Description

触摸检测组件、触控装置以及一种便携式电子设备 The touch detection component, the touch device and a portable electronic device

技术领域 FIELD

[0001] 本实用新型涉及电子设备设计及制造技术领域,尤其涉及一种触摸检测组件、具有所述触摸检测组件的触控装置以及便携式电子设备。 [0001] The present invention relates to an electronic device design and manufacturing technology, and more particularly relates to a touch detection component, having a touch device and the touch detection component of the portable electronic device.

背景技术 Background technique

[0002] 目前触摸检测组件(触摸屏)在手机,PDA(个人数字助理),GPS (全球定位系统),PMP(MP3, MP4等),甚至平板电脑等电子设备中得到了应用。 [0002] Currently touch detection component (touch screen) mobile phone, PDA (personal digital assistant), GPS (Global Positioning System), PMP (MP3, MP4, etc.), and even tablet PCs and other electronic devices has been applied. 触摸屏具有触控操作简单、便捷、人性化的优点,因此触摸屏有望成为人机互动的最佳界面而在便携式设备中得到了广泛应用。 Touch screen with a simple touch operation, convenient and user-friendly advantages, so the touch screen interface is expected to become the best human-computer interaction and has been widely used in portable devices.

[0003] 电容触摸检测组件通常被分为自电容式和互电容式两类。 [0003] The capacitive touch detection assembly is generally classified into self-capacitance and the mutual capacitance types. 现有的单层自电容触摸屏是在玻璃表面有用ITO(Indium Tin Oxides,纳米铟锡金属氧化物)制成的条形的扫描电极。 Existing single-layer capacitance touch screen is useful for scanning a bar electrode made of ITO (Indium Tin Oxides, Indium Tin nano metal oxide) on the glass surface. ITO是ー种有固定电阻率的导电物质,其在基材上的一致性比较高,从电阻屏的线性度就可以证明这一点。 ITO is a conductive substance-immobilized species ー resistivity, uniformity on a substrate which is relatively high, the linearity of screen resistance can prove it. 这些电极和地以及电路等周围环境构成ー个电容的两极。 These electrodes and the surrounding environment, and a circuit like poles ー capacitance. 当用手或触摸笔触摸的时候就会并联ー个电容到电路中去,从而使该条扫描线上的总体电容量有所改变。 When a hand or a touch pen touches will go to the parallel circuit capacitance ー, so that the overall capacitance of the article scanning line change. 在扫描的时候,控制IC通过特定的扫描方式扫描各个感应元件,井根据扫描前后的电容变化来确定触摸点的位置,从而达到人机对话交流。 When scanning, the scanning control IC respective sensing elements by a specific scanning method, the well to determine the location of a touch point based on the capacitance change before and after the scan, to achieve the man-machine dialogue. 一般情况下电容触摸屏是和TFT (Thin Film Transistor,薄膜场效应晶体管)IXD —起配对工作,而且是放置在IXD的上面。 And the capacitive touch screen is TFT (Thin Film Transistor, thin film transistor) IXD in general - from the matching operation, and is placed on top of IXD.

[0004] 图I示出了一种传统自电容式触摸检测组件。 [0004] FIG I shows a conventional self-capacitance touch detection component. 该自电容式触摸检测组件主要有双层的菱形结构感应单元100'和200',其检测原理是对X轴和Y轴分别扫描,如果检测到某个交叉点的电容变化超出了预设范围,则将该行和列的交叉点作为触摸坐标。 The capacitive touch detection component from the main structure of a double diamond shaped sensing unit 100 'and 200', which is the principle of detecting X and Y axes, respectively, scanning, if it detects a change in capacitance of the intersection outside the predetermined range , then the row and column intersection as the touch coordinates. 虽然该自电容式触摸检测组件的线性度较好,但是经常有鬼点出现,难以实现多点触摸。 Although self-linearity of the capacitive touch detection component is preferably, but often ghosts point appears, it is difficult to achieve the multi-touch. 此外,由于采用双层屏,也会导致结构及成本大幅増加,并且菱形结构在电容变化量很小的情况下会出现坐标飘移,受外界干扰影响大。 In addition, the use of the double screen, can lead to substantial cost structure and to increase in, and diamond-shaped structure in a small amount of capacitance change happens coordinate drifted outside interference big impact.

[0005]图2a示出了另ー种传统自电容式触摸检测组件。 [0005] Figure 2a shows another kind of conventional self ー capacitive touch detection component. 该自电容式触摸检测组件采用三角形图形屏结构。 Since the capacitive touch detection component triangular pattern screen structure. 该自电容式触摸检测组件包括基板300'、设置在基板300'之上的多个三角形感应单元400'、和每个三角形感应单元400'相连的多个电极500'。 Since the plurality of triangular sensing units capacitive touch detection component includes a substrate 300 ', disposed in the substrate 300' on 400 ', the sensing unit 400 and each triangle' connected to the plurality of electrodes 500 '. 图2b示出了三角形自电容式触摸检测组件的检测原理。 Figure 2b shows a triangle from the detection principle of the capacitive touch detection assembly. 如图2b所示,椭圆表示手指,SI、S2表示手指与两个三角形感应单元的接触面积。 2b, a finger is elliptic, SI, S2 represents the contact area of ​​the finger with two triangular sensing unit. 假设坐标原点在左下角,则横坐标X = S2パS1+S2)*P,其中,P为分辨率。 Assumed that the coordinate origin at the lower left, the abscissa SUPER X = S2 S1 + S2) * P, wherein, P is the resolution. 当手指向右移动时,由于S2不是线性増大,所以X坐标存在ー个偏差。 When the finger is moved to the right, due to the large zo S2 it is not linear, there is a deviation ー X coordinate. 从上述原理可以看出,传统的三角形感应单元是单端检测,即只从ー个方向检测,然后通过算法算出两个方向的坐标。 As can be seen from the above principle, the sensing unit is a conventional single triangle of the detector, i.e., detects only the ー direction, then the coordinates of two directions is calculated by the algorithm. 虽然该自电容式触摸检测组件结构简单,但并没有针对屏幕的电容感应进行优化,电容变化量小,从而导致信噪比不够。 The self is simple capacitive touch detection component structure, but it has not optimized for capacitive sensing screen, a small amount of capacitance variation, resulting in insufficient signal to noise ratio. 此外,由于该感应单元为三角形,当手指横向移动时面积不是线性増大,因此线性度较差,导致了坐标计算发生偏移,线性度不够好。 Further, since the sensing means is a triangle, when the finger is not linear enlargement of the lateral movement area large, the linearity is poor, resulting in the shifted coordinate calculation, linearity good enough.

[0006] 此外,传统电容感应单元输出的电容变化量很小,达到飞法级,其电缆杂散电容的存在,对测量电路提出了更高的要求。 [0006] Further, the conventional capacitance change amount is small capacitance sensing unit outputs, to fly stage method, the presence of stray capacitance of the cable which, for a higher measuring circuit requirements. 而且,杂散电容会随温度、位置、内外电场分布等诸多因素影响而变化,干扰甚至淹没被测电容信号。 Furthermore, stray capacitance varies with many factors can affect the temperature, position, and outside the electric field distribution, the interference signal measured capacitance even submerged. 此外,对于单层电容来说,由于Vcom电平信号的影响会对感应电容形成严重的干扰,其中,Vcom电平信号是为了防止LCD屏幕液晶老化而不停翻转的电平信号。 Further, for a single layer capacitor, because the influence of the level of the signal Vcom be a serious disturbance sensing capacitor, wherein, the level of signal Vcom to prevent the LCD screen of the liquid crystal aging kept inverted level signal.

