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.

Provided is a display device that includes a middle cabinet in which two display panels of which two rear sides are leaning on each other are safely held, and an incision is formed in at least a portion of a rim of the middle cabinet; a back cover is interposed between the two display panels and has an extension portion that is inserted through the incision and extends to an outside, and a fixing member in which control printed circuit boards that are coupled to the extension portion of the back cover and are connected to the two display panels respectively are embedded.

A wide angle image to be displayed on a screen fixed on the head or the face of a user is processed. When a display view angle reaches a boundary of an original wide angle image 701, an indicator 703 indicating reaching the boundary is added to a free viewpoint image 702. The indicator 703 is apart of the free viewpoint image 702 which is in contact with a boundary 704 of the wide angle image 701 or protrudes from the boundary 704 and is displayed as a black-painted frame. By observing such the indicator 703, the user can intuitively understand that the display area reaches the limit of the wide angle image.

An electronic device, a split television implementation method and a split television are disclosed. The split television implementation method includes: processing, by the processor, a received video signal, such that the video signal is converted into a first signal capable of being transmitted in a wireless manner; sending, by the processor, the first signal obtained via conversion to the playing device; acquiring, by the playing device, the first signal obtained via conversion; and processing, by the playing device, the acquired first signal, and converting the first signal into a video signal capable of being displayed on a display screen. The present disclosure further provides a split television, and the split television includes: a video signal processing module, configured to process a received video signal, such that the video signal is converted into a first signal; a sending module, configured to send the first signal to a playing device; an acquiring module, configured to acquire the first signal obtained via conversion; and a first signal processing module, configured to process the acquired first signal, and convert the first signal into a video signal capable of being displayed on a display screen. According to some embodiments of the present disclosure, aesthetica) shape of the split television is improved, and in addition, arrangement and space restrictions of the split television are also reduced.

A modular electrical system for controlling a liquid crystal display (LCD) contained within a chassis. The system may include a backplane in communication with a power module and video module through connectors on the back plane and respective connectors on the modules. The system may also include a timing and control board (TCON) that is in communication with the backplane via conduction lines that are provided to carry power, video signals, etc., to the TCON. Guides may be provided to ensure proper alignment of the power module and video module with the backplane. In some embodiments, the power module and video module may include input and output connectors that facilitate connection of multiple displays in a daisy chain fashion.

The present invention involves a display panel and a display device. The display panel includes a display surface for displaying images, and the display surface is concave when being viewed in front of the display surface. The display panel can provide a good sense of presence when displaying images.

A head-up display device includes: a cover having a light-transmissive light exit part; a first case mating with the cover and having a light entry part for entry of display light and a housing part housing a reflecting member; a light source unit outside the housing part; and a second case covering the light source unit and fastened to the first case. The device has a heat radiator of higher rigidity than the second case, having a wall part that externally projects from the housing part through the intervening light entry part, the light source unit affixed to the wall part to diffuse the heat from the light source unit; and includes a mating part in which the second case and the wall part mate together, the second case fastened to the heat radiator at locations to either side of the mating part.

A display unit (1) includes a transparent plate (11) and a display body. The transparent plate has a first surface and a second surface that are opposite to each other, and is disposed to allow substantially an entire region of the first surface to be exposed. The transparent plate has a curved shape that is bent in an arc shape in a first direction. The display body is joined to side of the second surface of the transparent plate to follow the curved shape.
