Lordin, an OLED startup founded in 2020, has developed a blue OLED with an IQE of 90%. It has si far registered 4 patents and plans to file 19 more. The company’s CEO, Oh Hyoung-yun told The Elec, the company was planning on commercializing its technology in 2024.
Lordin’s technique for manufacturing blue OLEDs relies on the concept of zero-radius energy transfer, whereby the transfer of energy between donor and acceptors in materials is highly efficient as a result of the overlap of their wave functions. One example of where this energy transfer efficiency is used is in solar cells called luminescent solar concentrators (LSCs) where you want rapid transfers of energy and very high efficiencies. Lordin has developed the blue OLED dopant and eschews the thermally activated delayed fluorescence (TADF) modes adopted in blue OLED technologies like those from UDC and Samsung.
It’s going to be an uphill battle of Lordin to some extents because there is a body of research on TADF blue OLED materials, and ways to improve efficiencies. That means the big boys are not going to be beat on feature set for their solutions. So, this may be a lot of noise on the part of Lordin, hoping to get noticed in a challenging market or it may be a play to push an IP licensing model at some point when it is ready in 2024 or just marketing through repetition because the company has been singing this tune since day one.
