Description

201207705 六、發明說明：【發明所屬之技術領域】本發明隸屬一種觸控面板之技術領域，具體而言係指一種在同一水平或垂直之不同觸點阻抗產生梯度現象、且能防止電流互相抵銷的表面電容式之觸控面板，藉以使該觸控面板具有多觸點判定之功能。【先前技術】按，電子設備發展史中，鍵盤、滑鼠與觸控板等輸 • 入介面的出現，解決了輸入控制的問題。不過，這些輸入介面所佔空間不小，例如，筆記型電腦或手機一半體積都被鍵盤佔據。若能省下鍵盤空間，自然能提升產品可攜性，最可行的方式，就是直接於面板以觸控方式進行操作。觸控面板確實能取代大多數鍵盤、滑鼠功能，並賦與使用者更直覺、便利的操作體驗；以更大的面板替代鍵盤，還能設計出更輕薄、時尚造型；加上完全採用固態面板技術，不需擔心鍵盤、滑輪…等機械零件故 Φ 障的問題。從技術原理來區別觸控面板，其可分為電阻技術觸控面板、電容技術觸控面板、紅外線技術觸控面板、表面聲波技術觸控面板、電磁技術觸控面板與光學技術觸控面板等。其中電阻式觸控面板的定位準確，但其價格頗高，且怕刮易損。紅外線技術觸控面板的價格低廉，但其外框易碎，容易產生光干擾，曲面情況下失真；而表面聲波觸控面板解決了以往觸控式螢幕的各種缺陷，清晰抗暴，適於各種場合，缺憾是面板表面的水滴、塵 201207705 土會使觸控面板變的遲鈍，甚至不卫作。因此目前觸控面板開發的在考量兼具耐雜、成本、反錢度與便利性下’電喊糖崎與電料板成為主力產品。近年來，受到智慧型手機貼心的觸控介面，讓智慧型手機有機會臝得更多人的青睞。而多現【如iPh〇ne、HTC等智慧财機】，更造成^用^ 的新革命’用戶能以更直觀的方式使用應用該多點觸控面板的電子產品。不過，在前述多點觸控式智慧型手機推出已有一段時間’但仍未見到市場上接二連三的相似概念產品出可f得在技術的實踐上確實存在著—道頗高的門播。目前在市場上存在多種觸控技術，只有電容式技術實現多點觸控的功能。再進-步看，電容式觸控又可刀為表面電容式【Surface Capacitive】和投射電容式【Projective Capacitive】兩種作法；以八中表面電谷式的技術作法來看，如第一圖所示士為一傳統表面電容式觸控面板。該觸控面板（1〇)係一透明基板（11)、一透明導電層（12)、一電極圖 (13)及一絕緣保護用之硬化層（14)所構成，其透明基板（U )可為玻璃、塑膠，該電極圖案層（13) '、形成圍繞成矩形之兩相對X側電極（131)與兩相對則電極（132)形成於該透明導電層（12)的周緣部份， =補償該透明導電層（12)上之一電場的曲線分佈。，如第二圖所示，該觸控面板（1〇)的四角落處各連外之導線（15卜152、153、154)相接，用以扒 4 201207705 別接收一交流感測訊號【AC1、AC2、AC3、AC4】’以供量測觸控面板（i〇)上之一個觸點p的位置用。在實際工作時，該等交流感測訊號AC1、AC2、AC3、AC4為振幅大小相同之交流方波或弦波電壓訊號’此時各連外導線 (151、152、153、154)上各有一電流 II、12、13 及 14通過。藉由量取每一連外導線（15卜152、153、154) 之在該觸點P出現前與出現時的電流變化量ΔΙ1、 △ 12、△ 13及△ 14，該觸點P位置的X、Y座標便可依下式被計算出： Χ=(Δ Ι3+Δ Ι4-Δ Il-Δ 12)/( Δ Il + Δ Ι2+Δ 13+Δ 14) Υ=(Δ ΙΗΔ Ι4-Δ 13-Δ 12)/(Δ 11 +Δ Ι2+Δ 13+Δ 14) 因此在運作架構上，系統會在透明導電層（12)產生一個均句電場，當手指接觸面板會出現電容充電效應，面板上電極圖案層（13)的各透明Χ、Υ侧電極（13卜 132)與手指間形成電容耦合，進而產生電容變化，控制器只要量測四個角落電流強度，就可依電流大小計算接觸位置。由於其係透過手指接觸觸控面板造成靜電場改變進行偵測’其中單點觸控電容式技術，其實已相當成熟，也就是表面電容式（Surface Capacitive)。此技術架構較單純’只需一面透明導電層（12)即可實現，而且此透明導電層（12)不需特殊感測通道設計，週邊只需接 4條導線（151、152、153、154)和接地線即可，生產難度及成本都可降低。而其最大的限制則是，它無法實現多點觸控功能，主要係因其在實際工作業時，如同時 201207705 施於二個以上觸點’而進行兩觸點間之手勢動作時【如縮放、旋轉或拖拉等】，其可能因兩指位置呈對應狀而使輸出之電流相互抵銷，造成其觸點或動作的誤判，故現有表面電容式觸控面板並不是多點觸控的理想技術。也因此。投射電容式【Projected Capacitive】技術就成了實現多點觸控的希望所在。如第三圖為一傳統投射電容式觸控面板之立體分解圖。該電容式觸控面板 (20)係由一透明基板（21)、一 X透明電極圖案層（22)、一透明介電層（23)及一 Y透明電極圖案層（24)由下往上疊合形成，其中X與Y透明電極圖案層（22、24) 上各形成行/列之感測圖案（25)【sensing element】，用以與其它元件配合為用而判定該觸控面板（20)上一或多個觸點的存在，其中X與Y透明電極圖案層（22、 24)之感測圖案（25)並與複數條外接導線（28)相接。相較於表面電容式，投射電容式採單層或多層樣式化【patterned】形成行/列交錯感測圖案（25)【sensing element】矩陣。如此一來，整個使用生命週期中，不需透過校準就能得到精確觸控位置，而且可以使用較厚的覆蓋層，也能做到多點觸控操作。但這在市場上仍屬於相當先進且複雜的技術，其螢幕的感測方式必須採用多攔【column】和多列【row】的矩陣【Matrix】掃描模气，又可分為軸交錯式【Axis Intersect】和所有觸點可定位式【All Points Addressable，APA】兩種感測榮幕, 前者的實踐上較為容易’對於運算及儲存資源的要求也較低’不過如果想實現精確的兩點觸控定位，還是得採用APA的感測技術。木 201207705 但不論何者，就目前的製造技術而言，其均需使用到較高的製造技術，因此其製造成本極高，不符實際使用的需求’更甚者受到其運算、儲存資源不足與感測準確度的影響，目前投射電容式觸控面板的只能用於小尺寸面板的量產上’對於使用中、大尺寸面板之產業【如筆記型電腦、工業電腦、P0S系統、ATM、醫療器材、監視器、、遊戲機、博奕產業等等】，尚無法有效的滿足其多點觸控的需求。換言之，由於表面電容式觸控面板具有架構簡易、且易於製成及低成本的生產優勢，同時表面電容式觸控產品更具防塵、防火、防到、強固耐用及具有高解析度等優點，故如能開發出具有多觸點判定功能的表面電容式觸控面板，則可兼具使用的便利性與低成本之效。有鑑於此’本發明人乃針對前述現有可判定多觸點的觸控面板所面臨的問題深入探討，並藉由多年從事相關產業的研發與製造經驗，而積極尋求解決之道，經不斷努力的研究與試作，終於成功的開發出一種表面電容式觸控面板之多點觸控結構及其方法，藉以克服現有者製造難度與生產成本面等所造成的不便與困擾。【發明内容】因此’本發明之主要目的係在提供一種表面電容式觸控面板之多點觸控方法，其能讓觸控面板在同一水平或垂直之觸點阻抗產生梯度現象，防止兩觸點移動時之電流互相抵銷，進而可有效地判定觸控面板上不同的觸點的座標，以滿足表面電容式觸控面板的多觸點需求。 