A method of controlling an operation of a mobile terminal having a display screen, and which includes displaying a plurality of avatar images on the display screen, wherein at least a first avatar image represents a first party registered in a phone book of the mobile phone; detecting, via a controller of the mobile terminal, an occurrence of the communication event associated with the first avatar image, the first avatar image having a first shape indicating a first action; and changing the first shape of the first avatar image into a second shape indicating a second action of the first avatar image to inform a user of the mobile terminal about the detected occurrence of the communication event.

Mobile terminal and method of controlling operation of the mobile terminal

A mobile terminal and a method of controlling the operation of the mobile terminal are provided. The method includes displaying an idle screen; if a communication event occurs, displaying an avatar image corresponding to a party of the communication event on the idle screen, the communication event including making or receiving a call and sending or receiving a call; and modifying the avatar image according to the amount of occurrence of the communication event. Therefore, it is possible for a user to easily recognize the occurrence of a communication event and the amount of occurrence of the communication event from an avatar image displayed on an idle screen.

There is provided a plasma display device. The plasma display device includes a plasma display panel (PDP) and drivers for supplying driving signals to the PDP. The driver includes a capacitor, a first switch turned on in order to supply a voltage of a first end of both ends of the capacitor to the PDP, a second switch turned on in order to supply a voltage of a second end of both ends of the capacitor to the PDP, a first voltage supplier connected to the first end of the capacitor to supply one of a sustain voltage and a reference voltage to the first end, and a second voltage supplier connected to the second end of the capacitor to supply the reference voltage to the second end. A voltage difference between the both ends of the capacitor is sustained as the sustain voltage. In the plasma display device, since the conventional large capacity of pass switch and the negative polar scan voltage source&#x2014;Yy are replaced by cheap capacitors with the driving signals for driving the PDP applied in the same way, it is possible to reduce the manufacturing cost of the plasma display device.
