Description

触摸屏检测设备、触控装置及便携式电子设备 Touch screen detection device, the touch device and the 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,特别涉及一种触摸屏检测设备及触控装置、便携式电子设备。 [0001] The present invention relates to the design and manufacturing technology of electronic devices, and particularly relates to a touch panel device and a touch detection apparatus, the portable electronic device.

背景技术 Background technique

[0002]目前触摸屏的应用范围从以往的银行自动柜员机,工控计算机等小众商用市场,迅速扩展到手机,PDA (个人数字助理),GPS (全球定位系统),PMP (MP3,MP4等),甚至平板电脑等大众消费电子领域。 [0002] Currently the scope of application of the touch screen of automatic teller machines from the previous bank, industrial computer and other niche commercial market, the rapid expansion of the mobile phone, PDA (personal digital assistant), GPS (Global Positioning System), PMP (MP3, MP4, etc.), even tablet PCs and other mass consumer electronics. 用于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迅速在便携式设备中得到了广泛应用。 A touch screen for touch operation is simple, convenient and user-friendly advantages, so the touch screen interface is expected to become the best human-computer interaction and rapid has been widely used in portable devices.

[0003] 电容触摸屏通常被分为自电容和互电容两类。 [0003] The capacitive touch screen are generally divided into two types of self capacitance and mutual capacitance. 如图I所示,为现有技术中常见的一种自电容触摸屏的结构图。 As shown in FIG. I, the prior art is a common configuration diagram of a self-capacitance touch screen. 该自电容触摸屏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做为触摸坐标。 The capacitance touch screen rhombus structure mainly bilayer 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 intersections of rows and columns as the touch coordinates. 虽然该自电容触摸屏的线性度较好,但是经常有鬼点出现,难以实现多点触摸。 Although self-linearity of the capacitive touch screen is better, but often point ghosts appear, it is difficult to achieve multi-point touch. 此外,由于采用双层屏,也会导致结构及成本大幅增加,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, and can lead to a substantial increase in construction costs, and the diamond structure in a small amount of capacitance change happens coordinate drifted outside interference big impact.

[0004] 如图2a所示,为现有技术中常见的另一种自电容触摸屏的结构图。 As shown in [0004] Figure 2a, the prior art is another configuration diagram of a self-capacitance touch screen common. 该自电容触摸屏采用三角形图形屏结构。 The capacitance touch screen panel structure triangular pattern. 该自电容触摸屏包括基板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'。 A plurality of triangular sensing units of the self-capacitance touch screen 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 '. 如图2b所示,为三角形自电容触摸屏的检测原理。 2b, the detection principle of a triangular self-capacitance touch screen. 如图所示,椭圆表示手指,S1、S2表示手指与两个三角形感应单元的接触面积。 As shown, a finger is elliptic, S1, 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/(S1+S2)*P,其中,P为分辨率。 Assumed that the coordinate origin at the lower left, the abscissa X = S2 / (S1 + S2) * P, wherein, P is the resolution. 当手指向右移动时,由于S2不是线性增大,所以X坐标存在一个偏差。 When the finger is moved rightward, since the increase in S2 it is not linear, there is a deviation of the X coordinate. 从上述原理可以看出,目前的三角形感应单元是单端检测,即只从一个方向检测,然后通过算法算出两个方向的坐标。 As can be seen from the above principle, the triangular sensing current detecting unit is a single-ended, i.e., detects only from one direction, then the coordinates of two directions is calculated by the algorithm. 虽然该自电容触摸屏结构更为简单,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。 Although the self-capacitance touch screen structure is more simple, but not optimized for capacitive sensing screen, a small amount of capacitance variation, leading to noise ratio is not enough. 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增大,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 lateral movement of the finger area is not linearly increased, thus the linearity is poor, resulting in the shifted coordinate calculation, linearity good enough.

[0005] 此外,该电容感应单元输出电容变化量很小,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。 [0005] In addition, the capacitive sensing cell output capacitance variation is small, 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.

[0010] 本实用新型实施例的触摸屏检测设备中的感应单元采用双端检测,即感应单元的两端均具有电极,且每个电极均与触摸屏控制芯片的对应管脚相连,在进行触摸检测时通过感应単元自身即可实现对触摸点的定位。 [0010] The touch screen detection apparatus according to the present invention embodiment dual sensing unit of the detector, i.e., both ends of the sensing unit has the electrodes, and each electrode is connected with a corresponding pin of the touch screen control chip, the touch detection is performed when positioning itself can be realized by sensing the touch point radiolabeling element.

[0011] 此外,本实用新型实施例中的感应单元采用类似门形的结构,不仅结构简单,便于制作,所有引线都在同一边,设计方便,減少银浆成本并且制作容易,对减少生产成本有很大帮助。 [0011] Further, the present invention embodiment the sensing unit similar gate-shaped configuration, not only simple structure, ease of fabrication, all of the terminals are on the same side, to facilitate the design, reduce cost and easy to manufacture silver paste, to reduce production costs great help.

