Recently, HKC achieved a major breakthrough in the high-end display sector by successfully completing the development of the world’s first silicon-based GaN single-chip integrated full-color Micro-LED chip (SiMiP) for micro-pitch LED displays. This technology was co-developed with LEKIN Semiconductor and enhances both production efficiency and display performance. It offers the industry a more competitive solution while positioning China at the forefront of micro-pitch LED display technology.
I. Technological Innovation: The Path to Breakthroughs in Direct-View Displays
With the rapid development of micro-pitch LED displays, the demand for smaller chips in COB products has surged alongside the shrinking pixel pitch. The MiP solution has become the ideal choice for the next generation of micro-pitch direct-view display technology.
Thanks to years of technological expertise and industrialization experience, HKC successfully integrated the core advantages of both LEKIN Semiconductor and its own display solutions and supply chain resources. This collaboration has led to the successful application of the SiMiP chip. The newly developed SiMiP technology integrates the red, green, and blue sub-pixels into a single chip, simplifying production and repair processes. This innovation significantly increases production yield and reduces manufacturing costs, offering both high performance and cost efficiency to drive the revolution and widespread adoption of micro-pitch LED display technology.
II. Core Advantages of SiMiP
- Simplified Process and Improved Yield: By adopting a single-chip integration solution, complex mass transfer and repair processes are eliminated, resulting in a substantial improvement in yield.
- Cost Optimization and Environmental Upgrades: The innovative technology reduces complex steps in traditional processes while avoiding the use of toxic materials, offering significant environmental advantages.
- Exceptional Performance and High Consistency: The RGB sub-pixels in the SiMiP chip exhibit high consistency in light emission wavelength, operating voltage, and light distribution, solving the color deviation problem common in traditional solutions.
III. Technology-Driven Leadership in High-End Displays
As a leader in the display industry, HKC is committed to driving industry upgrades through technological innovation. In recent years, HKC has consistently increased investment in Mini/Micro-LED technology development and production capacity, with total investments surpassing 10 billion RMB (approximately $1.55 billion USD). This has enabled the company to establish a complete ecosystem from technology research and development to large-scale production.
The successful application of SiMiP chip technology further solidifies HKC’s leadership position in the high-end display sector. Moving forward, HKC will continue to strengthen its technological footprint, further advancing the innovation and adoption of small-pitch LED direct-view display technology. The company aims to provide high-quality, efficient display solutions to global customers and lead the rise of “smart” manufacturing in China’s global display industry.
