  • Patent number: 8792609
    Abstract: A shift register is discussed in which a pull-up switching device is turned off positively in a period in which no scan pulse is forwarded for securing drive stability and prevents a picture quality from becoming poor. The shift register in one embodiment includes stages having any one of first and second start pulses, and any one of first to fourth clock pulses to forward a scan pulse in succession, wherein the first and second start pulses are in gate high voltage states for two horizontal periods, with the second start pulse forwarded with a delay of one horizontal period than the first start pulse. The first to fourth clock pulses are in gate high voltages for two horizontal periods, with one horizontal period delay to one another.

  • Patent number: 8725812
    Abstract: Disclosed is a method and system for providing memo in electronic mail. Memo data is further added to general mail data. Electronic mail sender sends electronic mail including memo data. The memo data may be inserted in the mime header or may be inserted in the form of attachment file, or may be inserted in the mail body. Besides that mail sender inserts memo data, mail receiver can also insert memo data to received mail for mail management. Users can check identify mail more conveniently through memo related to mail. A memo icon is provided in mail read page, and memo is displayed to users when mouse event on the memo icon occurs.

  • Patent number: 8312083
    Abstract: Disclose is a method and system for sharing search result using messenger. A messenger client generates search request information and receives web page data corresponding to the search request information. A search server receives the search request information from the messenger client and performs a search for one or more keywords included in the search request information to transmit search result page data to the messenger client. When the search result page is transmitted from the search server, a layer coupled to a conversation window is formed to display the search result page and allow users to share the information on web page corresponding to the search results when requested.

  • Patent number: 8055717
    Abstract: Disclosed is a method and system for storing mail permanently without restriction of storage space of mail box. When user requests to store certain mail permanently, mail server transforms the requested mail data into permanent mail data with predetermined format. The transformed mail data is transmitted to an external server, the external server is a various kind of server that provides personal information storage space. The external server stores received permanent mail data on corresponding user area. If user requests to read permanent mail, the mail server requests the requested permanent mail data to the external server, and the external server transmits the requested permanent mail data to the mail server, by which users can read mails indicated as permanent mail regardless mail capacity of mail box.
