  • Publication number: 20090205005
    Abstract: Disclosed is a method of providing additional content in a digital broadcast reception apparatus, the method including receiving a locator of additional content from a broadcast server while a user watches a broadcast program, receiving an instruction to insert the additional content from the broadcast server, receiving and reproducing the additional content from a content providing server designated by the locator, and switching back to the broadcast program. Thus, it is not necessary to allocate a separate channel and/or to switch channels for providing additional content.

  • Patent number: 7573070
    Abstract: An organic light emitting display and method of fabricating the same are provided. The organic light emitting display and the method of fabricating the same in accordance with the present invention is capable of preventing an organic layer pattern from being cut due to a step between a first electrode and an inorganic pixel defining layer by forming an inorganic pixel defining layer having an opening for exposing at least a portion of the first electrode to a small thickness using a deposition method. In addition, since the first electrode and the organic layer pattern are closely adhered during a transfer process to enable the transfer process using a laser beam having low energy, thereby improving transfer efficiency, improving luminous efficiency of the OLED, and increasing lifetime of the OLED.

  • Publication number: 20060046357
    Abstract: The present invention relates to a method for fabricating thin film transistor, more particularly, to a method for fabricating thin film transistor which not only manufactures a polycrystalline silicon layer having large grain size and containing a trace of residual metal catalyst by heat treating thereby crystallizing the metal catalyst layer after forming an amorphous silicon layer on a substrate, forming a capping layer formed of nitride film having 1.78 to 1.90 of the refraction index when crystallizing the amorphous silicon layer and forming a metal catalyst layer on the capping layer, but also controls characteristics of the polycrystalline silicon layer by controlling the refraction index of the capping layer. The present invention provides a method for fabricating thin film transistor comprising the steps of preparing an insulation substrate; forming an amorphous silicon layer on the substrate; forming a capping layer having 1.78 to 1.
