具体实施方式 Detailed ways

[0045] 图1为本发明一实施例的电子触控装置处于第一感测模式的方块示意图,图2为本发明一实施例的电子触控装置处于第二感测模式的方块示意图。 FIG 2 is an electronic block diagram of the touch device in the second embodiment of the sensing mode embodiment of the invention a block diagram of an embodiment of an electronic device in a first touch sensing mode diagram of an embodiment [0045] FIG. 1 of the present invention. 请先参照图1,本实施例的电子触控装置100包括触控接口110、至少一感测单元120、切换单元130以及处理单元140,其中触控接口例如是一般显示器的触控面板或其他具触控感测功能的触摸板。 Please refer to FIG. 1, an electronic touch device 100 according to the present embodiment includes a touch interface 110, at least a sensing unit 120, the switching unit 130 and a processing unit 140, wherein the touch display interfaces, for example, a general touch panel, or other touchpad with touch sensing function. 除此之夕卜,在本实施例中,电子触控装置100还包括驱动单元160。 In addition Eve BU, in the present embodiment, the electronic touch device 100 further includes a drive unit 160. 驱动单元160稱接于切换单元130与处理单元140,且适于传送驱动信号,而驱动单元160例如是依据控制信号SC2决定驱动信号的传送与否。 It said driving unit 160 connected to the switching unit 130 and processing unit 140, and adapted to transmit a driving signal, and the driving unit 160 is determined, for example, whether or not the drive transmission signal according to the control signal SC2.

[0046] 另外,处理单元140例如内嵌于承载单元150中,且承载单元150例如为电脑系统或任何具有处理单元的电子产品。 [0046] Further, the processing unit 140, for example, embedded in the carrier unit 150, and the carrying unit 150 is, for example, or any computer system having electronic processing unit. 此外,本实施例的处理单元140也分别与感测单元120以及切换单元130耦接。 Further, the processing unit 140 of the present embodiment respectively with the sensing unit 120 and the switching unit 130 is coupled to ground. 其中,本实施例的感测单元120虽分别示出在图1的不同处,但感测单元120a与感测单元120b实际上均为感测单元120的一部分。 Wherein, the part of the sensing unit 120 of the embodiment, although differences are shown in FIG. 1, the sensing unit sensing unit 120a and 120b are actually sensing unit 120 of the present embodiment.

[0047] 如图1所示,切换单元130是依据控制信号SCl将电子触控装置100的触控感测系统180切换为第一感测模式或第二感测模式,而控制信号SCl例如是由处理单元140输出,且例如是依据外部指令所产生或是依据承载单元150的功能需求自动产生。 [0047] As shown, the switching unit 130 according to the control signal SCl is the touch-sensing system 180 of the electronic touch device 100 is switched to a first mode or a second sensing sensing mode, the control signal SCl. 1, for example, output by the processing unit 140, and for example, or generated based on the functional requirements of the carrying unit 150 according to an external command is automatically generated. 另一方面,切换单元130例如包括微处理器、开关装置以及逻辑运算单元的至少其中之一。 On the other hand, the switching unit 130 includes, for example a microprocessor, a switching means and a logic operation unit to at least one of them.

[0048] 在图1中,本实施例的电子触控装置100是被切换为第一感测模式,其中,本实施例的第一感测模式例如为自电容感测模式。 [0048] In Figure 1, an electronic touch device 100 according to the present embodiment is switched to a first sensing mode, wherein a first sensing mode of the present embodiment, for example, self-capacitance sensing mode. 而自电容感测模式是利用单一感测线上的容值变化取得单点的触控信息。 Self-capacitance sensing mode is to obtain a single point by a single change in capacitance of the sense lines touch information. 如图1所示,在自电容感测模式的情况下,感测单元120b通过切换单元130的切换以与触控接口110彼此耦接。 As shown, in the case where the self-capacitance sensing mode, the sensing unit 120b by the switching unit 130 is switched to the touch interface 110 coupled to each other. 详细来说,触控接口的第二线路114透过切换单元130而与感测单元120b的感测线122彼此耦接。 In detail, the second line interface 114 via the touch switching unit 130 is coupled to the sense line 120b, the sensing unit 122 with each other. 如此一来,感测单元120b便能通过第二线路114与感测线122感测到触控接口110上的信号。 Thus, the sensing unit 120b will be able to line 114 through a second sensing line 122 and the sensing signal is sensed on the touch interface 110.