实用新型内容 SUMMARY

[0007] 本申请基于发明人对以下事实的认识:传统的单层自电容触摸屏的感应元件为双边引线的条形。 [0007] The inventors of the present application is based on recognition of the fact: the conventional single-layer capacitance touch screen from the inductive element of bilateral lead bar. 在屏幕的尺寸确定后,该条形的尺寸就基本确定了。 After determining the size of the screen, the basic dimensions of the strip is determined. 条形感应元件的宽度大约为5_,该宽度变宽会影响线性度,而该宽度窄将会増加通道感应元件。 Strip-shaped sensing element width of about 5_, affects the linearity of a larger width, and the narrow width of increase in the channel will inductive element. 条形的长基本就是触摸屏的长度。 It is substantially the length of the long strip of the touch screen. 当条形的长宽确定之后,这个条形的两端之间的电阻就确定了。 After determining the length and width of the strip, the resistance between the two ends of the strip is determined. 电阻R = P*L/h,其中,L是感应元件的长度,h为感应元件的高度,P为ITO的方阻(即,把镀在基材上面的ITO层做成ー个正方形,然后从左边到右边的电阻,是ITO基材的ー个基本參数)。 Resistor R = P * L / h, where, L is the length of the sensing element, h is the height of the sensing element, P is the sheet resistance of ITO (i.e., a substrate having the plating layer made of ITO ー squares, then resistance from left to right, is the basic parameter ー ITO substrate). 方阻P的大小和ITO层的厚度有夫。 The thickness and size of the sheet resistance of the ITO layer P is married. 而本领域内对ITO方阻只有几个有限的标准值。 The art only a few limited resistance standard value for ITO party. 由此,当用固定的ITO方阻的基材做成单层自电容触摸屏后,每条的电阻R可以计算得到。 Thus, when a single layer made of ITO with a sheet resistance of the fixed substrate since the capacitance touch screen, each of the resistance R can be calculated. 然而,由于检测手指触摸的原理是计算电阻的比值,如果电阻R太大或太小都会影响检测精度,其中參数P是基材決定的,L和h是触摸屏大小決定的,设计时不能随意更改,所以如果感应元件做成简单的条形,电阻往往不是最合适测量的值。 However, since the finger touch detection principle is the ratio of the resistance is calculated, if the resistance R is too large or small will affect the detection accuracy, wherein the substrate is determined by parameter P, L and h are determined by the size of the touch screen and can not design changes, so if the sensing element is made simple strip, not always the most appropriate resistance value measured.

[0035] 控制芯片200分别与第一电极21和第二电极22相连,控制芯片200配置为用于向第一电极21和/或第二电极22施加电平信号以产生在第一电极21和第二电极22之间通过电流通路部25流动的电流,用于通过电流向感应本体20在被触摸时产生的自电容充电,用于在检测到至少ー个感应单元2的感应本体20被触摸时,计算至少ー个感应单元2的第一电极21和自电容之间的第一电阻与至少ー个感应单元2的第二电极22和自电容之间的第二电阻之间的比例关系,且用于根据第一电阻和第二电阻之间的比例关系确定至少ー个感应单元2的感应本体20被触摸的触摸位置。 [0035] The control chip 200 with the first electrode 21 and second electrode 22 is connected to the control chip 200 is configured for the first electrode 21 and / or the second electrode 22 is applied at the level of the signal to produce a first electrode 21 and the second electrodes 22 between the current in the current path flowing through the portion 25, for charging the capacitor 20 from the current to the induction generated by the body when touched, 20 for detecting the touched sensing unit senses at least one ー body 2 when calculating ー least one sensing unit and the first resistor with at least ー induction units and the ratio between the capacitance between the first electrode 2 from the second electrode 21 from 2 between the second resistor 22 between the capacitances, and means for determining at least one sensing unit senses ー 20 of the body 2 is a touch position according to the ratio relationship between the first and second resistors.

[0036] 具体地,第一电阻和第二电阻之间的比例关系根据在对自电容充电/放电时,从第一电极和/或第二电极进行检测获得的第一检测值和第二检测值之间的比例关系计算得到,如上所述对第一电极和第二电极的充电、放电或检测可同时进行,也可分开进行。 [0036] Specifically, the ratio between the first and second resistors based on the self-capacitance of the charge / discharge, a first detection value obtained from the first and second detection electrodes and / or the second electrode calculating the ratio between the value obtained, as described above to charge the first and second electrodes, the discharge can be performed simultaneously or detection, may be conducted separately. 当触摸检测组件控制芯片200根据第一检测值和第二检测值确定对应的感应单元被触摸吋,则触摸检测组件控制芯片200根据第一检测值和第二检测值计算第一电阻和第二电阻的比例关系,从而进一歩判断在第一方向上的触摸位置,井根据对应的感应单元2的位置确定在第二方向上的触摸位置。 When the touch detection component 200 determines the corresponding control chips sensing unit is touched inch The first detection value and the second detection value, the touch detection component 200 calculates a first control chip resistor according to a first and a second detection value and the second detected value the ratio between the resistance to ho into a touch position is determined in a first direction, determining a touch position of the well in the second direction corresponding to the position of the sensing unit 2. 最后触摸检测组件控制芯片200根据第一方向上的触摸位置和第二方向上的触摸位置就可确定触摸点在触摸检测组件上的位置。 Finally, the touch detection component 200 can determine the control chip position of the touch on the touch detection component according to a touch position on the touch position on the first and second directions. 在此还需要说明的是,在本实用新型的实施例中对于对感应单元的充电和放电次序来说没有限制,例如在一个实施例中,可以以扫描的方式对所有的感应单元2依次进行充电,接着再依次地对其进行放电检测;在另ー个实施例中,可以逐个对感应单元2进行充电和放电,例如对ー个感应単元2充电之后,接着就对其进行放电检测,对该感应单元2处理完成之后,再对下ー个感应单元2进行处理。 Here also be noted that there is no limitation on the order of charging and discharging the sensing means is in the embodiment of the present invention, for example, in one embodiment embodiment, may be a scanning manner for all the sensing unit 2 sequentially charge, followed sequentially subjected to discharge detection; ー in another embodiment, the sensing unit 2 one by one can be charged and discharged, for example after radiolabeling ー induction charging unit 2, and then subjected to discharge detection of the second processing unit after the sensing is completed, then the next ー 2 induction unit for processing. 在本实用新型的一个实施例中,触摸检测组件控制芯片200向感应单元2的第一电极21和第二电极22施加电平信号以对自电容充电,触摸检测组件控制芯片200从第一电极21和/或第二电极22进行充电检测以获得第一充电检测值和第二充电检测值。 In one embodiment of the present invention embodiment, the sensing unit 200 to the first electrodes of the touch detection component 21 of the control chip 2 from the first electrode 22 and second electrode level signal is applied to the self-capacitance charging, the touch detection component 200 control chip 21 and / or the second electrode 22 to achieve charge detecting a first charge and the second charge detection value detected value.

