Abstract
Auto-adhesive display film comprising at least one electrically charged, dielectric layer (2). A screen layer (3), which is adapted to form a barrier to the electric field, is fixed to one surface of the dielectric layer (2). This display support does not attract dust particles and is specifically adapted to be printed sheet by sheet.
Claims18
An auto-adhesive display film adapted to automatically adhere to smooth surfaces comprising at least one first dielectric layer (2), said layer comprising, on the one hand, a first surface, and, on the other hand, a second surface which is electrically charged, the display film being characterised in that a first screen layer (3), adapted to form a barrier to the electric field, is fixed to at least, said first surface of the first dielectric layer (2).
Display film according to any of the preceding claims, wherein the material constituting the first layer (3) is a metal.
Display film according to any of the preceding claims, wherein the material constituting the first layer (3) comprises at least one transparent and conductive metallic oxide.
Display film according to any of the preceding claims, wherein the first dielectric layer (2) and the first screen layer (3) are transparent.
Display film according to any of the preceding claims wherein the first screen layer (3) is permanently fixed to the first dielectric layer (2).
Display film according to any of the preceding claims, wherein a removable cover foil (7) is fixed to the second surface of said first dielectric layer (2), this cover foil comprising at least one second screen layer (5).
Display film according to any of the preceding claims, wherein the first screen layer (3) is continuous.
