触摸检测方法、触摸屏检测装置及触控装置 The method of detecting a touch, a touch screen and a touch detection device means

技术领域 FIELD

[0001] 本发明设及电子设备设计及制造技术领域,特别设及一种触摸检测方法、触摸屏及触控装置。 [0001] The present invention is provided and the design and manufacturing technology field of electronic devices, and particularly to a touch detecting method is provided, the touch screen and the touch device.

背景技术 Background technique

[0002] 目前触摸屏的应用范围从W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 from W to a bank ATM, 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.) and even the mass consumer electronics such as tablet computers. 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1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, 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W实现多点触摸。 Although self-linearity of the capacitive touch screen is better, but often point ghosts appear, W difficult to achieve multi-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Ξ角形图形屏结构。 The self capacitance touch screen with Ξ angled screen pattern structure. 该自电容触摸屏包括基板300'、设置在基板300'之上的多个Ξ 角形感应单元400'、和每个Ξ角形感应单元400'相连的多个电极500'。 The capacitance touch screen includes a substrate 300 ', disposed in the substrate 300' over a plurality of angled Ξ sensing units 400 ', each angled Ξ sensing unit 400' is connected to the plurality of electrodes 500 '. 如图化所示,为Ξ角形自电容触摸屏的检测原理。 As shown in FIG technology, the detection principle of angular Ξ self-capacitance touch screen. 如图所示,楠圆表示手指,S1、S2表示手指与两个Ξ角形感应单元的接触面积。 As illustrated, the circles represent the finger Nan, S1, S2 represents the contact area of ​​the finger with two angular Ξ sensing unit. 假设坐标原点在左下角,则横坐标X = S2/(S1+S2)冲,其中,P为分辨率。 Assumed that the coordinate origin at the lower left, the abscissa X = S2 / (S1 + S2) punch, wherein, P is the resolution. 当手指向右移动时,由于S2不是线性增大,所WX坐标存在一个偏差。 When the finger is moved rightward, since the increase in S2 is not linear, there is a deviation of the coordinate WX. 从上述原理可W看出,目前的Ξ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。 W can be seen from the above principle, the current sensing angular Ξ detection 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Ξ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 unit Ξ angular, lateral movement of the finger when the area is not increased linearly, so 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,杂散电容会随溫度、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.

[0011] 本发明实施例的触摸屏检测装置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忍片的对应管脚相连,在进行触摸检测时通过感应单元自身即可实现对触摸点的定位。 [0011] The touch panel detector of the embodiment of the present invention uses the double end detection sensor unit, i.e. the unit has induced across the electrodes, and each electrode is connected to corresponding pins of the chip tolerance touch screen control, the touch detection is performed when positioning itself can be realized by the sensing unit of the touch point.

[0012] 更为重要的是,本发明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Ξ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,从而提高了测量精度,改善了线性度。 [0012] More importantly, the present invention determines the touch position is achieved by calculating the ratio between the first and second resistors, and therefore with respect to the current design of diamond or angular Ξ, since in determining the touch position, 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.