[0037] 具体地,本实用新型实施例的触控装置采用新颖的自电容式检测方式,在感应单元被触摸时,在感应单元的触摸点处产生自电容,且触摸点可以将感应单元分为两个电阻,在进行自电容检测的同时考虑这两个电阻就可以确定触摸点在该感应単元上的位置。 [0037] Specifically, the touch device of the present invention employ a novel embodiment of the self-capacitance detection method, when the sensing unit is touched, generates a touch point from the capacitance at the sensing unit and the touch sensing unit may be divided point two resistors, since the capacitance detection is performed taking these two resistors can determine the position of the touch on the sensing element radiolabeling. 图3为本实用新型实施例的触控装置的检测原理示意图。 FIG 3 is a schematic view of the principle of an embodiment of the invention detects a touch device. 当手指300触摸感应单元时,将相当于将感应单元分割为第一和第二两个电阻R1、R2,第一电阻Rl和第ニ电阻R2的阻值之间的比例关系与触摸点的位置相关。 When a finger touch sensing unit 300, corresponds to the sensing unit is divided into first and second resistors R1, R2 between the position of the proportional relationship, the first resistor Rl and the resistor R2 the resistance of Ni and touch point related. 例如,如图3所述,当触摸点与第一电极21较近时,则第ー电阻Rl就较小,而第二电阻R2就较大;反正,当触摸点与第二电极22较近时,则第一电阻Rl就较大,而第二电阻R2就较小。 For example, as shown in FIG. 3, when the touch point is close to the first electrode 21, the first resistor Rl ー to small, and the second resistor R2 on larger; Anyway, when the touch point and the second electrode 22 nearer when, on the larger first resistor Rl, a second resistor R2 is small. 因此,通过对第一电阻Rl和第二电阻R2的检测就可以确定触摸点在感应单元2上的位置。 Thus, by detecting the first resistor Rl and the second resistor R2 can determine the position of the touch on the sensor unit 2.

[0038] 在本实用新型的实施例中,可通过多种方式检测第一电阻Rl和第二电阻R2的电阻值,例如可通过电流的检测值、自电容的检测值、自电容的电平信号的检测值和自电容的电荷变化量检测值中的ー种或多种,从而根据这些检测值获得第一电阻Rl和第二电阻R2。 [0038] In an embodiment of the present invention, the detectable resistance of the first resistor Rl and the second resistor R2 through a variety of ways, for example by detecting the value of the current, the detected value of self-capacitance, self-capacitance levelー or more values ​​of the detection signal and the self-capacitance of the charge variation amount detection values, to obtain a first resistor Rl and the second resistor R2 in accordance with these detected values. 另外,在本实用新型的实施例中,上述检测值的检测可在对自电容充电时进行(即获得第一充电检测值和第二充电检测值),也可在自电容放电时进行(即获得第一放电检测值和第二放电检测值)。 Further, in the present embodiment of the invention, the detection value of the detection can be performed (i.e., detection value to obtain a first charge and the second charge detection value) when the self-capacitance of the charging may be performed (i.e., when the self-discharge capacitor obtaining a first discharge and the second discharge detection value detected value). 此外,在充电和放电时进行的检测可以采用多种方式。 Further, at the time of detection of the charge and discharge may be employed in various ways.

[0039] 需要说明的是,充电和放电中的至少ー个是从第一电极21和第二电极22进行的,从而能够获得反应第一电阻和第二电阻之间差值的两个检测值,即第一检测值和第二检测值。 [0039] Incidentally, the charging and discharging of at least one ー is performed from the first electrode 21 and second electrode 22, thereby obtaining a difference between two detection values ​​of the first and second resistors reaction of , i.e., a first detection value and the second detection value. 也就是说,在充电或放电时需要有电流经过第一电阻Rl和第二电阻R2,从而检测到的第一检测值和第二检测值可以反应第一电阻Rl和第二电阻R2之间的差值。 That is, the need to charge or discharge current through the first resistor Rl and the second resistor R2, thereby detecting the first detection value and the second value may be a reaction between the first detection resistor Rl and the second resistor R2 difference.

[0040] 在本实用新型的实施例中,通常需要充两次电以及进行两次检测,充电包括同时从第一电极21和第二电极22充电的情況。 [0040] In the present embodiment of the invention, it is generally necessary, and the two electrical two tests, including the charge from the first electrode while the second electrode 21 and the case 22 is charged. 在一些实施例中,还可以进行两次放电。 In some embodiments, it may also be two discharges. 为了方便起见,在以下的实施例中均是进行两次充电及两次检测。 For convenience, in the following examples were carried out twice and the charging is detected twice. 需要说明的是,进行两次充电及两次检测仅是本实用新型实施例的ー种方案,算法相对比较简单。 Incidentally, the charging twice and only twice detection embodiment of the present invention ー kinds of programs, the algorithm is relatively simple. 然而本领域技术人员也可根据上述思想増加充电及检测的次数,例如可进行三次充电和检测,之后根据第一次的充电检测值和第二次的充电检测值计算第一电阻Rl,再根据第一次的充电检测值和第三次的充电检测值计算第二电阻R2。 Those skilled in the art may also be added according to the above ideas and enlargement of the number of charge detection, for example, charging and testing three times, after calculating the first resistor Rl in accordance with the detected value of the first charge and the second charge detected value, and then in accordance with calculating a second charging resistor R2 in the first detection value and the third value of the charge detection.

[0041] 具体地,根据本实用新型的实施例包括但不限于以下几种具体測量方式进行检测: [0041] In particular, according to the embodiment of the present invention include but are not detected in the following DETAILED measurement:

[0042] I、先向感应单元的第一电极21和第二电极22施加电平信号以对自电容充电(所述自电容在感应单元被触摸产生);接着从第一电极21和/或第二电极22进行充电和检测以获得第一充电检测值和第二充电检测值。 [0042] I, Xianxiang sensing unit 21 of the first electrode and the second electrode 22 is applied to the signal level of the charge from the capacitor (capacitance from the sensing unit is touched generated); then from the first electrode 21 and / or The second detection electrode 22 and is charged to obtain a first charge and the second charge detection value detected value. 在该实施例中,由于充电是从第一电极21和第二电极22进行的,因此检测可以从第一电极21进行检測,也可以从第二电极22进行检测,或者从第一电极21和第二电极22分别进行检测。 In this embodiment, since the charging is performed from the first electrode 21 and second electrode 22, the detection can be performed from the first detection electrode 21, detection may be performed from the second electrode 22, or from the first electrode 21 and The second electrode 22 are detected. 还需要说明的是,在该实施例中,从第一电极21和第二电极22的充电可同时进行,也可分别单独进行,例如对第一电极21和第二电极22同时施加相同的电平信号以对自电容进行充电,在其他实施例中,对第一电极21和第二电极22施加的电平信号也可以不同;或者,也可以先在第一电极21上施加ー个电平信号,之后再在第二电极22上施加相同的电平信号或不同的电平信号。 It is further noted that, in this embodiment, the first electrode 21 and second electrode 22 may be charged at the same time, may be performed individually, for example, the first electrode 21 and second electrode 22 while applying the same electric level of the signal from the capacitor to charge, in other embodiments, the signal level of the first electrode 21 and second electrode 22 may be applied to different; alternatively, may be first applied ー a level on the first electrode 21 signal, then re-applied to the same or a different level of the signal level of the signal on the second electrode 22. 同样地,从第ー电极21和第二电极22的检测可以同时进行,也可分别进行。 Similarly, the detection ー electrode 21 and second electrode 22 may be performed simultaneously from, may be performed separately. 在下面的实施例中,检测与充电可以同时进行,或者分别进行。 In the following embodiment, the charging may be detected simultaneously or separately.

