led electronic display screen is in a stage of high-speed development and growing up. nowadays, the market of led display screen is undergoing tremendous changes. in addition to the traditional role of information display, the requirements of appearance are further improved. in order to better meet the requirements of beautiful appearance and diversification and use, the special-shaped display of led is produced. display screen.
compared with conventional led electronic display, special-shaped led display pays more attention to structural breakthroughs. at present, the led special-shaped screen modules mainly have fan, arc, circular and cylindrical, triangular and other structural forms. compared with the conventional led display, the special-shaped led screen is biased towards users with special needs. at present, it is mainly used in entertainment venues, outdoor media, exhibition plaza and other environments. because the appearance and structure of special-shaped led screens are different, the technical requirements for manufacturers are more stringent. if the manufacturer’s technology is not up to standard, the spliced led screen will cause many problems such as uneven appearance due to too large gap and discontinuous spliced surface, which will affect the viewing effect and destroy the aesthetic feeling of the overall design. more importantly, the design of the circuit and structure of the special-shaped led screen is complex, which puts forward high requirements for the r&d capability of the manufacturers.
for a long time before, the special-shaped led screen was assembled or edged by traditional rectangular planar modules. the most common special-shaped led screen was the arc screen with large arc and the circular planar screen. when the radian of the display screen is very small and the display form is more complex, it can not solve the problems of seam and smoothness, resulting in displaying inconsistency and mosaic of the display screen, which makes the overall effect of the display screen poor.
the emergence of soft modules gives the special-shaped led screen a better modeling ability
soft module led display has the characteristics of thin, light weight, minimal volume, high pixel density, flexural surface display and low installation cost. it can meet the display requirements of various screen shapes, provide a variety of screen sizes and sharpness. in addition, it can also design color arrangement that emphasizes characteristics (contrast, color spot, mixing, etc.) according to its use. 。
the connection surface of special-shaped screen of led soft module is different from that of traditional led display. the traditional pcb board is made of glass fibre. the flexible module is equipped with high-strength locking and linking device. the flexible fpc circuit board made of flexible insulating base material is made of rubber. the mask and the bottom shell are all made of rubber, which has high compression and torsion resistance and can be finished. the united states has solved the difficult installation problems of various “roundabouts and roundabouts”.
