  • Hot-plug extension device and a display having the hot-plug extension device
    Publication number: 20070162677
    Abstract: An LCD display capable of connection to a hot-plug extension device has a microprocessor that includes a detecting port, a signal-out pin and a power pin. The detecting port is connected to at least two detecting switches. A power switch is connected to the signal-out pin and the power pin. The two detecting switches and the power switch are connected to the hot-plug extension device. The microprocessor judges if the extension device is connected to the display correctly using the detecting switch and decides if the power is allowed to activate the extension device.
