Description

可攜式電子設備、觸摸檢測元件及觸控裝置Portable electronic device, touch detection component and touch device

本發明涉及電子設備設計及製造技術領域,尤其涉及一種觸摸檢測元件、具有所述觸摸檢測元件的觸控裝置以及可攜式電子設備。 The present invention relates to the field of electronic device design and manufacturing technology, and in particular, to a touch detection component, a touch device having the touch detection component, and a portable electronic device.

目前觸摸檢測元件(觸摸屏)在手機,PDA(個人數位助理),GPS(全球定位系統),PMP(MP3,MP4等),甚至平板電腦等電子設備中得到了應用。觸摸屏具有觸控操作簡單、便捷、人性化的優點,因此觸摸屏有望成為人機互動的最佳介面而在可攜式設備中得到了廣泛應用。 At present, touch detection components (touch screens) have been applied in electronic devices such as mobile phones, PDAs (personal digital assistants), GPS (Global Positioning System), PMP (MP3, MP4, etc.), and even tablet computers. The touch screen has the advantages of simple, convenient and user-friendly touch operation, so the touch screen is expected to be the best interface for human-computer interaction and has been widely used in portable devices.

電容觸摸檢測元件通常被分為自電容式和互電容式兩類。現有的單層自電容觸摸屏是在玻璃表面有用ITO(Indium Tin Oxides,納米銦錫金屬氧化物)製成的條形的掃描電極。ITO是一種有固定電阻率的導電物質,其在基材上的一致性比較高,從電阻屏的線性度就可以證明這一點。這些電極和地以及電路等周圍環境構成一個電容的兩極。當用手或觸摸筆觸摸的時候就會並聯一個電容 到電路中去,從而使該條掃描線上的總體電容量有所改變。在掃描的時候,控制IC通過特定的掃描方式掃描各個感應元件,並根據掃描前後的電容變化來確定觸摸點的位置,從而達到人機對話交流。一般情況下電容觸摸屏是和TFT(Thin Film Transistor,薄膜場效應電晶體)LCD一起配對工作,而且是放置在LCD的上面。 Capacitive touch detection components are generally classified into two types: self-capacitance and mutual capacitance. The existing single-layer self-capacitance touch screen is a strip-shaped scan electrode made of ITO (Indium Tin Oxides) on the surface of the glass. ITO is a conductive material with a fixed resistivity, which is relatively uniform on the substrate, as evidenced by the linearity of the resistive screen. These electrodes and the surrounding environment such as the circuit form a pole of a capacitor. When you touch it with your hand or a touch pen, a capacitor is connected in parallel Go to the circuit, so that the overall capacitance of the scan line changes. During scanning, the control IC scans each sensing element by a specific scanning method, and determines the position of the touched point according to the change of capacitance before and after the scanning, thereby achieving human-machine dialogue communication. In general, a capacitive touch screen is paired with a TFT (Thin Film Transistor) LCD and placed on top of the LCD.

第1圖示出了一種傳統自電容式觸摸檢測元件。該自電容式觸摸檢測元件主要有雙層的菱形結構感應單元100’和200’,其檢測原理是對X軸和Y軸分別掃描,如果檢測到某個交叉點的電容變化超出了預設範圍,則將該行和列的交叉點作為觸摸座標。雖然該自電容式觸摸檢測元件的線性度較好,但是經常有鬼點出現,難以實現多點觸摸。此外,由於採用雙層屏,也會導致結構及成本大幅增加,並且菱形結構在電容變化量很小的情況下會出現座標飄移,受外界干擾影響大。 Figure 1 shows a conventional self-capacitive touch detection element. The self-capacitive touch detection component mainly has double-layered diamond-shaped structure sensing units 100' and 200', and the detection principle is to scan the X-axis and the Y-axis separately, if the capacitance change of a certain intersection is detected beyond the preset range , the intersection of the row and column is used as the touch coordinates. Although the linearity of the self-capacitive touch detection element is good, there are often ghost spots, and it is difficult to achieve multi-touch. In addition, due to the use of a double-layer screen, the structure and cost are greatly increased, and the rhombic structure may have coordinate shifts when the amount of capacitance change is small, which is greatly affected by external interference.

第2a圖示出了另一種傳統自電容式觸摸檢測元件。該自電容式觸摸檢測元件採用三角形圖形屏結構。該自電容式觸摸檢測元件包括基板300’、設置在基板300’之上的多個三角形感應單元400’、和每個三角形感應單元400’相連的多個電極500’。第2b圖示出了三角形自電容式觸摸檢測元件的檢測原理。如第2b圖所示,橢圓表示手指,S1、S2表示手指與兩個三角形感應單元的接觸面積。假設座標原點在左下角,則橫坐標X=S2/(S1+S2)*P,其中,P為解析度。當手指向右移動時, 由於S2不是線性增大,所以X座標存在一個偏差。從上述原理可以看出,傳統的三角形感應單元是單端檢測,即只從一個方向檢測,然後通過演算法算出兩個方向的座標。雖然該自電容式觸摸檢測元件結構簡單,但並沒有針對螢幕的電容感應進行優化,電容變化量小,從而導致信噪比不夠。此外,由於該感應單元為三角形,當手指橫向移動時面積不是線性增大,因此線性度較差,導致了座標計算發生偏移,線性度不夠好。 Figure 2a shows another conventional self-capacitive touch detection element. The self-capacitive touch detection element adopts a triangular graphic screen structure. The self-capacitive touch sensing element includes a substrate 300', a plurality of triangular sensing units 400' disposed over the substrate 300', and a plurality of electrodes 500' connected to each of the triangular sensing units 400'. Figure 2b shows the detection principle of a triangular self-capacitive touch detection element. As shown in Fig. 2b, the ellipse represents the finger, and S1, S2 represent the contact area of the finger with the two triangular sensing units. Assuming that the coordinate origin is in the lower left corner, the abscissa X = S2 / (S1 + S2) * P, where P is the resolution. When the finger moves to the right, Since S2 does not increase linearly, there is a deviation in the X coordinate. It can be seen from the above principle that the conventional triangular sensing unit is single-ended detection, that is, detecting only from one direction, and then calculating coordinates in two directions by an algorithm. Although the self-capacitive touch detection element has a simple structure, it is not optimized for the capacitive sensing of the screen, and the capacitance variation is small, resulting in insufficient signal-to-noise ratio. In addition, since the sensing unit is triangular, the area does not increase linearly when the finger moves laterally, so the linearity is poor, resulting in offset calculation of the coordinates, and the linearity is not good enough.

此外,傳統電容感應單元輸出的電容變化量很小,達到飛法級,其電纜雜散電容的存在,對測量電路提出了更高的要求。而且,雜散電容會隨溫度、位置、內外電場分佈等諸多因素影響而變化,干擾甚至淹沒被測電容信號。此外,對於單層電容來說,由於Vcom電平信號的影響會對感應電容形成嚴重的干擾,其中,Vcom電平信號是為了防止LCD螢幕液晶老化而不停翻轉的電平信號。 In addition, the capacitance change of the output of the conventional capacitive sensing unit is small, reaching the flying level, and the existence of the stray capacitance of the cable puts higher requirements on the measuring circuit. Moreover, the stray capacitance will vary with temperature, position, internal and external electric field distribution and other factors, and even interfere with the measured capacitance signal. In addition, for a single-layer capacitor, the influence of the Vcom level signal may cause serious interference to the sensing capacitor, wherein the Vcom level signal is a level signal for preventing the LCD screen from aging and not flipping.

本申請基於發明人對以下事實的認識:傳統的單層自電容觸摸屏的感應元件為雙邊引線的條形。在螢幕的尺寸確定後,該條形的尺寸就基本確定了。條形感應元件的寬度大約為5mm,該寬度變寬會影響線性度,而該寬度窄將會增加通道感應元件。條形的長基本就是觸摸屏的長度。當條形的長寬確定之後,這個條形的兩端之間的電阻就確定了。電阻R=P*L/h,其中,L是感應元件的 長度,h為感應元件的高度,P為ITO的方阻(即,把鍍在基材上面的ITO層做成一個正方形,然後從左邊到右邊的電阻,是ITO基材的一個基本參數)。方阻P的大小和ITO層的厚度有關。而本領域內對ITO方阻只有幾個有限的標準值。由此,當用固定的ITO方阻的基材做成單層自電容觸摸屏後,每條的電阻R可以計算得到。然而,由於檢測手指觸摸的原理是計算電阻的比值,如果電阻R太大或太小都會影響檢測精度,其中參數P是基材決定的,L和h是觸摸屏大小決定的,設計時不能隨意更改,所以如果感應元件做成簡單的條形,電阻往往不是最合適測量的值。 The present application is based on the inventors' knowledge of the fact that the sensing elements of conventional single-layer self-capacitive touch screens are strips of bilateral leads. After the size of the screen is determined, the size of the strip is basically determined. The width of the strip sensing element is approximately 5 mm, which widens the linearity, which narrows the channel sensing element. The length of the strip is basically the length of the touch screen. When the length and width of the strip are determined, the resistance between the ends of the strip is determined. Resistor R=P*L/h, where L is the sensing element The length, h is the height of the sensing element, and P is the square resistance of the ITO (ie, the ITO layer plated on the substrate is made into a square, and then the resistance from the left to the right is a basic parameter of the ITO substrate). The size of the square resistance P is related to the thickness of the ITO layer. There are only a few limited standard values for ITO resistance in the art. Thus, when a substrate having a fixed ITO square resistance is used as a single-layer self-capacitance touch screen, the resistance R of each strip can be calculated. However, since the principle of detecting a finger touch is to calculate the ratio of the resistance, if the resistance R is too large or too small, the detection accuracy is affected, wherein the parameter P is determined by the substrate, and L and h are determined by the size of the touch screen, and cannot be arbitrarily changed during design. Therefore, if the sensing element is made into a simple strip shape, the resistance is often not the most suitable value to measure.

本發明的旨在至少在一定程度上解決上述技術問題之一,尤其是旨在至少解決或避免出現傳統自電容式觸摸檢測元件中的上述缺點之一。 The present invention is intended to solve at least some of the above technical problems, and in particular to at least solve or avoid one of the above disadvantages in conventional self-capacitive touch detection elements.

The current flowing between the 22 through the current path portion 25 is used to charge the self-capacitance generated when the current is sensed by the current to the sensing body 20, and is used to calculate at least when the sensing body 20 of the at least one sensing unit 2 is detected to be touched. a proportional relationship between a first resistance between the first electrode 21 and the self-capacitance of the sensing unit 2 and a second resistance between the second electrode 22 of the at least one sensing unit 2 and the self-capacitance, and is used according to the first Resistance and second electricity The proportional relationship between the resistances determines the touch position at which the sensing body 20 of the at least one sensing unit 2 is touched.

具體地,第一電阻和第二電阻之間的比例關係根據在對自電容充電/放電時,從第一電極及/或第二電極進行檢測獲得的第一檢測值和第二檢測值之間的比例關係計算得到,如上所述對第一電極和第二電極的充電、放電或檢測可同時進行,也可分開進行。當觸摸檢測元件控制晶片200根據第一檢測值和第二檢測值確定對應的感應單元被觸摸時,則觸摸檢測元件控制晶片200根據第一檢測值和第二檢測值計算第一電阻和第二電阻的比例關係,從而進一步判斷在第一方向上的觸摸位置,並根據對應的感應單元2的位置確定在第二方向上的觸摸位置。最後觸摸檢測元件控制晶片200根據第一方向上的觸摸位置和第二方向上的觸摸位置就可確定觸摸點在觸摸檢測元件上的位置。在此還需要說明的是,在本發明的實施例中對於對感應單元的充電和放電次序來說沒有限制,例如在一個實施例中,可以以掃描的方式對所有的感應單元2依次進行充電,接著再依次地對其進行放電檢測;在另一個實施例中,可以逐個對感應單元2進行充電和放電,例如對一個感應單元2充電之後,接著就對其進行放電檢測,對該感應單元2處理完成之後,再對下一個感應單元2進行處理。在本發明的一個實施例中,觸摸檢 測元件控制晶片200向感應單元2的第一電極21和第二電極22施加電平信號以對自電容充電,觸摸檢測元件控制晶片200從第一電極21及/或第二電極22進行充電檢測以獲得第一充電檢測值和第二充電檢測值。 Specifically, a proportional relationship between the first resistance and the second resistance is between a first detection value and a second detection value obtained by detecting the first electrode and/or the second electrode when charging/discharging the self capacitance The proportional relationship is calculated, and the charging, discharging or detecting of the first electrode and the second electrode may be performed simultaneously as described above, or may be performed separately. When the touch detection element control wafer 200 determines that the corresponding sensing unit is touched according to the first detection value and the second detection value, the touch detection element control wafer 200 calculates the first resistance and the second according to the first detection value and the second detection value. The proportional relationship of the resistances further determines the touch position in the first direction, and determines the touch position in the second direction according to the position of the corresponding sensing unit 2. Finally, the touch detecting element controls the wafer 200 to determine the position of the touch point on the touch detecting element according to the touch position in the first direction and the touch position in the second direction. It should also be noted here that there is no limitation on the order of charging and discharging the sensing unit in the embodiment of the present invention. For example, in one embodiment, all the sensing units 2 can be sequentially charged in a scanning manner. And then, in turn, discharge detection is performed; in another embodiment, the sensing unit 2 can be charged and discharged one by one, for example, after charging one sensing unit 2, and then discharging is detected, the sensing unit is 2 After the processing is completed, the next sensing unit 2 is processed. In one embodiment of the invention, touch detection The measuring element control wafer 200 applies a level signal to the first electrode 21 and the second electrode 22 of the sensing unit 2 to charge the self-capacitance, and the touch detecting element controls the wafer 200 to perform charging detection from the first electrode 21 and/or the second electrode 22. A first charge detection value and a second charge detection value are obtained.

