背景技术Background technique
请参考图1，图1为先前技术的触控装置100的示意图。触控装置100包含单一个触控面板110以及控制电路120。控制电路120耦接于触控面板110。当触控面板110被触碰时，触控面板110会产生并输出相对的触碰信号至控制电路120。控制电路120再依据所接收到的触碰信号，判断触控面板110被触碰的位置。然而，因为用以生产触控装置的设备的限制，故图1的架构并不适合用在超大尺寸的触控装置上。Please refer to FIG. 1 , which is a schematic diagram of a touch device 100 in the prior art. The touch device 100 includes a single touch panel 110 and a control circuit 120 . The control circuit 120 is coupled to the touch panel 110 . When the touch panel 110 is touched, the touch panel 110 will generate and output a corresponding touch signal to the control circuit 120 . The control circuit 120 then determines the touched position of the touch panel 110 according to the received touch signal. However, due to the limitations of the equipment used to produce the touch device, the architecture of FIG. 1 is not suitable for super-sized touch devices.
请参考图2，图2为先前技术的另一种触控装置200的示意图。触控装置200包含多个触控面板210以及控制电路220。控制电路220耦接于多个触控面板210。多个触控面板210被拼装成触控装置200的触控面。当各触控面板210被触碰时，触控面板210会产生并输出相对的触碰信号至控制电路220。控制电路220再依据所接收到的触碰信号，判断各触控面板210被触碰的位置。然而，以图2为例，多个触控面板210使用了相同的四角坐标(0，0)、(10，0)、(0，10)及(10，10)，故当碰触点落在两个或更多个触控面板210相邻的边界上时，控制电路220很容易将用户单指的触碰误判为多指的触控。Please refer to FIG. 2 , which is a schematic diagram of another touch device 200 in the prior art. The touch device 200 includes a plurality of touch panels 210 and a control circuit 220 . The control circuit 220 is coupled to the plurality of touch panels 210 . A plurality of touch panels 210 are assembled into a touch surface of the touch device 200 . When each touch panel 210 is touched, the touch panel 210 will generate and output a corresponding touch signal to the control circuit 220 . The control circuit 220 then determines the touched position of each touch panel 210 according to the received touch signal. However, taking FIG. 2 as an example, multiple touch panels 210 use the same four-corner coordinates (0, 0), (10, 0), (0, 10) and (10, 10), so when the touch point falls When two or more touch panels 210 are adjacent to each other, the control circuit 220 may easily misjudge the user's single-finger touch as multi-finger touch.

具体实施方式detailed description
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
请参考图3，图3为本发明一实施例的触控装置300的示意图。触控装置300包含多个触控面板310A至310D以及控制电路320。控制电路320耦接于多个触控面板310。在本实施例中，触控面板310A至310D的每一个触控面板可定义的坐标范围皆为30×30，而经控制电路320处理过后的坐标如图3所示，其坐标范围涵盖了所有的触控面板310A至310D，其中触控面板310A四角的坐标分别为(0，0)、(30，0)、(0，30)及(30，30)，触控面板310B四角的坐标分别为(31，0)、(60，0)、(31，30)及(60，30)，触控面板310C四角的坐标分别为(0，31)、(30，31)、(0，60)及(30，60)，而触控面板310D四角的坐标分别为(31，31)、(61，31)、(31，60)及(60，60)。此外，控制电路320会定义触控面板310A至310D的相邻区域330(以斜线表示的区域)，而相邻区域330包含了各触控面板310A至310D与其他面板相邻的边界且距离相邻边界一预设范围内的触碰区域。以图3为例，上述预设范围例如是三个坐标单位。在此情况下，相邻区域330包含了由(27，0)、(34，0)、(27，60)及(34，60)四点所围成的区域以及由(0，27)、(60，27)、(0，34)及(60，34)四点所围成的区域。Please refer to FIG. 3 , which is a schematic diagram of a touch device 300 according to an embodiment of the present invention. The touch device 300 includes a plurality of touch panels 310A to 310D and a control circuit 320 . The control circuit 320 is coupled to the plurality of touch panels 310 . In this embodiment, the definable coordinate range of each of the touch panels 310A to 310D is 30×30, and the coordinates processed by the control circuit 320 are shown in FIG. 3 , and the coordinate range covers all The coordinates of the four corners of the touch panel 310A are (0, 0), (30, 0), (0, 30) and (30, 30), respectively, and the coordinates of the four corners of the touch panel 310B are respectively are (31,0), (60,0), (31,30) and (60,30), and the coordinates of the four corners of the touch panel 310C are (0,31), (30,31), (0,60 ) and (30,60), and the coordinates of the four corners of the touch panel 310D are (31,31), (61,31), (31,60) and (60,60) respectively. In addition, the control circuit 320 will define the adjacent area 330 (the area indicated by oblique lines) of the touch panels 310A to 310D, and the adjacent area 330 includes the boundaries between the touch panels 310A to 310D and other panels and the distance The touch area within a preset range adjacent to the boundary. Taking FIG. 3 as an example, the preset range is, for example, three coordinate units. In this case, the adjacent region 330 includes the region surrounded by (27,0), (34,0), (27,60) and (34,60) and the region surrounded by (0,27), The area surrounded by four points (60, 27), (0, 34) and (60, 34).
