A display apparatus may include: a plurality of display modules; and a frame configured to support the plurality of display modules in a matrix arrangement. The frame may include: a first module attachment layer to which some display modules among the plurality of display modules are attached and having a first thermal expansion coefficient; a first frame panel coupled to the first module attachment layer and having a second thermal expansion coefficient different from the first thermal expansion coefficient; and a second module attachment layer to which remaining display modules of the plurality of display modules are attached, having the first thermal expansion coefficient, and disposed adjacently with the first module attachment layer; a second frame panel coupled to the second module attachment layer, having the second thermal expansion coefficient.

Tiled displays having display tiles, are described as well as methods of making and/or operating tiled displays and tiles. Methods and devices are described for a tiled display having tiles lying in an X-Y plane, the methods and devices being for setting or adjusting the position of neighbouring tiles in a tiled display to reduce differences in the Z direction between tiles of a tiled display, whereby the tiles lie in the X-Y plane.

Embodiments of the presently disclosed invention may enable electrical components and connections to be monitored within electrical distribution equipment cabinets having a blanking panel. Such an IR/UV-permitting panel may replace the pre-existing blanking panel in order to monitor the adjacent area having the targeted components and connections to be monitored. NFC tags may be utilized in connection with an IR/UV-permitting panel to enable data acquisition and management systems for the monitoring of electrical components in a cabinet.

Display modules have a plurality of light emitting elements arranged in a predetermined pattern and providing a highly uniform visual effect. Methods are provided to support a plurality of flexible display modules in an adjustable curved arrangement. Alignment and complementary alignment features enable the alignment of adjacent display modules and the creation of large displays from a plurality of aligned display modules. Features to couple to and retain a support frame are provided. Flexible and durable weather resistance features are provided. A system of modular support frames works cooperatively with the display modules, adapting to different mounting environments, and thereby providing large modular displays with desirable properties.

A display device includes: a first display panel; a first housing disposed on the bottom of the first display panel; a first cabinet disposed on the bottom of the first housing, the first cabinet including a first protrusion part and a first concave part; and a first side frame disposed on a side surface of the first display panel. The first side frame is movable toward the first cabinet, and a portion of the first side frame extends to the first concave part. Thus, there may be provided a display device which may be independently used and also be used to constitute (or form) a tiling display device by connecting multiple display devices.

The disclosure provides an electronic device including a support plate and a first panel. The support plate includes a first bridge member and a second bridge member. The first panel is disposed on the support plate and includes a substrate, a signal line, a third bridge member, and a fourth bridge member. The signal line is disposed on the substrate. The third bridge member penetrates through the substrate and is electrically connected to the signal line and the first bridge member. The fourth bridge member penetrates through the substrate and is electrically connected to the signal line and the second bridge member.

Discussed is a display that can include a display panel, a nut fixed to a rear surface of the display panel, a frame including a female thread formed in a fastening hole facing the nut, an outer adjusting member including a hollow portion formed therein having a male thread that is screwed with the female thread of the fastening hole, and an outer head portion protruding out of the hollow portion. An inner fixing member can be further included and can include a thread portion passing through the hollow portion and screwed with the nut, and an inner head portion seated on the outer head portion or the hollow portion.

An exterior display system can be configured and arranged around a structure. The exterior display system includes a mechanical supporting structure configured and arranged about the exterior surface of the structure. This mechanical supporting structure can include various supporting structures and/or mounting structures which are configured and arranged to form a mechanical lattice framework. An electronic visual display device can be connected to the mechanical lattice framework to form the exterior display system. The electronic visual display device can include multiple electronic visual display panels which are connected to the mechanical lattice framework. Each of these multiple electronic visual display panels can include multiple groups of multiple light-emitting diodes (LEDs), also referred to electronic LED disc assemblies, that are configured and arranged in a series of one or more rows and/or a series of one or more columns.

A frame system (3) according to the present disclosure includes a plurality of back frames (4) and a plurality of base frames (5). The plurality of back frames (4) is arranged side by side, and can respectively holds back surfaces of display units (2). The plurality of base frames (5) couples the back frames (4), which are adjacent to each other, in a direction parallel to a floor (F). In addition, each of the back frames (4) and a pair of the base frames (5) coupled to the back frame (4) include an angle adjustment unit (20) that adjusts an angle between the pair of base frames (5).

A mounting and leveling system for an electronic image display device (10) formed of an array of multiple display sections (12) facilitates adjustment of the alignment of adjacent display sections to minimize visible seams between display sections. Some embodiments include one or more magnetically actuated fasteners (220) that facilitate front-access-only installation and adjustment without requiring access to the rear, top, bottom, or sides of the array. Tools (300, 410) for installation and removal of display modules (50) from a front side of the display device are also disclosed. Fasteners (220) for providing a hidden adjustable connection between first and second objects are also disclosed. One such fastener includes a screw (226) having a magnetic head (222) that presents a magnetic moment perpendicular to its axis of rotation (234).
