When people think of displays with a resolution of 2560×2048 they might imagine something measuring 30 inches or more, God forbid it be some underwhelming massive screen with an abysmal pixel density such as todays HD TV’s.
MicroOLED has created a 4.5 megapixel display with just such the specifications and it fits right in front of your eye. Its new 0.61 inch display is powered by efficient OLED technology that allows it to create incredibly small pixels to achieve such high pixel density in less than an inch of area. This will allow them to create high resolution color (1280×1024) and black and white (2560×2048) viewfinders and head mounted displays.
The display is being built to meet military requirements and is being developed for medical professionals, for viewfinders in professional camera equipment and for night vision applications.
