Abstract: The invention provides a touch device and a communication method thereof. The touch device includes a display panel and a controller. The controller controls the display panel to perform a display driving operation and a touch sensing operation. The controller may transmit a first wireless signal to another slave communication device via the display panel in a touch sensing period. The controller may receive a second wireless signal sent by another master communication device via the display panel in the touch sensing period. When the touch device serves as one of a master communication device and a slave communication device, a time length of the touch sensing period is a first time length. When the touch device serves as the other of the master communication device and the slave communication device, the time length of the touch sensing period is a second time length greater than the first time length.
