Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] This utility model provides a composite connector 10, which includes a silicone connecting strip 11 and a steel sheet 12. Both ends of the silicone connecting strip 11 are provided with protrusions 111, and a first fixing hole 112 is provided through the protrusion 111. The steel sheet 12 is mounted on the silicone connecting strip 11, and both ends of the steel sheet 12 are located within the protrusions 111. The steel sheet 12 is provided with a second fixing hole 121 corresponding to the first fixing hole 112. The second fixing hole 121 is concentric with the first fixing hole 112, and the diameter of the second fixing hole 121 is larger than that of the first fixing hole 112.

[0035] This invention utilizes a composite connector 10 consisting of a silicone connecting strip 11 and a steel sheet 12. The steel sheet 12 and the silicone connecting strip 11 can be integrally molded in a mold. Protruding posts 111 extend from both ends of the silicone connecting strip 11, and first fixing holes 112 for connecting two display panels are provided on the protruding posts 111. The steel sheet 12 has second fixing holes 121 corresponding to the first fixing holes 112. Since the first fixing hole 112 is located within the second fixing hole 121, the steel sheet 12 can provide restraint when significant relative stretching or sliding occurs between the two display panels after they are connected via the first fixing hole 112, thus ensuring the connection stability of the composite connector 10. Furthermore, because the silicone connecting strip 11 can deform relative to the steel sheet 12, the two display panels connected by the composite connector 10 can also undergo a significant bending amplitude after splicing.

[0036] Furthermore, an annular positioning groove 113 is provided on one side of the protruding post 111. The center line of the annular positioning groove 113 coincides with the center line of the first fixing hole 112. The end of the steel sheet 12 is located at the bottom of the annular positioning groove 113. An annular positioning magnet 114 is provided inside the annular positioning groove 113, and the annular positioning magnet 114 can be connected to the steel sheet 12.

A plurality of first protrusions 211 are provided on the back of the flexible rectangular light panel 21 along its periphery. The first protrusions 211 are provided with annular fixing grooves 212 and fixing holes 213, wherein the center line of the annular fixing groove 212 is collinear with the center line of the fixing hole 213, and the diameter of the fixing hole 213 is smaller than the inner diameter of the annular fixing groove 212; an annular fixing magnet 214 is fixedly provided in the annular fixing groove 212, and an internal thread is provided in the fixing hole 213. Two first sides of two flexible rectangular light panels 21 abut against each other, and multiple composite connectors 10 are provided at the abutment of the two flexible rectangular light panels 21; one first fixing hole 112 on the composite connector 10 is connected to a fixing hole 213 on one flexible rectangular light panel 21, and another first fixing hole 112 on the composite connector 10 is connected to a fixing hole 213 on the other flexible rectangular light panel 21. The composite connector 10 is used to connect the two flexible rectangular light panels 21.

[0038] Two flexible rectangular light panels 21 are connected by a composite connector 10. The composite connector 10 is made of a steel sheet 12 and a silicone connecting strip 11 integrally formed. The steel sheet 12 is difficult to stretch in length, which ensures that the two flexible rectangular light panels 21 can be relatively tightened. In addition, since the silicone connecting strip 11 itself has a certain deformation capacity, the two flexible rectangular light panels 21 can also be bent relatively.

[0039] In a preferred embodiment, the front side of the flexible rectangular lamp panel 21 is arrayed with LED beads. The back side of the flexible rectangular lamp panel 21 is provided with electronic components electrically connected to the LED beads.

[0040] Furthermore, the display unit also includes a flexible cover plate 23. The back of a pair of flexible rectangular lamp panels 21 are attached to the flexible cover plate 23.

The flexible cover plate 23 also has connecting clearance protrusions 232 corresponding to the composite connecting member 10. The flexible cover plate 23 also has clearances corresponding to electronic components.

[0041] Finally, two male connectors protrude from the control box 22. A female connector 215 protrudes from the back of the flexible rectangular lamp panel 21; a strip-shaped hole 233 is provided through the flexible cover plate 23, through which the female connector 215 can pass and mate with the male connector. On the flexible cover plate 23, a second protrusion 234 is provided at both ends of the strip-shaped hole 233, and the second protrusion 234 is provided with an internal thread hole. The control box 22 includes an adapter base plate and a rear cover.
