Problems solved by technology

[0010] However, such laminated protective windows are not completely transparent, but often contain defects that reduce the intensity of light passing through the protective window
Even with materials that do not have any absorption in the visible region of the spectrum, there are reflections at the surface of the protective window that lead to a decrease in transmission
This is especially a problem with low-contrast displays because the information reproduced by the display array cannot be adequately discerned by the viewer due to the low light intensity

Embodiment Construction

[0253] figure 1 The first structural embodiment of the 2D element shown has a carrier 1 as a second functional layer in the form of a polymer film; the adhesive coating 2 is an acrylate pressure-sensitive adhesive; the first functional layer is An adaptation layer in the form of an anti-reflection coating 3; and a temporary carrier 4 which is a siliconized anti-adhesive film. The carrier film 1 is uniformly covered over the entire area of ​​one side thereof by the pressure-sensitive adhesive 2 . The other side of the carrier film 1 is provided with an antireflection coating 3 . The antireflection coating 3 is therefore arranged here between the carrier 1 and the surrounding medium. In order to prevent contamination and to prevent undesired adhesion to the release film, the entire area of ​​the adhesive 2 is covered with a temporary carrier 4 .

[0254] figure 2 The second structural embodiment of the 2D element shown has and figure 1 The structural embodiments shown have...

Abstract

A construction is presented for a unilaterally bondable, high-transparency, substantially two-dimensional element (2D element) having a support and an adhesive, which is used as a shatterproofing device for brittle 2D bodies.

Description

technical field [0001] The invention belongs to the field of applied polymer engineering and relates to exclusively unilaterally bondable, substantially two-dimensional elements (2D elements) comprising: a sheet-like first functional layer, a sheet-like second functional layer Adhesive coating in layer and sheet form, one of the two functional layers is designed as a support and the other as an adapter, the second functional layer has a parallel to its principal extent The first and second sides of the first functional layer are arranged on the first side of the second functional layer, while the adhesive coating is arranged on the second side of the second functional layer and are suitable for 2D elements and fragile Persistent bonding of 2D objects that, when broken, will be held together by 2D elements. The invention further relates to a bonded assembly comprising such a 2D element and a seethrough element, and also to a display system having such a bonded assembly and a d...
