  • Touch screen security protection structure and display device
    Patent number: 10509923
    Abstract: A touch screen security protection structure including a touch screen, a display screen, and a circuit board, a first signal ribbon cable, and a second signal ribbon cable. The first signal ribbon cable and the second signal ribbon cable are respectively connected with the circuit board via zebra stripes, the first signal ribbon cable and the second signal ribbon cable are provided with protection winding wires, and the protection winding wires are electrically connected with the zebra stripes via contacts. When an attacker lifts the touch screen and the display screen by cutting, the first signal ribbon cable and the second signal ribbon cable are dislocated from the zebra stripes, the protection winding wires are disconnected from the zebra stripes, anti-tampering detection signals then trigger the security response mechanism to erase the sensitive data information from the electronic components of the circuit board.