[0043] 2、向感应单元的第一电极21或第二电极22分两次施加电平信号以对自电容进行两次充电;在毎次充电之后从第一电极21和/或第二电极22进行检测以获得第一充电检测值和第二充电检测值。 [0043] 2, 22 to 21 or the second electrode to the first sensing unit twice for two charging electrodes of the self-capacitance level signal is applied; after every charge from secondary and / or the second electrode of the first electrode 21 22 is detected to obtain a first charge and the second charge detection value detected value. 在该实施例中,由于充电是从第一电极21或第二电极22进行的,因此检测需要从第一电极21和第二电极22分别进行,其中,从第一电极21和第二电极22的检测可同时进行,也可分别进行。 In this embodiment, since the charging is performed from the first electrode 21 or second electrode 22, thus detection requires the first electrode 21 and second electrode 22 are from, where, from the first electrode 21 and second electrode 22 the detection may be performed simultaneously, it may be performed separately. 此外,可选地,还可以在第一电极21进行两次充电,并从第一电极21进行两次检测,或者,从第二电极22进行两次充电,在第二电极22进行两次检测。 Further, optionally, also the first electrode 21 may be charged twice, and twice from the first detection electrode 21, or twice the charge from the second electrode 22, the second electrode is detected twice 22 . 在从ー个电极两次充电时,分别将另一个电极接地或接高阻以改变另ー个电极的状态。 When the charging electrodes from ー twice, respectively, the other electrode connected to ground or to alter other high impedance state ー electrodes. 例如当向感应单元的第一电极21分别两次施加电平信号以对自电容进行两次充电时,其中,两次充电中的一次充电过程中将所述第二电极22接地,另一次充电过程中将所述第ニ电极22接为高阻;当向感应单元的第二电极22分别两次施加电平信号以对自电容进行两次充电时,两次充电中的一次充电过程中将所述第一电极21接地,另一次充电过程中将所述第一电极21接为高阻。 For example, when the two are applied to the signal level of the charge from the capacitor to the first electrode twice sensing unit 21, wherein two of said primary charging of the charging process in the second ground electrode 22, and another charge Ni in the process of the first electrode 22 is connected to high impedance; when the two are applied to the second electrode signal level sensing unit 22 when the self-capacitance twice charging, charging two of the primary charging process will the first electrode 21 is grounded, the charge in the process of another first electrode 21 connected to a high impedance. 这样即使是在第一电极21进行了两次充电,由于第二电极22状态的改变,也能够在第一电极21进行两次检测,以获得能够反应第一电阻Rl和第二电阻R2之间比例关系的第一检测值和第二检测值。 Thus, even if the first electrode 21 is charged twice, due to changes in state of the second electrode 22, detection can be performed twice in the first electrode 21, can be reacted to obtain a first resistor between the second resistor R2 and Rl first detection value and the second detection value proportional relationship.

[0044] 3、向感应单元的第一电极21和第二电极22施加电平信号以对自电容充电;接着控制第一电极21和/或第二电极22接地以对自电容放电;之后从第一电极21和/或第二电极22进行放电检测以获得所述第一放电检测值和第二放电检测值。 [0044] 3, the first electrode 21 and sensing unit 22 is applied to the signal level of the charge from the capacitor to the second electrode; then the control and / or the second ground electrode 22 to the first electrode 21 of the self-discharge capacitor; after the the first electrode 21 and / or second discharge detection electrodes 22 to obtain the first discharge and the second discharge detection value detected value. 在该实施例中,由于对自电容充电是从第一电极21和第二电极22进行的,因此放电或检测就可从第一电极21和/或第二电极22进行。 In this embodiment, since the first electrode 21 can be carried out and / or the second electrode 22 pairs, thus discharging or charging the capacitor from the detection is performed from the first electrode 21 and second electrode 22. 具体地,例如可同时向第一电极21和第二电极22施加电平信号以对自电容进行充电,或者也可不同时施加电平信号。 Specifically, for example, simultaneously to the first electrode 21 and second electrode 22 is applied to the level signal from the capacitor is charged to, or may not be applied to the signal level simultaneously. 在两次放电时可均将第一电极21接地,或者均将第二电极22接地。 When both the two ground-discharge the first electrode 21 or second electrode 22 are ground.

[0045] 4、向感应单元的第一电极21或第二电极22施加电平信号以对自电容充电;接着分别控制第一电极21和第二电极22接地以对自电容放电;之后分别从第一电极21和/或第二电极22进行放电检测以获得第一放电检测值和第二放电检测值。 [0045] 4, the first electrode 21 or the second sensing unit 22 is applied to electrodes to a signal level of the charge from the capacitor; then control the first ground electrode 21 and second electrode 22 to the self-discharge capacitor; after respectively from The first electrode 21 and / or the second discharge electrode 22 to obtain a first detected value and the second discharge detection discharge detection value. 在该实施例中,由于对自电容放电是从第一电极21和第二电极22进行的,因此充电或检测就可从第一电极21和/或第二电极22进行。 In this embodiment, since the first electrode 21, the charging or the second detection electrode 22 can be performed from the first electrode 21 and / or the second electrode 22 is discharged from a self-capacitance. 在该实施例中,两次充电也可均从第一电极21进行,而将第二电极22分别接地或接为高阻。 In this embodiment, two were also charged from the first electrode 21, while the second electrode 22 are grounded or connected to high impedance. 同样地,两次充电也可均从第二电极22进行,而将第一电极21分别接地或接为高阻。 Similarly, two were also charged from the second electrode 22, and the first electrode 21 are grounded or connected to high impedance.

[0046] 5、向感应单元的第一电极21或第二电极22施加电平信号以对自电容充电;接着分别控制第一电极21或第二电极22接地以对自电容放电,之后分别从第一电极21和第二电极22进行放电检测以获得第一放电检测值和第二放电检测值。 [0046] 5 to charge the capacitor to self-level signal is applied to electrode 21 or the second sensing unit 22 of the first electrode; subsequently control the first ground electrode 21 or the second electrode 22 to self-discharge the capacitor, respectively, from then The first electrode 21 and the second discharge electrode 22 to obtain a first detected value and the second discharge detection discharge detection value. 在该实施例中,由于对自电容检测是从第一电极21和第二电极22进行的,因此充电或放电可从第一电极21和/或第二电极22进行。 In this embodiment, since the self-capacitance detection is performed from the first electrode 21 and second electrode 22, the charging or discharging may be performed from the first electrode 21 and / or the second electrode 22. 在该实施例中,两次充电也可均从第一电极21进行,而将第二电极22分别接地或接为高阻。 In this embodiment, two were also charged from the first electrode 21, while the second electrode 22 are grounded or connected to high impedance. 同样地,两次充电也可均从第二电极22进行,而将第一电极21分别接地或接为高阻。 Similarly, two were also charged from the second electrode 22, and the first electrode 21 are grounded or connected to high impedance.

[0047] 或者,在上述实施例的基础之上,还可以在充电时进行一次检测以获得第一充电检测值,在放电时进行第二次检测以获得第二放电检测值,再根据第一充电检测值和第二放电检测值获得第一电阻Rl和第二电阻R2之间的比例关系。 [0047] Alternatively, in the above embodiments described above, may also be detected once during charging detection value to obtain a first charge, a second detection time of discharge to obtain a second discharge detection value, and then according to a first detection value and the second charge-discharge detection value obtained proportional relation between the first resistor Rl and the second resistor R2.

