Abstract: A gate driving apparatus is disclosed. The gate driving apparatus includes a first gate driving chip and N second gate driving chips, wherein N is positive integer. The first gate driving chip has a first input pin and a first current output pin. The first gate driving chip receives a reference electrical signal by the first input pin, and generates a reference current according to the reference electrical signal. The first current output pin is used for outputting the reference current. Each of the second gate driving chips has a current input pin for receiving the reference current and a second current output pin for outputting the reference current. The first gate driving chip and the second gate driving chips generate at least a first output signal and at least N second output signals according to the reference current.
