Abstract
A display system includes a display screen, a plurality of subsystems, and a control system. The plurality of subsystems each generate an excitation beam that carries image information and a servo beam. For each subsystem, a servo feedback detector receives feedback light of the servo beam, detects the servo feedback mark, and produces a monitor signal. For each subsystem, a control unit is operable to adjust optical energies carried by the excitation beam using a scaling factor. Two adjacent subsystems of the plurality of subsystems are configured such that in operation the areas scanned by the excitation beams of the two subsystems overlap in an overlap region. The control system is configured to determine a range of the overlap region based on the monitor signals from the servo feedback detectors of the adjacent subsystems, and to determine the scaling factors for the excitation beams for the overlap region.
