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.
Claims3
A stylus pen comprising:
- a conductive tip contactable with a touch panel;
- a pressure sensor measuring a pressure of the conductive tip applied to the touch panel and outputting a pen pressure signal;
- a frequency signal generator generating a pressure sensing signal based on the pen pressure signal and generating a position sensing signal for sensing a position of the stylus pen;
- and
- a mixer mixing the position sensing signal and the pressure sensing signal to provide a mixing signal to the conductive tip.
