eMagin’s OLED-XL™ Microdisplays

Already the most power-efficient system solution for virtual imaging devices, eMagin’s OLED microdisplays based on the company’s new OLED-XL™ Technology feature significant improvements in efficiency luminance, operational lifetime, and reliability.

The new OLED-XL™ devices typically feature significantly longer (>2x) half life or exhibit at least twice the nominal luminance under the same drive condition. The new technology also improves on eMagin OLED microdisplays’ industry-leading power efficiency, depending on the specific OLED-XL™ product and operating parameters.

For the OLED-XL™ microdisplays, eMagin scientists developed a more efficient OLED structure while maintaining pixel-level efficiency. The results are brighter microdisplays that require no additional power consumption.

To enable current customers to upgrade more easily in order to take advantage of new structure’s significantly improved power efficiency, eMagin’s first OLED-XL™ microdisplays use the same electronic IC design and register settings as its field-tested SVGA+ Standard and SVGA 3D products.

The OLED Advantage

Lower Power Consumption

Lower power consumption means fewer batteries. Users can stay in the field for longer periods of time and increase their range and mobility while reducing fatigue from added weight.

  • Uses 80% less power than LCDs
  • Reduces Weight from Extra Batteries
  • Increases Range and Mobilty

Wider Operating Temperature

LCD’s are a liquid-based display technology and cannot operate at extreme temperatures. For temperatures below 0°C , LCD’s require additional heating elements. At high temperatures, some sort of cooling is required. Each “solution” adds more weight, more bulk, and requires more power.

eMagin’s OLED microdisplays operate from -46°C to +70°C without the need for heaters or coolers.

  • Solid-State Hardware
  • No Heating or Cooling Required
  • Operating Temperature of -46ºC – +70ºC

Wider Viewing Angle

OLED microdisplays have a nominal viewing angle of 160°; approximately 265% larger than LCD displays.

  • 160º Viewing Angle
  • 265% Larger than LCDs

Greater Contrast Ratio

LCD displays with their inherent back-light requirement have a nominal contrast ratio (pure black to pure white) of 60:1. With no need for a back light and the ability to turn a pixel absolutely off, OLED microdisplays have a nominal contrast ratio of 10,000:1.

  • No Backlight Required
  • True Black
  • 10,000:1 Contrast Ratio

Faster Response Time

OLED pixels can refresh (change color and/or intensity) in less than one micro-second. The nominal refresh rate for LCD’s is 10 – 15 milliseconds; 1,000 to 1,500 times slower. The net result is that OLED microdisplays show a much smoother moving image, which reduces eye-fatigue and eliminates headaches.

  • <1µ Second Response Time
  • 1,000 to 1,500 Times Faster than LCD
  • Instant On
  • Smoother Motion
  • Reduces Eye Fatiigue and Headaches

The Advantage of OLED on Silicon

OLED Component IllustrationOrganic LED technology uses an organic compound to produce light when power is applied. Because OLEDs produce their own light, there is no need for additional back-lighting as with LCD systems. True black can be achieved by turning off the current to a given element, whereas only dark grey is possible in back-lit systems. As a result, OLED displays naturally offer a vast improvement in sharpness and contrast.

eMagin’s OLED microdisplays are Solid State and rely on fewer components, which minimizes power consumption and dissipation, and the likelihood of failure. Fabricating the OLED microdisplay onto the circuitry that controls and processes the video signal, results in a minimal package with increased reliability, ruggedness, and efficiency.

Each OLED can produce nearly the entire spectrum of visible light. Microscopic red, green, and blue filters are overlaid and can be selectively combined to produce any color. There are million of elements per display which combine to produce over 16.7 million colors.

Data for each OLED element is buffered right at the pixel location so the duration between changes for the element is as fast as possible. The result is a very fast response time and no image jitter. The image is crisp and sharp, and user eye-fatigue is greatly reduced.

Onboard 3D image processing can also be performed on the same silicon chip when a frame sequential signal is sent to two displays. This is true 3D continuous display (not alternating left / right shuttering). Eye fatigue is greatly reduced.

Fiber Optic Faceplate

For 3rd-Party Optical Systems which require the display image to be on the topmost surface plane

With the addition of a Fiber Optic Faceplate, eMagin microdisplays can be coupled to third-party optical systems which require the display image to be on the topmost surface plane.

The .5mm and .7mm (SXGA) Fiber Optic Faceplate replaces the standard glass cover, ensuring the same compact form factor. The Fiber Optic Faceplate does not affect color, contrast or image resolution.

  • Brings the display image to the topmost surface
  • For integration with 3rd-party optical systems
  • Replaces the Existing .5mm (SVGA+) or .7mm (SXGA) glass cover
  • No adverse effect on color, contrast or resolution
