Patent ID: 8766942

Claim:
An electronic device, comprising: a touch display panel; a touch controller, coupled to the touch display panel, periodically providing a touch sensing signal to the touch display panel in a touch sensing period to detect a touch operation triggered on the touch display panel; a control core, periodically switching a level of a parallax switching signal; a parallax switching barrier, disposed on the touch display panel in parallel, being controlled by the parallax switching signal to respectively barricade at least one right-eye display zone on the touch display panel in a left-eye display period, and to barricade at least one left-eye display zone on the touch display panel in a right-eye display period; and an interference shielding module, for detecting the touch sensing signal to identify a first starting point of the touch sensing signal, and providing a control signal for driving the control core to delay the switching of the parallax signal when the first starting point is detected, so as to prevent the level switching of the parallax switching signal from being triggered in the touch sensing period.
