IMAGE PROJECTION DEVICE AND HEAD MOUNTED DISPLAY

摘要

A head mounted display uses an image projection device comprising: an image generation unit for generating an image; a projection unit for guiding the image generated by the image generation unit to an observer's eyes; and a support for linking the projection unit and the image generation unit. The projection unit has a lens function which makes it easiest to see an image generated by the projection unit at a distance (Lobj) within a range between 30 cm and 3 m. Thereby, the image projection device operates at high resolution, has reduced size and weight, and reduces energy consumption.

主权项

1. An image projection device projecting an image on observer's eyes comprising:
an image generation unit generating an image; a projection unit guiding the image generated by the image generation unit to observer's eye; and a support unit coupling the projection unit and the image generation unit to each other, wherein the image generation unit includes an emitting portion emitting a generated image, the projection unit includes an incident portion receiving the image emitted from the image generation unit, the projection unit has a lens function of making the image generated by the projection unit most visible at a distance in a range of 30 cm to 3 m, and an image is transmitted through air between the emitting portion of the image generation unit and the incident portion of the projection unit.
