Other Applications
Microdisplays are also used in thermal imaging as well as in night vison cameras, where an image is usually captured within a for the human eye invisible range of frequency (infrared), then by a microcontroller colored with a specific set of colors and finally displayed in front of the users eyes using a microdisplay.
Mostly all of these cameras are battery powered mobile devices. Thus, also for these applications OLED microdisplays due to their incredible low energie needs are predestinated to be used over all the other microdisplay technologies.
