The present invention relates to a plasma display apparatus. The plasma display apparatus according to a first aspect of the present invention includes a plurality of discharge cells, and a Plasma Display Panel (PDP) in which a unit frame is driven with it being divided into a plurality of subfields, wherein when noise is included in the unit frame, the number of subfields constituting the unit frame, a color temperature and the number of sustain pulses are controlled by adjusting an output gain value of an output data. The plasma display apparatus constructed above according to the present invention checks random noise introduced to an input video data, and controls the number of subfields used in a noise screen by adjusting a gain. Accordingly, there are advantages in that a phenomenon in which heat is generated by a signal input to a data drive IC can be prevented, and damage to the panel, which is incurred by the generation of heat, can be prevented. Furthermore, since a reduced number of subfields can be driven, portions corresponding to extra subfields can be utilized for other purposes. Accordingly, there is an advantage in that driving margin can be enhanced. |
