  • Testing user terminal status
    Publication number: 20060159245
    Abstract: A network system and method of testing the terminal status so as to acquire the link status of the wired/wireless terminals associated to the VoIP-based network includes at least one user terminal which transmits a status message in response to a SIP-based Options message and a soft switch which transmits the Option message, determines whether or not the status message has been received, and recognizes whether the user terminal is in a Busy state or an Idle state based on a result of the determination. Since the terminal status can be accurately determined, it is possible to process calls, manage the terminal, and fairly charge the utilization costs to improve the stability and QoS of the network system.

  • Image display apparatus and drive method
    Publication number: 20060152451
    Abstract: Disclosed is an image display apparatus having, in every pixel, a light-emitting element such as an organic electro-luminescence (EL) element of which the brightness is controlled by a current. The image display apparatus includes transistors that form a current mirror in the pixel and using a pixel structure having two scan lines, so as to select pixels of at least two rows simultaneously, distribute the current applied to the data line to the pixel for recording display information and the adjacent pixel, and record the display information on the pixel of no more than one row among the selected pixels. This drastically increases the current for driving the data line and decreases the size of the transistors that form the current mirror in the pixel.

  • Method for manufacturing high voltage transistor
    Publication number: 20060148185
    Abstract: A method for manufacturing a high voltage transistor is disclosed. The method includes sequentially forming gate oxide films, polysilicon layers, and silicon nitride films on a semiconductor substrate; patterning the silicon nitride films, the polysilicon layers, and the gate oxide films using photolithographic and isotropic etching processes to form nitride film shades and polysilicon gate electrodes; implanting impurity ions into the substrate using the nitride film shades as protective barriers; performing an annealing process to form source and drain diffusion regions of a double diffusion structure; and removing the nitride film shades. Therefore, since the silicon nitride films are used as the protective barriers during impurity ion implantation, the source and drain diffusion regions can be formed in a double diffusion drain junction structure without forming a space oxide film.

  • Display and a driving method thereof
    Patent number: 7057589
    Abstract: In a display, capacitors are charged with first precharge voltages at the time of applying selection signals to previous scan lines. A data driver divides a plurality of data lines into a plurality of groups each of which consists of at least one data line and applies corresponding data voltages to the data lines of respective groups sequentially. The display further includes a precharge means, and such precharge means applies second precharge voltages to data lines of at least one group before selection signals for selecting scan line are applied to the scan line connected to the pixel circuits and stops application of the second precharge voltages before corresponding data voltages are applied to the respective groups. In this way, it is possible to solve the problem of poor images due to charge redistribution of the capacitors caused by previous data voltages stored in parasitic capacitors.

  • Method and apparatus for determining GPRS mobile terminal connection mode
    Publication number: 20060116134
    Abstract: A method for determining a GPRS mobile terminal connection mode is disclosed. Whenever a GPRS data service is requested, a mobile terminal counts the number of attempted of GPRS connections and the number of successful GPRS connections to calculate a GPRS connection rate, compares the calculated connection rate with a predetermined connection rate. If the calculated connection rate is greater than the predetermined connection rate, the mobile terminal changes the GPRS connection mode to a ‘when needed mode’, whereas if the calculated connection rate is not greater than the predetermined connection rate, the mobile terminal changes the GPRS connection mode to an ‘always on mode’. Accordingly, by changing the connection mode in a GPRS network, network resources can be better utilized and the connection rates can be increased.

  • Organic electroluminescence display and method of operating the same
    Publication number: 20060114196
    Abstract: An organic electroluminescence display and a method of operating the organic electroluminescence display are disclosed. A pixel array unit, including a plurality of pixels, is divided into at least two pixel groups adjacent to each other. The first pixel group is selected by a first scan driving unit and the second pixel group is selected by a second scan driving unit. Scanning lines for selecting the first pixel group extend into the first pixel group and scanning lines for selecting the second pixel group extend into the second pixel group. Accordingly, each scanning line is reduced in length and thus impedance of the scanning line is decreased. The reduction of impedance prevents delay or distortion of scan signals.
