限。在本發明之其他實施例中，第一電極221亦可視需要為一觸控訊號接收電極用以與作為觸控訊號驅動電極之第二電極222進行搭配。在本實施例中，第一電極221較佳係為一條狀電極沿第二方向Y延伸，第二電極222之各子電極S於第一方向X上與第一電極221之間的間距D係彼此相異，藉此使得各子電極S與第一電極221之間所形成的電容效應彼此相異。當操作者觸碰第二電極222中不同子電極S時其所造成之電容變化量亦會有所不同，故可藉此分辨出第二電極222中於第二方向Y上被觸碰的不同位置。然而，本發明之第二電極222卻只需單一條第二走線222T進行觸控訊號的傳遞，故在相同的觸控解析度的狀況下，本發明之互電容式觸控裝置201可達到減少所需走線數目的效果，對於觸控裝置中的線路佈局設計以及窄邊框的設計趨勢都有正面的幫助。The touch component 220 is disposed on the substrate 210 , and the touch component 220 includes at least one first electrode 221 and at least one second electrode 222 . The mutual capacitive touch device 201 of this embodimentThe light transmissive region R1, the surrounding region R2, the at least one first trace 221T, and the at least one second trace 222T may be further included. The peripheral region R2 is located on at least one side of the light-transmitting region R1, and the peripheral region R2 of the present embodiment surrounds the light-transmitting region R1, but is not limited thereto. The first trace 221T is electrically connected to the first electrode 221 , and the second trace 222T is electrically connected to the second electrode 222 . The first electrode 221 and the second electrode 222 are at least partially disposed in the light-transmitting region R1, and the first trace 221T and the second trace 222T are at least partially disposed in the peripheral region R2. The second electrode 222 is disposed adjacent to the first electrode 221 in a first direction X. The second electrode 222 includes a plurality of sub-electrodes S arranged along a second direction Y and electrically connected to each other. In this embodiment, the first direction X is substantially orthogonal to the second direction Y, but is not limited thereto. At least one of the first electrode 221 and the second electrode 222 is a touch signal driving electrode or a touch signal receiving electrode, thereby performing a mutual capacitive touch operation. For example, the first electrode 221 of the present embodiment is preferably a touch signal driving electrode, and the second electrode 222 is preferably a touch signal receiving electrode, but is not limited thereto. In other embodiments of the present invention, the first electrode 221 can also be a touch signal receiving electrode for collocation with the second electrode 222 as the touch signal driving electrode. In this embodiment, the first electrode 221 is preferably a strip electrode extending in the second direction Y, and the distance D between the sub-electrodes S of the second electrode 222 in the first direction X and the first electrode 221 is They are different from each other, whereby the capacitive effects formed between the respective sub-electrodes S and the first electrodes 221 are different from each other. When the operator touches the different sub-electrodes S in the second electrode 222, the amount of capacitance change caused by the second electrode 222 is also different, so that the difference in the second electrode 222 being touched in the second direction Y can be distinguished by this. position. However, the second electrode 222 of the present invention only needs a single second trace 222T for the transmission of the touch signal, so that the mutual capacitive touch device 201 of the present invention can be achieved under the same touch resolution. The effect of reducing the number of traces required has a positive impact on the layout design of the touch device and the design trend of the narrow bezel.
