  • STYLUS PEN
    Publication number: 20200050315
    Abstract: A touch system includes a touch panel, a stylus pen and a touch sensing controller. The touch panel includes a plurality of driving electrodes and a plurality of sensing electrodes. The stylus pen provides the touch panel with a pen frequency signal set for detecting a position of a stylus pen and a pressure of the stylus pen. The touch sensing controller outputs a plurality of driving signals having different frequency components to the touch panel and determines at least one of touch coordinates of a finger and touch coordinates of the stylus pen based on a plurality of sensing signals received from the touch panel.
    Type: Application
