ABSTRACT:
A display device includes a processor, a memory, an interface and a keypad. The keypad, separably connected to the interface, includes a signal generator. When the display device is connected to a power source, the processor sends a first signal to the interface. The signal generator generates a second signal in response to the first signal. The processor determines whether the second signal is correct based on data stored in the memory. If yes, the display device may be activated. A method for activating the display device via the separable keypad comprises the steps of: connecting the display device to the power source; the display device sending the first signal to the interface; determining whether the second signal is correct; and if yes, activating the display device.
