Louver Privacy
A louver privacy film can be easily incorporated into a touch screen lamination to form a computer privacy screen. Standing in front of the screen allows you to see the display through the individual louvers, if you were to view at an angle of 30' or great from the center line, the image on the screen would be blocked by the sides of the louvers. A simple analogy for the privacy film is a Venetian blind.
Typical applications for privacy displays are ATMs and public kiosks. A 17" diagonal screen is the maximum size available. The technique is suitable for indoor or outdoor privacy screens.
Blur Privacy
Blur privacy film functions by a microstructure that scatters the incident light from particular angles and transmits it at all other angles. The appearance of the touch screen display therefore changes from a blurred image to a clear readable one depending on the angle from which it is viewed. Blur privacy filter benefits include greater light transmission than the louver film, together with larger sheet size at a lower cost. However the effectiveness of the filter depends upon the distant set from the display and, unlike the louver film, the image is only distorted and does not fully black out.
Transparent Heater
To defrost and /or maintaining an optimum screen temperature, a transparent heating element can be bonded to the rear surface of the touch screen. Maximum available size is a 17" diagonal screen.
The heater is able to maintain 20'C +/-2'C at the LCD with an outside temperature of -50'C and over temperature gradients of 3'C/minute.
NIR Radiation Control
Direct sunlight heating can be controlled by the addition of a Near Infra Red filter. Whilst providing a high level of visible light transmission (>70%) the NIR filter blocks 90% of Infra Red at 850nm increasing to 95% from 950nm.
EmiClare EMI Shielding
EmiClare is an EMI shielding mesh designed for optimum optical performance with a high level of shielding effectiveness at both high and low shielding frequencies. Military, test equipment and medical markets are typical applications requiring extra EMI shielding provided by incorporating EmiClare mesh into a touch screen monitor lamination.
