Strengthen LED full-color screen technology innovation

As a powerful display device for advertising media and stage applications, LED full-color screens appear in various occasions. At present, every LED full-color screen manufacturer is making technological innovations, such as low-voltage and low-power solutions, small-pitch high-definition solutions, common cathode technology, COB packaging, etc. . In April 2019, under the high attention of the company's leaders, a full-color LED display technical committee was established, Liu Qiang, the R&D director, was appointed as the chairman of the technical committee, and the product manager from the product department, as well as the chief engineer of the LED full-color screen R&D center, Eight PE senior engineers of the Biotechnology Department, deputy managers of the Quality Management Department, and directors of the Engineering Services Department serve as members of the technical committee. From the perspective of the work positions of the committee members, the LED full-color screen technical committee better connects a series of work such as the latest information collection, innovative design, manufacturing, quality assurance, and after-sales service in the industry, forming a technical closed loop. Regarding unresolved technical issues or standards that have not reached a consensus, there is a department that finally solves the problem. In other words, the LED full-color screen technical committee is the most authoritative technical organization of the company.

Since the establishment of the LED full-color screen technical committee, more than 2 technical seminars have been organized every month, and 29 projects have been established in the first quarter of 2019. These projects have clearly defined the person in charge and the work objectives, which allows the committee members to have a clearer and more sense of purpose when carrying out their work, so that they can carry out their work more handily. Up to now, the work of the full-color LED display technical committee is progressing well and some results have been achieved.

The formulation and improvement of the company's quality standards In order to better improve the product inspection standards, inspection methods and inspection items of the company's LED full-color screens, to ensure that the quality of the company's products meets the product design requirements, thereby providing quality standards for product quality control, so that it can meet Customer demand. After many discussions, the technical committee formulated a written system document "LED Full Color Screen Product Inspection Standard", which mainly sets standards for product reliability, appearance, display, performance and packaging, and has achieved preliminary results. In the follow-up, through after-sales feedback on the practical effect, we will continue to improve and optimize, so as to provide our customers with better products and services.

The establishment of the company's standard parts selection library At present, we have achieved initial results in three aspects: the company's product standard formulation, the research and development of the structural parts standard library, and the research on the heat dissipation of LED full-color screens. The formulation of product standards is to define product standards, strictly control incoming materials and production, ensure that all products meet the company's quality requirements, and improve product quality. The research and development of the standard library of structural parts also improves the design efficiency of full-color LED display products, reduces the types of accessories, facilitates centralized procurement and stock preparation, and indirectly improves product competitiveness.

The introduction of inkjet process and bottom substrate process The introduction of these two processes has greatly improved the visual effect and anti-collision function of our rental LED full-color screen products. After we introduced the inkjet process, the ink difference of the PCB board was reduced and the color difference was improved. After introducing the bottom substrate process, the corners are better reinforced and the anti-collision function is increased. In other words, a better protective shell is provided for the quality of our LED full-color screen products.

Under the overall strategic plan of the screen, the LED full-color screen technical committee will continue to fill in the gaps in the company's original technology, overcome more difficulties, continuously optimize products, and provide customers with better products and services. I believe that the LED full-color screen technical committee can understand the latest technical information of the industry while collecting customer feedback, and combine the opinions of the two to make greater contributions to the company's LED full-color screen products and quality. .
