Abstract (en)

[origin: EP3503081A1] A method of encoding visible light communication information in an image frame to be displayed at a display screen includes measuring the temperature (104) of at least one portion of the display screen during use. The method also includes encoding the visible light communication information in the image frame so as to be displayed at the at least one portion of the display screen. This is done by setting at least one of the luminosity and the hue of the pixels at the at least one portion of the display screen dependent on the measured temperature (104) of the at least one portion of the display screen.
