Micro LED display technology is a new type of self-emissive display technology obtained by miniaturizing and matrixing micro-light-emitting diodes (LEDs). It is hailed as the "next-generation display technology" due to its advantages such as high brightness, high contrast ratio, high resolution, fast response, and low energy consumption. Micro LED combines the advantages of LCD and OLED display technologies. Furthermore, because it is an inorganic light-emitting diode, it does not suffer from the lifespan limitations and burn-in issues associated with OLED organic materials, and is expected to be the "ultimate display technology" that will revolutionize the industry.
HMO (High Mobility Oxide) is a novel semiconductor material with electron mobility 20 to 50 times that of traditional amorphous silicon (a-Si). This allows for higher response times and lower power consumption in displays, supporting ultra-high resolution while significantly improving pixel response speed. HKC has been developing metal oxide technology since 2021 and has successfully developed second-generation oxides (HMOs), whose mobility is more than twice that of the first generation.

HKC has successfully combined Micro LED display technology with an HMO backplane to illuminate the industry's first 6.67-inch Micro LED direct-view screen with a glass-based HMO backplane. Recognizing that Micro LEDs are current-driven devices, HKC optimized the HMO backplane design to enhance the current-driving capability of Micro LEDs and reduce power loss. This results in a screen with a peak brightness of 1000 nits, 95% brightness uniformity, a contrast ratio exceeding 1,000,000:1, and 99% DCI-P3 wide color gamut coverage, delivering outstanding display performance in various environments.
Furthermore, the screen boasts a high pixel density of 100 PPI, representing a technological validation achievement for HKC's large-size glass-based seamless splicing screen products. Currently, the commercial large-screen display market has developed a mature upstream and downstream industry chain after years of growth, and is widely used in various scenarios such as command and dispatch, monitoring and security systems, and large indoor conference rooms.
