| titleOfInvention | Detection method of tilt angle of electronic pen |
| abstract | A method for detecting an inclination angle of an electronic pen is provided. In the present invention, an electronic pen is positioned above a digitizer, and the digitizer includes a plurality of loop antennas. The method of detecting the tilt angle of the electronic pen includes: searching for a peak loop antenna that detects the maximum induced signal value; scanning a plurality of loop antennas in the vicinity of the peak loop antenna to obtain a signal distribution; Simulating at least two signal curves from signal values induced by the peak loop antenna and the neighboring loop antenna; calculating a rate of change between the two respective signal curves; and based on the calculated rate of change And searching the control list to obtain the tilt angle of the electronic pen. The present invention can detect and acquire the tilt angle by scanning only 5 to 7 loop antennas, and effectively increase the detection efficiency of the tilt angle of the electronic pen.
