Display panel with variable information, e.g. for teaching aid, uses magnetic plates placed in required positions on document with metal backing sheet

摘要

The display panel comprises a metal sheet (1) sandwiched between a backing layer (2) and a document (3), and a number of movable components (E) with information on one surface, stuck to magnetic strips (5) which allow them to be positioned as required on the document. The backing layer is designed to increase the rigidity of the metal sheet, and both it and the document are stuck to it with double-sided adhesive layers (8), assembled under pressure. The movable elements are made up in the same way. The document and movable elements can have their surfaces protected by plastic covering.