具體地,本發明實施例的觸控裝置採用新穎的自電容式檢測方式,在感應單元被觸摸時,在感應單元的觸摸點處產生自電容,且觸摸點可以將感應單元分為兩個電阻,在進行自電容檢測的同時考慮這兩個電阻就可以確定觸摸點在該感應單元上的位置。第3圖為本發明實施例的觸控裝置的檢測原理示意圖。當手指300觸摸感應單元時,將相當於將感應單元分割為第一和第二兩個電阻R1、R2,第一電阻R1和第二電阻R2的阻值之間的比例關係與觸摸點的位置相關。例如,如第3圖所示,當觸摸點與第一電極21較近時,則第一電阻R1就較小,而第二電阻R2就較大;反之,當觸摸點與第二電極22較近時,則第一電阻R1就較大,而第二電阻R2就較小。因此,通過對第一電阻R1和第二電阻R2的檢測就可以確定觸摸點在感應單元2上的位置。 Specifically, the touch device of the embodiment of the invention adopts a novel self-capacitance detection mode, and when the sensing unit is touched, a self-capacitance is generated at a touch point of the sensing unit, and the touch point can divide the sensing unit into two resistors. Considering these two resistors while performing self-capacitance detection, the position of the touch point on the sensing unit can be determined. FIG. 3 is a schematic diagram of a detection principle of a touch device according to an embodiment of the invention. When the finger 300 touches the sensing unit, it is equivalent to dividing the sensing unit into the first and second two resistors R1 and R2, and the proportional relationship between the resistance values of the first resistor R1 and the second resistor R2 and the position of the touch point. Related. For example, as shown in FIG. 3, when the touch point is closer to the first electrode 21, the first resistor R1 is smaller, and the second resistor R2 is larger; otherwise, when the touch point is compared with the second electrode 22 In the near moment, the first resistor R1 is larger, and the second resistor R2 is smaller. Therefore, the position of the touch point on the sensing unit 2 can be determined by detecting the first resistor R1 and the second resistor R2.

在本發明的實施例中,可通過多種方式檢測第一電阻R1和第二電阻R2的電阻值,例如可通過電流的檢測值、自電容的檢測值、自電容的電平信號的檢測值和自電容的電荷變化量檢測值中的一種或多種,從而根據 這些檢測值獲得第一電阻R1和第二電阻R2。另外,在本發明的實施例中,上述檢測值的檢測可在對自電容充電時進行(即獲得第一充電檢測值和第二充電檢測值),也可在自電容放電時進行(即獲得第一放電檢測值和第二放電檢測值)。此外,在充電和放電時進行的檢測可以採用多種方式。 In the embodiment of the present invention, the resistance values of the first resistor R1 and the second resistor R2 can be detected in various manners, for example, the detected value of the current, the detected value of the self-capacitance, the detected value of the self-capacitance level signal, and One or more of the self-capacitance charge change detection values, thereby These detected values obtain the first resistor R1 and the second resistor R2. In addition, in the embodiment of the present invention, the detection of the detection value may be performed when charging the self-capacitance (ie, obtaining the first charging detection value and the second charging detection value), or may be performed during self-capacitance discharging (ie, obtaining The first discharge detection value and the second discharge detection value). In addition, the detection performed during charging and discharging can be performed in various ways.

需要說明的是,充電和放電中的至少一個是從第一電極21和第二電極22進行的,從而能夠獲得反應第一電阻和第二電阻之間差值的兩個檢測值,即第一檢測值和第二檢測值。也就是說,在充電或放電時需要有電流經過第一電阻R1和第二電阻R2,從而檢測到的第一檢測值和第二檢測值可以反應第一電阻R1和第二電阻R2之間的差值。 It should be noted that at least one of charging and discharging is performed from the first electrode 21 and the second electrode 22, so that two detection values of the difference between the first resistance and the second resistance can be obtained, that is, the first The detected value and the second detected value. That is, a current is required to pass through the first resistor R1 and the second resistor R2 during charging or discharging, so that the detected first detection value and second detection value may reflect between the first resistor R1 and the second resistor R2. Difference.

在本發明的實施例中,通常需要充兩次電以及進行兩次檢測,充電包括同時從第一電極21和第二電極22充電的情況。在一些實施例中,還可以進行兩次放電。為了方便起見,在以下的實施例中均是進行兩次充電及兩次檢測。需要說明的是,進行兩次充電及兩次檢測僅是本發明實施例的一種方案,演算法相對比較簡單。然而本領域技術人員也可根據上述思想增加充電及檢測的次數,例如可進行三次充電和檢測,之後根據第一次的充電檢測值和第二次的充電檢測值計算第一電阻R1,再根據 第一次的充電檢測值和第三次的充電檢測值計算第二電阻R2。 In an embodiment of the invention, it is generally necessary to charge twice and perform two tests, the charging including the simultaneous charging of the first electrode 21 and the second electrode 22. In some embodiments, two discharges can also be performed. For the sake of convenience, in the following examples, two charges and two tests were performed. It should be noted that performing two charging and two detecting is only one solution of the embodiment of the present invention, and the algorithm is relatively simple. However, those skilled in the art can also increase the number of times of charging and detecting according to the above idea, for example, three times charging and detecting can be performed, and then calculating the first resistor R1 according to the first charging detection value and the second charging detection value, and then according to The second charge detection value and the third charge detection value calculate the second resistance R2.

具體地,根據本發明的實施例包括但不限於以下幾種具體測量方式進行檢測: Specifically, embodiments according to the present invention include, but are not limited to, the following specific measurement methods for detection:

1、先向感應單元的第一電極21和第二電極22施加電平信號以對自電容充電(所述自電容在感應單元被觸摸產生);接著從第一電極21及/或第二電極22進行充電和檢測以獲得第一充電檢測值和第二充電檢測值。在該實施例中,由於充電是從第一電極21和第二電極22進行的,因此檢測可以從第一電極21進行檢測,也可以從第二電極22進行檢測,或者從第一電極21和第二電極22分別進行檢測。還需要說明的是,在該實施例中,從第一電極21和第二電極22的充電可同時進行,也可分別單獨進行,例如對第一電極21和第二電極22同時施加相同的電平信號以對自電容進行充電,在其他實施例中,對第一電極21和第二電極22施加的電平信號也可以不同;或者,也可以先在第一電極21上施加一個電平信號,之後再在第二電極22上施加相同的電平信號或不同的電平信號。同樣地,從第一電極21和第二電極22的檢測可以同時進行,也可分別進行。在下面的實施例中,檢測與充電可以同時進行,或者分別進行。 1. First applying a level signal to the first electrode 21 and the second electrode 22 of the sensing unit to charge the self-capacitor (the self-capacitance is generated by the sensing unit being touched); then from the first electrode 21 and/or the second electrode 22 performs charging and detecting to obtain a first charging detection value and a second charging detection value. In this embodiment, since charging is performed from the first electrode 21 and the second electrode 22, the detection may be detected from the first electrode 21, or may be detected from the second electrode 22, or from the first electrode 21 and The second electrodes 22 are respectively detected. It should be noted that, in this embodiment, the charging from the first electrode 21 and the second electrode 22 may be performed simultaneously, or separately, for example, the first electrode 21 and the second electrode 22 are simultaneously applied with the same electric power. The flat signal charges the self-capacitance. In other embodiments, the level signals applied to the first electrode 21 and the second electrode 22 may also be different; or, a level signal may be applied to the first electrode 21 first. Then, the same level signal or a different level signal is applied to the second electrode 22. Similarly, the detection from the first electrode 21 and the second electrode 22 may be performed simultaneously or separately. In the following embodiments, the detection and charging may be performed simultaneously or separately.

2、向感應單元的第一電極21或第二電極22分兩次施加電平信號以對自電容進行兩次充電;在每次充電之後從第一電極21及/或第二電極22進行檢測以獲得第一充電檢測值和第二充電檢測值。在該實施例中,由於充電是從第一電極21或第二電極22進行的,因此檢測需要從第一電極21和第二電極22分別進行,其中,從第一電極21和第二電極22的檢測可同時進行,也可分別進行。此外,可選地,還可以在第一電極21進行兩次充電,並從第一電極21進行兩次檢測,或者,從第二電極22進行兩次充電,在第二電極22進行兩次檢測。在從一個電極兩次充電時,分別將另一個電極接地或接高阻以改變另一個電極的狀態。例如當向感應單元的第一電極21分別兩次施加電平信號以對自電容進行兩次充電時,其中,兩次充電中的一次充電過程中將所述第二電極22接地,另一次充電過程中將所述第二電極22接為高阻;當向感應單元的第二電極22分別兩次施加電平信號以對自電容進行兩次充電時,兩次充電中的一次充電過程中將所述第一電極21接地,另一次充電過程中將所述第一電極21接為高阻。這樣即使是在第一電極21進行了兩次充電,由於第二電極22狀態的改變,也能夠在第一電極21進行兩次檢測,以獲得能夠反應第一電阻R1和第二電阻R2之間比例關係的第一檢測值和第二檢測值。 2. Applying a level signal to the first electrode 21 or the second electrode 22 of the sensing unit twice to charge the self-capacitor twice; detecting from the first electrode 21 and/or the second electrode 22 after each charging A first charge detection value and a second charge detection value are obtained. In this embodiment, since charging is performed from the first electrode 21 or the second electrode 22, detection is required to be performed from the first electrode 21 and the second electrode 22, respectively, from the first electrode 21 and the second electrode 22 The detection can be performed simultaneously or separately. Further, alternatively, it is also possible to perform charging twice at the first electrode 21 and two times from the first electrode 21, or two times from the second electrode 22, and two times at the second electrode 22. . When charging from one electrode twice, the other electrode is grounded or connected to a high resistance to change the state of the other electrode. For example, when a level signal is applied to the first electrode 21 of the sensing unit twice to charge the self-capacitor twice, wherein the second electrode 22 is grounded during one charging of the two charging, and another charging is performed. The second electrode 22 is connected to a high resistance during the process; when a level signal is applied twice to the second electrode 22 of the sensing unit to charge the self-capacitor twice, one of the two charging processes will be performed. The first electrode 21 is grounded, and the first electrode 21 is connected to a high resistance during another charging process. Thus, even if the first electrode 21 is charged twice, since the state of the second electrode 22 is changed, it is possible to perform two detections at the first electrode 21 to obtain a reaction between the first resistor R1 and the second resistor R2. The first detected value and the second detected value of the proportional relationship.

3、向感應單元的第一電極21和第二電極22施加電平信號以對自電容充電;接著控制第一電極21及/或第二電極22接地以對自電容放電;之後從第一電極21及/或第二電極22進行放電檢測以獲得所述第一放電檢測值和第二放電檢測值。在該實施例中,由於對自電容充電是從第一電極21和第二電極22進行的,因此放電或檢測就可從第一電極21及/或第二電極22進行。具體地,例如可同時向第一電極21和第二電極22施加電平信號以對自電容進行充電,或者也可不同時施加電平信號。在兩次放電時可均將第一電極21接地,或者均將第二電極22接地。 3. Applying a level signal to the first electrode 21 and the second electrode 22 of the sensing unit to charge the self-capacitor; then controlling the first electrode 21 and/or the second electrode 22 to be grounded to discharge the self-capacitance; thereafter, from the first electrode 21 and/or the second electrode 22 performs discharge detection to obtain the first discharge detection value and the second discharge detection value. In this embodiment, since the self-capacitance is charged from the first electrode 21 and the second electrode 22, discharge or detection can be performed from the first electrode 21 and/or the second electrode 22. Specifically, for example, a level signal may be simultaneously applied to the first electrode 21 and the second electrode 22 to charge the self capacitance, or a level signal may not be applied at the same time. The first electrode 21 may be grounded at both discharges, or both of the second electrode 22 may be grounded.

4、向感應單元的第一電極21或第二電極22施加電平信號以對自電容充電;接著分別控制第一電極21和第二電極22接地以對自電容放電;之後分別從第一電極21及/或第二電極22進行放電檢測以獲得第一放電檢測值和第二放電檢測值。在該實施例中,由於對自電容放電是從第一電極21和第二電極22進行的,因此充電或檢測就可從第一電極21及/或第二電極22進行。在該實施例中,兩次充電也可均從第一電極21進行,而將第二電極22分別接地或接為高阻。同樣地,兩次充電也可均從第二電極22進行,而將第一電極21分別接地或接為高阻。 4. Applying a level signal to the first electrode 21 or the second electrode 22 of the sensing unit to charge the self-capacitor; then controlling the first electrode 21 and the second electrode 22 to ground respectively to discharge the self-capacitance; respectively, respectively, from the first electrode 21 and/or the second electrode 22 performs discharge detection to obtain a first discharge detection value and a second discharge detection value. In this embodiment, since the self-capacitance discharge is performed from the first electrode 21 and the second electrode 22, charging or detecting can be performed from the first electrode 21 and/or the second electrode 22. In this embodiment, both charges may also be performed from the first electrode 21, and the second electrode 22 may be grounded or connected to a high resistance, respectively. Similarly, both charges may be performed from the second electrode 22, and the first electrodes 21 may be grounded or connected to a high resistance, respectively.

