Abstract
An exemplary flat panel display includes a micro processing unit, a display signal input socket defining a safeguarding terminal, an input interface configured for a user to input a user code, a first storage unit storing a security code, and a second storage unit storing a safeguarding mark. The micro processing unit is configured to monitor a voltage applied to the safeguarding terminal, detect a status of the safeguarding mark, compare the user code with the security code according to the status of the safeguarding mark, and output a control signal according to a result of the comparison.
Claims14
A flat panel display comprising:
- a micro processing unit (MPU);
- a display signal input socket defining a safeguarding terminal, the safeguarding terminal to be connected with a signal generating device, the safeguarding terminal having a first voltage when it is connected with the signal generating device and having a second voltage when it is unplugged from a display signal output socket of the signal generating device to disconnect with the signal generating device;
- an input interface configured for a user to input a user code;
- a first storage unit storing a security code;
- a second storage unit storing a safeguarding mark;
- a power module connected to said first storage unit, said second storage unit, and said MPU;
- and
- a backup power supply connected to said power module;
- wherein said backup power supply is configured to automatically provide power for said MPU, said first storage unit, and said second storage unit when said safeguarding mark is invalid until said safeguarding mark is valid, the MPU is configured to monitor the voltage applied to the safeguarding terminal, when the MPU monitors that the voltage of the safeguard terminal changes from the first voltage to the second voltage, the MPU changes a status of the safeguarding mark, the MPU compares the user code with the security code according to the status of the changed safeguarding mark, and outputs a control signal according to a result of the comparison.

- a power module connected to said MPU, said first storage unit, and said second storage unit;
- and
- a backup power supply connected to said power module;
- wherein when the MPU monitors that the voltage of the safeguarding terminal changes from the first voltage to the second voltage, the MPU sets the safeguarding mark to be the first code, the safeguarding function of the display is correspondingly activated, when the display is powered on again, the user code matching the security code needs to be input in order to make the display operable if the safeguarding mark is set as the first code;
- and
- wherein said backup power supply is configured to automatically provide power to said power module for said MPU, said first storage unit, and said second storage unit when said safeguarding mark is set as said second code until said safeguarding mark is set as said first code.
