Pressing device, in particular an electrohydraulic or electromechanical pressing device for pressing a workpiece, comprising a housing, wherein a tool holder is arranged at a first end of the housing, a see-through display is arranged on the housing, and one or more symbols are displayed by the see-through display.

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

An augmented reality glasses system includes a head-mounted display device 100 and a back-mounted device 300. The head-mounted display devices include see-through displays (231,232, figure 2A) and at

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.

Embodiments disclose a real-time surgery method and apparatus for displaying a stereoscopic augmented view of a patient from a static or dynamic viewpoint of the surgeon, which employs real-time three-dimensional surface reconstruction for preoperative and intraoperative image registration. Stereoscopic cameras provide real-time images of the scene including the patient. A stereoscopic video display is used by the surgeon, who sees a graphical representation of the preoperative or intraoperative images blended with the video images in a stereoscopic manner through a see-through display.

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.

Systems and techniques are described for extended reality (XR) operations. An XR system displays virtual content using a display according to display settings. The display settings can identify, for instance, a position, orientation, and / or size of the virtual content as displayed. The environment can be viewable using the display as the virtual content is displayed by the display, for example using a see-through display or a pass-through display. The imaging system can determine, based on one or more attributes of one or both eyes of the user of the imaging system, an extent of perception of the virtual content that is displayed using the display by the user. The attributes can identify, for instance, eye position, eye movement, pupil dilation, saccades, fixations, blinking, and / or squinting. The XR system can determine, based on the extent of perception of the virtual content by the user, a modification to the display settings.

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.
