New Description: , [New Technology Area] This creation is about a touch pad, especially a touch pad that can greatly simplify the structure and has both resistance and capacitance. By. [Prior Art] With the continuous development of portable and interactive electronic products, the touchpad has almost become an indicator of the electronic products of this surface. Under the urging of market demand, the quality of the touchpad production is mixed, and the price is reduced and the output is increased. The control panel can be widely used in various electronic products. The touchpad's 'Ying County's multi-dimension can be divided into four types: resistive touchpad, capacitive touchpad, sonic touchpad and optical touchpad. Because of the different application principles of these touch panels, their processes, functions, usage methods, advantages and disadvantages, and even application levels also have their own characteristics. Because of the touch-sensitive induction, the resistive touch panel is not limited to any kind of touch medium. Fingers, pencils, access cards or gloves can be used. Plus, the products are cheap, so the main applications are: mobile phones. Consumer electronic products such as personal digital assistants (10) and global satellite positioning systems (10). Conversely, due to the complicated process steps of the capacitive touch panel, the control chip and the circuit are relatively more complex than the resistive touch panel, so they are mostly used in high-priced electronic products such as notebook computers and bank fiber dispensers. The sonic disk and M364242 type touchpad are not mature enough for their technology and process, so they are used in high-priced electronic products of large size. The structure of the resistive touch panel is generally composed of a flexible conductive plate 14 and a rigid conductive plate 18 located underneath, and a plurality of spacers 16 are disposed in the middle of the two flat plates. The two plates have no electrical contact with each other without the force of C. The measurement method is mainly divided into two types: a four-wire type in which both upper and lower conductive plates can be received; the other is a five-wire type in which the upper conductive plate has only a receiving function. Because the four-wire type of upper and lower conductive plates can be received, that is,
其上下兩塊導電板邊緣上各設有一對電極，而且，一對是X — 軸對稱的電極’另—對則是Y軸對稱的電極。當χ軸對稱之 兩邊緣相對電極被施加—頓斜，料電板上各點便會產 生不同的包位’此時’另一塊導電板上的丫軸對稱電極便可 作為量測用，在上下兩塊導電板受按Μ而局部接觸時，按壓 點Α1上的電位便可經由γ軸對稱電極測出。此時，若上下 導電板上皆鑛有均勻分布的導電膜，則該按壓點Α1的電位 便3跟雜壓點Α1與邊緣兩電極之間的n直轉呈線性關 係，如此’該按壓點A1在X軸與γ軸的分量便可從上下導 電板交替量測的電位得出。 五線式偵測按壓點位置的方式與四線式的相同，不同點 在於五線式的上方導電膜15只有接收的功能，實施X、γ軸 M364242 電[差之電極171、172、173、174全在下方導電膜17上， 而上方導電膜15上只有存在量湖的電極⑸。如第3A1J 所示田於Y軸稱電極171、172上施加電壓差時（實線電 路）电極171與電極172之間會形成線性電位差，而電才亟 151便會回傳該按壓點A1的電位，其約略等於 剛/⑻獨，其找阻R1射2又大致等於—均勻分布導 電膜之面電阻乘以該按壓點與電極171、172之垂直距離， 便可由此得出該按壓點在X軸的分量；同理，當實施電路改 為第3A圖令的虛線連接時’該上方導電膜15便可以量測出 5亥按壓點A1在γ轴上的分量。 由於電阻R1、R2、R3與R4係與該按壓點μ與電極pi、 172、173、174之間的垂直距離呈線性相關，所以，計算出 的X、Y軸分量的解析度與該按壓點A1電性接觸的範圍有 關，也就是跟按壓使用物體的尖端粗細有關。因此，電阻式 觸控板較適合義於手寫嘴圖料需要較高解析度的指標 操作上’例如：GPS導航系統等小型電子產品、繪圖板或手 寫板等等。然而，難轉觸控板的方式，卻科造成上下 導電膜15、17的磨損與按壓頂板丨4的應變疲乏，故使用壽 命有限並不適合常態性或於使用頻繁之公共場合中使用；同 時’電阻式觸控板的解析度係與使用之媒介尖端粗細有關， 倘若使用之媒介尖端較粗(例如：較大手指或鈍型物質），則 不易測出按壓點之位置；此外，由於導電膜的面電阻會隨著 M3 64242 溫度而變化，電阻式觸控板計算出的距離會隨著溫度變化而 產生偏移，所以並不適用於溫度車父尚或溫度變化過大的環境 中使用。 由此可知，雖然電阻式觸控板可以操作解析度較高的動 作，不過，由於其量測距離的準確度係與導電膜的品質有很 大的關係，分布越均句的導電膜，其接收電壓與面電阻的線 性關性越好，該按壓點A1的距離也就越準確。然而，當導 電膜均勻度不夠、操作次數多有磨損、或是溫度升高時，都 會使後續的訊號處理模組計算出的距離產生偏移。同時，傳 統電阻式觸控板並不能感應多物體的接觸行為’所以在應用 上’傳統電阻式觸控板仍然有許多的限制。 因此，能彌補電阻式觸控板不足的電容式觸控板亦具有 相當的市場佔有率。如同電阻式觸控板—樣，電容式觸控板 亦可以分職測出χ、γ軸的分量，叹感應原理與實施物 體不同。兩軸電容式觸控板的大致結構如第3Β圖所示，其 操作方法係個手指或是具電性之物於面板1G表面接 觸’而該面板10下方係為複數第一軸線跡lla、llb所在之 第一轴感應層Π。當手減導體置於該面板上時，其具有的 電!·生條件將使該複數鄉_軸線跡林同水平麟上產生 不同的電容反應，同時，若將該複數條第一軸線跡以χ或γ 軸對稱方式_排序，便可以從各條的電容反應強弱計算出 趣觸點Α1在Υ或X軸上的分量。同樣地，在該第一轴感 M36(4242 I » '應層11下方再佈置一絕緣層12以及分佈有若干第二軸線跡 13a之第二軸感應層13，並將該第二軸線跡13a以Y或X軸 對稱方式陣列排序，便可以擷取出該接觸點A1在X或Y軸 上的分量。 由於電容式觸控板係感應該手指或導體上電性所造成 之電谷變化，並不需要加力按壓觸控板，因此，不會對觸控 板的薄膜電極或按壓面板產生磨損或雜疲乏，使用壽命相 _ 當的長，比之電阻式觸控板更適用於常態性或經常使用之公 共性電子產品上。 〇除此之外，傳統電阻式觸控板接收用的導電膜只能接收 2點接觸峨，故只_於單__接觸；反之，由於電 觸控板具有複數條獨立接線的第一軸線跡與第二軸線 f所以可以分辨出多點操作的接觸，讓觸控_功能更加 夕几化例如.最新流行的iph〇ne手機，使用多手指觸控 • 來進行不同手勢觸發，簡化操作手續増加使用功能。 相對於電阻式敏板肢周遭溫度與使用次數的影

