technical field

The present invention relates to a touch device, and in particular to a touch method for determining a touch track, and a touch device using the touch method.

Background technique

Currently, touch devices are widely used as man-machine input interfaces, and touch devices can also be integrated with display devices to become touch display devices. Currently, most of the touch devices on the market are capacitive touch devices, which have multiple sensing points formed by multiple sensing lines. More precisely, a part of the plurality of sensing lines is a plurality of horizontal sensing lines, and another part of the plurality of sensing lines is a plurality of vertical sensing lines, wherein the plurality of horizontal sensing lines and the plurality of vertical sensing lines are connected to each other. Insulated, and interlaced with each other on the plane to form the plurality of sensing points.

On the other hand, Microsoft has defined the Windows Hardware Certification Kit (WHCK), so that hardware suppliers can provide hardware that complies with Microsoft's operating system. In the vertical and horizontal line drawing test items of Microsoft's Windows Hardware Certification Kit, if five 9ψ copper pillars with a distance of at least 12 mm are drawn vertically or horizontally on the touch device, the touch device needs to judge the touch The trajectory is five vertical or horizontal lines. In addition, in the diagonal line test item of Microsoft's Windows Hardware Certification Kit, if five 9ψ copper pillars with a distance of at least 15 mm are drawn diagonally on the touch device, the touch device needs to determine The touch track is five diagonal lines.

Generally speaking, the way for a capacitive touch device to determine whether a sensing point is touched is to detect the sensing amount of the sensing point, wherein the sensing amount is the capacitance change amount, and can be measured by the time before and after the sensing point is touched. Indicates the amount of voltage change. If the sensing amount of the sensing point is greater than a threshold value, it is determined that the sensing point is touched. The touch device can determine the touch track drawn by the user touching the touch device according to the situation that the plurality of sensing points are touched within a frame scanning time.

However, the touch device will be affected by factors such as noise or the difference in the value of the residual wire resistance-capacitance product, and may make a wrong judgment, causing the touch device to mistakenly disassemble a single finger with a large area of the user touching the touch device into two parts. fingers, or misjudging two close fingers as a single finger with a large area. Therefore, if the accuracy of the touch method used to determine the touch trace is insufficient, the touch device provided by the hardware supplier will not meet the specifications of the Windows hardware certification suite.

However, inventive concepts may be embodied in many different forms and should not be construed as limited to the illustrative embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the inventive concept to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity. Like numbers indicate like elements throughout.

It will be understood that, although the terms first, second, third etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another. Thus, a first element discussed below could be termed a second element without departing from the teachings of the inventive concept. As used herein, the term "or" may include any one or all combinations of more of the associated listed items, depending on the actual situation.

Please refer to FIG. 1 first. FIG. 1 is a schematic diagram of a touch device according to an embodiment of the present invention. The touch device 1 has a touch sensing unit. The touch sensing unit includes a plurality of first direction sensing lines 11 , a plurality of second direction sensing lines 12 , a front-end circuit 14 and a touch sensor 15 (Controller). The plurality of first direction sensing lines 11 and the plurality of second direction sensing lines 12 are electrically insulated from each other, the plurality of first direction sensing lines 11 are arranged parallel to each other and extend in the first direction (such as the X direction), and the plurality of second direction The sensing lines 12 are arranged parallel to each other and extend in the second direction (for example, the Y direction). The plurality of sensing lines 11 in the first direction and the sensing lines 12 in the second direction have multiple overlapped and interlaced places in the plan view, so as to A plurality of sensing points 13 are formed. The plurality of first direction sensing lines 11 are electrically connected to the front-end circuit 14 , and the front-end circuit 14 is electrically connected to the touch sensor 15 .

When the copper pillar 16 or other touch object touches at least one of the plurality of sensing points 13 , the sensing capacitance value corresponding to the touched sensing point 13 will change. Therefore, the front-end circuit 14 can obtain the sensing value when the copper pillar 16 touches the sensing point 13 , where the sensing value is used to represent the sensing capacitance change before and after the sensing point 13 is touched. In addition, in this embodiment, the horizontal distance between each sensing point 13 is at least 6 cm, and the distance between the two copper pillars 16 used to test the touch device 1 is, for example, 12 cm, but the present invention does not rely on This is the limit.

In addition, the touch sensor 15 includes multiple or one circuit to implement multiple touch methods in the embodiments of the present invention. The touch sensor 15 obtains the sensing values of the sensing points 13 in a specific scanning order (for example, scanning from top to bottom, column by column, and from left to right), and finds out a plurality of sensing points whose sensing values are greater than the sensing threshold. Next, the touch sensor 15 compares the sensing points 13 whose sensing amounts are greater than the sensing threshold with the sensing amounts of the adjacent sensing points 13 in a specific scanning sequence to determine whether the sensing amount is greater than the sensing threshold The sensing point 13 is determined as a peak sensing point, wherein the sensing points 13 adjacent to the sensing points 13 whose sensing amount is greater than the sensing threshold are determined by the operating mode, and the operating mode can be the first or the second model.

For example, in FIG. 1 , the sensing values of the two sensing points 13 touched by the copper pillar 16 are greater than the sensing threshold, and also greater than the sensing values of the adjacent sensing points 13, so the sensing values of the two sensing points 13 touched by the copper pillar 16 The sensing values of the two sensing points 13 have peak values, and the two sensing points 13 touched by the copper pillar 16 can be regarded as peak sensing points. In addition, if the operation mode is the first mode, and the first mode is, for example, the X-shaped peak finding mode, the adjacent sensing points 13 of the two sensing points 13 touched by the copper pillar 16 are the two sensing points 13 touched by the copper pillar 16. Sensing points 13 in the upper left corner, upper right corner, lower left corner and lower right corner of the first sensing point 13. If the operation mode is the second mode, and the second mode is, for example, the cross peak finding mode, the adjacent sensing points 13 of the two sensing points 13 touched by the copper pillar 16 are the two sensing points touched by the copper pillar 16 Sensing points 13 on the top, bottom, left and right of 13.

If the sensing point whose sensing amount is greater than the sensing threshold is determined as the peak sensing point, then the touch sensor 15 will forcefully not judge the multiple sensing points 13 adjacent to the peak sensing point as the multiple peak sensing points, among which The sensing point of the peak sensing point is determined by the operation mode. For example, in FIG. 1, when the default mode of the operation mode is the first mode (such as the X-shaped peak-finding mode), the right, left, upper and lower sides of the two sensing points 13 touched by the copper pillar 16 The four sensing points 13 will not be judged as peak sensing points forcibly. When the mode of the operation mode is the second mode (such as the cross peak finding mode), the four sensing points 13 in the upper right corner, upper left corner, lower right corner and lower left corner of the two sensing points 13 touched by the copper pillar 16 will be forced The ground is not judged as the peak sensing point. Then, the touch sensor 15 can determine the touch track according to the position of each peak sensing point.

In another embodiment of the present invention, the touch sensor 15 also judges whether the sensing amount of one of the plurality of sensing points 13 adjacent to the plurality of peak sensing points is greater than the peak sensing point in a specific scanning order. The amount of sensing, wherein the plurality of sensing points 13 adjacent to the peak sensing point are determined by being preset as the first or second mode according to a specific scanning sequence and operation mode. If the sensing amount of one of the plurality of sensing points adjacent to the peak sensing point is greater than the sensing amount of the peak sensing point, the peak sensing point is not judged as a peak sensing point, and the peak sensing point is The maximum sensing value of the multiple sensing points 13 adjacent to the point is determined as the peak sensing point. In other words, if the sensing value of the peak sensing point is smaller than one of the sensing values of its neighboring sensing points 13, the current peak sensing point will be displaced to the maximum sensing value of its neighboring sensing points 13. By.

