Abstract:
A display device according to the present disclosure includes: a backlight control unit configured to divide the luminescence surface of the backlight into a plurality of areas, and, based on the image signal, (i) perform luminescence control in each of the plurality of areas and (ii) set off periods starting at different times for the plurality of areas. The backlight control unit performs luminescence control in a visible light communication area which is at least one area among the plurality of areas in a period in which the visible light communication signal is output, based on the visible light communication signal, instead of performing luminescence control based on the image signal, and performs the luminescence control based on the image signal, in the visible light communication area, in a period in which the visible light communication signal is not output.
