Abstract
Embodiments relate to a display device that includes a control circuit, an array of light emitting diode (LED) zones, and an array of driver circuits that are distributed in the display area. An integrated LED and driver circuit includes one or more LEDs of a LED zone and one or more driver circuits integrated on a substrate in a single package with the LED and driver circuit vertically stacked over a substrate. An addressing scheme configures addresses of the driver circuits using address lines that connect between adjacent driver circuits. Control data is provided to the driver circuits via a power line communication signal that provides both a supply voltage and digital data modulated onto the supply voltage.
