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 capacitive touch system and a sensing method thereof are disclosed. The capacitive touch system includes a touch panel including a plurality of driving electrodes and a plurality of sensing electrodes; a touch control chip; and an external device configured to transmit data to the touch control chip. In a position detection mode, the touch control chip drives the driving electrodes, reads a sensing signal from the sensing electrodes, and determines a position of a touch according to the sensing signal. In a data receiving mode, the touch control chip receives the data transmitted by the external device after a time delay period. In the capacitive touch system and the sensing method thereof, the position detection mode and the data receiving mode can be sequentially performed by delaying the time period.

Abstract: The disclosure provides an active stylus pen and signal transmission methods for the active stylus pen and a touch panel. The stylus has a touch module, a switching module, a signal comparison module, a control module and a pressure sensing module. The stylus determines a first signal generated by a touch panel, and compares an intensity of the first signal and a reference value through a first transmission path. When the intensity of the first signal exceeds the reference value, the stylus outputs a second signal to the touch panel. After the stylus outputs the second signal to the touch panel, the stylus switches to a second transmission path from the first transmission path. The stylus outputs a header signal to the touch panel. When determining a first time sequential distribution, the stylus outputs at least one bit of a pressure signal according to a second time sequential distribution.

Abstract: A capacitive touch device and a sensing method thereof are disclosed. The capacitive touch device includes a touch panel, at least one touch detection unit and a processing unit. The touch detection unit scans the touch panel, obtains an N-bit sensed data and compresses the N-bit sensed data to an L-bit sensed data. The processing unit receives the L-bit sensed data, decompresses the L-bit sensed data to the N-bit sensed data and calculates a coordinate of a touch according to the N-bit sensed data. The present invention is capable of decreasing the time for transmitting the sensed data, the power consumption and the requirements for the memory capacity of the touch detection unit and the memory capacity of the processing unit.
