X Display Company (XDC), a developer of semiconductor devices for displays, and Lumileds, a developer of MicroLED technology, have developed a revolutionary 140 pixels per inch (ppi) microIC-driven microLED prototype display. This first of a kind display technology marks a significant milestone for MicroLED displays in mobile consumer applications including smartwatches, smartphones, tablets, and PCs. MicroICs enable a significantly more flexible and power efficient approach to display backplane architecture.
“We see a lot of potential for MicroLED displays in mobile consumer electronic devices,” said Ross Young, CEO of DSCC. “This XDC and Lumileds breakthrough will improve the cost, power, and brightness display profile significantly as to help accelerate adoption of these technologies.”
The new MicroLED display features a cost-effective and power-advantaged architecture that leverages a cluster drive system combined with MicroLEDs that measure just 13×20 µm². The result is a peak brightness of 2360 cd/m² that offers an unparalleled viewing experience with stunning clarity, color, and contrast. Both the microICs and microLEDs are manufactured using cutting-edge production equipment that ensures industry-leading uniformity and yield rates. Notably, the mass transfer process employed in the development of these prototypes achieves an impressive 99.9998% microLED sub-pixel yield and a 99.992% microIC transfer yield. The processes used to manufacture the prototype are mass production ready.
“XDC’s mass transfer, bonding, and display driving technologies have created new opportunities to transform the world of displays,” said Brendan Moran, Sr Director of Display Technology at Lumileds. “Lumileds has successfully implemented XDC’s transfer-ready microLED technology into our volume production LED fabrication facilities. Together, we are setting new standards in the microLED industry and advancing mobile display technology.”
“This milestone is made possible by Lumileds’s device expertise and manufacturing process discipline applied from the very start. The result is repeatable, high-quality microLED displays,” said Matt Meitl, EVP and co-founder of XDC. “Our long collaboration has resulted in microLED displays sought by customers in the mobile device space.”
XDC and Lumileds are pleased to announce that the microICs, microLEDs, and the advanced transfer equipment utilized in this prototype can be deployed for interested customers, paving the way for broader adoption of this technology in mobile consumer devices.
