Abstract: The present invention has its purpose to provide a system and method for storing and transmitting a file using an Internet messenger, wherein a file of a messenger user is stored in a messenger function-performing file storage unit, which is separately connected to a messenger server, or the file storage unit is used as a relay point where a file is transferred between the messenger users, by utilizing P2P transfer technology of a conventional messenger system without additional log-on or installation of an additional program. To accomplish this object, the present invention provides a messenger system for storing and transferring a file using an Internet messenger which includes a messenger server and a plurality of messenger clients connected to the messenger server for exchanging a message or file with the messenger server. The messenger system of the present invention comprises a messenger function-performing file storage unit connected to the messenger server.

Abstract: There is a driving circuit disclosed for a field emission display which can reduce the power consumption and thus improve the reliability of high voltage elements by reducing the swing width of the driving voltage necessary for driving the gate, cathode and anode lines arranged to the field emission display.

Abstract: The present invention relates to a display, and more particularly, to circuit for driving a display of a low power consumption. For the purpose, the circuit includes a light emitting display of current driven type having a plurality of column electrode lines arranged in a column direction, a plurality of row electrode lines arranged perpendicular to the column electrode lines, and a matrix of pixels at crossing points of the column electrode lines and the row electrode lines, a power source part, a column driving circuit connected to the column electrode lines formed in the column direction for supplying/discharging a current to/from the column electrode lines, for driving the light emitting display of current driven type, and an electric transformer for, when the current supplied to the column electrode lines is discharged, recovering the current discharged from the column electrode lines and re-supplying a recovered current to the power source part.
