The intersection of the two wires is used to obtain the touch position of the indicator. The control structure is also the sensing structure used by the resistance of the traditional touch-sensitive technology towel. The detailed sensing of such touch sensing structures is well known in the art as it is generally known in the art and will not be described here. The mode of operation of the processing circuit 11G of this embodiment will be explained with reference to FIG. FIG. 4 is an explanatory diagram of multi-touch control of the touch system of this embodiment, which is taken as an example of two-point touch. In the 4th towel, the label and the figure are the same object, the reference numeral 402 is the horizontal wire, the number 4〇4 is the vertical wire, and the symbols 406 and 408 are indicated as the indication. Things. In addition, the quadrilateral regions in which the lateral wires 402 and the longitudinal wires 404 are disposed are denoted as touch surfaces. In this case, the shape of the touch surface is a rectangle. As shown in FIG. 4, the processing circuit 110 senses the two indicators through the lateral wires 402 and the longitudinal wires 404 to obtain the touch positions of the two indicators. Since in this case, the processing circuit 110 determines that two transverse wires 402 and two longitudinal wires 404 are electrically coupled, the processing circuit 110 may consider that the reference numerals 414 and 416 may also be 201113778. The position where the indicator Yang and 408 are located, and the intersection of the above four wires (ie, the possible touch positions of the objects 406 and 408) is regarded as the first sensing result. In addition, since the shirt image sensing device 1〇6 can respectively detect the object injury and 4〇8 along the sensing routes 々π and 420, the image sensing device can just follow the sensing routes 422 and 424 respectively. The indicators 406 and 408 are sensed, and the processing circuit 110 also obtains the possible touch positions of the private objects 406 and 408 by calculating the intersection of the above sensing routes. Therefore, the processing circuit 11 认为 will consider that the points indicated by the reference numerals 410 and 412 may also be the positions where the pointers 4 〇 6 and 408 are located and the intersections of the above sensing routes (also referred to as indicators 408) The possible touch position) is considered as the second sensing result. Since in the first sensing result, only two intersection points are the actual touch positions of the indicator and Nakou, the others are ghost points, and in the second sensing result, only two intersection points are Indicating the actual touch positions of 406 and 408, the others are also ghost points. Therefore, the processing circuit 11 further obtains the intersection of the first sensing result and the second sensing result to treat the intersection as the indicators 406 and 408. Actual touch position. In this way, the touch system is not affected by ghost points and misjudges the positions of the indicators 406 and 408. It is worth mentioning that in the preferred hardware implementation of the present invention, each of the image sensing devices has an infrared (IR) illumination device, such as an infrared light emitting diode (IRLED). . In addition, each of the image sensing devices further has an infrared filter device that can only pass infrared rays, for example, an infrared filter (iR_pass fllter), so that each image sensing device can pass through the infrared filter. The light device is used to obtain an image of the touch surface. In addition, the reflective elements 112, 114 and 116 are made of a retroreflective material (retr〇_reflective matenal) to achieve a reflective effect, which is not intended to limit the invention, as long as the reflective elements 119, 114 and 116 can reflect light.

The second wire is perpendicular to the first wire, and when the finger touches the touch surface, the first wire and the second wire corresponding to the touch position of the indicator are electrically connected. The second image (4) device and the first image sensing device are used to sense the image of the touch surface. The step of the touch sensing method includes: when a first indicator and a second indicator touch the touch surface, 'obtaining the possible touch positions of the indicators through the first wire and the second wire, so that As a first sensing result, the possible touch positions of the indicators are calculated according to the indicator images sensed by the first image sensing device and the second image sensing device, so as to be the second sensing result (such as the step S502); and obtaining an intersection of the first sensing result and the second sensing result to treat the intersection as the actual touch position of the indicator (as shown in step S504). The second embodiment of the present invention provides another touch system. The touch system differs from the touch system of the first embodiment in that the touch panel of the touch system uses another touch sensing system. The structure, and the touch sensing structure is mainly composed of a plurality of longitudinal wires arranged in parallel. The sensing method of this touch system is illustrated in FIG. 6 by 201113778. FIG. 6 is an explanatory diagram of multi-touching of the touch system of the embodiment, and the touch of the touch is taken as an example. In FIG. 6, the same reference numerals as those in FIG. 1 denote the same object, and the reference numeral 404 denotes a longitudinal wire, and the numbers 4〇6 and 4〇8 denote none of the indicators. Further, the quadrangular region in which the longitudinal wires 404 are disposed is represented as a touch surface. In this example, the shape of the touch surface is a rectangle. As shown in Fig. 6, the processing circuit 11 取 passes through the longitudinal wires 4 〇 4 to obtain the one-dimensional coordinates of the two indicators as the first sensing result. This external processing circuit 110 also calculates the defects ' of the sensing paths 418, 42A, 422, and 424 as a second sensing result. Since the obtained one-dimensional coordinates are the X coordinates of the actual touch positions of the indicators 406 and 408, in the second sensing result, only two intersection points are the actual touch positions of the indicators 406 and 408, and others. Then, it is a ghost point, so the processing circuit 11 can further obtain the intersection of the first sensing result and the second sensing result to treat the intersection as the actual touch position of the pointers 406 and 408. As a result, the touch system is not affected by ghost points and misjudges the positions of the indicators 406 and 408. It is worth mentioning that even though the touch sensing structure used in the touch panel of this example is mainly composed of a plurality of parallel wires arranged in parallel, the present invention can also be implemented. By referring to the teachings of this embodiment, some basic operational steps of the touch system of this example can be summarized and illustrated in FIG. FIG. 7 is a flow chart of a touch sensing method according to an embodiment of the present invention, which is applicable to a touch system. The touch system includes