SCANNING MEMS-DISPLAY DEVICE Russian patent published in 2022 - IPC G02B26/10 G02B26/12 G02B27/01 

Abstract RU 2770138 C2

FIELD: computer engineering.

SUBSTANCE: invention relates to scanning systems with a head-mounted display for displaying images. A scanning display system comprising: a laser light source comprising two or more spaced apart lasers; 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; eye tracking sensor configured to detect the direction of gaze of the user; and a controller configured to: correlate the viewing direction with a region in the image, control a scanning mirror system for scanning laser light in an interlaced pattern to form an image, and adjusting one or more of the scanning frequency in the second direction and the phase shift between the first frame and the second frame of the image based on at least said region in the image.

EFFECT: higher accuracy of scanning.
