23.2: An Efficient Stacked OLED with Double-Sided Light Emission
An efficient double-sided emitting OLED employing a stacked geometry has been fabricated. It uses a reflective composite silver electrode as the middle reflective layer. It can be used in a passive matrix (PM) driving scheme with independent control of both displays. Superior electroluminescent (EL) performance of the OLED on both (“bottom” and “top”) sides can be easily achieved without interf...
متن کامل29.3: Very Bright and Efficient Top-Emitting OLED with Ultra-Thin Yb as Effective Electron Injector
Very bright and efficient top-emitting organic light-emitting diodes (TOLEDs) using an ultra-thin ytterbium (Yb) layer capped with a semitransparent Ag layer as the effective electron-injection cathode were demonstrated. TOLED with Yb/Ag cathode exhibited lower operation voltage and higher power efficiency, as compared to the one with commonly used Ca/Ag cathode. With bis(2-phenylpyridine)iridi...
متن کاملSpectrum study of top - emitting organic light - emitting devices with micro - cavity structure ∗
Blue and white top-emitting organic light-emitting devices OLEDs with cavity effect have been fabricated. TBADN:3%DSAPh and Alq3:DCJTB/TBADN:TBPe/Alq3:C545 were used as emitting materials of microcavity OLEDs. On a patterned glass substrate, silver was deposited as reflective anode, and copper phthalocyanine (CuPc) layer as HIL and 4’-bis[N-(1-Naphthyl)N-phenyl-amino]biphenyl (NPB) layer as HTL...
متن کاملOmnidirectional emission from top-emitting organic light-emitting devices with microstructured cavity.
We demonstrate optimized viewing-angle characteristics from top-emitting organic light-emitting devices by integrating a periodic microstructure into the cavity. A holographic lithography technique combined with filling process of the groove by spin coating of a polymer film has been employed to enable its periodically and gradually changed cavity length and suppress the viewing-angle dependenc...
متن کامل7.3: Reliability Enhancement of AM-OLED with a-Si:H TFT and Top-Anode OLED Employing a New Pixel Circuit
Abstract: This paper reports a new pixel circuit suitable for enhancing the reliability of AM-OLED with the a-Si:H TFT backplane and top-anode OLED structure. The propose pixel circuit is composed of 5 a-Si:H TFTs for switching and driving device, and it does not require any complicated drive ICs. The compensation of OLED current against threshold voltage shift of the drive TFT has been verifie...
