Document Type and Number:
WIPO Patent Application WO/2024/087345
Kind Code:
A1
Abstract:
A touch area positioning method and apparatus, a terminal device, and a storage medium, relating to the field of touch. The method comprises: determining a first touch area and a second touch area according to differential signals of first sensing units and a preset touch threshold; respectively determining a second sensing unit and a third sensing unit in the first touch area and the second touch area, and respectively expanding the area where the second sensing unit is located and the area where the third sensing unit is located, to obtain a third touch area and a fourth touch area; and combining the third touch area and the fourth touch area. According to the method, a plurality of first sensing units having differential signals greater than a touch threshold or absolute values of the differential signals greater than the touch threshold can be identified, and the second sensing unit corresponding to the maximum differential signal in the first touch area and the third sensing unit corresponding to the minimum differential signal in the second touch area can be identified respectively; thus, the accuracy of touch area positioning results is improved.
