The OLED display market is now an established market with over $10 billion in annual revenue. OLEDs are mostly used in mobile devices - over 300 million AMOLED panels were produced in 2016, most of them used in smartphones. OLED panels are also used in TVs, tablets, smartwatches, laptops and VR headsets.

Back in 2001, eMagin started offering OLED microdisplays, which are tiny displays fabricated directly on the silicon control circuitry (on the CMOS). Since 2001, the OLED microdisplay market is growing slowly and these high-end microdisplays are mostly used in defense, medical and industrial applications due to their high cost. Many high-end digital cameras also use OLED microdisplays for their electronic viewfinder (EVF).
