John Kymissis and Team Win IDW '21 Best Paper Award

January 18, 2022

The 28th International Display Workshops (IDW '21) took place virtually and brought together the world's electronic display industry. 

The paper "Improvement of Micro-LED Efficiency Through Optimization of Electrode Area and Device Geometry", written by John Kymissis, Keith Behrman and Vincent Lee, won the Best Paper Award.

MicroLED displays use LEDs which are patterned at the individual pixel level. In this paper, the researchers look at and quantify, the tradeoffs associated with several design choices made in microLED devices and propose a way to optimize performance, in particular, the size the pixels, the placement and size of the electrodes, and the current density of each pixel.  The researchers were able to both model the effects seen and experimentally demonstrate the predicted effects. 

"Since this was a virtual conference and a bit of an esoteric topic we were not entirely sure how the presentation would be received, but we were pleasantly surprised to get this award from IDW-MEET," Kymissis said.

A big congratulations to everyone involved!