[0048] 需要说明的是,在本实用新型的实施例中,上述第一电极21和第二电极22的功能相同,且二者可以互換,因此在上述实施例中,既可以从第一电极21检测也可以从第二电极22检测,只要能满足在检测时有电流经过第一电阻Rl和第二电阻R2即可。 [0048] Incidentally, in the embodiment of the present invention, the first electrode 21 and second electrode 22 functions the same, and both are interchangeable, and therefore in the above embodiments, either from the first electrode 21 may be detected from the detection of the second electrode 22, as long as the current through the first meet resistance Rl and the second resistor R2 to the detection.

[0049] 从上述描述中可以看出,对于本实用新型实施例的上述充电及检测方式有很多种变化,但本实用新型的实施例在于根据第一电阻Rl和第二电阻R2之间的关系,例如比例关系或者其他关系来确定触摸点的位置。 [0049] As can be seen from the above description, there are many variations and detecting the charging mode embodiment of the present invention, but the embodiment of the present invention in that a relationship between the first resistor Rl and the second resistor R2 , for example, or other proportional relationship to determine the position of the touch. 进ー步地,第一电阻Rl和第二电阻R2之间的关系需要通过自电容的充电和/或放电进行检测。ー into synchronism, the relationship between the first resistor Rl and the second resistor R2 is detected by the required self-capacitance charging and / or discharging. 如果感应単元没有被触摸,则就不会与手产生自电容,因此检测到自电容的数据会很小,不满足触摸的判断条件,对于此,在本实用新型的实施例中会不断扫描,等待手指300触摸到感应单元之后才开始计算,在此不再赘述。 If the sensor element is not touched radiolabeling, the hand does not produce self-capacitance, self-capacitance thus detected data is small, the touch does not satisfy the determination condition, for this, in the present embodiment of the invention will continue scanning, wait until the finger 300 touches counted after the sensing unit are not repeated here.

[0050] 在本实用新型的实施例中,可以以扫描的方式依次向多个感应单元施加相应的电压,同时在检测时也可以以扫描的方式依次进行检測。 [0050] In an embodiment of the present invention may be applied sequentially in a scanning manner corresponding to the plurality of voltage sensing unit can also sequentially detects a scanning manner upon detection.

[0051] 另外还需要说明的是,上述检测方式仅为本实用新型实施例的一些优选方式,本领域技术人员还可根据上述思想进行扩展、修改和变型。 [0051] It also should be noted that the detection mode only some preferred embodiments of the present invention, those skilled in the art may also be extended, modifications and variations in light of the above idea.

[0052] 图4为本实用新型实施例的触控装置的触摸检测方法流程图,下面结合图3所示的原理图一同进行说明。 [0052] FIG. 4 is an embodiment of the invention method for detecting a touch of the touch device flowchart showing the principle below in connection with FIG. 3 will be described in FIG. 触摸检测方法包括以下步骤: The touch detecting method comprising the steps of:

[0053] 步骤S401,向感应单元的两端施加电平信号,即向感应单元的第一电极21和/或第二电极22施加电平信号。 [0053] step S401, the signal is applied to both ends of a level sensing unit, namely 21 and / or 22-level signal is applied to the second electrode of the first sensing electrode unit. 在该实施例中,可向第一电极21和第二电极22施加相同的电平信号,也可施加不同的电平信号。 In this embodiment, the same may be applied to the signal level of the first electrode 21 and second electrode 22 may also be applied to different signal levels. 在其他实施例中,也可仅从第一电极21或第二电极22进行充电两次,或者第一次从第一电极21充电第二次从第二电极22充电,或者第一次从第ニ电极22充电第二次从第一电极21充电。 In other embodiments, may be performed only from the first electrode 21 or second electrode 22 charged twice, the first electrode 21 or the first charge from the second charge from the second electrode 22, or from the first ni charged electrode 22 from the second charge 21 of the first electrode.

[0054] 如果此时感应单元被手指或其他物体触摸,则该感应单元将会产生自电容Cl (參照图3),通过施加的电平信号就可对自电容进行充电。 [0054] At this time, if the sensing unit is touched with a finger or other object, the sensing unit will generate a self-capacitance CI (see FIG. 3), since the capacitor can be charged for by the level of the signal applied. 在本实用新型的实施例中,通过对自电容的充电,可以提高自电容的检测精度。 In the embodiment of the present invention embodiment, the self-capacitance of the charging, the detection accuracy can be improved self-capacitance.

[0055] 需要说明的是,如果向感应单元的两端同时施加电平信号的话,则需要相应的两个电容检测模块CTS同时从第一电极21和第二电极22进行检測。 [0055] Incidentally, if a signal is applied to both ends of the level sensing unit simultaneously, then the corresponding required two capacitors CTS detection modules simultaneously detected from the first electrode 21 and second electrode 22. 而如果分别向感应单元的两端施加的话,则仅需要ー个电容检测模块CTS即可。 If both ends are respectively applied to the sensing unit, then only necessary ー capacitance detection module to CTS. 在本实用新型的一个实施例中,第一检测值和第二检测值可以为从第一电极21和/或第二电极22检测到的电容电荷变化量A Ql和AQ2。 In one embodiment of the present invention embodiment, the first detection value and the second detection value may be a first electrode of the capacitor charge variation amount A Ql AQ2 21 and detected and / or the second electrode 22. 通过AQl与A Q2,即检测到得自电容的电荷变化量,就可以算出电阻Rl与R2的比例,从而可以算出触摸点所在的横坐标的位置,及自电容Cl所在的位置。 By AQl and A Q2, i.e., detects a change in amount of charge obtained from the capacitance ratio of the resistors Rl and R2 can be calculated, so that the position of the abscissa where the touch point may be calculated, and the position where the self-capacitance Cl.

[0056] 步骤S402,从感应単元的两端对感应单元进行检測,以获得第一检测值和第二检测值。 [0056] step S402, the sensing unit detects the induced across radiolabeling element to obtain a first detected value and the second detection value. 在该实施例中,检测可在充电时进行,也可在放电时进行。 , Can be detected at the time of charging in this embodiment, it may be performed at the time of discharge. 在上述例子中,第一检测值和第二检测值分别为AQl和AQ2。 In the above example, the first detection value and the second value are detected and AQl AQ2. 以下以第一检测值和第二检测值为电荷变化量为例进行描述,但是能够反应第一电阻Rl和第二电阻R2关系的其他检测值,例如电平信号、电流等也均可采用。 The following values ​​of the first and second detection values ​​detected variation amount of charge will be described as an example, it is possible to detect the reaction of other of the first resistor Rl and the second resistor R2 relationship, e.g. level signal, current, etc. can be employed. 在本实用新型的实施例中,从第一电极21和第二电极22进行的检测可以同时进行,也可以分别进行。 In the present embodiment of the invention, from the first detection electrode 21 and the second electrode 22 may be performed simultaneously, it may be performed separately.

[0057] 在本实用新型的一个实施例中,如果检测同时进行,则需要两个电容检测模块CTS同时对第一电极21和第二电极22进行检測。 [0057] In one embodiment of the present invention embodiment, if it is detected at the same time, two capacitors are needed CTS detection module 21 while the first electrode and the second electrode 22 is detected.

[0058] 在本实用新型的另ー个实施例中,也可采用ー个电容检测模块CTS进行检测,參照步骤S401中,在通过第一电极21对自电容Cl充满之后,即该电容检测模块CTS通过第ー电极21对自电容Cl进行检测。 [0058] In the present invention ー another embodiment, the capacitors may also be employed ー CTS detection module detects, with reference to step S401, in the capacitor 21 after the self Cl filled through the first electrode, i.e., the capacitance detection module CTS is detected by the second electrode 21 ー self capacitance Cl. 接着再通过第二电极22对自电容C2 充电,接着该电容检测模块CTS再通过第二电极22对自电容Cl进行检测。 Followed by the second electrode 22 by self charging the capacitor C2, and then the capacitance detecting electrode 22 and the second module further CTS self capacitance detected by Cl.