更進一步舉例說明，本實施例之各第二電極222之子電極S可包括一第一子電極S1、一第二子電極S2以及一第三子電極S3沿第二方向Y排列且彼此電性連接，但子電極S的數量並不以此為限。第一子電極S1與第一電極221之間具有一第一間距D1，第二子電極S2與第一電極221之間具有一第二間距D2，且第三子電極S3與第一電極221之間具有一第三間距D3。當第一間距D1大於第二間距D2，且第二間距D2大於第三間距D3時，操作者觸碰第一子電極S1與第一電極221之間的第一觸碰區TR1所造成的電容變化量會大於觸碰第二子電極S2與第一電極221之間的第二觸碰區TR2所造成的電容變化量，且操作者觸碰第二子電極S2與第一電極221之間的第二觸碰區TR2所造成的電容變化量會大於觸碰第三子電極S3與第一電極221之間的第三觸碰區TR3所造成的電容變化量(其關係趨勢如同第6圖所示)。更進一步說明，如第3圖至第5圖所示，當第二電極222之各子電極S於第一方向X上與第一電極221之間的間距D變大時，子電極S與第一電極221之間所形成之電力線EL的範圍亦會隨之擴大。相對地，當操作者所觸碰之觸碰區具有較大範圍之電力線EL分布時，因觸碰所造成之電容變化量也會較為顯著。因此，可利用對應於第二電極222之單一條第二走線222T所接收到的電容變化量狀況來分辨第一觸碰區TR1、第二觸碰區TR2或第三觸碰區TR3何者被觸碰。值得說明的是，本發明之第二電極222所具有之子電極S的數量並不以上述狀況為限而可視設計需要進行調整。舉例來說，當同一個第二電極222中有複數個觸碰區被觸碰時，可藉由演算法計算分析電容變化量來達到於同一第二電極222中實現多點觸控判讀的效果。因此，各第二電極222中的子電極S之數量亦可配合演算法而有所調整與限制。Further, the sub-electrode S of each of the second electrodes 222 of the present embodiment may include a first sub-electrode S1, a second sub-electrode S2, and a third sub-electrode S3 arranged in the second direction Y and electrically connected to each other. However, the number of sub-electrodes S is not limited thereto. The first sub-electrode S1 and the first electrode 221 have a first interval D1, and the second sub-electrode S2 and the first electrode 221 haveA second pitch D2, and a third pitch D3 between the third sub-electrode S3 and the first electrode 221. When the first pitch D1 is greater than the second pitch D2, and the second pitch D2 is greater than the third pitch D3, the capacitance of the first touch region TR1 between the first sub-electrode S1 and the first electrode 221 is touched by the operator. The amount of change may be greater than the amount of change in capacitance caused by touching the second touch region TR2 between the second sub-electrode S2 and the first electrode 221, and the operator touches between the second sub-electrode S2 and the first electrode 221 The amount of change in capacitance caused by the second touch area TR2 is greater than the amount of change in capacitance caused by touching the third touch area TR3 between the third sub-electrode S3 and the first electrode 221 (the relationship is similar to that shown in FIG. Show). Further, as shown in FIGS. 3 to 5, when the pitch D between the sub-electrodes S of the second electrode 222 in the first direction X and the first electrode 221 becomes larger, the sub-electrode S and the The range of the power line EL formed between the electrodes 221 also increases. In contrast, when the touch area touched by the operator has a large range of power line EL distribution, the amount of capacitance change caused by the touch is also significant. Therefore, the first touch region TR1, the second touch region TR2 or the third touch region TR3 can be distinguished by the capacitance change amount condition received by the single second trace 222T corresponding to the second electrode 222. Touch. It should be noted that the number of the sub-electrodes S of the second electrode 222 of the present invention is not limited to the above conditions, and the visual design needs to be adjusted. For example, when a plurality of touch regions are touched in the same second electrode 222, the effect of multi-touch interpretation in the same second electrode 222 can be achieved by calculating an analytical capacitance change amount by an algorithm. . Therefore, the number of sub-electrodes S in each of the second electrodes 222 can also be adjusted and limited according to an algorithm.