5、向感應單元的第一電極21或第二電極22施加電平信號以對自電容充電;接著分別控制第一電極21或第二電極22接地以對自電容放電,之後分別從第一電極21和第二電極22進行放電檢測以獲得第一放電檢測值和第二放電檢測值。在該實施例中,由於對自電容檢測是從第一電極21和第二電極22進行的,因此充電或放電可從第一電極21及/或第二電極22進行。在該實施例中,兩次充電也可均從第一電極21進行,而將第二電極22分別接地或接為高阻。同樣地,兩次充電也可均從第二電極22進行,而將第一電極21分別接地或接為高阻。 5. Apply a level signal to the first electrode 21 or the second electrode 22 of the sensing unit to charge the self-capacitor; then respectively control the first electrode 21 or the second electrode 22 to ground to discharge the self-capacitance, and then respectively from the first electrode 21 and the second electrode 22 perform discharge detection to obtain a first discharge detection value and a second discharge detection value. In this embodiment, since the self-capacitance detection is performed from the first electrode 21 and the second electrode 22, charging or discharging can be performed from the first electrode 21 and/or the second electrode 22. In this embodiment, both charges may also be performed from the first electrode 21, and the second electrode 22 may be grounded or connected to a high resistance, respectively. Similarly, both charges may be performed from the second electrode 22, and the first electrodes 21 may be grounded or connected to a high resistance, respectively.

或者,在上述實施例的基礎之上,還可以在充電時進行一次檢測以獲得第一充電檢測值,在放電時進行第二次檢測以獲得第二放電檢測值,再根據第一充電檢測值和第二放電檢測值獲得第一電阻R1和第二電阻R2之間的比例關係。 Alternatively, on the basis of the above embodiment, one detection may be performed at the time of charging to obtain a first charging detection value, and a second detection is performed at the time of discharging to obtain a second discharging detection value, and then according to the first charging detection value. And the second discharge detection value obtains a proportional relationship between the first resistor R1 and the second resistor R2.

需要說明的是,在本發明的實施例中,上述第一電極21和第二電極22的功能相同,且二者可以互換,因此在上述實施例中,既可以從第一電極21檢測也可以從第二電極22檢測,只要能滿足在檢測時有電流經過第一電阻R1和第二電阻R2即可。 It should be noted that, in the embodiment of the present invention, the functions of the first electrode 21 and the second electrode 22 are the same, and the two are interchangeable. Therefore, in the above embodiment, the first electrode 21 may be detected or may be It is detected from the second electrode 22 that a current can pass through the first resistor R1 and the second resistor R2 at the time of detection.

從上述描述中可以看出,對於本發明實施例的上述充電及檢測方式有很多種變化,但本發明的實施例 在於根據第一電阻R1和第二電阻R2之間的關係,例如比例關係或者其他關係來確定觸摸點的位置。進一步地,第一電阻R1和第二電阻R2之間的關係需要通過自電容的充電及/或放電進行檢測。如果感應單元沒有被觸摸,則就不會與手產生自電容,因此檢測到自電容的資料會很小,不滿足觸摸的判斷條件,對於此,在本發明的實施例中會不斷掃描,等待手指300觸摸到感應單元之後才開始計算,在此不再贅述。 As can be seen from the above description, there are many variations on the above charging and detecting methods for the embodiments of the present invention, but embodiments of the present invention The position of the touched point is determined according to a relationship between the first resistor R1 and the second resistor R2, such as a proportional relationship or other relationship. Further, the relationship between the first resistor R1 and the second resistor R2 needs to be detected by charging and/or discharging of the self capacitor. If the sensing unit is not touched, the self-capacitance is not generated with the hand, so the data of the self-capacitance is detected to be small, and the judgment condition of the touch is not satisfied. For this, in the embodiment of the present invention, the scanning is continuously performed, waiting The calculation is started after the finger 300 touches the sensing unit, and details are not described herein again.

在本發明的實施例中,可以以掃描的方式依次向多個感應單元施加相應的電壓,同時在檢測時也可以以掃描的方式依次進行檢測。 In the embodiment of the present invention, the corresponding voltages may be sequentially applied to the plurality of sensing units in a scanning manner, and may also be sequentially detected in a scanning manner during the detection.

另外還需要說明的是,上述檢測方式僅為本發明實施例的一些優選方式,本領域技術人員還可根據上述思想進行擴展、修改和變型。 It should be noted that the foregoing detection manners are only some preferred manners of the embodiments of the present invention, and those skilled in the art may also expand, modify, and modify according to the above ideas.

第4圖為本發明實施例的觸控裝置的觸摸檢測方法流程圖,下面結合第3圖所示的原理圖一同進行說明。觸摸檢測方法包括以下步驟: FIG. 4 is a flow chart of a touch detection method of a touch device according to an embodiment of the present invention, which will be described below in conjunction with the schematic diagram shown in FIG. 3. The touch detection method includes the following steps:

步驟S401,向感應單元的兩端施加電平信號,即向感應單元的第一電極21及/或第二電極22施加電平信號。在該實施例中,可向第一電極21和第二電極22施加相同的電平信號,也可施加不同的電平信號。在其他實施例中,也可僅從第一電極21或第二電極22進行 充電兩次,或者第一次從第一電極21充電第二次從第二電極22充電,或者第一次從第二電極22充電第二次從第一電極21充電。 In step S401, a level signal is applied to both ends of the sensing unit, that is, a level signal is applied to the first electrode 21 and/or the second electrode 22 of the sensing unit. In this embodiment, the same level signal may be applied to the first electrode 21 and the second electrode 22, and different level signals may be applied. In other embodiments, it may also be performed only from the first electrode 21 or the second electrode 22. Charging twice, or charging the second electrode 22 a second time from the first electrode 21 for the first time, or charging the first electrode 21 a second time from the second electrode 22 for the first time.

如果此時感應單元被手指或其他物體觸摸,則該感應單元將會產生自電容C1(參照第3圖),通過施加的電平信號就可對自電容進行充電。在本發明的實施例中,通過對自電容的充電,可以提高自電容的檢測精度。需要說明的是,如果向感應單元的兩端同時施加電平信號的話,則需要相應的兩個電容檢測模組CTS同時從第一電極21和第二電極22進行檢測。而如果分別向感應單元的兩端施加的話,則僅需要一個電容檢測模組CTS即可。在本發明的一個實施例中,第一檢測值和第二檢測值可以為從第一電極21及/或第二電極22檢測到的電容電荷變化量△Q1和△Q2。通過△Q1與△Q2,即檢測到得自電容的電荷變化量,就可以算出電阻R1與R2的比例,從而可以算出觸摸點所在的橫坐標的位置,及自電容C1所在的位置。 If the sensing unit is touched by a finger or other object at this time, the sensing unit will generate a self-capacitance C1 (refer to FIG. 3), and the self-capacitance can be charged by the applied level signal. In the embodiment of the present invention, the detection accuracy of the self-capacitance can be improved by charging the self-capacitance. It should be noted that if a level signal is simultaneously applied to both ends of the sensing unit, the corresponding two capacitance detecting modules CTS are required to be simultaneously detected from the first electrode 21 and the second electrode 22. If it is applied to both ends of the sensing unit, only one capacitance detecting module CTS is needed. In one embodiment of the present invention, the first detected value and the second detected value may be capacitance charge variations ΔQ1 and ΔQ2 detected from the first electrode 21 and/or the second electrode 22. By ΔQ1 and ΔQ2, that is, the amount of charge change from the capacitance is detected, the ratio of the resistance R1 to R2 can be calculated, and the position of the abscissa where the touch point is located and the position where the self-capacitance C1 is located can be calculated.

步驟S402,從感應單元的兩端對感應單元進行檢測,以獲得第一檢測值和第二檢測值。在該實施例中,檢測可在充電時進行,也可在放電時進行。在上述例子中,第一檢測值和第二檢測值分別為△Q1和△Q2。以下以第一檢測值和第二檢測值為電荷變化量為例進行描 述,但是能夠反應第一電阻R1和第二電阻R2關係的其他檢測值,例如電平信號、電流等也均可採用。在本發明的實施例中,從第一電極21和第二電極22進行的檢測可以同時進行,也可以分別進行。 Step S402, detecting the sensing unit from both ends of the sensing unit to obtain a first detection value and a second detection value. In this embodiment, the detection may be performed while charging or during discharging. In the above example, the first detected value and the second detected value are ΔQ1 and ΔQ2, respectively. The following takes the first detection value and the second detection value as the charge change amount as an example. However, other detected values that can reflect the relationship between the first resistor R1 and the second resistor R2, such as a level signal, a current, etc., can also be employed. In the embodiment of the present invention, the detection from the first electrode 21 and the second electrode 22 may be performed simultaneously or separately.

在本發明的一個實施例中,如果檢測同時進行,則需要兩個電容檢測模組CTS同時對第一電極21和第二電極22進行檢測,因此所述控制晶片包括一個或兩個電容檢測模組CTS。 In one embodiment of the present invention, if the detection is performed simultaneously, two capacitance detecting modules CTS are required to simultaneously detect the first electrode 21 and the second electrode 22, so the control wafer includes one or two capacitance detecting modes. Group CTS.

在本發明的另一個實施例中,也可採用一個電容檢測模組CTS進行檢測,參照步驟S401中,在通過第一電極21對自電容C1充滿之後,即該電容檢測模組CTS通過第一電極21對自電容C1進行檢測。接著再通過第二電極22對自電容C2充電,接著該電容檢測模組CTS再通過第二電極22對自電容C1進行檢測。 In another embodiment of the present invention, a capacitance detecting module CTS can also be used for detecting. Referring to step S401, after the self-capacitance C1 is filled by the first electrode 21, the capacitance detecting module CTS passes the first The electrode 21 detects the self capacitance C1. Then, the self-capacitance C2 is charged by the second electrode 22, and then the capacitance detecting module CTS detects the self-capacitance C1 through the second electrode 22.

由於控制晶片掃描該感應單元時採用的相位和電平信號均一致,因此對於同一個自電容C1來說充電時的電荷就等於它們電阻的反比。假設,從感應單元的第一電極21和第二電極22對感應單元檢測獲得的電荷變化量分別是△Q1與△Q2。在本發明的實施例中,電容檢測模組CTS可為目前已知的電容檢測模組CTS。在本發明的一個實施例中,如果採用兩個電容檢測模組CTS的話, 則由於兩個電容檢測模組CTS可共用多個器件,因此不會增大控制晶片的整體功耗。 Since the control chip scans the sensing unit with the same phase and level signals, the charge when charging the same self-capacitance C1 is equal to the inverse of their resistance. It is assumed that the amount of change in charge obtained by detecting the sensing unit from the first electrode 21 and the second electrode 22 of the sensing unit is ΔQ1 and ΔQ2, respectively. In the embodiment of the present invention, the capacitance detecting module CTS can be a currently known capacitance detecting module CTS. In an embodiment of the present invention, if two capacitance detecting modules CTS are used, Since the two capacitance detecting modules CTS can share a plurality of devices, the overall power consumption of the control chip is not increased.

步驟S403,根據第一檢測值和第二檢測值判斷該感應單元是否被觸摸。具體地,在本發明的一個實施例中,可通過判斷電荷變化量△Q1與△Q2是否大於閾值來確定是否被觸摸。當然,在本發明的其他實施例中,還可設置其他判斷方式,例如判斷電荷變化量△Q1與△Q2是否小於閾值,如果小於,則判斷感應單元被觸摸。同樣地,該閾值也需要根據觸摸檢測元件的大小和類型,感應單元的尺寸確定。 Step S403, determining whether the sensing unit is touched according to the first detection value and the second detection value. Specifically, in one embodiment of the present invention, whether or not the touch is touched can be determined by judging whether or not the charge change amounts ΔQ1 and ΔQ2 are greater than a threshold. Of course, in other embodiments of the present invention, other manners of determining may be set, such as determining whether the amount of charge change ΔQ1 and ΔQ2 is less than a threshold, and if so, determining that the sensing unit is touched. Similarly, the threshold also needs to be determined according to the size and type of the touch detecting element, and the size of the sensing unit.

步驟S404,如果判斷該感應單元被觸摸,則此時進一步計算相應的感應單元中所述第一電極21和所述自電容間的第一電阻與所述第二電極22和所述自電容間的第二電阻之間的比例關係。並根據第一電阻和所述第二電阻之間的比例關係確定觸摸物體(例如手指)的觸摸位置。在本發明的實施例中,第一電阻和所述第二電阻之間的比例關係根據在對自電容充電/放電時,從第一電極21及/或第二電極22進行檢測獲得的第一檢測值和第二檢測值之間的比例關係計算得到。同上,C1所在的感應單元上的座標即為△Q2/(△Q1+△Q2)。 Step S404, if it is determined that the sensing unit is touched, then further calculating a first resistance between the first electrode 21 and the self-capacitance in the corresponding sensing unit and the second electrode 22 and the self-capacitance The proportional relationship between the second resistors. And determining a touch position of the touch object (eg, a finger) according to a proportional relationship between the first resistance and the second resistance. In an embodiment of the invention, the proportional relationship between the first resistance and the second resistance is the first obtained by detecting from the first electrode 21 and/or the second electrode 22 when charging/discharging the self-capacitance The proportional relationship between the detected value and the second detected value is calculated. As above, the coordinate on the sensing unit where C1 is located is ΔQ2/(ΔQ1+△Q2).

