A display device includes: a first closed-bottomed lens tube including a first display part on the closed bottom for displaying a first image; a second closed-bottomed lens tube including a second display part on the closed bottom for displaying a second image; and an adjustment mechanism that couples the first lens tube and the second lens tube and is capable of adjusting a distance between the first lens tube and the second lens tube. The adjustment mechanism includes an operable part that adjusts the distance between the first lens tube and the second lens tube.

A display unit of the present disclosure includes one or more display devices that perform image display by making a difference in resolution for each of a plurality of image regions in an original image, and an optical device that corrects optically for distortion of a display image that is caused by performing the image display at the different resolution for each of the plurality of image regions, a position of the image display between the plurality of image regions, or both.

A display apparatus includes: a first lens barrel in a bottomed barrel shape and including, at the bottom, a first display that displays an image; a second lens barrel in a bottomed barrel shape and including, at the bottom, a second display that displays another image; a support member elongated in an arrangement direction of the first and second lens barrels, and supporting, by passing through the first and second lens barrels in the arrangement direction, at least one of the first and second lens barrels to allow the at least one lens barrel to move in the arrangement direction; and temple parts respectively connected to two ends of the support member in the arrangement direction. The first lens barrel includes first and second sound pickup devices, the second lens barrel includes third and fourth sound pickup devices, and the temple parts respectively include fifth and sixth sound pickup devices.

An HMD includes a mounting band for surrounding a head H of a user. The mounting band includes a case, a stretching unit, an adjustment mechanism that adjusts a length of the stretching unit to be accommodated in the case by relatively moving the stretching portion with respect to the case, a winding target member, and a spring member which is fixed at a front portion thereof to the stretching unit and at a rear portion thereof wound on the winding target member and in which an unwinding amount from the winding target member changes according to the length of the stretching unit accommodated in the case. The spring member generates elastic force that acts in a direction in which the stretching portion is accommodated into the case. A first elastic force of the spring member generated by a first unwinding amount and a second elastic force of the spring member generated by a second unwinding amount are equal to each other.

Methods and apparatus provide for carrying out a method for rendering a virtual-three dimensional space on a display, including: acquiring information indicative of a position of a head mounted display worn on a head of a user; acquiring information indicative of a position of an input apparatus for use by the user; acquiring information indicative of an instruction entered in the input apparatus; and generating an image of the virtual three-dimensional space to be displayed on the head mounted display at a viewpoint position and a sightline direction, wherein the generating includes generating an image of the input apparatus at the position in the image determined on a basis of a relative position between the head mounted display of the input apparatus, and wherein the generating includes generating an image of an object which is emitted from the input apparatus in response to the user manipulating the input apparatus.

Provided is a display device. The display device includes a display panel including two long sides extending in a first direction and two short sides extending in a second direction, a first sound generator on a first area of one surface of the display panel, the first sound generator outputs a first sound by vibrating the display panel, a second sound generator on a second area of the one surface of the display panel, the second sound generator outputs a second by vibrating the display panel, a bottom frame on the one surface of the display panel, and a first blocking member between the one surface of the display panel and the bottom frame and along edges of the display panel, the first blocking member includes at least one opening.

The present invention relates to a method for displaying an artificial fire pattern in an artificial fireplace. The method comprises the steps of:—providing a first video, which is based on a recorded video of an actual fire pattern of a fire on a physical fireplace element in an actual fireplace,—arranging an artificial fireplace element in an interior of the artificial fireplace, wherein the shape of the artificial fireplace element substantially corresponds to the shape of the physical fireplace element in the actual fireplace,—displaying a first video, in order to create the artificial fire pattern, wherein the first video is, seen along a line of sight, aligned with the artificial fireplace element, such that the artificial fire pattern substantially resembles to the actual fire pattern.

Systems and methods for selecting crossover frequencies for 2.1 speaker systems integrated into electronic displays are described. In an embodiment, an electronic display may include: a left speaker coupled to a left side of an enclosure, a right speaker coupled to a right side of the enclosure, and a subwoofer coupled to the left or right side of the enclosure. In another embodiment, a method may include: determining a position of an asymmetric subwoofer integrated into a display, and selecting a crossover frequency between the asymmetric subwoofer and a set of stereo speakers integrated into the display based, at least in part, upon the position.

A head mounted display includes a frame and an optical member that is fixed to the frame and provides an image. The frame includes a pair of attaching and detaching units to which both ends of a light controller are detachably attached. At least one of the pair of attaching and detaching units is electrically connected to at least one of the both ends of the light controller.
