Electromagnetic touch panels and electromagnetic touch systems

An electromagnetic touch panel, comprising:

• a total-reflection light guiding plate and a side frame surrounding the total-reflection light guiding plate, the side frame comprises a first side frame, a second side frame opposite to the first side frame, a third side frame, and a fourth side frame opposite to the third side frame, the first side frame and the second side frame are respectively configured with a plurality of first infrared (IR) emitters and a plurality of first IR receivers, the third side frame and the fourth side frame are respectively configured with a plurality of second IR emitters and a plurality of second IR receivers, polarized directions of IR rays emitted from the first IR emitters and the second IR emitters are different, after being reflected by the total-reflection light guiding plate a plurality of times, the IR rays emitted from the first IR emitters and the second IR emitters are received by the first IR receivers and the second IR receivers.
