The display modules 10 are arranged in a one-to-one correspondence with the box portions 20, the display modules 10 are installed on the box portions 20, the box portions 20 are spliced, and a limiting piece 30 is arranged between two adjacent box portions 20. In a specific splicing process, each display module 10 is mounted on a corresponding box portion 20, and a limiting member 30 is disposed between two adjacent box portions 20 when each box portion 20 is spliced. According to the display screen disclosed by the invention, the limiting piece 30 is arranged between the two adjacent box body parts 20, and the movement range between the two adjacent display modules 10 can be limited due to the existence of the limiting piece 30, so that the collision between the two adjacent display modules 10 is avoided, and the problem that the collision between the display modules of the display screen in the prior art can occur is solved.
It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be capable of being practiced otherwise than as specifically illustrated and described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
