Abstract
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 a LED, driver circuits, and at least one redundant driver circuit. A non-operational driver circuit is bypassed, and the LED driving responsibility is assumed by the neighboring driver circuit. The neighboring driver circuit may be another one of the driver circuits or the redundant driver circuit.
