Abstract

Abstract An organic electroluminescent device array encapsulating package including an organic electroluminescent device on a supporting substrate. A cover having a rim engaging the supporting substrate is spaced from and hermetically encloses the organic electroluminescent device. A dielectric liquid having benign chemical properties fills the space between the cover and the organic electroluminescent device, providing both an efficient medium for heat transmission and an effective barrier to oxygen and moisture.
