A rotatable display apparatus includes a display panel including a rectangular shape, a plurality of speakers provided at an edge of the display panel, a rotating device provided on a rear surface of the display panel and configured to rotate the display panel, a panel rotation detector configured to detect a rotation state of the display panel, an audio signal processor configured to transmit a left audio signal, a right audio signal, and a mixed audio signal to the plurality of speakers based on the rotation state of the display panel, and a mixer provided in the audio signal processor and configured to generate the mixed audio signal by mixing the left audio signal and the right audio signal at a predetermined ratio.

The present disclosure relates to the technical field of display screen, and provides a display module set and a display screen. The display module set comprises a cabinet frame and a plurality of display modules. The cabinet frame comprises a power box and a plurality of sub-frames located on the left and right sides of the power box. The sub-frames on each side are arranged sequentially in a vertical direction. The plurality of the display modules corresponds to a plurality of the sub-frames on a one-to-one basis. A drive circuit and mounting members of the display module are both provided on a left side and/or right side region. A middle region of the display module is uniformly distributed with a hole structure for sound transmission. The display module is mounted on a corresponding sub-frame via the mounting members of the left side and/or right side region.

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 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.

A display device includes a display screen and a frame disposed around the display device, an infrared receiver and a light guide member, wherein the light guide member has a securing surface through which the light guide member is secured to the frame, the light guide member further including a receiving end and a light exiting surface, the receiving end formed at a display side of the display device, a width of the receiving end in a direction perpendicular to the frame to which the light guide member is secured is narrower than a width of the light exiting surface in the direction. Only a narrower portion of the light guide member can be seen when a human being looks at the display device, thus improving display effect of the narrow frame of the display device.

The display device includes two stands 1 that support a chassis (holder). The stand has a strut, and the strut is fixed to the chassis with a fixing portion that encloses a back side and both horizontal sides of the strut. A first projected portion, which projects toward the strut, is formed on a second plate-like member positioned at one side of the strut, and a second projected portion, which projects at a position nearer to the back compared to the first projected portion, is formed on a third plate-like member positioned at the other side. Between the two fixing portions, positions of the second plate-like member and the third plate-like member are in reverse to each other. Due to difference in the positions of the first projected portion and the second projected portion, the two stands cannot be attached at reverse positions. Once the orientation of one fixing portion is reversed, one fixing portion becomes the other fixing portion, and the two fixing portions are common components.
