eMagin awarded four additional patents for direct patterning OLED microdisplay technology

 

eMagin Corporation (Hopewell Junction, New York), a leader in the development, design and manufacture of high-resolution OLED microdisplays for AR/VR and other near-eye imaging products, has been awarded four additional patents by the U.S. Patent and Trademark Office (USPTO) for the company’s Direct Patterning Display (dPd) technology. The patents relate to the creation of high-resolution displays with unique pixel structures and proprietary fabrication methods, and bring to 21 the company’s total number of foundational, dPd-related patents and utility applications for OLED patterning, processes and equipment.

“Our latest patents strengthen our IP protection for pixel structures and fabrication methods that we expect will be the fundamental building blocks for displays in the next generation of AR and VR headsets,” said Andrew Sculley, CEO of eMagin Corporation. “High brightness is required not only for AR, but also for VR applications to eliminate motion artifacts and compensate for low optics efficiency. Additionally, the inherent improvement in efficiency in a high-brightness display allows for longer device lifetime.”

The four patents relate to the physical deposition of organic semiconductor materials on a substrate with very high resolution and precision for microdisplay applications. eMagin’s dPd technology enables the direct patterning of primary RGB colour OLED emitters to enhance light output at ultra-high resolutions. Direct patterning also allows for the use of highly efficient phosphorescent emitters, leading to a significant increase in brightness. Through the use of tandem architecture and other enhancement techniques that are typically used in white OLED with colour filters, eMagin can further scale the brightness of its OLED microdisplays.
