Abstract: A transmission system includes a first touch device and a second touch device. The first touch device and the second touch device work together to operate in a touch mode or in an application mode. When the first touch device and the second touch device work together to operate in the application mode, the first touch device acquires an absolute motion trajectory or an absolute rotation angle of the second touch device, and performs an application according to the absolute motion trajectory or the absolute rotation angle.

Abstract: A transmission system includes a first touch device and a second touch device. The second touch device includes a transmission region and the transmission region forms an invisible barcode. The first touch device and the second touch device work together to operate in a touch mode or in an application mode. When the first touch device and the second touch device work together to operate in the application mode, the transmission region uses the invisible barcode to transmit a transmission signal to the first touch device to unlock the first touch device.

Abstract: A touch detection method, suitable for a touch display panel including multiple sensing pads, is disclosed. The sensing pads are divided into groups and each of the groups includes at least two columns of the sensing pads. The touch detection method includes following steps. In a first mode, the sensing pads are scanned group-by-group for detecting whether a touch event occurs on a touch identified group. In a second mode, the sensing pads are scanned column-by-column to identify a touch position of the touch event.

Abstract: A data transmission method includes: 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; if yes selecting, by the second touch device, a receiving area in a first overlap range according to signal intensity of the first sensing signal; 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; if yes, 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; determining a final transmitting area and a final receiving area; and performing a data transmission process.
