As China becomes a superpower, it is also gradually implementing industrial transformation and has put forward the slogans of "Intelligent Manufacturing in China" and "Scientific and Technological Self-reliance". In 2021, the convening of the Two Sessions and the 14th Five-Year Plan have brought new development opportunities to the LED industry. Major policies and development trends such as 5G+8K, new infrastructure, promoting smart city construction, and accelerating the development of digital cultural tourism have ushered in a huge blue ocean market for the entire LED display industry. At the same time, the new development pattern is dominated by the domestic cycle, and domestic market demand is gradually expanding.
Lianjian Optoelectronics ("United Microelectronics" for short) positions itself as a "trustworthy large-screen supplier", and its product quality has long been recognized by customers. Faced with the most troublesome problems for customers, such as black screens, "caterpillars", insufficient flatness, and insufficient purity, Lianjian Optoelectronics has been doing its best We have conquered and set quality standards that are higher than the industry, and serve customers with five "heart" quality and ingenuity. Even customers from Japan, the United States, Germany and other countries who have extremely high product quality requirements will still choose UMC products as their first choice. This is customers' trust in our quality.
01
Quality and craftsmanship
LianTronics
Since its establishment, LianTronics has attached great importance to the quality of its products. UMC is one of the first LED large screen manufacturing companies in the industry to pass the national military standard system certification. It has successively obtained safety production licenses, steel structure construction qualifications, and system integration qualifications. It has various authoritative certifications including quality management systems, and its product quality maintains a leading position in the industry.
+ + Strong comprehensive strength has made Lianjian Optoelectronics the preferred brand for Fortune 500 companies such as Sinopec, PetroChina, Tencent, Alibaba, and Huawei; it is also the leading trusted brand in the field of military-grade display and control such as the Central Military Commission and major military regions; it has provided global display services for international events such as the Brazilian World Cup, the American NBA, and the Guangzhou Asian Games; and has also created many classic cases in global landmarks such as the Egyptian Pyramids, Beijing Daxing International Airport, and Chengdu Taikoo Li Business District.
+ + Quality needs to be achieved through talents, systems, and processes, so Lianjian Optoelectronics has always attached great importance to the construction of the underlying architecture, that is, scientific and systematic management. Strictly following the system construction, Lianjian Optoelectronics has gained rich and valuable management experience so far, and cultivated a large number of talents with ingenuity, using practical actions to respond to the "craftsman spirit" mentioned many times in the government work report of our country.
China’s LED industry is already leading the world. As the first echelon in the industry, UMC has always believed that “obtaining long-term corporate development through product quality” is the goal we should pursue. Therefore, UMC people actively learn and inherit the spirit of craftsmanship. Through training many personnel in intelligent manufacturing technical positions, we build a “master craftsman” system, which plays a role of mentoring and mentoring. The craftsmanship spirit of excellence is integrated into the blood of UMC people, and quality confidence is precipitated and stabilized in the hearts of every craftsman.
02
Careful use of raw materials
LianTronics
We consistently adhere to quality from corporate strategy to national level. The first step to insisting on quality is of course inseparable from the selection of raw materials. In terms of main material selection, UMC's six main materials, including luminous LED lamps, driver chips, switching power supply PCBs, high-protection boxes, and connectors, are carefully selected from the top three quality suppliers in the field of suppliers, most of which are listed companies.
During the testing phase of incoming materials, we will conduct strict screening to ensure that the parameters of each raw material are within a constant range, adhere to high standards for material selection, and lay a solid foundation for the final high-quality product. We have put forward higher standards for testing equipment and testing standards. For example, in the LED lamp inspection process, the equipment testing accuracy reaches 0.01mcd, and the brightness uniformity must be less than 1:1.1 to ensure that our final display consistency is better; our die-cast box inspection, bottom shell, and mask inspection are based on the measurement of the dimensions, flatness, point spacing, hole spacing, etc. The detection accuracy can reach 0.005mm, and the process gap is less than 0.01mm, so that the pixel center distance The deviation is less than 4%, and the zero-stitching effect is truly achieved with a precision higher than the industry standard. This is also conducive to making various shapes, so that the design effect and the real-life effect are 100% highly restored; the power supply is a consumable part, and its quality has a great impact on the quality of the LED screen. Our LED screens often face different environmental challenges, especially outdoor screens. Harsh temperature and humidity, wind and sand, extreme heat, severe cold, etc. all have very high requirements on the power supply. We will use switching power supply testing equipment
17 data tests were conducted on the safety performance, electrical performance, and reliability of the power supply to ensure that the power supply can meet electrical performance while also adapting to various environmental changes.
Our supplier once said with a smile: "For all products of the same batch that have passed Lianjian Optoelectronics' inspection, other LED display companies have said that they can be used directly without re-inspection." This is enough to show that Lianjian Optoelectronics is almost "paranoid" and harsh in the selection of suppliers and raw materials.
