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.

Metaphotonic OLED structure

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.

Hi Ron,

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?
