Touch panel sensing data processing method

The present invention relates to the processing of touch data, and more particularly to a method for processing sensing data at a junction of a plurality of touch areas on a touch panel.

With the advancement of process technology, electronic products with large-sized touch panels are increasingly popular. In order to avoid the increase in the size of the wafer, the thinness and thinness of the product, and the reduction in production cost, the large-sized touch panel usually performs data processing by using a plurality of wafers. In other words, the large-size touch panel is divided into a plurality of touch areas, and each touch area is processed by sensing data by a corresponding single chip.

However, in the data processing junction of two wafers corresponding to any two adjacent touch regions, the misjudgment of the touch event is often prone to occur. For example, when a user touches the intersection of two touch areas with a single finger, each sensor individually calculates a sensing coordinate, which will result in a touch object (eg, a finger; a single point) Touch) is misidentified as two touching objects (for example, two fingers; multi-touch).

Therefore, there is a need for a method of processing sensing data at the junction of a touch area to solve the above problems.

In view of the above, an object of the present invention is to provide a processing method for processing sensing data at a boundary of a plurality of touch areas on a touch panel to solve the above problems.

According to an embodiment of the invention, a method for processing sensing data of a touch panel is disclosed. The touch panel includes at least a first touch area and a second touch area adjacent to each other. The first touch area is scanned by a first control circuit and the corresponding sensing data is obtained. The second touch The control area is scanned by a second control circuit and the corresponding sensing data is obtained. The method includes the following steps: transmitting, by the second control circuit, the sensing data of a first transmission area of the second touch area to the first control circuit, where the first transmission area includes the second touch N sensing lines adjacent to the intersection of the first and second touch areas, and N is a positive integer; using the first control circuit to sense the sensing data of the first transmission area as the first control circuit a first end portion of the first and second touch area intersections; the first control circuit is used to find a first reference boundary based on the first end data; and the second control circuit is used according to at least The first transmission area is used to find a second reference boundary; and the first and second control circuits are used to determine a touch object position on the touch panel via the first and second reference boundaries, respectively.

The sensing data processing method provided by the present invention can be applied to a touch device having a plurality of wafers for judging touch information, so that the touch device not only saves the number of wafer pins, is light and thin, reduces production cost, and can also reduce production cost.

Please refer to FIG. 1 , which is a schematic diagram of an embodiment of a touch device according to the present invention. The touch device 100 can include, but is not limited to, a touch panel 110 and a control unit 120. The control unit 120 is coupled to the touch panel 110 for scanning the touch panel 110 to obtain a corresponding sense. The data is measured, and the obtained sensing data is calculated to determine touch information on the touch panel 110 (for example, the position of the touch object). In this embodiment, the touch panel 110 includes at least a plurality of touch regions 110_1 and 110_2 adjacent to each other, wherein the touch region 110_1 is connected to the touch region 110_2 in a positive direction of the X axis of the horizontal axis (ie, The touch area 110_1 is located on the left side of the touch area 110_2. The control unit 120 includes at least a plurality of control circuits 120_1 and 120_2, wherein the touch area 110_1 is scanned by the control circuit 120_1 and the corresponding sensing data SD1 is obtained, and the touch area 110_2 is scanned by the control circuit 120_2 and obtained. Corresponding sensing data SD2. In addition, the touch region 110_1 is provided with M sensing lines/wirings in the X-axis direction of the horizontal axis, and each sensing line extends along the Y-axis direction of the vertical axis, and the touch region 110_2 is in the X-axis direction of the horizontal axis. There are S sensing lines, where M and S are positive integers. Please note that for the sake of simplicity, Figure 1 only shows the sensing line in the X-axis direction of the horizontal axis. However, those skilled in the art should be able to understand that each touch area can also be provided with a sensing line in the Y-axis direction (not shown in In FIG. 1 ), the two-dimensional coordinate position of the touch object on the touch panel 110 is detected.

