The digitizer integrated circuit 430 may check the change in intensity of the magnetic field measured in the plurality of conductive patterns (eg, the plurality of conductive patterns 530-a through 530-i of FIG. 5C). As described above, the change in the intensity of the magnetic field may generate a voltage (or current) by the electromagnetic induction phenomenon. The digitizer integrated circuit 430 may check the change in intensity of the magnetic field based on the magnitude of the voltage (or current) generated by the electromagnetic induction phenomenon. The digitizer integrated circuit 430 may identify a conductive pattern having the largest change in intensity of the magnetic field among the plurality of conductive patterns 530-a to 530-i. The digitizer integrated circuit 430 may identify which conductive pattern has the largest change in the intensity of the magnetic field based on the strength of the current measured in the channels connected to the plurality of conductive patterns 530-a through 530-i. For example, the digitizer integrated circuit 430 may identify that the first coil 530-f of the plurality of conductive patterns 530-a through 530-i has the largest change in intensity of the magnetic field. Digitizer integrated circuit 430 has a predetermined number of conductive patterns (e.g., the two closest coils (e.g., closest to the conductive pattern (e.g., first coil 530-f)) that has the greatest change in intensity of the magnetic field. 530-e, 530g)) can be seen the change in the intensity of the magnetic field. The digitizer integrated circuit 430 may adjust the Y-axis coordinate corresponding to the first coil 530-f based on the difference value of the change in intensity of the magnetic field measured by the two coils 530-e and 530-g. have. To adjust the Y-axis coordinates may use Equation 1 described below.

[Equation 1]

(Px: Coordinate of loop coil where peak level is detected, DX: Array interval of loop coil arranged in X-axis direction, VL: Signal level of loop coil with highest signal level, VL, VR: Loop with highest signal level Signal level of loop coils on both sides of the coil)

Referring to the meaning of Equation 1, for example, when the change in the magnetic field strength of the second coil (530-e) is greater than the change in the magnetic field strength of the third coil (530-g), the first coil (530-) The Y-axis coordinate corresponding to f) may be adjusted to be closer to the second coil 530-e. On the contrary, when the change in the magnetic field strength of the second coil 530-e is smaller than the change in the magnetic field strength of the third coil 530-g, the Y-axis coordinate corresponding to the first coil 530-f is converted to the third. It may be adjusted to be closer to the coil 530-g.

FIG. 5D illustrates coils for measuring coordinates in a horizontal direction (X-axis) of coordinates on a display (eg, display 320 of FIG. 3) of an input device (eg, input device 400 of FIG. 3). . Referring to FIG. 5D, conductive patterns 540-a to 540-j for measuring coordinates in the vertical direction may be disposed in the digitizer 331.

The following describes the contents of the digitizer integrated circuit (eg, the digitizer integrated circuit 430 of FIG. 4) obtaining the X-axis coordinates on the display 320 of the input device 400.

The digitizer integrated circuit 430 may measure a change value of the intensity of the magnetic field measured by each of the plurality of conductive patterns 540-a through 540-j. As described above, the change in the intensity of the magnetic field may generate a voltage (or current) by the electromagnetic induction phenomenon. The digitizer integrated circuit 430 may check the change in intensity of the magnetic field based on the magnitude of the voltage (or current) generated by the electromagnetic induction phenomenon. The digitizer integrated circuit 430 may identify which conductive pattern has the largest change in the intensity of the magnetic field based on the strength of the current measured in the channels connected to the plurality of conductive patterns 540-a through 540-j. The digitizer integrated circuit 430 may identify a conductive pattern having the largest change in intensity of the magnetic field among the plurality of conductive patterns 540-a through 540-j. For example, the digitizer integrated circuit 430 may identify that the second coil 540-f has the largest change in the intensity of the magnetic field among the plurality of conductive patterns 540-a through 540-j. Digitizer integrated circuit 430 has a set number of conductive patterns (e.g., the two closest coils 540) that are close to the conductive pattern (e.g., second coil 540-f) having the largest change in the strength of the magnetic field. -e, 540g)) can be seen the change in the strength of the magnetic field. The digitizer integrated circuit 430 may adjust the X-axis coordinate corresponding to the second coil 540-f based on the difference in the intensity change of the magnetic field measured by the two conductive patterns 540-e and 540-g. have. Adjusting the X-axis coordinates may use Equation 1 described above. Using the above-described method, the digitizer integrated circuit 430 may check the position on the digitizer 331 of the input device 400 based on the difference value of the change in the intensity of the magnetic field measured in the first pattern.

6A to 6B illustrate examples of a result of determining a position of the input device 400 using a first pattern in an electronic device according to various embodiments of the present disclosure.

FIG. 6A illustrates a case in which a touch input (or proximity input) is performed in a vertical direction (Y-axis direction) by using an input device (for example, the input device 400 of FIG. 3). The figure which shows the result of tracking the coordinate detected by the position, inside and 1st area | region of 1st area | region 510 (for example, 1st area 371 of FIG. 3, 1st area 510 of FIG. 5). In the vicinity of 510, it may be confirmed that the direction of the line input by the input device 400 is not constant. For example, in the vicinity of the first region 510 and the first region 510, it may be confirmed that the error of the coordinate detected by the position of the input device 400 is large.

FIG. 6B illustrates an input device (or proximity input) when an input device (for example, the input device 400 of FIG. 3) is performed in an oblique direction (a direction that forms an angle of 45 degrees with the x-axis). The result of tracking the coordinate detected by the position of 400 shows the direction of the line input by the input device 400 in the vicinity of the 1st area | region 510 and the 1st area | region 510. You can check it. For example, in the vicinity of the first area 510 and the first area 510, it may be confirmed that an error between the coordinate detected by the position of the input device 400 and the actual coordinate is large.

The error with respect to the first region 510 is because the plurality of conductive patterns included in the first pattern 510 are designed to not include the first region 510 while being disposed outside the first region 510. Can be generated. Due to the arrangement structure described above, some of the conductive patterns (eg, conductive patterns disposed near the opening 370) of the plurality of conductive patterns change in the size of the magnetic field with respect to the partial region due to the opening 370. May not be measurable. Referring to FIG. 6C, in the conductive pattern 600 illustrated in FIG. 6C, when an opening (eg, the opening 370 of FIG. 3) does not exist, the area of the conductive pattern 600 may be A region 610 and It may be the sum of the B regions 620. However, due to the presence of the opening 370, a phenomenon in which the area of the conductive pattern 600 is slightly damaged, for example, the size change of the magnetic field corresponding to the width of the A region 610 may not be measured. When the opening 370 is present, an area of the conductive pattern 600 may correspond to an area of the B region 620. The difference in area may cause an error in coordinate recognition.