[0049] 请继续参照图1,触控接口110包括复数条第一线路112与复数条第二线路114,其中第一线路112与第二线路114构成复数个感测点SP。 [0049] Please continue to refer to FIG. 1, the touch interface 110 includes a plurality of first line 112 and the second plurality of line 114, of which a first line 112 and second line 114 constituting a plurality of sensing point SP. 当一触控物体170 (例如手指)接近触控接口110位于位置Pl的感测点SP时,感测单元120a会侦测到感测信号SI,而感测信号SI例如是对应位置Pl的第一线路112与固定电极(如接地的电极)的变化电容值或是可侦测的电压或电流值。 When a touch object 170 (e.g., a finger) near the interface 110, the touch sensing point SP is located at the position Pl, the sensing unit 120a detects a sensing signal SI, SI sensed signal corresponding to the first position Pl, for example, the a line 112 with the stationary electrode (e.g. ground electrode), or a change in the capacitance value of the voltage or current value is detectable. 除此之外,由于此时切换单元130将感测单元120b与第二线路114耦接在一起,所以感测单元120a也会侦测到另一感测信号S2,其中,感测信号S2例如是对应位置Pl的第二线路114与固定电极(如接地的电极)的变化电容值。 In addition, since the switching unit 130 and the second sensing unit 120b line 114 are coupled together, the sensing unit 120a will detect a sensing signal S2 to the other, wherein the sensing signal S2 e.g. is the change in capacitance line 114 and the second fixed electrode (e.g. ground electrode) corresponding to a position Pl.

[0050] 接着,感测单元120再将感测信号SI与S2传送至处理单元140,进而使处理单元140依据感测信号SI与S2决定触控物体170相对于触控接口110的位置座标。 [0050] Next, the sensing unit 120 and then the sensing signal SI and S2 to the processing unit 140, thereby enabling the processing unit 140 according to the sensing signal SI and S2 determines position coordinates of the touch object 170 with respect to the touch interface 110 . 从另一个角度观看,第二线路114与第一线路112例如是对应笛卡尔(Cartesian)座标系统中的X_Y座标轴。 From another point of view, the first line 114 and second line 112, for example, correspond to the Cartesian coordinate axes X_Y (of Cartesian) coordinate system. 而通过感测信号SI与S2,处理单元140便可决定触控物体170相对于触控接口110的座标(x,y)。 And by sensing signals SI and S2, the processing unit 140 can decide the touch object 170 with respect to the touch interface 110 coordinates (x, y). 然而,本发明并不受限于此,在另一实施例中,本发明也可利用极座标系统来表示触控物体170相对于触控接口110的位置。 However, the present invention is not limited thereto. In another embodiment, the present invention may also be represented in polar coordinate system of the touch position of the touch object 170 with respect to the interface 110.

[0051] 整体来说,在无触控物体触碰或接近触控接口110时,感测点SP所对应的第一线路112与第二线路114会有两个电容基底值(base line value),而当触控物体170经由触控或接近触控接口110时,对应的感测点SP会因被触控而使第一线路112与第二线路114原本的电容值产生正向变化量。 [0051] Overall, no touch object when the touch or proximity touch interface 110, a first sensing point SP line corresponding to two capacitors 112 and 114 have a base value of the second line (base line value) and when the touch object 170 via a touch or near touch interface 110, a corresponding sensing point SP is the first line 112 and the capacitance value of the original 114 to generate the second line is touched by a positive variation. 接着,感测单元120能感测到感测第一线路112与第二线路114个别产生的电容增加量(例如发生变化的感测信号SI与S2),进而使处理单元140决定触控物体170相对于触控接口110的触控位置。 Next, the sensing unit 120 can sense the increased amount of capacitance to the sensing line 114 and the second individual to generate a first line 112 (e.g., sensing a change in signal SI and S2), the processing unit 140 further determines that the touch object 170 with respect to the touch position of the touch interface 110.