具体实施方式 Detailed ways

[0030] 下面详细描述本发明的实施例,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。 [0030] Example embodiments of the present invention is described in detail below, exemplary embodiments of the embodiment shown in the accompanying drawings, wherein same or similar reference numerals designate the same or similar elements or elements having the same or similar functions. 下面通过参考附图描述的实施例是示例性的,仅用于解释本发明,而不能解释为对本发明的限制。 By following with reference to the embodiments described are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0031] 本发明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W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运两个电阻就可W确定触摸点在该感应单元上的位置。 [0031] Example A novel self-capacitance detection method of the present invention, when the sensing unit is touched, the touch point sensing unit W can be divided into two resistors, capacitance detection is performed from the operation taking two W resistor to determine the position of the touch on the sensing unit. 如图3所示,为本发明实施例触控装置的检测原理示意图。 3, a schematic view of the principle of the detection device of embodiments of the present invention the touch. 当手指触摸该感应单元时,将相当于将该感应单元分割为两个电阻,运两个电阻的阻值与触摸点的位置相关。 When a finger touches the sensing means, the sensing means corresponding to the division of two resistors, the resistance associated with the touch position of the operation point of the two resistors. 例如,如图所述,当触摸点与第一电极较近时,则电阻R1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R1就较大,而电阻R2就较小。 For example, as described, when the touch point is close to the first electrode, to the resistor R1 is small, while larger and resistor R2; Anyway, when the touch point closer to the second electrode, the resistance R1 on the more large, and the resistance R2 is small. 因此,本发明通过对电阻R1和R2的检测就可W确定触摸点在该感应单元上的位置。 Accordingly, the present invention is by detecting resistors R1 and R2 determine the position of W can touch point on the sensing unit. 在本发明的实施例中,可通过多种方式检测电阻R1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一种或多种,从而根据运些检测值获得电阻R1和R2。 In an embodiment of the present invention may be detected in various ways by resistors R1 and R2, for example, by detecting a first electrode and a current detection value of the second electrode, the capacitance value of the detection, the detection level signal and the charge value from the amount of change in one or more, to obtain the resistors R1 and R2 in accordance with operation of these detection values. 另外,在本发明的实施例中,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 embodiment of the present 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 discharge and the second discharge in the discharge detection value). 此外, 在充电和放电时进行的检测可W采用多种方式。 Further, at the time of detection of charge-discharge W and a variety of ways. 但是需要说明的是,充电、放电或者检测中至少有一个步骤是对第一电极和第二电极进行的,运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 detecting at least one step is carried out first and second electrodes, the sample transport able 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,运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, the sample transport detected first detection value and the second value to be able to detect a reaction between the first and second resistors difference. 在本发明的实施例中,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况),W及两次检测。 In an embodiment of the present invention, it is generally necessary to electrically twice (including the case of simultaneous first and second electrodes of the charge), W 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W下的实施例中均是进行两次充电及两次检测,在W下的实施例中不再寶述。 In an embodiment of W, it is at twice the charge and detected twice, not described in the embodiment of the Po and W. 在此需要说明的是,进行两次充电及两次检测仅是本发明实施例的一种方案,算法相对比较简单。 Note that here, twice and twice the charge detection is only one aspect of an embodiment of the present invention, the algorithm is relatively simple. 然而本领域技术人员也可根据上述思想增加充电及检测的次数,例如可进行Ξ次充电和检,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Ξ次的充电检测值计算第二电阻。 Those skilled in the art may also be increased based on the number of charge and Thought detected, for example, may be the subject Ξ charge and, after calculating a first charging resistor in accordance with the detected value of the first and second charge detected value, and then in accordance with calculating a second charge of the first resistance value and the detected value of the charge detection Ξ times.

[0032] 具体地,本发明包括但不限于W下几种测量方式进行检测: [0032] In particular, the present invention includes but is not limited to be detected at several measurement W:

[0033] 1、先向感应单元的第一电极和第二电极施加电平信号W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W获得第一充电检测值和第二充电检测值。 [0033] 1, Xianxiang sensing unit of the first electrode and the second electrode is applied to the W-level signal from the capacitor charge (if the sensing unit is touched by the self-capacitance is generated); then from the first electrode and / or the second electrode charging detection value W obtained a first charge and the second charge detection value detected. 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W从第一电极进行检测,也可W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, for detecting either W is detected from a first electrode, W can be detected from the second electrode, or may be from a and the second electrode are detected. 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W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W 不同;或者,也可W先在第一电极上施加一个电平信号,之后再在第二电极上施加同一个电平信号或另一个电平信号。 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 of a signal applied to the self-W simultaneously in the first and second electrodes capacitor is charged, in other embodiments, the first electrode and the second level signal W applied to the electrodes may be different; or W may be a first level signal is applied to the first electrode, the second electrode after further level signal is applied to the same or another signal level. 同样地,进行检测时既可W同时进行,也可分别进行。 Similarly, when W can be detected simultaneously, it may be performed separately. 在W下实施例中,充电、放电或检测均可同时进行,或者分别进行,在此不再寶述。 W In the embodiment, the charging, discharging, or may be detected simultaneously or separately, which is not described treasure.