201207705 又，本發明之另一主要目的係在提供一種表面電容式觸控面板之多點觸控結構，藉以能大幅约仆冬★ 控面板的構成’且降低其製造難度’而能^效降低^成本0 據此，本發明主要係透過下列的技術手段，來具體實際前述之目的與功效；該觸控面板至少係由一透明基板、一透明導電層及一電極圖案層所構成’其中電極圖案層係於觸控面板上、下邊緣分設有相對之至少一第一 X侧電極與至少一第二X側電極，又電極圖案層係於觸控面板左、右邊緣分設有相對之相對之至少一第一 γ侧電極與至少一第一 Y侧電極，且第一、一 X侧電極與第一、二γ侧電極以矩形圍繞於觸控面板表面周緣而成，其中第一、二X侧電極係呈阻抗以等差或等比方式而遞減或遞增，又第一、二Y侧電極並係呈阻抗以等差或等比方式而遞減或遞增，且第一、二X侧電極與第一、二γ侧電極之端部分別電氣連接有一供量測輸出電流之導線。藉此，透過本創作前述技術手段的具體實現，讓本發明之觸控面板在同一水平或垂直之觸點阻抗產生梯度現象，以有效兩個不同觸點之電流在相對縮放、旋轉或拖拉的移動過程中互相抵銷，從而可有效地判定觸控面 ^上不同的觸點的座標，以滿足表面電容式觸控面板的多觸點需求，且能大幅簡化多點式觸控面板的構以降低其製造難度與成本。為使貴審查委員能進一步了解本發明的構成、特 201207705 的’以下乃舉本發明之較佳實施例，並配合舻；絲田s明如后同時讓熟悉該項技術領域者能夠具體貫施。【實施方式】 β盆月^種表面電容式觸控面板之多點觸控結構中:所右關Π列不之本發明的具體實施例及其構件 am 後、左與右、頂部與底部、上部與下201207705 VI. Description of the Invention: [Technical Field] The present invention belongs to the technical field of a touch panel, and specifically refers to a gradient phenomenon generated by different contact impedances at the same horizontal or vertical direction, and can prevent current from abutting each other. The surface capacitive touch panel of the pin enables the touch panel to have a multi-contact determination function. [Prior Art] According to the development history of electronic devices, the emergence of input interfaces such as keyboards, mice and touchpads has solved the problem of input control. However, the space occupied by these input interfaces is not small. For example, half of the volume of a notebook or mobile phone is occupied by the keyboard. If you can save keyboard space, you can naturally improve the portability of the product. The most feasible way is to operate the touch panel directly on the panel. The touch panel can really replace most of the keyboard and mouse functions, and give users a more intuitive and convenient operation experience; replace the keyboard with a larger panel, and design a thinner and more stylish style; plus fully solid state Panel technology, no need to worry about mechanical parts such as keyboards, pulleys, etc. The technical principle is to distinguish the touch panel, which can be divided into a resistance technology touch panel, a capacitive technology touch panel, an infrared technology touch panel, a surface acoustic wave technology touch panel, an electromagnetic technology touch panel, an optical technology touch panel, and the like. . Among them, the resistive touch panel is positioned accurately, but its price is quite high, and it is afraid of scratching. Infrared technology touch panel is low in price, but its frame is fragile, it is easy to produce light interference, and the surface is distorted; and the surface acoustic wave touch panel solves various defects of the previous touch screen, clear and anti-riot, suitable for various occasions. The shortcoming is the water droplets on the surface of the panel, the dust 201207705 soil will make the touch panel become dull, even unprotected. Therefore, at present, the development of touch panel is considered to be resistant to miscellaneous, cost, anti-money and convenience. In recent years, the smart touch screen of smart phones has given smart phones the opportunity to be more popular. However, many [such as iPh〇ne, HTC and other smart money machines] have created a new revolution in the use of ^, users can use the electronic products using the multi-touch panel in a more