Abstract: Provided are an electronic device and control method therefor. The electronic device may include: a first electronic component; a second electronic component electrically connected to the first electronic component via a first line, where the second electronic component receives a data signal from the first electronic component via the first line; and a third electronic component electrically connected to the first electronic component via a second line and electrically connected to the second electronic component. At least a portion of the second line is substantially parallel to at least a portion of the first line. The third electronic component is configured to compare an electrical signal received via the second line to a reference signal and determine whether an electrostatic discharge (ESD) has occurred based on the comparison result, and the second electronic component is configured to control the first electronic component based on the determination result. Hence, it is possible to accurately detect ESD occurrence by using a coupling circuit and an electrical signal coupled with an electrical signal generated by ESD.
