Abstract:
An apparatus for driving a three-electrode alternating current (AC) surface discharge plasma display panel (PDP) includes a scanning driver, an address driver, a common driver and a controller. The scanning driver, in which a scanning circuit is combined with a discharge sustaining circuit with respect to each of the scan electrode lines, applies scanning signals to scan electrode lines in response to scan data in a predetermined scanning order during an address period for forming wall charges at pixels to be selected and also applies discharge sustaining signals to scan electrode lines in response to discharge sustain data during a sustain-discharge period for generating light at the selected pixels.
Abstract:
In a plasma display device, a secondary coil of a transformer is connected across a panel capacitor formed by a scan electrode and a sustain electrode performing a sustain discharge. The plasma display device uses resonance between a secondary coil of a transformer and a panel capacitor to apply a sustain discharge pulse to a scan electrode and a sustain electrode in a sustain period.

Abstract:
Methods and systems for providing company call service in wireless and wired integrated network are provided. For example, a call between an employee's wireless device and a client's device can be connected while indicating the employee's wired telephone number as a caller's telephone number. When an employee is receiving a call, one example is to call an employee's wired device first, and if there is no response, employee's wireless device may be called subsequently. In another example, employee's wired and wireless device may be called simultaneously.
Abstract:
There is provided an organic electroluminescence device employing a multi-layered pixel electrode and a method of fabricating the same. The organic electroluminescence device comprises a substrate, a first pixel electrode located in a predetermined area on the substrate, and a second pixel electrode located on the first pixel electrode and entirely covering the first pixel electrode. Thus, the film breakdown due to the galvanic phenomenon is precluded.
Abstract:
A method for displaying gray levels in a PDP by generating gray data corresponding to externally input image signals and displaying the gray data on the PDP is disclosed. The method comprises generating reference signals based on the image signals, determining a spread filter value according to states of the reference signals, applying the spread filter value to the gray data and generating final gray data, and displaying the final gray data on the PDP. The present invention reduces contour noise generated between moving pictures' adjacent grays.
Abstract:
Reset, address, and sustain operations of a plasma display device are performed by applying a driving waveform to a scan electrode while biasing a sustain electrode at a ground voltage. Then a driving board for driving the sustain electrode may be eliminated. In addition, a discharge between the sustain electrode and the scan electrode as well as between an address electrode and the scan electrode may be ensured in an address period by accumulating positive wall charges on the sustain electrode at an end of a falling period of a reset period.

A chemical vapor deposition unit is invented for forming a uniform thin film over the entire surface of a substrat by the vapor-deposition. The chemical vapor deposition unit comprises a reaction chamber isolated from the outside and kept under vacuum, a susceptor, on which at least one substrate is placed, installed in the reaction chamber such that it can rotate, and an injector, including independently formed first and second gas passages, and first and second gas injecting pipes that communicate with the respective gas passages and respective outlets, for injecting respective first and second gases onto the susceptor, the injector injecting the different gases independently. The injector further comprises a gas injecting part for communicating with the second gas passage so that only the second gas, which is a non-reactive carrier gas, is injected in a central region of the susceptor.