a touch panel, a first image sensing device and a second image sensing device. The touch panel has a touch surface, and the touch panel adopts a touch sensing structure. The touch sensing structure includes a plurality of first conductive lines disposed in parallel. The second image sensing device and the first image sensing device are both used to sense the image of the touch [s] 12 201113778 surface. The step of the touch sensing method includes: when a first indicator and a second indicator touch the touch surface, 'obtaining one of the dimensions of the indicator through the first wire to make a first sense And measuring the possible touch positions of the indicators according to the indicator images sensed by the first image sensing device and the second image sensing device, so as to be the second sensing result (as shown in step S702) And obtaining an intersection of the first sensing result and the second sensing result to treat the intersection as the actual touch position of the indicator (as shown in step §7〇4). The third embodiment is different from the touch system of the first embodiment. The touch system has only one image sensing device. The sensing method of this touch system is illustrated in FIG. FIG. 8 is an explanatory diagram of multi-touch control of the touch system of the embodiment, and the basin system takes two-point touch as an example. In Fig. 8, the same reference numerals as those in Fig. i are denoted by the same object, the reference numeral 402 denotes a transverse wire, the reference numeral denotes a longitudinal wire, and the reference numerals 406 and 408 denote the indicators. In addition, the quadrilateral regions in which the lateral wires 402 are arranged are formed as touch surfaces. In this example, the shape of the touch surface is shown in FIG. 8. The processing circuit no senses the two indicators through the lateral wires 4〇2 and the longitudinal wires 404 to obtain the two The indication is set as the first sensing result. In addition, the processing circuit " ο also senses the above-mentioned two sensed target images by reading the sensing device 丨〇 6 “like the schematic of the image sensed by the sensing device in the second sensing device. In this figure, "δ filament is the image 13 [s] 201113778 sensing window). The indicator 8A02 forms a bright zone with a higher brightness on the image by reflecting the light from the reflective elements 114 and 116. This bright area 8A02 is the main sensing area. As for the signs 8A04 and 8A06, the dark lines caused by the indicators 406 and 408, that is, the indicator images. Please refer to Figure 8 again. Since in the first sensing result, only two intersection points are the actual touch positions of the indicators 406 and 408, and the others are ghost points, and in the first sensing result, the distribution position of the two dark lines is The positions of the indicators 406 and 408 are such that the processing circuit 11 can further obtain an intersection of the first sensing result and the second sensing result to treat the intersection as the actual touch position of the indicators 406 and 408. As a result, the touch system is not affected by ghost points and misjudges the positions of the indicators 406 and 408. It is worth mentioning that the present invention can also be implemented even if the position of the image sensing device 106 of this example is changed from the upper left corner of the touch surface to the upper right corner of the touch surface. With the teachings of this embodiment, some basic operational steps of the touch system of this example can be summarized and illustrated in FIG. FIG. 9 is a flow chart of a touch sensing method according to an embodiment of the present invention, which is applicable to a touch system. The touch system includes a touch panel and an image sensing device. The touch panel has a touch control surface, and the touch panel includes a touch sensing structure, and the touch sensing structure includes a plurality of first wires disposed in parallel and a plurality of second wires disposed in parallel. The second wire is perpendicular to the first wire, and when the first indicator and the second indicator touch the touch surface, the first wire and the second wire corresponding to the touch positions of the indicators are electrically Coupling. The image sensing device is configured to sense an image of the touch surface. The step of the touch sensing method includes: when the two indicators touch the touch surface, obtaining the possible touch positions of the indicators through the first wire and the second wire, so as to be the first The result of the sensing is '201113778', the position of the indicator image sensed by the different image sensing device in the image sensing window of the image, so as to be the second sensing result (as shown in the step) j and obtain the first sense The intersection of the second sensing result and the parent set is regarded as the actual touch position of the pointer (as shown in step S9〇4). Fourth Embodiment: This embodiment proposes another touch system. The difference between the touch system and the touch system is that the touch system has only one image device and the touch system The touch panel adopts another touch sensing sense structure, and the touch sensing structure is mainly composed of a plurality of longitudinal wires arranged in parallel. to make. The sensing method of this touch system is illustrated in FIG. Figure 10 is an explanatory diagram of multi-touch control of the touch system of the embodiment. The two-point touch is taken as an example. In Fig. 1A, the same reference numerals as in the figure i are denoted by the same object, the reference numeral 404 denotes a longitudinal wire, and the reference numerals 4〇6 and 4〇8 denote the indicators. In addition, the longitudinal wires 4 (10) are arranged to represent the touch surface. In this example, the shape of the touch surface is as follows: As shown in FIG. 10, the processing circuit 110 transmits the one-dimensional coordinates of the two indicators through the longitudinal wires 4〇4. In addition, the processing circuit 11 感 also senses the two indicators through the image sensing device 106 to calculate the image sensing window of the image sensing device 1 感 6 sensed by the image sensing device 106 . The location in . In this example, the processing circuit 1丨〇 cannot obtain the actual touch position of the pointers 406 and 408 by obtaining the intersection of the sensing results of the two sensing modes, so the processing circuit 110 changes to the above position and the above. - Historical data of the dimensional coordinates to estimate the actual touch position of the two indicators. In addition, as can be seen from Figure 10, the touch system of this architecture does not produce ghost points, [S1 15 201113778, so there will be no ghost problems. It is worth mentioning that even if the image sensing device 1〇6 of this example is changed from the upper left corner of the touch surface to the upper right corner of the touch surface, the present invention is applied. In addition, even if the touch sensing structure used in the touch panel of this example is composed of a plurality of laterally disposed transverse wires, the present invention can be expanded.
