摘要

The present invention relates to the technical field of touch controls. Provided are a touch pen and signal transmission method thereof, and a touch controller and signal detection method thereof, the touch pen signal transmission method comprising: detecting whether the tip of the touch pen is bearing pressure or whether a key on the touch pen is pressed; if yes, then transmitting a first touch signal, the first touch signal being used to calculate the current coordinate position on the touch screen of the touch pen and synchronize the time sequence of the touch pen and the touch controller; encoding the value of the detected pressure born by the tip of the touch pen and/or the key value of the key on the touch pen, and transmitting a second touch signal according to the code. The present invention realizes multiple application functions of a touch pen.
