Laminated Windows and Displays

  There are 7 main product groups for laminated windows and displays. A list of laminated screen filters are below.

Emi/Rfi Shielding      EMC Windows      Security Screens     Contrast Enhancement Filters    

Privacy Filters     Polarizers        Infra-Red Band Pass Filters

 

A fully laminated window consists of two outer substrates with a sandwich construction of alternating layers of adhesive and other elements such as mesh and optical films.

Following the assembly of the adhesive and substrate in a clean room the window are subjected to a heat and pressure process in an autoclave.

Optical laminating

The optically matched adhesive layer provides a fully laminated structure in which the entire surface between layers is bonded. There is no limit to the number of layers or materials that you can incorporate into a laminated window, providing they are optically and mechanically compatible.

The adhesive layers used on laminated windows are 0.38mm or 25mm thick.

Substrates

Fully laminated windows allow a wide range of substrates. The standard options are:
Glass
Polycarbonate
Acrylic
The appropriate substrate is selected by matching substrate properties to end-use requirements and cost.

Adhesives

The adhesive layers are 0.38mm or 0.25mm thick. At least one layer is required between each solid component in the laminate.
The operating and storage temperature envelope is -40 to +75C. Short term exposure to temperatures from -50 to +85C can be tolerated

 

  Emi/Rfi Shielding

  Laminated windows can incorporate either a layer of metal mesh or a conductive coating to   provide emi shielding for a display. There are a variety of meshes and terminations, which are discussed, in greater detail on the related page.

  Security Screens

  A laminated window has approximately the same impact resistance as a toughened piece of glass of the same thickness. It offers an impact resistance equivalent to BS6206:1981 which specifies the requirements of glass structures. A significant added benefit of laminated glass windows is the safety aspect. If a laminated window were to shatter the glass shards would adhere to the adhesive layers rather than scatter out.

  Contrast Enhancement Filters

  The principal application of colour laminations is in contrast enhancement filters. Colours and tints can be added to any type of window by use of a coloured substrate or a tint layer. Optical filter's tint layer technology allows a wide range of options and where necessary, we can selectively colour different areas of a window to match multi-function display requirements.

  Privacy Filters

  View control films are an important addition to laminated windows used on ATMs and public information displays. These privacy filters control the positions from which the display can be viewed.

  Polarisers

  Circular and linear
