MicroOLED presents 5.4M dot bicolor and tricolor OLED microdisplays for enhanced digital image fusion at SPIE DSS 2012

MicroOLED’s quad pixel architecture brings new advances in high-resolution image processing and power efficiency in digital image fusion for defense and medical applications

A technical paper “ A 5.4M dot OLED Microdisplay for Digital Night Vision and Image Fusion” will be presented at SPIE DSS in


Baltimore, April 23 – 27: Grenoble, France, April 25, 2012—MicroOLED, a maker of highly power-efficient superior image quality microdisplays for near-to-eye applications, today announces that the company will demonstrate, at SPIE DSS in Baltimore, two prototype 5.4M dot 0.61 inch diagonal OLED microdisplays in bicolor and tricolor. The microdisplays are designed to enhance image resolution and lower the power consumption of digital image fusion used in defense, security and medical applications.

Digital image fusion, a process of combining video streams from multiple sensors into a single composite image, has important applications in thermal weapon sights, aviator night vision imaging systems and other emerging night sight and situational awareness equipment. Also, surgeons use image fusion systems to integrate and analyze preoperative images to plan and perform brain, spinal and other complex surgeries.


bicolor OLED microdisplay“MicroOLED’s bi- and tricolor OLED microdisplays broaden the performance attributes of our monochrome 5.4M pitch 0.61-inch diagonal microdisplay with a sub-pixel pitch of 4.7 microns by 4.7 microns operating at 0.2W, that we announced earlier this year. This megapixel pitch monochrome microdisplay was well received by professional camera and night vision system makers worldwide, so we are optimistic about the bicolor and tricolor 5.4M dot versions,” said Eric Marcellin-Dibon, CEO of MicroOLED. “In addition, with our quad pixel architecture, we have increasing flexibility to create new color filter arrangements. These will enable MicroOLED to develop new displays, which will further open up opportunities in the defense and medical markets. At SPIE DSS, we will demonstrate our 5.4M dot 0.61-inch bicolor and tricolor OLED microdisplays to the defense industry’s top researchers, scientists and market leaders and show what the next step will be in digital image fusion.”

Performance attributes MicroOLED’s bicolor OLED microdisplays can merge a 4.0M pixel image from a night vision sensor with a 1.3M pixel image from a thermal sensor, and its 0.61-inch diagonal is directly compatible with existing systems. The tricolor version enables MicroOLED to merge up to three high resolution images or two images and a graphical overlay, with the following resolutions: a 2.6M pixel B&W image with a 1.3M pixel red image and a 1.3M pixel cyan image. They will provide system integrators and end-users all of the strengths of optical and digital image fusion systems with none of the trade-offs.

MicroOLED conserves energy in digital image fusion systems by merging the video input signals from multiple sensors directly in the microdisplay rather than the processor. Also, as the subpixels in the quad-pixel architecture are square, the same shape as pixels used in night vision and thermal sensors, each subpixel can be used as a full pixel. This is unlike the stripe pixel architecture where one needs to use the full color triplet for each pixel.

Both optical and digital image fusion systems exist on the market. The strength of optical image fusion is that it can combine images originating from tube intensifiers with a high resolution (up to 2000 pixels) and thermal sensors (up to 1280x1024 pixels) with a fraction of energy, but at the expense of producing a lower quality composite image.

The strength of digital image fusion is that it can record, compress and transmit data, as well as improve the quality of the composite image by adjusting visual parameters. However, it draws more heavily on energy. Current models have a limited image resolution of ~ 1000 line maximum. For existing models to process images at a higher resolution would require not only increasing the power consumption, but possibly enlarging the display, as well as other system optics, which run counter to the military market trend in Swap (Size, Weight and Power) reductions.

At SPIE DSS 2012 MicroOLED will make available the viewing of the bi- and tricolor 5.4M dot OLED microdisplay prototypes by invitation at SPIE DSS in Baltimore, April 23 – 27. MicroOLED

CTO Gunther Haas will present a technical paper “A 5.4M dot OLED Microdisplay for Digital Night Vision and Image Fusion” during the “Head- and Helmet-Mounted Displays” session on Wednesday, April 25 at 2:00pm, at the Convention Center. SPIE Defense, Security and Sensing 2012 is one of the defense & security industry’s leading meetings for optronics equipment, and brings together top researchers, scientists and engineers from the military, industry and academia. Programs cover the latest enabling technologies and applications in infrared, sensors, image analysis, and other systems and devices.



