Privacy Filters

There are a number of applications for displays where privacy for the viewer is required such as an outdoor privacy screen in an ATM or kiosk. A simple and effective solution for a computer privacy screen is to laminate a view control film, such as 3M privacy film, into a screen. This film will control the position from where the display can be viewed. There are two options of view control film available when considering the construction of a privacy screen both of which can be easily incorporated into a laminated screen.

Light Control Film (LCF)

A simple analogy for privacy film is to imagine Venetian blinds. If you were to stand at 60' to the front of these blinds your view would be blocked by the sides of the louvers. Standing in front of the blinds allows you to see straight through the individual louvers.

The film is a very soft material and it is recommended to laminate it between glass or polycarbonate in order to avoid any scratches which might impair the image quality. 3M privacy film is laminated between glass or polycarbonate which may have anti-reflective or non glare finishes.

Blur Film

Blur film works by dispersing the incident light at particular angles and transmitting it at all other angles. The appearance therefore changes from translucent to transparent depending on the angle from which it is viewed.
