MicroOLED’s 5.4M dot bicolour and tricolour microdisplays: the next step in image fusion?

Digital image fusion is a process of combining video streams from multiple sensors into a single composite image and has applications in night sight and situational awareness equipment. Surgeons also use image fusion systems to analyse preoperative images when planning complex surgeries. Eric Marcellin-Dibon, ceo of MicroOLED, said: "With our quad pixel architecture, we have increasing flexibility to create new colour filter arrangements. These will enable MicroOLED to develop new displays, which will further open up opportunities in the defence and medical markets." The bicolour microdisplay can merge a 4Mpixel image from a night vision sensor with a 1.3Mpixel image from a thermal sensor, while the 0.61in diagonal is compatible with existing systems. The tricolour version can merge up to three high resolution images or two images and a graphical overlay, with the following resolutions: a 2.6Mpixel black and white image with a 1.3Mpixel red image and a 1.3Mpixel cyan image. While digital image fusion requires more energy than optical systems, these devices conserve energy by merging the video input signals from multiple sensors directly in the microdisplay, rather than in the processor. The square sub pixels in the quad pixel architecture can also be used as full pixels. This could provide an advantage over stripe pixel architecture where the full colour triplet is needed for each pixel.
