Encapsulation of OLED microdisplays

The challenge

OLED microdisplays require ultra-high quality thin-film encapsulation to enable long device lifetime. A typical encapsulation requirement is a water vapor transmission rate (WVTR) smaller than 1*10-6 g/(m2 day), which is challenging to achieve with conventional thin-film deposition methods due to low process temperature requirements.

The customer

Leading Asian OLED microdisplay manufacturer.
