2022 is approaching the middle of the year. In this half year, the LED display power supply industry is struggling.
The repeated epidemics in some areas have greatly restricted trade exchanges in various regions. The rise in raw materials has pushed up the cost of making LED display power supplies.
Coupled with the increase in the price of upstream chips, the market demand for LED displays has been suppressed, and the power supply industry has also slowed down. Some people say that this year is a year of innovation and research and development for power supply companies. In the future, the industry will launch many new products to welcome the new era! In order to promote the healthy development of the industry, “LED Screen Display World” selects power supply companies with certain representatives based on market performance.
