Highly transparent non-metallic cathode

(57) Abstract: extensive electrically active organic transparent devices useful new class of low reflectivity high transparency metallic cathode is disclosed. Typical embodiments, highly transparent non-metallic cathodes of the OLED employs a thin film of low-power radio-frequency sputtered indium tin oxide copper phthalocyanine covered with a film of (ITO) (CuPc). CuPc during ITO sputtering process, prevent damage to the organic layer below. The low reflective metallic cathode, emits light of nearly the same amount of forward and backward scattering directions, discloses a TOLED with a non-metallic cathodes non antireflective coating having 85% transmission in the visible range. Performance TOLED with a non-metallic cathode was covered with ITO Mg: has been found to be comparable to the performance of the TOLED using cathodes of the absorbent in more reflective consisting semitransparent thin film of Ag. The present invention further comprises at least one electron transporting moiety and at least one novel OLED used in the OLED with a charge carrier layer that includes a compound having molecules having a hole transporting moiety, luminescent layer comprising azlactone-related dopant OLED, OLED having an emission layer comprising a phosphorescent dopant compound, to an OLED having a hole transporting layer containing a glassy organic hole transporting material comprising a compound having a symmetric molecular structure.
