  • top emitting 230 dots in active Matrix Polymer light emitting diode displays on flexible metal foil substrates
    Applied Physics Letters, 2007
    Co-Authors: Tako Chuang, Matias Troccoli, Abbas Jamshidiroudbari, Miltiadis K Hatalis, Ivan Biaggio, Apostolos T Voutsas
    Abstract:

    A top-emitting 230dots∕in. monochrome active-Matrix Polymer light-emitting diode (PLED) display having the VGA format and fabricated on a flexible steel foil utilizing the polycrystalline silicon thin-film transistor (TFT) technology is reported. The pixel circuitry architecture consists of the conventional two TFT circuitries made of two p-channel metal-oxide-semiconductor (PMOS) transistors and one storage capacitor. The average field-effect hole mobility and threshold voltage of the PMOS polysilicon TFTs fabricated on the metal foil are 37(±4)cm2∕Vs and −1.9(±0.6)V, respectively. The light turn-on voltage of the PLED is 4.0V.

  • The effect of flexible chains on the orientation dynamics of small molecules dispersed in Polymer films during stretching
    Polymer Journal, 2015
    Co-Authors: Shogo Nobukawa, Yoshihiko Aoki, Yoshiharu Fukui, Ayumi Kiyama, Hiroshi Yoshimura, Yutaka Tachikawa, Masayuki Yamaguchi
    Abstract:

    The effect of flexible chains on the orientation dynamics of small additive molecules in cellulose acetate propionate (CAP) films is investigated during stretching using birefringence and polarized Fourier-transform infrared (FT-IR) spectra measurements. The orientation birefringence is enhanced by additives such as ethylene 2,6-naphthalate (C_2Np) and hexamethylene 2,6-naphthalate (C_6Np) oligomers, suggesting that the additives orient parallel to the CAP chain as a result of an intermolecular orientation correlation referred to as the nematic interaction (NI). At a high drawing temperature, the orientation of C_2Np is stronger than that of C_6Np, indicating that the flexible alkyl chain has reduced the intermolecular NI with CAP. By contrast, C_6Np orients along the stretching direction at low temperatures. Polarized FT-IR spectra show that the orientation of the rigid portions of C_6Np is delayed relative to those of the flexible groups and the Matrix CAP chain. Consequently, the contribution of C_6Np to birefringence and its wavelength dependence become stronger as the draw ratios increase. Orientation dynamics of small additive molecules in Polymeric films during hot-stretching was investigated by using birefringence analysis and polarized Fourier-transfer infrared (FT-IR) spectroscopy. Birefringence data indicated parallel orientation of the small molecules to main chain of the Matrix Polymer. Furthermore, polarized FT-IR spectra demonstrated that the ratio of orientation functions of rigid and flexible portions in hexa-methylene naphthalate oligomer showed temperature dependence. The result suggests that the small molecules exhibit two-step orientation in the Matrix Polymer during stretching.
