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: 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.
