DISPLAY APPARATUS AND CONTROL METHOD THEREOF
First Claim
1. A display apparatus which comprises an input unit and a screen, the display apparatus comprising:
- the screen comprising a first communication unit which wirelessly communicates with the input unit; and
a first controller which outputs a power mode changing control signal to the input unit through the first communication unit upon occurrence of a wakeup event; and
the input unit comprising a second communication unit which wirelessly communicates with the first communication unit; and
a second controller which changes a power mode of the input unit from a standby mode to a normal mode upon receiving the power mode changing control signal from the first communication unit by the second communication unit.

Abstract
Exemplary embodiments include a wireless transmitter and wireless receiver. The wireless transmitter and wireless receiver wirelessly transmit and receive data, respectively. The wireless transmitter and the wireless receiver each include a controller which outputs a power mode changing control signal to a power supply unit and a communication unit in response to a wakeup event, wherein the power supply unit changes a power mode from a standby mode to a normal mode in response to the power mode changing control signal. Both the wireless transmitter and receiver include a transmitter which transmits the power mode changing control signal to the other. With this configuration, there are provided an apparatus and a control method thereof which enable a wireless transmission of multimedia and consumes minimal power when in a standby mode.
