Switching Power Supply Trends: Efficiency and Intelligence Driving LED Display Future

Driven by the dual carbon goals and digital economic development, China's switching power supply industry is accelerating its evolution towards high-frequency operation, high power density, and intelligent control. The application of third-generation semiconductor materials such as gallium nitride (GaN) and silicon carbide (SiC) significantly enhances power supply efficiency and integration, providing core support for high-end applications.

Within the LED display sector, switching power supplies are increasingly prioritising high efficiency, energy conservation, and intelligent management. As Mini/Micro LED technology becomes more prevalent, displays demand greater power supply stability and current sharing uniformity, propelling power modules towards digitalisation and programmability. Intelligent power systems enable real-time monitoring of voltage and current, facilitating remote fault alerts and precise regulation to ensure long-term stable operation of large screens. Concurrently, high power density designs meet the evolving requirements for thinner, lighter, and higher-brightness LED displays.

China's switching power supply market is projected to exceed RMB 250 billion by 2025. As a key application scenario, LED displays will continue to benefit from technological innovation, ushering in a new era of more reliable and intelligent power supply solutions.
