NationStar has recently achieved significant progress in Micro LED technology by developing a highly consistent pixelated quantum dot color conversion film. This innovation reduces the number of mass transfer steps by two-thirds, addressing critical issues like low yield and efficiency of red Micro LED chips and the high complexity of mass transfer. This breakthrough enhances yield, minimizes repair needs, lowers costs, and provides new momentum for the industrialization of Micro LED technology.
Breaking Through Barriers: Advancing Micro LED Industrialization
In recent years, Micro LED display technology has made rapid strides due to its exceptional benefits. However, obstacles like technological immaturity and high costs have hindered its large-scale commercialization. Quantum dot color conversion technology offers a key solution for Mini/Micro LED, OLED, and LCD wide color gamut displays. Compared to traditional RGB display methods, quantum dot technology simplifies circuit design and reduces transfer complexity, enabling lower power consumption and higher yields. This makes it a promising approach for achieving high-resolution, full-color Micro LED displays and positions it as a frontrunner for Micro LED commercialization.
Building on this, NationStar has developed a Quantum Dot Color Converter (QDCC) film that efficiently converts high-energy blue light into red and green light, significantly boosting display performance in terms of color gamut coverage, color accuracy, and the purity of red and green hues. The company has also produced highly consistent quantum dot color conversion films with different pixel arrangements, pushing the boundaries of Micro LED technology.
By integrating QDCC with a high-density Micro LED blue chip array, NationStar has successfully developed high-quality full-color LED displays. This advancement opens up potential applications in ultra-high-definition (UHD) fields, including smartwatches, commercial monitors, and large-scale displays.
Leading the Industry: NationStar Expands Its Reach
China’s 14th Five-Year Plan provides strategic support for the growth and advancement of the country’s new display industries. With the rapid development of “5G+8K” technologies, a new wave of visual revolution is emerging, and strategic frameworks centered around next-generation display technologies like Mini/Micro LED are quickly forming.
As a leader in LED packaging technology, NationStar has been at the forefront since establishing China’s first Micro & Mini LED Research Center in 2018. The company has consistently focused on overcoming the technical challenges of Mini/Micro LED and advancing its industrialization. To date, NationStar has achieved breakthroughs in several key Micro LED technologies, developed proprietary processes, and secured numerous intellectual property rights. The new high-consistency pixelated quantum dot color conversion film technology further strengthens NationStar’s position in the UHD Micro LED display industry, solidifying its leadership in cutting-edge technologies and enhancing its core competitiveness.
Future Outlook: Continuing the Innovation Journey
Looking ahead, NationStar will continue its innovation-driven development strategy, actively positioning itself in the new micro-display sector. The company remains committed to tackling common industry-wide technical challenges in Micro LED technology and advancing its commercialization.
