Abstract
The observation optical system introduces light from a first display element and light from a second display element to an exit pupil to present an enlarged combined image of first and second original images. The optical system includes a first optical element allowing the light from the first display element to enter thereinto, a second optical element allowing the light from the second display element to enter thereinto, and a third optical element. The optical system introduces a first light component from a first display area in the second display element to the exit pupil through the second optical element and at least the first optical element, and introduces a second light component from a second display area in the second display element to the exit pupil through the second and third optical elements, not through the first optical element.

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.