intuitive way. However, in the case of the aforementioned multi-touch smart phones, it has been a while for a while, but the similar concept products that have not been seen in the market have been seen in the practice of technology. At present, there are many touch technologies on the market, and only capacitive technology realizes the function of multi-touch. In the further step, the capacitive touch can be a surface capacitive type [Surface Capacitive] and a projected capacitive type [Projective Capacitive]. According to the eight-surface electric valley type technology, as shown in the first figure. The taxi is a conventional surface capacitive touch panel. The touch panel (1) is composed of a transparent substrate (11), a transparent conductive layer (12), an electrode pattern (13) and a hardened layer (14) for insulating protection, and the transparent substrate (U) The electrode pattern layer (13)' may be glass, plastic, and the opposite X-side electrode (131) and the opposite electrode (132) formed in a rectangular shape are formed on a peripheral portion of the transparent conductive layer (12). = Compensating for the curve distribution of an electric field on the transparent conductive layer (12). As shown in the second figure, the wires (15, 152, 153, and 154) connected to the four corners of the touch panel (1〇) are connected to each other for receiving the AC sensing signal. AC1, AC2, AC3, AC4]' is used to measure the position of a contact p on the touch panel (i〇). In actual operation, the AC sensing signals AC1, AC2, AC3, and AC4 are AC square wave or sinusoidal voltage signals of the same amplitude. At this time, each of the external wires (151, 152, 153, 154) has one Currents II, 12, 13 and 14 pass. By measuring the amount of current change ΔΙ1, Δ12, Δ13, and Δ14 of each of the external wires (15, 152, 153, 154) before and after the occurrence of the contact P, the X of the contact P position The Y coordinate can be calculated according to the following formula: Χ=(Δ Ι3+Δ Ι4-Δ Il-Δ 12)/( Δ Il + Δ Ι2+Δ 13+Δ 14) Υ=(Δ ΙΗΔ Ι4-Δ 13 -Δ 12) / (Δ 11 + Δ Ι 2+ Δ 13 + Δ 14) Therefore, in the operational architecture, the system will generate a uniform electric field in the transparent conductive layer (12), and the capacitive charging effect will occur when the finger touches the panel. The transparent Χ and the Υ-side electrodes (13 and 132) of the upper electrode pattern layer (13) form a capacitive coupling with the fingers, thereby generating a capacitance change, and the controller can measure the contact current according to the current level by measuring the current intensity of the four corners. position. Because it touches the touch panel with a finger to cause electrostatic field changes for detection, the single-touch capacitive technology is quite mature, that is, Surface Capacitive. The technical architecture is simpler than that of a transparent conductive layer (12), and the transparent conductive layer (12) does not require a special sensing channel design, and only four wires are required in the periphery (151, 152, 153, 154). ) and the grounding wire can be used, and the production difficulty and cost can be reduced. The biggest