[0012] 更为重要的是,本实用新型通过计算第一电阻和第二电阻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吋,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,从而提高了測量精度,改善了线性度。 [0012] More importantly, the ratio between the present invention by calculating the first and second resistors is implemented to determine the touch position, and therefore with respect to the current design of diamond or triangular, because the touch position is determined inches, without calculated from the size of the capacitor, and from the size of the capacitor will not affect the accuracy of the touch position, thus improve the measurement accuracy, improved linearity. 此外,由于本实用新型实施例的第一部分、第二部分和第三部分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,也可以进ー步地提高线性度。 Further, since the first part of this embodiment of the invention, the second and third portions can be of any number ー regular rectangular shape, and therefore an irregular shape with respect to the current rhombus or a triangle, it may be into step ー improved linearity.

[0013] 本实用新型实施例通过对感应单元两端的电极施加电平信号,如果该感应单元被触碰,手指或其他触摸物则会和感应单元形成自电容,因此本实用新型通过施加的电平信号可对该自电容进行充电,井根据第一电阻和第二电阻之间的比例关系确定触摸位置。 [0013] Example embodiment of the present invention is applied to the electrodes by a signal level at both ends of the sensing unit, if the sensing unit is touched, a finger or other touch object and the sensing unit will form a self-capacitance, thus electrically by applying the present invention the level of the signal from the capacitor can be charged well by the ratio of the touch position is determined between the first and second resistors. 例如在本实用新型的一个实施例中,第一电阻和第二电阻之间的比例关系根据在对所述自电容充电和/或放电时,从所述第一电极和/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。 For example, the ratio between the embodiment, the first and second resistors, and based on the self-capacitance or charging / discharging, from the first electrode and / or the second electrode in an embodiment of the present invention a first proportional relationship between the detected value and a second detection value obtained is calculated. 因此从第一电极和/或第二电极检测该自电容充电和/或放电时产生的第一检测值和第二检测值。 Thus the self and / or a first detected value and the second detection value or the time of discharge from the first capacitor charging electrode and / or the second detection electrode. 这样,通过第一检测值和第二检测值就能够反应触摸点位于该感应单元的位置,从而确定触摸点在触摸屏的位置。 Thus, by detecting a first value and the second value can be detected at a position of the touch point reaction sensing unit, to determine the location of a touch point in the touch screen. [0014] 本实用新型实施例提出了一种新颖的自电容检测方式,在感应单元被触摸时,触摸点就可将该感应单元分为两个电阻,从而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单元上的位置。 [0014] Example embodiment of the present invention, a novel self-capacitance detection method, when the sensing unit is touched, the touch point sensing unit can be divided into two resistors, thereby performing simultaneously the capacitance detection from this consideration two resistors can determine the position of the sensing unit on the touch point. 本实用新型实施例的结构简单,并且对于一个感应单元来说,可从其的第一电极和/或第二电极进行充电或放电,并在充电和/或放电时进行检测,不仅能够降低RC常数,节省时间提高效率,并且还能够保证坐标不会偏移。 Simple structure embodiment of the present invention, and for a sensing unit, the first electrode and / or the second electrode may be charged or discharged therefrom, and charging and / or discharging time of detecting not only possible to reduce the RC constant, save time and improve efficiency, and also to ensure that coordinates do not. 此外,本实用新型实施例还可以有效提高电路的性噪比,降低电路噪声,提高感应线性度。 Further, the present invention further embodiment can improve signal to noise ratio of the circuit, the noise reduction circuit, enhance the response linearity. 并且,在检测过程中由于对被触摸的感应单元进行充电,因此其中会产生小电流,能够很好地消除Vcom电平信号对触摸屏中感应单元产生的自电容的影响,因此可以相应地消除屏幕屏蔽层及相关工序,从而可以在增强了抗干扰能力的同时进一步降低成本。 And, during the detection process due to the touch sensing unit is charged, and therefore which produces a small current, perfectly eliminate self-capacitance impact Vcom level signal touchscreen induced generation unit, it is possible to correspondingly eliminate screen shield and related processes, the cost can be further reduced while the interferences.

具体实施方式 Detailed ways

[0026] 下面详细描述本实用新型的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。 [0026] The following detailed embodiments of the present invention described embodiments, exemplary embodiments of the embodiment shown in the accompanying drawings, wherein same or similar reference numerals designate the same or similar elements having same or functionally similar elements. 下面通过参考附图描述的实施例是示例性的,仅用于解释本实用新型,而不能解释为对本实用新型的限制。 By following with reference to the embodiments described are exemplary only for explaining the present invention, not be construed to limit the utility of this novel pair.