Lianjian Optoelectronics is willing to select suppliers with consistent values and use strict management to monitor and audit them. In addition, it will actively help suppliers analyze problems and meet standards. Not only does it help suppliers sort out quality control standards and processes, it also improves testing standards and strengthens the incoming material testing process. Only by analyzing and solving problems with our suppliers, taking responsibility together, and growing together can we fundamentally solve the problem of raw materials and maintain the quality of our raw materials stably in the long term.

Detect safety
LianTronics
Since the beginning of this year, the market environment is picking up, and company orders are coming one after another. While everyone is focusing on how to obtain more orders and how to quickly seize the market, the company's senior management is focusing on product quality. The harvest of a large number of orders is a double-edged sword, which not only improves performance, but also increases the load on the production process. Without sufficient introspection, quality problems will appear sooner or later.
To this end, Lianjian Optoelectronics has accelerated the innovation of its own testing links and created the Lianjian Optoelectronics product quality grading method. The products are divided into five levels from the three aspects of flatness, purity and reliability that customers are most concerned about and can feel the difference most. The qualification standard is set above the industry standards, which means that our product testing can reach the minimum industry standards and can be higher than the industry standards. This is the spirit of Lianjian Optoelectronics’ continuous pursuit of self-transcendence in quality.
Lianjian Optoelectronics has a complete quality management system and a mature and standard inspection process in the inspection process, which is higher than industry standards and military-grade quality. Our production process has a total of more than 70 testing procedures and more than 400 testing items. All products have been 100% aged for more than 72 hours to ensure that the products are used well to the limit. We also conduct 55 re-inspection tests on all environments of the finished products before shipment to ensure that the qualified rate of shipped finished products is 100%!
04
Technological Innovation
LianTronics
Technological innovation not only stems from LMC’s positioning as a “trustworthy large-screen supplier” but also from our “customer-centric” belief. Meeting and exceeding customer expectations is part of LMC’s quality. And good quality requires technical support. Lianjian Optoelectronics has long been committed to the two key points of quality and innovation. So far, it has 10 first-of-its-kind patented technologies and 43 black technologies. Multiple innovative researches have placed LED product technology at the forefront of the industry. For example, Lianjian Optoelectronics has independently developed patented equipment for automatic ink color detection and has continuously upgraded it; the industry's first five-axis three-dimensional finishing technology, leading the industry in accuracy; the first six-way fine-tuning technology to achieve a smooth, mirror-like patchwork effect on the LED screen; and the first dual backup non-black screen technology to achieve stable operation without black screen for a long time.
In addition, Lianjian Optoelectronics’ production base also has many other high-end intelligent equipment to ensure high-quality production of products. For example, our SPI fully automatic 3D solder paste inspection machine can 100% ensure that the product will not be defective due to no solder or less tin; AOI automatic optical inspection equipment can detect common defects in the welding production process, which can greatly improve production efficiency and welding quality. , the equipment covers international first-line brands such as Yamaha, Panasonic, Fuji, etc., with a production qualification rate as high as 99.8%; it also has Japanese CNC punch machines, Swedish and German three-dimensional coordinate measuring machines, American Universal plug-in machines, Japanese Fuji placement machines, patented intelligent EFI and other automation equipment.
Cutting-edge equipment and technology keep Lianjian Optoelectronics’ production technology at the forefront of the industry. A major overseas customer once commented that we are a "German company in China". You must know that German craftsmanship has always been synonymous with high quality, which is enough to show that customers affirm our craftsmanship and technology.

We provide one-stop service for the whole process, from design to production, from installation and construction to final delivery. Every link is professional, rigorous, meticulous and considerate. We not only hand over the products to the customers, but also continue to provide training and after-sales service to ensure the good operation of the products. We deliver not only products, but also services.
+ + Lianjian Optoelectronics Engineering Team has more than 100 engineers, with an average of more than 8 years of project experience, and their certified skills are guaranteed. In addition to professional personnel, in project construction management, we can be professional and reliable in the three stages of construction: in the construction preparation stage, we implement start-up report description, plan material review, and technical quality disclosure management; construction site assurance quality inspection plan formulation, on-site measurement, regular spot inspections, and process inspection execution records; during the construction process, we implement project self-inspection, completed project acceptance, and delivery data review and storage; in the after-sales stage, UMC promises to provide 24/7 response services at any time during the product warranty period.
From raw material testing to product delivery, Lianjian Optoelectronics strives for excellence in every aspect of the entire process. Adhering to the craftsmanship spirit of high requirements and high quality will inevitably increase costs. On the surface, it seems that the company will suffer losses. However, only by first allowing customers to gain a sense of high value brought by high quality can the level of the entire industry be improved and customers have more choices. Lianjian Optoelectronics not only wants to be a Chinese smart manufacturing brand with independent technology, but also a "trustworthy large-screen supplier" with quality and ingenuity, and is committed to making first-class products!
