Abstract
A single display device is mounted within a head-worn apparatus to produce both a left image and a right image. The left image is directed to a right eye of the user, and the right image is directed to the left eye of the user. When in the stereoscopic mode, the right and left images differ from each other such that when viewed by the user, the combined right and left images give the user a stereoscopic, three-dimensional effect. When worn on the head of the user, the device is properly aligned to provide the left image to the right eye and the right image to the left eye. Further, as the user moves, the present invention remains properly aligned such that the user can continue viewing the left image with the right eye and the right image with the left eye independent of movement by the user so long as the user keeps wearing the device. A plurality of pixels are collected as the display, wherein each pixel is formed of a grating light valve. The modulation of light by the grating light valve is configured to be accomplished sequentially and also sufficiently fast to multiplex both complete right and left images in a single time frame thereby preventing flicker. By using a single display, the device is inherently aligned to produce an accurate right and left images viewed by each respective eye without internal adjustments. Further, by using the grating light valve, the user is only exposed to reflected light rather than to harmful radiation such as from a cathode ray tube. Additionally, forming the display of grating light valves allows formation of two images without the use of any filters owing to the speed of grating light valves.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
