摘要： A power management circuit includes a control signal reception circuit configured to receive a power control signal for controlling an operation of the power management circuit in correspondence to a driving mode of a panel, from a microcontroller which receives information on the driving mode of the panel; an output signal change circuit configured to change an output signal of the power management circuit in response to the power control signal; a control target selection circuit configured to select a control target circuit to which the output signal is to be transferred; and an output signal transmission circuit configured to transfer the output signal to the control target circuit.
