Abstract: A touch sensor may include a substrate and may include electrode units, first demultiplexers, second demultiplexers, and driving pads all located on the substrate. The electrode units each may include a plurality of electrode groups, the electrode groups each including a plurality of touch electrodes. The first demultiplexers each may include a plurality of sub-demultiplexers and each may be electrically connected to a corresponding one of the electrode units. Each of the sub-demultiplexers of a first demultiplexer may be electrically connected to a corresponding one of the electrode groups of a corresponding electrode unit. The second demultiplexers may be connected between the first demultiplexers and the driving pads.

Abstract: A plasma display device including: a plasma display panel adapted to create images and including a front substrate, a rear substrate, a plurality of discharge cells defined between the front substrate and the rear substrate, and phosphors coated in the discharge cells; and a filter attached to a front surface of the front substrate and adapted to serve as an image display surface, wherein the filter and the phosphors are respectively colored with first and second colors that are different from each other.
