摘要： This disclosure provides an electroluminescent ("EL") display device having anode, cathode, insulator and organic EL layers. The anode and cathode layers sandwich the other two layers, and the insulator layer is patterned to selectively block flow of current through the EL layers, and thereby locally block generation of light. The patterned insulator layer allows a single panel to display multiple visual attributes, yet does not require electrode patterning. The patterned insulator can be fabricated using photoresist exposure and development procedures. The photoresist is laid on top of a commercially available substrate/electrode layered pair, and is developed to create an assembly that can be completed in a single vacuum deposition process. By etching a small region of the electrode from the commercially available layered pair, and by choosing a deposition frame that blocks deposition on a second, different small region, electrical terminals may be coupled to the panel with a reduced risk of an electrical short.

摘要： An organic electroluminescent device with a conducting polymer layer beneath the hole transport layer. A conducting polymer layer of doped polyaniline (PANI) is spin-cast onto an indium-tin oxide (ITO) anode coating on a glass substrate. Then a hole transport layer, for example TPD or another aromatic tertiary amine, is vapor-deposited onto the conducting polymer layer, followed by an electron transport layer and a cathode. Polyester may be blended into the PANI before spin-casting and then removed by a selective solvent after the spincasting, leaving a microporous layer of PANI on the anode. The conducting polymer layer may instead be made of a .pi.-conjugated oxidized polymer or of TPD dispersed in a polymer binder that is doped with an electron-withdrawing compound. An additional layer of copper-phthalocyanine, or of TPD in a polymer binder, may be disposed between the conducting polymer layer and the hole transport layer. The conducting polymer layer may serve as the anode, in which case the ITO is omitted.
