Provided is an operating method of an image forming apparatus, the operating method including broadcasting a plurality of packets comprising identification information of the image forming apparatus; receiving a connection request comprising the identification information of the image forming apparatus from a mobile terminal which received some packets from among the plurality of broadcasted packets; and connecting to the mobile terminal, based on the connection request, wherein the connection request is transmitted from the mobile terminal when received signal strengths of the some packets received by the mobile terminal are equal to or greater than a first threshold value. In this regard, the first threshold value may indicate a received signal strength greater than a minimum received signal strength at which communication with the mobile terminal is available.

A method and apparatus is provided for managing private data, such as a phone book, in a multifunction peripheral (MFP) used by multiple users. The method involves receiving user information and performing user authentication, and reading data stored in a user area allocated to the authenticated user in a storage unit divided into a number of user areas. Accordingly, when private data is managed in an MFP used by multiple users, by dividing a storage unit in which data is stored into a number of user areas, allocating the divided user areas to users, and allowing a user to access only a user area allocated to the user through an authentication process, the private data can be fully prevented from being accessed by other users, and it will be unlikely for a user to be confused because of other user data.

Method and apparatus for managing private data in multifunction peripheral

A Plasma Display Panel (PDP) capable of reducing an address discharge voltage between address electrodes and Y electrodes, suppressing an address discharge delay, and improving brightness includes: a first substrate, a second substrate spaced apart from the first substrate and facing the first substrate, barrier ribs arranged between the first and second substrates and defining discharge cells where a discharge occurs, discharge electrode pairs including X electrodes and Y electrodes extending across the discharge cells, floating electrodes arranged closer to the Y electrodes than to the X electrodes, address electrodes extending across the discharge cells and intersecting the discharge electrode pairs within the discharge cells, and phosphor layers arranged within the discharge cells. Portions of the address electrodes facing the Y electrodes are wider than portions of the address electrodes facing the X electrodes, or distances between the Y electrodes and the portions of the address electrodes facing the Y electrodes are shorter than distances between the X electrodes and the portions of the address electrodes facing the X electrodes.

Plasma display panel (PDP)

A PDP (plasma display panel) includes: a first substrate; a second substrate arranged opposite to the first substrate; first barrier ribs arranged between the first substrate and the second substrate and formed of a dielectric material; second barrier ribs arranged between the first barrier ribs and the second substrate and formed of a dielectric material, the second barrier ribs partitioning discharge cells together with the first barrier ribs; first discharge electrodes arranged within the first barrier ribs to surround the discharge cells; second discharge electrodes arranged within the second barrier ribs to surround the discharge cells; phosphor layers arranged within the discharge cells; and a discharge gas injected in the discharge cells, in which sides of the first and second barrier ribs form concave portions.

Plasma display panel provided with discharge electrodes arranged within upper and lower barrier ribs assemblies

A plasma display panel includes a first substrate and a second substrate arranged to oppose one another with a predetermined gap therebetween. Address electrodes are arranged on the first substrate, and barrier ribs are arranged between the first and second substrates to independently define discharge cells. Phosphor layers are arranged in the discharge cells. Sustain electrodes are arranged on the second substrate along a direction perpendicular to the address electrodes. Each of the discharge cells includes first and second sides arranged along the direction of the address electrodes, and third and fourth sides arranged along the direction of the sustain electrodes. The first and second sides are convexly arranged in a direction away from each other, and the third and fourth sides are concavely arranged.