[0027] 本实用新型实施例提出了一种新颖的自电容检测方式,在感应单元被触摸时,触摸点可以将该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单元上的位置。 [0027] Example embodiment of the present invention, a novel self-capacitance detection method, when the sensing unit is touched, the sensing unit may be a touch point is divided into two resistors, capacitance detection is performed from consider both resistance can be determined on the position of the sensing unit of the touch point. 如图3所示,为本实用新型实施例触控装置的检测原理示意图。 3, the embodiment of the present novel detection principle schematic of practical embodiment of the touch device. 当手指触摸该感应单元时,相当于将该感应单元分割为两个电阻,这两个电阻的阻值与触摸点的位置相关。 When a finger touches the sensing unit, the sensing unit is equivalent to dividing the two resistors, the resistance associated with the position of a touch point of these two resistors. 例如,如图所述,当触摸点与第一电极较近时,则电阻Rl就较小,而电阻R2就较大;反正,当触摸点与第二电极较近时,则电阻Rl就较大,而电阻R2就较小。 For example, as described, when the touch point is close to the first electrode, the resistance Rl on the small and the large and resistor R2; Anyway, when the touch point closer to the second electrode, the resistance Rl on the more large, and the resistance R2 is small.

[0028] 因此,本实用新型通过对电阻Rl和R2的检测就可以确定触摸点在该感应单元上的位置。 [0028] Accordingly, the present invention is by detecting resistors Rl and R2 can determine the position of the touch on the sensing unit. 在本实用新型的实施例中,可通过多种方式检测电阻Rl和R2,例如可通过检测第一电极和第二电极的电流检测值、自电容检测值、电平信号检测值和电荷变化量中的ー种或多种,从而根据这些检测值获得电阻Rl和R2。 In an embodiment of the present invention may be a variety of ways by sensing resistor Rl and R2, for example, by detecting a first electrode and a current detection value of the second electrode from the capacitance detection value, the level signal and the charge variation amount detection value the ー or more, thereby obtaining a resistor Rl and R2 based on these detected values. 另外,在本实用新型的实施例中,检测可在充电时进行(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 can be performed (i.e., detection value to obtain the first charge and the second charge detection value) at the time of charging, may be performed (i.e., detection value to obtain a first and a second discharge in the discharge discharge detection value).

[0029] 此外,在充电和放电时进行的检测可以采用多种方式。 [0029] Further, at the time of detection of the charge and discharge may be employed in various ways. 但是需要说明的是,充电、放电或者检测中至少有ー个步骤是对第一电极和第二电极进行的,这样才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。 It should be noted, however, charging, discharging, or at least ー detecting step is carried out first and second electrodes, so that it is possible to obtain 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、放电或检测时需要有电流经过第一电阻和第二电阻,这样检测到的第一检测值和第二检测值才能够反应第一电阻和第二电阻之间的差值。 That is, the charging or discharging current detection when necessary through the first and second resistors, so that the detection value detected by the first and the second detected value capable of reacting only difference between the first and second resistors value.

[0030] 在本实用新型的实施例中,通常需要充两次电(包括同时对第一电极和第二电极充电的情況),以及两次检测。 [0030] In the present embodiment of the invention, it is generally necessary electrical twice (including the case of simultaneously charging the first and second electrodes), and two tests. 在一些实施例中,还可能会进行两次放电。 In some embodiments, it may also be two discharges. 在以下的实施例中均是进行两次充电及两次检测,在以下的实施例中不再赘述。 In the following embodiments are charged twice and detected twice, omitted in the following embodiments. 在此需要说明的是,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。 Note that here, twice and twice the charge that the present invention only detects embodiment 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,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。 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 a first charging resistor in accordance with the first detection value and the detected value of the second charge, then according to the first calculating a second charging resistor and a charging detection value detected value for the third time.

[0031] 具体地,本实用新型包括但不限于以下几种测量方式进行检测: [0031] In particular, the present invention include but are not limited to, the following detection measurement:

[0032] I、先向感应单元的第一电极和第二电极施加电平信号以对自电容充电(如果该感应单元被触摸则就会产生自电容);接着从第一电极和/或第二电极进行充电检测以获得第一充电检测值和第二充电检测值。 [0032] I, the first and second electrodes Xianxiang sensing unit level signal applied to the self-charge the capacitor (if the sensing unit is touched by the self-capacitance is generated); then a first electrode and / or from the second detecting second electrode 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和第二电极进行的,因此对于检测来说既可以从第一电极进行检测,也可以从第二电极进行检测,或者也可从第一电极和第二电极分别进行检测。 In this embodiment, since the charging is performed from the first electrode and the second electrode, it may be performed for the detection of the first detection electrode, the detection may be performed from the second electrode, or may be from the first electrode and the second electrodes is detected.