有其應用的範ϋ以及市場需求。然而，當攜帶獅產品越做 越小，使用功能部越來越多時，單單使用電阻式觸控板或電 谷式觸控板已不能滿足新式產品的需求。例如：電阻式觸控 板7〇成傳統單點觸發的指標功能，當需要使用多手指手 勢觸發功能時卻不能執行’此外，電阻式觸控板只適用於個 人非吊態使用、或使用哥命不長的產品上，也容易受到溫度 的影響而產生位置飄移現象；然而，電容式觸控板雖可執行 多手指手勢觸發的功能，但卻沒有電阻式觸控板使用筆形物 尖端操作之解析度，也容易受人體狀況、環境濕度、及周遭 電磁波強度的影響。 故一種疊合電容式觸控板A以及電阻式觸控板B的新型 板體係揭示於中華民國新型專利證號M321553中。如第1圖 所示’該專利中所述之第一觸控板A即為：面板1〇、第一幸由 感應層11、絕緣層12、第二轴感應層13以及頂板Η依序 定合而成，具有傳統電容式觸控板的功能；而該專利中所述 之第二觸控板B即為：頂板14、上方導電膜15、間隔球放 置區16、下方導電膜17以及基板18依序疊合而成，具有傳 統電阻式觸控板的功能。雖然上述之專利可以將傳統之電阻 式及電容式結合成單一之觸控板結構；但基本上，該專利僅 係直接將一傳統電容式觸控板與一傳統電阻式觸控板相互 M364242 1而成’只節省了電容式與電阻式觸控板朗使用的 緣體材f而已。雖然，使用上可同時或㈣使用電容 式二電阻式繼板的魏，卻造_控板赌解度與重量 變仔加乘，使得鱗利提㈣多I觸控板最可望_的攜帶 型電子產品㈣更厚更重，違反該項產品設計的本質。 j除此之外’電容式與電阻式/f狀結構的加乘，使得原先 ，必需斤斤計較的觸她透光率更加雪上加霜。舉例來說， 右以原先具有95%透光率的電容式觸控板來看，疊加上一具 ㈣腿絲的電阻式糖板，其透光率#場就降低為概、， 祕的透絲與市場上現行稿控螢幕透光率減太大，產 品的市場競爭性將大大的減少。 採用電谷式觸控板在上電阻式觸控板在下的疊合板 體，其在雜式_應能力也將大幅減少。由於電阻式觸控 板係根據上導電膜與下導電膜接觸時的電壓來決定按壓點 A1的位置，若該上導電膜上覆蓋的層數越來越厚，例如：該 絕緣層12加上面板1〇的厚度可能就超過lmm以上，在加上 原本的頂板14的厚度’將使得要達到電氣接觸的按壓動作 要非常的大’這將影響該電阻式觸控板的靈敏度與反應速 度’對於依賴電阻式觸控板操作之手寫與繪圖功能會出現運 行困難、斷線、不連續的情形。 直接採用電容式與電阻式疊加的觸控板在產品製程與 M364242 成本控制上也存在著不少賊。第―，使財加的方式，產 品的製造與成本並沒有因為疊合而節省還是需要電容式與 電阻式兩個觸控板的製程與成本’同時還多了將兩塊觸控板 組合的製程；第二’電容式與電阻式觸控板的連接排線上依 舊是各走各的線，並沒有因為疊合而精簡，反而成品後的排 線數目與厚度都增加了—倍；第三，由於多出—條傳輸排 線，其連接至後續訊號處理模組之走線也會需要重新設計， 排線的組破與走線的佈置都將增加產品的製程與成本。 因此，如何能提供一種兼具電阻式與電容式觸控板優 點，同時觸控板的層數、厚度以及排線數目都不致於增加， 又觸控板的靈敏度與透光性也不致於降低很多之多元感應 觸控板係為本創作人致力達成之目標。 【新型内容】 為解決上述習知技術使用上的問題，本創作提出一種多 元感應觸控板(touch pad for variety of sensing)，能同時兼具電 容式與電阻式觸控板的優點，卻僅需要兩層組成結構，包 括：-上導電相及-下導電層。該上導電層又具有複數上 感應部以及與其躲連接之上接合部，射，該上感應部係

symmetrical electrodes. When the two edges of the yaw axis are oppositely applied to the opposite electrode, different points will be generated at the points on the material board. At this time, the 丫-axis symmetric electrode on the other conductive plate can be used as a measurement. When the upper and lower conductive plates are partially contacted by the click, the potential on the pressing point Α1 can be measured via the γ-axis symmetric electrode. At this time, if the upper and lower conductive plates are uniformly distributed with a conductive film, the potential of the pressing point Α1 is linear with the n-turn between the hybrid pressure point Α1 and the edge electrodes, so that the pressing point The components of A1 on the X-axis and the γ-axis can be derived from the potentials measured alternately from the upper and lower conductive plates. The five-wire type of detecting the position of the pressing point is the same as that of the four-wire type. The difference is that the five-wire upper conductive film 15 has only the receiving function, and the X and γ axes M364242 are electrically operated [the electrodes 171, 172, and 173 of the difference, 174 is entirely on the lower conductive film 17, and only the electrode (5) of the amount of lake is present on the upper conductive film 15. When a voltage difference is applied to the Y-axis weighing electrodes 171 and 172 as shown in the 3A1J, a linear potential difference is formed between the electrode 171 and the electrode 172, and the electric switch 151 returns the pressing point A1. The potential, which is approximately equal to just/(8) alone, and its resistance R1 is substantially equal to - the uniform resistance of the surface resistance of the conductive film multiplied by the vertical distance between the pressing point and the electrodes 171, 172, thereby obtaining the pressing point In the X-axis component; similarly, when the implementation circuit is