Abstract
A sensing method includes sensing a first touch source at a first time point; transferring a first sensing signal of the first touch source to a CPU at the first time point; sensing a second touch source at a second time point; transferring a second sensing signal of the second touch source to the CPU at the second time point; stopping transferring the second sensing signal at a third time point, and the second touch source is away from the touch display device at a fourth time point; and the second time point is earlier than the third time point, the third time point is earlier than the fourth time point, and the first touch source is different from the second touch source.
