Abstract: The present invention describes the use of red, green and, if necessary, blue dopants dispersed in a universal host material as the active emitting layer in OLEDs. The universal host is transparent in the visible region, and may be emissive in the blue region when used as the blue emitting species or possesses carrier transport properties. By dispersing the dopants in the universal host, efficient energy transfer from host to guest and/or direct carrier recombination on the dopant takes place resulting in bright red, green or blue emission, depending on the dopant. The resulting spectra are characteristic of the guest molecules.

Abstract: In a method for manufacturing an organic EL device, a simple method for connecting a cathode and a cathode terminal is provided. First, anodes 2a to 2g are formed on a substrate 1, and a cathode terminal 4 is simultaneously formed. Next, a hole injection layer 5 and a light-emitting layer 6 are formed over the entire surface of the substrate by spin coating. Subsequently, at a position corresponding to the cathode terminal 4, a liquid containing powdered silver and a solvent is dripped from a container 7 of a dispenser. As this solvent, a solvent that dissolves the hole injection layer 5 and the light-emitting layer 6 is used. Accordingly, a throughhole is provided at the position corresponding to the cathode terminal 4, and this throughhole is filled with silver 8. Next, a cathode layer 9 is formed so as to cover the position at which the throughhole is provided.

Abstract: The present invention includes a low voltage, high current density, large area cathode for scrubbing of cathodoluminescent layers. The cathodoluminescent layers are formed on a transparent conductive layer fonned on a transparent insulating viewing screen to provide a faceplate. An electrical coupling is formed to the transparent conductive layer to provide a return path for electrons. The faceplate and the cathodoluminescent layers are placed on a conveyer in a vacuum. The cathodoluminescent layers are irradiated with an electron beam having a density of greater than one hundred microamperes/cm2. The electron beam may be provided by a cathode including an insulating base, a first post secured to the insulating base near a first edge of the insulating base and a second post including a spring-loaded tip secured to the insulating base near a second edge of the insulating base. The cathode also includes a first wire cathode having a first end coupled to the first post and a second end coupled to the spring-loaded tip of the second post. The first wire cathode is maintained in a tensioned state by the spring-loaded tip. The electron irradiation scrubs oxygen-bearing species from the cathodoluminescent layer. Significantly, this results in improved emitter life when the faceplate is incorporated in a field emission display. The display including the scrubbed faceplate has significantly enhanced performance and increased useful life compared to displays including faceplates that have not been scrubbed.

Abstract: A new organic EL display panel comprises transparent electrodes 2, an insulating layer 7, an organic luminous layer 4 and backside electrodes 5 successively laid on a transparent substrate 1. The insulating layer 7 is converted from a positive novolac, negative cyclized rubber or chemical amplified photoresist layer shaped to a grate pattern, by baking treatment to remove water and a solvent from the photoresist layer. Electric resistance of the insulating layer 7 is good enough to inhibit leakage of an electric current between the electrodes 2 and 5. The EL display panel reproduces a distinct image over a long term without growth of dark spots.
