Title: Highly transparent non-metallic cathodes
IPC: H01L33/40
Filed: 1998-10-08
Abstract: A novel class of low reflectivity, high transparency, non-metallic cathodes useful for a wide range of electrically active, transparent organic devices are disclosed. As a representative embodiment, the highly transparent non- metallic cathode of an OLED employs a thin film of copper phthalocyanine (CuPc) capped with a film of low-power, radio-frequency sputtered indium-tin-oxide (ITO). The CuPc prevents damage to the underlying organic layers during the ITO sputtering process. Due to the low reflectivity of the non-metallic cathode, a non-antireflection-coated, non-metallic-cathode-containing TOLED is disclosed that is 85 % transmissive in the visible, emitting nearly identical amounts of light in the forward and back-scattered directions. The performance of the non- metallic-cathode-containing TOLED is found to be comparable to that of TOLEDs employing a more reflective and absorptive cathode consisting of a semi-transparent thin film of Mg:Ag capped with ITO. The present invention is further directed toward novel OLEDs in which the highly transparent non-metallic cathodes may be used in OLEDs comprised of a charge carrier layer containing a compound having molecules that have at least one electron transporting moiety and at least one hole transporting moiety, OLEDs comprised of an emissive layer containing an azlactone- related dopant, OLEDs comprised of an emissive layer containing a phosphorescent dopant compound, or OLEDs comprised of a hole transporting layer containing a glassy organic hole transporting material comprised of a compound having a symmetric molecular structure.

Abstract: PURPOSE: A plasma display panel is provided to improve luminescence and emission efficiency and accomplish low power consumption with improved structure of MgO protection layer. CONSTITUTION: A plasma display panel comprises a pair of sustain electrodes, a dielectric layer, and a MgO protection layer. The MgO protection layer is partially removed between 1/4-2/4 portion of the width of the sustain electrode from the inner boundary of the pair of the sustain electrodes to directly expose the dielectric layer to discharge space. Because cathode electrode discharge spreading significantly depends on secondary electron emission due to collision of ion and the MgO protection layer, the removal of the MgO protection layer reduces cathode electrode discharge spreading. In spite of the removal of the MgO protection layer, anode electrode discharge spreading does not changed. The cathode electrode discharge spreading is stopped at the removed portion of the MgO protection layer, and then discharge path in the removed portion is lengthened.
