技术领域 FIELD

[0002]本发明涉及一种侦测触碰位置的方法与装置,特别是涉及一种在大尺寸表面声波面板侦测触碰位置的方法与装置。 [0002] The present invention relates to a method and apparatus for detecting a touch position, and more particularly to a method and apparatus to detect large-sized surface acoustic wave touch panel in position.

背景技术 Background technique

[0003]表面声波(SAW)式触控面板是一种以在一目的地处感测一表面声波信号的方式以得知在一触控荧幕上的一触控输入的所在位置的触控面板,其是利用一包含一压电材料的换能器将一电能信号转换成该表面声波信号、再感测该表面声波信号在该触控荧幕上行进时是否被该触控输入所阻挡而不能被接收的方式为之。 [0003] Surface acoustic wave (SAW) touch panel is a kind of a destination in the manner sensed at a surface acoustic wave signal in the known location of the touch input on a touch screen of a touch the panel, which is to use a transducer comprising a piezoelectric material converts electrical power signal into a signal of the surface acoustic wave, whether the touch input is blocked again when the sensing signal of the surface acoustic wave travels on the touch screen It can be received without whom the way.

[0004]图1A所示是一种现有的表面声波式触控面板的结构示意。 [0004] Figure 1A is a structure of a conventional surface acoustic wave touch panel schematically. 如图1A所示,该触控面板10具有一荧幕区11及一反射区12,该反射区12中具有一感测装置13,该感测装置13具有一第一及第二横轴换能元件14a及14b与一第一及第二纵轴换能元件15a及15b,其中第二横轴及纵轴换能元件14b及15b分别用以接收与第一横轴及纵轴换能元件14a及15a发出的输入电能信号Signal_Eil及Singal_Ei2对应的表面声波信号Signal_Vl及Signal_V2。 As shown in FIG. 1A, the touch screen panel 10 has a reflective region 11 and a region 12, the reflective region 12 has a sensing device 13, the sensing means 13 having a first and a second transverse axis transducer elements 14a and 14b can with a longitudinal axis of the first and second transducer elements 15a and 15b, wherein the second transverse axis and the longitudinal axis of the transducer elements 14b and 15b, respectively, for receiving the first transverse axis and the longitudinal axis of the transducer element and an input power signal 14a sent Signal_Eil 15a and the surface acoustic wave corresponding to the signal Signal_Vl Singal_Ei2 and Signal_V2. 此外,感测装置13还包含一组第一及第二纵轴反射单元16a及16b与一组第一及第二横轴反射单元17a及17b,且该四组反射单元16a、16b、17a及17b皆包含多个反射器R,且该些反射器R皆为部分透射部分反射。 Furthermore, the sensing means 13 also includes a set of the first and second longitudinal sections 16a and 16b and reflecting a set of first and second transverse axis reflecting means 17a and 17b, and the four reflecting means 16a, 16b, 17a and 17b comprises a plurality of reflectors are R, and R are all the plurality of reflectors partially transmissive reflecting portion. 此时,感测各横轴与纵轴上的可能触点P输入所需的表面声波Signal_V2及Signal_Vl便可由该些反射器R藉由部分反射及部分透射作用加以提供,而该些反射器R—般为印刷在触控荧幕的一玻璃基板上的线层,故其制作成本低。 At this time, the sensing may be required to input contacts P on the vertical axis and the horizontal axis of each surface acoustic wave Signal_V2 Signal_Vl can by partially reflective and partially transmissive by the action of the plurality of reflectors to be provided R, and the plurality of reflectors R - generally printed on a glass substrate of the touch screen line layer, so that its production cost is low. 此外,该些组反射单元16a、16b、17a及17b的反射器R皆为由疏至密排列(由表面声波Signa 1_VI及Signal_V2的行进方向观看),其原因为表面声波Signal_Vl及Signal_V2在未加疏密设计的单一组反射单元16a、16b、17a及17b上会因部分反射作用而使其较后方的反射器R所能反射的表面声波318肪1_¥1及318的1_¥2较少,这样便会影响对该些组反射单元163、1613、17&及17b较后半部对应的输入触点位置的感测能力,故该些组反射单元16a、16b、17a及17b被加以疏密设置以达到对输入至各反射器R的表面声波Signal_Vl及Signal_V2加以平均的补偿作用。 