Abstract: Signal transmitting device, signal receiving device, signal transceiver device and signal transmission method use a conductive case as a transmission line to transmit/receive a modulated control signal or a sensing signal. The signal transmitting device, the signal receiving device and the signal transceiver device adopt a capacitive coupling unit as a media to transmit/receive the modulated signal, which makes the conductive case as a carrier when coupling the modulated signal onto the conductive case. When the signal is carried on the conductive case, the modulated signal is able to be captured and well transmitted.

Abstract: A window for use in an electronic device is provided. The window includes a display section and a strengthening layer. The display section is made of polyethylene terephthalate and overlaps with the strengthening layer. The strengthening layer is made of polymethyl methacrylate. The window is adhered to the electronic device with a transparent cyanoacrylate adhesive.
