As an engineering display product, LED display has been widely used in various outdoor display projects since its birth. In practical applications, due to the restrictions of environmental factors, the restrictions on the installation site buildings or the special requirements of the owners, the LED display screens required to be installed usually exhibit irregular shapes, including diamonds, arcs, sectors, cylinders or even Round. Spherical, all kinds of things are not enough.

LED display manufacturers have specially developed special-shaped display modules for these irregular display items. In the actual project development, they also found that the traditional control system and video playback software can not meet these irregular splicing display screens. The normal control and playback of the system, so special control systems and display software have been developed, and some projects even require the design of complex motor drive structures.

The advantages of freely configurable LED display screen are quickly reflected in the field of outdoor display screen. A large number of outdoor display projects have begun to choose LED display. "Special-shaped screen" as a branch of the LED display industry has also been officially established. Nowadays, many companies represented by special-shaped display projects have emerged in the LED display industry, such as Jin Lixiang, Lixiang Meeting, Kangshuo Exhibition, Chuangxian, etc.

In the early special-shaped screen project, due to the limitations of the market and the project itself, many special-shaped modules required technical research and temporary mold-opening customization according to the actual situation of the project, resulting in unification or not. -Repeatability of the project. The whole shaped display market has the characteristics of high technical threshold and high cost, which is difficult to promote. With the advancement of technology and the entry of module manufacturers, the threshold and cost of the entire special-shaped screen market have rapidly decreased.