[0033] 还需要说明的是,在该实施例中,对第一电极和第二电极的充电可同时进行,也可分别进行,例如在第一电极和第二电极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,第一电极和第二电极施加的电平信号也可以不同;或者,也可以先在第一电极上施加ー个电平信号,之后再在第二电极上施加同一个电平信号或另ー个电平信号。 [0033] It is further noted that, in this embodiment, the charging of the first electrode and the second electrode may be performed simultaneously, may be performed separately, for example, the same level signal is applied simultaneously in the first and second electrodes in self-capacitance of the charge, in other embodiments, the first electrode and the second electrode is applied to the signal level may be different; or may be first applied ー a level signal on the first electrode, and then after the first level signal is applied on the same or another second electrode ー electrical signal level. 同样地,进行检测时既可以同时进行,也可分别进行。 Likewise, when the detection may be performed simultaneously, they may be performed separately. 在以下实施例中,充电、放电或检测均可同时进行,或者分别进行,在此不再赘述。 In the following examples, the charging, discharging, or may be detected simultaneously or separately, are not repeated here.

[0034] 2、向所述感应単元的第一电极或第二电极分别两次施加电平信号以对所述自电容进行两次充电;接着在毎次充电之后从所述第一电极和/或第二电极进行充电检测以获得所述第一充电检测值和第二充电检测值。 [0034] 2, the signal level is applied to the first electrode of the sensing element radiolabeling or the second electrodes to twice the self-capacitance charging twice; and then after every time from the first electrode and the charge / or the second electrode is charged to obtain the detected first and second charge-charge detection value detected value. 在该实施例中,由于充电是从第一电极或第二电极进行的,因此在检测时需要从第一电极和第二电极分别进行检测,其中,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 or the second electrode, so when detection is required from the first and second electrodes are detected, wherein the detection may be performed simultaneously, it may be performed separately.

[0035] 此外,在本实用新型的实施例中,还可以在第一电极进行两次充电,并从第一电极进行两次检测,或者,从第二电极进行两次充电,在第二电极进行两次检測。 [0035] Further, in the present embodiment of the invention, the first electrode can be charged twice, and two tests from the first electrode, or twice the charge from the second electrode, the second electrode two tests. 只要是,在两次充电时,分别将另ー个电极接地或接高阻以改变另ー个电极的状态。 As long as, in the two charging electrodes respectively ー another high impedance ground or to change the status of the other electrodes ー. 例如当向感应单元的第一电极分别两次施加电平信号以对自电容进行两次充电时,其中,两次充电中的一次将所述第二电极接地,另ー次将所述第二电极接为高阻;当向感应单元的第二电极分别两次施加电平信号以对自电容进行两次充电时,两次充电中的一次将所述第一电极接地,另ー次将所述第一电极接为高阻。 For example, when level signals are respectively applied to the two electrodes of the first sensing unit to charge the self-capacitance twice, wherein the two primary charging the second electrode is grounded, the other second sub ーis high impedance electrode; when the two are applied to the second electrode signal level sensing unit to charge the self-capacitance twice, once the first two charging electrode is grounded, the other secondary ー the said first electrode is a high impedance.

[0036] 这样即使是在第一电极进行了两次充电,由于第二电极状态的改变,也能够在第一电极进行两次检测,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。 [0036] Thus, even if the first electrode is charged twice, the second electrode due to a change of state, the detection can be performed twice in the first electrode, capable of reacting to obtain a first resistor between the second resistor R2 and Rl first detection value and the second detection value proportional relationship.

[0037] 3、向感应单元的第一电极和第二电极施加电平信号以对自电容充电;接着控制第一电极和/或第二电极接地以对自电容放电;之后从第一电极和/或第二电极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。 [0037] 3, a signal level applied to the first electrode and the second electrode of the sensing unit to charge the capacitor from the pair; then controls the first electrode / or the second electrode is grounded and a self-capacitance to discharge; and then from the first electrode / or second discharge detection electrodes 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和第二电极进行的,因此放电或检测就可从第一电极和/或第二电极进行。 In this embodiment, since the self capacitance is charged from the first electrode and the second electrode, the discharge or the detection can be carried out from the first electrode and / or the second electrode. 具体地,例如可同时向第一电极和第二电极施加电平信号以对自电容进行充电,或者也可不同时施加。 Specifically, for example, while applying a level signal to the first electrode and the second electrode of the capacitor is charged from, or may not be applied simultaneously. 在放电时两次放电可均将第一电极接地,或者均将第二电极接地。 When the discharge of the first two discharges may each electrode is grounded, or both the second ground electrode.

[0038] 4、向感应单元的第一电极或第二电极施加电平信号以对自电容充电;接着分别控制第一电极和第二电极接地以对自电容放电;之后分别从第一电极和/或第二电极进行放电检测以获得第一放电检测值和第二放电检测值。 [0038] 4, is applied to the first electrode or the second electrode unit sensing a level signal to the self charge the capacitor; then control the first and second electrodes a self-capacitance to ground to discharge; and then from the first electrode / or the second discharge electrodes 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和第二电极进行的,因此充电或检测就可从第一电极和/或第二电极进行。 In this embodiment, since the self-discharge capacitor is performed from the first electrode and the second electrode, or the charging detection can be carried out from the first electrode and / or the second electrode. 在该实施例中,两次充电也可均用第一电极,而将第二电极分别接地或接为高阻。 In this embodiment, two were also charged with a first electrode and the second electrode are grounded or connected to high impedance. 同样地,两次充电也可均用第二电极,而将第一电极分别接地或接为高阻。 Similarly, two were also charged with a second electrode, the first electrodes and the ground or to high impedance.

