1. An energy saving type touch-controlled liquid crystal display device, characterized in that:

  • the energy saving type touch-controlled liquid crystal display device comprises;

    a liquid crystal panel having a touch-controlled assembly mounted therein to provide a touch-sensing surface in a display area thereof, and the liquid crystal panel comprises a color filter substrate and a thin-film transistor array substrate;

    a protection layer mounted on a top of the liquid crystal panel;

    a piezoelectric film mounted between the protection layer and the liquid crystal panel, sensing a pressing force applied to the touch-sensing surface to generate electric power; and

    a battery module connected to the piezoelectric film and the liquid crystal panel, saving the electric power generated by the piezoelectric film and providing the electric power to the liquid crystal panel.
