The present invention relates to a plasma display panel and, more particularly, to an apparatus and a method of driving a plasma display panel. According to the present invention, an apparatus for driving a plasma display panel includes a line buffer unit synchronizing data inputted from outside with a horizontal synchronization signal to store per horizontal line, at least one comparison unit comparing loads included in horizontal lines stored in the line buffer unit, and a data converting unit correcting the data to be supplied to the horizontal lines using a load difference resulting from a comparison by the at least one comparison unit. According to the present invention, a method of driving a plasma display panel includes the steps of detecting loads included in externally inputted data to be supplied to at least two adjacent horizontal lines and correcting the data to be supplied to each of the at least two adjacent horizontal lines according to a load difference between the at least two adjacent horizontal lines. Accordingly, the loads included in the previous and current lines are computed to correct the data to be supplied to the lines according to the load difference between the respective lines, respectively. Therefore, the present invention enables to correct the brightness difference between the horizontal lines and to prevent power dispersion of the heavily-loaded horizontal line.

A liquid crystal display and a driving method for preventing a phenomenon causing a non-uniform charge characteristic between liquid crystal cells are disclosed. The liquid crystal display includes a picture display part having a plurality of gate lines and a plurality of data lines and having liquid crystal cells sharing a data line. A gate driver sequentially supplies a scanning pulse to the gate lines. A source output enable signal generator alternately generates a first source output enable signal having a first horizontal period and a second source output enable signal delayed from the first source output enable signal by a time longer than a half of the first horizontal period and shorter than the first horizontal period. A data driver supplies data voltages to the data lines in response to the first and second source output enable signals.

The present invention relates to an apparatus for driving a plasma display panel and method thereof, and more particularly, to an apparatus for driving a plasma display panel and method thereof in which a width of a scan pulse varies depending on whether data exist or not, thus improving the image quality. According to an embodiment of the present invention, the apparatus includes a plasma display panel for displaying video data, a data detection part for detecting whether video data received from an input line exists or not, an APL calculation part for generating an APL signal corresponding to a stage of the number of a sustain pulse supplied to the plasma display panel depending on whether the video data from the data detection part exists or not, and a timing controller for varying a width of a scan pulse supplied to the plasma display panel depending on whether the video data from the data detection part exists or not and also varying the number of the sustain pulse supplied to the plasma display panel in response to the APL signal. According to the present invention, it is possible to improve brightness by increasing the number of a sustain pulse of a sustain period in a region where normal video data is supplied.

Systems and methods are presented for achieving various operational modes of packetized wireless network communication, specifically IEEE 802.11 Wireless LAN (WLAN), 802.16 Wireless MAN and WiMAX communication. By providing for various operational modes an increase in the overall security of the wireless network can be realized. The invention is based on the application of a single cryptosystem and on the application of multiple cryptosystems. The invention addresses to aspects of WLAN security, namely, the protection of the information transmitted through the radio link of WLANs, and the invisibility of the network equipment, such as Access Points (APs), to unauthorized adapters.