[0034] 2、向所述感应单元的第一电极或第二电极分别两次施加电平信号W对所述自电容进行两次充电;接着在每次充电之后从所述第一电极和/或第二电极进行充电检测W获得所述第一充电检测值和第二充电检测值。 [0034] 2, W-level signal is applied to the first electrode of the sensing unit or the second electrodes from the capacitor recharges twice; and then after each charge from the first electrode and / or the second electrode charging W detected value to obtain the first charge and the second charge detection value detected. 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. 此外,在本发明的实施例中,还可W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测。 Further, in the embodiment of the present invention, the first electrode may be W is charged twice, and twice from the first detecting electrode, or twice the charge from the second electrode, the second electrode twice detection. 只要是,在两次充电时,分别将另一个电极接地或接高阻W改变另一个电极的状态。 As long as, in the two charging, respectively, change the state of the other electrode of the other electrode is grounded or connected to a high-impedance W. 例如当向感应单元的第一电极分别两次施加电平信号W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,另一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W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, 另一次将所述第一电极接为高阻。 For example, when level signals are respectively applied to two W to the first electrode from the capacitance sensing unit to be charged twice, wherein the two primary charging the second electrode is grounded, and once the second electrode connected to high impedance; when the two are applied to the level signal W to the second electrode from the capacitance sensing unit to be charged twice, once to twice said first electrode is grounded in the charging, and once the first a high impedance electrode. 运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,W获得能够反应第一电阻R1和第二电阻R2 之间比例关系的第一检测值和第二检测值。 Even the sample transport in the first two charging electrodes, the second electrode due to a change of state, the detection can be performed twice in the first electrode, W the reaction can be obtained proportional relation between the first resistor R1 and second resistor R2 a first detection value and the second detection value. 3、向感应单元的第一电极和第二电极施加电平信号W对自电容充电;接着控制第一电极和/或第二电极接地W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W获得所述第一放电检测值和第二放电检测值。 3, is applied to the first electrode and the second electrode unit sensing a level signal W to the self-capacitance charge; then controls the first electrode and / or the second ground electrode W of the self-discharge capacitor; then from the first electrode and / or the two discharge detection electrodes W obtained detection value of the first discharge and the second discharge detection 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W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 W and the second electrode to the first 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.

[0035] 4、向感应单元的第一电极或第二电极施加电平信号W对自电容充电;接着分别控制第一电极和第二电极接地W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W获得第一放电检测值和第二放电检测值。 [0035] 4, signal W is applied to the level of charge on the capacitor from the second electrode to the first electrode or the sensing unit; then control the first and second electrodes of the self-grounding capacitor discharge W; and then from the first electrode / or second discharge detection electrodes W discharge detection value to obtain a first detected value and the second discharge. 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.

[0036] 5、向感应单元的第一电极或第二电极施加电平信号W对自电容充电;接着分别控制第一电极或第二电极接地w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W获得第一放电检测值和第二放电检测值。 [0036] 5, W-level signal is applied to the capacitor from the charging electrode to the first electrode or the second sensing unit; then control the first electrode or the second electrode is grounded w self-discharge capacitor, and then from the first electrode The second discharge electrode discharge detection to obtain a first detected value W and the second 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.

[0037] 或者,在上述实施例的基础之上,还可W在充电时进行一次检测W获得第一充电检测值,在放电时进行第二次检测W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。 [0037] Alternatively, in the above embodiment of the above embodiment, a test is W W may obtain a first detected value of the charge, a second W detection at the time of discharge to obtain a second detected value during charge and discharge, and then in accordance with the first a detection value and the second charge-discharge detection value obtained proportional relation between the first and second resistors.

[0038] 需要说明的是,在本发明的实施例中,上述第一电极和第二电极的功能相同,且二者可W互换,因此在上述实施例中,既可W从第一电极检测也可W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运一要求即可。 [0038] Incidentally, in the embodiment of the present invention, the first electrode and the second electrode of the same functions, and both W can be interchanged, so in the above-described embodiments, both W from the first electrode W may also be detected from the second detection electrode, as long as it satisfies the charging or discharging current detection when necessary through the first and second resistors to operational requirements a.

