In some embodiments, the touch device further includes a processor 120, and the processor 120 is electrically coupled to the plurality of touch units 110A-110F. Please also refer to Figure 2. FIG. 2 is a schematic diagram of a touch device 200 according to some embodiments of the present invention. The touch device 200 is the same as the touch device 100 in FIG. 1. For convenience of description and understanding, the touch device 200 only illustrates a part of the area of the touch device 200. As shown in FIG. 2, the touch device 200 includes a plurality of touch units 110B-110F. The plurality of touch units 110B-110F are arranged in the X direction and the Y direction. The X and Y directions are perpendicular to each other.

As shown in FIG. 2, the second sub-touch unit 114D includes a first touch region 114D1 and a second touch region 114D2. When the touch device 200 detects the touch range 210 on the touch device 200, the multiple touch units 110A-110F respectively return the touch area to the processor 120. The processor 120 respectively assigns a value to the plurality of first sub-touch units and the plurality of second sub-touch units. In some embodiments, the processor 120 returns a plurality of first sub-touch units and a plurality of second sub-touch units to the touch area of the processor 120 according to the multiple touch units 110A-110F respectively. Value. Further, the processor 120 respectively returns a plurality of first sub-touch units and a plurality of touch-control areas according to the touch areas of the processor 120 that are returned to the processor 120 respectively. The second sub-touch unit has a value.

For example, see Figure 2. The touch range 210 includes a part of the second sub-touch unit 114B, a part of the first sub-touch unit 112B, a part of the second sub-touch unit 114D, and a part of the second sub-touch unit 114E. Part and part of the first sub-touch unit 112E. In some embodiments, the processor 120 assigns a value to each of the sub-touch units according to the ratio of the area of each of the sub-touch units to the area of the touch range 210 relative to the area of the touch range 210. For example, in the case of the touch range 210 as shown in FIG. 2, the value given to the second sub-touch unit 114B by the processor 120 is 181, and the value given to the first sub-touch unit 112B is 181, The value given to the second sub-touch unit 114D is 1000, the value given to the second sub-touch unit 114E is 181, the value given to the first sub-touch unit 112E is 181, and the value given to the first sub-touch unit 112D is 0. The value given to the first sub-touch unit 112F is 0. In short, the processor 120 gives a corresponding value according to the area touched by each sub-touch unit. If the sub-touch unit is not touched, for example, the first sub-touch unit 112D is not touched, it represents the first sub-touch unit. The touch area of the touch unit 112D is 0. At this time, the processor 120 correspondingly gives the first sub-touch unit 112D a value of 0, and the remaining sub-touch units that have been touched are processed by the processor 120 according to the touch. The area is given a value accordingly to facilitate subsequent calculation of touch coordinates.

The processor 120 calculates the respective weight values of the two touch areas in the second sub-touch unit according to the values of the first and second sub-touch units adjacent to the second sub-touch unit. . For example, in the case of the touch range 210 as shown in FIG. 2, the processor 120 respectively assigns a number of values to the plurality of first sub-touch units and the plurality of second sub-touch units. Then, the processor 120 calculates respective weight values of the first touch area 114D1 and the second touch area 114D2 according to the values of the first sub touch units and the second sub touch units.

In some embodiments, the calculation of the weight value is performed by summing the values of the first sub-touch unit and the second sub-touch unit adjacent to the first touch area to calculate the first value. The values of the first sub-touch unit and the second sub-touch unit adjacent to the control area are added up to calculate a second value, and the first value and the second value are added up to calculate a total value, and the first value is relative to the total value. The ratio of the values calculates the weight value of the first touch area, and calculates the weight of the second touch area according to the ratio of the first value to the total value.

In some embodiments, the formulas for calculating the weight value of the first touch area and the weight value of the second touch area are as follows: Formula 1: S1 = ( N 1 / ( N 1+ N 2)); 2: S2 = ( N 2 / ( N 1+ N 2)); In the above formula, S1 represents the first weight value of the first touch area, S2 represents the second weight value of the second touch area, and N1 represents Sum the values of the first sub-touch unit and the second sub-touch unit adjacent to the first touch area to calculate the first value. N2 represents the first sub-touch area adjacent to the second touch area. The values of the touch unit and the second sub-touch unit are added together to calculate the second value. N1 + N2 represents the total value.

