1. An integrated pixel structure, comprising:

  • a transistor matrix substrate;

    a color filter substrate disposed above the transistor matrix substrate, the color filter substrate being substantially parallel with the transistor matrix substrate; and

    a liquid crystal layer interposed between the transistor matrix substrate and the color filter substrate,wherein the transistor matrix substrate comprises;

    a first transistor;

    a first storage capacitor connected to the first transistor;

    a second transistor;

    a second storage capacitor connected to the second transistor; and

    a conductive protrusion disposed corresponding to the second storage capacitor and configured to electrically connect the second storage capacitor and the color filter substrate when the color filter substrate is pressed and configured not to electrically connect the second storage capacitor and the color filter substrate when the color filter substrate is not pressed, wherein charges in the second storage capacitor are discharged through the conductive protrusion and the color filter substrate when the second storage capacitor electrically connects to the color filter substrate which is pressed.
