DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18264608 titled 'DISPLAY DEVICE
Simplified Explanation
The present invention relates to a display device utilizing Foveated rendering technology to eliminate image quality degradation. The device includes a scanning mirror drive unit that controls the scanning mirror to gradually change scanning speeds in different regions of a video frame formed by laser light scanning. Additionally, the device may include a hologram element to focus laser light near the pupil for better retina projection.

Original Abstract Submitted
An object of the present invention is to provide technology for eliminating image quality degradation that may occur in a case where a Foveated rendering technology is utilized. A display device () of the present invention 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. According to one embodiment of the present disclosure, the display device () may further include 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 (). According to another embodiment of the present disclosure, the display device may cause the laser light scanned by a scanning mirror to reach a projection surface without through a projection optical system, or through a projection optical system.