[0052] 依据上述,在第一感测模式的情况下,本实施例的处理单元140是通过感测单元120所感测到的感测信号SI与S2来决定触控位置。 [0052] According to the above, in a case where a first sensing mode, the processing unit 140 of the present embodiment is determined by the position of the touch sensing unit 120 sensed the sense signal SI and S2 sense. 也就是说,在本实施例中,触控接口110上的第一线路112与第二线路114类似于自电容型触控接口上沿不同方向延伸的感测线。 That is, in the present embodiment, the first line 112 and second line 114 is similar to the sense lines extending in different directions from the capacitive touch on the touch interface 110 interfaces embodiment. 由于此时的触控感测系统180为自电容感测模式,所以电子触控装置100便具有省电以及信号分析简单的优点。 At this time, since the touch sensing system 180 is a self-capacitance sensing mode, the electronic touch device 100 has a power and signal analysis will be simplified. 除此之外,在其他实施例中,为便于电路的布局,感测单元120也可以是分别耦接于触控接口110与切换单元130的两独立感测单元。 In addition, in other embodiments, for ease of layout of the circuit, the sensing unit 120 may be respectively coupled to the touch interface 110 and the switch unit two individual sensing unit 130.

[0053] 图2为图1的电子触控装置100处于第二感测模式的方块示意图。 [0053] Figure 2 is an electronic touch device 100 of FIG. 1 a block diagram of a second sensing mode in. 举例而言,当使用者想从单点触控模式转换成多点触控模式以执行更多功能(例如视窗的放大或缩小)时,处理单元140会输出控制信号SCl以将电子触控装置100的触控感测系统180切换为第二感测模式,其中触控信号SCl例如是依据外部指令或触控接口110上的触控信息上所产生,其例如为感测信号SI与S2的至少其中之一。 For example, when the user want to convert from a single-touch mode to the multi-touch mode to perform additional functions (e.g., enlarged or reduced window), 140 outputs a control signal to an electronic processing unit touch device SCl the touch sensing system 180 is switched to the second sensing mode in which the touch signal is generated, for example, SCl touch information based on the external command or a touch interface 110, for example, to sense signals SI and S2 100 at least one of them.

[0054] 举例而言,当处理单元140通过感测信号SI或S2感测到目前触控接口110上有多个感测点SP被触控时,便可自动输出控制信号SCl以控制切换单元130的切换,进而使触控感测系统180切换到例如是具有多点触控功能的第二感测模式。 [0054] For example, when the processing unit 140 by sensing a sensed signal SI or S2 to a plurality of current sensing point SP is touched on the touch interface 110 may automatically outputs a control signal to control the switching unit SCl switch 130, thereby enabling the touch-sensing system 180 is switched to, for example, multi-touch sensing function in a second mode. 在本实施例中,第二感测模式例如为互电容感测模式,其通过侦测感测点的感测波形以取得驱动线与感测线间的电容容值,并利用所侦测的容值变化来取得单点或两点以上的触控信息。 In the present embodiment, the second sensing mode, for example, a mutual capacitance sensing mode, which is to obtain the value of the capacitor between the driving lines and the sensing lines detected by sensing the waveform of the sensing points, and using the detection of capacitance variation to obtain a single point or at two or more touch information.

[0055] 如图2所示,当电子触控装置100处于互电容感测模式时,触控接口100的第二线路114透过切换单元130与驱动单元的驱动线162彼此耦接。 [0055] As shown in FIG 2, when the electronic device 100 is the touch mutual capacitance sensing mode, the touch interface of the second link 114 through 100 of the switching unit 130 and the line driving unit 162 coupled to each other. 另一方面,处理单元140例如会输出控制信号SC2至驱动单元160,以使驱动单元160输出驱动信号SD至触控接口110。 On the other hand, for example, the processing unit 140 outputs a control signal SC2 to the driving unit 160, so that the driving unit 160 outputs a drive signal SD to the touch interface 110. 如此一来,驱动单元160便能通过驱动线162与第二线路114将驱动信号SD传送到触控接Π 110。 Thus, by driving the driving unit 160 will be able to line 162 and line 114 to a second drive signal SD is transmitted to the touch contact Π 110.

[0056] 详细来说,在操作期间,处理单元140在不同时间依序向每一条驱动线162输出驱动信号SD。 [0056] In detail, during operation, the processing unit 140 sequentially driving each SD 162 outputs a drive signal to the line at different times. 接着,驱动信号SD通过驱动线162、切换单元130与第二线路114被传送至触控接口110。 Next, the drive signal SD by the driving line 162, the switching unit 130 and the second line 114 is transmitted to the touch interface 110. 由于第一线路112与第二线路114的交界处(即感测点SP)会形成电容耦合节点,所以第二线路114上的电荷会透过感测点SP附近的电容(未示出)耦合至交叉对应的第一线路112。 Since the first line 112 and second line 114 at the junction (i.e., the sensing point SP) will form a capacitive coupling node, so the charge on line 114 will be transmitted through the second sensing point SP near the capacitor (not shown) coupled corresponding to a first intersection line 112. 如此一来,感测单元120a便可透过第一线路112感测出感测信号SI,其中感测信号SI例如是电流、电压或电容值。 Thus, the sensing unit 120a through 112 can be sensed signal SI from the first sensing line, wherein the sensing signal SI for example, current, voltage or capacitance.

