In 2020, the “black swan” of the new crown epidemic disrupted the originally peaceful world. Offline social interactions are suspended, schools are suspended, and industries are suspended. Every aspect of people’s social life has been disrupted by this “black swan”. Among them, the global economy has suffered heavy losses, and the LED display application industry is inevitably implicated. Under the new development pattern of domestic and international dual cycles, LED display related companies quickly adjusted their strategies in terms of products and channels, and actively responded to the new normal of the epidemic.
Looking back on 2020, according to relevant agency data, the total global LED market value in 2020 is about 15.127 billion U.S. dollars (about 98.749 billion yuan), a year-on-year decrease of about 10.2%; the LED wafer market capacity is about 28.846 million pieces, a year-on-year decrease of about 5.7 %. Among them, the annual output value of my country’s LED display application industry is expected to drop by about 18%, reaching 35.5 billion yuan.
Judging from the performance of my country’s six major listed LED display companies, due to the epidemic and other factors, the operating income and net profit of LED display companies in the first three quarters have declined compared with the same period in 2019. The largest decline is Lianjian photoelectric. However, as far as 2020 is concerned, operating income and net profit have both increased in the third quarter, and it is expected that the increase in the fourth quarter will be even greater.
In a special period, the leading companies have demonstrated their unique strengths. New products and new businesses have gathered to the leading companies. The role of the brand has gradually become prominent, and the stronger the stronger. Among the six listed LED display companies, although the growth rate in the first three quarters has not been as good as before, except for a loss of 158 million yuan in Lianjian Optoelectronics, the rest of the companies have made profits.
As a growing industry, the development of the LED display application industry mainly depends on the progress of LED display technology, the introduction of new products and the quality of services. Although the epidemic has hit the market tremendously, the fundamentals of the industry have remained stable and the overall trend is improving.
Although the epidemic crisis has not been completely resolved, my country’s economy is gradually recovering, and the LED display application industry is also making steady progress. In 2020, China’s LED display industry will be mixed by the dual influence of the new crown epidemic and the international environment. The good news is that the in-depth cultivation process in the fields of small pitch, Micro/Mini LED and high-definition video industries is gratifying, and the development space in various market segments is expanding. The worry is that the epidemic has caused a “broken chain” crisis in the supply chain. And chip prices fluctuate and delivery time is elongated.
Connect more end users
What are the growth drivers of the first-tier market in 2021, and what are the methods and means for manufacturers to seek growth? It is the top priority of all LED display manufacturers. At present, the development trend of the entire industry is the giant and oligopolistic stock market competition. The only growth driver in the market actually comes from end users. Who can take the lead in connecting more end users, who can break through the predicament, and this requires LED display manufacturers to take the lead in completing the optimization and upgrading of channels.
After the “tempering” of the 2020 epidemic, the channel of the LED display industry is no longer a simple “offline channel to win”. Many LED display companies have cultivated, developed and consolidated the channel moat and offline dealer system for many years. We are facing new adjustments-online and offline integration has become a reality.
However, for many traditional LED display distributors, how to better integrate online channels while maintaining stable offline performance and sustainable operation, and achieve upgrades in store purchase experience and after-sales service. For upstream manufacturers, how to ensure the stability and sustainability of dealer groups in the context of channel fragmentation and multi-polarization is also a major challenge.
Product adjustment and detonation
In the past two years, all kinds of new products in the LED display market have experienced a round of “high driving and low going” multi-vibration pattern. To put it simply, a round of high-end transformation is like a passing cloud and rain, and soon no sound; a round of low-priced high-quality products, a large number of products under the banner of high cost performance, has won the attention of a group of users.
In the current situation of diversified consumption, products are not just simple technical iterations and functional innovations, but a step toward scene-oriented. It is to provide good products that they really need according to the needs of users of different levels, different needs, and different income groups, not just low prices. The test is not technological innovation, but the grasp of comprehensive strength. Therefore, how to enable the iteration and innovation of LED display products through scenarioization in 2021, whether it is stimulating stock replacement or stimulating new demand, will test the R&D and innovation capabilities of many LED screen companies.
Brand further stratification and positioning
Full-category, multi-brand hierarchical, differentiated management, this is the current standardized operation of many LED display manufacturers. Mainly in order to face the continuous differentiation of mainstream consumer groups in the market in recent years, the most representative one is that the circle of interest has become more professional and more subdivided.
If we say that the layout of the whole category is to respond to the current needs of many consumers for complete sets and integration, and to enjoy a more convenient and efficient product experience. The segmentation of so many brands is to find customer segmentation needs of different levels, different economic levels, and different product pursuits. Therefore, how to find target users and how to achieve precise product promotion and marketing. These challenges directly determine the implementation capabilities of many manufacturers in 2021.
The Eastern Olympics brings new opportunities
China’s LED products were first known to the world at the 2008 Beijing Olympic Games and have been popular all over the world ever since.
