    Abstract: In one embodiment of an OLED device, a hole injection/transport layer is added to the device structure in order to increase the number of holes injected into the emissive layer and reduce the number of electrons injected into the added hole injection/transport layer. In a first configuration of the added hole injection/transport layer, the added hole injection/transport layer is comprised of a non-doped hole transporting material that has an IP range between the highest IP value of the adjacent layer on the anode-end and the lowest IP value of the adjacent layer on the “emissive layer”-end. Optionally, in addition, nearly all electron affinities of the added hole injection/transport layer are less than the lowest electron affinity of the adjacent layer on the “emissive layer”-end. In a second configuration of the added hole injection/transport layer, this layer is formed by doping the hole transport material. The dopant is able to abstract electrons from the hole transporting material. By doping the hole transport material, the IP range of the hole transporting material is broadened. In addition or alternatively, the doping produces more HOMO energy states thus allowing more holes to occupy these intermediate states at any one time.

    Abstract: Methods for protecting circuit device materials, optoelectronic devices, and caps using a reflowable getter are described. The methods, devices and caps provide advantages because they enable modification of the shape and activity of the getter after sealing of the device. Some embodiments of the invention provide a solid composition comprising a reactive material and a phase changing material. The combination of the reactive material and phase changing material is placed in the cavity of an electronic device. After sealing the device by conventional means (epoxy seal for example), the device is subjected to thermal or electromagnetic energy so that the phase changing material becomes liquid, and consequently: exposes the reactive material to the atmosphere of the cavity, distributes the getter more equally within the cavity, and provides enhanced protection of sensitive parts of the device by flowing onto and covering these parts, with a thin layer of material.