[0057] 具体而言,当触控物体170 (例如手指)接近触控接口110位于位置Pl的感测点时,原本耦合至到第一线路112的驱动信号SD会发生变化,而使得感测单元120a在对应位置Pl所侦测到感测信号SI与其他位置有所不同。 [0057] Specifically, when the touch object 170 (e.g., a finger) near the touch interface 110 is located at a position of the sensing point Pl, the original is coupled to the drive signal SD to the first line 112 will change, so that the sense Pl unit 120a at the corresponding position to the detected sense signal SI differ from other locations. 接着,处理单元140便会接收到上述发生变化的感测信号SI,进而决定出触控物体170相对于触控接口110的位置座标。 Next, the processing unit 140 will sense receives the signal SI changes, thereby determining the position coordinates of the touch object 170 with respect to the touch interface 110.

[0058] 类似地,当有两个以上的触控物体接近触控接口110时,感测单元120a会感测到两个发生变化的感测信号SI,而再搭配第二线路114接收驱动信号SD的时间,处理单元140便能辨识出两点以上的触控位置。 [0058] Similarly, when there are more than two touch object approaches the touch interface 110, the sensing unit 120a will be sensed sensing a sensing signal SI two changes, and then with a second signal line 114 receives a driving SD time, the processing unit 140 will be able to identify at least two touch positions. 所以通过如图2所示的互电容感测模式,电子触控装置100能实现多个同时或几乎同时触控事件的辨识。 Therefore, as shown in FIG. 2 by a mutual capacitance sensing mode, the electronic device 100 can realize a touch recognition simultaneously or nearly simultaneously multiple touch events. 换句话说,图2的电子触控装置100的触控感测系统180可侦测多个同时、接近同时或一时间周期内触控接口110上发生的触 In other words, the touch of the touch sensing system of the electronic device 180 of FIG. 2 100 can detect multiple simultaneous, or nearly simultaneous touch occurs on the touch interface 110 within a period of time

控事件。 Control events.

[0059] 整体来说,当使用者想从单点触控模式转换成多点触控模式以执行更多功能时(例如视窗的放大或缩小),本实施例的处理单元140可依据使用者所输入的外部指令或触控接口110的触控信息对切换单元130输出控制信号SCl以将第二线路114与驱动单元160彼此耦接。 [0059] Overall, when the user want to convert from a single-mode multi-touch touch mode to perform additional functions (e.g., enlarged or reduced window), the processing unit 140 of the present embodiment can be based on the user external instruction or a touch input interface 110 on the touch information switching unit 130 outputs a control signal SCl to a second line 114 and the driving unit 160 are coupled to each other. 其中触控信息例如是感测信号S2。 The touch sensing, for example, information signal S2. 举例而言,当感测单元120a感测到复数个发生变化的感测信号S2时,处理单元140会对上述的感测信号S2进行逻辑运算并产生控制信号SCl或是通过感测信号S2的数学组合产生控制信号SCl,以控制切换单元130的切换。 For example, when the sensing unit 120a senses a plurality of sensing when the signal S2 changes, the processing unit 140 have the above-described sensing signal S2 is a logic operation and generates control signals SCl, or by sensing a signal S2 mathematical combination generates control signals SCl, to control the switching unit 130 is switched.

[0060] 或者,在另一实施例中,当承载单元150必须进入需要完整触控信息的情境时,例如开启需要多点触控功能的工作状态,处理单元140会发送控制信号SCl给切换单元130以使触控感测系统180进入互电容感测模式(即本实施例的第二感测模式)。 [0060] Alternatively, in another embodiment, when the carrying unit 150 must enter the information required full touch situation, for example, require multi-touch functionality open operating state, the processing unit 140 sends a control signal to the switching unit SCl 130 so that the touch-sensing system 180 into the mutual capacitance sensing mode (i.e., a second sensing mode of the present embodiment).

