Display apparatus and control method thereof
First Claim
1. A display system comprising:
- a display apparatus comprising;
a wireless power receiver configured to wirelessly receive power from an external power source;
a display comprising a display panel configured to display an image based on a received image signal, and a backlight configured to emit light toward the display panel;
a first communication circuitry configured to communicate with the external power source;
a sensor configured to detect a distance between the display apparatus and a user; and
a first controller configured to;
control the backlight to emit the light based on the received power, andtransmit information on the detected distance to the external power source if it is determined that the user is within a predetermined critical distance from the display apparatus, andthe external power source comprising;
a wireless power transmitter configured to wirelessly transmit the power to the display apparatus,a second communication circuitry configured to communicate with the display apparatus, anda second controller configured to, in response to receiving the information on the detected distance from the display apparatus, adjust a level of the power to correspond to the detected distance, and control the wireless power transmitter to transmit the power having the adjusted level to the display apparatus,wherein the first controller is further configured to control the backlight to emit the light based on the received power having the adjusted level for reducing power consumption.

Abstract
Disclosed is a display apparatus including: a wireless power receiver configured to wirelessly receive power from an external power source to supply power to the display apparatus; a display configured to display an image based on a received image signal; communication circuitry configured to communicate with the external module; information acquiring circuitry configured to acquire information about a distance between the display apparatus and a user; and a controller configured to determine consumption power of the display apparatus, to control the communication circuitry to provide information about the determined consumption power to the external module, and to reduce the consumption power of the display apparatus if it is determined based on the acquired information that the user is within a predetermined critical distance of the display apparatus. Thus electromagnetic waves harmful to a human body is controlled to reduce and/or eliminate an affect a user.

11. A method of controlling a display system including an external power source and a display apparatus comprising a display, the display comprising a display panel configured to display an image based on a received image signal and a backlight configured to emit a light to the display panel, the method comprising:
-
wirelessly receiving, by the display apparatus, power from the external power source; emitting, by the display apparatus, a light based on the received power to the display panel based on the received power, transmitting, by the display apparatus, information on a distance between the display apparatus and a user to the external power source if it is determined that the user is within a predetermined critical distance from the display apparatus, the distance being detected by a sensor of the display apparatus, in response to receiving the information on the detected distance from the display apparatus, adjusting, by the external power source, a level of the power to correspond to the detected distance, and transmitting the power having the adjusted level to the display apparatus, and wherein the emitting, by the display apparatus, the light comprises emitting the light based on the received power having the adjusted level for reducing power consumption. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
