Problems solved by technology

[0003] The existing bulletin boards are of ordinary frame structure, usually in the form of stickers, using external electric lighting, the form of publicity is single, the installation conditions are limited, and the cost of electricity for long-term lighting equipment is also high

[0004] In my country's machinery factories, the safety education of many workers is very important. In the specific work, in addition to the safety teaching of workers, safety production lectures and other forms, the safety knowledge education and guidance will also be strengthened through bulletin boards. The existing The safety knowledge education bulletin board is not convenient for workers to browse and study, and the display board area is small, the posted content is limited, which affects the reading of the workers, and the display effect is monotonous, which makes it difficult to improve the reading interest of the workers.
