Researchers develop the highest-performance solution-processed transistors for microLED displays

Researchers from the University of Illinois Urbana-Champaign developed a new process to create transistors for high-performance microLED displays. The researchers say that this is the highest performing solution-processed semiconductor transistor to date, and a potential low-cost one.

The new method is based on ordered defect compound semiconductor CuIn5Se8 prepared by solution deposition. These transistors were used to form high-speed logic circuits operating in megahertz, to power a small 508 PPI blue microLED display (8 micron LEDs).

Interestingly, the researchers discovered that the best semiconductor for this process has higher defect concentrations than its parent material.
