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.
Claims19
An apparatus configured to control internal 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;
- an AC or DC power supply connector;
- a switching unit connecting the AC or DC power supply connector to the power supply;
- a processing device operably connected to the main power supply block;
- and
- a controller operably connected to the standby power supply block and configured to control the main power supply block and the switching unit;
- and
- a control signal input configured to receive a user input,
- wherein the controller is configured to
- control an output of the main power supply block in accordance with a first of the plurality of power management modes and in response to the user input, and
- control the switching unit according to a second of the plurality of power management modes.
A method of controlling internal power of an apparatus in accordance with a plurality of power management modes, the apparatus including a power supply having a main power supply block and a standby power supply block, an AC or DC power supply connector, a switching unit connecting the AC or DC power supply connector to the power supply, a processing device operably connected to the main power supply block, and a controller, the method comprising:
- controlling, by the controller, an output of the main power supply block in accordance with a first of the plurality of power management modes and in response to a user input, and
- controlling, by the controller, the switching unit according to a second of the plurality of power management modes.
