Head-mounted image display apparatus

摘要

A head-mounted image display apparatus (1) for viewing an image characterised in that it comprises: a main apparatus (10) comprising an image display means for forming an image having a pair of liquid display modules, each module having a liquid crystal display element (42); an enlarging means (45) for virtually enlarging the image; a frontal region support member (23), which is positioned at the frontal region of the head when worn, and an occipital region support member, which is positioned at the occipital region of the head when worn; a securing means for holding the frontal region support member (23) and the frontal region of the head in contact when the main apparatus is worn comprising an inflating/deflating member (8) that can be switched between an inflated condition and a deflated condition at that part of the inside surface of the occipital region support member contacting the occipital region of the head; wherein the enlarging means (25) comprises a single magnifying lens, and each liquid crystal display module satisfies the equation30 x 10-3 ≤ P ≤ 0.0021 x W2 where W2 is the horizontal width of the image display surface of the liquid crystal display element (42) in millimetres, and P is the horizontal pixel pitch in millimetres; and the horizontal view angle of an enlarged virtual image is 30° or greater.
