Abstract:
1. A method for encapsulating a light emitting polymer (LEP) device having an air-stable electrode (cathode), the method comprising the steps of: obtaining the LEP device from an ambient environment; heating the LEP device to a temperature that substantially removes surface moisture and residual solvents from at least one surface of the LEP device; outgassing the LEP device; and laminating the at least one surface of the LEP device with encapsulating material, the encapsulating material providing the at least one surface of the LEP device with a barrier from an operational environment, wherein: the step of laminating comprises the steps of: the step of applying includes applying a bottom pressure sensitive adhesive sheet to a bottom side of the LEP device; the step of rolling includes rolling a bottom encapsulating material onto the bottom side of the LEP device; and the step of sealing includes:
