Near-eye light-field display system

Abstract

A near-eye light field display for use with a head mounted display unit with enhanced resolution and color depth. A display for each eye is connected to one or more actuators to scan each display, increasing the resolution of each display by a factor proportional to the number of scan points utilized. In this way, the resolution of near-eye light field displays is enhanced without increasing the size of the displays.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 62 / 152,893, filed Apr. 26, 2015, which is hereby incorporated herein by reference in its entirety.TECHNICAL FIELD[0002]The disclosed technology relates generally to near-eye displays, and more particularly, some embodiments relate to near-eye systems having light-field displays.DESCRIPTION OF THE RELATED ART[0003]Head-mounted displays (“HMDs”) are generally configured such that one or more displays are placed directly in front of a person's eyes. HMDs have been utilized in various applications, including gaming, simulation, and military uses. Traditionally, HMDs have comprised heads-up displays, wherein the user focuses on the display in front of the eyes, as images are traditionally displayed on a two-dimensional (“2D”) surface. Optics are used to make the display(s) appear farther away than it actually is, in order to allow for a suitable display size to be uti...

AI Technical Summary

Benefits of technology

[0004]According to various embodiments of the disclosed technology, a head mounted display for generating light field representations is provided. The head mounted display comprises an array of lenses (comprising a plurality of light field lenses) positioned opposite and parallel to an array of displays (comprising a plurality of light sources). The array of lenses may be configured to capture light rays from one or more light sources of the array of displays to generate a near-eye light field representation. The head mounted display may include an exterior housing configured to support the edge of the array of lenses, and an interior housing configured to support the array of displays disposed on a surface of the interior housing. In some embodiments, the exterior housing and the interior housing may be positioned such that the distance between the array of lenses and the array of displays remains fixed. In other embodiments, a vertical motion actuator may be disposed between the interior housing and the exterior housing such that the interior housing may be moved vertically relative to the exterior housing to increase or reduce the distance between the two arrays, or vice versa.

Problems solved by technology

Despite the use of optics, however, HMDs generally have low resolution because of trade-offs related to the overall weight and form factor of the HMD, as well as pixel pitch.