In addition, the plurality of set of reflector units 16a, 16b, 17a and 17b of the reflector R are both from sparse to dense arrangement (viewed by a surface acoustic wave traveling direction and Signa 1_VI Signal_V2), which is the reason the surface acoustic wave is not added Signal_Vl and Signal_V2 single density design reflecting unit group 16a, 16b, 17a and 17b due to the partial reflection that makes it more rearward reflector R can be reflected by the surface acoustic wave fatty 1_ ¥ 1 318 and less 1_ ¥ 2 318, and this will affect the later half of the corresponding input contact location sensing capability of these groups and the reflection unit 163,1613,17 & 17b, so that the plurality of set of reflector units 16a, 16b, 17a and 17b are disposed to be compressional averaged in order to achieve the compensation input to the surface acoustic wave Signal_Vl the reflectors R and Signal_V2. 图1B、图1C及图1D所示分别是图1A所示的表面声波式触控面板在无触点P输入时及在有触点P输入时输出电能信号Signal_Eol及Singal_Eo2的电位图,其中Vy为输出电能信号Signal_Eol的电位图,并为输入触点P的X轴的座标,Vx则为输出电能信号Singal_Eo2的电位图,并为输入触点P的Y轴的座标,其中Vx的波形时间较Vy的波形时间长的原因在于第二表面声波Signal_V2所经过的路径较长所致,而图1D的凹陷部分即为触点P输入被感测得的代表,其被作为判定该触点P输入的位置的依据。 FIGS. 1B, 1C and 1D are a surface acoustic wave touch panel of FIG. 1A and FIG Signal_Eol output power signal and the potential Singal_Eo2 FIG contacts P when there is no input at the input contacts P, in which Vy FIG output potential of the power signal Signal_Eol and input to the X-axis coordinate of the contact point P, compared with the output power signal Vx Singal_Eo2 FIG potential, and the input contacts P of the Y-axis coordinates, wherein the waveform of Vx the reason for a long time than the time that the waveform of Vy Signal_V2 second surface acoustic wave caused by a long path through, while some contacts P is the sensed input is represented in Figure 1D is obtained a recess, which is determined as the contact P based on the input position. 此外,Vy及Vx在起始处可能有一尖波(未显于图示),其为输入电能信号Signal_Eil及Singal_Ei2在刚输入时即分别直接通过第二横轴反射单元组17b及第二纵轴反射单元组16b而为第二横轴换能元件14b及第二纵轴换能元件15b接收所致。 Further, Vy and Vx at the start may have a spike (not shown in), which is the input signal power and Singal_Ei2 Signal_Eil i.e. when just entered directly through the second transverse axis reflecting means 17b and a second group of longitudinal reflecting unit group 16b and the second horizontal axis transducer element 14b and the second longitudinal axis receiving transducer element 15b caused.

[0005]然而,在大尺寸的表面声波式触控面板中,表面声波随着传递距离与经过的反射器数量的增加而减弱,连带地,前述凹陷部分的凹陷幅度也随着减小。 [0005] However, in the large-sized surface acoustic wave touch panel, a surface acoustic wave as the transmission distance increases with the number of the reflectors through the weakened, jointly, the magnitude of the concave recess portion also decreases. 因此,在距横轴与纵轴换能元件14a及15a较远处的触碰有可能因为凹陷的幅度没有超过门槛限值,而无法被侦测到。 Thus, the horizontal axis away from the longitudinal axis of the transducer elements 14a and 15a far more likely to touch the recess because of the amplitude does not exceed the threshold value, and can not be detected.

