Micro-LED display technology is a new type of self-emissive display technology derived from the miniaturization and matrix arrangement of micro light-emitting diodes (LEDs). It is hailed as the "next-generation display technology" due to its advantages of high brightness, high contrast, high resolution, fast response, and low energy consumption. Micro-LED combines the strengths of LCD and OLED display technologies. Additionally, as it belongs to inorganic light-emitting diodes, it does not suffer from the lifespan constraints and screen burnout issues associated with OLED organic materials, making it a promising candidate for the "ultimate display technology" that could revolutionize the industry.
HMO (High Mobility Oxide) is a novel semiconductor material with an electron mobility 20 to 50 times higher than that of traditional amorphous silicon (a-Si) materials. It provides the screen with higher response speeds and lower power consumption, supporting ultra-high resolution while significantly enhancing pixel response speeds. HKC has been developing metal oxide technology since 2021. Through continuous exploration and experimentation, it has successfully developed second-generation oxides (HMO, High Mobility Oxide) with a mobility more than double that of the first generation.
As a leading enterprise in the display industry, HKC has pioneered the integration of Micro-LED display technology with HMO backplanes, successfully lighting up the industry's first 6.67-inch Micro-LED direct-view screen with a glass-based HMO backplane. Given that Micro-LED is a current-driven device, HKC has optimized the design of the HMO backplane to enhance the current-driving capability of Micro-LED and reduce power loss. This enables the screen to achieve a peak brightness of 1000 nits, a brightness uniformity of 95%, a contrast ratio exceeding 1,000,000:1, and 99% DCI-P3 wide color gamut coverage, delivering exceptional display performance in various environments.
Furthermore, the screen boasts a high pixel density of 100PPI, representing HKC's technological validation for large-size, seamless glass-based splicing display products. Currently, after years of development, the commercial large-screen display market has formed a mature upstream and downstream industrial chain, widely used in command and dispatch, surveillance and security systems, large indoor conference rooms, and other scenarios. However, due to production processes and technological limitations, LCD and OLED display technologies face numerous challenges in manufacturing screens larger than 120 inches, making it difficult to effectively meet the demands of commercial display screens. In contrast, HKC's independently developed modular glass-based Micro-LED splicing screens exhibit unique advantages. They not only inherit the characteristics of traditional screens, such as free splicing and infinite expansion, but are also more economical in terms of transportation and maintenance costs.
Micro-LED display technology is gradually emerging as a rising star in the high-end market, driving a comprehensive upgrade of the display market. HKC will deepen and broaden its research and development areas, explore the application scope of HMO backplanes in Micro-LED display technology, enhance display performance, and enrich human visual enjoyment.
