Abstract
Provided is a display device of the present invention that includes a scanning mirror drive unit that drives a scanning mirror such that, in a case where two or more mutually different non-resonant axial direction scanning speeds are used in a drawing region of one frame of a video formed by a laser light scanning, non-resonant axial direction scanning speed gradually changes between the different non-resonant axial direction scanning speeds. The display device further includes a hologram element that condenses laser light near a pupil to cause the laser light to reach a retina, the laser light being scanned by the scanning mirror.
Claims12
A display device, comprising:
- a scanning mirror drive unit configured to drive a scanning mirror between a first non-resonant axial direction scanning speed of a plurality of non-resonant axial direction scanning speeds and a second non-resonant axial direction scanning speed of the plurality of non-resonant axial direction scanning speeds, wherein
- a non-resonant axial direction scanning speed of the scanning mirror gradually changes between the first non-resonant axial direction scanning speed and the second non-resonant axial direction scanning speed,
- the scanning mirror is driven with the plurality of non-resonant axial direction scanning speeds in a drawing region of one frame of a video, and
- the video is generated by a laser light scanning process by the scanning mirror;
- and
- a drawing system configured to emit a plurality of laser beams on the scanning mirror, wherein a first beam diameter of a first laser beam of the plurality of laser beams is different from a second beam diameter of a second laser beam of the plurality of laser beams.
