  • Active stylus signal identification method applied to capacitive touch panel
    Patent number: 10514782
    Abstract: An active stylus signal identification method applied to a capacitive touch panel is disclosed. When an active stylus and a finger approach the capacitive touch panel at the same time, the active stylus signal identification method includes steps of: (a) during a first period, the active stylus emits an active stylus signal toward the capacitive touch panel according to a protocol; (b) during a second period after the first period, the active stylus stops emitting the active stylus signal and a touch sensing circuit performs a finger touch sensing on the capacitive touch panel; (c) during a third period after the second period, the active stylus emits the active stylus signal toward the capacitive touch panel again according to the protocol.
