Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit or scope of the utility model, which is therefore not limited to the specific embodiments disclosed below.

It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

A display screen comprises a frame and a display module, wherein the display module is fixedly connected with the frame. In some embodiments, the frame is a rectangular shelf. The display module assembly includes lamp plate and drain pan, the lamp plate with drain pan fixed connection. The lamp panel comprises a circuit board and LED lamp beads, and the LED lamp beads are fixed on the circuit board.

Referring to fig. 1, the bottom shell includes splice plates 1 and elastic connectors, the number of the splice plates 1 is more than two, and two adjacent splice plates 1 are partially overlapped. Two adjacent splice plates 1 are fixedly connected through the elastic connecting piece. The elastic connection member is capable of bending. Adopt the drain pan of concatenation, when adjusting the radian of display screen, the radian of cooperation display screen that the drain pan can be better is adjusted.

Referring to fig. 2, in some embodiments, the splice plate 1 has a first end 101 and a second end 102 opposite the first end 101 in a splice direction X; the splice plate 1 has a first surface 103 and a second surface opposite to the first surface 103 in the thickness direction Y, the first end 101 is provided with a first avoiding notch 104 on the first surface 103, and the second end 102 is provided with a second avoiding notch 105 on the second surface; when two adjacent splice plates 1 overlap, the first avoiding notch 104 of one splice plate 1 is matched with the second avoiding notch 105 of the other splice plate 1, so that two adjacent splice plates 1 are partially overlapped, and the two adjacent splice plates 1 are leveled.

Referring to fig. 2, in some embodiments, the splice plate 1 has a third end 106 and a fourth end opposite the third end 106 in a length direction Z, the third end 106 and the fourth end being provided with a first groove 107. The design of the first groove 107 may facilitate bending of the splice plate 1. In some embodiments, the first groove 107 of the third end 106 is in line with the first groove 107 of the fourth end to further facilitate bending of the splice plate 1.
