Abstract

A see-through, near-eye mixed reality head mounted display (HMD) device includes left and right see-through display regions within which virtual images are displayable. These left and right see-through display regions each having a transmittance that is less than one hundred percent. The see-through, near-eye mixed reality HMD device also includes a see-through transmittance compensation mask that includes a left window through which the left see-through display region is visible and a right window through which the right see-through display region is visible. In accordance with various embodiments, the see-through transmittance compensation mask is used to provide a substantially uniform transmittance across the field-of-view of a user wearing the HMD device.