limitation is that it can't realize the multi-touch function, mainly because it is used in the actual work, such as the 201207705 is applied to two or more contacts', and the gesture between the two contacts is performed. Zoom, rotate or drag, etc., which may cause the output currents to cancel each other due to the corresponding position of the two fingers, causing misjudgment of their contacts or actions, so the existing surface capacitive touch panel is not multi-touch Ideal technology. So. Projected Capacitive technology is the hope of multi-touch. The third figure is an exploded perspective view of a conventional projected capacitive touch panel. The capacitive touch panel (20) is composed of a transparent substrate (21), an X transparent electrode pattern layer (22), a transparent dielectric layer (23) and a Y transparent electrode pattern layer (24) from bottom to top. Forming a stack, wherein the X and Y transparent electrode pattern layers (22, 24) each form a row/column sensing pattern (25) [sensing element] for use in conjunction with other components to determine the touch panel ( 20) The presence of one or more contacts, wherein the sensing patterns (25) of the X and Y transparent electrode pattern layers (22, 24) are in contact with a plurality of external leads (28). Compared to the surface capacitance type, the projected capacitive single layer or multi-layer patterning forms a row/column interleaved sensing pattern (25) [sensing element] matrix. In this way, the precise touch position can be obtained without calibration through the entire life cycle, and a thicker overlay layer can be used, as well as multi-touch operation. However, this is still a fairly advanced and complex technology in the market. The sensing method of the screen must use multi-column [column] and multi-row [row] matrix [Matrix] scanning mode gas, and can be divided into axis interleaved [ Axis Intersect] and all contact-positionable (All Points Addressable, APA) two sensing glory, the former is easier to practice 'lower requirements for computing and storage resources' but if you want to achieve two precise points Touch positioning, or APA's sensing technology. Wood 201207705 But no matter what, in terms of current manufacturing technology, it needs to use higher manufacturing technology, so its manufacturing cost is extremely high, and it is not suitable for actual use. 'More than the lack of computing and storage resources. The impact of measurement accuracy, the current projected capacitive touch panel can only be used for the mass production of small-sized panels. 'For industries that use medium and large panels [such as notebook computers, industrial computers, P0S systems, ATMs, medical Equipment, monitors, game consoles, gaming industry, etc., can not effectively meet the needs of multi-touch. In other words, since the surface capacitive touch panel has the advantages of simple structure, easy manufacture, and low cost, the surface capacitive touch product is more dustproof, fireproof, resistant, durable, and has high resolution. Therefore, if a surface capacitive touch panel with multi-contact determination function can be developed, the convenience and low