Abstract
A source buffer output switch control circuit for controlling operations of a source buffer output switch configured to transmit a source signal output from a source buffer to a display panel or block the source signal includes: a switch driver configured to generate a switch control signal for controlling the operations of the source buffer output switch based on a switch operation input signal; a current limiter configured to limit a driving current applied to the switch driver in order to control a slew rate of the switch control signal; and a bias block configured to supply the current limiter with a bias voltage for controlling a magnitude of the driving current.