在本發明的實施例中,如果感應單元的感應本體為大體U形或大體L形,則通過第一電阻和第二電 阻之間的比值就可確定在感應本體上的觸摸位置,以下將結合具體的例子進行詳述。但在本發明的其他實施例中,如果感應本體為大體矩形,則步驟S404只能計算出在感應單元的感應本體上的第一方向上的觸摸位置,該第一方向可以是感應本體的長度方向(例如感應單元的水準方向)。 In an embodiment of the invention, if the sensing body of the sensing unit is substantially U-shaped or substantially L-shaped, passing through the first resistor and the second battery The ratio between the resistances determines the position of the touch on the sensing body, as will be described in more detail below in connection with specific examples. However, in other embodiments of the present invention, if the sensing body is substantially rectangular, step S404 can only calculate the touch position in the first direction on the sensing body of the sensing unit, and the first direction can be the length of the sensing body. Direction (for example, the level of the sensing unit).

如果感應本體為矩形,則還需要確定在第二方向上的觸摸位置。在本發明的一個實施例中,第一方向為感應本體的長度方向,第二方向為垂直於第一方向的方向,感應本體水準設置或垂直設置。 If the sensing body is rectangular, it is also necessary to determine the touch position in the second direction. In an embodiment of the invention, the first direction is the length direction of the sensing body, and the second direction is a direction perpendicular to the first direction, and the sensing body level setting or vertical setting.

具體地,可採用質心算法計算觸摸點在第二方向上的觸摸位置,以下對質心算法進行簡單介紹。 Specifically, the centroid algorithm can be used to calculate the touch position of the touch point in the second direction. The following describes the centroid algorithm briefly.

在滑條和觸摸板應用中,經常需要在具體感應單元的本質間距以上確定出手指(或其他電容性物體)的位置。手指在滑條或觸摸板上的接觸面積通常大於任何個感應單元。為了採用一個中心來計算觸摸後的位置,對這個陣列進行掃描以驗證所給定的感測器位置是有效的,對於一定數量的相鄰感應單元信號的要求是要大於預設觸摸閾值。在找到最為強烈的信號後,此信號和那些大於觸摸閾值的臨近信號均用於計算中心: In slider and touchpad applications, it is often desirable to determine the position of a finger (or other capacitive object) above the intrinsic spacing of a particular sensing unit. The contact area of the finger on the slider or touchpad is usually larger than any of the sensing units. In order to use a center to calculate the position after the touch, the array is scanned to verify that the given sensor position is valid, and the requirement for a certain number of adjacent sensing unit signals is greater than the preset touch threshold. After finding the strongest signal, this signal and those adjacent to the touch threshold are used in the calculation center: In slider and touchpad applications, it is often desirable to determine the position of a finger (or other capacitive object) above the intrinsic spacing of a particular sensing unit. The contact area of ​​the finger on the slider or touchpad is usually larger than any of the sensing units. In order to use a center to calculate the position after the touch, the array is scanned to verify that the given sensor position is valid, and the requirement for a certain number of adjacent sensing unit signals is greater than the preset touch threshold. After finding the strongest signal, this signal and those adjacent to the touch threshold are used in the calculation center:

其中,N Cent為中心處感應單元的標號,n為檢測到被觸摸的感應單元的個數,i為被觸摸感應單元的序號,其中i大於等於2。 Where N Cent is the label of the sensing unit at the center, n is the number of sensing units that are touched, and i is the serial number of the touched sensing unit, where i is greater than or equal to 2.

例如,當手指觸摸在第一條通道,其電容變化量為y1,第二條通道上的電容變化量為y2和第三條通道上的電容變化量為y3時。其中第二通道y2電容變化量最大。Y座標就可以算是: 例如,當手指觸摸在第一條通道,其電容變化量為y1,第二條通道上的電容變化量為y2和第三條通道上的電容變化量為y3時。其中第二通道y2電容變化量最大。Y座標就可以算是: For example, when the finger touches the first channel, the capacitance change amount is y1, the capacitance change amount on the second channel is y2, and the capacitance change amount on the third channel is y3. The second channel y2 capacitance changes the most. The Y coordinate can be regarded as: For example, when the finger touches the first channel, the capacitance change amount is y1, the capacitance change amount on the second channel is y2, and the capacitance change amount on the third channel is y3. The second channel y2 capacitance changes the most. The Y coordinate can be regarded as:

本發明第一方面的實施例根據上述思想提出了一種觸摸檢測元件。下面參考第6-41圖描述根據本發明實施例的觸摸檢測元件100。 The embodiment of the first aspect of the present invention proposes a touch detecting element in accordance with the above idea. The touch detecting element 100 according to an embodiment of the present invention is described below with reference to FIGS. 6-41.

根據本發明實施例的觸摸檢測元件100包括:基板1和多個感應單元2。其中多個感應單元2設在基板1上且彼此不相交。在本發明的實施例中,優選地,不相交的感應單元2之間可以相互平行。可選地,不相交的感應單元2之間也可以部分地平行,但至少在基板1上感應單元2彼此不相交。但是在此需要說明的是,對於多個感應單元2來說,並不限於第5圖所示的結構,感應單元2還可採用其他的結構,例如感應單元2的一部分或全部具有一定的弧度等,這些均可應用在本發明中。 The touch detecting element 100 according to an embodiment of the present invention includes a substrate 1 and a plurality of sensing units 2. A plurality of sensing units 2 are disposed on the substrate 1 and do not intersect each other. In an embodiment of the invention, preferably, the disjoint sensing units 2 may be parallel to each other. Alternatively, the disjoint sensing units 2 may also be partially parallel, but at least on the substrate 1 the sensing units 2 do not intersect each other. However, it should be noted that, for the plurality of sensing units 2, the structure shown in FIG. 5 is not limited, and the sensing unit 2 may adopt other structures, for example, part or all of the sensing unit 2 has a certain curvature. Etc., these can be applied to the present invention.

可選地,基板1為大體矩形。這裡“大體矩形”應理解為基板1的相對邊可以部絕對平行,例如可以成一個小的角度,並且基板1的每個邊可以不是絕對的直。每個感應單元2包括感應本體20以及分別與感應本體20相連的第一電極21和第二電極22。第一電極21和第二電極22分別與控制晶片200的對應的管腳相連。感應本體20具有多個鏤空部24,多個鏤空部24以預定規則排列以在感應本體20上限定出用於增大第一電極21和第二電極22之間的電阻R的電流通路部25,該電流通路部25用於電流的行走。優選地,鏤空部24沿感應本體20的厚度方向貫通,由於感應本體20的厚度比較小,鏤空部24貫通感應本體20便於製作和生產。 Optionally, the substrate 1 is generally rectangular. Here, "substantially rectangular" is understood to mean that the opposite sides of the substrate 1 may be absolutely parallel, for example, may be at a small angle, and each side of the substrate 1 may not be absolutely straight. Each of the sensing units 2 includes an inductive body 20 and a first electrode 21 and a second electrode 22 connected to the inductive body 20, respectively. The first electrode 21 and the second electrode 22 are respectively connected to corresponding pins of the control wafer 200. The sensing body 20 has a plurality of hollow portions 24 arranged in a predetermined regularity to define a current path portion 25 for increasing the resistance R between the first electrode 21 and the second electrode 22 on the sensing body 20. This current path portion 25 is used for current travel. Preferably, the hollow portion 24 penetrates in the thickness direction of the induction body 20. Since the thickness of the induction body 20 is relatively small, the hollow portion 24 penetrates the induction body 20 to facilitate fabrication and production.

通過在感應本體20上設置鏤空部24,可使得整個感應本體20的電流通路部25的路徑更細或者更長,相當於R=P*L/h公式中的L增加或h減少,使得第一電極21和第二電極22之間的電阻R變大,從而得到檢測精度滿足要求的電阻的大小,進而提高了感應的線性度。其中,鏤空的圖案或線條的大小和疏密程度都會影響電阻R的大小。為了不影響自電容,鏤空的圖案或線條盡可能細,因為需要手指與感應本體接觸的相對面積變大來增大自電容,如果鏤空的圖案或線條太粗的話,會減小手指與 感應本體的相對面積,從而影響手指觸摸的自電容變化量。 By providing the hollow portion 24 on the inductive body 20, the path of the current path portion 25 of the entire inductive body 20 can be made thinner or longer, which corresponds to an increase in L or a decrease in h in the formula of R=P*L/h, so that The resistance R between the one electrode 21 and the second electrode 22 becomes large, so that the magnitude of the resistance whose detection accuracy satisfies the requirements is obtained, thereby improving the linearity of the induction. Among them, the size and density of the hollow pattern or line will affect the size of the resistor R. In order not to affect the self-capacitance, the hollow pattern or the line is as thin as possible, because the relative area of the finger to contact the sensing body is increased to increase the self-capacitance, and if the hollow pattern or the line is too thick, the finger and the finger are reduced. The relative area of the body is sensed, thereby affecting the amount of self-capacitance change of the finger touch.

需要理解的是,在本發明的描述中,多個鏤空部24以預定規則排列應做廣義理解,即,多個鏤空部24在感應本體20上排列成預定形狀的陣列。例如,可選地,多個鏤空部24可沿感應本體20的長度彼此間隔開地設置成線性陣列;可選地,多個鏤空部24包括交替地設在感應本體的長度方向上的兩種形狀的鏤空部。具體地,感應本體20和鏤空部24將在下面的多個實施例中詳細描述。 It is to be understood that in the description of the present invention, the arrangement of the plurality of hollow portions 24 in a predetermined regular manner should be understood in a broad sense, that is, the plurality of hollow portions 24 are arranged on the sensing body 20 in an array of a predetermined shape. For example, optionally, the plurality of hollow portions 24 may be arranged in a linear array spaced apart from each other along the length of the sensing body 20; alternatively, the plurality of hollow portions 24 include two types alternately disposed in the longitudinal direction of the sensing body. The hollowed out part of the shape. In particular, the sensing body 20 and the hollow portion 24 will be described in detail in the various embodiments below.

In this embodiment, due to the pattern rule of the rectangular structure, the linearity is good when the finger is moved laterally or longitudinally. In addition, the spacing between the two rectangular structures can be the same, which is convenient for calculation, thereby increasing the calculation speed.

在本發明的一個實施例中,優選地,鏤空部24均勻地間隔開排列,例如,當感應本體20為矩形時,鏤空部24沿感應本體20的長度方向均勻間隔開排列,也可以稱為:鏤空部24沿電流通路部25在感應本體20上 延伸的方向均勻間隔開,由此可以增加線性度,便於計算,且計算速度和精度提高。 In an embodiment of the present invention, preferably, the hollow portions 24 are evenly spaced apart. For example, when the sensing body 20 is rectangular, the hollow portions 24 are evenly spaced along the length direction of the sensing body 20, which may also be referred to as : the hollow portion 24 is on the sensing body 20 along the current path portion 25 The directions of extension are evenly spaced, thereby increasing linearity, facilitating calculations, and increasing computational speed and accuracy.

在本發明的另一個實施例中,感應本體20包括第一本體部201和第二本體部202,第一本體部201和第二本體部202可以均為矩形且稱預定夾角,例如第一本體部201和第二本體部202可以彼此正交以形成為大體L形(下面簡稱為L形感應本體),第一本體部201的第二端與第二本體部202的第一端相連,第一電極21與第一本體部201的第一端相連且第二電極22與第二本體部202的第二端相連。如上所述,第一本體部201和第二本體部202可以彼此正交。由此,使得感應單元設計更加規則,從而提高對觸摸檢測元件的覆蓋率,且也可以提高檢測的線性度。可選地,第一本體部201和第二本體部202的尺寸相同,從而能夠提高運算速度。 In another embodiment of the present invention, the sensing body 20 includes a first body portion 201 and a second body portion 202. The first body portion 201 and the second body portion 202 may each be rectangular and are referred to as a predetermined angle, such as the first body. The portion 201 and the second body portion 202 may be orthogonal to each other to be formed into a substantially L shape (hereinafter simply referred to as an L-shaped sensing body), and the second end of the first body portion 201 is connected to the first end of the second body portion 202, An electrode 21 is connected to the first end of the first body portion 201 and the second electrode 22 is connected to the second end of the second body portion 202. As described above, the first body portion 201 and the second body portion 202 may be orthogonal to each other. Thereby, the sensing unit design is made more regular, thereby improving the coverage of the touch detecting element, and also improving the linearity of the detection. Alternatively, the first body portion 201 and the second body portion 202 are the same in size, so that the operation speed can be improved.

在本發明的再一個實施例中,感應本體20包括第一至第三本體部201、202、203。第一本體部201和第二本體部202分別連接在第三本體部203的兩端並且位於第三本體部203的同一側,第一本體部201和第二本體部202分別與第三本體部203成預定角度。優選地,第一至第三本體部201、202、203可以均為矩形,第一本體部201和第二本體部202分別與第三本體部203正交(下面簡稱為大體U形感應本體)。第一電極21與第一本體部 201的第一端相連且第二電極22與第二本體部202的第二端相連。由此,使得感應單元設計更加規則,從而提高對觸摸檢測元件的覆蓋率,且可以提高檢測的線性度。可選地,第一本體部201和第二本體部202的尺寸相同,從而能夠提高運算速度。 In still another embodiment of the present invention, the sensing body 20 includes first to third body portions 201, 202, 203. The first body portion 201 and the second body portion 202 are respectively connected to the two ends of the third body portion 203 and located on the same side of the third body portion 203, and the first body portion 201 and the second body portion 202 and the third body portion respectively 203 is a predetermined angle. Preferably, the first to third body portions 201, 202, 203 may all be rectangular, and the first body portion 201 and the second body portion 202 are orthogonal to the third body portion 203, respectively (hereinafter referred to as a substantially U-shaped sensing body). . First electrode 21 and first body portion The first ends of 201 are connected and the second electrode 22 is connected to the second end of the second body portion 202. Thereby, the sensing unit design is made more regular, thereby improving the coverage of the touch detecting element, and the linearity of detection can be improved. Alternatively, the first body portion 201 and the second body portion 202 are the same in size, so that the operation speed can be improved.

