  • Publication number: 20140242354
    Abstract: Provided are an encapsulation film formed by stacking at least one bilayer including a thin layer composed of graphene oxide or reduced graphene oxide and an organic polymer layer and a method for forming the same. Since the encapsulation film is formed by stacking at least one bilayer including a thin layer composed of graphene oxide or reduced graphene oxide, the encapsulation film can represent an excellent blocking property with respect to oxygen and moisture. Parallel diffusion of the oxygen and the moisture in the encapsulation film may be significantly limited by maximizing a thickness of the organic polymer layer formed between the thin layers.

  • Publication number: 20140077692
    Abstract: A flat panel display device and a manufacturing method thereof. In the flat panel display device, a thin film encapsulation structure covering a display unit on a substrate includes an alternating layers stack in which organic layers and inorganic layers are alternately stacked; and an AlOx layer on the alternating layers stack as an outermost thin film layer of the thin film encapsulation structure. According to the above structure, because the protective film is adhered onto the AlOx layer of the thin film encapsulation structure, which has a relatively weak adhesive force, the adhering and releasing processes may be performed smoothly, and thus, the thin film encapsulation structure may be prevented from being damaged in the adhering and releasing processes.

  • Patent number: 8421063
    Abstract: The general inventive concept relates to an organic light emitting display that has the same area where the upper and lower electrodes of a capacitor are overlapped for adjacent pixels, for respective pixels that constitute the organic light emitting display but implements the sizes of the upper and lower electrodes to be different. This thereby prevents the display quality of horizontal line shaped spot generated due to the effects of a critical dimension (CD) distribution from being degraded.