For example, in FIG. 1 , it is assumed that the specific scanning order is to scan from left to right column by column from top to bottom, and the operation mode is preset as the first mode, if the sensing point touched by the copper pillar 16 If the sensing value of one of the sensing points 13 on the right side and below of 13 is greater than the sensing point 13 touched by the copper pillar 16, then the peak sensing point is judged to be the sensing point 13 on the right side and below the sensing point 13 touched by the copper pillar 16. Among the sensing points 13 , the sensing point 13 touched by the copper pillar 16 is not judged as the peak sensing point if the sensing amount is larger.

Assuming that the specific scanning sequence is to scan from top to bottom column by column and from left to right, and the operation mode is preset as the second mode, if the sensing of the lower right corner and the lower left corner of the sensing point 13 touched by the copper pillar 16 If the sensing value of one of the points 13 is greater than the sensing point 13 touched by the copper pillar 16, then the peak sensing point is judged to be the sensing point 13 in the lower right corner and the lower left corner of the sensing point 13 touched by the copper pillar 16. If the amount is larger, the sensing point 13 touched by the copper pillar 16 is not judged as the peak sensing point.

Assuming that the specific scanning sequence is to scan from left to right column by column from bottom to top, and the operation mode is preset as the second mode, if the sensing of the upper right corner and the upper left corner of the sensing point 13 touched by the copper pillar 16 If the sensing value of one of the points 13 is greater than the sensing point 13 touched by the copper pillar 16, then the peak sensing point is judged to be the sensing point 13 in the upper right corner and the upper left corner of the sensing point 13 touched by the copper pillar 16. If the amount is larger, the sensing point 13 touched by the copper pillar 16 is not judged as the peak sensing point.

In another embodiment of the present invention, the touch sensor 15 may also use a peak merge function to selectively not determine at least one of the plurality of peak sensing points as a peak sensing point. For example, if the difference between the sensing amount of at least one sensing point between two peak sensing points and the sensing amount of the two peak sensing points is not large (that is, the difference between the two peak sensing points and at least The sensing value of one sensing point changes very little), then the peak fusion function can combine the two peak sensing points into one peak sensing point.

Since the operation mode can be the first mode or the second mode, and the first mode and the second mode are suitable for determining the touch track of different lines (horizontal, vertical or diagonal), so in another implementation of the present invention In an example, the touch sensor 15 can also judge whether the operation mode should be switched or not need to be switched according to the direction of the plurality of peak sensing points, wherein the direction is used to determine whether the touch track is a horizontal or vertical line or a diagonal line. One, if the current operation mode is not suitable for determining the touch trajectory, the operation mode can be switched according to the determined direction. If the touch sensor 15 judges that the operation mode should be switched, then the operation mode is switched correspondingly, and the touch sensor 15 will search for the peak sensing point in the switched operation mode again, and according to the peak sensing point found again to determine the touch trajectory. The way to obtain the direction will be introduced in detail in the following content, so I won’t go into details here.

Please refer to FIG. 2A and FIG. 2B. FIG. 2A is a schematic diagram of the touch device according to the embodiment of the present invention using the first mode to determine the peak sensing point, and FIG. 2B is the touch device according to the embodiment of the present invention using the second mode to determine the peak sensing point. point diagram. In FIG. 2A and FIG. 2B , the first mode and the second mode are X-shaped peak-finding mode and cross-shaped peak-finding mode respectively. However, it should be noted that the types of the first mode and the second mode are not intended to limit the present invention.

In FIG. 2A , when the operation mode is the first mode, the touch sensor will compare whether the sensing value dv(x, y) of the sensing point at the position (x, y) is greater than the sensing threshold. If the sensing value dv(x,y) of the sensing point at position (x,y) is greater than the sensing threshold, the touch sensor will compare the sensing value dv(x,y) of the sensing point at position (x,y) with the position (x-1, y-1), (x+1, y-1), (x-1, y+1), (x+1, y+1) induction point dv(x-1 ,y-1), dv(x+1,y-1), dv(x-1,y+1), dv(x+1,y+1). If the induction value dv(x, y) of the sensing point at position (x, y) is greater than the position (x-1, y-1), (x+1, y-1), (x-1, y+1) ), (x+1, y+1) sensing points dv(x-1, y-1), dv(x+1, y-1), dv(x-1, y+1), dv(x+1, y+1), the touch sensor determines the sensing point at position (x, y) as the peak sensing point. In other words, when the operation mode is the first mode, the touch sensor will compare the sensing points whose sensing values are greater than the sensing threshold and the sensing values of the four sensing points in the upper left corner, upper right corner, lower left corner, and lower right corner to determine whether The sensing point whose sensing amount is greater than the sensing threshold is determined as a peak sensing point.

In FIG. 2B , when the operation mode is the second mode, the touch sensor will compare whether the sensing value dv(x, y) of the sensing point at the position (x, y) is greater than the sensing threshold. If the sensing value dv(x,y) of the sensing point at position (x,y) is greater than the sensing threshold, the touch sensor will compare the sensing value dv(x,y) of the sensing point at position (x,y) with the position (x, y-1), (x, y+1), (x-1, y), (x+1, y) sensing points dv(x, y-1), dv(x, y+1), dv(x-1,y), dv(x+1,y). If the induction value dv(x, y) of the sensing point at position (x, y) is greater than the position (x, y-1), (x, y+1), (x-1, y), (x+ 1, y) sensing points dv(x, y-1), dv(x, y+1), dv(x-1, y), dv(x+1, y), then the touch sensor Determine the sensing point at position (x, y) as the peak sensing point. In other words, when the operation mode is the second mode, the touch sensor will compare the sensing points whose sensing amount is greater than the sensing threshold and the sensing amounts of the four sensing points on the left, right, bottom, and top to determine whether the sensing amount is greater than The sensing point of the sensing threshold is determined as a peak sensing point.

Incidentally, the first mode is suitable for determining a touch track for drawing a vertical or horizontal line, whereas the second mode is suitable for determining a touch track for drawing a diagonal line. Therefore, the touch sensor 15 can determine whether the touch track is one of drawing a vertical or horizontal line and drawing a diagonal line according to the direction. If it is judged from the direction that the touch track is a vertical or horizontal line, and the operation mode is the first mode, the touch sensor 15 will maintain the first mode, that is, there is no need to switch the operation mode. If it is judged by the direction that the touch track is a vertical or horizontal line, and the operation mode is the second mode, the touch sensor 15 will switch to the first mode to obtain a more accurate touch track. If it is judged from the direction that the touch track is a diagonal line and the operation mode is the second mode, the touch sensor 15 will maintain the second mode, that is, there is no need to switch the operation mode. If it is determined by the direction that the touch track is a diagonal line and the operation mode is the first mode, the touch sensor 15 will switch to the second mode to obtain a more accurate touch track.

Please refer to FIG. 3 , which is a flow chart of a touch control method according to an embodiment of the present invention. First, in step S31 , the touch sensor obtains the sensing values of each sensing point in a specific scanning order, and finds out a plurality of sensing points whose sensing values are greater than a sensing threshold. The specific scanning order is, for example, scanning from top to bottom column by column and from left to right, but the invention is not limited thereto. In other embodiments, the specific scanning order may also be, for example, scanning from top to bottom, column by column, and from right to left.

