Plessey to integrate Nanoco's quantum-dots into its micro-LED displays
UK-based GaN-on-Si MicroLED developer Plessey Semiconductor announced a partnership with Quantum Dots developer Nanoco. Plessey aims to integrate Nanoco's cadmium-free quantum dots into its micro-LED displays.
Using a quantum-dot coating, Plessey will be able to use only blue micro-LEDs in its microdisplays, and convert the blue light to red and green to create full-color displays (in a similar way to today's QD-enhanced LCD displays). Plessey says that this design will enable it reduce its pixel pitch from 30 μm to just 4 μm, a reduction of 87%. The QD-enhanced micro-LEDs will also have a wide color gamut and will be more energy efficient compared to Plessey's current phosphor-based architecture.
