Problems solved by technology

Also, because the present methods seek to collimate light from groups of all pixels, they both lack the ability to control the collimation from pixel to pixel and tend to cause optical aberrations of the collimated rays

Embodiment Construction

[0085] I. Summary

[0086] As noted above, the present invention relates to a head-mounted display device that provides a collimated (or substantially collimated) image to the user through the use of pixel lenses, which may be a separate source of collimation in an optical system, or In some embodiments using curved light reflecting surfaces such as FS / UWA / RO reflecting surfaces, the collimation provided by the pixel lens can be combined with the collimation provided by the curved light reflecting surface.

[0087] Generally speaking, in some specific embodiments, the head-mounted display device is placed directly in front of the user's eyes to bring an immersive experience. In other embodiments, the HMD includes a planar or curved beam splitter, which is used to reflect an augmented reality image display device. The reflective embodiments can be used to produce immersive display devices, if desired, by making non-diffusing reflective surfaces.

[0088] The following discu...

Abstract

A display assembly (515) includes: (a) an image display system (10) which includes an array of pixels (120) and (b) an array of pixel lenses (115). The array of pixel lenses has each lens positioned to collimate or substantially collimate light from a corresponding single pixel of the array of pixels. The display assembly (515) is used in a head-mounted display apparatus (500) which includes a frame (510) to support the display assembly (515) a desired distance from a user's eyes. The head-mounted display apparatus may also include a beam splitter (520) to reflect images from the display assembly (515) to the user's eyes. The head-mounted display apparatus may provide a wide field of view to the user and may be of the augmented-reality or immersive type.
