The LED cube screen usually consists of 5 or 4 LED faces combined into a cube. It can also be spliced into geometric shapes with special shapes, and a small gap connection is realized between the faces. It can be viewed from any angle around it, getting rid of the observation limitations of traditional flat display screens. It is suitable for installation in the atrium of a bar, hotel or commercial real estate, and can give the audience a new visual experience. Compared with conventional LED displays, LED Cube screens pay more attention to structural breakthroughs. LED cube screens are biased towards users with special needs, are currently mainly used in performing arts venues, outdoor media, exhibition hall squares and other environments. Due to the special appearance of the LED cube screen, the structure is very different from the traditional display screen, so the technical requirements for manufacturers are more stringent. If the manufacturers technology is not good enough, the spliced LED cube screen will have many problems such as uneven appearance due to excessive seam gaps and discontinuous splicing surfaces, which will affect the viewing effect and destroy the aesthetics of the overall design. More importantly, the design of the circuit and structure of the LED Cube screen is complex, which places high requirements on the R&D capabilities of manufacturers. The emergence of the LED Cube screen makes the LED special-shaped screen have a better modeling ability. For a long period of time before, LED cube screens were realized by traditional rectangular flat modules assembly or wrapping. When the arc of the display screen is very small and the display form is more complicated, the seams and flatness cannot be solved well, causing problems such as poor display effect, mosaic, etc.