Next, in step S32, the touch sensor compares the sensing point whose sensing amount is greater than the sensing threshold value with the sensing values of multiple adjacent sensing points in a specific scanning order to determine whether the sensing amount is greater than the sensing threshold value. The sensing point is determined to be a peak sensing point, wherein a plurality of sensing points adjacent to the sensing point whose sensing amount is greater than a sensing threshold are determined by an operation mode, and the operation mode is the first mode or the second mode. If the sensing values of the sensing points whose sensing values are greater than the sensing threshold are all greater than the sensing points adjacent to the sensing point (for example: when the operation mode is the first mode, the adjacent sensing points are the upper left corner , the upper right corner, the lower left corner, and the lower right corner; or, when the operation mode is the second mode, the adjacent multiple sensing points are the four sensing points on the left, right, bottom, and top) , then the sensing point where the sensing amount is greater than the sensing critical value is judged as the peak critical point. If the sensing values of the sensing points whose sensing values are greater than the sensing critical value are not all greater than the sensing values of multiple sensing points adjacent to the sensing point, then the sensing points whose sensing values are greater than the sensing critical value are not selected. It is judged as the peak sensing point.

Next, in step S33, if the sensing point whose sensing amount is greater than the sensing threshold is determined as the peak sensing point, the touch sensor will forcibly not judge the multiple sensing points adjacent to the peak sensing point as the multiple peak sensing points. points, wherein a plurality of sensing points adjacent to the peak sensing point is determined by the operation mode. When the operation mode is the first mode, the sensing points adjacent to the peak sensing point are sensing points above, below, left and right of the peak sensing point. When the operation mode is the second mode, the plurality of sensing points adjacent to the peak sensing point are sensing points in the upper right corner, upper left corner, lower left corner and lower right corner of the peak sensing point. Step S33 can be properly selected to use or not. Then, in step S35 , the touch sensor determines the touch trajectory according to the positions of the peak sensing points.

For example, when the operation mode is the first mode, and the specific scanning order is to scan from left to right from top to bottom column by column, then in step S32, a plurality of adjacent sensing points in the same column may be scanned It is judged as a peak sensing point, or a plurality of adjacent sensing points in the same row may be judged as a peak sensing point, for example, in step S32, the sensing points on the right, left, above, and below of the sensing point of the judged peak sensing point Points may also be judged as peak sensing points. Therefore, in step S33 , the touch sensor scans the peak sensing points according to a specific scanning order, so that the sensing points on the right, left, upper, and lower sides of the currently scanned peak sensing points are not forcibly determined as peak sensing points. When the operation mode is the second mode, and the specific scanning sequence is scanning from left to right column by column from top to bottom, then in step S32, multiple sensing points adjacent to the same diagonal line may be judged as For peak sensing points, for example, in step S32, sensing points in the upper right corner, lower left corner, upper left corner, and lower right corner of the sensing points that are judged as peak sensing points may also be judged as peak sensing points. Therefore, in step S33, the touch sensor scans the peak sensing points according to a specific scanning order, so that the sensing points in the upper right corner, lower left corner, upper left corner, and lower right corner of the currently scanned peak sensing points are forcibly not judged as peak sensing point

Please note here that the touch control method in FIG. 3 may further include step S34. In step S34 , the touch sensor selectively determines whether the plurality of peak sensing points are reserved as peak sensing points according to the peak fusion function. Then, after step S34, step S35 will be executed. The peak fusion function is used to judge the change status of the sensing quantities of two peak sensing points and multiple sensing sensing quantities between them, so as to determine whether to merge the two peak sensing points into one peak sensing point. Please note here that step S34 is not a necessary step of the touch method in FIG. 3 , and it can also be removed from the touch method in FIG. 3 .

Next, please refer to FIG. 4A and FIG. 4B . FIG. 4A and FIG. 4B are schematic diagrams of sensing quantities of multiple sensing points in a touch device according to an embodiment of the present invention. In the embodiment of FIG. 4A and FIG. 4B , the operation mode is the first mode, and the specific scanning order is scanning from left to right from top to bottom column by column, the touch sensor uses the touch method of FIG. 3 , and the scribing The test method uses five copper pillars with a center spacing of 12, 12, 12, 12 and 24 cm to carry out vertical marking.

In Figure 4A, the sensing values of multiple sensing points at positions (X ₁ , Y ₁ )～(X ₁₀ , Y ₁₀ ) are greater than the critical sensing value, and the sensing values at positions (X ₁ , Y ₁ )～(X ₁₀ , Y ₁₀ ) The sensing amount of each of the plurality of sensing points is greater than the sensing amount of the sensing points in the upper left corner, upper right corner, lower left corner, and lower right corner, so the positions (X ₁ , Y ₁ )～(X ₁₀ , Y ₁₀ ) are more A sensing point is determined as a peak sensing point in the above step S32. Next, in step S33, the touch sensor scans a plurality of peak sensing points at positions (X ₁ , Y ₁ )～(X ₁₀ , Y ₁₀ ) according to a specific scanning order, and scans the current peak sensing points above, The sensing points below, on the right, and on the left are forcibly not judged as peak sensing points (as shown in FIG. 4B ).

For example, the peak sensing point at the position (X ₁ , Y ₁ ) in FIG. 4B will be scanned first, although the sensing point on the right (the sensing point at the position (X ₂ , Y ₂ )) is determined to be the peak value in step S32 However, in step S33, the sensing point at position (X ₂ , Y ₂ ) in FIG. 4B is forcibly not judged as the peak sensing point. Also, since the sensing point at position (X ₂ , Y ₂ ) is no longer judged as a peak sensing point, the sensing point at position (X ₃ , Y ₃ ) will not be judged as the sensing point at position (X ₂ , Y ₂ ). Because of the influence of the peak sensing point, it is not judged as the peak sensing point, so the sensing point at the position (X ₃ , Y ₃ ) can be judged as the peak sensing point. Similarly, it can be known that in FIG. 4B , other sensing points (position (X ₄ , Y ₄ ), (X ₆ , Y ₆ ), (X ₈ , Y ₈ ) and ( The sensing point of X ₁₀ , Y ₁₀ ) will not be judged as the peak sensing point forcibly in step S33.

Please refer to FIG. 5 . FIG. 5 is a schematic diagram of the touch track of the touch device according to the embodiment of the present invention presenting vertical lines according to the foregoing implementation manner. When the user draws a line vertically on the touch device, the touch track in FIG. 3 is determined as shown in FIG. 5 when the operation mode of the touch method in FIG. 3 is the first mode. In addition, other embodiments of the present invention also propose another touch method, which can improve the slightly jittery touch track in FIG. 5 .

Please refer to FIG. 6 , which is a flowchart of a touch control method according to another embodiment of the present invention. The touch control method in FIG. 6 includes steps S61-S65, wherein steps S61-S63 and step S65 are the same as steps S31-S33 and step S35 in FIG. 3 respectively, so the content of the same steps will not be repeated. In step S64, the touch sensor judges in a specific scanning order whether the sensing amount of one of the plurality of sensing points adjacent to the plurality of peak sensing points is greater than the sensing amount of the peak sensing point, if the peak If the sensing amount of one of the plurality of sensing points adjacent to the sensing point is greater than the sensing amount of the peak sensing point, the peak sensing point is not judged as the peak sensing point, and all the sensing points adjacent to the peak sensing point are The maximum sensing value of the plurality of sensing points is determined as the peak sensing point, wherein the plurality of sensing points adjacent to the peak sensing point are preset as the first or the first according to the specific scanning order and operation mode determined by the two modes.

