Researchers from Stanford university in collaboration with Samsung's Advanced Institute of Technology (SAIT) developed a new OLED structure that enables resolution of up to 10,000 PPI, high brightness and a cost-effective production process.
In the new so-called Metaphotonic OLED structure, the panel is produced on a base layer of reflective metal with nanoscale corrugations. This 'metasurface' can manipulate the reflective properties of light and thereby allow different colors to resonate in the OLED sub-pixels.
This new design offers a completely different OLED color architecture -where one of the main advantages is the fact that all OLED sub-pixels are produced in the same height which means other material deposition is easier.
Samsung's research team is now working to integrate this work into a full-sized OLED display.
Hello Michael, here's the link to the original paper: Won-Jae Joo et al, Metasurface-driven OLED displays beyond 10,000 pixels per inch, Science 23 Oct 2020: Vol. 370, Issue 6515, pp. 459-463 DOI: 10.1126/science.abc8530 , science.sciencemag.org/cgi/doi … 1126/science.abc8530
do you have further info, e.g. a paper being published or press release?
Do you know, which group in Stanford is working on the program?