changed to the dotted line connection of the 3A-th order, the upper conductive film 15 can measure the component of the 5-H press point A1 on the γ-axis. Since the resistances R1, R2, R3, and R4 are linearly related to the vertical distance between the pressing point μ and the electrodes pi, 172, 173, and 174, the calculated resolution of the X and Y-axis components and the pressing point The range of A1 electrical contact is related to the thickness of the tip of the object being pressed. Therefore, the resistive touch panel is more suitable for the handwriting of the mouthpiece, which requires a higher resolution index, such as a small electronic product such as a GPS navigation system, a drawing board or a handwriting board, and the like. However, the manner in which the touch panel is difficult to turn, the wear and tear of the upper and lower conductive films 15, 17 and the strain on the top plate 丨 4 are fatigued, so the service life is limited and is not suitable for normal use or in public places where the use is frequent; 'The resolution of the resistive touch panel is related to the thickness of the tip of the medium used. If the tip of the medium used is thick (for example, a large finger or a blunt substance), it is difficult to measure the position of the pressing point; in addition, due to the conductivity The sheet resistance of the film will change with the temperature of M3 64242. The calculated distance of the resistive touch panel will shift with temperature, so it is not suitable for use in environments where the temperature is too high or the temperature is too large. It can be seen that although the resistive touch panel can operate with a high resolution, the accuracy of the measured distance has a great relationship with the quality of the conductive film, and the more uniform the conductive film is distributed, The better the linearity of the receiving voltage and the sheet resistance, the more accurate the distance of the pressing point A1. However, when the uniformity of the conductive film is insufficient, the number of operations is excessively worn, or the temperature rises, the distance calculated by the subsequent signal processing module is shifted. At the same time, traditional resistive touch panels do not sense the contact behavior of multiple objects. So in application, traditional resistive touch panels still have many limitations. Therefore, a capacitive touch panel capable of making up for the lack of a resistive touch panel has a considerable market share. Like a resistive touch panel, a capacitive touch panel can also measure the components of the χ and γ axes separately. The principle of sigh induction is different from that of the implementation object. The general structure of the two-axis capacitive touch panel is as shown in FIG. 3, and the operation method is that a finger or an electrical object contacts the surface of the panel 1G, and the lower portion of the panel 10 is a plurality of first axis traces 11a, The first axis sensing layer where llb is located. When the hand-reduction conductor is placed on the panel, the electric power of the hand-wounding condition will cause the complex township-axis trace forest to generate different capacitance responses on the horizontal lining, and at the same time, if the plurality of first-axis traces are χ or γ Axisymmetric _ sorting, you can calculate the component of the interesting contact Α1 on the Υ or X axis from the capacitance response of each strip. Similarly, an insulating layer 12 and a second axis sensing layer 13 distributed with a plurality of second axis traces 13a are disposed under the first axis sense M36 (4242 I » ' should layer 11 and the second axis trace 13a By sorting the array in a Y- or X-axis symmetry manner, the component of the contact point A1 on the X or Y axis can be