More recently, AMOLED and Super AMOLED displays have revolutionised the quality of smartphones. The latest breakthrough in optical electronics is the MicroOLED, which may well consign optical viewfinders in cameras to the same place that dinosaurs went.
Sony’s recently launched consumer-level XGA OLED EVF panel has been the talk of the town. But now, a new 0.61” MicroOLED panel available in the market packs a mind-boggling 5.4 million pixel density that is millions of pixels more than other OLED displays. This will be available in both monochrome (2560×2048 pixels) and 1280×1024 pixel 16 million colour SXGA formats.
What all this means for cameras is the ability to use truly electronic viewfinders, in turn giving the photographer better control over settings such as exposure or white balance and thereby resulting in superior image quality.
Even today, most photographers prefer to use optical viewfinders instead of electronic viewfinders because of various reasons such as lack of a dynamic range, battery life considerations and noticeable lag as digital images are processed. It is expected that the MicroOLED display can work on as little as 0.2 Watts of power.
Each high resolution image rendered on a MicroOLED display will allow a contrast ratio of 100000:1, which in turn means the ability to detect far more subtle tones in an image than is currently feasible.
MicroOLED are looking to market their panels toward applications that include displays used by surgeons during robot-assisted surgeries as well as professional grade video cameras.
