The present invention provides a switching circuit and an electronic device, which relate to the field of electronic technologies, so as to improve reliability of image processing. The switching circuit includes a comparator circuit, a first switch circuit, a second switch circuit, a first drive voltage source, and a second drive voltage source. Two input ends of the comparator circuit respectively receive an input voltage and a reference voltage, an output end is separately connected to an input end of the first switch circuit and an input end of the second switch circuit; The comparator circuit determines whether the input voltage is greater than the reference voltage, outputs a high level when determining that the input voltage is greater than the reference voltage, and outputs a low level when determining that the input voltage is not greater than the reference voltage.