extracted. Since the capacitive touch panel senses the electric valley change caused by the electrical power of the finger or the conductor, There is no need to pressurize the touchpad, so there is no wear or fatigue on the membrane electrode or the pressing panel of the touchpad. The long life is more suitable for normality than the resistive touchpad. Commonly used in public electronic products. In addition, the conductive film for receiving traditional resistive touch panels can only receive 2 points of contact, so only _ single __ contact; otherwise, due to the electric touch board The first axis trace and the second axis f with a plurality of independent wires can distinguish the contact of the multi-point operation, and the touch_function is more complicated. For example, the latest popular iph〇ne mobile phone uses multi-finger touch. To trigger different gestures and simplify the operator増 使用 使用 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对Condition, ambient humidity = acidification, capacitive touchpad is not used when the temperature is too humid ring brother π gloves or use water-filled fingers, and devices, equipment or products that will generate electromagnetic waves t, especially the light-emitting electromagnetic wave frequency 7 M364242 is within the range of the touch panel capacitance reaction. It is also because the resistive and capacitive touch panels have their own advantages and disadvantages, so each has its application and market demand. When the lion products are getting smaller and smaller, and more and more functional parts are used, the use of resistive touch panels or electric valley touch panels alone cannot meet the needs of new products. For example: resistive touch panels 7〇 The traditional single-point trigger indicator function can not be executed when the multi-finger gesture trigger function is needed. In addition, the resistive touch panel is only suitable for personal non-suspended use, or use of a life-threatening The product is also susceptible to temperature drift and position drift; however, the capacitive touch panel can perform multi-finger gesture triggering, but there is no resolution of the resistive touchpad using the tip of the pen. It is also susceptible to human body conditions, environmental humidity, and the intensity of electromagnetic waves around it. Therefore, a new type of laminated capacitive touch panel A and resistive touch panel B is disclosed in the Republic of China new patent number M321553. 1 shows that the first touch panel A described in the patent is: panel 1 〇, first fortunately by the sensing layer 11, the insulating layer 12, the second axis sensing layer 13 and the top plate 定 are sequentially combined The function of the conventional capacitive touch panel is as follows: the second touch panel B described in the patent is: the top plate 14, the upper conductive film 15, the spacer ball placement area 16, the lower conductive film 17, and the substrate 18 The sequence is superimposed and has the function of a conventional resistive touch panel. Although the above patent can combine the traditional resistive and capacitive modes into a single touchpad structure; basically, the patent only directly connects a conventional capacitive touchpad and a conventional resistive touchpad to each other. M364242 1 It has only saved the edge material f used by the capacitive and resistive touch panels. Although, the use of the same or (d) the use of capacitive two-resistance type of the Wei, but the _ control board gambling and weight change, so that the sturdy (four) multi-I touch board is the most expected to carry Type electronic products (4) are thicker and heavier, in violation of the nature of the product design. In addition to this, the combination of capacitive and resistive/f-like structures makes it necessary for the