However, a person skilled in the art would appreciate that the display apparatus according to the concept of the present invention may be any display apparatus including at least one display unit and can be extendible by increasing the number of the display units.

In the following description, in a properly operating state of a video wall according to embodiments of the present invention, a “front side” indicates a side of a video wall facing a user, and a “rear side” indicates a side of a video wall opposite to the front side, a longitudinal direction indicates a left-right direction relative to the user, and a height direction indicates a up-down direction relative to the user.

As shown inFIGS. 1 and 2, an assembling frame100for a display unit of a video wall according to an exemplary embodiment of the present invention comprises: two rectangular side frames10disposed opposite to each other in the longitudinal direction, at least one front side cross beam12connected between two front side vertical posts11of the two rectangular side frames10, at least one rear side cross beam14connected between two rear side vertical posts13of the two rectangular side frames10, and at least one hanging member. Each of top cross beams15and bottom cross beams16of the two rectangular side frames10is provided with at least one first fitting hole17extending in the height direction, and each of the front side cross beams11and the rear side cross beams13of the two rectangular side frames10is provided with at least one second fitting hole18extending in the longitudinal direction. Hanging members20are mounted to at least one of the front side cross beams12for detachably connecting to a rear side of a display unit200.

In one exemplary embodiment, the first fitting holes17disposed respectively in the top cross beam15and the bottom cross beam16align with each other in pair in the height direction, so as to facilitate connecting two assembling frames100in the height direction; furthermore, the second fitting holes18disposed respectively in the front side cross beams11or the rear side cross beams13align with each other in pair in the longitudinal direction, so as to facilitate connecting two assembling frames100in the longitudinal direction.

In the embodiments of the present invention, the type of the display unit200could be, for example, a liquid crystal display (LCD) screen, or an organic light-emitting diode (OLED), which is not specifically limited herein. In order to reduce the seams between the display units of the video wall to be formed, the shape of the assembling frame100should substantially match the shape of the display unit200, and in such a manner, when a user watches the video wall from the front side of the video wall, not only the assembling frame100cannot be seen, but also the seams between the display units200are minimized, so that a better display performance can be achieved.

The numbers of the front side cross beams12and the rear side cross beams14are not specifically limited herein. With reference toFIGS. 1 and 2, there are two front side cross beams12disposed close to the top cross beams15and the bottom cross beams16of the rectangular side frames10, respectively; there are two rear side cross beams14disposed close to the top cross beams15and the bottom cross beams16of the rectangular side frames10, respectively. With such a design, the assembling frame100can be made stable and solid and in turn a structure of the video wall can be made stable and solid. The display unit200is hung from a front side cross beam12, a top of the display unit is flush with the top cross beams15of the rectangular frames10, sides of the display unit are flush with the front side vertical posts11, and the seams between adjacent display units200are minimized.

Optionally, the front side cross beam12and the rear side cross beam14are welded or detachably connected between the two rectangular side frames10, respectively. The assembling frame100may be made, for example, from aluminum section material. The assembling frame100made from aluminum section material can significantly decrease an entire weight of a video wall, such that assembling, disassembling, and moving of the video wall are facilitated.

In an exemplary embodiment, a fastener19comprises a bolt and a nut, so that it is easy to mount and detach the fastener, and it has a good exchangeability. With the assembling frame100according the embodiment of the invention, two adjacent assembling frames100in the height direction may be fixedly connected by a fastener19fitted with the first fitting hole17at a connection position, and two adjacent assembling frames100in the longitudinal direction may be connected by a fastener19fitted with the second fitting hole18at a connection position, so as to form a video wall that is arbitrarily extendable in the transverse and/or the longitudinal directions, and thereby the flexibility of application of the video wall is improved. In addition, adjacent assembling frames100are connected by fasteners19, display units200are hung from the front side cross beams12of the assembling frames100, such that assembling and disassembling of the video wall are very easy.

As shown inFIGS. 3 and 4, according to a further embodiment of the invention, there is provided a video wall, which comprises: a plurality of assembling frames100according to above mentioned embodiments arranged in an array, a plurality of fasteners19, and at least one row of display units200, a back side of each display unit200is hung from a front side cross beam12of a corresponding assembling frame100by a hanging member20(as shown inFIGS. 1 and 2). Two adjacent assembling frames100in the height direction are connected by a fastener19fitted with the first fitting hole17, and two adjacent assembling frames100in the longitudinal direction are connected by a fastener19fitted with the second fitting hole18.

As shown inFIG. 4, the lowermost one or more row(s) of the assembling frames100(the number of the rows is not specifically limited and can be selected based on a height of the screen of the video wall) may also be used as a supporting base without any display unit being mounted thereto. The video wall can be extended arbitrarily in the transverse direction (vertical direction) and/or the longitudinal direction, a flexibility of application of the video is thereby improved. In addition, adjacent assembling frames100are connected by fasteners19, display units200are hung from the front side cross beams12of the assembling frames100, such that assembling and disassembling of the video wall are very easy.

Please refer toFIG. 2, in an exemplary embodiment, the hanging member20comprises a connecting portion201connected to the back side of the display unit200, and a horizontal hanging portion202and a vertical hanging portion203connected to the front side cross beam12. With a hanging member having such a structure, the display unit200can be securely hung from the assembling frame100and cannot be detached easily. Furthermore, each front side cross beam12having a hanging function supports a corresponding display unit200through at least two hanging members20, such that the display unit200can be more stably and securely hung from the assembling frame100.

The horizontal hanging portion202and the vertical hanging portion203are provided with fine adjustment screws21, respectively. Through adjusting an amount of rotation of the fine adjustment screw21, the positions of the display unit200in the height direction and in the front-rear direction (transversal direction) can be adjusted. The display unit200can also be moved leftward or rightward to adjust its longitudinal position. The video wall is easy to be adjusted freely with high precision, so that it has a better display performance.

Taking a video wall having display units arranged in a 2*2 array as an example, when assembling the assembling frames100, two adjacent assembling frames100in the height direction are connected by a bolt and a nut fitted with the first fitting hole17at a connection position, and two adjacent assembling frames100in the longitudinal direction are connected by a bolt and nut fitted with the second fitting hole18at a connection position. There are 2*3 assembling frames, as shown inFIG. 3. Two assembling frames10at the bottom are used as a supporting base for supporting four assembling frames100above the supporting base, the four assembling frames100are used to mount LCD screens. The LCD screens are hung from the front side beams12of corresponding assembling frames100by hanging members20at the back side of the LCD screens, as shown inFIG. 4. If the video wall needs to be extended in the vertical and/or the longitudinal direction, a user only needs to assemble additional assembling frames and mount corresponding LCD screens. When the video wall needs to be detached, a user only needs to remove the LCD screens, dismount corresponding bolts and nuts, so as to separate the adjacent assembling frames, so that the detachment of the video wall is very easy.

Obviously, various changes or modifications can be made by those skilled in the art without departing from the principles and spirit of the disclosure. If those changes and modifications fall into the scope of the claims and their equivalents, then the present invention is intended to include such changes and modifications.