When the specific scanning sequence is scanning from left to right column by column from top to bottom, and the operation mode is preset as the first mode, the multiple sensing points adjacent to the peak sensing point here are the peak sensing points The two sensing points on the right and below. When the specific scanning sequence is to scan from left to right column by column from top to bottom, and the operation mode is preset as the second mode, the multiple sensing points adjacent to the peak sensing point here are the peak sensing points Two sensing points in the lower right and lower left corners.

More specifically, in step S62 , multiple sensing points adjacent to the sensing point determined as the peak sensing point may also be determined as the peak sensing point. Next, in step S63, the touch sensor does not determine the multiple sensing points near the currently scanned peak sensing point as peak sensing points in a specific scanning order, so multiple sensing points near the currently scanned peak sensing point The sensing amount of the point may be greater than the sensing amount of the peak sensing point, however, the touch sensor does not judge it as a peak sensing point. Therefore, in step S64, the touch sensor scans all the peak sensing points again in a specific scanning order, and checks whether at least one of the sensing values of at least one of the adjacent sensing points of the currently scanned peak sensing point is greater than The sensing amount of the peak sensing point scanned so far.

If at least one of the sensing values of the multiple sensing points adjacent to the currently scanned peak sensing point is greater than the sensing value of the currently scanned peak sensing point, the touch sensor will use the currently scanned peak sensing point adjacent The one with the largest sensing value of multiple sensing points is judged as the peak sensing point, while the currently scanned peak sensing point is not judged as the peak sensing point. In this way, through step S64 , the accuracy of determining the touch trajectory by the touch method in FIG. 6 is higher than the accuracy of determining the trajectory by the touch method in FIG. 3 . In addition, it should be noted that the touch control method in FIG. 6 may further include step S34 in FIG. 3 , and the execution sequence of step S34 is between steps S64 and S65.

Please refer to FIGS. 7A to 7C , which are schematic diagrams of sensing values of multiple sensing points in a touch device according to another embodiment of the present invention. In the embodiment of FIG. 7A-FIG. 7C, the operation mode is preset as the first mode, and the specific scanning order is scanning from left to right from top to bottom column by column, and the touch sensor uses the touch method in FIG. 6 , and The scribe test method uses five copper pillars with center spacings of 12, 12, 12, 12 and 24 centimeters to perform vertical scribes.

In FIG. 7A, a plurality of sensing points at positions (X ₁ , Y ₁ )～(X ₁₀ , Y ₁₀ ) are determined as peak sensing points in the above step S62, and then in step S63, the touch sensor is determined according to the specified Scanning is performed in the order of scanning, and the sensing points above, below, right, and left of the peak sensing point currently scanned are forcibly not judged as peak sensing points. Therefore, the peak sensing point at the position (X ₁ , Y ₁ ) in FIG. 7B will be scanned first, although the sensing point on the right (the sensing point at the position (X ₂ , Y ₂ )) is determined to be the peak sensing point in step S62 point, but in step S63, the sensing point at position (X ₂ , Y ₂ ) in FIG. 7B is forcibly not judged as the peak sensing point. Also, since the sensing point at position (X ₂ , Y ₂ ) is no longer judged as a peak sensing point, the sensing point at position (X ₃ , Y ₃ ) will not be judged as the sensing point at position (X ₂ , Y ₂ ). Because of the influence of the peak sensing point, it is not judged as the peak sensing point, so the sensing point at the position (X ₃ , Y ₃ ) can be judged as the peak sensing point. Similarly, it can be seen that in FIG. 7B , other sensing points (position (X ₄ , Y ₄ ), (X ₆ , Y ₆ ), (X ₈ , Y ₈ ) and ( The sensing point of X ₁₀ , Y ₁₀ ) will not be judged as the peak sensing point forcibly in step S63.

Please note here that since the operation mode is preset as the first mode, and the scanning sequence is from top to bottom, column by column, and from left to right, even if the sensing point on the right side of the peak sensing point and the sensing point below are currently scanned One of the values is greater than the sensing value of the peak sensing point scanned at present, but in step S63, the sensing points to the right and below of the peak sensing point scanned at present are not judged as peak sensing points forcibly, thus resulting in a situation as shown in Fig. 5's touch track has a slight jitter. Therefore, it is necessary to check whether one of the sensing values scanned to the right and below the peak sensing point is greater than the sensing value of the currently scanned peak sensing point to determine whether the current peak sensing point is not judged as a peak sensing point. The peak sensing point is judged to be the one whose sensing value is greater than the sensing value of the sensing point on the right and below the peak sensing point is greater than that of the peak sensing point. In this way, the slightly jittering situation of the touch track can be effectively improved.

On the other hand, it can be seen from the above that in step 64, the plurality of sensing points adjacent to the peak sensing point are determined according to the specific scanning sequence and operation mode preset as the first mode or the second mode. If the scanning sequence is to scan from right to left column by column from top to bottom, and the operation mode is preset as the first mode, then one of the sensing values to the left of the peak sensing point and the sensing point below is greater than At present, those who scan the sensing amount of the peak sensing point will not be judged as the peak sensing point. Therefore, in this case, the plurality of sensing points adjacent to the peak sensing point are the sensing points to the left and below of the peak sensing point .

If the scanning sequence is to scan from left to right column by column from bottom to top, and the operation mode is preset as the first mode, then one of the sensing values of the sensing points above and to the right of the peak sensing point is currently scanned to be greater than At present, those who scan the sensing amount of the peak sensing point will not be judged as the peak sensing point, therefore, in this case, the plurality of sensing points adjacent to the peak sensing point are the sensing points on the right side and above the peak sensing point . If the scanning sequence is to scan from right to left column by column from bottom to top, and the operation mode is preset as the first mode, then one of the sensing values to the left of the peak sensing point and the sensing point above is greater than At present, those who scan the sensing amount of the peak sensing point will not be judged as the peak sensing point, therefore, in this case, the plurality of sensing points adjacent to the peak sensing point are the sensing points on the left and above of the peak sensing point .

As shown in FIG. 7C, in step S64, the peak sensing point at position (X ₁ , Y ₁ ) will be scanned first, because the sensing point on the right side of the peak sensing point at position (X ₁ , Y ₁ ) (position (X 1 ) ₂ , Y ₂ ) sensing point) is greater than the sensing value of the peak sensing point at position (X ₁ , Y ₁ ), therefore, the peak sensing point at position (X ₁ , Y ₁ ) is not judged as the peak sensing point , and the peak sensing point of the sensing point (X ₂ , Y ₂ ) is determined as the peak sensing point. Then, the peak sensing point at position (X ₃ , Y ₃ ) will be scanned, but the sensing amount of the sensing point on the right and below the peak sensing point at position (X ₃ , Y ₃ ) is not greater than that at position (X ₃ , Y 3 ) ₃ ), the peak sensing point at position (X ₃ , Y ₃ ) need not be judged as the peak sensing point. Similarly, it can be seen that the peak sensing point at position (X ₉ , Y ₉ ) will not be judged as the peak sensing point, and the peak sensing point at the sensing point at position (X ₁₀ , Y ₁₀ ) will be judged as the peak sensing point. In addition, The peak sensing points at the positions (X ₅ , Y ₅ ) and (X ₇ , Y ₇ ) need not be judged as peak sensing points.

Please refer to FIG. 8A to FIG. 8C , which are schematic diagrams of sensing quantities of multiple sensing points in a touch device according to another embodiment of the present invention. In the embodiment shown in FIG. 8A to FIG. 8C , the operation mode is preset as the second mode, and the specific scanning sequence is to scan from left to right or from right to left from top to bottom, and the touch sensor uses the The touch method and the scribing test method use five copper pillars with a center spacing of 12, 12, 12, 12 and 24 cm to carry out diagonal scribing.