下面首先參考第6-17圖描述中根據本發明實施例的具有大體矩形的感應本體20的觸摸檢測元件100進行說明。 The description will first be made with reference to the touch detecting element 100 having the substantially rectangular sensing body 20 according to an embodiment of the present invention with reference to the description of Figs. 6-17.

感應本體20具有第一端和第二端,第一電極21與感應本體20的第一端相連,第二電極22與感應本體20的第二端相連,電流通路部25以曲線方式延伸在第一和第二端之間,以使得在電流通路部25的延伸方向上電流通路部25的長度L大於感應本體20的長度,即增加電流的流動長度,從而增大感應本體20的電阻。例如感應本體20為矩形時,其長度方向即為第一端至第二端的方向,如第7-10圖所示,第一電極21連接在感應本體20的第一端(即圖中矩形的左端),第二電極22連接在感應本體20的第二端(即圖中矩形的右端),其中電流流通方向在圖中如箭頭所示。 The sensing body 20 has a first end and a second end. The first electrode 21 is connected to the first end of the sensing body 20, the second electrode 22 is connected to the second end of the sensing body 20, and the current path portion 25 extends in a curved manner. Between the first and second ends, the length L of the current path portion 25 in the extending direction of the current path portion 25 is larger than the length of the sensing body 20, that is, the flow length of the current is increased, thereby increasing the resistance of the sensing body 20. For example, when the sensing body 20 is rectangular, the length direction thereof is the direction from the first end to the second end. As shown in FIGS. 7-10, the first electrode 21 is connected to the first end of the sensing body 20 (ie, rectangular in the figure). The left end 22 is connected to the second end of the sensing body 20 (i.e., the right end of the rectangle in the figure), wherein the current flow direction is as indicated by the arrow in the figure.

根據本發明實施例的觸摸檢測元件100,通過設置感應本體20上的鏤空部24,使得電流通路部25的路徑更長,從而增加了R=P*L/h公式中的L,進而使得第一電極21和第二電極22之間的電阻R變大,由此提高了感應的線性度。 According to the touch detecting element 100 of the embodiment of the present invention, by providing the hollow portion 24 on the sensing body 20, the path of the current path portion 25 is made longer, thereby increasing L in the formula of R=P*L/h, thereby making the first The electric resistance R between the one electrode 21 and the second electrode 22 becomes large, thereby increasing the linearity of induction.

The up-and-down direction is orthogonal to the 25 of the current path portion Extend the direction. Of course, the invention is not limited thereto, and in other examples, each hollow portion 24 may also be generally I-shaped or generally H-shaped, not shown.

Projections partially spaced apart from each other in the width direction (up and down direction in FIG. 8) of the induction body 20 and on a plane orthogonal to the width direction of the induction body 20 (horizontal plane in FIG. 8) are partially overlapped.

其中,電流通路部25延伸在第一端和第二端之間且在正交於其延伸方向的平面上的截面積小於感應本體20在平面上的截面積,換言之,電流通路部25在上下方向上的寬度h小於感應本體20的寬度。例如當感應本體20為矩形時,其長度方向即為第一端至第二端的方向,如第10-14圖所示,第一電極21連接在感應本體20的第一端(即圖中矩形的左端),第二電極22連接在感 應本體20的第二端(即圖中矩形的右端),其中電流流通方向在圖中如箭頭所示。 Wherein, the current path portion 25 extends between the first end and the second end and has a cross-sectional area on a plane orthogonal to the extending direction thereof smaller than a cross-sectional area of the sensing body 20 in a plane, in other words, the current path portion 25 is up and down. The width h in the direction is smaller than the width of the sensing body 20. For example, when the sensing body 20 is rectangular, the length direction thereof is the direction from the first end to the second end. As shown in FIGS. 10-14, the first electrode 21 is connected to the first end of the sensing body 20 (ie, the rectangle in the figure).

The length L is simultaneously reduced by the width h, thereby increasing the resistance R between the first electrode 21 and the second electrode 22, thereby increasing the linearity of induction.

在本發明實施例的一個示例中,電流通路部25鄰近感應本體20的沿延伸方向延伸的一個側邊。可選地,如第11圖和第12圖所示,鏤空部24為大體T形或大體倒L形。當然本發明並不限於此,鏤空部24還可以為大體矩形、大體U形、大體H形或大體工字形等其他形狀(圖未示出)。可選地,電流通路部25鄰近感應本體20的上邊且沿左右方向延伸,電流流向如第11圖和第12圖中箭頭方向所示。當然,電流通路部25也可以鄰近感應本體20的下邊且沿左右方向延伸(圖未示出)。 In an example of an embodiment of the present invention, the current path portion 25 is adjacent to one side of the sensing body 20 that extends in the extending direction. Alternatively, as shown in Figures 11 and 12, the hollow portion 24 is generally T-shaped or generally inverted L-shaped.

具體地,第一組鏤空部24a的上端與感應本體20的上邊緣連接,且第二組鏤空部24b的下端與感應本體20的下邊緣連接,此時當控制晶片200向第一電極21及/或第二電極22施加電平信號而產生的電流方向如第13和14圖中的箭頭所示,電流沿曲線流動,使得電流通路部25在上下方向上的寬度減小,即減小了R=P*L/h公式中的h,進而使得第一電極21和第二電極22之間的電阻R變大。 Specifically, the upper end of the first group of hollow portions 24a is connected to the upper edge of the sensing body 20, and the lower end of the second group of hollow portions 24b is connected to the lower edge of the sensing body 20. At this time, when the control wafer 200 is directed to the first electrode 21 and Or the current direction generated by applying the level signal to the second electrode 22 is as indicated by the arrows in FIGS. 13 and 14, the current flows along the curve, so that the width of the current path portion 25 in the up and down direction is reduced, that is, reduced. R in the formula of R = P * L / h, which in turn causes the resistance R between the first electrode 21 and the second electrode 22 to become large.

可選地,第一組鏤空部24a中的每一個均為大體倒T形,且第二組鏤空部24b中的每一個均為大體T形,如第13圖所示,例如,大體倒T形的鏤空部24a包括大致水準的第一臂和大致豎直的第二臂,本領域內的普通技術人員可以理解,第一臂還可與水準方向偏離預定角度且第二臂可與豎直方向偏離預定角度(圖未示出)。 Optionally, each of the first set of hollow portions 24a is generally inverted T-shaped, and each of the second set of hollow portions 24b is substantially T-shaped, as shown in FIG. 13, for example, generally inverted T The shaped hollow portion 24a includes a generally first arm and a generally vertical second arm, as will be understood by those of ordinary skill in the art, the first arm can also be offset from the level by a predetermined angle and the second arm can be upright The direction deviates from a predetermined angle (not shown).

可選地,第一組鏤空部24a中的每一個均為大體L形,且第二組鏤空部24b中的每一個均為大體倒L形,如第14圖所示。例如,大體L形的鏤空部24a包括大致水準的第一臂和大致豎直的第二臂,本領域內的普通技術人員可以理解,第一臂也可與水準方向偏離預定角度且第二臂可與豎直方向偏離預定角度(圖未示出)。 Optionally, each of the first set of hollow portions 24a is generally L-shaped, and each of the second set of hollow portions 24b is generally inverted L-shaped, as shown in FIG. For example, the generally L-shaped hollow portion 24a includes a generally first arm and a generally vertical second arm, as will be understood by those of ordinary skill in the art, the first arm can also be offset from the level by a predetermined angle and the second arm It may be offset from the vertical direction by a predetermined angle (not shown).

當然,本發明並不限於此。本發明的一些示例中,彼此相對的第一組鏤空部24a和第二組鏤空部24b還可以為其他形狀,只要能滿足在上下方向上將電流通路部25的寬度減小即可,例如大體矩形、大體U形(例如封閉端為平直線的U形、或封閉端為弧形的U形),還例如為H形或工字形,其中H形或工字形鏤空部包括大致平行的第一臂和第二臂以及連接在第一臂和第二臂之間的第三臂,還可例如為其他形狀(圖未示出)。 Of course, the invention is not limited thereto. In some examples of the present invention, the first group of hollow portions 24a and the second group of hollow portions 24b opposed to each other may have other shapes as long as the width of the current path portion 25 is reduced in the up and down direction, for example, generally Rectangular, generally U-shaped (for example, a U-shaped closed end, or a U-shaped closed end), and is also, for example, H-shaped or I-shaped, wherein the H-shaped or I-shaped hollow portion includes a substantially parallel first The arm and the second arm and the third arm coupled between the first arm and the second arm may also be, for example, of other shapes (not shown).

Thereby, the total length of the current path portion 25, that is, the length of the flow path of the current is increased and the width is decreased. For example, when the sensing body 20 is rectangular, as shown in FIGS. 15-17, one of the current path portions 25 is adjacent to the upper side of the sensing body 20 and extends in the left-right direction, and the other current path portion 25 is adjacent to the lower side of the sensing body 20 and Extends in the left and right direction.

The length L is simultaneously reduced by the width h, thereby increasing the resistance R between the first electrode 21 and the second electrode 22, thereby increasing the linearity of induction.

According to the touch detecting element 100 of the embodiment of the present invention, by providing the hollow portion 24 on the L-shaped sensing body 20, the path of the current path portion 25 is made longer, thereby increasing L in the formula of R=P*L/h, and further The resistance R between the first electrode 21 and the second electrode 22 is made larger, thereby increasing the linearity of induction.

Alternately arranged and partially overlapping in a direction orthogonal to the direction of extension.

在本發明實施例的第一個示例中,每個鏤空部24均為矩形,如第18圖所示。也就是說,在這些示例中,第一組鏤空部24a和第二組鏤空部24b為分別為多個間隔開的矩形且在L形感應本體的長度方向上交替佈 置、且在與長度方向垂直的方向上部分重疊,換言之,在第一本體部201上,第一組鏤空部24a和第二組鏤空部24b在左右方向上交替佈置且在上下方向上部分重疊,在第二本體部202上,第一組鏤空部24a和第二組鏤空部24b在上下方向上交替佈置且在左右方向上部分重疊。當然,本發明並不限於此,在其他示例中,每個鏤空部24還可為大體工字形或大體H形,圖未示出。 In the first example of the embodiment of the present invention, each of the hollow portions 24 is rectangular as shown in Fig. 18. That is, in these examples, the first set of hollow portions 24a and the second set of hollow portions 24b are respectively a plurality of spaced apart rectangles and are alternately arranged in the longitudinal direction of the L-shaped sensing body. And partially overlapping in a direction perpendicular to the longitudinal direction, in other words, on the first body portion 201, the first group of hollow portions 24a and the second group of hollow portions 24b are alternately arranged in the left-right direction and partially overlapped in the up-and-down direction. On the second body portion 202, the first group of hollow portions 24a and the second group of hollow portions 24b are alternately arranged in the up and down direction and partially overlapped in the left and right direction. Of course, the invention is not limited thereto, and in other examples, each hollow portion 24 may also be generally I-shaped or generally H-shaped, not shown.

在本發明實施例的一些示例中,第一組鏤空部24a中的每一個均為大體倒T形,且第二組鏤空部24b中的每一個均為大體T形。也就是說,如第19圖中所示,第一組中的大體倒T形的鏤空部24a在L形感應本體的長度方向上彼此間隔開,第二組中的大體T形的鏤空部24b在L形感應本體的長度方向上彼此間隔開且與第一組中的鏤空部24a交替佈置且在與長度方向垂直的方向上部分重疊。換言之,在第一本體部201上,第一組鏤空部24a和第二組鏤空部24b在左右方向上交替佈置且在上下方向上部分重疊,此時,第一組鏤空部24a的上端與第一本體部201的上邊緣連接,且第二組鏤空部24b的下端與第一本體部201的下邊緣連接。在第二本體部202上,第一組鏤空部24a和第二組鏤空部24b在上下方向上交替佈置且在左右方向上部分重疊。此時,第一組鏤空部24a 的右端與第一本體部201的右邊緣連接,且第二組鏤空部24b的左端與第一本體部201的左邊緣連接。 In some examples of embodiments of the invention, each of the first set of hollow portions 24a is generally inverted T-shaped, and each of the second set of hollow portions 24b is generally T-shaped. That is, as shown in Fig. 19, the substantially inverted T-shaped hollow portions 24a in the first group are spaced apart from each other in the longitudinal direction of the L-shaped sensing body, and the substantially T-shaped hollow portions 24b in the second group They are spaced apart from each other in the longitudinal direction of the L-shaped sensing body and alternately arranged with the hollow portions 24a in the first group and partially overlap in the direction perpendicular to the longitudinal direction. In other words, on the first body portion 201, the first group of hollow portions 24a and the second group of hollow portions 24b are alternately arranged in the left-right direction and partially overlapped in the up-and-down direction. At this time, the upper end of the first group of hollow portions 24a and the first portion The upper edge of a body portion 201 is coupled, and the lower end of the second set of hollow portions 24b is coupled to the lower edge of the first body portion 201. On the second body portion 202, the first group of hollow portions 24a and the second group of hollow portions 24b are alternately arranged in the up and down direction and partially overlapped in the left and right direction. At this time, the first set of hollow portions 24a The right end of the second body portion 201 is connected to the right edge of the first body portion 201, and the left end of the second body portion 24b is connected to the left edge of the first body portion 201.

