Electronic device including a transducer electrically connected to a demultiplexer and method for fabricating the transducer in the electronic device

An electronic device, comprising:

• a plurality of transducer pixels, each transducer pixel comprises:
• a sonic transducer;
• a first demultiplexer electrically connected to the sonic transducer;
• a driving line electrically connected to the sonic transducer;
• a switching line electrically connected to the first demultiplexer;
• a reading line electrically connected to the first demultiplexer,
• wherein the driving line is used to provide a driving signal to the sonic transducer to emit sonic waves, and the switching line is used to turn on the first demultiplexer to output a sensing signal received by the sonic transducer to the reading line;
• and
• a driving circuit electrically connected to a second demultiplexer, wherein the second demultiplexer comprises at least two transistors having source electrodes used to receive a driving signal and a reference signal respectively.
