Offering better comfort to users of point-and-shoot digital cameras, and new designs for video glasses with the highest resolution ever, Microoled and the CEA-Leti have targeted these and many other potential applications with the announcement of the most efficient silicon-based OLED microdisplay in the world.

MicroOLED designs and develops high-performance microdisplays for near-to-eye applications. The company’s core offering consists of highly integrated microdisplays for use in video glasses for mobile HDTV, viewfinders for cameras, and professional applications.

Microoled and CEA-Leti announce the OLED microdisplay with the finest pixel pitch (more than 1.7 million sub-pixels, 2 to 4 times more than the other emissive technologies) and the lowest power consumption reported to date (4 times more efficient). This very compact 0.38” WVGA microdisplay from Microoled is based on the exclusive OLED technology licensed from Thomson and CEA, and integrates the latest know-how and key technologies developed by the teams of Microoled and CEA-Leti. This display is perfectly suited for camcorder and digital still camera eye-pieces as well as for video or interactive eyeglasses.

An efficient collaboration
“Marrying the capabilities of CMOS and the flexibility of OLED offers a unique route to microdisplays with unequalled resolution and brightness. We foresee a tremendous potential of applications for theses devices. The high resolution and the low power consumption makes it perfect for a large set of nomadic products”, said Laurent Malier CEO of CEA-Leti.

Excellent picture quality is an essential requirement that cannot be compromised. MicroOLED has successfully met the challenge of achieving a very small pixel with good color and grey level rendition, along with maximum brightness.

Our solution addresses these key technical constraints:

Due to their low optical transmission (only a few percents) LCD microdisplays are limited in resolution and can't simultaneously achieve high resolution, compactness and low power consumption. Shrinking the pixel size in order to increase resolution is not a solution – transparency will be further reduced, resulting in low luminosity or high power consumption, as well as increased visibility of pixellisation. Consequently, it is not possible to produce a higher resolution LCD that is limited to a reasonably small size.

LCOS microdisplays can achieve high resolution but at the cost of a complex illumination system and high power consumption.
