An electronic device includes: a touch controller, periodically providing a touch sensing signal in a touch sensing period to a touch display panel for touch detection; a control core, periodically switching a level of a parallax switching signal; a parallax switching barrier, for respectively barricading a right-eye display zone and a left-eye display zone on the touch display panel in a left-eye display period and a right-eye display period in response to the parallax display switching signal; and an interference shielding module, for delaying the level switching of the parallax switching signal of the control core when a starting point of the touch sensing signal is detected, so as to prevent the level switching of the parallax switching signal from being triggered in the touch sensing period.
