eMagin Unveils 'World's Smallest Pixel Pitch Microdisplay'

By Rahul Prabhakar, TMCnet Contributing Editor

eMagin Corporation, a pioneer in OLED microdisplay technology and personal display systems, bundles high-resolution OLED microdisplays with magnifying optics. The company offers virtual images akin to large-screen computer and television displays in portable, low-power, lightweight personal displays.

The company recently showcased its new innovations in power-efficient microdisplays and its prototype SVGA-3DS microdisplay at the Society for Information Display Conference and Exhibition held at the Long Beach Convention Center, California, from May 22-24, 2007. eMagin also demonstrated various applications for personal display systems based on its OLED microdisplays and modules.

An elated Susan Jones, executive vice president and chief marketing officer, eMagin Corporation, said in a statement, “We demonstrated OLED-XL technology a year ago and implemented it across our product line ahead of schedule.”

“This year it’s the backbone of our product line and the basis for even more advanced microdisplay products,” she added.

The developers have handed over the first prototype units of the high-density OLED-on-silicon SVGA-3DS microdisplay, providing both analog as well as digital signal processing in a compact display (0.44-inch). This solution offering provides greater efficiency, cost-effectiveness, increased functionality, and easy integration for innumerable virtual imaging systems. Additionally, it removes the need to have extra circuitry and components, allowing a smaller display module design with no increase in power consumption.

The company has made major improvements in the new microdisplay, such as, increased pixel uniformity, on-chip temperature sensor and compensation, better color gamut, and compatibility with both analog RGB and digital video signals.

The 800 x 600-pixel array includes triads of vertical sub-pixels stacked closely to form each 11.1 x 11.1-micrometer color pixel. The versatile timing controls houses a number of video formats. On-board circuitry enables consistency in color and brightness over a wide range of operating temperatures.

The OLED-XL displays are based on eMagin’s original active matrix SVGA-3D and SVGA+ integrated circuits, showcasing 4X improvements in efficiency and significantly higher luminance at levels power consumption as compared to eMagin’s original products.

eMagin’s scientists and engineers also presented two papers at the conference, titled: “A Low-Power AMOLED Microdisplay with Ultra-High Pixel Density and Extended Operating Temperature Range” and “High-Performance Top-Emitting OLED Devices.”

The company also featured a transparent binocular display, as part of its award-winning Z800 3DVisor(TM), microdisplays and modules in products from Nivisys and Total Fire Group, and its flagship WFO5 prism optic made to deliver an apparent large-screen virtual image.

In the recent times, eMagin has been one of the strongest participants at the Society for Information Display since the company’s inception. For more information about eMagin and its clientele, visit www.emagin.com.