[0061] 另一方面,当承载单元150基于省电考量自动进入闲置模式时,承载单元150内部会计时闲置时间且自动发送控制信号SCl至切换单元130,以将触控感测系统180切换至一般认为功能较受限制,但较为省电的自电容型感测模式(即本实施例的第一感测模式)。 [0061] On the other hand, when the idle time power 150 based on the carrier unit automatically enters an idle mode when considerations, the carrier 150 and internal accounting unit automatically transmits a control signal SCl to the switching unit 130 to the touch-sensing system 180 is switched to is generally considered more limited functionality, but more power from the capacitive sensing mode (i.e., a first sensing mode of the present embodiment). 除此之外,在另一实施例中,考量到长期使用的省电效能,处理单元140也可接收由外部发送的指令以强制触控感测系统180使用自容式感测模式。 In addition, in another embodiment, the power saving taking into consideration the effectiveness of long-term use, the processing unit 140 may also receive instructions transmitted by an external force to the touch-sensing system 180 using a self-contained sensing mode.

[0062] 换句话说,本实施例的电子触控装置100的触控感测系统180提供自电容与互电容的两种感测模式,以提供使用者或系统在不同情况下可选择适合的触控感测模式。 [0062] In other words, the touch sensing system of the electronic touch device 100 of this embodiment 180 provides a self-capacitance and mutual capacitance sensing mode two, to provide the user or the system in different situations of suitable selectable touch-sensing mode. 其中切换单元130作为切换自电容与互电容感测模式的开关,且切换单元130的切换例如是依据取得的触控信息或承载单元150的功能需求以选择出最适当的运作模式。 Wherein the switching unit 130 as a switching self-capacitance and the mutual capacitance sensing mode switch, and the switching of the switching unit 130, for example, according to the functional requirements of the touch information acquisition unit 150 or the bearer to select the most appropriate mode of operation. 如此一来,触控感测系统180变兼具了两种感测模式的优点。 Thus, the touch sensing system 180 combines the advantages of both variants sensing mode. 另外,在本实施例中第一感测模式与第二感测模式虽分别为自电容与互电容感测模式,然而在其他实施例中,第一感测模式与第二感测模式也可以分别为互电容与自电容感测模式。 Further, although in the present embodiment, the first sensing patterns and second sensing patterns are self capacitance and mutual capacitance sensing mode, however, in other embodiments, the first sensing patterns and second sensing patterns may be They are self capacitance and mutual capacitance sensing mode.

[0064] 除此之外,在其他实施例中,触控感测方法还包括依据触控接口180的一触控信息产生控制信号SC1,其中上述的触控信息例如为第一感测信号与该第二感测信号的至少其中之一。 [0064] In addition, in other embodiments, the touch sensing method further comprises generating a control signal SC1 touch information based on a touch interfaces 180, wherein said touch information, for example, a first sensing signal and wherein at least one of the second sensing signal. 或者,在另一实施例中,触控感测方法还包括依据一外部指令产生控制信号SCl。 Alternatively, in another embodiment, the touch sensing method further comprises generating a control signal according to an external command SCl. 由于本实施例的触控感测方法可以由图1与图2实施例的叙述中得到足够的教示、建议与实施说明,因此不再赘述。 Since the touch sensing method according to the present embodiment described embodiments may be obtained in sufficient teachings, the embodiment is recommended embodiment described in FIG 1 and FIG 2, and therefore will not be repeated.

[0065] 综上所述,在本发明的实施例中,由于切换单元可依据控制信号将触控感测系统切换为第一感测模式或第二感测模式(例如为自电容感测模式与互电容感测模式),所以触控感测系统能依据目前的状况提供使用者或系统最合适的感测模式。 [0065] As described above, in the embodiment of the present invention, since the switching unit may be switched to the touch-sensing system to sense a first mode or a second mode based on sensing a control signal (e.g., self-capacitance sensing mode and mutual capacitance sensing mode), the touch sensing system can provide the user or the system most suitable sensing mode based on the current situation. 如此一来,本发明的实施例的触控感测系统与电子触控装置便兼具自电容感测模式的省电优点以及互电容感测模式的多点触控功能。 Thus, the touch sensing system of touch with the electronic apparatus of the embodiment of the present invention will be power-saving advantages of both self capacitance sensing mode and the mutual capacitance sensing mode multi-touch functionality.
