Abstract
A display system includes a display screen, a light source to generate a light beam to be modulated in accordance with image data, and a beam scanning module to receive the light beams and to direct the light beam onto an associated display region of the display screen. The beam scanning module includes a resonant mirror configured to scan the light beam along a first scanning direction across the associated display region, and a linear scanning mirror to scan the light beam along a second scanning direction across the associated display region. The beam scanning module also includes an integral fold mirror positioned to reflect the light beam from the light source to the resonant mirror.
