  • Patent number: 7714323
    Abstract: The present invention relates to an organic thin film transistor which includes an organic layer comprising an organic compound facilitating the ohmic contact between a semi-conducting layer and electrodes and serving as the semi-conducting layer. The organic thin film transistor according to the present invention has excellent electric contact between the semiconductor layer and the source electrode/drain electrode, and thus can be widely used as components for electric/electronic devices. As a result, as the materials for the source electrode or the drain electrode in the organic thin film transistor, materials which are less expensive and excellent in processibility though they have a low work function as the materials can be used.

  • Publication number: 20050094646
    Abstract: Disclosed are an IP (Internet Protocol) video terminal with a function for controlling video transmission/reception bandwidth and image quality and a control method thereof. While a call is in progress, the IP video terminal exchanges information with an opposite party and controls a transmission rate and quality of video from the opposite party. Moreover, while the call is in progress, the IP video terminal recognizes a network state and automatically controls video transmission quality according to a change of the network state. The IP video terminal can acquire more natural video by lowering a bandwidth value or/and an image quality value when quality of video from the opposite party is bad during the call.
