As an engineering display product, LED display has been widely used in various outdoor display projects since its birth. In practical applications, due to environmental constraints, restrictions on installation sites and buildings or special requirements of the owner, the LED display required to be installed usually presents an irregular shape, including diamond, arc, fan, cylindrical 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 projects. In the actual project development, they also found that the traditional control system and video playback software could not meet these irregular splicing displays. For normal control and playback of the system, special control systems and display software have been developed. Some projects even require the design of complex motor drive structures.

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

In the early special-shaped screen project, due to the limitations of the market and the project itself, many special-shaped modules need to be technically researched and temporary mold customization based on the actual situation of the project, leading to unification or not. -The repeatability of the project. The entire special-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 been rapidly reduced.
