1. A display apparatus comprising:
- a display configured to display an image;
a power supply configured to receive input voltage and supply operation voltage for the display; and
a processor configured to output a configuration signal to set a permitted range of the input voltage based on a user'"'"'s selection,wherein the power supply comprises;
a voltage selector configured to selectively prevent generation of the operation voltage from the power supply according to a level of the input voltage when activated, andan activator configured to;
deactivate the voltage selector in response to the configuration signal having a first level such that the power supply supplies the operation voltage regardless of the level of the input voltage, andactivate the voltage selector in response to the configuration signal having a second level such that the power supply supplies the operation voltage if the level of the input voltage is within the permitted range and the power supply does not supply the operation voltage if the level of the input voltage is beyond the permitted range.

9. A power supply comprising:
-
a voltage supplier configured to receive input voltage and supply the input voltage as operation voltage for a display apparatus; a voltage selector configured to selectively prevent generation of the operation voltage from the voltage supplier according to a level of the input voltage when activated; and an activator configured to activate or deactivate the voltage selector based on a configuration signal received from an external source, wherein the activator is further configured to; deactivate the voltage selector in response to the configuration signal having a first level such that the voltage supplier supplies the operation voltage regardless of the level of the input voltage, and activate the voltage selector in response to the configuration signal having a second level such that the voltage supplier supplies the operation voltage if the level of the input voltage is lower than or equal to a level of a reference voltage and the voltage supplier does not supply the operation voltage if the level of the input voltage is higher than the level of a reference voltage. - View Dependent Claims (10, 11, 12, 13, 14)

15. A power control method of a display apparatus, the method comprising:
-
detecting a wakeup signal in a standby mode of the display apparatus; determining whether to activate a voltage selector configured to selectively prevent generation of operation voltage from a power supply for the display apparatus to display a image when activated, based on a configuration signal which is generated based on a user input; and selectively switching from the standby mode to a normal mode based on a level of an input voltage to the display apparatus in response to the voltage selector being activated, wherein the determining whether to activate the voltage selector comprises; deactivating the voltage selector in response the configuration signal having a first level such that the power supply supplies the operation voltage regardless of the level of the input voltage, and activating the voltage selector in response to the configuration signal having a second level such that the power supply supplies the operation voltage if the level of the input voltage is lower than or equal to a predetermined reference voltage and the power supply does not supply the operation voltage if the level of the input voltage is higher than the predetermined reference voltage. - View Dependent Claims (16, 17, 18, 19, 20)
