Samsung shows 75" and 219" Micro-LED displays at CES 2019

Samsung unveiled two new Micro-LED TVs at CES 2019. First up is the consumer model, a 75" Micro-LED TV that is made from tiled displays. We already reported on this TV in September 2018, and it is great to see Samsung manage to bring this display to CES - even if it is an early prototype.

Samsung did not reveal any details on this TV, or any plans to commercialize this technology soon. It would seem that when Samsung is ready, its Micro-LED TVs will be the company's flagship TV technology. It's current high end TVs use QD-enhanced LCDs (and the company is to be close to release a hybrid QD-OLED TV in 2019).

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.
