Abstract
Described herein are display devices, and methods for use therewith. Such a device can be used to display one or more virtual images within a first see-through portion of the device, adjacent to which is a second see-through portion that does not overlap with the first see-through portion. The first and second see-through portions of the device collectively cover a substantially entire field-of-view (FOV) of a user. A transmittance (and/or other optical characteristic(s)) corresponding to the first see-through portion of the device and a transmittance (and/or other optical characteristic(s)) corresponding to the second see-through portion of the device can be caused (e.g., controlled) to be substantially the same to provide a substantially uniform transmittance (and/or other optical characteristic(s)) across the substantially entire FOV of a user. More generally, optical characteristics of see-through portions of the device can be controlled, e.g., by a user and/or through feedback.
