Abstract: A capacitive touch system and a sensing method thereof are disclosed. The capacitive touch system includes a touch panel; a touch control chip; and an active pen which includes a receiving part, a transmitting part, a control unit, and a pressure sensing element. The control unit controls the transmitting unit to output a pen driving signal according to a pen sensing signal. The pressure sensing element detects a pen pressure signal. The control unit outputs a voltage signal in responsive to the pen pressure signal after a time delay period. In the capacitive touch system and the sensing method thereof, the active pan is not required to be paired with the touch panel.

Abstract: A touch display system includes a touch panel; a touch control chip configured to transmit a driving signal to the touch panel; an active pen configured to transmit a signal based on the driving signal of the touch control chip, the signal including two signal segments that are called a position signal and an ID signal, the touch control chip resolving the signal transmitted by the active pen to obtain an ID data carried by the ID signal and inquiring a property of the active pen corresponding to the ID data; and a display panel configured to display traces in accordance with the property of the active pen. Similar to the usage of a traditional marker pen, such an active panel is easily to be used by a user.
