Abstract: An electronic device is provided. The electronic device includes multiple transducer pixels. Each of the transducer pixels includes a sonic transducer, a demultiplexer electrically connected to the sonic transducer, a driving line electrically connected to the sonic transducer, a switching line electrically connected to the demultiplexer, and a reading line electrically connected to the demultiplexer. The driving line is used to provide a driving signal to the sonic transducer to emit sonic waves. The switching line is used to turn on the demultiplexer to output the sensing signal received by the sonic transducer to the reading line.
