Provided is a channel resource assignment method for fair channel resource reservation in a mesh WPAN, in which the amount of channel resources is fairly reserved when devices share the channel resources. The channel resource assignment method in a mesh Wireless Personal Area Network (WPAN) includes the steps of: (a) transmitting beacons of all devices and adding an amount of channel resource to be reserved to the beacons so as to assign the channel resource for fair channel resource reservation between corresponding devices and adjacent devices when a mesh network is configured; (b) accumulating the amount of the channel resources reserved by all the adjacent devices except the corresponding device; and (c) determining the amount of the channel resources to be reserved.

Disclosed in an anthracene derivative, an organic electronic device using the anthracene derivative, and an electronic apparatus including the organic electronic device. The anthracene derivative is capable of being used as a hole injecting material, a hole transporting material, an electron injecting material, an electron transporting material, and a light emitting material in an organic electronic device including an organic light emitting device. In particular, the anthracene derivative is capable of being used alone as a light emitting material and a host or a dopant in a host/dopant system. The organic electronic device is excellent in views of efficiency, driving voltage, life time, and stability.

A flat panel display integrated with a touch screen panel. The connecting patterns, which connect adjacent first sensing cells and adjacent second sensing cells are formed on the same level of the lower surface of the upper substrate of the flat panel display of the same material as metal patterns formed around the edge of the touch screen panel, and by arranging the connecting patterns not to cross each other. The flat panel display panel can also be integrated with a touch screen having improved visibility by forming the touch screen panel on the upper substrate of the flat panel display such that connecting patterns are formed in the regions between the pixels.
