    摘要： Methods for creating a protective seal (24) suitable for protecting polymer-based electronic devices, including light emitting diodes and polymer emissive displays, are disclosed together with the protected devices. The protective seal (24) includes one or more thin films of silicon nitride or other inorganic dielectric applied at a low temperature. One or more nonreactive metal layers may be present in the protective layer as well. Other embodiments are disclosed which include a protective cover over the protective layers. These protective layers provide encapsulation with sufficient protection from the atmosphere to enable shelf life and stress life polymer electronic devices that are adequate for commercial application.

    摘要翻译： 与受保护的装置一起公开了用于形成适于保护基于聚合物的电子装置（包括发光二极管和聚合物发射显示器）的保护性密封件的方法。 保护性密封件包括在低温下施加的一种或多种氮化硅（SiN）或其它无机电介质的薄膜。 一个或多个非反应性金属层也可以存在于保护层中。 公开了包括保护层上的保护盖的其它实施例。 这些保护层提供了具有足够保护的封装，从而能够满足商业应用的聚合物电子器件的保质期和应力寿命。

    摘要： This invention pertains generally to the field of light-emitting diodes, LEDs. More particularly, this invention relates to polymer LEDs which offer high brightness, high efficiency, and extended operating life, and which comprise: a transparent hole-injecting anode layer (11); an emissive layer comprising an electroluminescent polymer (12); and an electron-injecting cathode layer (13); the cathode layer comprises an ultra-thin layer of alkaline earth metal, such as calcium, strontium, and barium, having a thickness of about 100 Angstroms or less, typically from about 15 to about 100 Angstroms.