由此,當控制晶片200向第一電極21及/或第二電極22施加電平信號而產生的電流沿曲線流動,使得電流通路部25的路徑更長,從而增加了R=P*L/h公式中的L,進而使得第一電極21和第二電極22之間的電阻R變大。 Thereby, the current generated when the control wafer 200 applies the level signal to the first electrode 21 and/or the second electrode 22 flows along the curve, so that the path of the current path portion 25 is longer, thereby increasing R = P * L / L in the formula h further increases the resistance R between the first electrode 21 and the second electrode 22.

在本發明實施例的另一些示例中,第一組鏤空部24a中的每一個均為大體L形,且第二組鏤空部24b中的每一個均為大體倒L形,第一組鏤空部24a和第二組鏤空部24b構成多對,每一對鏤空部24中的大體L形鏤空部24a與大體倒L形鏤空部24b彼此相對、在延伸方向上交叉設置且在正交於所述延伸方向的方向上部分重疊。也就是說,如第20圖所示,第一組中的大體L形的鏤空部24a在L形感應本體的長度方向上彼此間隔開,第二組中的大體倒L形鏤空部24b在長度方向上彼此間隔開且與第一組中的鏤空部24a交叉佈置以形成多對彼此相對的鏤空部,且每對中的鏤空部24a和24b在與長度方向垂直的方向上部分重疊。換言之,在第一本體部201上,每對中的鏤空部24a和24b在左右方向上交叉設置且在上下方向上部分重疊,此時,第一組鏤空部24a的上端與第一本體部201的上邊緣連接,且第二組鏤空部24b的下端 與第一本體部201的下邊緣連接。而在第二本體部202上,每對中的鏤空部24a和24b在上下方向上交叉設置且在左右方向上部分重疊。此時,第一組鏤空部24a的右端與第一本體部201的右邊緣連接,且第二組鏤空部24b的左端與第一本體部201的左邊緣連接。 In still other examples of embodiments of the present invention, each of the first set of hollow portions 24a is generally L-shaped, and each of the second set of hollow portions 24b is generally inverted L-shaped, the first set of hollow portions 24a and the second set of hollow portions 24b constitute a plurality of pairs, and the substantially L-shaped hollow portion 24a and the substantially inverted L-shaped hollow portion 24b of each pair of hollow portions 24 are opposed to each other, intersect in the extending direction, and are orthogonal to the The directions of the extension directions partially overlap. That is, as shown in Fig. 20, the substantially L-shaped hollow portions 24a in the first group are spaced apart from each other in the longitudinal direction of the L-shaped sensing body, and the substantially inverted L-shaped hollow portions 24b in the second group are in the length. The directions are spaced apart from each other and are arranged to cross the hollow portions 24a in the first group to form a plurality of pairs of hollow portions opposed to each other, and the hollow portions 24a and 24b in each pair partially overlap in a direction perpendicular to the longitudinal direction. In other words, on the first body portion 201, the hollow portions 24a and 24b of each pair are arranged to intersect in the left-right direction and partially overlap in the up-and-down direction. At this time, the upper end of the first group of hollow portions 24a and the first body portion 201 The upper edge is connected and the lower end of the second set of hollow portions 24b It is connected to the lower edge of the first body portion 201. On the second body portion 202, the hollow portions 24a and 24b in each pair are arranged to intersect in the up and down direction and partially overlap in the left and right direction. At this time, the right end of the first group hollow portion 24a is connected to the right edge of the first body portion 201, and the left end of the second group hollow portion 24b is connected to the left edge of the first body portion 201.

這裡,可以理解的是,術語“部分重疊”是指:在第一本體部201中,每對中的鏤空部24a和24b的第一支(第20圖中的豎直支)在左右方向上間隔開且它們在正交於左右方向的平面(第20圖中的豎直平面)上的投影部分重疊;在第二本體部202中,每對中的鏤空部24a和24b的第一支(第20圖中的豎直支)在上下方向上間隔開且它們在正交於上下方向的平面(第20圖中的水平面)上的投影部分重疊。 Here, it is to be understood that the term "partially overlapping" means that in the first body portion 201, the first branch of the hollow portions 24a and 24b in each pair (the vertical branch in Fig. 20) is in the left-right direction The projections are spaced apart and their projections on the plane orthogonal to the left-right direction (the vertical plane in Fig. 20) overlap; in the second body portion 202, the first branches of the hollow portions 24a and 24b in each pair ( The vertical branches in Fig. 20 are spaced apart in the up and down direction and their projections on the plane orthogonal to the up and down direction (the horizontal plane in Fig. 20) partially overlap.

此外,可以理解的是,術語“交叉設置”是指:在第一本體部201中,每對中的鏤空部24a和24b的第二支(第20圖中的水準支)在上下方向上間隔開且在正交於上下方向的平面(第20圖中的水平面)上的投影部分重疊;在第二本體部202中,每對中的鏤空部24a和24b的第二支(第20圖中的豎直支)在左右方向上間隔開且它們在正交於左右方向的平面(第20圖中的豎直平面)上的投影部分重疊。 Further, it is to be understood that the term "cross setting" means that in the first body portion 201, the second branch of the hollow portions 24a and 24b in each pair (the leveling branch in Fig. 20) is spaced in the up and down direction The projections on the plane orthogonal to the up and down direction (the horizontal plane in FIG. 20) partially overlap; in the second body portion 202, the second branch of the hollow portions 24a and 24b in each pair (Fig. 20) The vertical branches are spaced apart in the left-right direction and their projections on the plane orthogonal to the left-right direction (the vertical plane in Fig. 20) partially overlap.

由此,當控制晶片200向第一電極21及/或第二電極22施加電平信號而產生的電流方向如第20圖中的箭頭所示,電流沿曲線流動,使得電流通路部25的路徑更長,從而增加了R=P*L/h公式中的L,進而使得第一電極21和第二電極22之間的電阻R變大。 Thus, when the control wafer 200 applies a level signal to the first electrode 21 and/or the second electrode 22 to generate a current direction as indicated by an arrow in FIG. 20, the current flows along the curve so that the path of the current path portion 25 It is longer, thereby increasing L in the formula of R = P * L / h, thereby making the resistance R between the first electrode 21 and the second electrode 22 large.

在本發明實施例的另一些示例中,第一組中的鏤空部24a為大體倒V形,第二組中的鏤空部24b為大體V形,第一組中的每一個鏤空部24a在延伸方向上橫跨第二組中的相鄰兩個鏤空部24b的相鄰的兩個分支。也就是說,如第21圖中所示,在第一本體部201上,第一組中的大體倒V形的鏤空部24a在左右彼此間隔開,第二組中的大體V形的鏤空部24b在左右方向上彼此間隔開且與第一組中的鏤空部24a交替佈置以使得第一組中的鏤空部24a在左右方向上橫跨位於其下方的第二組中的相鄰兩個鏤空部24b的兩個分支。在第二本體部202上,第一組中的大體倒V形的鏤空部24a在上下彼此間隔開,第二組中的大體V形的鏤空部24b在上下方向上彼此間隔開且與第一組中的鏤空部24a交替佈置以使得第一組中的鏤空部24a在上下方向上橫跨位於其左側的第二組中的相鄰兩個鏤空部24b的兩個分支。 In still other examples of embodiments of the present invention, the hollow portion 24a in the first group is generally inverted V-shaped, and the hollow portion 24b in the second group is generally V-shaped, and each of the hollow portions 24a in the first group is extended The two adjacent branches of the adjacent two hollow portions 24b in the second group are traversed in the direction. That is, as shown in Fig. 21, on the first body portion 201, the substantially inverted V-shaped hollow portions 24a in the first group are spaced apart from each other on the left and right, and the substantially V-shaped hollow portions in the second group 24b are spaced apart from each other in the left-right direction and alternately arranged with the hollow portions 24a in the first group such that the hollow portions 24a in the first group straddle two adjacent hollows in the second group located below in the left-right direction Two branches of the portion 24b. On the second body portion 202, the generally inverted V-shaped hollow portions 24a of the first group are spaced apart from each other, and the substantially V-shaped hollow portions 24b of the second group are spaced apart from each other in the up and down direction and are first The hollow portions 24a in the group are alternately arranged such that the hollow portions 24a in the first group straddle the two branches of the adjacent two hollow portions 24b in the second group on the left side thereof in the up and down direction.

由此,當控制晶片200向第一電極21及/或第二電極22施加電平信號而產生的電流方向如第21圖中的 箭頭所示,電流沿曲線流動,使得電流通路部25的路徑更長,從而增加了R=P*L/h公式中的L,進而使得第一電極21和第二電極22之間的電阻R變大。 Thus, when the control wafer 200 applies a level signal to the first electrode 21 and/or the second electrode 22, the current direction is generated as in FIG. As indicated by the arrow, the current flows along the curve, so that the path of the current path portion 25 is longer, thereby increasing L in the formula of R = P * L / h, thereby making the resistance R between the first electrode 21 and the second electrode 22 Become bigger.

That is, as shown in Fig. 22, the substantially inverted F-shaped hollow portions 24a in the first group are spaced apart from each other in the longitudinal direction of the L-shaped sensing body, and the substantially F-shaped hollow portions 24b in the second group are in the L The shape sensing bodies are spaced apart from each other in the longitudinal direction and are arranged to intersect with the hollow portions 24a in the first group to form a plurality of pairs of hollow portions opposed to each other, and the hollow portions 24a and 24b in each pair are in a direction perpendicular to the longitudinal direction Partial overlap. In other words, on the first body portion 201, the hollow portions 24a and 24b of each pair are arranged to intersect in the left-right direction and partially overlap in the up-and-down direction. At this time, the upper end of the first group of hollow portions 24a and the first body portion 201 The upper edges are connected, and the lower ends of the second set of hollow portions 24b are connected to the lower edge of the first body portion 201. On the second body portion 202, the hollow portions 24a and 24b in each pair are arranged to intersect in the up and down direction and partially overlap in the left and right direction. At this time, the first set of hollow portions 24a The right end of the second body portion 201 is connected to the right edge of the first body portion 201, and the left end of the second body portion 24b is connected to the left edge of the first body portion 201.

在本實施例中,術語“部分重疊”是指:在第一本體部201中,每對中的鏤空部24a和24b的第一支(第22圖中的豎直支)在左右方向上間隔開且它們在正交於左右方向的平面(第22圖中的豎直平面)上的投影部分重疊;在第二本體部202中,每對中的鏤空部24a和24b的第一支(第22圖中的豎直支)在上下方向上間隔開且它們在正交於上下方向的平面(第22圖中的水平面)上的投影部分重疊。 In the present embodiment, the term "partially overlapping" means that in the first body portion 201, the first branch (the vertical branch in Fig. 22) of the hollow portions 24a and 24b in each pair is spaced in the left-right direction And their projections on the plane orthogonal to the left-right direction (the vertical plane in Fig. 22) partially overlap; in the second body portion 202, the first branch of the hollow portions 24a and 24b in each pair (the first The vertical branches in Fig. 22 are spaced apart in the up and down direction and their projections on the plane orthogonal to the up and down direction (the horizontal plane in Fig. 22) partially overlap.

在本實施例中,術語“交叉設置”是指:在第一本體部201中,每對中的鏤空部24a和24b的第二支(第22圖中的水準支)在上下方向上間隔開且在正交於上下方向的平面(第22圖中的水平面)上的投影部分重疊;在第二本體部202中,每對中的鏤空部24a和24b的第二支(第22圖中的豎直支)在左右方向上間隔開且它們在正交於左右方向的平面(第22圖中的豎直平面)上的投影部分重疊。換言之,對於每對中的鏤空部24a和24b,鏤空部24a的每個短支部分插入到鏤空部24b的相鄰短支之間。 In the present embodiment, the term "cross setting" means that in the first body portion 201, the second branch of the hollow portions 24a and 24b in each pair (the leveling branch in Fig. 22) is spaced apart in the up and down direction. And the projections on the plane orthogonal to the up and down direction (the horizontal plane in FIG. 22) partially overlap; in the second body portion 202, the second branch of the hollow portions 24a and 24b in each pair (the image in FIG. 22) The vertical branches are spaced apart in the left-right direction and their projections on the plane orthogonal to the left-right direction (the vertical plane in Fig. 22) partially overlap. In other words, for the hollow portions 24a and 24b in each pair, each short branch portion of the hollow portion 24a is inserted between adjacent short branches of the hollow portion 24b.

由此,當控制晶片200向第一電極21及/或第二電極22施加電平信號而產生的電流方向如第22圖中的箭頭所示,電流沿曲線流動,使得電流通路部25的路徑更長,從而增加了R=P*L/h公式中的L,進而使得第一電極21和第二電極22之間的電阻R變大。 Thus, when the control wafer 200 applies a level signal to the first electrode 21 and/or the second electrode 22, the current direction is generated as shown in FIG. As indicated by the arrow, the current flows along the curve, so that the path of the current path portion 25 is longer, thereby increasing L in the formula of R = P * L / h, thereby making the resistance R between the first electrode 21 and the second electrode 22 Become bigger.

