The connector is for the picture signal that comes from the base of the laptop. A flat grey cable will come from the base of the laptop and connect to the connector on the back of the laptop screen. This is a gnd pin of display used to connect the gnd terminal of the microcontroller unit or power source. To do this connect pin 1 on the lcd to the arduinos gnd pin.
