A plasma display and a driving method thereof. At least one of the plurality of probes is exposed to a charged particle beam of the charged particle beam device, and a second electrical signal is compared to the first electrical signal to determine a characteristic associated with the at least one of the plurality of probes. The gate electrode is on the gate insulation layer pattern, the gate electrode including a lower portion having a first width, a central portion having a second width smaller than the first width and an upper portion having a third width. The invention is more particularly useful in the building sector, in particular for flooring, wall facing or ceiling finish, with panels, laths or wainscots made of different materials, such as wood, skin materials and synthetic materials.