[0039] 从上述描述中可W看出,对于本发明的上述充电及检测方式有很多种变化,但本发明的核屯、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。 [0039] W can be seen from the above description, there are many variations of the charging and the detection of the present invention, but the present invention Tun nucleus is the relationship between the first and second resistors, for example, the ratio between 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,对于此本发明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,在此不再寶述。 If the sensor unit is not touched, the hand does not produce self-capacitance, self-capacitance thus detected data is small, the determination condition is not satisfied touch, for this embodiment of the present invention will continue scanning, waiting for the finger touch after calculation began sensing unit, which is not described treasure.

[0040] 在本发明的实施例中,可扫描的方式依次向多个感应单元施加相应的电压, 同时在检测时也可扫描的方式依次进行检测。 [0040] In an embodiment of the present invention may be applied sequentially in a scanning manner corresponding to the plurality of voltage sensing unit, while the detection may also be detected sequentially scanning manner.

[0041] 另外还需要说明的是,上述检测方式仅为本发明的一些优选方式,本领域技术人员还可根据上述思想进行扩展或修改,运些均应包含在本发明的保护范围之内。 [0041] It also should be noted that the detection of only some preferred embodiment of the present invention, those skilled in the art may also be extended or modified in accordance with the above idea, some transport should be included within the scope of the present invention.

[0042] 如图4所示,为本发明实施例的触摸检测方法流程图,该流程图结合图3所示的原理图一同进行说明。 [0042] As shown in FIG 4, the touch detecting method of the present invention, an embodiment of a flow chart, showing the principle in conjunction with the flowchart shown in FIG. 3 will be described together. 该方法包括W下步骤: The method comprises the steps of W:

[0043] 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和/或第二电极施加电平信号。 [0043] step S401, the signal is applied to both ends of the level sensing means, namely a first sensing electrode unit and / or the second electrode is applied to the signal level. 在该实施例中,可向第一电极和第二电极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 and the second electrode, may be applied to different signal levels. 在其他实施例中,也可仅从第一电极或第二电极进行充电两次,或者第一次从第一电极充电第二次从第二电极充电,或者第一次从第二电极充电第二次从第一电极充电。 In other embodiments, may be performed only from the first or second electrode charging twice, the first or second charge charge from the first electrode from the second electrode, or from the second electrode of the first charge secondary charge from the first electrode.

[0044] 如果此时该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C1 (参照图3),通过施加的电平信号就可对自电容进行充电。 [0044] At this time, if the sensing unit is touched with a finger or other object, the sensing unit will be generated from the capacitor C1 (see FIG. 3), since the capacitor can be charged for by the level of the signal applied. 在本发明的实施例中,通过对自电容的充电,可W提高自电容的检测精度。 In an embodiment of the present invention, by charging the self-capacitance, W can improve the detection accuracy of the self-capacitance.

[0045] 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同时从感应单元的两端进行检测。 [0045] Incidentally, if a signal is applied to both ends of the level sensing unit simultaneously, then the corresponding two capacitors required detection module detects CTS simultaneously from both ends of the sensing unit. 而如果分别向两端时间的话,则仅需要一个电容检测模块CTS即可。 If both ends of the time respectively, then only one capacitance detection module to CTS. 在本发明的一个实施例中,第一检测值和第二检测值可W为从第一电极和/或第二电极检测到的电容电荷变化量A Q1和Δ Q2。 In one embodiment of the present invention, the first detection value and the second value may be W is detected from the first electrode and / or the second electrode to detect capacitive charge variation amount A Q1 and Δ Q2. 通过Δ Q1与Δ Q2,即检测到得自电容变化量,就可W算出R1与R2的比例,由于图形的规则线性关系,则可W算出触摸点所在的横坐标的位置,及自电容C1所在的位置。 By Δ Q1 and Δ Q2, i.e., from the detected capacitance variations, the ratio of R1 and R2 can be calculated from W, since the rules of linear pattern, the position of the abscissa where the touch point may be calculated by W, and the capacitor C1 from It is located.