[0006]由此可见,上述现有技术显然存在有不便与缺陷,而极待加以进一步改进。 [0006] Thus, the above-described prior art problems and disadvantages there is clearly, and to be extremely further improvement. 为了解决上述存在的问题,相关厂商莫不费尽心思来谋求解决之道,但长久以来一直未见适用的设计被发展完成,而一般产品及方法又没有适切的结构及方法能够解决上述问题,此显然是相关业者急欲解决的问题。 In order to solve the above problems, the firms did not dare to think hard and to seek a solution, but has long been seen to be applicable to the design of the development is complete, and general product and the method nor the relevance of the structures and methods can solve the above problems, this is obviously related businesses eager to solve the problem. 因此如何能创设一种新的位置侦测的方法与装置,实属当前重要研发课题之一,亦成为当前业界极需改进的目标。 So how can we create a new method and apparatus for detecting the position, it is currently one of the important research and development issues, it has become the current industry in dire need of improvement goals.

[0067]请参阅图3所示,在本发明的一范例中,是在表面声波面板上分别相应于纵轴与横轴规划多段侦测区域,每一段侦测区域相应于接收到的不同段表面声波。 [0067] Please refer to FIG. 3, in one example of the present invention, respectively corresponding to the detection area and the longitudinal axis of abscissa multistage plan, each segment detection area corresponding to the received surface acoustic waves on the different sections of the panel surface acoustic wave. 前述多段表面声波包括初始传递方向沿表面声波式触控面板纵轴向的多段表面声波与沿表面声波式触控面板横轴向的多段表面声波。 The multi-stage surface acoustic wave propagation direction includes an initial surface acoustic wave touch panel along a longitudinal axis of the multi-stage multi-stage surface acoustic wave along the surface of the surface acoustic wave touch panel of the acoustic wave to the horizontal axis. 例如,以纵轴传递表面声波为例,在表面声波面板的纵轴方向上规划三段侦测区域Pl,P2与P3,并且传递三段表面声波,相应于这三段表面声波,分别接收到表面声波W1,W2与W3,从而产生输出电能信号Swl,Sw2与Sw3。 For example, the surface acoustic wave is transmitted to the longitudinal axis, for example, planning in the longitudinal direction of the three sections of the surface acoustic wave panel detection area Pl, P2 and P3, and three sections of the surface acoustic wave is transmitted, corresponding to the three sections of the surface acoustic wave which respectively receive the a surface acoustic wave W1, W2 and W3, to produce an output power signal Swl, Sw2 and Sw3. 其中,依据相应于接收到的表面声波Wl的相应侦测区域Pl的部分产生部分输出电能信号SI;依据相应于接收到的表面声波W2的相应侦测区域P2的部分产生部分输出电能信号S2;依据相应于接收到的表面声波W3的相应侦测区域P3的部分产生部分输出电能信号S3;并且集合部分输出电能信号SI,S2与S3构成完成完整输出电能信号Smix。 Wherein the power generating section output signal SI based on the respective detection area portion corresponding to the surface acoustic wave Wl Pl is received; generating section based on the output power signal S2 corresponding to the portion of the surface acoustic wave corresponding to the received detection area W2 and P2; based on the corresponding detection area corresponding to the surface acoustic wave W3 and P3 of the received portion of the output power signal generating portion S3; and part of the output power signal set SI, S2 and S3 constitute complete full output power signal Smix. 前述说明虽然是以纵轴为例,本技术领域具有通常知识的技术人员可推知前述说明也适用于横轴。 Although the foregoing description is a vertical axis, for example, in the art having ordinary knowledge in the art can infer the foregoing description also applies to the horizontal axis. 此外,输出电能信号Smix包括但不限于部分输出电能信号SI,S2与S3,也可以包括相应侦测区域Pl之前的输出电能信号以及相应侦测区域P3以后的输出电能信号。 Further, the output power signal Smix including but not limited portion of the output power signal SI, S2 and S3, the power may also include an output signal before the respective detection areas and the corresponding detection area Pl P3 after the output power signal.