[0039] 5、向感应单元的第一电极或第二电极施加电平信号以对自电容充电;接着分别控制第一电极或第二电极接地以对自电容放电,之后分别从第一电极和第二电极进行放电检测以获得第一放电检测值和第二放电检测值。 [0039] 5, is applied to the first electrode or the second electrode unit sensing a level signal to the self charge the capacitor; then control the first or second electrode to ground to discharge from the capacitor, and then from the first electrode The second discharge electrodes 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和第二电极进行的,因此充电或放电就可从第一电极和/或第二电极进行。 In this embodiment, since the self-capacitance detection is performed from the first electrode and the second electrode, the charging or discharging can be performed from the first electrode and / or the second electrode. 在该实施例中,两次充电也可均用第一电极,而将第二电极分别接地或接为高阻。 In this embodiment, two were also charged with a first electrode and the second electrode are grounded or connected to high impedance. 同样地,两次充电也可均用第二电极,而将第一电极分别接地或接为高阻。 Similarly, two were also charged with a second electrode, the first electrodes and the ground or to high impedance.

[0040] 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和第二电阻之间的比例关系。 [0040] 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 and second resistors.

[0041] 需要说明的是,在本实用新型的实施例中,上述第一电极和第二电极的功能相同,且二者可以互换,因此在上述实施例中,既可以从第一电极检测也可以从第二电极检测,只要能满足在充电、放电或检测时需要有电流经过第一电阻和第二电阻这一要求即可。 [0041] Incidentally, in the present embodiment of the invention, the first electrode and the second electrode of the same functions, and both are interchangeable, so in the above embodiment, may be detected from the first electrode from the second electrode may be detected, as long as satisfying the charge or discharge current is detected when needed through the first and second resistors to this requirement.

[0042] 从上述描述中可以看出,对于本实用新型的上述充电及检测方式有很多种变化,但本实用新型的核心就是根据第一电阻和第二电阻之间的关系,例如比例关系或者其他关系来确定触摸点的位置。 [0042] As can be seen from the above description, there are many variations of the present invention and detecting the charging mode, but the present invention is based on the relationship between the core of the first and second resistors, for example, proportional relationship or other relationships to determine the position of the touch point. 进一步地,该第一电阻和第二电阻之间的关系需要通过自电容的充电和/或放电来检测。 Further, the relationship between the first and second resistors and capacitors need to self-charging / discharging or be detected by. 如果感应单元没有被触摸,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,对于此本实用新型实施例中会不断扫描,等待手指触摸到感应单元之后才开始计算,在此不再赘述。 If the sensor unit is not touched, the hand does not produce self-capacitance, self-capacitance thus detected data is small, the touch does not satisfy the determination condition, for this embodiment of the present invention will continue scanning, waiting for the finger touch after sensing unit to begin calculations are not repeated here.

[0043] 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测。 [0043] 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.

[0044] 另外还需要说明的是,上述检测方式仅为本实用新型的一些优选方式,本领域技术人员还可根据上述思想进行扩展或修改,这些均应包含在本实用新型的保护范围之内。 [0044] It also should be noted that the above embodiment merely detecting invention present some preferred, those skilled in the art may also be extended or modified in accordance with the above idea, which should be included within the scope of protection of the present invention .

[0045] 如图4a所示,为本实用新型实施例触摸屏检测设备结构图。 As shown in [0045] FIG. 4a, embodiments of the present novel configuration diagram of a touch screen detecting apparatus practical. 该触控装置包括基板100、多个不相交的感应单元200。 The touch device comprises a substrate 100, a plurality of disjoint sensing unit 200. 且多个感应单元200的每个均具有第一电极210和第ニ电极220。 And each of the plurality of sensing units 200 each having a first electrode 210 and the electrode 220 of Ni. 在本实用新型的实施例中,基板100为单层基板。 In the embodiment of the present invention, the substrate 100 is a single-layer board. 在该实施例中,该感应单元200可为门形,且多个感应单元200中每个感应单元200的长度不同,多个感应单元200之间相互嵌套。 In this embodiment, the sensing unit 200 may be a gate-shaped, and the length of each of the various sensing units 200 of the plurality of sensing units 200, a plurality of sensing cells 200 nest with each other. 其中,每个所述感应単元包括第一部分230、不相交的第二部分240和第三部分250。 Wherein each of said sensing element comprising a first portion radiolabeling 230, 240 do not intersect the second portion and a third portion 250. 优选地,第一部分230与基板100的第一边110平行,第二部分240和第三部分250与基板100的第二边120平行,且第二部分240 —端与第一部分230的一端相连,第三部分250的一端与第一部分230的另一端相连。 Preferably, the first portion 230 of the substrate 110 parallel to the first side 100, second side 120 parallel to the substrate 250 and a third portion 100 of second portion 240, and a second portion 240 - a first end connected to one end portion 230, end of the third portion 250 connected to the other end of the first portion 230. 感应单元200的第二部分240的另一端具有第ー电极210,第三部分250的另一端具有第二电极220,其中,姆个第一电极210和第二电极220均与触摸屏控制芯片的对应的管脚相连。 The other end of the second portion 200 of the sensing unit 240 has a first ー electrode 210, the other end of the third portion 250 having a second electrode 220, wherein the first electrodes Farm 210 and the second electrode 220 both correspond to the touch screen control chip connected to pins.

