What They Say
We were digging around about microLEDs when we stumbled on this article from a couple of months ago, that describes how a Korean company, Tetos, is supplying technology to connect together the modules used in Samsung’s microLED TVs along the edges of the modules. 49 modules 12.7″ modules are used in an 89″ and 64 are used in the 101″. Samsung display makes the glass substrates, with TFTs, then Tetos adds interconnects using a ‘self-developed three-dimensional sputtering method’.
Woo-young Ahn, CEO of TETOS, said,
“If the sputtering method is used, even if dozens or hundreds of MicroLED cell glass substrates are connected, there is no gap between the substrates. MicroLED TV can be freely expanded in size and shape.”
The report said that 15,000 modules would be supplied in July, but the volume is expected to reach 100,000 by 2023.
Tetos is planning to apply for a listing on the Kosdaq market in the second half of the year. The firm was founded in 2010.
What We Think
Making seamless joints between the modules is tricky even without the interconnects! I remember seeing an earlyish microLED Wall TV from Samsung at IFA and the modules really were obvious. That’s acceptable in some applications, but not, I thought, in a €100K+ TV! Tetos is clearly an interesting company, so I’ll keep my eyes peeled for more news. (BR)