original light to be more sensitive to the light transmittance. For example, the right side of the capacitive touch panel with 95% transmittance, the superposition of a (four) leg wire of the resistive sugar plate, the light transmittance of the field is reduced to a general, secret Silk and the market's current manuscript control screen transmittance is too large, and the market competitiveness of products will be greatly reduced. With the electric valley type touch panel on the lower laminated board with the upper resistive touch panel, its ability in the hybrid mode will also be greatly reduced. Since the resistive touch panel determines the position of the pressing point A1 according to the voltage when the upper conductive film is in contact with the lower conductive film, if the number of layers covered on the upper conductive film is thicker and thicker, for example, the insulating layer 12 is added. The thickness of the panel 1 可能 may exceed 1 mm or more, and the thickness of the original top plate 14 will make the pressing action to achieve electrical contact very large 'this will affect the sensitivity and reaction speed of the resistive touch panel' Handwriting and drawing functions that rely on resistive touchpad operation can cause difficulty in operation, disconnection, and discontinuity. Directly using capacitive and resistive superimposed touchpads, there are also many thieves in the product process and M364242 cost control. The first, the way of making money, the manufacturing and cost of the product is not saved by the overlap or the process and cost of the capacitive and resistive two touchpads. At the same time, the two touchpads are combined. Process; the second 'capacitive and resistive touchpad's connection line is still the line of each, and is not simplified because of the overlap, but the number and thickness of the finished line after the finished product has increased - times; third Since there is more than one transmission cable, the connection to the subsequent signal processing module will also need to be redesigned, and the group breaking and routing of the cable will increase the process and cost of the product. Therefore, how to provide a combination of resistive and capacitive touch panels, while the number of layers, thickness and number of wires of the touch panel are not increased, and the sensitivity and light transmittance of the touch panel are not reduced. Many of the multi-sensor touch panels are the goals that the creators are committed to. [New content] In order to solve the above problems in the use of the prior art, the present invention proposes a touch pad for variety of sensing, which can simultaneously have the advantages of both capacitive and resistive touch panels, but only A two-layer structure is required, including: an upper conductive phase and a lower conductive layer. The upper conductive layer further has a plurality of upper sensing portions and a bonding portion connected thereto, and the upper sensing portion is located on a surface of the upper guiding crane; and the upper bonding portion is located at a surface edge of the upper conductive layer . In addition, the lower conductive layer also has a plurality of lower sensing portions and a M364242 electrical sub-joining joint portion, wherein the lower sensing portion is located at a surface edge of the lower guiding edge, and the thin sensing portion touches the guiding portion The upper sensing 邛Μ-疋 distance is relatively established. When the hand is transferred to the office, the _ 鸠 and the lower ke form a capacitance response with the distance of the finger or conductor _, and the electric permeable can pass through the upper joint and the lower The upper portion is slightly measured: the upper portion of the sensing portion is vertically overlapped by the object, and the