Abstract: A multi-layer thin film for encapsulation and the method thereof are provided. The multi-layer thin film for encapsulation includes a protective layer composed of aluminum oxide, a single or double barrier layer composed of silicon nitride (SiNx), and a mechanical protective layer composed of silicon dioxide (SiO2). The multi-layer thin film can be economically fabricated by using the existing equipment, and has a high level of light transmission over 85% while showing a low level of oxygen and moisture penetration. Additionally, due to superior adhesive strength between the thin films, and high resistance against impacts by heat or ion during a fabricating process, reliability of fabrication is enhanced, and it can thus efficiently used in encapsulating an organic light-emitting device (OLED), a flexible organic light emitting device (FOLED) in a display field, and the cells such as a thin film battery and a solar cell.

Abstract: An organic light-emitting display device, which may be configured to prevent moisture or oxygen from penetrating the organic light-emitting display device from the outside is disclosed. An organic light-emitting display device, which is easily applied to a large display device and/or may be easily mass produced is further disclosed. Additionally disclosed is a method of manufacturing an organic light-emitting display device. An organic light-emitting display device may include, for example, a thin-film transistor (TFT) including a gate electrode, an active layer insulated from the gate electrode, source and drain electrodes insulated from the gate electrode and contacting the active layer and an insulating layer disposed between the source and drain electrodes and the active layer; and an organic light-emitting diode electrically connected to the TFT.

Abstract: Disclosed are polyarylene ether sulfides and polyarylene ether sulfones for optical device and a method for preparing the same. Polyarylene ether sulfides containing fluorine and polyarylene ether sulfones containing fluorine are synthesized through polycondensation of pentafluorophenyl sulfide and pentafluorophenyl sulfone monomer with dihydroxy monomer. In addition, by attaching ethynyl phenol and phenylethynylphenol to terminals of the high molecular weight polymer, solvent resistance of the polymer is increased. Thus, the high molecular weight polymers prepared by very simplified process have low light loss, excellent resistance for heat, solvent and water, and so can be used to manufacture inactive optical waveguide devices.