For example, in the case of the touch range 210 shown in FIG. 2, the first sub touch unit and the second sub touch unit adjacent to the first touch area 114D1 are the second sub touch. The unit 114B, the first sub-touch unit 112D, and the second sub-touch unit 114E, and the second touch area 114D2 The adjacent first and second sub-touch units are the first sub-touch unit 112B, the first sub-touch unit 112F, and the first sub-touch unit 112E. By summing up the values of the first sub-touch unit and the second sub-touch unit adjacent to the first touch area 114D1, the first value can be calculated as 181 + 0 + 181 = 362. By adding up the values of the first sub-touch unit and the second sub-touch unit adjacent to the second touch area 114D2, the second value can be calculated as 181 + 0 + 181 = 362. That is, through the above calculation, the first value N1 in Expression 1 and Expression 2 is 362, and the second value N2 is 362.

After calculating the first value and the second value, the processor 120 adds up the first value and the second value to calculate a total value. For example, when the first value is 362 and the second value is 362, the calculated total value is 724. That is, the total value N1 + N2 in Expression 1 and Expression 2 is 724.

Next, the processor 120 calculates a first weight value of the first touch area 114D1 according to a ratio of the first value to the total value, and then calculates a second touch area 114D2 according to the ratio of the first value to the total value. The second weight value is 0.5. That is, the calculated first value N1 and the second value N2 are brought into the above-mentioned formula 1 and formula 2, and the first weight value S1 of the first touch area can be calculated as 0.5, and the second touch value The second weight value S2 of the control area is 0.5.

In some embodiments, the processor 120 further calculates respective values of the first touch area and the second touch area according to the first weight value and the second weight value.

In some embodiments, the calculation formulas of the values of the first touch area and the values of the second touch area are as follows: Formula 3: V1 = S1 × Diff; Formula 4: V2 = S2 × Diff; In the above formula, S1 represents the first weight value of the first touch area, and S2 represents the second weight value of the second touch area , V1 represents the value of the first touch area, V2 represents the value of the second touch area, and Diff represents the value of the sub-touch unit.

For example, if the processor 120 calculates that the first weight value of the first touch area 114D1 is 0.5 and the second weight value of the second touch area 114D2 is 0.5, since the value of the sub touch unit 114D is 1000, The processor 120 calculates the value of the first touch area according to the first weight value and the second weight value to be 1000 × 0.5 = 500, and the value of the second touch area is 1000 × 0.5 = 500. That is, when the value of the sub-touch unit Diff is 1000, the value of the first weight value S1 is 0.5, and the value of the second weight value S2 is 0.5, bringing the above values into Equation 3 and Equation 4 can be obtained The value V1 of the first touch area 114D1 is 1000 × 0.5 = 500, and the value V2 of the second touch area 114D2 is 1000 × 0.5 = 500.

After calculating the first weight value of the first touch area 114D1 and the second weight value of the second touch area 114D2, the processor 120 calculates the first touch area, the second touch area, and the first sub-touch unit. The respective values are used to calculate the touch coordinates. For example, in the case of the touch range 210 shown in FIG. 2, since the value of the first touch area 114D1 and the value of the second touch area 114D2 are equal, the processor 120 calculates the touch coordinates at The X direction is located in the middle of the first touch area 114D1 and the second touch area 114D2. Since the value of the second sub-touch unit 114B is 181, the first touch The value of the control area 114D1 is 500 and the value of the second sub-touch unit 114E is 181. The processor 120 calculates that the touch coordinates are located in the middle of the second sub-touch unit 114D in the Y direction. It should be noted that, since the positions of the sub-touch units in the ranks of the touch unit array 105 are known, after the processor 120 calculates the relative positions of the touches in the multiple sub-touch units, the known The row and column positions are used to calculate the exact position of the touch.