Jan 2012: MicroOLED introduces highest pixel density OLED microdisplay


MicroOLED's new 5.4 mega pixels 0.61" diagonal microdisplay gives users SXGA resolution in full color at half the power consumption of competing products 


Grenoble, France, January 27, 2012 —MicroOLED, a maker of highly power-efficient superior image quality microdisplays for near-to-eye applications, today introduced a new 5.4 million pixel density 0.61 inch diagonal, low power consumption OLED (Organic Light-Emitting Display) microdisplay on silicon for applications demanding high picture quality, such as professional camera and camcorder equipment, night vision systems and head-mounted displays used in surgery. The ultra-compact 5.4 million-pixel microdisplay with a sub-pixel pitch of 4.7 micrometres by 4.7 micrometres is the highest pixel density OLED microdisplay available today. By doubling the pixel density of comparable products, MicroOLED has eliminated the gap between pixels. With no black matrix present, the resulting image resolution is of the highest quality. This makes the 5.4 million-pixel 0.61 inch diagonal microdisplay most suitable for defense, medical and professional camera applications that demand sharp images with very smooth transitional tones. 
 High contrast (maximum 100,000:1) and high uniformity (96 per cent) also play key roles in picture quality. Depending on how one drives the OLED microdisplay, it can perform using as low as 0.2W, half the power consumption of other products in its category.  MicroOLED achieves this low level power consumption even when the fully digital video input is embedded.

“We are really excited by the market potential of our new 5.4 million pixel density 0.61 inch diagonal OLED microdisplay that is superior in picture quality to any product in its category,” said Eric Marcellin-Dibon, CEO of MicroOLED. “This OLED microdisplay is already creating quite a stir among world leaders in imaging products who commend the high pixel density and the remarkable image quality. Moreover, the current trend in replacing optics with electronics components fits excellently with our ability to produce this exceptional picture quality in miniature format. We see many opportunities opening up in existing applications and new markets as a result.” 
MicroOLED will market the 5.4 million-pixel density 0.61 inch diagonal microdisplay to address needs in three areas: head-mounted displays used by surgeons, where high resolution and quality of colors and contrast are a must; professional camera and camcorders, where picture quality is key; and night vision applications, where heightened contrast and uniformity enable defense and security professionals to improve the performance of detection and identification equipment.

The 5.4 million-pixel density microdisplay comes in full color (16 million colors), SXGA or monochrome formats (2,560 by 2,048 pixels), both with digital video input. It meets the standard environmental operating requirements for military applications. The new product builds on MicroOLED’s exclusive OLED patent technology that is recognized for its ability to eliminate defects common in other microdisplays, such as color non-uniformity or fixed pattern noise.

  Jan 2008 : France Info interview with MICROOLED’s CEO.

Sitting on the train, a pair of glasses resting on your nose, watching your favorite movie. Miniature screens, about .16 by .31 inches, are typically used for viewfinders on digital cameras or camcorders. But MICROOLED, a French-based company, is now developing a new type of micro-screen and plans to market its first application, video-glasses, next year.

Éric Marcellin-Dibon, CEO and cofounder of MICROOLED.

E. M-D.: MICROOLED designs and manufactures highly energy-efficient, high-quality microscreens delivering high-resolution images. Primarily intended for video applications, these microscreens can be placed in a pair of video-glasses, which can be hooked up to portable multimedia players used to store music, movies, or games.

So if I put on a pair of these glasses, I’ll be able to use them to watch a movie?

E. M-D.: Right. These miniature screens will be built right into your glasses. Their optical system will provide you with the same image quality you enjoy when watching a high-res movie on your plasma screen at home. So these glasses will make it possible for you to display your TV shows, movies, or games… anywhere!

And it’s just like watching the screen right in your living room?

E. M-D.: Yes, completely. You get outstanding image quality and visual comfort. And since our screens are very tiny and don’t use up much power, these glasses are really lightweight and feel almost like regular glasses.

And I suppose this technology can be used for other applications.

E. M-D.: Yes, in medicine, to help the visually impaired. Or also in defense and security, or for professional cameras. So we’re currently working with our manufacturing partners to come up with and develop many other applications.