實施例五, Embodiment 5,

在本實施例中,感應本體20具有第一端和第二端,第一電極21與感應本體20的第一端相連,第二電極22與感應本體20的第二端相連,電流通路部25以曲線方式延伸在第一和第二端之間以便在電流通路部25的延伸方向上電流通路部25的長度L大於感應本體20的長度。其中,電流通路部25延伸在第一端和第二端之間且在正交於其延伸方向的平面上的截面積小於感應本體20在平面上的截面積,換言之,在第一本體部201上,電流通路部25在上下方向上的寬度h小於感應本體20的寬度。而在第二本體部202上,電流通路部25在左右方向上的寬度h小於感應本體20的寬度 In this embodiment, the sensing body 20 has a first end and a second end, the first electrode 21 is connected to the first end of the sensing body 20, and the second electrode 22 is connected to the second end of the sensing body 20, and the current path portion 25 The length L of the current path portion 25 is extended in a curved manner between the first and second ends so as to be longer than the length of the sensing body 20 in the extending direction of the current path portion 25. Wherein, the cross-sectional area of the current path portion 25 extending between the first end and the second end and in a plane orthogonal to the extending direction thereof is smaller than the cross-sectional area of the sensing body 20 on the plane, in other words, in the first body portion 201 The width h of the current path portion 25 in the vertical direction is smaller than the width of the inductor body 20. On the second body portion 202, the width h of the current path portion 25 in the left-right direction is smaller than the width of the sensing body 20.

根據本發明實施例的觸摸檢測元件100,通過在感應本體20上設置鏤空部24,使得電流通路部25的路徑更長且寬度減小,也就是在R=P*L/h公式中增加了長度L同時減小了寬度h,從而增加了第一電極21和第二電極22之間的電阻R,由此提高了感應的線性度。 According to the touch detecting element 100 of the embodiment of the present invention, by providing the hollow portion 24 on the sensing body 20, the path of the current path portion 25 is made longer and the width is reduced, that is, the equation of R=P*L/h is added. The length L is simultaneously reduced by the width h, thereby increasing the resistance R between the first electrode 21 and the second electrode 22, thereby increasing the linearity of induction.

在本發明實施例的一個示例中,電流通路部25鄰近感應本體20的沿延伸方向延伸的一個側邊。可選 地,如第23圖和第24圖所示,鏤空部24為大體T形或倒L形。當然本發明並不限於此,鏤空部24還可以為矩形、大體U形、H形或工字形等其他形狀(圖未示出)。可選地,在第一本體部201上,電流通路部25鄰近感應本體20的上邊且沿左右方向延伸,在第二本體部202上,電流通路部25鄰近感應本體20的右邊且沿上下方向延伸,電流流向如第23圖和第24圖中箭頭方向所示。當然,本發明並不限於此,在另一個示例中,在第一本體部201上,電流通路部25也可以鄰近感應本體20的下邊且沿左右方向延伸,在第二本體部202上,電流通路部25鄰近感應本體20的左邊且沿上下方向延伸,圖未示出。 In an example of an embodiment of the present invention, the current path portion 25 is adjacent to one side of the sensing body 20 that extends in the extending direction.

Of course, the present invention is not limited thereto, and the hollow portion 24 may also have other shapes such as a rectangle, a substantially U shape, an H shape, or an I-shape (not shown). Optionally, on the first body portion 201, the current path portion 25 is adjacent to the upper side of the sensing body 20 and extends in the left-right direction. On the second body portion 202, the current path portion 25 is adjacent to the right side of the sensing body 20 and is in the up and down direction. The current flow is shown as the direction of the arrows in Figs. 23 and 24. Of course, the present invention is not limited thereto. In another example, on the first body portion 201, the current path portion 25 may also be adjacent to the lower side of the sensing body 20 and extend in the left-right direction. On the second body portion 202, the current The passage portion 25 is adjacent to the left side of the sensing body 20 and extends in the up and down direction, not shown.

在本發明實施例的另一個示例中,電流通路部25鄰近感應本體20的沿延伸方向延伸的中心線。其中,多個鏤空部24分為沿延伸方向線性排列的第一組和第二組,第一組鏤空部24a與第二組鏤空部24b構成多對,每一對中的第一組中的鏤空部24a與第二組中的鏤空部24b在正交於延伸方向的方向上彼此相對,電流通路部25限定在第一鏤空部24a和第二組鏤空部24b之間。 In another example of an embodiment of the present invention, the current path portion 25 is adjacent to a center line of the sensing body 20 that extends in the extending direction. Wherein, the plurality of hollow portions 24 are divided into a first group and a second group linearly arranged in the extending direction, and the first group of hollow portions 24a and the second group of hollow portions 24b constitute a plurality of pairs, in the first group of each pair The hollow portion 24a and the hollow portion 24b in the second group face each other in a direction orthogonal to the extending direction, and the current path portion 25 is defined between the first hollow portion 24a and the second group hollow portion 24b.

具體地,在第一本體部201上,第一組鏤空部24a的上端與感應本體20的上邊緣連接,且第二組鏤空部24b的下端與感應本體20的下邊緣連接,在第二本體部202上,第一組鏤空部24a的右端與第二本體部202 的右邊緣連接,且第二組鏤空部24b的左端與第二本體部202的左邊緣連接,此時當控制晶片200向第一電極21及/或第二電極22施加電平信號而產生的電流方向如第25和26圖中的箭頭所示,電流沿曲線流動,使得電流通路部25在上下方向上的寬度減小,即減小了R=P*L/h公式中的h,進而使得第一電極21和第二電極22之間的電阻R變大。 Specifically, on the first body portion 201, the upper end of the first group of hollow portions 24a is connected to the upper edge of the sensing body 20, and the lower end of the second group of hollow portions 24b is connected to the lower edge of the sensing body 20, in the second body. On the portion 202, the right end of the first set of hollow portions 24a and the second body portion 202 The right edge is connected, and the left end of the second set of hollow portions 24b is connected to the left edge of the second body portion 202. At this time, when the control chip 200 applies a level signal to the first electrode 21 and/or the second electrode 22, The current direction flows as shown by the arrows in FIGS. 25 and 26, and the current flows along the curve, so that the width of the current path portion 25 in the up and down direction is reduced, that is, the h in the formula of R=P*L/h is reduced, and further The resistance R between the first electrode 21 and the second electrode 22 is made large.

可選地,第一組鏤空部24a中的每一個均為大體倒T形,且第二組鏤空部24b中的每一個均為大體T形,如第25圖所示。可選地,第一組鏤空部24a中的每一個均為大體L形,且第二組鏤空部24b中的每一個均為大體倒L形,如第26圖所示。當然,本發明並不限於此。本發明的一些示例中,彼此相對的第一組鏤空部24a和第二組鏤空部24b還可以為其他形狀,例如矩形、大體U形、H形或工字形等其他形狀(圖未示出),只要能滿足在上下方向上將電流通路部25的寬度減小即可。 Optionally, each of the first set of hollow portions 24a is generally inverted T-shaped, and each of the second set of hollow portions 24b is generally T-shaped, as shown in FIG. Optionally, each of the first set of hollow portions 24a is generally L-shaped, and each of the second set of hollow portions 24b is generally inverted L-shaped, as shown in FIG.

It suffices that the width of the current path portion 25 can be reduced in the vertical direction.

實施例六, Embodiment 6,

在本實施例中,電流通路部25為兩個,其中一個電流通路部25鄰近感應本體20的沿延伸方向延伸的一個側邊,另一個電流通路部25鄰近感應本體20的沿延伸方向延伸的另一個側邊。第27-29圖所示,在第一本體部201上,其中一個電流通路部25鄰近第一本體部201 的上邊且沿左右方向延伸,而另一個電流通路部25鄰近第一本體部201的左邊且沿左右方向延伸。在第二本體部202上,一個電流通路部25鄰近第二本體部202的右邊且沿上下方向延伸,而另一個電流通路部25鄰近第二本體部202的左邊且沿上下方向延伸。 In the present embodiment, the current path portion 25 is two, one of the current path portions 25 is adjacent to one side of the sensing body 20 extending in the extending direction, and the other current path portion 25 is adjacent to the extending direction of the sensing body 20 The other side. As shown in FIGS. 27-29, on the first body portion 201, one of the current path portions 25 is adjacent to the first body portion 201. The upper side extends in the left-right direction, and the other current path portion 25 is adjacent to the left side of the first body portion 201 and extends in the left-right direction. On the second body portion 202, one current path portion 25 is adjacent to the right side of the second body portion 202 and extends in the up and down direction, and the other current path portion 25 is adjacent to the left side of the second body portion 202 and extends in the up and down direction.

可選地,多個鏤空部24沿延伸方向線性排列,每個鏤空部24為大體X形,如第15圖所示。當然,本發明並不限於此。本發明的一些示例中,沿延伸方向線性排列的多個鏤空部24還可以為其他形狀,例如矩形、大體U形(圖未示出)、H形(如第28圖所示)或工字形(如第29圖所示)等其他形狀,還例如可以為以上各個形狀的組合,只要能滿足在感應本體20上形成兩個電流通路部即可。 Alternatively, the plurality of hollow portions 24 are linearly arranged in the extending direction, and each of the hollow portions 24 is substantially X-shaped as shown in FIG. Of course, the invention is not limited thereto. In some examples of the invention, the plurality of hollowed portions 24 linearly aligned along the direction of extension may also be other shapes, such as rectangular, generally U-shaped (not shown), H-shaped (as shown in Figure 28), or I-shaped. Other shapes, such as shown in FIG. 29, may be, for example, a combination of the above various shapes as long as the two current path portions are formed on the inductive body 20.

根據本發明實施例的觸摸檢測元件100,通過設置L形感應本體20上的鏤空部24,使得電流通路部25的路徑更長且寬度減小,也就是在R=P*L/h公式中增加了長度L同時減小了寬度h,從而增加了第一電極21和第二電極22之間的電阻R,由此提高了感應的線性度。 According to the touch detecting element 100 of the embodiment of the present invention, by providing the hollow portion 24 on the L-shaped sensing body 20, the path of the current path portion 25 is made longer and the width is reduced, that is, in the formula of R = P * L / h The length L is increased while the width h is decreased, thereby increasing the resistance R between the first electrode 21 and the second electrode 22, thereby increasing the linearity of induction.

本發明實施例中的觸摸檢測元件100中採用L形感應本體20,可以有效地減少雜訊,提高感應的線性度。不僅結構簡單,便於製作且降低了生產成本。 The L-shaped sensing body 20 is used in the touch detecting component 100 in the embodiment of the present invention, which can effectively reduce noise and improve linearity of sensing. Not only is the structure simple, it is easy to manufacture and the production cost is reduced.

上面參考第6-29圖對具有矩形和L形感應本體20的觸摸檢測元件100為例進行了說明,然而,本領域的普通技術人員在閱讀了上述技術方案之後、顯然可以理解將該方案應用到其他形狀例如大體U形的感應本體20的技術方案中,因此在此對具有大體U形感應本體20的觸摸檢測元件100不再詳細描述。 The touch sensing element 100 having the rectangular and L-shaped sensing body 20 has been described above with reference to FIGS. 6-29. However, after reading the above technical solutions, those skilled in the art can clearly understand the application of the solution. In the case of other shapes, such as a generally U-shaped sensing body 20, the touch sensing element 100 having the generally U-shaped sensing body 20 is therefore not described in detail herein.

需要說明的是,參考第30-41圖,大體U形的感應本體20包括第一至第三本體部201、202、203。第一至第三本體部201、202、203可以均為矩形。為了顯示清楚,以大體U形感應本體20的第一本體部201、第二本體部202豎直延伸且第三本體部203水準延伸而為例進行說明,也就是說,第一本體部201、第二本體部202的延伸方向為第30-41圖中的上下方向,而與延伸方向正交的方向為圖中的左右方向。第三本體部203的延伸方向為第30-41圖中的左右方向,而與延伸方向正交的方向為圖中的上下方向。 It should be noted that, referring to FIGS. 30-41, the substantially U-shaped sensing body 20 includes first to third body portions 201, 202, and 203. The first to third body portions 201, 202, 203 may all be rectangular. For the sake of clarity, the first body portion 201 and the second body portion 202 of the substantially U-shaped sensing body 20 extend vertically and the third body portion 203 is horizontally extended, that is, the first body portion 201, The extending direction of the second body portion 202 is the up-and-down direction in the 30th to 41st directions, and the direction orthogonal to the extending direction is the left-right direction in the drawing. The extending direction of the third body portion 203 is the left-right direction in the 30th to 41st directions, and the direction orthogonal to the extending direction is the up-and-down direction in the drawing.

其中第30-34圖中示出的是電流通路部25以曲線方式延伸在大體U形的感應本體20的第一和第二端之間以便在電流通路部25的延伸方向上電流通路部25的長度L大於感應本體20的長度。由此增加了R=P*L/h公式中的L,進而使得第一電極21和第二電極22之間的電阻R變大,由此提高了感應的線性度。 Wherein the third embodiment shows that the current path portion 25 extends in a curved manner between the first and second ends of the substantially U-shaped sensing body 20 so that the current path portion 25 extends in the direction in which the current path portion 25 extends. The length L is greater than the length of the sensing body 20. Thereby, L in the formula of R = P * L / h is increased, thereby making the resistance R between the first electrode 21 and the second electrode 22 large, thereby improving the linearity of induction.

第35-38圖示出的是電流通路部25以曲線方式延伸在第一和第二端之間以便在電流通路部25的延伸方向上電流通路部25的長度L大於感應本體20的長度,且電流通路部25延伸在第一端和第二端之間且在正交於其延伸方向的平面上的截面積小於感應本體20在平面上的截面積,使得電流通路部25的路徑更長且寬度減小。由此在R=P*L/h公式中增加了L且減小了h,進而使得第一電極21和第二電極22之間的電阻R變大,由此提高了感應的線性度。 35-38 illustrate that the current path portion 25 extends in a curved manner between the first and second ends such that the length L of the current path portion 25 is greater than the length of the sensing body 20 in the direction in which the current path portion 25 extends. And the cross-sectional area of the current path portion 25 extending between the first end and the second end and in a plane orthogonal to the extending direction thereof is smaller than the cross-sectional area of the sensing body 20 on the plane, so that the path of the current path portion 25 is longer. And the width is reduced. Thereby, L is added in the formula of R=P*L/h and h is decreased, thereby making the resistance R between the first electrode 21 and the second electrode 22 large, thereby improving the linearity of induction.