[0068]虽然在图3中是以三段部分输出电能信号为例,在本技术领域具有通常知识的技术人员可以推知,前述的部分输出电能信号、传递的表面声波可以是不同段数,本发明并不加以限制。 [0068] Although an example in is part of the output power signals of the three sections in FIG. 3, in the art having ordinary knowledge in the technical field can be inferred, the surface acoustic wave the part of the output power signal, transmitted may be a different number of segments, the present invention not be limited. 此外,前述每一段部分输出电能信号的撷取可以是依据相应于不同侦测区域的时间区间来撷取,其中该时间区间可以是参考接收该段表面声波的启始时间或提供该段表面声波的起始时间,也就是距接收该段表面声波的启始时间或提供该段表面声波的起始时间的一段时间,每一段表面声波的该段时间不必然相同。 In addition, each piece of the capture portion of the output power signal may be based on a different time interval corresponding to the detection area to capture, wherein the time interval may start receiving the time reference segment providing the surface acoustic wave or surface acoustic wave segment start time, i.e. the time from the start of the segment receiving surface acoustic waves or provide a time period start time of the surface acoustic waves, each section of the surface acoustic wave is not necessarily the same period of time.

[0069]在本发明的一范例中,是分别将接收到的表面声波Wl,W2与W3转换成输出电能信号Swl,Sw2与Sw3后,再分别由输出电能信号Swl,Sw2与Sw3中撷取部分输出电能信号SI,S2与S3,以构成完整输出电能信号Smix。 [0069] In an example of the present invention, after respectively converting the received surface acoustic wave Wl, W2 and W3 into an output power signal Swl, Sw2 and Sw3, are then retrieved from the output power signal Swl, Sw2 and Sw3 in power signal portion of the output SI, S2 and S3, to construct a complete output power signal Smix.

[0070]在本发明的另一范例中,是在接收的过程中,分别将接收到的表面声波Wl,W2与W3中相应于侦测区域Pl,P2与P3的部分转换成部分输出电能信号SI,S2与S3。 [0070] In another example of the present invention, in the process of receiving, respectively, the received Wl of the surface acoustic wave, the portion corresponding to the detection area Pl, P2 and P3 into an output power signal portion W2 and W3, SI, S2 and S3.

[0071]此外,本发明还包括利用增加表面声波的波数,或将接收到的表面声波转换的输出电能信号提高增益,将输出电能信号放大,使得被撷取的部分输出电能信号SI,S2与S3维持在一预设范围。 [0071] Further, the present invention further comprises the use of increasing the wave number of the surface acoustic wave, or the received surface acoustic waves converted output power signal to increase the gain, the output power of the signal amplification, such that part of the output power signal SI is captured, S2 and S3 is maintained at a pre-set range.

[0072]在本发明的一范例中,是以增加表面声波的波数来提高输出电能信号。 [0072] In an example of the present invention, the surface acoustic wave number is increased to increase the output power signal. 每一段传递的表面声波的波数可以是不同的。 Surface acoustic wave number of each piece of transmission may be different. 例如,第三段的表面声波波数大于第二段的表面声波波数,并且第二段的表面声波波数大于第一段的表面声波波数。 For example, the number of surface acoustic wave is greater than the second section of the third stage surface acoustic wave number, and the number of surface acoustic wave surface acoustic wave is greater than the second section of the first segment number. 换言之,至少一段在后的表面声波波数大于在前的一段表面声波波数。 In other words, at least some number of surface acoustic wave in the surface acoustic wave is greater than the period of the preceding number. 显然地,前述的完整输出电能信号在表面声波式触控面板未被触碰时可能是部分或全部呈现锯齿波型(sawtooth waveform),呈现锯齿波型的范围至少相应于表面声波式触控面板能侦测到的触碰的范围,或是相应于前述横轴及纵轴换能元件或反射器将表面声波反射而穿过表面声波式触控面板的范围。 Obviously, the full output power signal when the surface acoustic wave touch panel untouched may be partially or fully exhibit a sawtooth pattern (sawtooth waveform), presenting at least a range corresponding to the sawtooth-type surface acoustic wave touch panel can detect the touch of a range, or the range of the horizontal axis corresponds to the longitudinal axis of the transducer and the reflector element or the surface acoustic waves reflected through the surface acoustic wave touch panel.