electric conductive layer is electrically connected to each other by the conductive layer; and the upper engaging portion is at the upper sensing portion or the lower engaging portion. The potential difference formed on the sensing portion generates at least one electrical signal related to the distance of the electrical conduction point. The present invention also proposes a multi-inductive touch panel (secret _钿v kiss 〇f_(4), which can simultaneously have a capacitive The advantages of the resistive touch panel include: an upper conductive layer, a conductive layer, and a lower conductive layer, wherein the upper conductive layer has a plurality of upper sensing portions and is electrically connected thereto. The upper sensing portion is located on the upper conductive The surface is centered; and the upper joint is located at a surface edge of the upper conductive layer, and the conductive layer has a plurality of conductive bridges and the bridge is disposed between any two of the upper sensing portions On the surface, the two upper sensing portions are electrically connected. Further, the lower conductive layer has a conductive film disposed on the surface and a plurality of lower bonding portions electrically connected thereto and located at the edge of the surface. The layer of brittle conductive film and the upper portion of the electrification layer and the conductive bridge are opposite to each other at a certain distance. The M364242 _' portion 212 is above the contact for receiving the contact of the finger or the conductor, and the insulator sheet has The flexibility 'the upper conductive layer is subjected to the surface of the object to generate a partial lower portion; the first sensing portion 212 and the lower sensing portion 222 are in contact with each other to form an electrical conduction. "The electric motor 22 may further include The substrate 224 is located below the plurality of sensing portions 222 to provide a support when the lower conductive layer is pressed. The space between the upper conductive layer 21 and the lower conductive layer 22 may be arranged with a plurality of smoke. Separate li (Spaeer) 3, (10) financial domain transfer, for The electrical connection between the plurality of upper sensing portions and the plurality of lower sensing portions is not received by the _, and the spacer may be a microscopic granular solid structure that is coated on the upper conductive layer and the lower conductive layer, for example: spherical, column The touch condition setting of the shape, the drum shape, and the honeycomb capacitance reaction, and the lower sensation of the microparticles _(4)(10)_, the sensing portion 212 and the lower sensing portion L are force-discharged to allow the upper pass. The micro particles may also be divided into _ ===The fixed part of the electric part 212 and the lower sensing part 222 can be pressed by the fine particles or part of the gorge and the ( (5). This is for different pressing functions. d 111 < In this space, to the present In the first embodiment, the upper sensing object and the upper bonding fine M364242 provide different pressing functions. In the second embodiment of the present invention, the upper sensing portion 212, the upper bonding portion 212, the conductive bridge 23, and the conductive film 223 The arrangement of the lower joint portion 221 is as exemplified in Fig. 5A. The upper sensing portion is a point array leg of a space between the γ-axis symmetry array 以及% and the plurality of yoke arrays 212a, the Y-axis pair _ the end of the column 212a is electrically connected to the lower edge Upper joint portion 211a. The conductive bridge 231 is located between the two axially adjacent arrays 212b and the conductive bridge 231 has an insulating spacer and a C-shaped guide 231a across the two sides of the