[0046] 步骤S402,从感应单元的两端对感应单元进行检测,W获得第一检测值和第二检测值。 [0046] step S402, the detection unit of the sensing ends of the sensing unit, W 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A Q1和Δ Q2。 In the above example, the first detection value and the second detection values ​​of A Q1 and Δ Q2. W下W第一检测值和第二检测值为电荷变化量为例进行描述,但是能够反应电阻R1和R2关系的其他检测值,例如电平信号、电流等也均可采用。 W W at a first value and a second detection value detected variation amount of charge will be described as an example, it is possible to detect the reaction of other values ​​of resistors R1 and R2 relations, e.g. level signal, current, etc. can be employed. 在本发明的实施例中,既可W同时检测,也可W分别检测。 In an embodiment of the present invention, simultaneous detection of either W, W may be separately detected.

[0047] 在本发明的一个实施例中,如果进行同时检测,则需要两个自电容触摸屏控制忍片同时对第一电极和第二电极进行检测。 [0047] In one embodiment of the present invention, if the simultaneous detection, then two self-capacitance touch screen control tolerance sheet while the first electrode and the second electrode is detected.

[0048] 在本发明的另一个实施例中,也可采用一个自电容触摸屏控制忍片进行检测,参照步骤S401中,在通过第一电极对自电容C1充满之后,即该自电容触摸屏控制忍片通过第一电极对自电容C1进行检测。 [0048] In another embodiment of the present invention may also be employed to control a self-capacitance touch screen detects tolerance sheet, with reference to step S401, tolerance by the first electrode pair since the capacitor C1 is charged, i.e. the self-capacitance touch screen control sheet be detected from the capacitor C1 through the first electrode. 接着再通过第二电极对自电容C2充电,接着该自电容触摸屏控制忍片再通过第二电极对自电容C1进行检测。 Followed by self charging the capacitor C2 through the second electrode, followed by the self-capacitance touch screen control tolerance sheet again from the capacitor C1 is detected by a second electrode.

[0049] 由于自电容触摸屏控制忍片扫描该感应单元时采用的相位和电平信号均一致,因此对于同一个自电容C1来说充电时的电荷就等于它们电阻的反比。 [0049] Since the capacitance touch screen controls the phase and level of the scanning signal used to endure sheet sensing unit are consistent, so for the same charge at the charge from the capacitor C1 is inversely proportional to the resistance thereof is equal. 假设,从感应单元的第一电极和第二电极对感应单元检测获得的电荷变化量分别是A Q1与Δ Q2。 Suppose, from the charge variation amount of the first and second electrodes of the sensing unit of the sensing unit detects A Q1 are obtained with Δ Q2. 在本发明的实施例中,自电容触摸屏控制忍片可为目前已知的自电容触摸屏控制忍片。 In an embodiment of the present invention, the self-capacitance touch screen control tolerance can be tolerated sheet piece currently known self capacitance touch screen control. 在本发明的一个实施例中,如果采用两个自电容触摸屏控制忍片的话,则由于两个自电容触摸屏控制忍片可工艺多个器件,因此不会增大忍片的整体功耗。 In one embodiment of the present invention, if two capacitance touch screen, then the control tolerance sheet, since the two capacitance touch screen control process can tolerate a plurality of sheet components, it will not tolerate an increase in overall power consumption sheet.

[0050] 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。 [0050] step S403, the detection value based on the first detected value and determining whether the second sensing unit is touched. 具体地,在本发明的一个实施例中,可通过判断电荷变化量A Q1与Δ Q2是否大于阔值来确定是否被触摸。 Specifically, in one embodiment of the present invention may be determined by a charge variation amount Δ Q2 A Q1 and determines whether a touched is greater than a width value. 当然,在本发明的其他实施例中,还可设置其他判断方式,例如判断电荷变化量AQ1与A Q2是否小于阔值,如果小于,则判断感应单元被触摸。 Of course, in other embodiments of the present invention, the determination may also be provided other ways, for example, determines the amount of charge variation width is smaller than the value of AQ1 A Q2, it is less than, the determination sensing unit is touched. 同样地,该阔值也需要根据触摸屏的大小和类型,感应单元的尺寸确定。 Similarly, the width value is also needed depending on the size and type of the touch screen, the size of the sensing unit is determined.

