Disclosed herein is a plasma display panel in which afterimage is improved. The plasma display panel according to the present invention includes a panel unit having an upper plate and a lower plate, a frame that supports circuitry, and a conductive material formed between the panel unit and the frame. As such, a conductive material is formed on a bottom surface of a lower plate of a panel. Thus, charges introduced into the lower plate are properly controlled to improve the waveform stability of the panel. Also, a charge characteristic is improved to implement a stable operation. Accordingly, an afterimage time can be reduced. Further, a sheet of a low hardness and light weight is used. It is thus possible to absorb shock and noise of a PDP, accomplish light weight of the PDP and reduce the materials of the sheet.

Disclosed herein is a combined varistor and LC filter device in which both a varistor function of protecting circuits by absorbing surge voltage and an electromagnetic interference filter function of improving radiation characteristics are implemented in a single chip, thus having reduced mounting area. The combined device includes a body which acts as an insulator at voltages below a predetermined level, and the resistance of which decreases rapidly at voltages above a predetermined level. Inductance patterns constituting an LC resonant circuit, capacitance patterns and ground patterns are implemented in the body in a multilayer structure. The combined device operates as an LC filter at a low voltage and operates as a varistor at a high voltage.

The invention provides a low divide ratio programmable frequency divider of a fractional-N type applied to a digital MOPLL tuner and a method thereof. In the invention, a divide ratio assigner assigns divide data as a main divide ratio and a pulse swallow value according to a first or a second dividing operation mode in response to a mode selection signal. A prescaler operates on the first or second divide operation mode in response to the mode selection signal. Also, a main counter divides a frequency from the prescaler by the main divide ratio. Further, a pulse swallow counter counts a clock of the main counter while outputting a pulse swallow signal to the prescaler. The pulse swallow signal has a swallow level if a counting value corresponds to the pulse swallow value, and a non-swallow level if the counting value does not correspond to the pulse swallow value.

A method of transmitting one text message to a plurality of receivers is disclosed. The method includes inputting numbers of the receivers and a text message to be transmitted, determining a type of a transmission speed of the inputted text message, and transmitting the inputted text message of the determined type to numbers of the respective receivers. If the text message transmission succeeds, the method further includes confirming whether any further receivers of the text message exist and, if so, inputting new numbers of the further receivers and re-transmitting the corresponding text message to the new numbers of the further receivers. In inputting the phone numbers of the receivers, the sender can transmit the text message more rapidly and conveniently using the phonebook function and one-touch dial function.
