Plessey invited to speak at the Quantum Dot Forum 2019

14 March 2019

Plessey Semiconductors announced today that Clive Beech, microLED Applications Director, will present at the upcoming pre-conference workshop at the Quantum Dot Forum in San Diego on 19th March 2019, at 2:30 p.m. PDT. The event will be hosted by Smithers APEX from March 19th to 21st, 2019 at the San Diego La Jolla Marriot Hotel, San Diego, California.

The 2019 forum will feature two full days of programming focussed around lighting, display, and other emerging applications, material innovations, product trends, market drivers, and future opportunities within the quantum dots industry.

“We are delighted to have Plessey present at this year’s event. The forum provides a unique opportunity to learn from and network with a wide range of relevant companies within the industry. Clive’s presentation will give an overview of the application of quantum dot colour conversion to a monolithic GaN-on-Silicon microLED display.” said Ms. Ashli Speed, Conference Producer at Smithers. 

With typical pixel sizes of eight microns and sub-pixels at approximately four microns the application of quantum dot technology at this scale presents challenges of fabrication, conversion efficiency, stability under intense photo flux and environmental stability. Clive will be discussing possible approaches to solving these challenges.

“I am honoured to be invited to deliver a presentation at this year’s Quantum Dot Forum and look forward to sharing our progress with quantum dots in a microLED application as well as hearing about the great work other companies within the industry are doing” said Clive Beech, microLED Applications Director at Plessey.

Quantum dot technology applied to microLED pixels enables the production of small, higher-resolution displays for applications such as AR/VR, watches and mobile devices with excellent colour rendition and colour conversion efficiency. For pixels of 30 µm or greater, colour conversion of the native blue emission is currently performed by using phosphors. However, because the smallest phosphor particles are about 30 µm, the efficiency of colour conversion deteriorates as the pixel size shrinks. Quantum dot technology overcomes this limitation while facilitating efficient conversion with close pixel packing.

Plessey was recently named as a ‘CES 2019 Innovation Awards Winner’.

The presentation by Clive Beech will take place at 2.30pm on Tuesday, March 19, 2019. To arrange a meeting, please contact:
