A display device according to an exemplary embodiment of the present disclosure includes a display panel having a display area, a back cover disposed on a rear surface of the display panel, a first roller which winds or unwinds the back cover and the display panel, and a second roller which is disposed above the first roller to move in a vertical direction, the back cover and the display panel being overlaid on the second roller. The emission area is flexibly adjusted during the partial view so as to suppress a burn-in issue and improve the lifespan of the display device.

A display device includes: a display panel which displays an image; and a frame set disposed on a rear side of the display panel, where the frame set bends the display panel. The frame set includes a frame including a body extending in a longitudinal direction and a head protruding toward the rear side of the display panel from the body, and a wire fixed to the head and extending in a longitudinal direction of the frame.

Methods and apparatus provide for: receiving an embedded image having different information embedded in an unused area of a rectangular image format for transmitting a primary image obtained by correcting beforehand an original image in a manner canceling out the distortion thereof that appears when viewed through lenses of a head-mounted display; outputting directly to a panel of the head-mounted display the embedded image received by the receiving section; and recomposing the different information by extracting the data thereof from the unused area for the embedded image.

The present invention gives a strong sense of immersion to a user. A head mount display (100) includes: a housing (1); a display section (2) which is provided in the housing and displays an image (I); a lens (3a, 3b) which is provided in the housing and through which the display section (2) is visible to a user; and at least one light emitting section (4) which is provided in the housing (1) and emits light with which to illuminate a circumference of a counter surface (3a-1, 3b-1) of the lens (3a, 3b) which counter surface faces an eye of the user.

A display device which can be put together without hooks or fasteners includes an outer frame and a backplane. The outer frame includes a side frame and a T-shaped fixture block protruding from the side frame. The backplane includes a side board. A T-shaped groove is formed on the side board. The T-shaped groove extends through the side board. The T-shaped groove includes a first groove and an inwardly extending groove communicating with the first groove. The fixture block can be inserted into or removed from the first groove. The fixture block can be moved along the inwardly extending groove to engage with the two sides of the inwardly extending groove.

A structure for attaching portions of a display device which provides connection strength and aesthetic enhancement includes a first locking component, a second locking component, and a connecting component. A first connecting groove is formed on the first locking component and a second connecting groove is formed on the second locking component. The first and second connecting grooves are opposing but interconnected. The connecting component is made of a silicon gel analogue, and is injected into the first and second connecting grooves before being stiffened in place by a curing process.

An audio-visual system may include a housing comprising an open upper end and a storage space, an audio-visual device installed inside the housing and exposable through the open upper end, and a lifting device configured to expose or store the audio-visual device inside the housing through the open upper end. The audio-visual device may include a display, a speaker, and a processor configured to control the audio-visual system to operate in a first mode for outputting media art content while the display is stored in the housing according to a first event, operate in a second mode for outputting audio content through the speaker while part of the display is exposed through the open upper end according to a second event, and operate in a third mode for outputting a visual content while the entire display is exposed through the open upper end according to a third event.

With an image display apparatus, such as a head-mounted display, the eyes of a user observe an image displayed on a display panel through an eyepiece in an enlarged manner. A microlens array sheet that is one example of an optical element functioning as an optical lowpass filter is inserted in an optical path running from the display panel to the eyepiece.

According to an aspect, an apparatus may include a media streaming device including electronic circuitry configured to receive media content wirelessly from a media content source, and an output cord segment having a first end portion integrally coupled to a structure of the media streaming device, and a second end portion configured to be coupled to a receiving device, where the electronic circuitry is further configured to transmit the received media content through the output cord segment to the receiving device. The apparatus may include a power cord segment having a first end portion configured to be coupled to the media streaming device, and a second end portion configured to be coupled to a power source.
