  • Patent number: 9087480
    Abstract: In a scan lines driver that is used for driving scan lines of an organic light emitting diodes (OLED) display, a large voltage drop can develop between the gate or source of one of its transistors and the corresponding drain during a scan signal outputting period. This large voltage drop can excessively stress the one transistor. However, in accordance with the present disclosure, a voltage drop dissipating, second transistor is provided in series with the first transistor for absorbing part of the large voltage drop and thus reducing the stress that is applied to the first transistor.

  • Publication number: 20100174622
    Abstract: A sound source search system is capable of searching for a sound source using map information. If particular area information among the map information is selected, a sound source search client requests sound source tag information and sound source information associated with the selected particular area information. A sound source search server delivers the sound source tag information and the sound source information to the sound source search client in response to the request. The sound source search client displays one or more sound source tags corresponding to the particular area information on a screen based on the sound source tag information and sound source information received from the sound source search server.
