Abstract

Embodiments of the invention include a method, device and/or system (100) for spoke recovery. A method for spoke recovery in a sequential multi-primary color display may include producing a primary color image component (102) corresponding to a first primary color (104) during a display period including at least a portion of a spoke period of the first primary color and a second primary color (104).