[0046] 在本实用新型的实施例中,所谓相互嵌套是指外侧的感应单元部分地包围内侧的感应单元,例如如图4a所示,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,提高触摸屏的响应速度。 [0046] In an embodiment of the present invention, the term nested refers to the outside part surrounding the sensing unit inside the sensing unit, for example, shown in Figure 4a, this can achieve a greater precision at the same time to ensure coverage and reduce computational complexity, improve the response speed of the touch screen. 当然本领域技术人员还可根据图4a的思想采用其他相互嵌套的方式排列感应单元。 Of course, those skilled in the art may use other are arranged nested into each other according to the sensing unit of FIG. 4a thought. 在本实用新型的一个实施例中,每个感应单元200的第一部分230与其他感应单元200的第一部分230平行,每个感应单元200的第二部分240 与其他感应单元200的第二部分240平行,每个感应单元200的第三部分250与其他感应单元200的第三部分250平行。 Embodiment, each sensor unit in parallel with other sensors 230,230 units of the first portion 200 of the first portion 200 in one embodiment of the present invention, the second portion 240 of each second portion 200 of the sensing unit 240 sensing unit 200 with the other parallel, each sensing cell 200 third portion 250 of the other sensing unit 250 of the third portion 200 in parallel. 在本实用新型的一个实施例中,感应单元200的第一部分230、第二部分240和第三部分250中至少ー个为矩形,优选地,第一部分230、第二部分240和第三部分250均为矩形。 In one embodiment of the present invention embodiment, the sensing unit 200 of the first portion 230, second portion 240 and third portion 250 of at least one rectangular ー, preferably, the first portion 230, second portion 240 and third portion 250 They are rectangular. 在该实施例中,由于矩形结构图形规则,因此在手指横向或纵向移动时线性度好,此外,两个矩形结构之间的间距相同,便于计算。 In this embodiment, since the pattern rule a rectangular structure, and therefore a good horizontal or vertical movement of the finger when the linearity, in addition, the distance between two identical rectangular structure, easy to calculate.

[0047] 本实用新型实施例的触摸屏检测设备中的感应单元采用双端检测,即感应单元的两端均具有电极,且每个电极均与触摸屏控制芯片的对应管脚相连,在进行触摸检测时通过感应単元自身即可实现对触摸点的定位。 Touch screen detection apparatus [0047] embodiment of the present invention in the embodiment uses the double end detection sensor unit, i.e., both ends of the sensing unit has the electrodes, and each electrode is connected with a corresponding pin of the touch screen control chip, the touch detection is performed when positioning itself can be realized by sensing the touch point radiolabeling element. 此外,本实用新型实施例中的感应单元采用类似门形的结构,不仅结构简单,便于制作,所有引线都在同一边,设计方便,減少银浆成本并且制作容易,对减少生产成本有很大帮助。 Further, the present invention embodiment the sensing unit similar gate-shaped configuration, not only simple structure, ease of fabrication, all of the terminals are on the same side, to facilitate the design, reduce cost and easy to manufacture silver paste, greatly reducing the cost of production help.

[0048] 更为重要的是,本实用新型通过计算第一电阻和第二电阻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吋,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。 [0048] More importantly, the ratio between the present invention by calculating the first and second resistors is implemented to determine the touch position, and therefore with respect to the current design of diamond or triangular, because the touch position is determined inches, without calculated 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部分、第二部分和第三部分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 part of this embodiment of the invention, the second and third portions can be of any number ー regular rectangular shape, and therefore an irregular shape with respect to the current rhombus or a triangle, it may be into ho an improved linearity.

[0049] 在本实用新型的一个实施例中,每个感应单元200的第二部分240与第三部分250 [0049] In one embodiment of the present invention embodiment, the second portion 240 and third portion 200 of each sensing unit 250

长度相等。 Equal length.

[0050] 在本实用新型的一个实施例中,基板100为矩形,第一边110和第二边120之间相互垂直,且第二部分240和第一部分230之间相互垂直,第三部分250和第一部分230之间 [0050] In one embodiment of the present invention embodiment, the substrate 100 is a rectangular, perpendicular to each other between a first side 110 and second side 120, and a second portion 240 perpendicular to each other and the first portion 230, third portion 250 and between the first portion 230

相互垂直。 Perpendicular to each other.

