Energy recovery system for recovering pressure energy of touch input to touch screen panel

摘要

Embodiments provide the energy recovery system capable of converting mechanical energy of a touch input to a touch screen panel into electrical energy and storing the converted electrical energy. The energy recovery system may include a touch screen panel including a piezoelectric material, an energy recovery device recovering electrical energy generated by the piezoelectric material, and an electrical energy storage device storing the recovered electrical energy.