cost of use can be achieved. In view of the above, the present inventors have intensively discussed the problems faced by the above-mentioned existing determinable multi-touch touch panels, and actively pursued solutions through years of experience in research and development and manufacturing of related industries, and have continuously worked hard. The research and trials finally succeeded in developing a multi-touch structure and method for a surface capacitive touch panel, thereby overcoming the inconvenience and trouble caused by the existing manufacturing difficulty and production cost. SUMMARY OF THE INVENTION Therefore, the main object of the present invention is to provide a multi-touch method for a surface capacitive touch panel, which can cause a gradient phenomenon of a touch panel at the same horizontal or vertical contact impedance to prevent two touches. When the point moves, the currents cancel each other, thereby effectively determining the coordinates of different contacts on the touch panel to meet the multi-contact requirements of the surface capacitive touch panel. 201207705 In addition, another main object of the present invention is to provide a multi-touch structure of a surface capacitive touch panel, thereby greatly reducing the composition of the control panel and reducing the manufacturing difficulty thereof. ^ Cost 0 According to the present invention, the present invention mainly utilizes the following technical means to specifically implement the foregoing objects and effects; the touch panel is composed of at least a transparent substrate, a transparent conductive layer and an electrode pattern layer. The pattern layer is disposed on the touch panel, and the lower edge is respectively provided with at least one first X-side electrode and at least one second X-side electrode, and the electrode pattern layer is respectively disposed on the left and right edges of the touch panel. Opposite at least one first γ-side electrode and at least one first Y-side electrode, and the first and the X-side electrodes and the first and second γ-side electrodes are formed in a rectangular shape around the periphery of the touch panel surface, wherein the first The two X-side electrodes are in decreasing or increasing impedance in an equal or equal ratio, and the first and second Y-side electrodes are in decreasing or increasing impedance in an equal or equal ratio, and the first and second X sides are Electrode with the first, An end portion of the γ-side electrode are electrically connected to a measuring output current supply conductor. Therefore, through the specific implementation of the foregoing technical means, the touch panel of the present invention generates a gradient phenomenon at the same horizontal or vertical contact impedance, so that the currents of the two different contacts are relatively scaled, rotated or dragged. The offsets in the moving process can effectively determine the coordinates of different contacts on the touch surface to meet the multi-contact requirements of the surface capacitive touch panel, and can greatly simplify the structure of the multi-touch panel. To reduce its manufacturing difficulty and cost.