[0051] 在本实用新型的一个实施例中,相邻两个感应单元200的第一部分230之间的间距相等,相邻两个感应单元200的第二部分240之间的间距相等,相邻两个感应单元200的第三部分250之间的间距相等。 [0051] In one embodiment of the present invention embodiment, two adjacent sensing units 200 of the first portion 230 is equal to the distance between the equal spacing between the second portion 240 of two adjacent sensing units 200, adjacent equal to the spacing between the third portion 200 of the two sensing units 250. 这样就可以通过多个感应単元200对触摸屏的第一边110和第二边120均匀划分,从而提高运算速度。 This allows a plurality of induction by radiolabeling unit 200 to the first side 110 and second side 120 of the touch screen divided evenly, thereby increasing the operation speed. 当然在本实用新型的其他实施例中,相邻两个感应单元200的第一部分230之间的间距也可不相等,或者,相邻两个感应单元200的第二部分240之间的间距也可不相等,如图4b所示。 The spacing between the second portion 200 of the 240 in the present invention of course other embodiments, the spacing between two adjacent sensing units 200 of the first portion 230 may not be equal, or may not be adjacent to two sensing units are equal, as shown in Figure 4b. 例如,由于用户往往触摸触摸屏的中心部位,因此可以将触摸屏中心部位的感应单元之间的间距减小,从而提高中心部位的检测精度。 For example, since the user often touches the center portion of the touch screen, so the pitch can be between the central portion of the touch screen sensing unit is reduced, thereby improving the detection accuracy of the center portion.

[0052] 在本实用新型的一个实施例中,多个感应单元200位于同一层,因此只需要一层ITO即可,从而在保证精度的同时,极大地降低制造成本。 [0052] In one embodiment of the present invention, a plurality of sensing units 200 at the same level, it is only necessary to ITO layer, thus ensuring the accuracy, while greatly reducing the manufacturing cost.

[0053] 在本实用新型的一个实施例中,多个感应单元200相对于基板100的中心轴Y对称,如图4a所示,中心轴Y垂直于第一部分230,从而更有利于提高精度。 [0053] In one embodiment of the present invention, the plurality of sensing units 100 of the substrate 200 with respect to the central axis Y of symmetry, as shown, to improve the central axis Y perpendicular to the first portion 230, which is more conducive 4a accuracy.

[0054] 如图4a所示,在该实施例中,感应单元200的第一电极210和第二电极220均位于基板100的第一边110上。 As shown in [0054] FIG. 4a, in this embodiment, the first electrode 200 of the sensing unit 210 and the second electrode 220 are located on the first side 110 of the substrate 100. 在该实施例中,检测到在感应单元上的触摸位置之后,即可获得在触摸屏之上的触摸位置。 In this embodiment, after detecting the touch position on the sensing unit, the touch position can be obtained on the touch screen.

[0055] 需要说明的是,上述图4a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4a进行一些等同的变化,例如第二部分240和第三部分250也可以是不平行的。 [0055] Incidentally, the above-described novel preferable embodiment of the present practical FIG. 4a, which is possible to obtain a larger coverage, but the present invention may be made of some other embodiments of equivalent variations on FIG. 4a, for example, the first two parts 240 and the third portion 250 may be non-parallel.

[0056] 如图5所示,为本实用新型实施例的感应单元被触摸时的示意图。 As shown in [0056] FIG. 5, a schematic view of the sensor element is touched embodiment of the present invention. 从图5可知,第一电极为210,第二电极为220,触摸位置接近于第二电极,假设感应单元的长度为10个单位长度,且将感应单元均匀地分为10份,其中,感应单元第一部分230的长度为4个单位长度,感应单元第二部分240和第三部分250的长度为3个单位长度。 Seen from FIG. 5, a first electrode 210, second electrode 220, the touch position close to the second electrode, the length is assumed that the sensing unit 10 per unit length, and the sensing unit 10 is uniformly divided into parts, wherein the sensor unit length of the first portion 230 is four units of length, the length of the third portion 240 and second portion 250 of the sensing unit 3 per unit length. 经过检测,获知第一电阻和第二电阻之比为4:1,即第一电极210至触摸位置的长度(由第一电阻体现)为全部感应单元长度的80%。 After testing, the known ratio of the first resistor and the second resistor has a 4: 1, i.e., the length of the first electrode 210 to a touch position (embodied by a first resistor) is 80% of the total length of the sensing unit. 换句话说,触摸点位于距离第一电极210处8个单位长度的位置,获知,触摸点位于距离第二电极220处2个单位长度的位置。 In other words, the touch point located at a distance of 2,108 units of length of the first electrode, known, position of the touch point is located at a distance of 2,202 units of length of the second electrode.

