eMagin Corporation announced it was awarded a new patent by the U.S. Patent and Trademark Office (USPTO) for the company's Direct Patterning Display (dPd) technology.
The patent, No. 10,903,427, which relates to the apparatus and method for direct patterning of organic material using an electrostatic mask, follows two USPTO patents awarded last year and adds to eMagin's portfolio of 18 foundational dPd patents and utility applications for OLED patterning, processes and equipment.
"Our newest patent adds to our technological leadership in brilliant, full-color OLED displays for AR/VR," said Andrew Sculley, CEO of eMagin Corporation. "Display brightness is critical for both AR and VR devices and Heads Up Displays (HUDs) used in bright, daylight environments. Our proprietary dPd technology greatly enhances light output relative to competing products that require color filters with white OLED, which reduces the light output by approximately 80%. Our roadmap targets full-color displays in excess of 28,000 nits brightness by mid-2023, with an intermediate brightness of 10,000 nits later this year. This intermediate target brightness is approximately 20 times brighter than traditional full-color OLED microdisplays. Combining our roadmap for high brightness and the government funding we secured for equipment, we expect to enhance our technological edge and manufacturing capabilities to support our AR/VR customer needs."
The company's dPd technology enables the direct patterning of primary
RGB color OLED emitters enhancing light output at ultra-high resolutions.
Direct patterning also allows the use of highly efficient phosphorescent emitters, leading to a significant increase in brightness. The technology can incorporate improvements being developed in traditional white with color filter OLED microdisplays.
"In terms of brightness, our dPd technology is ahead today and we expect to stay ahead," Sculley said.