In order to determine the touch information around the touch area 110_1 and 110_2, the present invention performs the sensing data transmission between the touch areas 110_1 and 110_2 adjacent to each other, so that the control circuits 120_1 and 120_2 process the same. The sensing data includes sensing data located around the boundary BD, wherein the control circuits 120_1 and 120_2 each have the same sensing data near the boundary BD, and the sensing line corresponding to the same sensing data can be regarded as a data overlap. Area. Next, the control circuits 120_1 and 120_2 can refer to a reference boundary in the overlap region of the data to determine a touch object position around the border BD. In order to facilitate the understanding of the technical features of the present invention, the sensing circuit 120_2 first transmits the sensing data of the touch area 110_2 adjacent to the interface BD to the control circuit 120_1 as an implementation example of the sensing data transmission. However, this is not intended to be a limitation of the invention.

Referring to FIG. 2 to FIG. 4, first, in step 210, the control circuit 120_2 can transmit the sensing data TD1 of the transmission area TZ1 of the touch area 110_2 to the control circuit 120_1, where the transmission area TZ1 includes the touch area. N sense lines of BD adjacent to the junction in 110_2 (N is a positive integer less than S). In step 220, the control circuit 120_1 may use the sensing data TD1 of the transmission area TZ1 as the control circuit 120_1 at the end piece data ED1 adjacent to the boundary BD. In other words, in addition to scanning the M sensing lines of the touch area 110_1 to obtain the sensing data SD1, the control circuit 120_1 transmits the sensing data TD1 of the transmission area TZ1 as the end data ED1, which is equivalent to the control circuit 120_1. The N sense lines of the touch area 110_2 are also scanned to obtain the end data ED1. Therefore, one of the data areas DR1 processed by the control circuit 120_1 includes the sensing data SD1 and the end data of the M sensing lines in the touch area 110_1. ED1 (corresponds to the sensing data of N sensing lines). One of the data areas DR2 processed by the control circuit 120_2 is the sensing data SD2 including the S sensing lines in the touch area 110_2.

As can be seen from the above, the control circuit 120_1 is equivalent to scanning the (M+N) sense line in the X-axis direction of the horizontal axis (ie, the data area DR1), and the control circuit 120_2 is scanning the S-axis on the horizontal axis of the X-axis. Induction line (ie data area DR2). In other words, the control circuit 120_1 and the control circuit 120_2 both scan the N sensing lines adjacent to the boundary BD in the touch area 110_2 and obtain the corresponding sensing data. Therefore, the N sensing lines can be regarded as a data overlapping area (ie, the transmission area TZ1) on the touch panel 110 shown in FIG. 1. Next, the control circuit 120_1 and the control circuit 120_2 can determine the position of the touch object on the touch regions 110_1 and 110_2 according to a reference boundary RB in the overlap region of the data.

It should be noted that, although the end data ED1 and the sensing data TD1 correspond to the sensing data of the N sensing lines adjacent to the boundary BD in the touch area 110_2, the end data ED1 is corresponding to the sensing area DR1. The line position and the sensing data TD1 are different in the sensing line position corresponding to the data area DR2. For example, in the case where each control circuit uses the lower left corner in the corresponding data area as the coordinate reference origin (for example, the reference origin O1 (0, 0) of the touch area 110_1, and the touch area 110_2 The reference origin O2 (0, 0)), the control circuit 120_1 uses the end data ED1 (sensing data of N sensing lines) as the sensing of the (M+1)~(M+N) sensing lines For the data, the control circuit 120_2 uses the sensing data TD1 of the transmission area TZ1 as the sensing data of the first to N sensing lines. That is to say, the sensing data corresponding to the same sensing line among the end data ED1 and the sensing data TD1 corresponds to different sensing line positions, and the same sensing line in the data overlapping area (transmission area TZ1) Corresponding to different sensing line positions in different data areas.

