The utility model relates to a penetration attack-proof liquid crystal touch screen. The penetration attack-proof liquid crystal touch screen comprises a liquid crystal touch screen, and is characterized in that N coil loops are arranged on the liquid crystal touch screen; when the coil loops are broken, a warning mechanism is triggered according to electric signal changing of the coil loops; and N is a natural number. By the penetration attack-proof liquid crystal touch screen, the touch screen is provided with a penetration attack-proof protective device, so that penetration attack-proof components are reduced, cost is reduced, and reliability of a system is improved.