当触控面板310A至310D被触碰时，触控面板310A至310D会产生并输出相对的触控信号SA至SD至控制电路320。控制电路220再依据所接收到的信号，判断各触控面板310A至310D的触碰点。当控制电路320判断出在相邻区域内330有至少两个触碰点，且上述至少两个触碰点分别位于触控面板310A至310D的至少两个触控面板时，控制电路320会进一步地判断上述至少两个触碰位置之间的距离是否小于一默认值。之后，倘若控制电路320判断上述至少两个触碰位置之间的距离小于上述默认值时，控制电路320依据上述至少两个触碰点的坐标，重新定义一个新触碰点，以取代上述至少两个触碰点，并输出对应于新触碰点的信号SO。为进一步说明上述重新定义新触碰点的方式，以下将举几个例子作说明。When the touch panels 310A to 310D are touched, the touch panels 310A to 310D will generate and output relative touch signals SA to SD to the control circuit 320 . The control circuit 220 then determines the touch points of the touch panels 310A to 310D according to the received signals. When the control circuit 320 determines that there are at least two touch points in the adjacent area 330, and the at least two touch points are respectively located on at least two touch panels of the touch panels 310A to 310D, the control circuit 320 will further It is determined whether the distance between the at least two touch positions is smaller than a default value. Afterwards, if the control circuit 320 judges that the distance between the at least two touch positions is smaller than the default value, the control circuit 320 redefines a new touch point based on the coordinates of the at least two touch points to replace the at least two touch points. two touch points, and output a signal SO corresponding to the new touch point. In order to further illustrate the above-mentioned manner of redefining the new touch point, several examples are given below.
首先，倘若没有任何的触碰点落在相邻区域330或是只有单一个触碰点落在相邻区域330，则控制电路320不须重新定义一个新触碰点，因此也不会有任何的触碰点被取代，故控制电路320依据原本所判断的触碰点产生并输出对应于原本触控点的信号SO。再者，倘若控制电路320判断出有两个或更多个触碰点落在相邻区域330，则控制电路320会进一步地判断落在相邻区域330内的多个触碰点之间的距离是否小于上述的默认值。若距离小于上述的默认值，则控制电路320会重新定义一个新触碰点，以取代在相邻区域330内的多个触碰点；反之，倘若距离大于或等于上述的默认值，则控制电路320即不会重新定义一个新触碰点，故也不会有任何的触碰点被取代，而控制电路320则是依据原本所判断的触碰点产生并输出对应于原本触控点的信号SO。First of all, if no touch point falls on the adjacent area 330 or only a single touch point falls on the adjacent area 330, the control circuit 320 does not need to redefine a new touch point, so there will not be any The touch point is replaced, so the control circuit 320 generates and outputs the signal SO corresponding to the original touch point according to the originally judged touch point. Furthermore, if the control circuit 320 determines that two or more touch points fall in the adjacent area 330, the control circuit 320 will further determine the number of touch points between the multiple touch points in the adjacent area 330. Whether the distance is less than the default value above. If the distance is less than the above-mentioned default value, the control circuit 320 will redefine a new touch point to replace multiple touch points in the adjacent area 330; otherwise, if the distance is greater than or equal to the above-mentioned default value, the control circuit 320 will The circuit 320 will not redefine a new touch point, so no touch point will be replaced, and the control circuit 320 will generate and output the touch point corresponding to the original touch point according to the originally judged touch point. Signal SO.