In FIG. 8A , multiple sensing points at positions (X ₁ , Y ₁ )～(X ₅ , Y ₅ ) are determined as peak sensing points in the above step S62, and then in step S63, the touch sensor is determined according to the specified Scanning is performed in the order of scanning, and the sensing points currently scanned to the upper left corner, lower right corner, upper right corner, and lower left corner of the peak sensing points are not judged as peak sensing points forcibly. Therefore, when the peak sensing point at position (X ₃ , Y ₃ ) is scanned in FIG. 8B , although the sensing point at its lower left corner (sensing point at position (X ₂ , Y ₂ )) is judged to be the peak value in step S62 However, in step S63, the sensing point at position (X ₂ , Y ₂ ) in FIG. 8B is forcibly not judged as the peak sensing point.

Please note here that since the operation mode is preset as the second mode, and the scanning sequence is from top to bottom, column by column, and from left to right, even if the sensing points in the lower right corner and lower left corner of the peak sensing point are currently scanned One of the sensing values is greater than the sensing value of the peak sensing point scanned at present, but step S63 forcibly judges the sensing point at the lower right corner and the lower left corner of the peak sensing point as the peak sensing point, so It may cause slight jitter in the final judged touch track. Therefore, it is necessary to check whether one of the sensing values of the sensing points in the lower right corner and the lower left corner of the peak sensing point currently scanned is greater than the sensing amount of the peak sensing point currently scanned to determine whether the current peak sensing point is not judged as The peak sensing point and the peak sensing point are determined as the peak sensing point where the sensing amount of the sensing point at the lower right corner and the lower left corner of the peak sensing point is greater than the sensing amount of the peak sensing point. In this way, the slightly jittering situation of the touch track can be effectively improved.

On the other hand, it can be seen from the above that in step 64, the plurality of sensing points adjacent to the peak sensing point are determined according to the specific scanning sequence and operation mode preset as the first mode or the second mode.

If the scanning order is to scan from left to right or from right to left from bottom to top column by column, and the operation mode is preset to the second mode, then the current scan to the upper right corner of the peak sensing point and the upper left corner of the sensing point One of the sensing values that is greater than the sensing value of the currently scanned peak sensing point will not be judged as a peak sensing point. Therefore, in this case, the plurality of sensing points adjacent to the peak sensing point are peak sensing points The sensing points in the upper right and upper left corners of the

As shown in FIG. 8C , in step S64, the peak sensing point at position (X ₅ , Y ₅ ) will be scanned first, but the sensing of the lower right and lower left corners of the peak sensing point at position (X ₅ , Y ₅ ) The sensing amount of the point is not greater than the sensing amount of the peak sensing point at position (X ₅ , Y ₅ ), so the peak sensing point at position (X ₅ , Y ₅ ) does not need not be judged as the peak sensing point. Then, the peak sensing point at position (X ₄ , Y ₄ ) will be scanned, but the sensing amount of the sensing point at the lower right corner and lower left corner of the peak sensing point at position (X ₄ , Y ₄ ) is not greater than that of the sensing point at position (X 4 , Y ₄ ). , Y ₄ ), the peak sensing point at position (X ₄ , Y ₄ ) does not need not be judged as the peak sensing point. Then, when the peak sensing point at position (X ₃ , Y ₃ ) is scanned, the sensing point (position (X ₂ , Y ₂ ) at the lower left corner of the peak sensing point at position (X ₃ , Y ₃ ) point) is greater than that of the peak sensing point at position (X ₃ , Y ₃ ), therefore, the peak sensing point at position (X ₃ , Y ₃ ) is not judged as the peak sensing point, but (X ₂ , The peak sensing point of the sensing point of Y ₂ ) is determined as the peak sensing point. Afterwards, the peak sensing point at position (X ₁ , Y ₁ ) will be scanned, but the sensing amount of the sensing point at the lower right corner and lower left corner of the peak sensing point at position (X ₁ , Y ₁ ) is not greater than that at position (X _{1 )} ,Y ₁ ), the peak sensing point at position (X ₁ ,Y ₁ ) does not need not be judged as the peak sensing point. Please refer to FIG. 9A and FIG. 9B. FIG. 9A is a schematic diagram of a touch track of a touch device according to another embodiment of the present invention showing a vertical line according to the above-mentioned embodiment. FIG. 9B is a touch device according to another embodiment of the present invention. According to the foregoing embodiments, a schematic diagram of a touch track with diagonal lines is presented, wherein the operation mode in FIG. 9A corresponds to the first mode, and the operation mode in FIG. 9B corresponds to the second mode. From the touch traces in FIGS. 9A and 9B , it can be known that the touch control method in FIG. 6 can effectively improve the slightly jittery touch trace determined by the touch control method in FIG. 3 .

In addition, the first mode is suitable for determining a touch track for drawing a vertical or horizontal line, and the second mode is suitable for determining a touch track for drawing a diagonal line. When the current operation mode is not suitable for determining the direction of the current touch track, it is necessary to further switch the operation mode to obtain a more accurate touch track. Therefore, other embodiments of the present invention propose another touch method, which can check whether the currently used operation mode needs to be switched to obtain a more accurate touch track.

Please refer to FIG. 10 , which is a flowchart of a touch control method according to another embodiment of the present invention. The touch control method in FIG. 10 includes steps S91-S97, wherein steps S91-S94 and step S97 are the same as steps S61-S64 and step S65 in FIG. 6 respectively, so the content of the same steps will not be repeated. In step S95 , the touch sensor determines whether the operation mode should be switched or not, according to a direction of the plurality of peak sensing points. If it is determined that the operation mode should be switched, step S96 is executed. If it is determined that the operation mode does not need to be switched, step S97 is executed. In step S96, the operation mode is switched, for example, switched from the first mode to the second mode, or switched from the second mode to the first mode. After step S96, steps S91-S94 are re-executed, that is, the plurality of peak sensing points are re-obtained in the switched operation mode. It is worth mentioning that the touch control method in FIG. 10 may also include step S34 in FIG. 3 , and the execution sequence of step S34 is between steps S94 and S95. In a word, the touch control method in FIG. 10 is not intended to limit the present invention .

It is worth noting that the direction can be used to determine whether the touch track is a horizontal or vertical line or a diagonal line, and the first and second modes are respectively suitable for determining the touch track of a horizontal or vertical line or a diagonal line, so You can decide whether you need to switch the operation mode or maintain the current operation mode through the direction. When the operation mode is the second mode, and the direction judgment touch track is a horizontal or vertical line, the operation mode should be switched to the first mode. When the operation mode is the first mode, and the direction judgment touch track is a diagonal line, the operation mode should be switched to the second mode. When the operation mode is the first mode, and the direction of the judgment touch track is a horizontal or vertical line, the operation mode does not need to be switched. When the operation mode is the second mode, and the direction judgment touch track is a diagonal line, the operation mode does not need to be switched. Please note here that the way of obtaining the above trend is not intended to limit the present invention, and any implementation that can determine the direction of the touch track can be applied in the present invention.

For example, the above trend may be a slope obtained by calculating the positions of the plurality of peak values, and the slope may be used to determine whether to switch the operation mode. If the slope is small, the touch trace is horizontal or vertical, so the operation mode should be switched to the first mode or maintained in the first mode. If the slope is larger, the touch trace is diagonal, so the operation mode should be switched to the second mode or maintained in the second mode.