[0059] 由于控制芯片扫描该感应单兀时米用的相位和电平信号均一致,因此对于同一个自电容Cl来说充电时的电荷就等于它们电阻的反比。 [0059] m with the phase and level of the sensing signal coincides average single chip control due Wu scanning, so for the same time of charging a charge capacitor Cl from the inverse thereof is equal to the resistance. 假设,从感应单元的第一电极21和第二电极22对感应単元检测获得的电荷变化量分别是AQl与AQ2。 Suppose, 21 and the charge variation amount from the second pair of inductive electrode 22 obtained radiolabeling unit detects a first electrode sensing element and respectively AQl AQ2. 在本实用新型的实施例中,电容检测模块CTS可为目前已知的电容检测模块CTS。 In an embodiment of the present invention, the capacitance detection module may CTS CTS is known capacitance detection module. 在本实用新型的一个实施例中,如果采用两个电容检测模块CTS的话,则由于两个电容检测模块CTS可共用多个器件,因此不会增大控制芯片的整体功耗。 In one embodiment of the present invention embodiment, if two capacitors CTS detection module, then since the two detection capacitors CTS modules may share a plurality of devices, and therefore does not increase the overall power consumption of the control chip.

[0060] 步骤S403,根据第一检测值和第二检测值判断该感应单元是否被触摸。 [0060] step S403, the detection value based on the first detected value and determining whether the second sensing unit is touched. 具体地,在本实用新型的一个实施例中,可通过判断电荷变化量AQl与AQ2是否大于阈值来确定是否被触摸。 In particular, the present invention in one embodiment, may determine whether the touch by determining whether the amount of change of charge with AQl AQ2 greater than a threshold. 当然,在本实用新型的其他实施例中,还可设置其他判断方式,例如判断电荷变化量AQl与A Q2是否小于阈值,如果小于,则判断感应单元被触摸。 Of course, in other embodiments of the present invention embodiment, the determination may also be provided other ways, for example, a charge variation amount is determined with AQl A Q2 is smaller than the threshold value, if less than the determination sensing unit is touched. 同样地,该阈值也需要根据触摸检测组件的大小和类型,感应单元的尺寸确定。 Similarly, the threshold value may be determined according to the size and type of the touch detection component, the sensing unit.

[0061] 步骤S404,如果判断该感应单元被触摸,则此时进ー步计算相应的感应单元中所述第一电极21和所述自电容间的第一电阻与所述第二电极22和所述自电容间的第二电阻之间的比例关系。 [0061] step S404, the determination if the sensing unit is touched, this time into the calculation step ー respective sensing means of said first electrode from the first resistor 21 and the capacitance between the second electrode 22, and the ratio between the capacitance of the second resistor between the self. 并根据第一电阻和所述第二电阻之间的比例关系确定触摸物体(例如手指)的触摸位置。 And determining the touch object (e.g., a finger) touched position in accordance with a proportional relationship between the first resistor and the second resistor. 在本实用新型的实施例中,第一电阻和所述第二电阻之间的比例关系根据在对自电容充电/放电时,从第一电极21和/或第二电极22进行检测获得的第一检测值和第二检测值之间的比例关系计算得到。 In the present embodiment of the invention, the ratio between the first resistor and the second resistor according to the first capacitance from charge / discharge, is detected from the first electrode 21 and / or the second electrode 22 obtained a proportional relationship between the detected value and the second detection value is calculated. 同上,Cl所在的感应单元上的坐标即为AQ2/(AQ1+AQ2) o Supra, Cl coordinates on the sensing unit is located is the AQ2 / (AQ1 + AQ2) o

[0062] 在本实用新型的实施例中,如果感应单元的感应本体为大体U形或大体L形,则通过第一电阻和第二电阻之间的比值就可确定在感应本体上的触摸位置,以下将结合具体的例子进行详述。 [0062] In the present embodiment of the invention, if the sensing unit sensing body is a substantially U-shaped or substantially L-shaped, it is possible to determine the position of the touch on the sensor body by a ratio between the first and second resistors , in conjunction with the following specific examples will be described in detail. 但在本实用新型的其他实施例中,如果感应本体为大体矩形,则步骤S404只能计算出在感应单元的感应本体上的第一方向上的触摸位置,该第一方向可以是感应本体的长度方向(例如感应单元的水平方向)。 However, in other embodiments of the present invention embodiment, if the sensor body is substantially rectangular, only the step S404 is calculated touch position in the first direction on the sensitive body sensing unit, the first direction may be induced in the body the longitudinal direction (e.g. horizontal direction sensing unit).

[0063] 如果感应本体为矩形,则还需要确定在第二方向上的触摸位置。 [0063] If the sensor body is rectangular, it is also necessary to determine the touch position in the second direction. 在本实用新型的一个实施例中,第一方向为感应本体的长度方向,第二方向为垂直于第一方向的方向,感应本体水平设置或垂直设置。 In one embodiment of the present invention, the first direction is the longitudinal direction of the sensor body, the second direction is a direction perpendicular to the first direction, the induction body arranged horizontally or vertically disposed.

[0064] 具体地,可采用质心算法计算触摸点在第二方向上的触摸位置,以下对质心算法进行简单介绍。 [0064] Specifically, the centroid algorithm employed touched touch position in the second direction, the centroid algorithm will be briefly described. [0065] 在滑条和触摸板应用中,经常需要在具体感应单元的本质间距以上确定出手指(或其他电容性物体)的位置。 [0065] In the slider and a touch panel applications it is often necessary to determine the position of the finger (or other capacitive object) in the nature of a pitch than the specific sensing unit. 手指在滑条或触摸板上的接触面积通常大于任何个感应单元。 The contact area of ​​the finger on the touch pad or slider is typically greater than any induction units. 为了采用ー个中心来计算触摸后的位置,对这个阵列进行扫描以验证所给定的传感器位置是有效的,对于一定数量的相邻感应単元信号的要求是要大于预设触摸阈值。 To employ ー central touch position is calculated, this array is scanned to verify that a given sensor location is valid for a certain number of adjacent sensing element signals radiolabeling requirement is greater than a preset touch threshold. 在找到最为強烈的信号后,此信号和那些大于触摸阈值的临近信号均用于计算中心: After finding the strongest signal, this signal and those near the touch signal is greater than the threshold value are used to calculate the center:

Figure CN202649961UD00121

[0067] 其中,Ncent为中心处感应单元的标号,n为检测到被触摸的感应单元的个数,i为被触摸感应单元的序号,其中i大于等于2。 [0067] wherein, Ncent designated sensing unit at the center, n is the number of the detected touch sensing unit, i is the number of the touch sensing unit, where i is greater than or equal to 2.

[0068] 例如,当手指触摸在第一条通道,其电容变化量为yl,第二条通道上的电容变化量为y2和第三条通道上的电容变化量为y3吋。 [0068] For example, when the finger touches the first channel, the capacitance variation is YL, the amount of change in capacitance on the second channel is a capacitance variation in the third channel is y2 and y3 inches. 其中第二通道y2电容变化量最大。 Wherein the second channel y2 maximum capacitance variation.