以图3的实施例来说，控制电路320会判断出有两个或更多个触碰点落在相邻区域330的情况有两种，一种是使用者同时触碰触控面板310A至310D的其中两个触控面板的边界，另一种则是使用者同时触碰四个触控面板310A至310D的边界。在此先以第一种情形作说明，假设上述的默认值为五个坐标单位，且有两个坐标分别为(28，8)及(31，9)的触碰点落在相邻区域330内，因这两个触碰点之间的距离约为3.16(即)个坐标单位而小于上述的默认值，故控制电路320会进一步地依据这两个触碰点的坐标，重新定义一个新触碰点，以取代上述落在相邻区域330内的两个触碰点，并输出对应于新触碰点的信号SO。在本发明一实施例中，控制电路320会依据这两个触碰点的坐标，先计算这两个触碰点的重心的坐标，并依据此重心的坐标，重新定义新触碰点。详言之，因(28，8)及(31，9)两点的重心的坐标为(29.5，8.5)(即)，且由于此重心的坐标(29.5，8.5)属于触控面板310A的坐标范围，故新触碰点的坐标也会落在触控面板310A。接着，控制电路320会将重心的坐标值小数点以下无条件地进位至整数以取得新触碰点的坐标，故新触碰点的坐标为(30，9)。Taking the embodiment of FIG. 3 as an example, the control circuit 320 will determine that two or more touch points fall on the adjacent area 330. There are two situations. One is that the user simultaneously touches the touch panel 310A to The boundary between two of the touch panels 310D, and the other is the boundary between the four touch panels 310A to 310D touched by the user at the same time. Here, the first case is used as an illustration, assuming that the above-mentioned default value is five coordinate units, and two touch points whose coordinates are (28, 8) and (31, 9) respectively fall in the adjacent area 330 , because the distance between these two touch points is about 3.16 (ie ) coordinate units and less than the above-mentioned default value, so the control circuit 320 will further redefine a new touch point according to the coordinates of these two touch points to replace the above-mentioned two touch points falling in the adjacent area 330 touch point, and output a signal SO corresponding to the new touch point. In an embodiment of the present invention, the control circuit 320 first calculates the coordinates of the center of gravity of the two touch points according to the coordinates of the two touch points, and redefines a new touch point according to the coordinates of the center of gravity. In detail, because the coordinates of the center of gravity of the two points (28, 8) and (31, 9) are (29.5, 8.5) (ie ), and since the coordinates (29.5, 8.5) of the center of gravity belong to the coordinate range of the touch panel 310A, the coordinates of the new touch point also fall on the touch panel 310A. Next, the control circuit 320 unconditionally rounds up the coordinates of the center of gravity below the decimal point to an integer to obtain the coordinates of the new touch point, so the coordinates of the new touch point are (30, 9).
此外，当使用者同时触碰四个触控面板310A至310D的边界时，四个触控面板310A至310D会分别有对应的触碰点。换言之，控制电路320会判断出四个分别落于触控面板310A至310D的触碰点。假设这四个落在相邻区域330内的触碰点的坐标分别为(30，30)、(31，30)、(30，31)及(31，31)，因这四个触碰点中的任两个触碰点之间的距离皆小于上述的默认值，故控制电路320会进一步地依据这四个触碰点的坐标，重新定义一个新触碰点，以取代上述落在相邻区域330内的四个触碰点，并输出对应于新触碰点的信号SO。在本发明一实施例中，控制电路320会依据这四个触碰点的坐标，先计算这四个触碰点的重心的坐标，并依据此重心的坐标，重新定义新触碰点。详言之，因(30，30)、(31，30)、(30，31)及(31，31)四点的重心的坐标为(30.5，30.5)(即)，且由于此重心的坐标(30.5，30.5)属于触控面板310D的坐标范围，故新触碰点的坐标也会落在触控面板310D。接着，控制电路320会将重心的坐标值小数点以下无条件地进位至整数以取得新触碰点的坐标，故新触碰点的坐标为(31，31)。In addition, when the user touches the boundaries of the four touch panels 310A to 310D at the same time, the four touch panels 310A to 310D will have corresponding touch points respectively. In other words, the control circuit 320 will determine four touch points respectively falling on the touch panels 310A to 310D. Assume that the coordinates of the four touch points falling in the adjacent area 330 are (30, 30), (31, 30), (30, 31) and (31, 31), because the four touch points The distance between any two of the touch points is smaller than the above-mentioned default value, so the control circuit 320 will further redefine a new touch point according to the coordinates of these four touch points to replace the above-mentioned four touch points. Four touch points in the adjacent area 330, and output a signal SO corresponding to the new touch point. In an embodiment of the present invention, the control circuit 320 first calculates the coordinates of the center of gravity of the four touch points according to the coordinates of the four touch points, and redefines a new touch point according to the coordinates of the center of gravity. In detail, because the coordinates of the center of gravity of the four points (30, 30), (31, 30), (30, 31) and (31, 31) are (30.5, 30.5) (ie ), and since the coordinates (30.5, 30.5) of the center of gravity belong to the coordinate range of the touch panel 310D, the coordinates of the new touch point also fall on the touch panel 310D. Next, the control circuit 320 unconditionally rounds up the coordinates of the center of gravity below the decimal point to an integer to obtain the coordinates of the new touch point, so the coordinates of the new touch point are (31, 31).