Furthermore, if the absolute difference |Dx-Dy| of the sum of the horizontal distances Dx and the sum of the vertical distances Dy between each of the plurality of peak sensing points and one of them is smaller than a specific value THD, it means that the slope is relatively large , so it can be judged that the operation mode should be switched to the second mode or maintained in the second mode. If the absolute difference |Dx-Dy| of the sum of the horizontal position distance Dx and the sum of the vertical distance Dy between each of the plurality of peak sensing points and one of them is not less than a specific value THD, it means that the slope is small, so it is judged The operation mode should be switched to the first mode or maintained in the first mode. The calculation method of the horizontal distance sum Dx and the vertical distance sum Dy of each of the plurality of peak sensing points and one of them can be as follows, Dx=(Σ|X _i -X _j |) and Dy=(Σ |Y _i -Y _j |), where i is not equal to j, and i is the index value of one of the peak sensing points, and j is the index value of other multiple peak sensing points.

In other embodiments of the present invention, the above trend may also be determined by the sensing values of multiple sensing points adjacent to each of the multiple peak sensing points, wherein the multiple sensing points adjacent to the peak sensing point are determined by a specific The scan order is determined. When the specific scanning sequence is to scan from top to bottom (or bottom to top) from left to right column by column, the multiple sensing points adjacent to the peak sensing point are the right side, the lower right corner and the The three sensing points in the upper right corner. When the specific scanning sequence is to scan from right to left from top to bottom (or from bottom to top), the multiple sensing points adjacent to the peak sensing point are the left side, the lower left corner and the left side of the peak sensing point. The three sensing points in the upper left corner.

One implementation manner of determining the direction by the sensing values of the sensing points adjacent to each of the peak sensing points is described as follows, and the present invention is not limited thereto. When the specific scanning sequence is to scan from top to bottom (or from bottom to top) column by column and from left to right, and the sensing amount of the sensing point on the right of any one of the plurality of peak sensing points is less than the The sensing amount of the sensing point at the lower right corner or the upper right corner of the peak sensing point indicates that the direction of the touch track is a diagonal line, so it is judged that the operation mode is switched to the second mode or remains in the second mode. When the sensing amount of the sensing point on the right of each of the plurality of peak sensing points is greater than or equal to the sensing amount of the sensing point in the lower right corner and the upper right corner of the peak sensing point, it means that the direction of the touch track is horizontal or a vertical line, so it is judged that the operation mode is switched to the first mode or remains in the first mode.

In addition, another implementation manner in which direction is determined by sensing quantities of sensing points adjacent to each of the peak sensing points is described as follows, and the present invention is not limited thereto. When the sensing amount of the sensing point on the right of the plurality of peak sensing points is smaller than the sensing amount of the sensing point in the lower right corner or upper right corner of the peak sensing point is greater than or equal to the sensing amount of the right sensing point of the plurality of peak sensing points If the sensing amount of the point is greater than the sensing amount of the sensing point in the lower right corner and upper right corner of the peak sensing point, it means that the direction of the touch track is diagonal, so the operation mode should be switched to the second mode or maintained in the second mode. model. When the sensing amount of the sensing point on the right of the plurality of peak sensing points is smaller than the sensing amount of the sensing point in the lower right corner or upper right corner of the peak sensing point is less than the sensing amount of the sensing point on the right of the plurality of peak sensing points If the sensing amount is greater than the sensing amount of the sensing points in the lower right corner and upper right corner of the peak sensing point, it means that the direction of the touch track is a horizontal or vertical line, so the operation mode should be switched to the first mode or maintained in the first mode .

FIG. 11 is a schematic diagram of sensing quantities of multiple sensing points in a touch device according to another embodiment of the present invention. In the embodiment of FIG. 11 , the operation mode is the first mode, and the specific scanning sequence is to scan from top to bottom column by column and from left to right. The touch sensor uses the touch method in FIG. 10 , and the scribing test method is Five copper pillars with center spacing of 12, 12, 12, 12 and 24 centimeters are used for vertical line scribing. In Fig. 11, the positions of multiple peak sensing points are (X ₁ , Y ₁ ), (X ₂ , Y ₂ ), (X ₃ , Y ₃ ), (X ₄ , Y ₄ ), (X ₅ , _Y5 ).

The description is made by taking as an example that the trend is the slope calculated from the positions induced by the multiple peaks. The sum Dx of the horizontal distance between each of the multiple peak sensing points and one of them (Dx=(|X ₂ -X ₁ |+|X ₃ -X ₁ |+|X ₄ -X ₁ |+|X ₅ - X ₁ |)=1+3+5+10) is 19, and the sum of vertical distances Dy(Dy=(|Y ₂ -Y ₁ |+|Y ₃ -Y ₁ |+|Y ₄ -Y ₁ |+|Y ₅ -Y ₁ |)=0+0+0+0) is 0. If it is assumed that the specific value THD is 10, then the absolute difference |Dx-Dy|(|Dx-Dy|= 19) If THD is not less than a certain value, it means that the slope is small (the direction of the touch track is a horizontal or vertical line), so it is judged that the operation mode should maintain the first mode.

In addition, it is described by taking the determination of the sensing values of a plurality of sensing points adjacent to each of the plurality of peak sensing points as an example. The sensing value of the sensing point on the right of the peak sensing point at (X ₁ , Y ₁ ) (the sensing value is c1, in hexadecimal) is greater than the upper right corner of the peak sensing point at (X ₁ , Y ₁ ) and The sensing amount of the sensing point in the lower right corner (the sensing amounts are 19 and 2a respectively). The sensing value of the sensing point on the right of the peak sensing point at (X ₂ , Y ₂ ) (the sensing value is b4) is greater than that of the sensing points at the upper right and lower right corners of the peak sensing point at (X ₂ , Y ₂ ) Sensitivity (the sensing quantity is 15 and 24 respectively). The sensing amount (a9) of the right sensing point of the peak sensing point at position (X 3 , Y ₃ ) _is greater than that of the sensing point at the upper right corner and lower right corner of the peak sensing point at position (X ₃ , Y ₃ ) Inductive quantity (inductive quantity is d and 27 respectively). The sensing amount (a1) of the right sensing point of the peak sensing point at position (X ₄ , Y ₄ ) is greater than that of the sensing point at the upper right corner and lower right corner of the peak sensing point at position (X ₄ , Y ₄ ) Sensitivity (the sensing quantity is 2 and 31 respectively). The sensing value (the sensing value is 0) of the sensing point on the right of the peak sensing point at position (X 5 , Y 5 ₎ is equal to that of the sensing point at the upper right corner and the lower right corner of the peak sensing point at position (X ₅ , Y _{5 )} . Inductive quantity (inductive quantity is 0 and 0 respectively).

If the rule adopted is: if the sensing amount of the sensing point on the right of any one of the plurality of peak sensing points is smaller than the sensing amount of the sensing point in the lower right corner or upper right corner of the peak sensing point, then the touch track is judged and if the sensing values of the sensing points on the right side of all the peak sensing points are greater than or equal to the sensing values of the sensing points in the lower right corner or upper right corner of the peak sensing points, then the touch track is judged The direction is horizontal or vertical. Therefore, in the above situation, the touch sensor determines that the operation mode should maintain the first mode.

FIG. 12A and FIG. 12B are schematic diagrams of sensing quantities of multiple sensing points in a touch device according to another embodiment of the present invention. In the embodiment of FIG. 12A , the operation mode is preset as the first mode, and the specific scanning order is scanning from top to bottom column by column and from left to right. The touch sensor uses the touch method in FIG. 10 , and the scribing test The method uses five copper pillars with center spacing of 12, 12, 12, 12 and 24 cm to carry out diagonal marking. In FIG. 12A , the positions of the multiple peak sensing points are (X ₁ , Y ₁ ), (X ₂ , Y ₂ ), (X ₃ , Y ₃ ), and (X ₄ , Y ₄ ).

