Seoul Semiconductor and Seoul Viosys Showcase Micro LED Enabling 4K TV from 42 to 220-inch at CES 2020

Seoul Semiconductor and Seoul Viosys announced that they are introducing the new concept display, ‘Micro Clean LED’ at CES 2020.

The new concept of Micro Clean LED, which Seoul Viosys developed, is the technology that realizes 4K resolution TV sizes from 42 inch to 220 inch with 1 RGB LED per pixel and is ready for mass production. The Micro Clean LED solutions for a smart watch display also will be demonstrated at CES 2020.

Seoul Semiconductor and Seoul Viosys leverage their expertise in developing the Micro LED display with their in-house technologies. Seoul Viosys worked on MOCVD for EPI growth of RGB colors and mass transfer solution for the chips. Seoul Semiconductor possesses the tiling technology, substrate connectivity technology, for large-screen display by preparing SMT, surface mounted technology and manufacturing process at the customer’s request.

Furthermore, since it is developed as 1 pixel, it resolves three main challenges for Micro LED including transfer technology, color mixing and individual color and intensity of light control. By resolving these three challenges, Seoul claimed that it has reduced the cost by one third and the product reliability test is also completed.