请参考图4，图4为依据本发明的一实施例用以控制图3的触控装置的方法的流程图。控制触控装置300的方法包含下列步骤：Please refer to FIG. 4 , which is a flowchart of a method for controlling the touch device of FIG. 3 according to an embodiment of the present invention. The method for controlling the touch device 300 includes the following steps:

步骤S440：控制电路320判断在相邻区域330内是否有至少两个触碰点；若判断的结果是肯定的，则进行步骤S450；反之，则回到步骤S420；Step S440: the control circuit 320 determines whether there are at least two touch points in the adjacent area 330; if the result of the determination is positive, proceed to step S450; otherwise, return to step S420;
步骤S450：控制电路320判断上述至少两个触碰位置之间的距离是否小于默认值；若判断的结果是肯定的，则进行步骤S460；反之，则回到步骤S420；以及Step S450: the control circuit 320 judges whether the distance between the above-mentioned at least two touch positions is smaller than a default value; if the judgment result is affirmative, proceed to step S460; otherwise, return to step S420; and
步骤S460：控制电路320依据上述至少两个触碰点的坐标，重新定义一个新触碰点，以取代上述至少两个触碰点，并输出对应于新触碰点的信号SO。Step S460: The control circuit 320 redefines a new touch point to replace the at least two touch points according to the coordinates of the at least two touch points, and outputs a signal SO corresponding to the new touch point.
图3中的触控面板310A至310D排列成一矩阵。但本发明中的触控面板的排列方式并不以此为限。举例来说，如图5所示，本发明一实施例的触控装置500，其两个触控面板510A及510B以对角接触的方式排列，而触控装置500的控制电路520定义了触控面板510A及510B的相邻区域530(以斜线表示的区域)。其中，触控面板510A四角的坐标分别为(0，0)、(10，0)、(0，10)及(10，10)，而触控面板510B四角的坐标分别为(11，11)、(21，11)、(11，21)及(21，21)。又例如，如图6所示，本发明一实施例的触控装置600，其六个触控面板610A至610F排列成一阶梯状，而触控装置600的控制电路620定义了触控面板610A至610F的相邻区域630(以斜线表示的区域)。其中，触控面板610A至610F的右下角的坐标分别为(10，10)、(21，10)、(32，10)、(10，21)、(21，21)及(10，32)。The touch panels 310A to 310D in FIG. 3 are arranged in a matrix. However, the arrangement of the touch panels in the present invention is not limited thereto. For example, as shown in FIG. 5 , in a touch device 500 according to an embodiment of the present invention, two touch panels 510A and 510B are arranged in a diagonal contact manner, and a control circuit 520 of the touch device 500 defines touch Adjacent areas 530 (areas indicated by oblique lines) of the control panels 510A and 510B. Wherein, the coordinates of the four corners of the touch panel 510A are (0,0), (10,0), (0,10) and (10,10), respectively, and the coordinates of the four corners of the touch panel 510B are (11,11) respectively. , (21, 11), (11, 21) and (21, 21). For another example, as shown in FIG. 6 , in a touch device 600 according to an embodiment of the present invention, six touch panels 610A to 610F are arranged in a ladder shape, and the control circuit 620 of the touch device 600 defines touch panels 610A to 610F. Neighboring region 630 of 610F (the region indicated by oblique lines). Wherein, the coordinates of the lower right corners of the touch panels 610A to 610F are (10, 10), (21, 10), (32, 10), (10, 21), (21, 21) and (10, 32) respectively. .
综上所述，本发明的触控装置包含多个触控面板，而触控装置的控制电路会定义触控面板的相邻区域，并判断是否有多个触碰点落于所定义的相邻区域。当有多个触碰点落于所定义的相邻区域内时，控制电路会判断这些落于相邻区域内多个触碰点之间的距离是否小于默认值。藉此，控制电路即可正确地判断用户实际上是在进行单点触碰还是多点触碰，故当碰触点落在两个或更多个触控面板相邻的边界上时，本发明的触控装置的控制电路不会将用户单指的触碰误判为多指的触控。To sum up, the touch device of the present invention includes a plurality of touch panels, and the control circuit of the touch device defines the adjacent areas of the touch panel, and judges whether there are multiple touch points falling on the defined relative areas. adjacent area. When multiple touch points fall within the defined adjacent area, the control circuit will determine whether the distance between the multiple touch points within the adjacent area is smaller than a default value. In this way, the control circuit can correctly judge whether the user is actually performing a single-point touch or a multi-point touch, so when the touch point falls on the adjacent boundary of two or more touch panels, this The control circuit of the inventive touch control device will not misjudge the user's single-finger touch as multi-finger touch.
