An electromagnetic touch displayer is provided. The electromagnetic touch displayer may work with an electromagnetic signal transmission apparatus. The electromagnetic touch displayer comprises a plurality of sense antennas. When the electromagnetic touch displayer enters into a sleep mode, a part of the sense antennas will keep in the work mode. If the user wants to wake the electromagnetic touch displayer up to make it into the work mode, he will make the electromagnetic signal transmission apparatus transmit an electromagnetic signal. Then, the electromagnetic touch displayer receives the electromagnetic signal via the sense antennas which are still working, and enters into the work mode according to the electromagnetic signal. |
