    • A see-through head mounted display apparatus with reduced eyeglow is disclosed. Two images of a scene are combined and presented to a user, the combined image including portions of reflected image light and light from a see-through view of an external environment. The apparatus includes a light control element to block escaping portions of image light and reflected portions of scene light, while allowing incoming scene light to be transmitted from the external environment. The images are produced using a partially reflecting mirror and a light control element. A portion of scene light is transmitted through the partially reflecting mirror and is combined with a portion of image light reflected from the partially reflecting mirror. A light control element is used to block a portion of the image light and a portion of the scene light to reduce eyeglow.
    • 公开了一种具有减少眼球的透明头戴式显示装置。 将场景的两个图像组合并呈现给用户,组合图像包括反射图像光的部分和来自外部环境的透视图的光。 该装置包括光控制元件,用于阻止图像光的偏离部分和场景光的反射部分,同时允许从外部环境传送入射的场景光。 使用部分反射镜和光控制元件产生图像。 场景光的一部分通过部分反射镜透射并与从部分反射镜反射的图像光的一部分组合。 光控制元件用于阻挡图像光的一部分和场景光的一部分以减少眼球。
