(1) Select industrial-grade integrated circuit chips whose working temperature is between - 40 ~80 C to prevent the low temperature in winter from making the four-way chips of LED display unable to start.
(2) In order to ensure long-distance visibility under strong ambient light, ultra-high brightness light-emitting four-way diodes must be selected.
(3) The display medium uses a new type of wide-angle tube with wide-angle of view, pure colour and uniform coordination of four-way chips, with a life of more than 100,000 hours. The outer packaging of display medium is the most popular square cylinder with shield, silicone seals and non-metallized assembly. Its appearance is exquisite and beautiful, durable, and has the characteristics of direct sunlight protection, dust prevention, waterproof, high-temperature protection and short circuit protection.

Quality Culture Construction
Quality management always emphasizes the mentality of everyone. To do a good job of quality, we must first have the correct mentality. Then we must conscientiously do everything well and get rid of the "careless" in our work so as to form a quality culture and quality concept. Quality is made by people.