[0070] 本实用新型第一方面的实施例根据上述思想提出了一种触摸检测组件。 [0070] Example embodiment of the present invention, a first aspect proposes a touch detection component based on the thought. 下面參考图6-图41描述根据本实用新型实施例的触摸检测组件100。 It is described below with reference to FIG. 6 to 41 of the present invention, the touch detection component 100 in accordance with an embodiment.

[0071] 根据本实用新型实施例的触摸检测组件100包括:基板I和多个感应単元2。 [0071] According to the present invention, the touch detection component 100 of the embodiment comprises: a substrate and a plurality of I radiolabeling sensing element 2. 其中多个感应単元2设在基板I上且彼此不相交。 Wherein the plurality of radiolabeling sensing element provided on the substrate 2, and I do not cross each other. 在本实用新型的实施例中,优选地,不相交的感应单元2之间可以相互平行。 In the embodiment of the present invention, preferably, disjoint sensing unit 2 may be parallel to each other. 可选地,不相交的感应单元2之间也可以部分地平行,但至少在基板I上感应单元2彼此不相交。 Alternatively, disjoint sensing unit 2 may be partially between the parallel, but at least does not intersect with each other in the substrate 2 I sensing unit. 但是在此需要说明的是,对于多个感应単元2来说,并不限于图5所示的结构,感应単元2还可采用其他的结构,例如感应单元2的一部分或全部具有一定的弧度等,这些均可应用在本实用新型中。 However, this should be noted that, for a plurality of radiolabeling sensing element 2 is not limited to the configuration shown in FIG. 5, the sensing element 2 radiolabeling other structures may be employed, for example, 2 part or all of the sensing unit having a certain curvature, etc. these can be used in the present invention.

[0072] 可选地,基板I为大体矩形。 [0072] Alternatively, the substrate I is generally rectangular. 这里“大体矩形”应理解为基板I的相对边可以部绝对平行,例如可以成ー个小的角度,并且基板I的每个边可以不是绝对的直。 Here, "substantially rectangular" is understood to opposite sides of the substrate I can be absolutely parallel portions, for example, into ー small angle, and each side of the substrate I may not be absolutely straight. 每个感应单元2包括感应本体20以及分别与感应本体20相连的第一电极21和第二电极22。 Each sensing unit 2 comprises a main body 20 and the first sensing electrodes and the sensing body 20 is connected to the second electrodes 22 and 21. 第一电极21和第二电极22分别与控制芯片200的对应的管脚相连。 The first electrode 21 and second electrode 22 corresponding to the pins and are connected to the control chip 200. 感应本体20具有多个镂空部24,多个镂空部24以预定规则排列以在感应本体20上限定出用于增大第一电极21和第二电极22之间的电阻R的电流通路部25,该电流通路部25用于电流的行走。 Sensing body 20 has a plurality of hollow portions 24, hollow portions 24 are arranged in a plurality of predetermined rules to fix an upper limit for increasing the sensing body 20 of the first electrode 21 and the current path of the resistor R 22 between the second electrode 25 the current path portion 25 for the traveling current. 优选地,镂空部24沿感应本体20的厚度方向贯通,由于感应本体20的厚度比较小,镂空部24贯通感应本体20便于制作和生产。 Preferably, the thickness direction of the hollow portion 24 in the body 20 through the induction, the thickness of the body 20 is relatively small induction, induction hollow portion 24 penetrating the body 20 to facilitate fabrication, and manufacture.

[0073] 通过在感应本体20上设置镂空部24,可使得整个感应本体20的电流通路部25的路径更细或者更长,相当于R = P*L/h公式中的L増加或h減少,使得第一电极21和第ニ电极22之间的电阻R变大,从而得到检测精度满足要求的电阻的大小,进而提高了感应的线性度。 [0073] By providing the hollow portion 24 in the sensor body 20 may be such that the entire path of the induced current path body portion 20, 25 finer or longer, to reduce the equivalent R = P * L / h in the formula or to increase in h L , the resistance R between the first electrode 21 and the Ni electrodes 22 becomes large, to obtain the required accuracy of the size of the detection resistor, thereby improving the linearity of the sensor. 其中,镂空的图案或线条的大小和疏密程度都会影响电阻R的大小。 Wherein the hollow size or lines will affect the density and degree of the magnitude of the resistance R. 为了不影响自电容,镂空的图案或线条尽可能细,因为需要手指与感应本体接触的相对面积变大来増大自电容,如果镂空的图案或线条太粗的话,会减小手指与感应本体的相对面积,从而影响手指触摸的自电容变化量。 In order not to affect the self-capacitance, hollow or lines as fine as possible, since the relative area requires the finger and the sensing body contact increases to enlargement of large self-capacitance, if hollow or lines too thick, it reduces the finger and the sensor body, relative area, thus affecting the amount of capacitance variation from finger touch.

[0135] 需要说明的是,參考图30-图41,大体U形的感应本体20包括第一至第三本体部201、202、203。 [0135] Note that, with reference to FIG 30- FIG 41, a generally U-shaped body 20 comprises a first inductor body portion 201, to the third. 第一至第三本体部201、202、203可以均为矩形。 The first to third body portion 201, 202 may have rectangular. 为了显示清楚,以大体U形感应本体20的第一本体部201、第二本体部202竖直延伸且第三本体部203水平延伸而为例进行说明,也就是说,第一本体部201、第二本体部202的延伸方向为图30-41中的上下方向,而与延伸方向正交的方向为图中的左右方向。 For clarity, a generally U-shaped first body portion 20 of the sensor body 201, second body portion 202 and a third body vertically extending portion 203 extends horizontally as an example, i.e., the first body portion 201, the extending direction of the second body portion 202 is the vertical direction in FIGS. 30-41, and the direction perpendicular to the extending direction of the left and right direction in FIG. 第三本体部203的延伸方向为图30-41中的左右方向,而与延伸方向正交的方向为图中的上下方向。 A body portion extending in a third direction 203 is the horizontal direction in FIG. 30-41, and the direction perpendicular to the extending direction of the vertical direction in FIG.

[0136] 其中图30-34中示出的是电流通路部25以曲线方式延伸在大体U形的感应本体20的第一和第二端之间以便在电流通路部25的延伸方向上电流通路部25的长度L大于感应本体20的长度。 [0136] FIG 30-34 wherein is shown the current path 25 in a curved portion extending between a first end and a second generally U-shaped sensing body 20 so that the current path in the extending direction of the current path portion 25 a length greater than the length L of the sensing portion 25 of the body 20. 由此增加了R = P*L/h公式中的L,进而使得第一电极21和第二电极22之间的电阻R变大,由此提高了感应的线性度。 Thereby increasing the R = P * L / h formula L, and thus the resistance R between the first electrode 21 and the second electrode 22 is increased, thereby improving the linearity of the sensor.

[0137] 图35-38示出的是电流通路部25以曲线方式延伸在第一和第二端之间以便在电流通路部25的延伸方向上电流通路部25的长度L大于感应本体20的长度,且电流通路部25延伸在第一端和第二端之间且在正交于其延伸方向的平面上的截面积小于感应本体20在平面上的截面积,使得电流通路部25的路径更长且宽度减小。 [0137] FIG. 35-38 shows a current path of a curved portion 25 extending between the first and second ends so that a current path length L is larger than the detection portion 25 of the body 20 in the extending direction of the current path portion 25 length, and the current path extending portion 25 and the cross-sectional area in a plane perpendicular to its direction of extension is smaller than the detection body between the first end and the second end 20 of the cross-sectional area in the plane, so that the path of the current path portion 25 longer and reduced width. 由此在R = P*L/h公式中増加了L且减小了h,进而使得第一电极21和第二电极22之间的电阻R变大,由此提高了感应的线性度。 Thus R = P * L / h in the formula to increase in the reduced H and L, and thus the resistance R between the first electrode 21 and second electrode 22 is increased, thereby improving the linearity of the sensor.

