1. A data transmission method for a first touch device and a second touch device, wherein the data transmission method comprises:
transmitting a plurality of first transmitting signals from a plurality of transmitting areas of the first touch device;
determining, by the second touch device, whether a first sensing signal corresponding to the plurality of first transmitting signals is received;
selecting, by the second touch device, a receiving area in a first overlap range according to signal intensity of the first sensing signal when the first sensing signal corresponding to the plurality of first transmitting signals is received;
transmitting a second transmitting signal from the receiving area;
determining, by the first touch device, whether a second sensing signal corresponding to the second transmitting signal is received;
selecting, by the first touch device, a first transmitting area in a second overlap range from the plurality of transmitting areas according to signal intensity of the second sensing signal when the second sensing signal corresponding to the second transmitting signal is received;
determining, by the first touch device, the first transmitting area to be a final transmitting area and determining, by the second touch device, the receiving area to be a final receiving area; and
performing, by the final transmitting area and the final receiving area, a data transmission process between the first touch device and the second touch device,
wherein a number of electrodes in each of the plurality of transmitting areas is greater than a number of electrodes in the receiving area.