PARIS - The Laboratory for Electronic and Information Technologies of the French Atomic Energy Commission (CEA-Léti) recently set up an OLED screen development team featuring its internal talents in the areas of flat screens and above-IC technologies.
CEA-Léti states that the “keystone" of this operation is a cluster-type OLED deposition system, which has been incorporated into the 200-mm MEMS production line at Minatec and is associated with specific characterization equipment.
CEA-Léti explains that the results of this research will be enhanced by the efforts of the Grenoble-based young start-up MICROOLED, created in 2007.
The product of six years of R&D carried out at Thomson and CEA-Léti (Grenoble), MICROOLED plans to position itself as a supplier of very high-resolution, highly energy-efficient microdisplays for mobile video applications. The young start-up promotes its technology as being able to produce a resolution up to four times higher than that of the company’s competitors while consuming four times less energy.
These microdisplays are intended mainly for use in camcorders, digital cameras, and new mainstream (mobile video glasses) or professional (medicine, photography, defense) applications.

If everything goes according to plan, the next generation of glasses allowing users to watch films in high-def will incorporate embedded technology developed by MICROOLED, a start-up formed in Grenoble (France) in April 2007. But this very nearly didn’t happen. Indeed, in 2006, the French group Thomson decided to close its “display” division. This division supported the laboratory in Rennes (France) that, since 2000, had been developing the energy-efficient microscreen technology currently being manufactured by MICROOLED. The French Atomic Energy Commission (CEA) decided to transfer this technology to its Grenoble-based Laboratory for Electronics and Information Technology (LETI) and took over some of the production teams. And there was another stroke of luck. The US-based company HP provided logistical and financial support to Éric Marcellin-Dibon and Gunther Haas, both engineers at Thomson, so that they could form MICROOLED, which holds exclusive licenses to all patents associated with this technology. “We had already been asked by a number of manufacturers to sign development contracts. But we needed a structure,” explains Marcellin-Dibon.

The first video glasses are expected to hit the market in 2009. But this application will not be the only use for the microscreens. Assistance for the visually impaired, night vision, enhanced vision, high-def, 3D, there are a number of possibilities. This opens up significant growth opportunities for the company, which will handle the production of the screens. Within the next three years, MICROOLED plans to employ 30-40 people and achieve 10 million euros in sales.

Meet the screens that will revolutionize the world of video and perhaps even the world of vision…Based on OLED2 technology, these very high-resolution, highly energy-efficient microscreens can actually be used with integrated circuits. Video screens straight out of science fiction are thus becoming a reality…with the added bonus of a number of wireless applications. It will thus be possible to provide visually impaired readers with much larger characters from scanned pages, to view videos stored on a portable DVD player or mobile phone, to activate night vision during military operations, and to allow doctors to display patients’ X-rays on these transparent glasses, and thus help them make accurate diagnoses…all this relies on the device’s tiny size, its low voltage (3.3 volts), and the very high resolution of the restored images, much like the image quality delivered by 16/9 television screens3! This is a real advantage over the dark glasses used in virtual reality.
The basic technology developed by Thomson was transferred less than a year ago to CEA-Léti4, which then enhanced it. This technology is now being developed at MICROOLED, a company headed by Éric Marcellin-Dibon, Gunther Haas, and Christophe Prat. An initial prototype - manufactured using an integrated circuit - is expected to be available late this year.

2. Organic light-emitting diode. 3. Five times as many pixels as glasses used in virtual reality (i.e. 850 x 480 pixels per line for a 0.37” screen). 4. the Electronics and Information Technology Laboratory of the French Atomic Energy Commission (CEA)

MicroOLED is named winner of the 2007 French national competition for the creation of technologically innovative companies, organized by the French Department of Higher Education and Research.

New applications intended for mainstream (mobile video glasses) and professional (medicine, defense) use are currently being developed.

La lettre de l’économie, 2007



MICROOLED aims to become a supplier of high-resolution, highly energy-efficient microdisplays for mobile video applications. MICROOLED’S technology allows for the delivery of a resolution four times as high as that offered by the company’s competitors, while consuming four times less energy. These key advantages are due to the use of the OLED (Organic Light-Emitting Diode) technology developed by the team and protected by a large portfolio of patents. To date, this type of microscreen is mainly used in viewfinders on camcorders and digital cameras, but new applications intended for mainstream (mobile video glasses) and professional (medicine, defense) use are currently being developed. The potential of these markets appears to be highly attractive because MICROOLED’S technology is unique and addresses the strong, fast-growing demand for these applications.
