Abstract
Disclosed is a display device including, from a front face towards a rear face, a panel, a ground plane, and a processing unit connected to the panel and including an antenna for receiving and/or emitting a wave for connection to a wireless network. The display device further includes a plurality of adjustable elements connected to the processing unit, each adjustable element having an impedance which can be modified by the processing unit in order to change the manner in which the wave is reflected and/or transmitted by the adjustable elements, these adjustable elements being located on the rear side of the ground plane.
Claims20
A display device, comprising, from a front face towards a rear face:
- a display panel that generates a visible display on the front face;
- a ground plane that protects the display panel from the electromagnetic environment;
- a processing unit connected to the display panel and configured to control the visible display of the display panel, the processing unit comprising an antenna that at least one of receives and transmits radio waves for connecting the display device to a wireless network which supplies the processing unit with a stream of data for producing images or video on the display of the display panel;
- and
- a plurality of adjustable elements located on the rear side of the ground plane and in connection with the processing unit, each adjustable element having an impedance that is modifiable by the processing unit,
- wherein the processing unit is configured to modify the impedance of each adjustable element to change a manner in which the radio waves are reflected and/or transmitted by the adjustable elements.