[0138] 图39-图41示出的是电流通路部25为两个,其中一个电流通路部25邻近感应本体20的沿延伸方向延伸的一个侧边,另ー个电流通路部25邻近感应本体20的沿延伸方向延伸的另ー个侧边。 [0138] FIG 39- FIG 41 shows a current path 25 into two portions, one of which extends along a side edge portion 25 adjacent the inductor current path extending in a direction of the body 20, a current path ー other portions of the body 25 adjacent the sensor the other two sides of the extending direction ー 20 extends. 由此使得电流通路部25的路径更长且宽度减小,也就是在R = P*L/h公式中増加了长度L同时减小了宽度h,从而增加了第一电极21和第二电极22之间的电阻R,由此提高了感应的线性度。 Whereby a current path so that the path portion 25 is longer and a reduced width, that is R = P * L / h in the formula to increase in length while reducing the width L H, thereby increasing the first electrode and the second electrode 21 22 between the resistor R, thereby improving the linearity of the sensor.

[0139] 本实用新型实施例中的触摸检测组件100中采用大体U形感应本体20,不仅结构简单,便于制作,所有引线都在同一边,设计方便,減少银浆成本且可减少生产成本。 100 [0139] embodiment of the present invention detects a touch sensor assembly employs a generally U-shaped body 20, not only the simple structure, ease of fabrication, all of the terminals are on the same side, to facilitate the design, reduce cost and reduce the silver paste production cost.

[0140] 在本实用新型的一些实施例中,触摸检测组件100内可包括多个L形感应单元或大体U形感应单元2,即包括多个L形感应本体或大体U形感应门体20,如图42和图43所示,每个感应门体20的长度不同,多个感应门体20之间相互嵌套。 [0140] In the present invention some embodiments, the touch detection component 100 may include a plurality of substantially L-shaped or U-shaped sensing unit sensing unit 2, i.e. L-shaped sensing body comprises a plurality of generally U-shaped inductor or the door body 20 , FIG. 42 and FIG. 43, the length of each different door sensor body 20, a plurality of nested inductor 20 between the door body. 在本实用新型的实施例中,所谓相互嵌套是指外围绕的感应本体相应地包围内侧的感应本体,这样能够在保证精度的同时达到较大的覆盖率,并且降低运算的复杂度,提高触摸检测组件的响应速度。 In the embodiment of the present invention, the term nested refers to the outer surrounding body corresponding to the induction surrounds the inner body induction, this can reach a larger coverage ensure accuracy while reducing the computational complexity and improve the response speed of the touch detection component. 当然本领域技术人员还可根据图42和图43的思想采用其他相互嵌套的方式排列感应本体。 Of course, those skilled in the art may use other nested induction body arranged in accordance with FIGS. 42 and 43 thought of.

[0141] 可选地,相邻两个感应单元2之间的间距相等,这样就可以通过多个感应単元2对触摸检测组件的两边的均匀划分,从而提高运算速度,提高计算速度,如图42所示。 [0141] Alternatively, the equal spacing between two adjacent sensing units 2, so that a plurality of induction radiolabeling by uniform division unit 2 on both sides of the touch detection component, thereby increasing the operation speed, speed up calculations as 42 FIG.

[0142] 当然在本实用新型的另ー个实施例中,相邻两个感应单元2之间的间距也可以不等,如图43所示,例如由于用户往往触摸在触摸检测组件100的中心部位,因此可以将触摸检测组件100中心部位的感应单元2之间的间距减小,从而提高中心部位的检测精度。 [0142] Of course, the present invention ー another embodiment, the spacing between two adjacent sensing units 2 may vary, as shown in FIG. 43, for example because the user often touches the center of the touch detection component 100 parts, so the pitch can be between the central portion 2100 of the touch sensing component detecting means is reduced, thereby improving the detection accuracy of the center portion.

[0143] 需要说明的是,上述L形感应本体或大体U形感应门体20为本实用新型较优的实施例,其能够获得较大的覆盖率,但是本实用新型的其他实施例可对图42和图43进行ー些等同的变化,例如大体U形感应门体20中的第一本体部201和第二本体部202可以是不平行的。 [0143] Incidentally, the L-shaped or substantially U-shaped sensing body door sensors invention superior embodiment 20 of the present embodiment, it is possible to obtain a larger coverage, but the present invention may be other embodiments of the 42 and FIG. 43 equivalents ー some variations, for example, substantially U-shaped induction door body portion 20 of the first body 201 and second body portion 202 may be non-parallel.

[0144] 本实用新型实施例的触摸检测组件100中的感应单元2采用双端检测,即感应单元2的两端均具有电极,且每个电极均与控制芯片200的对应管脚相连,在进行触摸检测时通过感应単元2自身即可实现对触摸点的定位。 [0144] The touch detection component 100 in the embodiment of the present invention, the sensing unit 2 uses the double end detection, i.e., both ends of the sensing unit 2 has the electrodes, and each electrode is connected with a corresponding pin of the control chip 200, in radiolabeling by induction when the touch detection unit 2 itself can achieve positioning of the touch point.

[0145] 有利地,本实用新型的实施例通过计算第一电阻Rl和第二电阻R2之间比例实现触摸位置的确定,因此相对于目前的菱形或三角形设计来说,由于在确定触摸位置时,无需计算自电容的大小,且自电容的大小不会影响触摸位置的精度,对自电容检测精度的依赖降低,从而提高了測量精度,改善了线性度。 [0145] Advantageously, embodiments of the present invention is calculated by determining the ratio between the first resistor Rl and the second resistor R2 to achieve the touch position, and therefore with respect to the current design of diamond or triangular, because the touch position is determined , without calculating from the size of the capacitor, and from the magnitude of the capacitance does not affect the accuracy of touch position detection accuracy of the capacitance reducing reliance on self, thereby improving the measurement accuracy, improved linearity. 此外,由于本实用新型实施例的第一至第三本体部中任意ー个均可为形状规则的矩形,因此相对于目前的菱形或三角形等不规则的形状来说,也可以进一歩地提高线性度。 Further, since the first body portion to the third embodiment of the present invention in embodiments may be any number of ー regular rectangular shape, and therefore an irregular shape with respect to the current rhombus or a triangle, it can be improved into a ho linearity. [0146] 本领域技术人员可以理解,对于感应单元2来说,只要感应本体20的长度满足触摸检测组件要求,且两端电极分别与控制芯片200的不同的管脚相连以能够对感应单元进行充电和放电即可,因此可以看出本实用新型并不限制感应单元的具体结构。 [0146] Those skilled in the art will be appreciated, the sensing unit 2 For as long as the length of the sensor body 20 to meet the requirements of the touch detection component, and both ends of the pin electrodes are connected to different control chip 200 to enable each of the sensing unit to charge and discharge, and therefore can be seen that the present invention is not limited by the specific configuration of the induction unit. 感应单元可以有多种结构,本领域技术人员可在本实用新型上述思想的基础上对感应单元进行变化或者改进,但是只要未脱离本实用新型的上述思想这些结构就应包含在本实用新型的范围之内。 The sensing unit may have various structures, one skilled in the art can change or induction unit according to the present invention is improved based on the above idea, but as long as the present invention described above without departing from the thought of these structures should be included in the present invention within range.
