Abstract: An organic electroluminescent display device and fabrication method thereof is provided. The device includes a first substrate having at least one thin film transistor; an electroluminescent unit formed on the first substrate and electrically connect to the thin film transistor; a first protective layer formed on the electroluminescent unit; a second protective layer formed on the first protective layer; and a third protective layer formed on the second protective layer and in contact with the first protective layer. The device further comprises a second substrate sealed to the first substrate to form the electroluminescent unit between the first substrate and second substrate. In the device, the first protective layer comprising inorganic material, the second protective layer comprising organic material and the third protective layer comprising inorganic material are formed on the electroluminescent unit to reduce oxidation of electrodes by preventing infiltration of moisture.

Abstract: A flashlight bulb of the type having a sealed envelope from which two pins extend in parallel relationship can be removably mounted in a PR-type base by the use of an insert that fits within the PR-type base and that includes, in addition to the holes for the pins, balls that are urged laterally against the pins by compression springs within the insert. The balls establish electrical contact with the pins and are connected by conductors to the terminals of the PR-type base.
