Seoul Viosys and Seoul Semiconductor showcase single-pixel RGB ‘Micro Clean LED’ enabling 42-220” 4K-resolution TV displays

South Korean LED maker Seoul Semiconductor Co Ltd and its ultraviolet (UV) LED product manufacturing subsidiary Seoul Viosys Co Ltd have showcased Micro Clean LED, a single-pixel RGB micro-LED technology that enables the design of 4K-resolution TVs with 42” to 220” displays. Unveiled at the Consumer Electronics Show (CES 2020) in Las Vegas in early January, the Micro Clean LEDs are ready for mass production.

Combining technology capabilities from Seoul Viosys – epitaxial growth of red, green and blue LED chips as well as proprietary mass transfer technology for single-pixel RGB µ-level chips – and Seoul Semiconductor – optimized surface-mount technology (SMT) to increase production capacity, and tiling technology for substrate connectivity – enables the production of customized display screen sizes.

Targeting the $100bn display market, micro-LEDs are said to deliver superior color rendering and optimal off-angle viewing compared with conventional LED/LCD technology. Also, unlike with organic light-emitting diiodes (OLEDs), micro-LEDs offer 1000x faster response time and up to a 30% reduction in internal/external power consumption, as well as infinite contrast range. In addition, display panels manufactured with micro-LEDs can be combined into larger displays. This modular approach means that display manufacturers can easily customize the size of their screens.

“The Micro Clean LED technology resolves several challenges in the manufacturing of micro-LEDs, which will bring cost reductions by combining three (RGB) LEDs in a single-pixel package, including transfer technology, consistent color mixing, and the ability to control individual color and light intensity,” says Seoul Viosys’ CEO Young Joo Lee.