[0073]在本发明的另一范例中,是以提供增益来提高输出电能信号。 [0073] In another example of the present invention is to provide an output power signal to increase the gain. 每一段的接收到的表面声波可以是以不同的增益来撷取部分输出电能信号。 Received surface acoustic waves of each section may be a different gain to retrieve part of the output power signal. 换言之,所述每一输出电能信号是由感测装置分别依据一增益产生,相应于在后的至少一段表面声波的该增益大于相应于在前的一段表面声波的该增益,或者是至少一段在后的部分输出电能信号的增益大于在前的一段部分输出电能信号的增益。 In other words, each of said power signal is output by the sensing means are respectively generated according to a gain corresponding to the gain in the at least a section of the surface acoustic wave is greater than the gain of the surface acoustic wave corresponding to the preceding period, or a period of at least gain section output power signal after the gain is greater than some part of the previous output power signal.

[0074]在本发明的再一范例中,是兼用增加波数与增益来提高输出电能信号。 [0074] In another example of the present invention, it is used along with increasing wave number and the output power signal to increase the gain. 无论是以何种方式提高输出电能信号,相应触碰造成的凹陷部分的凹陷幅度也随着被提高。 No matter which embodiment is to enhance the output power signal, the amplitude of the recessed portion depressed along with the corresponding touch caused it is increased.

[0075]藉由前述方式,可以让输出电能信号在表面声波式触控面板没有被触碰时维持在一预设范围内,并且相应触碰造成的凹陷部分的凹陷幅度也随着被提高到可以被侦测到的幅度,例如大于一门槛限值。 [0075] By the way, allowing the output power signal is maintained within a predetermined range of the surface acoustic wave touch panel is not touched, the touch and the corresponding recessed portion recessed amplitude is also caused to be raised as amplitude can be detected, for example greater than a threshold value.

[0076]在本发明的第二实施例中,可以是以传递单段表面声波,并且将接收到的表面声波以多段不同增益转换成多段部分输出电能信号,并且让每一段部分输出电能信号维持在一相近范围。 [0076] In the second embodiment of the present invention, it may be a transferred single-stage surface acoustic wave, and the received surface acoustic wave multistage different gain conversion into multi-part of the output power signal, and so that each segment portion of the output power signal is maintained in a similar range. 但在大尺寸表面声波式触控面板中,较后面的信号可能衰减到难以侦测的范围,因此即使提高增益,可能无法由部分输出电能信号侦测出触碰及触碰位置。 However, in the large size of the surface acoustic wave touch panel, the latter more difficult to detect the signal may be attenuated to a range, even if increasing the gain, and may not detect the touch position from the touch part of the output power signal.

[0077]在本发明的第三实施例中,是在侦测到相应于触碰的凹陷部分跨相邻多段部分输出电能信号时,藉由再传递一段表面声波,并且依据接收到的表面声波产生包含凹陷部分的一段输出电能信号,以精确地判断出触碰位置。 When [0077] In a third embodiment of the present invention, in the recessed portion corresponding to the detected touched multistage cross section adjacent the output power signal, transmitted by another period of the surface acoustic wave, and the surface acoustic wave based on the received generating a power signal output section including a recessed portion to accurately determine the touch location. 例如是依据凹陷部分计算出质心位置。 For example, a recessed portion based on the calculated centroid position.

[0078]综合上述,本发明提供的一种位置侦测方法,请参阅图4所示,是依据本发明的第三实施例的侦测位置的流程示意图。 [0078] In summary, A position detecting method of the present invention provides, see FIG. 4 is a schematic diagram of a process to detect the position of a third embodiment of the present invention. 依据步骤410所示,产生在一表面声波式触控面板未被触碰时的一完整输出电能信号,所述的完整输出电能信号是分别依据多个表面声波的不同部分产生的多段部分输出电能信号集合而成。 According to step 410, a surface acoustic wave is generated in a complete output power signal when the touch panel is untouched, the full output power signal based on multi-part respectively different portions of the plurality of output electrical power generated by the surface acoustic wave the signal gathered together. 之后,如步骤420所示,产生在表面声波式触控面板被触碰时的一完整输出电能信号。 Thereafter, as shown in step 420, it generates an output power signal when in a full surface acoustic wave touch panel is touched. 接下来,如步骤430所示,与未被触碰时的完整输出电能信号相比较,侦测被触碰时的完整输出电能信号的每一个凹陷部分,其中每一个凹陷部分的凹陷程度大于一门槛限值。 Next, as shown in step compared with the output power signal when the complete untouched, each recessed portion of the complete output power signal when the touch is detected, wherein a recessed extent of each recess portion 430 is larger than a threshold limit. 再接下来,如步骤440所示,依据每一个凹陷部分分别侦测出一位置。 Then again, as shown in step 440, the recessed portions are based on each detect a position. 此外,前述步骤410至440可以是由控制电路来达成。 Furthermore, the foregoing steps 410 to 440 may be achieved by the control circuit.