[0051] 步骤S404,如果判断该感应单元被触摸,则此时进一步计算相应的感应单元中所述第一电极至所述自电容的第一电阻与所述第二电极至所述自电容的第二电阻之间的比例关系。 [0051] step S404, the determination if the sensing unit is touched, the case further calculates a corresponding first electrode of said sensing means to said first resistor from the capacitor to the second electrode of the self-capacitance the ratio between the second resistor. 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. 在本发明的实施例中,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。 In an embodiment of the present invention, the ratio between the first resistor and the second resistor in accordance with the self-capacitance of the charge / discharge, a first detection value obtained from the first electrode and / or the second electrode and obtain a second proportional relationship between the detected value calculation. 同上,C1所在的感应单元上的坐标即为Δ Q2/( Δ Q1+ Δ Q2)。 Above, coordinates on the sensing unit where C1 is the Δ Q2 / (Δ Q1 + Δ Q2).

[0052] 在本发明的实施例中,如果感应单元为口形感应单元或L形感应单元,则通过第一电阻和第二电阻之间的比值就可确定在触摸屏上的触摸位置,W下将结合具体的例子进行详述。 [0052] In an embodiment of the present invention, it can determine the touch location on the touch screen if the sensing unit is L-shaped lip or the sensing unit sensing means, the ratio between the first and second resistors through, under the W with reference to specific examples described in detail. 但在本发明的其他实施例中,如果感应单元为矩形感应单元或蛇形(但整体上看相当于矩形)感应单元,则步骤S404只能计算出在触摸屏第一方向上的触摸位置,该第一方向可W是感应单元的长度方向(例如触摸屏的水平方向)。 However, in other embodiments of the present invention, if the sensing unit sensing unit or serpentine rectangular (rectangle, but on the whole the equivalent of) the sensing unit, then step S404 is calculated only in a first direction of the touch position of the touch screen, the the first direction is a longitudinal direction W (e.g. a touch screen in the horizontal direction) of the sensing unit.

[0053] 如果感应单元为矩形感应单元或蛇形(但整体上看相当于矩形)感应单元,则还需要根据感应单元的位置确定在第二方向上的触摸位置。 [0053] If the sensing unit sensing unit or serpentine rectangular (rectangle, but on the whole the equivalent of) the sensing unit, it is also necessary to determine the touch position in the second direction according to the position sensing unit. 在本发明的一个实施例中,第一方向为感应单元的长度方向,第二方向为垂直于感应单元的方向,感应单元水平设置或垂直设置。 In one embodiment of the present invention, the first direction is a longitudinal direction of the sensing unit, the direction sensing unit, the sensing unit disposed horizontally or vertically arranged perpendicular to the second direction.

[0054] 具体地,可采用质屯、算法计算触摸点在第二方向上的触摸位置,W下对质屯、算法进行简单介绍。 [0054] In particular, the quality can be Tun, the touch position of the touch point algorithm in the second direction, the confrontation Tun W, brief algorithm.

[0055] 在滑条和触摸板应用中,经常有必要在具体感应单元的本质间距W上确定出手指(或其他电容性物体)的位置。 [0055] In the slider and a touch panel applications it is often necessary to determine the position of the finger (or other capacitive object) on the nature of the pitch W of the specific sensing unit. 手指在滑条或触摸板上的接触面板通常大于任何个感应单元。 Finger on the touch panel or a touchpad slider is often larger than any induction units. 为了采用一个中屯、来计算触摸后的位置,对运个阵列进行扫描w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单元信号的要求是要大于预设触摸阔值。 In order to employ a village, a touch position is calculated, op array scanning w verify that a given sensor location is effective, the requirements for the adjacent signal sensing unit is greater than a number of preset touch value width . 在找到最为强烈的信号后,此信号和那些大于触摸阔值的临近信号均用于计算中屯、: After finding the strongest signal, this signal and those near the touch signal is greater than the width value are used in the calculation Tun,:

[0089] 在本发明的一个实施例中,相邻两个感应单元200之间的间距相等,运样就可W通过多个感应单元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,提高计算速度。 [0089] In one embodiment of the present invention, the equal spacing between two adjacent sensing unit 200, the sample can be transported by a 110 W and the second side edge 120 evenly divided sensing units 200 of the touchscreen , thereby increasing the operation speed, speed up calculations.

