Abstract: Disclosed is a method and device for searching for a telephone number in a mobile terminal having a direction key that consists of a left arrow, a right arrow, an up arrow and a down arrow. The method includes displaying one or more consecutive digits input by a user in a standby mode of the mobile terminal; and when a quick search key and any arrow of the direction key are pressed simultaneously, searching for a telephone number including the displayed digits in a position corresponding to the pressed arrow.

Abstract: An apparatus and method for recognizing a code from a code image that is expressed physically or electronically and extracting data represented in the code image is provided. The method includes the steps of receiving a raw image in which a code image is contained, detecting a background image included in the raw image, extracting a code image region in which a background image is excluded, recognizing the shape and type of the code image and the color or shade represented in each of cells, converting the color or shade recognized from each of the cells into a corresponding character, number, or symbol and generating code data. The code image in which predetermined data are represented as colors or shades are received, and original colors or shades can be precisely discriminated regardless of an environment in which the code image is recognized.

Abstract: There is disclosed an energy recovering circuit with boosting voltage-up and an energy efficient method using the same that are capable of boosting the voltage factor of an energy recovered from the panel to rapidly re-appl it to the panel, to thereby reduce the charging time of a panel capacitor and improve its energy recovery efficiency. An energy recovering circuit according to the present invention includes a voltage boosting circuit for boosting a voltage factor of an energy recovered from a panel and supplying the boosted energy to the panel. An energy efficient method according to the present invention includes steps of recovering an energy from a panel to a closed loop; and a controlling the closed loop in order to supplying the energy with its voltage factor boosted to the panel.

Abstract: An optimal light-emission pattern generation method for a plasma display panel according to an embodiment of the present invention includes steps of determining a plurality of light-emission patterns with respect to an arbitrary gray level; calculating a contour noise degree between a contour noise free gray level being set in advance and the light-emission patterns given to each gray level in plurality; and selecting a light-emission pattern whose contour noise degree is minimal as a light-emission pattern with respect to an arbitrary gray level.

Abstract: A plasma display panel that is adapted to be driven with a low-level voltage signal. A source electrode is supplied with a voltage and a trigger electrodes is opposed to the source electrode. A first discharge is generated between each source electrode and each trigger electrode to apply a voltage at source electrode to a panel electrode.

Abstract: This invention relates to a driving method and apparatus for a plasma display panel, and more particularly to a method of generating an optimal light-emission pattern for a plasma display panel in order to select a light-emission pattern where a moving picture pseudo contour noise is minimized.

Abstract: Circuit and method for driving a plasma display panel, the method including the steps of (1) applying first scan pulses to a first driving block, which is any one of the driving blocks, in every given driving cycle starting from a first scan electrode line to (n)th scan electrode line in succession, and (2) applying second scan pulses each having a given application time difference from the application time of the first scan pulse to a second driving block adjacent to the first driving block starting from (m)th scan line to a first scan line in a reverse sequence to the first scan pulses, whereby preventing an occurrence of flicker because interfaces between driving blocks are continuous with respect to and providing a PDP having a resolution better than an HDTV because intervals of scan pulse application to adjacent lines are short.

Abstract: Provided is a method of driving a plasma display panel, which is a sub-field driving method for the plasma display panel with scan and addressing drive signals, including the steps of: a) dividing scan lines of a field into at least two areas, and scanning the areas; b) displaying a sub-field by applying different address pulses to the respective areas during the scanning; and c) repeating the preceding steps to drive the sub-field, thereby displaying the field.

Abstract: A disk drive constructed according to an exemplary embodiment of the present invention includes a disk having a plurality of tracks formed concentrically along a first surface of the disk for storing data. The tracks are divided into first and second data storage regions positioned between an innermost circumferential region and an outermost circumferential region of the disk. First and second heads write and read data to and from the first surface of the disk. The first head is positioned to access the first data storage region while the second head is positioned to access the second data storage region, and the first head being positioned to access the second data storage region while the second head is positioned to access the first data storage region. First and second arm assemblies are respectively connected to the first and second heads. The first arm assembly extends the first head over a first radius of the disk, and the second arm assembly extends the second head over a second radius of the disk.
