Film Enhancements

  • Anti-Reflective Films – AR films or coatings can be incorporated into various places in the product construction to reduce light reflections at interfaces with air.  The reduction of the reflected light will enhance the contrast and visibility of the display image by reducing the intensity of reflected ambient light back to the user.
  • Privacy Films – These films can be incorporated into the sensor construction to narrow the viewing area of the display to the user directly in front of the display.  This can be helpful to eliminate surrounding individuals from seeing confidential information in public areas.
  • Anti-Microbial Films – These films can inhibit the growth of microbes on the surface of the material.  This can be useful in public use applications where many different people are touching the screen.

EMI Shielding

EMI Shielding is frequently used in applications where the user needs to contain EMI noise inside the unit to pass radiated emissions requirements or to prevent EMI noise from entering the unit in order to pass susceptibility requirements. Shields of various conductivity and shielding effectiveness can be incorporated into the sensor structure to aid in controlling EMI from entering or leaving the unit.
