摘要:
A plasma display panel (PDP) that has a T-shaped electronic structure or an electrode structure with adjacent parts of the scan electrode and the sustain electrode being broad, and parts coupled to the bus electrodes being narrow in a like manner to the T-shaped electrode structure is provided. The PDP has various discharge modes according to magnitudes of sustain discharge voltages. A frame is divided into a plurality of subfields with respective weights and is driven in the PDP. The subfields with low weights use low sustain discharge voltages to perform a discharge with a small quantity of emitting light, and the subfields with high weights use high sustain discharge voltages to perform a discharge with a big quantity of emitting light, thereby increasing representation performance of low gray scales.
