  • Publication number: 20120303182
    Abstract: The present invention relates to a system and method for managing a vehicle through a wireless communications relay of a vehicle remote controller, which save additional communication costs by using an inexpensive and universal communication module such as a Bluetooth or Wi-Fi module instead of an existing mobile communication network, and are greatly economically beneficial and have high market adaptability by applying the existing communication module as-is to an existing mobile communication terminal and to an existing vehicle control means, in the management of the vehicle through a vehicle control terminal such as a mobile communication terminal capable of executing various applications.

  • Patent number: 7928975
    Abstract: In a plasma display and a driving method thereof, a misfiring prevention period is provided between a reset period and an address period in response to a temperature of the plasma display being higher than predetermined temperature or a weight value of a previous subfield being higher than a predetermined weight value. In the misfiring prevention period, a first voltage higher than a voltage supplied to a sustain electrode is supplied during a first period, and a voltage at a scan electrode is gradually decreased from a second voltage to a third voltage during a second period subsequent to the first period.

  • Publication number: 20080252564
    Abstract: Provided is a method of driving a plasma display panel (PDP) that comprises X electrodes, Y electrodes, and address electrodes, wherein a frame, which is a display cycle, comprises a plurality of subfields for time-divisional gray scale display. Each of the subfields includes a reset period, an address period, and a sustain period. The reset period is one of a main reset period during which both a rising pulse and a falling pulse are applied to the Y electrodes and an auxiliary reset period during which one of the rising pulse and the falling pulse is applied to the Y electrodes, and the main reset period comprises a first pulse time during which a pulse rising to a level of a first voltage and then falling to a level of a second voltage is applied to the Y electrodes and a second pulse time during which a pulse rising to a level of a third voltage and then falling to a level of a fourth voltage is applied to the Y electrodes.
