Patent ID: 7768476

Claim:
A plasma display apparatus comprising: a plasma display panel having first and second address electrode groups that correspond to first and second screen regions respectively, wherein the first screen region and the second screen region are scanned simultaneously; a first plurality of data drive ICs each including channels connected to the first address electrode group, the first plurality of data drive ICs including at least a first data drive IC and a second data drive IC; a second plurality of data drive ICs each including channels connected to the second address electrode group, the second plurality of data drive ICs including at least a third data drive IC and a fourth data drive IC; a first data alignment unit to supply data to the first plurality of data drive ICs; and a second data alignment unit to supply data to the second plurality of data drive ICs, wherein an nth channel of the first data drive IC from a first side of the first screen region is a dummy channel, an nth channel of the second data drive IC from a second side of the first screen region is a dummy channel, an nth channel of the third data drive IC from a first side of the second screen region is a dummy channel, and an nth channel of the fourth data drive IC from a second side of the second screen region is a dummy channel, and the first side of the first screen region and the first side of the second screen region correspond to a same side of the plasma display panel.
