Abstract
The touch driving integrated circuit (IC) drives the touch sensing electrodes of a touch panel. The touch driving IC sends an uplink signal to an active stylus on the touch panel through the touch panel. The touch driving IC receives a downlink signal from the active stylus through the touch panel. The touch driving IC decodes the downlink signal to obtain posture information about the posture of the active stylus. The touch driving IC reports the posture information of the active stylus together with position information about the position of the active stylus on the touch panel to a system processor.
