Abstract
A display system includes a display screen with at least one servo feedback mark in each of a plurality of display regions, and a plurality of subsystems each subsystem configured to generate an image on an associated display region. Each subsystem generate a plurality of scanning beams including an excitation beam and a servo beam, abeam scanning module, a servo feedback detector, and a controller. The beam scanning module includes a resonant scanning mirror configured to scan the scanning beams along a first scanning direction and a linear scanning mirror to scan the scanning beams along a second scanning direction. The controller is configured to receive image data, to modulate the excitation beam in accordance with the image data, and to control timing of modulation of the excitation beam based on the monitor signal to align the modulation with corresponding pixel positions on the display screen.
