Plessey and Jasper Display partner on monolithic microLED displays

September 11, 2018 // By Julien Happich
GaN-on-Si wafers and LED solutions provider Plessey Semiconductors has struck a strategic partnership with Jasper Display Corp (JDC) to integrate the Taiwanese company's silicon backplane with its own monolithic microLED displays manufactured on proprietary GaN-on-Silicon (GaN-on-Si) wafers.

Earlier this year, JDC had unveiled the eSP70, a silicon backplane tailored to drive microLED devices. The full colour capable active matrix backplane features a resolution of 1920x1080, a pixel pitch of 8µm and offers excellent current uniformity via a proprietary current source pixel as well as flexible addressing. By utilising JDC’s eSP70 backplane, Plessey hopes to leverage its GaN-on-Si platform and deliver very high brightness microLEDs with moderate power consumption or run with low power while maintaining daylight usable brightness levels.

“JDC’s microLED specific silicon backplane allows Plessey to rapidly bring to market our monolithic full colour microLED array at our entry level 8µm pixel size. At Plessey, we have overcome the significant challenges involved in accurately aligning and bonding the microLED array with the backplane. We are looking forward to partnering with JDC as we continue our development, reducing pixel and display size”, said Dr Keith Strickland, Chief Technology Officer at Plessey in a company statement.