Therefore, after the control circuit 120_1 finds a reference boundary M1 according to at least the end data ED1, and the control circuit 120_2 finds a reference boundary M2 according to at least the transmission area TZ1 (as shown in step 230), the control circuit 120_1 and the control The circuit 120_2 can determine the position of the touch object on the touch panel 110 shown in FIG. 1 via the reference boundary M1 and the reference boundary M2, respectively, as shown in step 240, wherein the reference boundary M1 corresponds to the reference boundary M2. Reference boundary RB in the overlap region of the data. In this embodiment, since the reference boundary RB can equally divide the data overlap region (ie, the line in the overlap region of the data), the reference boundary M1 and the reference boundary M2 The transfer zone TZ1 can be equally divided in the X-axis direction of the horizontal axis. A further description of the steps (steps 230 and 240) of determining the position of the touch object on the touch panel according to the reference boundary is as follows.

Please refer to FIG. 4 and FIG. 5 to FIG. 9. In step 532, the control circuit 120_1 (eg, the first control circuit) can calculate the reference boundary M1 (eg, the first reference boundary) in the control circuit 120_1. A reference position R _M1 (eg, a first reference position) in the processed data area DR1 (eg, the first data area), and a control circuit 120_2 (eg, a second control circuit) may calculate a reference boundary M2 (eg, The second reference boundary is a reference position R _M2 (eg, a second reference position) among the data areas DR2 processed by the control circuit 120_2. In the embodiment shown in FIG. 4, since the control circuit 120_1 uses the lower left corner in the data area DR1 as the coordinate reference origin O1 (0, 0), the control circuit 120_1 can determine the number of sensing lines corresponding to the data area DR1. The reference position R _M1 is calculated by the difference between (M + N) and half of the number N of sensing lines of the transmission area TZ1. More specifically, the reference position R _M1 can be expressed as: R _M1 = (cTNoX - 1) × OSR - ((cPartial_XTraceNum - 1) × OSR / 2)

Where cTNoX is the number of sensing lines (M+N) of the data area DR1, OSR is the number of interpolation points of the sensing line converted into X-axis coordinates, and cPartial_XTraceNum is the data overlapping area (in this embodiment, the transmission area TZ1) ) The number of sensing lines. Similarly, since the control circuit 120_2 takes the lower left corner in the data area DR2 as the coordinate reference origin O2 (0, 0), the control circuit 120_2 can calculate the reference position R _M2 according to the half of the number N of sensing lines of the transmission area TZ1. :R _M2 =(cPartial_XTraceNum-1)×OSR/2

Next, the control circuit 120_1 and the control circuit 120_2 can determine the position of the touch object on the touch panel (the plurality of touch regions 110_1 and 110_2) according to the reference position R _M1 and the reference position R _M2 . In step 542, the control circuit 120_1 can calculate the sensing data possessed by the data area DR1 to obtain a sensing position X _M (corresponding to the sensing point C _M (X _M , Y _M )) (eg, the first sensing) Position), and calculating the sensing data possessed by the data area DR2 to obtain a sensing position X _S (corresponding to the sensing point C _S (X _S , Y _S )) (eg, the second sensing position). In step 544, the control circuit 120_1 can compare the sensing position X _M with the reference position R _M1 to obtain a first comparison result, and the control circuit 120_2 can compare the sensing position X _S with the reference position R _M2 to obtain a The second comparison result, and the control circuit 120_1 and the control circuit 120_2 can determine the position of the touch object according to the first comparison result and the second comparison result. In the implementation example shown in FIG. 6, the sensing position X _M is located to the left of the reference position R _M1 (ie, the sensing position X _{M is} smaller than the reference position R _M1 ), and the sensing position X _S is located at the reference position R The left side of _M2 (that is, the sensing position X _{S is} smaller than the reference position R _M2 ) (judgment criterion (1): the sensing position X _M is located in the left side region of the reference boundary M1 shown in FIG. 4, and the sensing position The X _S is located in the left side region of the reference boundary M2 shown in FIG. 4 . Therefore, the control unit 120 shown in FIG. 1 reports that the touch object position corresponds to the sensing position in the X-axis direction of the horizontal axis. X _M (as shown in step 552). For example, in the case where the control circuit 120_1 functions as a master control circuit and the control circuit 120_2 as a slave control circuit, the control circuit 120_2 can transmit the coordinate information of the data area DR2 to the control. The circuit 120_1 is configured to allow the control circuit 120_1 to integrate the coordinate information of the touch area 110_1 and the touch area 110_2. The control circuit 120_1 may further report the sensing position X _M as the position of the touch object in the X-axis direction of the horizontal axis.

In the implementation example shown in FIG. 7, when the sensing position X _M is located to the right of the reference position R _M1 and the sensing position X _S is located to the right of the reference position R _M2 (ie, the sensing position X _{M is} greater than Reference position R _M1 and the sensing position X _{S is} greater than the reference position R _M2 ) (Judgement criterion (2): the sensing position X _M is equal to the reference position R _M1 or is located in the right side region of the reference boundary M1 shown in FIG. 4, And the sensing position X _S is equal to the reference position R _M2 or the right side region of the reference boundary M2 shown in FIG. 4 , and the control unit 120 shown in FIG. 1 reports that the touch object position corresponds to the sensing Position X _S (as shown in step 554). For example, in the case that the control circuit 120_1 functions as a master control circuit and the control circuit 120_2 as a slave control circuit, the control circuit 120_2 can transmit the coordinate information of the data area DR2 to the control circuit 120_1 for integration by the control circuit 120_1. The coordinate information of the touch area 110_1 and the touch area 110_2, the control circuit 120_1 can add an offset to the sensing position X _S (for example, subtracting the number of sensing lines of the data area DR1 from the data overlapping area) The number of sensing lines is multiplied by the number of interpolation points of the X-axis coordinates converted by the sensing line; (cTNoX- cPartial_XTraceNum) × OSR) to convert it into the coordinate system corresponding to the reference origin O1 (0, 0) The coordinate position, and then the converted coordinate position is reported as the touch object position.

In the implementation example shown in FIG. 8, when the sensing position X _M is located to the right of the reference position R _M1 and the sensing position X _S is located to the left of the reference position R _M2 (ie, the sensing position X _M Greater than the reference position R _M1 and the sensing position X _{S is} smaller than the reference position R _M2 ) (Judgement criterion (3): the sensing position X _M is equal to the reference position R _M1 or is located in the right side region of the reference boundary M1 shown in FIG. 4 And the sensing position X _S is located in the left side region of the reference boundary M2 shown in FIG. 4), which means that the control circuits 120_1 and 120_2 determine the position of the touch object according to the reference boundary M1 and the reference boundary M2, respectively. For the control circuit 120_1, the touch object is not located in the touch area 110_1, and the touch object is not located in the touch area 110_2 for the control circuit 120_2. Therefore, the control circuit 120_1 can move the reference position R _M1 by a predetermined displacement from the touch area 110_1 toward the touch area 110_2, and the control circuit 120_2 can use the reference position R _M2 from the touch area 110_2 toward the touch area 110_1. the predetermined direction of movement between the shift (as shown in step 556), which is greater than the predetermined displacement between the sensing position and the reference position X _M D _M R _M1 difference between the sensed position and the reference position X _S R _M2 of the two smaller difference D _S of the difference (i.e., difference value D _S). Next, the control unit 120 shown in FIG. 1 can report that the touch object position corresponds to the sensing position corresponding to the smaller difference among the sensing position X _M and the sensing position X _S ( eg, Step 566 is shown). For example, the reference position R _M1 and the reference position R _{M2 may be} respectively moved to the reference position R _M1 ′ and the reference position R _M2 ′ such that the sensing position X _{M is} greater than the reference position R _M1 ′ and the sensing position X _{S is} greater than the reference The position R _M2 ', the control unit 120 shown in FIG. 1 can report that the position of the touch object in the X-axis direction of the horizontal axis corresponds to the sensing position X _S .

