Abstract
An apparatus and method for controlling an input power according to power management modes of a display device. In a saving mode of the power management modes, a power supply to the system is turned OFF according to an organic operation between components of the system. Thus, because the power supply to a power block within the system is turned OFF all, a consumed power is in a substantially zero state, comparable to a state in which a power plug is physically pulled out.

A method for controlling an input power via a controller, a display, a power supply including a main power supply block and a standby power supply block, a user command input, and a switch unit, the method comprising:
- inputting a user command for setting a power management mode via the user command input;
- displaying at least two or more power management modes on the display;
- selecting a power saving mode among the two or more power management modes in response to a user selection;
- controlling the switch unit via the controller to turn off all power supplied to a system including the controller and the standby power supply block when the power saving mode is selected;
- and
- when the power saving mode is performed, controlling the command to turn OFF the main power supply block before turning OFF the standby power supply block.
An apparatus configured to control input power in accordance with a plurality of power management modes, comprising:
- a power supply having a main power supply block and a standby power supply block;
- a user command input device configured to receive a user input;
- a display configured to display at least two or more power management modes;
- a controller configured to select a power saving mode among the two or more power management modes in response to a user selection;
- and
- a switch unit configured to control to turn off all power supplied to a system including the controller and the standby power supply block under the control of the controller when the power saving mode is selected,
- wherein, when the power saving mode is performed, the controller turns off the main power supply block before turning off the standby power supply block.
