Abstract
Methods for encapsulating OLED structures disposed on a substrate using a soft/polymer mask technique are provided. The soft/polymer mask technique can efficiently provide a simple and low cost OLED encapsulation method, as compared to convention hard mask patterning techniques. The soft/polymer mask technique can utilize a single polymer mask to complete the entire encapsulation process with low cost and without alignment issues present when using conventional metal masks. Rather than utilizing a soft/polymer mask, the encapsulation layers may be blanked deposited and then laser ablated such that no masks are utilized during the encapsulation process.