第39-41圖示出的是電流通路部25為兩個,其中一個電流通路部25鄰近感應本體20的沿延伸方向延伸的一個側邊,另一個電流通路部25鄰近感應本體20的沿延伸方向延伸的另一個側邊。由此使得電流通路部25的路徑更長且寬度減小,也就是在R=P*L/h公式中增加了長度L同時減小了寬度h,從而增加了第一電極21和第二電極22之間的電阻R,由此提高了感應的線性度。 FIGS. 39-41 show two current path portions 25, one of which is adjacent to one side of the sensing body 20 extending in the extending direction, and the other current path portion 25 is adjacent to the edge of the sensing body 20. The other side of the direction extends. Thereby, the path of the current path portion 25 is made longer and the width is reduced, that is, the length L is increased in the formula of R=P*L/h while the width h is decreased, thereby increasing the first electrode 21 and the second electrode. The resistance R between 22, thereby increasing the linearity of the induction.

本發明實施例中的觸摸檢測元件100中採用大體U形感應本體20,不僅結構簡單,便於製作,所有引線都在同一邊,設計方便,減少銀漿成本且可減少生產成本。 The touch sensing element 100 in the embodiment of the present invention adopts a substantially U-shaped sensing body 20, which is not only simple in structure, but also easy to manufacture, all the leads are on the same side, the design is convenient, the cost of the silver paste is reduced, and the production cost can be reduced.

在本發明的一些實施例中,觸摸檢測元件100內可包括多個L形感應單元或大體U形感應單元2,即包括多個L形感應本體或大體U形感應本體20,如第42和 43圖所示,每個感應本體20的長度不同,多個感應本體20之間依次嵌套。在本發明的實施例中,所謂依次嵌套是指外圍繞的感應本體相應地包圍內側的感應本體,這樣能夠在保證精度的同時達到較大的覆蓋率,並且降低運算的複雜度,提高觸摸檢測元件的回應速度。當然本領域技術人員還可根據第42和43圖的思想採用其他依次嵌套的方式排列感應本體。 In some embodiments of the present invention, the touch detecting component 100 may include a plurality of L-shaped sensing units or a substantially U-shaped sensing unit 2, that is, including a plurality of L-shaped sensing bodies or a generally U-shaped sensing body 20, such as 42nd and As shown in Fig. 43, each of the sensing bodies 20 has a different length, and the plurality of sensing bodies 20 are sequentially nested. In the embodiment of the present invention, the sequential nesting refers to the surrounding surrounding sensing body correspondingly surrounding the inner sensing body, which can achieve a large coverage while ensuring accuracy, and reduce the complexity of the operation and improve the touch. Detect the response speed of the component. Of course, those skilled in the art can also arrange the sensing bodies in other sequential nesting manners according to the ideas of FIGS. 42 and 43.

可選地,相鄰兩個感應單元2之間的間距相等,這樣就可以通過多個感應單元2對觸摸檢測元件的兩邊的均勻劃分,從而提高運算速度,提高計算速度,如第42圖所示。 Optionally, the spacing between two adjacent sensing units 2 is equal, so that the two sides of the touch detecting component can be evenly divided by the plurality of sensing units 2, thereby improving the calculation speed and increasing the calculation speed, as shown in FIG. 42. Show.

當然在本發明的另一個實施例中,相鄰兩個感應單元2之間的間距也可以不等,如第43圖所示,例如由於用戶往往觸摸在觸摸檢測元件100的中心部位,因此可以將觸摸檢測元件100中心部位的感應單元2之間的間距減小,從而提高中心部位的檢測精度。 Of course, in another embodiment of the present invention, the spacing between two adjacent sensing units 2 may also be unequal, as shown in FIG. 43, for example, because the user often touches the center of the touch detecting component 100, The pitch between the sensing units 2 at the center of the touch detecting element 100 is reduced, thereby improving the detection accuracy of the center portion.

需要說明的是,上述L形感應本體或大體U形感應門體20為本發明較優的實施例,其能夠獲得較大的覆蓋率,但是本發明的其他實施例可對第42和43圖進行一些等同的變化,例如大體U形感應本體20中的第一本體部201和第二本體部202可以是不平行的。 It should be noted that the above-mentioned L-shaped sensing body or the generally U-shaped sensing door body 20 is a preferred embodiment of the present invention, which can obtain a large coverage, but other embodiments of the present invention can be applied to the 42nd and 43rd drawings. Some equivalent changes are made, for example, the first body portion 201 and the second body portion 202 in the generally U-shaped sensing body 20 may be non-parallel.

本發明實施例的觸摸檢測元件100中的感應單元2採用雙端檢測,即感應單元2的兩端均具有電極,且每個電極均與控制晶片200的對應管腳相連,在進行觸摸檢測時通過感應單元2自身即可實現對觸摸點的定位。 The sensing unit 2 in the touch detecting component 100 of the embodiment of the present invention adopts double-end detection, that is, both ends of the sensing unit 2 have electrodes, and each electrode is connected to a corresponding pin of the control chip 200, when performing touch detection. The positioning of the touch point can be achieved by the sensing unit 2 itself.

有利地,本發明的實施例通過計算第一電阻R1和第二電阻R2之間比例實現觸摸位置的確定,因此相對於目前的菱形或三角形設計來說,由於在確定觸摸位置時,無需計算自電容的大小,且自電容的大小不會影響觸摸位置的精度,對自電容檢測精度的依賴降低,從而提高了測量精度,改善了線性度。此外,由於本發明實施例的第一至第三本體部中任意一個均可為形狀規則的矩形,因此相對於目前的菱形或三角形等不規則的形狀來說,也可以進一步地提高線性度。 Advantageously, embodiments of the present invention achieve a determination of the touch location by calculating the ratio between the first resistor R1 and the second resistor R2, thus, as opposed to current rhombic or triangular designs, since there is no need to calculate from the determination of the touch location The size of the capacitor, and the size of the self-capacitance does not affect the accuracy of the touch position, and the dependence on the accuracy of the self-capacitance detection is reduced, thereby improving the measurement accuracy and improving the linearity. Further, since any one of the first to third body portions of the embodiment of the present invention may have a rectangular shape, the linearity may be further improved with respect to an irregular shape such as a current rhombus or a triangle.

本領域技術人員可以理解,對於感應單元2來說,只要感應本體20的長度滿足觸摸檢測元件要求,且兩端電極分別與控制晶片200的不同的管腳相連以能夠對感應單元進行充電和放電即可,因此可以看出本發明並不限制感應單元的具體結構。感應單元可以有多種結構,本領域技術人員可在本發明上述思想的基礎上對感應單元進行變化或者改進,但是只要未脫離本發明的上述思想這些結構就應包含在本發明的範圍之內。 It can be understood by those skilled in the art that, for the sensing unit 2, as long as the length of the sensing body 20 satisfies the requirements of the touch detecting component, and the electrodes at both ends are respectively connected to different pins of the control wafer 200 to be able to charge and discharge the sensing unit. That is, it can be seen that the present invention does not limit the specific structure of the sensing unit. The sensing unit can have a variety of configurations, and those skilled in the art can make variations or improvements to the sensing unit based on the above-described ideas of the present invention, but such structures are included in the scope of the present invention without departing from the above-described ideas of the present invention.

第44圖為本發明實施例的觸摸檢測元件100中大體U形感應單元被觸摸時的示意圖。從第44圖可知,第一電極為21,第二電極為22,觸摸位置A接近於第二電極22,假設感應單元2的長度為10個單位長度,且將感應單元2均勻地分為10份,其中,感應單元2的第三本體部203的長度為4個單位長度,第一本體部201和第二本體部202的長度為3個單位長度。經過檢測,獲知第一電阻和第二電阻之比為4:1,即第一電極21至觸摸位置的長度(由第一電阻R1體現)為全部感應單元長度的80%。換句話說,觸摸點位於距離第一電極21處8個單位長度的位置,獲知,觸摸點位於距離第二電極22處2個單位長度的位置。當手指移動時,觸摸位置會相應移動,因此通過觸摸位置的變換就可判斷手指相應的移動軌跡,從而判斷用戶的輸入指令。 Figure 44 is a schematic diagram of the touch detection element 100 in the touch detection element 100 when the substantially U-shaped sensing unit is touched. As can be seen from FIG. 44, the first electrode is 21, the second electrode is 22, the touch position A is close to the second electrode 22, and the length of the sensing unit 2 is 10 unit lengths, and the sensing unit 2 is evenly divided into 10 The length of the third body portion 203 of the sensing unit 2 is 4 unit lengths, and the lengths of the first body portion 201 and the second body portion 202 are 3 unit lengths. After detecting, it is known that the ratio of the first resistance to the second resistance is 4:1, that is, the length of the first electrode 21 to the touch position (reflected by the first resistor R1) is 80% of the length of all the sensing units. In other words, the touch point is located at a position of 8 unit lengths from the first electrode 21, and it is known that the touch point is located 2 units long from the second electrode 22. When the finger moves, the touch position moves accordingly, so the change of the touch position can determine the corresponding movement trajectory of the finger, thereby judging the user's input instruction.

從第44圖的以上例子可以看出,根據本發明實施例的觸摸檢測元件的計算方式非常簡單,因此能夠極大地提高觸摸檢測元件100檢測的反應速度。 As can be seen from the above example of Fig. 44, the calculation method of the touch detecting element according to the embodiment of the present invention is very simple, and thus the reaction speed detected by the touch detecting element 100 can be greatly improved.

第45圖為本發明實施例的觸摸檢測元件100中L形感應單元被觸摸時的示意圖。從第45圖可知,第一電極為21,第二電極為22,觸摸位置A接近於第二電極22,假設感應本體20的長度為10個單位長度,且將感應本體均勻地分為10份,其中,第一本體部201的長 度為5個單位長度,第二本體部202的長度為5個單位長度。經過檢測,獲知第一電阻R1和第二電阻R2之比為9:1,即第一電極21至觸摸位置的長度(由第一電阻R1體現)為全部感應單元長度的90%。換句話說,觸摸點位於距離第一電極21處9個單位長度的位置,獲知,觸摸點位於距離第二電極22處1個單位長度的位置。 45 is a schematic diagram of the touch detection element 100 in the touch detection element 100 according to the embodiment of the present invention when the L-shaped sensing unit is touched. As can be seen from FIG. 45, the first electrode is 21, the second electrode is 22, the touch position A is close to the second electrode 22, and the length of the sensing body 20 is 10 unit lengths, and the sensing body is evenly divided into 10 parts. Wherein the length of the first body portion 201 The degree is 5 unit lengths, and the length of the second body portion 202 is 5 unit lengths. After detecting, it is learned that the ratio of the first resistor R1 and the second resistor R2 is 9:1, that is, the length of the first electrode 21 to the touch position (reflected by the first resistor R1) is 90% of the length of all the sensing units. In other words, the touch point is located at a position of 9 unit length from the first electrode 21, and it is known that the touch point is located at a position of 1 unit length from the second electrode 22.

從第45圖中可以看出,根據本發明實施例的觸摸檢測元件的計算方式非常簡單,因此能夠極大地提高觸摸檢測元件檢測的反應速度。 As can be seen from Fig. 45, the calculation method of the touch detecting element according to the embodiment of the present invention is very simple, and therefore the reaction speed detected by the touch detecting element can be greatly improved.

綜上所述,根據本發明實施例的觸控裝置,通過對感應單元2兩端的電極21、22施加電平信號,如果該感應單元2被觸碰,則該感應單元2會形成自電容,因此通過施加的電平信號可對該自電容進行充電,並根據第一電阻R1和第二電阻R2之間的比例關係確定在第一方向上的觸摸位置。例如在本發明的一個實施例中,第一電阻和第二電阻之間的比例關係根據在對所述自電容充電/放電時,從所述第一電極及/或第二電極進行檢測獲得的第一檢測值和第二檢測值之間的比例關係計算得到。因此從第一電極及/或第二電極檢測該自電容充電/放電時產生的第一檢測值和第二檢測值。這樣,通過第一檢測值和第二檢測值就能夠反應觸摸點位於該感應單元的位置,從而進一步確定觸摸點在觸摸檢測元件的位置。 In summary, the touch device according to the embodiment of the present invention applies a level signal to the electrodes 21 and 22 at both ends of the sensing unit 2. If the sensing unit 2 is touched, the sensing unit 2 forms a self-capacitance. Therefore, the self-capacitance can be charged by the applied level signal, and the touch position in the first direction is determined according to the proportional relationship between the first resistor R1 and the second resistor R2. For example, in an embodiment of the present invention, the proportional relationship between the first resistance and the second resistance is obtained by detecting from the first electrode and/or the second electrode when charging/discharging the self-capacitance. The proportional relationship between the first detected value and the second detected value is calculated. Therefore, the first detection value and the second detection value generated when the self-capacitance is charged/discharged are detected from the first electrode and/or the second electrode. In this way, the position of the touch point at the sensing unit can be reflected by the first detected value and the second detected value, thereby further determining the position of the touch point at the touch detecting element.
