Abstract

The present invention related to a driving circuit including a level shifter. The driving circuit according to exemplary embodiment of the present invention includes a first level shifter, a second level shifter, and a gate driver. The first level shifter includes a path along which a pulse-on current flows in response to an on-control signal and a path along which a pulse-off control flows in response to an off-control signal. The second level shifter includes a path along which an on-current flows in response to the on-control signal and a path along which an off-control flows in response to the off-control signal. The gate driver turns on the switch in response to the pulse-on current, maintains the turned-on switch in the turn-on state in response to the on-control current, turns off the switch in response to the pulse-off current, and maintains the turned-off switch in the turn-off state in response to the off-control current.
