Abstract
The present invention discloses an energy saving type touch-controlled liquid crystal display device. The energy saving type touch-controlled liquid crystal display device has a liquid crystal panel with a touch-sensing function and a piezoelectric film. The piezoelectric film senses the pressure applied to the liquid crystal panel and generates electric power. The electric power is then stored in a battery module for relative electric components to utilize, and thereby accomplishes an object of energy saving.
