Over the past two decades, China has evolved from a latecomer to a global leader in the LED industry, building a complete industrial chain covering upstream chips, midstream packaging and downstream applications. Driven by national dual-carbon policies, urbanization and technological breakthroughs, China’s LED market scale exceeded 600 billion yuan in 2023, with a penetration rate of over 80%, accounting for more than 65% of the global LED chip production capacity and leading the world in packaging and application scale5. This rapid development has been supported by continuous technological iterations and the rising role of key materials such as LED phosphors, with enterprises like Shenzhen Mengzhi Technology making remarkable contributions to the advancement of the industry.
Future Trends and Innovations
Looking ahead to the next decade, China’s LED industry will usher in a new round of technological innovation centered on intelligence, miniaturization and high efficiency. Mini LED and Micro LED technologies will achieve large-scale commercialization, with Micro LED expected to break through mass transfer bottlenecks and become a disruptive force in the display and lighting fields by 20366. Smart lighting, integrated with the Internet of Things and artificial intelligence, will realize scenario-based light adjustment, while healthy lighting with full-spectrum LED phosphors will become mainstream in homes, offices and medical institutions, effectively relieving visual fatigue. Additionally, the application of LED in emerging fields such as automotive lighting, plant lighting and data center optical interconnection (CPO) will open up new growth engines, driven by the demand for energy conservation and high performance.
The Pivotal Role of LED Phosphors
LED phosphors, as the core material determining the color performance and luminous efficiency of LED products, play an irreplaceable role in backlighting, lighting and display. In the backlighting field, high-performance LED phosphors such as fluoride red powder can increase the color gamut of LCD displays from 72% NTSC to over 90%, delivering more vivid and realistic colors for TVs, computer monitors and mobile screens. Shenzhen Mengzhi Technology, a key enterprise focusing on LED phosphor R&D and production, has developed high-light-conversion-efficiency phosphors with a luminous efficiency of 140-200 lm/W, which are widely used in SMD packaging and backlight modules, enhancing the competitiveness of China’s backlight industry in the global market.
In lighting applications, LED phosphors have promoted the transformation of traditional lighting to energy-saving and high-quality lighting. High-purity LED phosphors can adjust color temperature between 3000K and 6500K, meeting the needs of different scenarios from warm home lighting to bright industrial lighting. They also improve the color rendering index (CRI) to over 85, ensuring accurate color reproduction, which is crucial for medical and commercial lighting. In the display field, LED phosphors cooperate with Mini/Micro LED chips to achieve higher brightness and contrast, promoting the popularization of 8K ultra-high-definition displays and XR virtual shooting technology6.
Conclusion and Future Outlook
With continuous technological investment and policy support, China’s LED industry will maintain its leading position in the global market in the next decade. LED phosphors will continue to iterate towards higher efficiency, better stability and lower cost, with enterprises like Shenzhen Mengzhi Technology leading the R&D of environmentally friendly, lead-free phosphors compliant with RoHS standards. The integration of LED technology with emerging industries will not only drive the upgrading of the optoelectronic industry but also make important contributions to global energy conservation and carbon reduction goals.
