Title:
STYLUS PEN, TOUCH-SENSING SYSTEM, TOUCH-SENSING CONTROLLER, AND TOUCH-SENSING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/034496
Kind Code:
A1
Abstract:
A stylus pen, a touch-sensing system having same, a touch-sensing controller employed therein, and a touch-sensing method using same are disclosed. The stylus pen comprises: a conductive pen case made of a conductive material; a stylus tip; and a signal supply unit. The stylus tip is connected to an end of the conductive pen case. The signal supply unit provides a pen-driving signal to the stylus tip and provides a palm rejection signal to the conductive pen case. Accordingly, the palm rejection signal, which is different from the pen-driving signal applied to the stylus tip, is applied to the conductive pen case, thereby implementing a palm rejection function.