[0057] 从图5的以上例子可以看出,本实用新型的计算方式非常简单,因此能够极大地提高触摸屏检测的反应速度。 [0057] As can be seen from the above example of Figure 5, the present invention is very simple calculation, it is possible to greatly improve the response speed of the touch screen detection. 如图6所示,为本实用新型一个实施例的触控装置示意图。 6, a schematic view of a touch device novel embodiment of the present invention. 该触控装置包括由基板100和多个不相交的感应单元200所构成的触摸屏检测设备300和触摸屏控制芯片400。 The touch device comprises a touch screen and a touch panel detection device 300 by the control chip substrate 100 and a plurality of disjoint sensing unit 200 is composed of 400. 其中,触摸屏控制芯片400中的一部分管脚与多个感应单元200的第一电极210相连,触摸屏控制芯片400中的另一部分管脚与多个感应单元200的第二电极220相连。 Wherein the touch panel control chip 400 and a portion of the plurality of sensing pins 200 of the unit 210 is connected to the first electrode, the second electrode is connected to another portion of the touch screen controller chip pins 400 and 220 of the plurality of sensing units. 触摸屏控制芯片400向多个感应单元200的第一电极210和/或第二电极220施加电平信号,该电平信号在感应单元200被触摸时向感应单元200产生的自电容充电,且触摸屏控制芯片400在检测到多个感应单元中一个或部分被触摸时,计算被触摸的感应单元200中第一电极210至自电容的第一电阻与第二电极220至自电容的第二电阻之间的比例关系,以及根据所述比例关系及被触摸的感应单元200计算触摸点坐标。 Touch screen control chip 400 to the plurality of sensing units 210 of the first electrode 200 and / or from the capacitor charge level of a signal applied to the second electrode 220, the sensing unit at the level of the signal generated when the touch sensing unit 200 to 200, and the touch screen control chip 400 detects a plurality of sensing units or a part is touched, the touch sensing unit is calculated 200 from the first electrode 210 to the first resistor and the second capacitor electrode 220 to the self-capacitance of the second resistor proportional relationship between, and the touch point coordinate is calculated according to the proportional relation and the sensing unit 200 is touched. 同样地,该充电、放电和检测可同时进行也可分别进行,在此不再赘述。 Similarly, the charging, discharging and detection may also be performed simultaneously, respectively, are not repeated here. 例如,参照图5所示,最外侧的感应单元被触摸,且触摸屏控制芯片400获得了最外侧感应单元的第一电阻和第二电阻的比例关系,由于最外侧感应单元的位置信息已存储在触摸屏控制芯片400中,当然也可存储在外接的存储器中,因此触摸屏控制芯片400就可以依据该比例关系查找最外侧感应单元的位置信息,从而确定触摸点坐标。 For example, referring to FIG. 5, the outermost sensing unit is touched, and the touch screen controller chip 400 obtains the ratio between the outermost first resistor and a second resistor sensing unit, since the outermost position information already stored in the sensing unit touch screen control chip 400, of course, also be stored in external memory, the touch screen control chip 400 can lookup the location information of the outermost sensing unit according to the proportional relationship, so as to determine the touch point coordinates.

[0058] 在本实用新型的实施例中,通常手指或其他物体会触摸多个感应单元,此时触摸屏控制芯片400可以先获得在这被触摸的多个感应单元中每个的触摸位置,然后通过求平均的方式计算最终在触摸屏上的触摸位置。 [0058] In an embodiment of the present invention, a finger or other object will typically touch sensing units, the control chip 400 that the touch screen can be obtained in a plurality of first sensing cells in each of which the touched touch position, then calculating a final touch position on the touch screen by way of averaging. [0059]另外,第一检测值和第二检测值可为电流检测值、自电容检测值、电平信号检测值和电荷变化量中的ー种或多种,只要能反应第一电阻和第二电阻之间的差值即可。 [0059] Further, the first detection value and the second value may be a current detection value detected from the capacitance detection value, the detection signal value and the variation amount of charge in ー level or more, as long as the reaction of the first and second resistors to the difference between the second resistor. 在本实用新型的一个实施例中,触摸屏控制芯片400之中包括两个电容检测器件CTS以同时从第ー电极210和第二电极220对感应单元200进行检测。 In one embodiment of the present invention embodiment, the touch screen controller chip 400 includes two among the capacitance detection means to simultaneously detect the CTS ー first electrode 210 and second electrode 220 to the induction unit 200. 由于这两个电容检测器件CTS可以共用ー些器件,因此也不会増加芯片的整体功耗。 Since the two capacitors CTS detection device can share ー these devices and therefore do not increase the overall power consumption of the chip zo.

[0060] 在本实用新型的另ー个实施例中,也可仅采用一个电容检测器件CTS依次从第一电极210和第二电极220对感应单元200进行检测。 [0060] In the present invention ー another embodiment may also be detected using only one capacitor means sequentially detects CTS from the first electrode 210 and second electrode 220 to the induction unit 200. 触摸屏控制芯片400根据第一电阻和第二电阻之间的比例关系确定触摸位置。 Touch screen control chip 400 determines a touch position according to the ratio relationship between the first and second resistors.
