PORTABLE ELECTRONIC DEVICE AND METHOD OF CONTROL

摘要

PURPOSE: A portable electronic device and a control method thereof are provided to easily provide tactile feedback from piezoelectric actuators to a touch sensing display by easily concentrating power about touch sensing display on force sensors through a pad. CONSTITUTION: In case the piezoelectric element is shrinked according to the external force about the accumulation of the electric charge or the touch sensing display in a piezoelectric device(402), the substrate(404) bends. A pad(408) is arranged between a piezoelectric actuator and touch sensing display. In case the touch sensing display is pressed, a force sensor generates a force signal. The pads transfers the power between the touch sensing display and piezoelectric actuators.
