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 scanning mirror configured to scan the light beam along a first scanning direction across the associated display region, and a polygon scanning mirror to scan the light beam along a second scanning direction across the associated display region.
Claims20
A display system comprising:
- 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 including
- a resonant scanning mirror configured to scan the light beam along a first scanning direction across the associated display region, and
- a polygon scanning mirror configured to scan the light beam along a second scanning direction across the associated display region, the polygon scanning mirror having a plurality of facets,
- wherein the beam scanning module is configured to cause, for a first facet of the plurality of facets, the light beam to follow a path including a first plurality of scan lines extending primarily along the first direction and spaced apart along the second direction, and to cause, for a second facet of the plurality of facets, the light beam to follow a path that includes a second plurality of scan lines extending primarily along the first direction and spaced apart along the second direction, the first plurality of scan lines interlaced with the second plurality of scan lines.