The description is made by taking as an example that the trend is the slope calculated from the positions induced by the multiple peaks. The sum Dx of the horizontal distance between each of the multiple peak sensing points and one of them (Dx=(|X ₂ -X ₁ |+|X ₃ -X ₁ |+|X ₄ -X ₁ |)=2+5 +8) is 15, and the sum of vertical distances Dy (Dy=(|Y ₂ -Y ₁ |+|Y ₃ -Y ₁ |+|Y ₄ -Y ₁ |)=1+3+5) is 9. If it is assumed that the specific value THD is 10, then the absolute difference |Dx-Dy|(|Dx-Dy|= 6) If THD is less than a certain value, it means that the slope is relatively large (the direction of the touch track is a diagonal line), so it is judged that the operation mode should be switched to the second mode.

After the operation mode is switched to the second mode, as shown in FIG. 12B , the obtained positions of multiple peak sensing points are (X' ₁ , Y' ₁ ), (X' 2 , Y' 2 ), (X' ₂ , Y' ₂ ), (X ' ₃ ,Y' ₃ ), (X' ₄ ,Y' ₄ ), (X' ₅ ,Y' ₅ ). At this time, the sum Dx of the horizontal distance between each of the multiple peak sensing points and one of them (Dx=(|X' ₂ -X' ₁ |+|X' ₃ -X' ₁ |+|X' ₄ - X' ₁ |+|X' ₅ -X' ₁ |)=2+3+5+8) is 18, and the vertical distance sum Dy of each of a plurality of peak sensing points and one of them (Dy=( |Y' ₂ -Y' ₁ |+|Y' ₃ -Y' ₁ |+|Y' ₄ -Y' ₁ |+|Y' ₅ -Y' ₁ |)＝1+2+3+5) is 11. If it is assumed that the specific value THD is 10, the absolute difference |Dx-Dy|(|Dx-Dy|=7 ) is less than a specific value THD, it means that the slope is relatively large (the trend of the control track is a diagonal line). Therefore, the touch sensor maintains the operation mode in the second mode.

In addition, it is described by taking the determination of the sensing values of a plurality of sensing points adjacent to each of the plurality of peak sensing points as an example. In Fig. 12A, the sensing value of the sensing point on the right of the peak sensing point at position (X ₁ , Y ₁ ) (the sensing value is 26, in hexadecimal notation) is smaller than the peak sensing point at position (X ₁ , Y ₁ ) One of the sensing values of the sensing points in the upper right corner and lower right corner of the point (the sensing values are b0 and 0, respectively). _The sensing amount (the sensing amount is 11) of the right sensing point of the peak sensing point at position (X 2 , Y 2 ₎ is less than or equal to the sensing at the upper right corner and lower right corner of the peak sensing point at position (X ₂ , Y ₂ ) One of the sensing values of the point (the sensing values are b7 and 0 respectively). The sensing amount (7c) of the right sensing point of the peak sensing point at position (X ₃ , Y ₃ ) is greater than that of the sensing point at the upper right corner and lower right corner of the peak sensing point at position (X ₃ , Y ₃ ) Inductive value (inductive value is 34 and 0 respectively). The sensing amount (sensing amount b1) of the right sensing point of the peak sensing point at (X 4 , Y ₄ ) is greater than that of the sensing points at the upper right corner and lower right corner of the peak sensing point at (X ₄ , _{Y 4} ) Inductive quantities (inductive quantities are 1f and _1a respectively).

If the rule adopted is: if the sensing amount of the sensing point on the right of any one of the plurality of peak sensing points is smaller than the sensing amount of the sensing point in the lower right corner or upper right corner of the peak sensing point, then the touch track is judged and if the sensing values of the sensing points on the right side of all the peak sensing points are greater than or equal to the sensing values of the sensing points in the lower right corner or upper right corner of the peak sensing points, then the touch track is judged The direction is horizontal or vertical. Therefore, in the above situation, the touch sensor determines that the operation mode should be switched to the second mode.

After the operation mode is switched to the second mode, as shown in FIG. 12B , the obtained positions of multiple peak sensing points are (X' ₁ , Y' ₁ ), (X' 2 , Y' 2 ), (X' ₂ , Y' ₂ ), (X ' ₃ ,Y' ₃ ), (X' ₄ ,Y' ₄ ), (X' ₅ ,Y' ₅ ). At this time, the sensing value of the sensing point on the right of the peak sensing point at position (X' ₁ , Y' ₁ ) (the sensing value is 26, in hexadecimal notation) is less than or equal to the position at (X' ₁ , Y' ₁ ) is one of the sensing values of the sensing points at the upper right corner and the lower right corner of the peak sensing point (the sensing values are b0 and 0, respectively). The sensing value (the sensing value is 11) of the sensing point on the right of the peak sensing point at position (X' 2 , Y' ₂ ) is _less than or equal to the upper right corner of the peak sensing point at position (X' ₂ , Y' ₂ ) and One of the sensing values of the sensing point in the lower right corner (the sensing values are b7 and 0, respectively). The sensing amount (a7) of the right sensing point of the peak sensing point at position (X' 3 , Y' ₃ ) is greater than the upper right corner and lower right corner of the peak sensing point at position (X _{' 3} , Y' ₃ ) The sensing amount of the sensing point (the sensing amount is 58 and 0 respectively). The sensing amount (7c) of the right sensing point of the peak sensing point at (X' ₄ , Y' ₄ ) is greater than the upper right corner and lower right corner of the peak sensing point at (X' ₄ , Y' ₄ ) The sensing amount of the sensing point (the sensing amount is 34 and 0 respectively). The sensing amount (sensing amount b1) of the right sensing point of the peak sensing point at (X' ₅ , Y' ₅ ) is greater than the upper right corner and lower right corner of the peak sensing point at (X' ₅ , Y' ₅ ) The sensing amount of the sensing point (the sensing amounts are 1f and 1a respectively).

If the rule adopted is: if the sensing amount of the sensing point on the right of any one of the plurality of peak sensing points is smaller than the sensing amount of the sensing point in the lower right corner or upper right corner of the peak sensing point, then the touch track is judged and if the sensing values of the sensing points on the right side of all the peak sensing points are greater than or equal to the sensing values of the sensing points in the lower right corner or upper right corner of the peak sensing points, then the touch track is judged The direction is horizontal or vertical. Therefore, in the above situation, the touch sensor determines that the operation mode remains the second mode.

FIG. 13A and FIG. 13B are schematic diagrams of sensing quantities of multiple sensing points in a touch device according to another embodiment of the present invention. In the embodiment of FIG. 13A , the operation mode is preset as the first mode, and the specific scanning order is scanning from top to bottom column by column and from left to right. The touch sensor uses the touch method in FIG. 10 , and the scribing test The method uses five copper pillars with a center spacing of 12, 12, 12, 12 and 24 centimeters to carry out vertical line scribing.

In FIG. 13A, the touch device uses more than two chips (that is, more than two touch sensors) to process sensing points in different areas. Therefore, multiple sensing points of the main area are stored in the storage unit. Inductive values of multiple sensing points in the slave area and the sensing values of multiple sensing points in the slave area, in which the main area not only stores the sensing values of the multiple sensing points processed by the main chip, but also configures a partial area to store the sensing values of some of the slave areas, so that The chip in the master area can successfully judge the peak sensing point, while the slave area stores the sensing values of multiple sensing points processed by the slave chip. In the embodiment of FIG. 13A , the positions of the multiple peak sensing points in the main area are (X ₁ , Y ₁ ), (X ₂ , Y ₂ ), (X ₃ , Y ₃ ), (X ₄ , Y ₄ ), and the positions of multiple peak sensing points in the slave area are (X' ₁ , Y' ₁ ), (X' ₂ , Y' ₂ ), and (X' ₃ , Y' ₃ ).