[0079]请参阅图5A并对照图3所示,相应于一触碰的凹陷部分Tl跨过部分输出电能信号SI与S2,如果依此凹陷部分计算触碰的质心位置,在部分输出电能信号S2上的凹陷幅度较大,会造成质心位置偏向部分输出电能信号S2。 [0079] Please refer to FIG. 5A and FIG. 3 shows a control corresponding to a touch portion of the recessed portion across the output power signal Tl SI and S2, and so if the calculated touch the recessed portion of the centroid position, the portion of the output power signal S2 large amplitude at the recess, the centroid position will cause the biased portion of the output power signal S2. 因此,如图5B所示,在判断出凹陷部分Tl的凹陷幅度大于门槛限值th时,相应于凹陷部分Tl的范围提供一相应波数的表面声波在表面声波式触控面板上传递,以产生包括相应于同触碰的凹陷部分T2的部分输出电能信号Sr。 Thus, as shown, to provide a surface acoustic wave in the corresponding wavenumber range 5B recessed portion recessed amplitude limit Tl is greater than the threshold th, corresponding to the recessed portion of Tl is judged on the transmission surface acoustic wave touch panel, to generate comprising a portion corresponding to an output power signal with the touch of a recess portion T2 Sr. 由于是依据同段表面声波产生的输出电能信号,因此判断出的质心位置能较精准地呈现出触碰位置。 Since the output power signal is generated by surface acoustic wave with the segment, it is determined that the centroid position can be more accurately showing the touch position.

[0080]换言之,前述步骤410至步骤430是可以视为进行一第一阶段侦测,并且在侦测到任一凹陷部分跨多段部分输出电能信号时,进行一第二阶段侦测,以侦测出跨多段部分输出电能信号所代表的位置。 When [0080] In other words, the step 410 to step 430 can be considered a first phase detector, and detecting either a recessed portion across multiple pieces of partial power output signal, a second phase detector to detect measured across multiple pieces of partial power output signal representative of the position.

[0081]第二阶段侦测是依据每一个跨多段部分输出电能信号的第一阶段凹陷部分产生一段第二阶段表面声波,并且依据接收到的表面声波产生一第二阶段输出电能信号,第二阶段输出电能信号为非锯齿波。 [0081] The second stage is to produce the detection period based on the second stage of the first stage surface acoustic wave across each of the pieces of partial output power signal recessed portion, and generates an output power signal based on the second stage of the surface acoustic wave is received, a second sawtooth signal is not output power stage. 假设步骤430中侦测到的凹陷部分为第一阶段凹陷部分,每一个第二阶段输出电能信号分别相应于一个跨多段部分输出电能信号的第一阶段凹陷部分,并且在相应的第一阶段凹陷部分会呈现一第二阶段凹陷部分。 Step 430 is assumed to detect the recessed portion of the first stage recess portion, each of the second output stage of a power signal corresponding to each phase of a multi-section across the first output power signal recessed portion, and a respective recess in the first stage The second part will present a stage recessed portion. 前述的位置是依据第二阶段凹陷部分来侦测。 The second stage is based on the position of the recessed portion to detect. 亦即,依据第二阶段输出电能信号中相应于前述第一阶段凹陷部分的部分侦测出前述的位置。 That is, according to the second phase of the output power signal portion corresponding to the recessed portion of the first stage of the detect position.
