 ### 8. encapsulation
-Since OLED devices are really sensible to moisture and oxygen, encapsulation process is really important to maintain a long lifetime. The are multiple encapsulation technologies :
+OLED devices are highly sensitive to moisture and oxygen. They require a water vapour transmission rate (WVTR) of less than 10<sup>–6</sup> g/m²/day. For this reason, the encapsulation process is crucial for maintaining a long lifetime. There are multiple encapsulation technologies:

 The use of these technologies depends on multiple parameters of the screen.
