1. A scanning display system, comprising:
- a laser light source comprising two or more offset lasers;
a scanning mirror system configured to scan light from the laser light source in a first direction at a higher frequency, and in a second direction at a lower frequency to form an image;
an eye tracking sensor configured to detect a gaze direction of a user; and
a controller configured to map the gaze direction to a region in the image, control the scanning mirror system to scan the laser light an interlaced pattern to form the image, and adjust one or more of a scan rate in the second direction and a phase offset between a first frame and a second frame of the image based at least on the region in the image.

Abstract
Examples are disclosed that related to scanning image display systems. In one example, a scanning display system comprises a laser light source comprising two or more offset lasers, a scanning mirror system configured to scan light from the laser light source in a first direction at a higher frequency, and in a second direction at a lower frequency to form an image, and a controller configured to control the scanning mirror system to scan the laser light an interlaced pattern to form the image, and to adjust one or more of a scan rate in the second direction and a phase offset between a first frame and a second frame of the interlaced image.

14. A method of displaying an image, comprising:
-
directing light from two or more offset lasers toward a scanning mirror system; scanning light from the two or more offset lasers in a first direction at a higher frequency and in a second direction at a lower frequency to thereby scan the laser light in an interlaced pattern and form the image; mapping a gaze direction determined via an eye tracking sensor to a region in the image; and adjusting one or more of a scan rate in the second direction and a phase offset based on the region in the image. - View Dependent Claims (15, 16)

17. A scanning display system, comprising:
-
a laser light source comprising two or more offset lasers; a scanning mirror system configured to scan light from the laser light source in a first direction at a higher frequency, and in a second direction at a lower frequency to form an image; an eye tracking sensor; and a controller configured to determine a gaze direction via data from the eye tracking sensor, to control the scanning mirror system to scan the laser light an interlaced pattern to form the image, and to adjust one or more of a scan rate in the second direction and a phase offset between a first frame and a second frame of the interlaced image based at least on the gaze direction. - View Dependent Claims (18)
