There are provided: a display unit that is allowed to converge light forming a display image in a pupil of an eyeball and project the light on a retina and that has translucency; and a moving unit that is allowed to move the display unit in triaxial directions of an eye relief direction and two axial directions, the eye relief direction being a direction of a distance between the eyeball and the display unit, the two axial directions constituting a plane perpendicular to the eye relief direction. The moving unit includes a biaxial moving mechanism that is allowed to move the display unit in accordance with a position of the pupil of the eyeball in two axial directions, which are not parallel to each other, constituting a plane perpendicular to the eye relief direction. The moving unit includes an eye relief direction moving mechanism that is allowed to move the display unit in the eye relief direction.

Provided is a display device. The display device includes a main body having a display, an outer box in which a control board configured to control the display is embedded, the outer box being separated from the main body, a first antenna provided in the main body, a second antenna configured to wirelessly communicate with the first antenna, the second antenna being provided in the outer box, an antenna bracket to which the second antenna is coupled, and an antenna mount to which the antenna bracket is coupled, the antenna mount being configured to cover an opening defined in the outer box. The antenna bracket includes an antenna cover configured to cover the second antenna and made of a transparent or translucent plastic material.

An information processing device according to an embodiment includes a detection unit, a determination unit, and a display control unit. The detection unit detects a wearing state of a wearer with respect to a display device that has optical transparency and projects a plurality of content images duplicated from a single content image toward the eyeballs of the wearer. The determination unit determines whether or not the mounting misalignment is occurring with the wearer on the basis of the detection result of the wearing state detected by the detection unit. In a case where the determination unit determines that the mounting misalignment is occurring, the display control unit displays a notification regarding the mounting misalignment on the display device.

Video display systems comprising a video display and a camera assembly are shown and described. In one example, video cameras may be stowed in and deployed from a compartment proximate the upper surface of the display and configured to deploy in an arc-like motion and for rotation about a center of the video camera housing itself. In other examples, video cameras may be aligned with openings in the frame of the television screen and operatively connected to shutter plates that selectively admit light to or block light from the camera. In a further example, video cameras may be provided on motorized mounts that are attached to the frame to collect multiple images for video processing tasks to enhance the video image in a variety of ways.

A display apparatus according to an embodiment of the present disclosure includes: a display cell that displays an image and has a thin-plate shape; one or more vibration exciters that are disposed on rear-surface side of the display cell and cause the display cell to vibrate; and an opposing plate opposed to the display cell with an air gap in between. The display apparatus further includes a sound-spreading adjustment member that is disposed between the display cell and the two or more vibration exciters, and controls spreading of a sound generated by vibration caused by the two or more vibration exciters.

A functional member-attached glass window includes a glass window to be erected on a floor surface and having a glass plate, and a functional member having a surface area smaller than that of the glass plate and arranged at a position apart from and higher than the floor surface, wherein the functional member is pasted to the glass plate via a spacer and joined to the spacer with a fastening part.

An object is to provide an optical system capable of improving the brightness of a main image while eliminating a ghost image. In an optical system including: an image display device that emits an image; a linear polarizer through which light associated with the image passes; a first quarter wavelength plate which receives the light from the linear polarizer; a half mirror; a reflective polarizer; and a second quarter wavelength plate provided between the reflective polarizer and the half mirror, retardance of the first quarter wavelength plate and retardance of the second quarter wavelength plate are equal, and thus the object is achieved.

This disclosure relates to a connection device that can provide a new function for an electronic device. A film antenna receives a wireless signal transmitted by radio, a relay unit relays the received wireless signal to a television receiver, an LED indicator emits light based on a control signal transmitted from the television receiver, a storage case stores the film antenna, the relay unit and a light emitting unit, and a connection member connects the storage case to the television receiver. In addition, in a state of being connected to the television receiver, in a normal direction to a housing surface having a display unit on a housing of the television receiver, the storage case has a protruding section which further protrudes from the housing surface and stores the film antenna in the protruding section. For example, this disclosure can be applied to a receiving device having a receiving unit which receives the wireless signal.