In the implementation example shown in FIG. 9, when the sensing position X _M is located to the left of the reference position R _M1 and the sensing position X _{S is} not located to the right of the reference position R _M2 (ie, the sensing position X _M Less than the reference position R _M1 and the sensing position X _{S is} larger than the reference position R _M2 ) (Judgement criterion (4): the sensing position X _M is located in the left side region of the reference boundary M1 shown in FIG. 4, and the sensing position X _S is equal to the reference position R _M2 or in the right side region of the reference boundary M2 shown in FIG. 4, which means that the control circuits 120_1 and 120_2 determine the position of the touch object according to the reference boundary M1 and the reference boundary M2, respectively. The touch object is located in the touch area 110_1 for the control circuit 120_1, and the touch object is also located in the touch area 110_2 for the control circuit 120_2. In order to determine whether the touch object position is a single touch point (ie, the sensing point C _M or the sensing point C _S ) or multiple touch points (ie, the sensing point C _M and the sensing point C _S ), The control circuit 120_1 and the control circuit 120_2 (the main control circuit) can determine the sensing position X _M among the data areas processed by the main control circuit after receiving the sensing data of the other control circuit (from the control circuit). Whether the distance difference dX between the sensing position X _S is less than or equal to a predetermined distance, and determining whether the distance difference dY between the sensing position Y _M and the sensing position Y _S is less than or equal to the predetermined distance (step 558) As shown, wherein the predetermined distance can be set to be greater than a specific multiple of the predetermined displacement, or can be set according to design requirements. For example, in the case that the control circuit 120_1 functions as a master control circuit and the control circuit 120_2 as a slave control circuit, the control circuit 120_2 can transmit the coordinate information of the data area DR2 to the control circuit 120_1, and the control circuit 120_1 can sense The measurement position X _{S is} added with an offset to convert it to the sensing position X _S ' (for example, X _S +(cTNoX-cPartial_XTraceNum) × OSR). Therefore, the distance difference dX between the sensing position X _M and the sensing position X _S ' in the data area DR1 can be expressed as "|X _S + (cTNoX-cPartial_XTraceNum) × OSR-X _M |", and the distance difference dY can be expressed as "|Y _S -Y _M |". Next, the control circuit 120_1 can determine the touch object position by the calculated distance difference dX and the distance difference dY.

When the control circuit 120_1 determines that the distance difference dX is less than or equal to the predetermined distance, and the distance difference dY is less than or equal to the predetermined distance, it means that the sensing point C _M and the sensing point C _{S can} be regarded as a single touch point. Therefore, the control circuit 120_1 can calculate a midpoint position of the sensing point C _M and the sensing point C _S in the data area DR1 ((X _M +X _S ')/2, (Y _M +Y _S )/ 2) The control circuit 120_1 can report that the touch object position corresponds to the midpoint position (as shown in step 568).

In addition, when the control circuit 120_1 determines that the distance difference dX is greater than the predetermined distance or the distance difference dY is greater than the predetermined distance, it means that the sensing point C _M and the sensing point C _{S can} be two independent touch points. position (X _M, Y _M) Thus, the control circuit 120_1 of the two touch object may return a position corresponding to the sense lines point to the position C _M C _S of the sensing points _{(X S ', Y S)} ( also That is, the touch object position described above includes the positions of the two touch objects (as shown in step 569).