Since it is difficult to define the size of the specific value THD in some areas, the method of using the slope calculated from the positions induced by the plurality of peaks may cause the vertical lines to be merged, resulting in misjudgment. In addition, in the main area, if the angle of the diagonal line is not large, it may cause the absolute difference between the sum of horizontal distances Dx and the sum of vertical distances Dy between each of the plurality of peak sensing points and one of them. |Dx-Dy| is not less than a certain value THD, resulting in the fusion of diagonal lines, or, there is only one peak sensing point in the main area, which makes it impossible to judge the touch trajectory.

The description is made by taking as an example that the trend is the slope calculated from the positions induced by the multiple peaks. In FIG. 13A , the sum Dx of the horizontal distance between each of the multiple peak sensing points in the main area and one of them (Dx=(|X ₂ -X ₁ |+|X ₃ -X ₁ |+|X ₄ - X ₁ |)=2+3+5) is 10, and the sum of vertical distances Dy(Dy=(|Y ₂ -Y ₁ |+|Y ₃ -Y ₁ |+|Y ₄ -Y ₁ |)=0+0+0) is 0. If it is assumed that the specific value THD is 11, the absolute difference between the sum of the horizontal distance Dx and the sum of the vertical distance Dy between each of the plurality of peak sensing points in the main area and one of them |Dx-Dy|(|Dx- If Dy|=10) is less than a certain value THD, it means that the direction of the touch track is misjudged as a diagonal line, so the main chip will mistakenly switch the operation mode to the second mode.

In addition, in FIG. 13A , the sum Dx of the horizontal distance between each of the plurality of peak sensing points in the slave area and one of them (Dx=(|X' ₂ -X' ₁ |+|X' ₃ -X' ₁ |)=2+6) is 8, and the sum of vertical distances Dy(Dy=(|Y' ₂ -Y' ₁ |+|Y' ₃ -Y' ₁ |)=0+1) is 1. If it is assumed that the specific value THD is 11, then the absolute difference |Dx-Dy|(|Dx- If Dy|=7) is less than a certain value THD, it means that the direction of the touch track is misjudged as a diagonal line, so the slave chip will mistakenly switch the operation mode to the second mode.

After the operation mode is switched to the second mode, as shown in Figure 13B, the position of the peak sensing point obtained by the master area is (X'' ₁ , Y'' ₁ ), while the position of the peak sensing point obtained by the slave area is (X''' ₁ ,Y''' ₁ ), (X''' ₂ ,Y''' ₂ ). Since the number of peak sensing points in the main area is not enough, the main chip will not be able to judge the touch track. In addition, the slave chip may mistakenly judge the touch track as a diagonal line. Generally speaking, the master chip and the slave chip will not be able to smoothly obtain the touch traces marked by vertical lines.

In the case that the touch device uses more than two chips to process sensing points in different areas, preferably, the embodiment of the present invention proposes to use a plurality of sensing points that are adjacent to each of the plurality of peak sensing points The sensing quantity is used to determine whether the operation mode should be switched or maintained.

The direction is determined by taking the sensing values of multiple sensing points adjacent to each of the multiple peak sensing points as an example for illustration. As shown in Figure 13A, the sensing amount (the sensing amount is 9d, in hexadecimal) of the sensing point on the right of the peak sensing point at (X ₁ , Y ₁ ) in the main area is greater than that at (X ₁ , Y _{1 )} ) of the peak sensing point in the upper right corner and the lower right corner of the sensing point sensing value (the sensing value is 62 and 0 respectively). The sensing value (the sensing value is 91) of the right sensing point of the peak sensing point (X ₂ , Y ₂ ) in the main area is greater than that of the upper right corner and lower right corner of the peak sensing point at (X ₂ , Y ₂ ). The sensing value of the sensing point (the sensing value is 66 and 0 respectively). The sensing value (the sensing value is 86) of the right sensing point of the peak sensing point at (X ₃ , Y ₃ ) in the main area is greater than that of the upper right corner and lower right corner of the peak sensing point at (X ₃ , Y ₃ ). The sensing amount of the sensing point (the sensing amount is 60 and 0 respectively). The right, upper right corner and lower right corner of the peak sensing point at (X ₄ , Y ₄ ) in the main area do not have sensing points, so no comparison is necessary.

If the rule adopted is: if the sensing amount of the sensing point on the right of any one of the plurality of peak sensing points is smaller than the sensing amount of the sensing point in the lower right corner or upper right corner of the peak sensing point, then the touch track is judged and if the sensing values of the sensing points on the right side of all the peak sensing points are greater than or equal to the sensing values of the sensing points in the lower right corner or upper right corner of the peak sensing points, then the touch track is judged The direction is horizontal or vertical. Therefore, in the above situation, the main chip will maintain the operation mode in the first mode.

As shown in Figure 13A, the sensing value (the sensing value is 86, in hexadecimal notation) of the sensing point on the right side of the peak sensing point at the position (X' ₁ , Y' ₁ ) in the slave area is greater than that at the position (X' ₁ ,Y' ₁ ) The sensing values of the sensing points in the upper right corner and lower right corner of the peak sensing point (the sensing values are 60 and 0 respectively). The sensing value (the sensing value is 81) of the right sensing point of the peak sensing point at (X' ₂ , Y' ₂ ) in the slave area is greater than the upper right corner of the peak sensing point at (X' ₂ , Y' ₂ ) The sensing value of the sensor point in the lower right corner (the sensing value is 66 and 0 respectively). The sensing value (the sensing value is 90) of the right sensing point of the peak sensing point at position (X' ₃ , Y' ₃ ) in the slave area is greater than the upper right corner of the peak sensing point at position (X' ₃ , Y' ₃ ) The sensing value of the sensor point in the lower right corner (the sensing value is 0 and 81 respectively).

If the rule adopted is: if the sensing amount of the sensing point on the right of any one of the plurality of peak sensing points is smaller than the sensing amount of the sensing point in the lower right corner or upper right corner of the peak sensing point, then the touch track is judged and if the sensing values of the sensing points on the right side of all the peak sensing points are greater than or equal to the sensing values of the sensing points in the lower right corner or upper right corner of the peak sensing points, then the touch track is judged The direction is horizontal or vertical. Therefore, in the above situation, the slave chip will determine that the operation mode should maintain the first mode.

Then the master chip and the slave chip fuse the peak sensing points at the overlapping positions of the partial area and the slave area (that is, the peak sensing points at positions (X ₃ , Y ₃ ) and (X ₄ , Y ₄ ) in the partial area are respectively integrated with those in the slave area. position (X' ₁ , Y' ₁ ) and (X' ₂ , Y' ₂ ) peak sensing points are merged), and five peak sensing points are left after fusion (Fig. 13A does not show the fusion result), to In this way, the touch track of the vertical line is correctly determined according to the multiple peak sensing points.

The touch control method in Figure 14 includes steps S121-S125, wherein steps S121 and S122 are the same as steps S31 and S32 in Figure 3, and steps S123-S125 are the same as steps S905-S907 in Figure 10, so the same content will not be repeated . As can be seen from FIG. 14 , in the embodiment of the present invention, the step of judging whether the operation mode needs to be switched or maintained according to the direction may be combined with any of the above methods of judging the peak sensing point.
