An organic electroluminescent display and a method of manufacturing the same are provided. More particularly, a method and system are disclosed for retaining a plurality of small particulates, preferably in the shape of beads, which contact sludge or other despots on the membrane filters to remove unwanted debris that would otherwise form on the cleaning filters. With the center, playable digital or audio media data can be advantageously transported, organized, played or recorded through or on a variety of products or devices. Determining the interference signal emitter may also include comparing the measured interference signal to known interference signals.
