Opacity Filter For Display Device

摘要

An optical see-through head-mounted display device includes a see-through lens which combines an augmented reality image with light from a real-world scene, while an opacity filter is used to selectively block portions of the real-world scene so that the augmented reality image appears more distinctly. The opacity filter can be a see-through LCD panel, for instance, where each pixel of the LCD panel can be selectively controlled to be transmissive or opaque, based on a size, shape and position of the augmented reality image. Eye tracking can be used to adjust the position of the augmented reality image and the opaque pixels. Peripheral regions of the opacity filter, which are not behind the augmented reality image, can be activated to provide a peripheral cue or a representation of the augmented reality image. In another aspect, opaque pixels are provided at a time when an augmented reality image is not present.

主权项

1. An optical see-through head-mounted display device, comprising:
a see-through lens comprising an augmented reality display region and an opacity filter, the opacity filter comprising a plurality of pixels, each pixel is controllable to adjust an opacity of the pixel, and the augmented reality display region extends in a field of view between a first boundary line and second boundary line of the field of view; at least one augmented reality emitter which emits light via the augmented reality display region, the light represents an augmented reality image having a boundary; and at least one control circuit, the at least one control circuit is configured to cause the opacity filter to provide a region having a shape which corresponds to a shape of the augmented reality image, and to provide the region with an opacity which is relatively high when the augmented reality image is at least a specified distance from the first boundary line and the second boundary line.