insulating spacer 231b. The insulating spacer 231b may cover the γ-axis symmetric array 212& and the region interlaced with the c-type guide 231a to isolate the electrical connection between the γ-axis symmetric array arc and the c-plastic guide 231a. The length of the c-type guide 2 can be spanned between the two X-axis adjacent dot arrays (four) so that the two-point array (four) can be electrically conducted through the (four) C-type guide 231a. The conductive bridge 231 can be distributed along the axial direction of the crucible such that the lattice 2b forms a plurality of axisymmetric arrays, and at the same time, the end of the XX axisymmetric array has an extension and the junction portion 211b located above the suppression edge is electrically connection. The conductive film is also electrically connected to the joint 221 below the peripheral edge of the surface. When f is to measure the Wei resistance signal, a voltage difference v is applied to the left lower joint portion 221a and the right lower joint portion (eg, the fifth goblet' when the upper conductive layer is depressed by the pressing pressure, The upper sensing portions 212a, 212b and the conductive bridge 231 near the pressing point M are electrically rolled and electrically connected to the conductive film 223 17 M364242, so that the upper joint portion 211a, 211b and the right lower joint jaw 221b are measured. The voltage 2i22c' can calculate the component of the pressing point A1 on the X-axis from the relationship between the resistance of the upper sensing portion and the conductive film and the distance. When it is necessary, the component of the pressure point A1 on the γ-axis is A voltage difference v is applied to the lower lower joint portion 221c and the lower lower joint portion 221d (as shown in FIG. 5B). When the upper conductive layer is depressed by the pressing force, the upper sensing is performed near the pressing point M. The electrodes 212a, 212b and the conductive bridge 231 are electrically connected to the conductive film 223 to measure the voltage 2i22d between the lower bonding portions 221a, 221b and the lower lower bonding portion 221d. The upper sensing portions 212a, 212b are apart from The above-mentioned single-end connection is used to connect the upper joint portions 211a and 211b, and the two ends may also be used. The ends are connected to the upper joint portions 211a, 211b. At the same time, the position of the upper joint portion is not limited to only the lower side edge or the right side edge. In addition, the arrangement of the upper sensing portion can also be replaced by a symmetrical array arrangement and distribution. The array of dots in between, and the conductive bridges 23ΐ are connected along the axis of the crucible to form a γ-axis symmetric array of the array of points. When the capacitance response signal is required, the sensing unit is touched and the axisymmetric array 212a is measured. The capacitance signal is not electrically connected to the symmetric array (10) of the upper sensing portion (10) as the measurement data of the χaxis component. Similarly, the X-axis symmetric array of the upper sensing portion measures the capacitance signal, and The Y-axis symmetrical array (10) of the upper sensing portion does not make any electrical connection Γ as the measurement data of the Υaxis component. 18 M364242 Since the capacitance reaction signal is expressed in an array manner, it can be used as the continuous resistance response The reference data at the position shortens the procedure for judging the position of the pressing point A1 from the resistance signal, and increases the ability of the creation to respond to the touch touches, so that the lining of the lining can be handwritten in the Wei and Green maps. The performance of the force is more prominent.
