摘要： A method for fabricating an electroluminescent display and the substrate and apparatus used therein. The display is preferably constructed on a pre-constructed substrate that includes a flexible base layer having a conducting surface on one side thereof. The base layer is impermeable to oxygen and water. The substrate includes a plurality of wells defined by a barrier layer, each well having an electrode layer connected electrically with the conducting surface. A removable protective layer covering the wells protects the electrode layer from attack by oxygen and water prior to being utilized to make the display. In one embodiment, each of the wells also contains an electron transfer layer in contact with the electrode layer. The electron transfer layer includes a material that improves the efficiency of the injection of electrons from the electrode layer into the electroluminescent layer of the display. This display is fabricated by moving a first dispenser relative to the substrate so as to quantitatively deposit a first electroluminescent material on the substrate, different amounts of the first electroluminescent material being deposited at different locations on the substrate in response to signals defining an illumination pattern to be generated by the display. A conducting material is deposited on the first electroluminescent material. In color displays, a second electroluminescent material is also deposited, the second electroluminescent material emitting light at a different wavelength than the first electroluminescent material. A non-luminescent material, which is preferably an electrical insulator, can be deposited in wells at locations on the display that are not to emit light prior to depositing the conductive material.

摘要： An organic light emitting device having a process compatible current self-limiting (CSL) structure applied in the vicinity of an electrode of the device prevents the occurrence of high current flow in the vicinity of a short within the device. Should a short occur, the CSL structure becomes resistive, or non-conducting in the vicinity of the short, thus preventing the occurrence of “runaway” current in the vicinity of the short. By limiting the current flow between conductors in the device, the non-emissive areas of the device can be minimized, thus improving the overall reliability of the device.

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.

摘要： A color organic electroluminescent device includes color filters, light emitting layers and substrate integrated into a single assembly, with the light emitting layers lying between the substrate and the color filters. Unlike color electroluminescent devices where an image must be viewed through a transparent substrate, or where color filters are deposited upon another device and later combined with the assembly, the present disclosure calls for a transparent protective layer of silicon nitride or a similar material to be deposited over the light emitting layers to protect the light emitting layers from oxygen and moisture, and to serve as a platform for color filters. In order to achieve sufficient density in the protective layer and avoid defects, a cold plasma deposition or similar process is used for deposition of the protective layer. By viewing light through this protective layer instead of a substrate, nearly any substrate can be used.

摘要： An OLED display device and a method of fabricating the device utilize a patterned layer of conductive pads formed over a substrate to fabricate a cathode layer without the need to subsequently pattern the cathode layer to create individually addressable cathodes. The design of the OLED display device is such that the cathode layer is positioned below the anode layer. The OLED display device may be configured to emit light through the substrate or through the top layer, i.e., the anode layer. In a first embodiment, the conductive pads have sharp edges that effectively pattern the cathode layer when it is formed over the pads. In a second embodiment, the conductive pads do not include sharp edges. In this embodiment, the cathode layer is made of a composite material, which includes cathode components and non-conducting components. The composite material allows the resulting cathode layer to have the desired characteristics to effectively inject electrons vertically into the EL region of the device, while limiting lateral conduction between the conductive pads.
