On March 21, Radeon announced the launch of the PowerMatch® 1 full-color Micro-LED light engine, which has a volume of only 0.18cc, setting a new record for the smallest full-color light engine.
As explained, due to the limitations of single-chip full-color Micro LED technology, current full-color light engines on the market use a three-color combining scheme, which optically combines red, green, and blue monochromatic screens, with a volume of approximately 0.4cc. However, due to limitations in cost, size, and issues such as the luminous efficacy and thermal stability of native red light, this scheme is destined to remain only a transitional option.
Raex has launched a full-color light engine equipped with its 0.13-inch PowerMatch® 1 full-color microdisplay. With a volume of only 0.18cc (45% of the volume of a three-color light-combining solution) and a weight of only 0.5g, it can be seamlessly integrated into the temples, making AR glasses thinner and lighter, thus improving comfort. This is a significant advantage for AR glasses used for extended periods.

Radeon's independently developed quantum dot lithography technology combines high luminous efficiency and high resolution, employing standard semiconductor processes to achieve fine sub-pixel patterns, providing a feasible mass production solution for full-color Micro LED microdisplays. Simultaneously, by incorporating optimized luminescent materials, color-driven algorithms, crosstalk elimination technology, and contrast enhancement technology, the PowerMatch® 1 series achieves a 108.5% DCI-P3 wide color gamut and high color purity, presenting a delicate and rich image effect.
In addition, the PowerMatch® 1 series achieves a significant increase in brightness while maintaining low power consumption. Currently, the brightness of the microdisplay has been increased to 500,000 nits (under white balance), which can provide 0.5lm of luminous flux output for the full-color light engine. Moreover, this new technology architecture still has great potential for performance improvement, opening up more possibilities for AR to break through scene limitations.
According to available information, Radeon Semiconductor, founded in 2019, is a high-tech company specializing in Micro LED microdisplay chip architecture design, manufacturing processes, and single-chip full-color technology research. The company's core team originates from the Department of Electronic Engineering at the Hong Kong University of Science and Technology, possessing many years of experience in cutting-edge optical chip design and manufacturing. Currently, Radeon has sent samples to several downstream customers and begun prototype collaborations.
