  • Patent number: 8863177
    Abstract: A system for inserting advertisement data into broadcast data and method thereof are provided. The system and method can output advertisement data to a certain portion of a lower end of a screen image of the new channel for a certain time when a current channel is changed to a different broadcast channel according to a viewer's intention while the viewer is viewing a broadcast program, thus minimizing viewer's reluctance to the advertisement output, reducing the burden of an advertiser, and guaranteeing a visual continuity of a broadcast program desired to be searched. Using the present invention, when channels are switched for searching for broadcast programs or when power is turned on or off, advertisement data can be output to the same screen while outputting a pertinent broadcast program, thereby exposing the advertisement data without interrupting the broadcast program.

  • Patent number: 8445898
    Abstract: The present invention relates to an organic/inorganic hybrid thin film passivation layer comprising an organic polymer passivation layer prepared by a UV/ozone curing process and an inorganic thin film passivation layer for blocking moisture and oxygen transmission of an organic electronic device fabricated on a substrate and improving gas barrier property of a plastic substrate; and a fabrication method thereof. Since the organic/inorganic hybrid thin film passivation layer of the present invention converts the surface polarity of an organic polymer passivation layer into hydrophilic by using the UV/ozone curing process, it can improve the adhesion strength between the passivation layer interfaces, increase the light transmission rate due to surface planarization of the organic polymer passivation layer, and enhance gas barrier property by effectively blocking moisture and oxygen transmission.