[0090] 当然在本发明的另一个实施例中,相邻两个感应单元200之间的间距也可W不等, 如图9b所示,例如由于用户往往触摸触摸屏的中屯、部位,因此可W将触摸屏中屯、部位的感应单元之间的间距减小,从而提高中屯、部位的检测精度。 [0090] Of course, in another embodiment of the present invention, the spacing between two adjacent sensing unit 200 may be unequal W, as shown in FIG. 9b, for example because the user often touches Tun, touch screen portion, thus W may be a touch screen spacing between the village, a sensing unit portion is reduced, thereby improving the detection accuracy of the village, site.

[0092] 如图10所示,为本发明实施例的感应单元被触摸时的示意图。 [0092] As shown in FIG. 10, a schematic view of the touch sensing unit according to the embodiment of the invention is. 从图10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220,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,感应单元第六部分280的长度为5个单位长度, 感应单元第屯部分290的长度为5个单位长度。 Seen from FIG. 10, a first electrode 210, second electrode 220, the touch position close to the second electrode 220, assuming the length of the sensing unit 10 per unit length, and the sensing unit 10 is uniformly divided into parts, wherein the length of the sixth portion 280 of the sensing unit 5 is a unit length, length of the sensing unit 290 Tun five unit lengths. 经过检测,获知第一电阻和第二电阻之比为9 :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90%。 After testing, the known ratio of the first and second resistors of 9: 1, i.e., the length of the first electrode 210 to a touch position (embodied by a first resistor) is 90% 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9个单位长度的位置,获知,触摸点位于距离第二电极220处1个单位长度的位置。 In other words, the touch point located at a distance of 2,109 units of length of the first electrode, known, position of the touch point located at a distance of 220 units of length of the second electrode.

[0094] 在本发明的一个实施例中,多个感应单元200位于同一层,因此只需要一层IT0即可,从而在保证精度的同时,极大地降低制造成本。 [0094] In one embodiment of the present invention, the plurality of sensing units 200 at the same level, it is only necessary to IT0 layer, thereby sacrificing accuracy, significantly reduce the manufacturing cost.

[0095] 本发明实施例的触摸屏检测装置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忍片的对应管脚相连,在进行触摸检测时通过感应单元自身即可实现对触摸点的定位。 [0095] The touch panel detector of the embodiment of the present invention uses the double end detection sensor unit, i.e. the unit has induced across the electrodes, and each electrode is connected to corresponding pins of the chip tolerance touch screen control, the touch detection is performed when positioning itself can be realized by the sensing unit of the touch point.

[0096] 更为重要的是,本发明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Ξ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,从而提高了测量精度,改善了线性度。 [0096] More importantly, the present invention determines the touch position is achieved by calculating the ratio between the first and second resistors, and therefore with respect to the current design of diamond or angular Ξ, since in determining the touch position, 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.

[0097] 综上所述,本发明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,则会该感应单元会形成自电容,因此本发明通过施加的电平信号可对该自电容进行充电,并根据第一电阻和第二电阻之间的比例关系确定在第一方向上的触摸位置。 [0097] In summary, embodiments of the present invention by applying a level signal induced across the electrodes of the unit, if the sensing unit is touched, the sensing unit will be formed from the capacitance, thus the present invention is applied by the level signal from the capacitor can be charged, and determining a touch position in the first direction based on the proportional relationship between the first and second resistors. 例如在本发明的一个实施例中,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/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。 In one example embodiment of the present invention, the ratio between the first and second resistors in accordance with the self-capacitance when charging / discharging, is detected from the first electrode and / or the second electrode obtained a first proportional relationship between the detected value and the second detection value is calculated. 因此从第一电极和/或第二电极检测该自电容充电/放电时产生的第一检测值和第二检测值。 Thus from the first electrode and / or self-generated when the capacitor charging / discharging of the second electrode and the first detection value of the second detection value. 运样,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,从而进一步确定触摸点在触摸屏的位置。 The sample transport by the first detection value and the second value can be detected at a position of the touch point reaction sensing unit, thereby further determining a position of a touch point in the touch screen.
