Head Mounted Display

Abstract

A head mounted display includes first and second light source modules, a light reversely turning module, an image output module, first and second eyepiece modules, and a beam splitting mirror. The first and second light source modules are respectively configured to emit first and second lights. The image output module is configured to receive the first and second lights, generating first and second image lights with corresponding image information respectively. The light reversely turning module is optically coupled between the first light source module (or the second light source module) and the image output module, making a propagating direction of the first light (or the second light) in reverse to that of the first image light (or the second light). The beam splitting mirror is optically coupled between the image output module and the first / second eyepiece module, guiding the first / second image light into the first / second eyepiece module.

Description

RELATED APPLICATIONS[0001]This application claims priority to Taiwan Application Serial Number 105116194, filed May 25, 2016, which is herein incorporated by reference.BACKGROUNDTechnical Field[0002]The present disclosure relates to a head mounted display. More particularly, the present disclosure relates to a stereo head mounted display.Description of Related Art[0003]In recent years, with the increasing development of virtual reality technology, an optical product which can show a stereoscopic image has become a focal point in the consumer market. Conventionally, a head mounted display can respectively provide different images to two eyes of an observer, and the eyes of the observer can respectively receive different image information, so that the observer can perceive a stereoscopic image by exploiting the binocular parallax of typical human sight. However, a conventional head mounted display has a complex structure, a huge size and a heavy weight, which may affect wearing conven...

AI Technical Summary

Benefits of technology

[0004]The disclosure provides a head mounted display, which can reduce a horizontal area of the head mounted display, and can improve a convenience and a comfort of wearing the head mounted display.

[0006]In one or more embodiments of this disclosure, since a configuration of the first light source module, the second light source module and the beam splitting mirror, the head mounted display can respectively provide two eyes of an observer with the different image information (that is, the first image light and the second image light), and then the different image information received by the two eyes of the observer may be combined in a brain of the observer, so that the observer can perceive a stereoscopic image. Furthermore, the light reversely turning module may make the propagating direction of the first light in reverse to the propagating direction of the first image light, so the first light source module and the image output module may be located on different level heights. Similarly, the light reversely turning module may make the propagating direction of the second light in reverse to the propagating direction of the second image light, so the second light source module and the image output module may be located on different level heights. Therefore, the horizontal area of the head mounted display may be reduced, benefiting to minimize the size of the head mounted display.

Problems solved by technology

However, a conventional head mounted display has a complex structure, a huge size and a heavy weight, which may affect wearing convenience and comfort of the observer.
