EMagin, which specializes in the development, design and manufacture of high-resolution active matrix OLED microdisplays for AR and VR headsets and other applications where the display is close to the eyes, has unveiled a prototype in WUXGA resolution (1920 x 1200 pixels). It uses Direct Patterning Display (dPd) technology to deliver a record high brightness of 10,000 cd / m22… According to the manufacturer, this is the world’s brightest full-color high-resolution OLED micro-display.
“This is a historic moment for eMagin and the industry, and this is our biggest achievement to date in developing our proprietary dPd technology,” said Andrew G. Sculley, CEO of eMagin. – By applying direct texture shaping to WUXGA displays, we have achieved a maximum brightness of over 10,000 cd / m22 and rich RGB colors. This is a 20x improvement over our standard XL white OLED micro-displays with a color filter and three to four times that of our new XLE micro-displays, and we consider it the brightest full-color high-resolution OLED micro-display in the world. We are working with a first tier customer on this development, including finding ways to produce it on an industrial scale.

“Brightness of full color image 10,000 cd / m22 – an important milestone on our path to creating full color displays with a brightness of over 28,000 cd / m22 by mid-2023, added Scully. – For comparison: a typical laptop monitor delivers 250 cd / m2 brightness2, and a high-quality smartphone – only 1000 cd / m22… In addition, our dPd displays contain more than 2,500 individually addressable pixels per inch (ppi), providing remarkable clarity and resolution compared to typical 330 PPI laptop screens and 600 PPI OLED smartphones. ”
