Display device with feedback via serial connections between distributed driver circuits
Embodiments relate to a display device that includes a control circuit, an array of light emitting diode (LED) zones, and an array of zone integrated circuits that are distributed in the display area. The zone integrated circuits may comprise integrated LED and driver circuits and may include sensor circuits. The zone integrated circuits are arranged in groups that are coupled to each other and to the control circuit in a serial communication chain via serial communication lines. The control circuit provides control signals that control the driver circuits to drive the LED zones and may provide commands to request readback data from the zone integrated circuits. Responsive to the commands, the zone integrated circuits output readback data to the control circuit via the serial communication chain.
