Image display device and image display system

Abstract

An image display device comprising a display portion that projects, via eyepiece optical systems which respectively correspond to each of the both eyes of a user, a light emitted from a two-dimensionally light emitting type photoelectric device which is perpendicular to the light beam emitting direction onto the eyeballs of said user, a supporting portion that supports the display portion at its portion that is not in contact with the user, and a face contact portion that is supported by the display portion and is capable of changing the distance between the eyepiece optical systems and the eyes of the user, whereby images with high image quality and high field angle are, in a space-saving manner, safely provided to the user, and, at the time, with the personal image display devices' disadvantages being saved, even multiple persons can enjoy the images.

Description

TECHNICAL FIELD [0001] The present invention relates to an image display device that is used with it being positioned near to the eyeballs and relates to an image display system. Background Art [0002] Generally, image display devices can be divided into devices for multiple persons to enjoy images displayed thereon such as televisions and projectors, and personal display devices by which displayed images are enjoyed personally such as personal computers, televisions set in the chairs in an airplane, and cell phones. In the case of the former ones, for multiple persons to appreciate images, the images are required to be displayed at a position distant from the picture plane, and thus there is the disadvantage that there arises a restriction with respect to the size of the display, and, at the time, a large space is required. On the other hand, since the latter ones are for personal use, images may be displayed near the picture plane, and even if the picture plane itself is small, the...

Benefits of technology

[0086] In accordance with the present invention, there can be provided an image display device through which images with high image quality and high field angle are, in a space-saving manner, safely provided to the user, and, at the time, with the personal image display devices' disadvantages being saved, even multiple persons can enjoy the images.

Problems solved by technology

However, in the above-described case where the heavy object is supported by an outside member, since there is the possibility that the heavy object is driven in the vicinity of the face, it is required that it properly follow the face portion and that the risk that the face collides with the heavy object should be evaded.

Further, also in the case of displays for personal use, when the system is structured such that the entire field of vision is light-shielded, there is the disadvantage that the user cannot appreciate images while paying attention to outside information.

While to avoid this disadvantage, with respect to eyeglass type displays and head mount type displays, ingenuities in which, for example, see-through portions through which the peripheral portions can be observed or windows, located at the periphery of the eyeglass, for observing the outside are disposed are made, the ingenuities themselves decrease the sense of reality, and thus there is the disadvantage that the original sense of reality associated with a large screen image cannot be obtained.

Still further, with respect to eyeglass type displays and head mount type displays, there is the disadvantage that while they can be utilized for personal use, multiple persons cannot enjoyably appreciate images.
