It is an object of the present invention to provide a configuration which are less likely to cause a distortion in an observed image when the position of the image display device in the eyeball direction of an observer is adjusted. An image display device according to the present invention includes: an image formation device (40); and an optical system (52) that brings an image from the image formation device (40) to an eyeball (11) of an observer. 0 (degrees).sub.2<.sub.1 is satisfied where an image-formation-device first strike point (CP.sub.1) is defined as a point where an extended line of an optical axis of the optical system (52) intersects with an image exit surface of the image formation device (40), a first normal line (NL.sub.1) is defined as a normal line to the image exit surface of the image formation device (40) passing through the first strike point (CP.sub.1), an image-formation-device second strike point (CP.sub.2) is defined as a point where an extended line of a pupil center line of the eyeball (11) of the observer intersects with the image exit surface of the image formation device (40), a second normal line (NL.sub.2) is defined as a normal line to the image exit surface of the image formation device (40) passing through the second strike point (CP.sub.2), and .sub.1 represents an angle between the extended line of the optical axis of the optical system (52) and the first normal line (NL.sub.1), and .sub.2 represents an angle between the extended line of the pupil center line of the eyeball of the observer and the second normal line (NL.sub.2).

A base mounting assembly and a display device are provided. The base mounting assembly includes a main support on a side of a first device, a base including a pedestal part below the first device and a support post connected with the pedestal part and opposite to the main support, the support post including a first end away from the pedestal part and a second end connecting with the pedestal part, and a cushion block movably provided between the support post and the main support. A distance between the support post and the main support is gradually reduced from the first end to the second end so that when the cushion block is moved between the first end and the second end, a position of the support post relative to the main support is changed, causing a change of a position of the pedestal part relative to the first device.

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 display frame structure and a display device belonging to the field of display technology. The structure may alleviate and/or mitigate the problem for the existing display frame structure and display device that the strength will become weak in case of narrow frame design and the active area is reduced. The display frame structure of the embodiment has a side frame formed integrally with the rear housing or detachably connected to the rear housing, the side frame and the plane of the rear housing may form a recess, which may be used for accommodating the display module. The side frame may wrap a side of the display module. Therefore, a fixing structure for this side of the display module is not required, the design for the front frame may be omitted, and a narrow frame design for the display device may be achieved.

A back plate of a curved display device of the present invention includes a first plate, a second plate, and a plurality of spacer units. The first plate has a first periphery, and the second plate has a second periphery. The second periphery is disposed on the first plate, forming an interlayer space therebetween. The first periphery is fastened to the second periphery. The first plate and the second plate are curved corresponding to each other. The spacer units are distributed in the interlayer space and are connected to the first plate and the second plate.
