1. A capacitive touch screen suitable for use in an interactive information display, said capacitive touch screen comprising:

  • a first transparent glass substrate having a thickness of less than or equal to about 0.3 millimeters, said first transparent glass substrate having a first surface and a second surface;

    a second substrate comprising a transparent rigid substrate having a third surface and a fourth surface, said second substrate having a transparent conductive thin film providing capacitive touch function disposed at said third surface thereof;

    wherein said second surface of said first transparent glass substrate is laminated directly to said third surface of said second substrate in order to form a capacitive touch screen having enhanced durability; and

    wherein said transparent conductive thin film of said second substrate opposes said second surface of said first transparent glass substrate when said second surface of said first transparent glass substrate is laminated directly to said third surface of said second substrate.