Although the above-described implementation examples are described by adjacent touch regions in the X-axis of the horizontal axis, the skilled artisan should be able to easily understand after reading the descriptions of FIGS. 1 to 9. The method provided by the present invention can also be applied to a touch panel having touch regions adjacent to each other in the Y direction of the vertical axis. In addition, the method provided by the present invention can be applied to control circuits of three or more adjacent touch areas to determine touch information on the touch panel. Please refer to Figure 10 and Figure 11. FIG. 10 is a schematic diagram showing an example of the implementation of the control unit 120 (including a plurality of control circuits 120_1 120 120_3) shown in FIG. And Fig. 11 is a schematic diagram of the data areas DR1 to DR3 of the plurality of control circuits 120_1 to 120_3 shown in Fig. 10. In this embodiment, the touch panel 110 further includes a touch area 110_3, wherein the touch area 110_2 and the touch area 110_3 are respectively located on two sides of the touch area 110_1, and the touch area 110_1 is negative toward the X axis of the horizontal axis. The direction is connected to the touch area 110_3 (that is, the touch area 110_1 is located on the right side of the touch area 110_2), and the touch area 110_3 is scanned by the control circuit 120_3 and the corresponding sensing data SD3 is obtained. In addition, the touch region 110_3 is provided with T sensing lines in the X-axis direction of the horizontal axis, where T is a positive integer.

The control circuit 120_1 (main control circuit) and the control circuit 120_3 (slave control circuit) may be used in addition to the control circuit 120_1 and the control circuit 120_2 using the method shown in FIG. 2 for sensing data transmission and touch information determination. The above operation is carried out by the method shown in Fig. 2. In other words, the control circuit 120_3 can transmit the sensing data of a transmission area TZ2 of the touch area 110_3 to the control circuit 120_1, wherein the transmission area TZ2 includes the AD of the touch area 110_3 adjacent to the touch area 110_1 and the touch area 110_3. N sensing lines. Next, the control circuit 120_1 can use the sensing data TD2 of the transmission area TZ2 as the end piece data ED2 of the control circuit 120_1 adjacent to the boundary AD. That is, the control circuit 120_1 further receives the sensing data TD2 of the transmission area TZ2, which is equivalent to the control circuit 120_1 also scanning the N senses of the touch area 110_3. The end data ED2 is obtained by the line. Therefore, the data area DR1 processed by the control circuit 120_1 includes the sensing data SD1, the end data ED1, and the end data ED2 of the M sensing lines in the touch area 110_1 (corresponding to 2N). Sensing data of the sensing line). One of the data areas DR3 processed by the control circuit 120_3 is the sensing data SD3 including the T sensing lines in the touch area 110_3. In other words, the control circuits 120_1 and 120_3 each have the same sensing data near the N sensing lines at the interface AD, and the sensing lines corresponding to the same sensing data can be regarded as a data overlapping area (ie, the transmission area TZ2).

Similarly, after the control circuit 120_1 finds a reference boundary M3 according to at least the end data ED2, and the control circuit 120_3 finds at least a reference boundary M4 according to the transmission area TZ2 (as shown in step 230 of FIG. 2), The control circuit 120_1 and the control circuit 120_3 can determine the position of the touch object on the touch panel 110 shown in FIG. 1 via the reference boundary M3 and the reference boundary M4, respectively, wherein the reference boundary M3 and the reference boundary M4 both correspond to the The reference boundary RA among the data overlap areas (transmission area TZ2). As described above, the control circuit 120_1 may calculate the reference position of the reference data R & lt _M1 M1 boundary region DR1 in the control circuit of the processed 120_1, 120_2 and the control circuit may calculate the reference material in the boundary region DR2 M2 to the control circuit 120_2 processed Reference position R _M2 . In addition, the control circuit 120_1 can calculate the reference boundary M3 at a reference position R _M3 in the data area DR1 processed by the control circuit 120_1, and the control circuit 120_3 can calculate the reference boundary M4 in the data area DR3 processed by the control circuit 120_3. One of the reference positions R _M4 . The calculation of the plurality of reference positions R _M1 to R _M4 is as follows.

In the embodiment shown in FIG. 11, the control circuit 120_1 uses the lower left corner in the data area DR1 as the coordinate reference origin O1 (0, 0).
