Presentation Summary

3M is developing flexible encapsulation systems suitable for display and solid state lighting applications. Our transparent barrier films are made using an all vacuum web process on polyester (PET and PEN) substrates. Our initial product offerings have water vapor transport rates (WVTR) below 0.005 g/m2-day and are primarily intended for the e-paper and screen printed OLED markets. Next generation products will address the OLED handheld display and solid state lighting markets. These markets will need WVTR films in the 10-4 to 10-6 range.
We will present data showing that these low WVTRs can be achieved with 3M's technology. Pressure sensitive adhesives with good barrier properties (2-4 g/m2-day for 1 mil adhesives films) have been developed for use with our barrier films. 3M barrier films and adhesives are available in roll and sheet form. They provide a versatile encapsulation system for rigid and flexible devices that can incorporate value added features such as hard coat, anti reflection, UV cut, and light extraction functions.
