  • Calculation of touch coordinates using mixed processing of mutual capacitance sensing data and self capacitance sensing data
    Patent number: 11093097
    Abstract: A data frame in a touch capacitive sensing circuit includes both mutual capacitance data and self capacitance data. The mutual capacitance data and self capacitance data of the frame are filtered to define mutual capacitance and self capacitance islands. Centroids of the mutual capacitance and self capacitance islands are calculated and then processed in a weighted mixing operation to produce a hybrid centroid that more accurately locates the coordinates of a detected touch/hover.
    Type: Grant
    Filed: August 4, 2020
    Date of Patent: August 17, 2021
    Assignee: STMicroelectronics Asia Pacific Pte Ltd
    Inventors: Youngjin Wang, Tae-gil Kang
