  • first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
  • Spatially relative terms such as “inner,” “outer,” “beneath”, “below”, “lower”, “above”, “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Abstract

La présente invention concerne une pile d'une pluralité d'éléments liés de manière adhésive de type à film mince accouplée de manière amovible à une structure électroluminescente. L'invention concerne également un procédé de nettoyage d'une surface électroluminescente. Le procédé consiste à retirer des feuilles polymères préalablement mises en place à partir d'une surface électroluminescente après des intervalles de temps préétablis. L'adhésif est conçu pour permettre le retrait d'une couche de feuille polymère découverte sans retirer la totalité de la pile d'éléments rectangulaires.
