1. Technical Field
The present disclosure relates to the field of display technologies, and particularly, to a spliced display device and a display system, and more particularly, to a spliced display device and a display system with high structural strength.
2. Description of the Related Art
A spliced display device is a large-scale screen display system which is integration of ultra-thin rim liquid crystal displaying technology, TV wall splicing technology, multi-screen graphic processing technology, network technology, and the likes, which has high brightness, high resolution, high definition, high intelligent control and advance operation, and, which can be connected/integrated well with user monitoring system, command dispatching system, network information system, and the likes, to form a technically perfect, fully functional interactive information displaying and management platform. Nowadays, conventional spliced display device is consisted of several independent display modules connected by fasteners such as screws. Since transparent liquid crystal panels are usually served as screen in the spliced display device and no fastening component should be employed at back of a display region of the screen, they are fixed to each other at the splicing place, by fasteners such as screws, accumulating all the forces on rims of these panels at the splicing place. Moreover, the rims usually have thinner structure and are easy to deform under the action of external force after the splicing. Thus it can be seen, the spliced display device which is fixed by fasteners such as screws is complicated in operation, has low structural strength, and is easy to deform.
Accordingly, in order to overcome and/or alleviate the abovementioned defects, there requires a spliced display device which is difficult to deform and owns high structural strength.
According to one aspect of the present disclosure, there is provided a spliced display device, comprising: a frame; and a plurality of display modules; wherein the plurality of display modules is spliced into an image displaying region, and the frame is disposed around a periphery of the image displaying region.
According to another aspect of the present disclosure, there is provided a display system comprising the abovementioned spliced display device.
These and/or other aspects and advantages of the present disclosure will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
1-clasp, 2-display module, 23-clasp hole, 3-frame, 31-transverse frame part, 32-longitudinal frame part, 35-mounting hole, 4-fastener, 5-cross, 51-securing hole, 6-connection element, 61-longitudinal connection element, and, 65-joint.
In order to provide a more clear understanding of objects, technique solutions and advantages of the present disclosure, the present disclosure will be further described hereinafter in detail in conjunction with preferred embodiments and with reference to the attached drawings. Obviously, the embodiments illustrated in these drawings are only disclosed simply as an example of an embodiment. For those skilled in the art, other embodiments may be achieved by referring to the following embodiments without involving any inventive steps.
In the description of the present disclosure, it should be noted that, unless otherwise specified and defined definitely, terminologies “mount”, “connect to”, “connect with” and the likes should be explained and illustrated in a broad sense, for example, it can be a fixed connection, or a detachable connection, or an integrated connection; or, it also can be a mechanical connection or an electrical connection; or else, it can be a direct connection or an indirect connection with an intermediate agency. For those skilled in the art, the above terminologies can be explained and illustrated in specific situations in the present disclosure.
Referring to
Moreover, referring to
It should be noted that quantity and form of the display modules 2 are not specified and can be modified depending on practical situation. For example, if the number of the display modules 2 is preferably four, then the display module 2 is in a rectangular form. Of course, other quantity and form of the display modules 2 fall into the scope of the present disclosure.
Moreover, transparent liquid crystal panels are served as the display modules 2 and are mounted on the frame for panels respectively. Locating holes (which are hidden under the clasps 1 in the figure) for securing clasps 1 or the fasteners 4 such as clasps screws therein are formed on the frame for panels. During assembly of the plurality of such display modules 2, clasps 1 or screws 4 may be secured respectively into locating holes of these adjacent frames for panels, in order to splice these display modules 2 together, while the frame 3 is provided around the periphery of the display modules 2 after the splicing, achieving reinforcement.
A spliced display device according to a second embodiment of the present disclosure will be described, wherein technical contents of the second embodiment which are the same as those of the first embodiment are omitted to avoid duplicating description, although such technical contents of the first embodiment can be employed in the second embodiment.
The second embodiment is different from the first embodiment in that, referring to
Specifically, in the present embodiment, the display modules 2 are arranged in a matrix, e.g., a 2×2 matrix. Of course, the number of the display modules 2 can be others greater than four. The cross 5 is placed in a juncture among four display modules 2 (i.e., a crossing point among splicing faces of the four display modules 2) and is connected to the display modules 2 by fasteners such as screws. A plurality of securing holes 51 for passing the fasteners 4 such as screws therethrough is formed in the cross 5. When in use, every end of the cross 5 is connected with adjacent edges of every two of the display modules 2 by the fasteners 4 such as screws. Of course, for mounting of the cross 5, a crossed groove for receiving the cross 5 may be formed among the display modules 2. Such cross 5 enhances structural strength of the whole device without interfering displaying of the image.
A spliced display device according to a third embodiment of the present disclosure will be described, wherein technical contents of the third embodiment which are the same as those of the second embodiment are omitted to avoid duplicating description, although such technical contents of the second embodiment can be employed in the third embodiment.
The third embodiment is different from the second embodiment in that, referring to
It should be noted that, the connection element 6 itself may be an integrated connection element, or a divided connection element. If the connection element 6 is an integrated one, the connection element 6 has a shape corresponding to the splicing face and is entirely engaged on the display modules 2. Alternatively, if the connection element 6 is a divided one, a joint 65 is provided over the cross 5, and the transverse connection elements (not shown in figures) and the longitudinal connection elements 61 are extended along the respective directions of the splicing faces, respectively.
Of course, in order to facilitate the assembling, clasp members (not shown in figures) are provided on the connection element 6 while clasp holes 23 are formed in the display modules 2 for fastening the clasp members therein, to achieve a fast assembling.
The present disclosure also provides a display system comprising: the abovementioned spliced display device and a drive circuit board for driving the spliced display device for generating an image.
Concerning the above, the spliced display device according to the present disclosure adopts an image displaying region consisted of a plurality of display modules and reinforces these display modules by components including the frame, the cross, the connection element, and so on, which effectively enhances structural strength of the display device so that it is difficult to deform under the action of external force.
Purposes, technical solutions and advantageous effects of the present disclosure have been further illustrated in the above specific embodiments. It should be understood that the above description is merely used to illustrate specific embodiments of the present disclosure, but not to limit the present disclosure. All of changes, equivalent alternatives, improvements, made within principles and spirit of the disclosure, should be included within the scope of the present disclosure, and the scope of which is defined in the claims and their equivalents.
