To provide a ghost image mitigation in a see-through display with a pixel array.SOLUTION: A head-mounted apparatus includes an eyepiece that includes a variable dimming assembly and a frame mounting the eyepiece so that a user side of the eyepiece faces toward a user and a world side of the eyepiece opposite to the first side faces away from the user. A dynamic dimming assembly selectively modulates the intensity of light transmitted parallel to an optical axis from the world side to the user side during operation. The dynamic dimming assembly includes a variable birefringence cell having a plurality of pixels each having an independently variable birefringence, a first linear polarizer arranged on the user side of the variable birefringence cell, the first linear polarizer being configured to transmit light propagating parallel to the optical axis linearly polarized along a pass axis of the first linear polarizer orthogonal to the optical axis, and a 1 / 4 wavelength plate arranged between the variable birefringence cell and the first linear polarizer.SELECTED DRAWING: Figure 7A

Enterprise communication display systems enable life-like images for videoconferencing and entertainment productions. Life-like images appear in a 3D environment where imaged people are visible through the use of specially configured see-through displays. Various sportsbook venues with presentational displays showing life-size images of people is revealed including venues that serve multiple purposes. Further, a black void illusion is described and is applicable to numerous displays including event and live theater stages and movie theaters. Further, virtual production stages serving a dual mode use of creating life-size images of people to be seen by an audience. Numerous inventive features are described enabling and advancing the black void illusion. Virtual stage lighting is disclosed for simulating stage lights and coordination of virtual stage lights with real stage lights for live and recorded performances.

An XR display system includes a near-eye optical see-through XR display having an image presentation component with an eye-facing side and an outside-world-facing side and configured to present virtual visual content to a user's eye from a location on an image presentation surface of the eye-facing side. A dynamic push-through lens located at the outside-world-facing side and a dynamic pull-through lens located at the eye-facing side each include a liquid crystal cell that is dynamically switchable between an inactive state and an active state by electrical stimulation. In the active state, the dynamic push-through lens converges ambient light approaching the image presentation component from the outside-world-facing side by applying a positive optical power, and the dynamic pull-through lens diverges light exiting the image presentation component from the eye-facing side toward the user's eye by applying a negative optical power.

It is a main object to provide an optical device that suppresses deterioration of light amount balance between RGB of an output display image with respect to input image information when used in a see-through display or the like, and makes it difficult for the color tone to change. An optical device according to the present technology includes: a first light guide plate having a first light guide path formed of a first material; and a second light guide plate having a second light guide path formed of a second material different from the first material, in which the second material has a higher light transmittance than the first material.