如第9圖與第10圖所示，本發明之第四實施例提供一互電容式觸控裝置204。與上述第一實施例不同的地方在於，本實施例之各第二電極222更包括至少一連接線222C設置於第二方向Y上兩相鄰之子電極S之間，用以電性連接子電極S。連接線222C之電阻值較佳係大於各子電極S之電阻值，藉此可利用連接線222C所造成之線阻抗差異來輔助同一第二電極222中被觸碰位置之判讀。舉例來說，本實施例之各第二電極222可包括六個子電極S，分別為第一子電極S1、第二子電極S2、第三子電極S3、第四子電極S5、第五子電極S5以及第六子電極S6沿第二方向Y上依序排列設置，而各第二電極222可包括五個連接線222C分別設置於第二方向Y上兩相鄰之子電極S之間。同一個第二電極222中的各子電極S於第一方向X上與第一電極221之間的間距D係彼此相異，藉此使得各子電極S與第一電極221之間所形成的電容效應彼此相異，而可如上述第一實施例中用來進行電容式觸控偵測的判讀。此外，當第二走線222T係直接連接於第二電極222的一端(如第9圖中直接連接於第六子電極S6)時，操作者觸碰不同子電極S之間的觸碰點時利用第二走線222T所讀取到對於第二電極222的充放電時間差異，可計算出其線阻抗大小，進而可計算出觸碰點的位置。更明確地說，如第9圖與第10圖所示，當操作者觸碰第一子電極S1與第二子電極S2之間的第一觸碰點T1時，其對應之線阻抗包括約五個連接線222C串聯之電阻抗；當操作者觸碰第二子電極S2與第三子電極S3之間的第二觸碰點T2時，其對應之線阻抗包括約四個連接線222C串聯之電阻抗；當操作者觸碰第三子電極S3與第四子電極S4之間的第三觸碰點T3時，其對應之線阻抗包括約三個連接線222C串聯之電阻抗；當操作者觸碰第四子電極S4與第五子電極S5之間的第四觸碰點T4時，其對應之線阻抗包括約兩個連接線222C串聯之電阻抗；當操作者觸碰第五子電極S5與第六子電極S6之間的第五觸碰點T5時，其對應之線阻抗包括約一個連接線222C之電阻抗。因此，第一觸碰點T1至第五觸碰點T5的線阻抗會呈現遞減的趨勢，而可藉由此線阻抗差異之計算(其關係趨勢如同第10圖所示)來輔助同一第二電極222中被觸碰位置之判讀。As shown in FIG. 9 and FIG. 10, a fourth embodiment of the present invention provides a mutual capacitive touch device 204. The second electrode 222 of the present embodiment further includes at least one connecting line 222C disposed between the two adjacent sub-electrodes S in the second direction Y for electrically connecting the sub-electrodes. S. The resistance value of the connection line 222C is preferably greater than the resistance value of each sub-electrode S, whereby the difference in line impedance caused by the connection line 222C can be utilized to assist in the interpretation of the touched position in the same second electrode 222. For example, each of the second electrodes 222 of the embodiment may include six sub-electrodes S, which are a first sub-electrode S1, a second sub-electrode S2, a third sub-electrode S3, a fourth sub-electrode S5, and a fifth sub-electrode, respectively. S5 and the sixth sub-electrode S6 are arranged in the second direction Y in sequence, and each of the second electrodes 222 may include five connection lines 222C respectively disposed between the two adjacent sub-electrodes S in the second direction Y. The spacing D between the sub-electrodes S in the first second electrode 222 and the first electrode 221 in the first direction X are different from each other, thereby forming a space formed between each sub-electrode S and the first electrode 221 The capacitive effects are different from each other, and can be used for the interpretation of capacitive touch detection as in the first embodiment described above. In addition, when the second trace 222T is directly connected to one end of the second electrode 222 (directly connected to the sixth sub-electrode S6 in FIG. 9), when the operator touches the touch point between the different sub-electrodes S By using the second trace 222T to read the difference in charge and discharge time for the second electrode 222, the magnitude of the line impedance can be calculated, and the position of the touch point can be calculated. More specifically, as shown in FIGS. 9 and 10, when the operator touches the first touch point T1 between the first sub-electrode S1 and the second sub-electrode S2, the corresponding line impedance includes The electrical impedance of the five connecting wires 222C connected in series; when the operator touches the second touch point T2 between the second sub-electrode S2 and the third sub-electrode S3, the corresponding line impedance includes about four connecting lines 222C connected in series When the operator touches the third touch point T3 between the third sub-electrode S3 and the fourth sub-electrode S4, the corresponding line impedance includes an electrical impedance of about three connecting lines 222C connected in series; When the fourth touch point T4 between the fourth sub-electrode S4 and the fifth sub-electrode S5 is touched, the corresponding line impedance includes the electrical impedance of the two connecting lines 222C connected in series; when the operator touches the fifth sub- When the fifth touch point T5 between the electrode S5 and the sixth sub-electrode S6, the corresponding line impedance includes the electrical impedance of about one connection line 222C. Therefore, the first touch point T1 to the fifthThe line impedance of the touch point T5 tends to decrease, and the calculation of the touch position of the same second electrode 222 can be assisted by the calculation of the line impedance difference (the relationship trend is as shown in FIG. 10).

The difference from the first embodiment is that at least part of the first electrodes 221 of the embodiment are arranged along the second direction Y, and at least part of the second electrodes 222 are arranged along the second direction Y, and each of the first electrodes One electrode 221 is provided only corresponding to one second electrode 222. Therefore, the first electrode 221 of the present embodiment can also be a touch signal receiving electrode for performing mutual capacitive touch detection on the second electrode 222 as the touch signal driving electrode.
如第12圖所示，本發明之第六實施例提供一互電容式觸控裝置206。與上述第五實施例不同的地方在於，本實施例中至少部分於第二方向Y上相鄰設置之第二電極222係彼此電性連接。在此狀況下，第一電極221較佳係為一觸控訊號接收電極，而第二電極222較佳係為一觸控訊號驅動電極，藉以互相搭配來進行互電容式觸控偵測。各電性連接之第二電極222可通過一第二連接線223互相連接，但本發明並不以此為限。在本發明之其他實施例中亦可使第二方向Y上相鄰設置之第二電極222彼此直接相連而一體成型。As shown in FIG. 12, a sixth embodiment of the present invention provides a mutual capacitive touch device 206.

如第13圖所示，本發明之第七實施例提供一互電容式觸控裝置207。與上述第五實施例不同的地方在於，各第二電極222係為一三角型電極，藉此使得各第二電極222中的各子電極S與第一電極221之間所形成的電容效應彼此相異，用以達到減少所需第二走線222T數量之目的。As shown in FIG. 13, a seventh embodiment of the present invention provides a mutual capacitive touch device 207. The difference from the fifth embodiment is that each of the second electrodes 222 is a triangular electrode, whereby the capacitive effects formed between the respective sub-electrodes S and the first electrodes 221 of the second electrodes 222 are mutually Different, to achieve the purpose of reducing the number of second traces 222T required.
如第14圖所示，本發明之第八實施例提供一互電容式觸控裝置208。與上述第一實施例不同的地方在於，本實施例中兩個第二電極222係於第一方向X上相鄰設置，且此兩相鄰之第二電極222之間未設置任一個第一電極221。此外，與兩相鄰之第二電極222對應之兩個第一電極221係分別設置於兩相鄰之第二電極222在第一方向X上的不同側。藉由將第二電極222的形狀設計成階梯狀且使兩第二電極222互相背對背地相鄰設置，可提升空間利用效率，進而可更進一步提升觸控解析度。As shown in FIG. 14, an eighth embodiment of the present invention provides a mutual capacitive touch device 208. The difference from the first embodiment is that the two second electrodes 222 are adjacently disposed in the first direction X, and no first one is disposed between the two adjacent second electrodes 222. Electrode 221. In addition, the two first electrodes 221 corresponding to the two adjacent second electrodes 222 are respectively disposed on different sides of the two adjacent second electrodes 222 in the first direction X. By designing the shape of the second electrode 222 to be stepped and the two second electrodes 222 are disposed adjacent to each other back to back, the space can be raised.The efficiency of use can further improve the touch resolution.
如第15圖所示，本發明之第九實施例提供一互電容式觸控裝置209。與上述第三實施例不同的地方在於，互電容式觸控裝置209可包括一第一光學補償結構231以及一第二光學補償結構232，第一光學補償結構231與第二光學補償結構232係設置於基板210上，且第一光學補償結構231與第二光學補償結構232係分別位於觸控元件220之兩相對側，用以達到所需之光學補償效果。舉例來說，第一光學補償結構231可部分設置於基板210與觸控元件220之間，而觸控元件220可設置於第一光學補償結構231與第二光學補償結構232之間。此外，觸控元件220與第二光學補償結構232之間亦可視需要設置一保護層250，但並不以此為限。本實施例之第一光學補償結構231與第二光學補償結構232的材料特性與上述第三實施例之光學補償結構230相似，故在此並不再贅述。本實施例之第一光學補償結構231與第二光學補償結構232亦可視需要應用於本發明之其他實施例中。As shown in FIG. 15, a ninth embodiment of the present invention provides a mutual capacitive touch device 209. The difference from the third embodiment is that the mutual capacitive touch device 209 can include a first optical compensation structure 231 and a second optical compensation structure 232. The first optical compensation structure 231 and the second optical compensation structure 232 are The first optical compensation structure 231 and the second optical compensation structure 232 are respectively disposed on opposite sides of the touch element 220 to achieve a desired optical compensation effect.
