View control film

View Control Film or VC-Film is an optical louver film of alternating optical clear silicone rubber and black silicone rubber layers.

Sheets of such alternating layers are positioned between PC or PET films to provide an optical filter.

The highly transparent silicone rubber allows VC-Film to be used in following functional applications:

  • Positioning the View Control Film in front of a display panel with louvers vertical, the film will make the image on the display visible for the user of the display only. People positioned besides the user will not see information on the display. For tablet style handheld devices, filters can be stacked as cross filter to shut lights in all directions.
  • anti-reflection filter for backlit functions in cars

    Positioning the View Control Film in front of a display panel or on a backlit switch, the film will allow the light to go towards the driver. The backlight will be blocked in the direction of the windshield or side windows and stop the mirror image while driving at night. The View Control Film allows cardesigners to freely position functions in the car without requiring special designed roofs to avoid reflections.
  • light shutter for industrial light sensors
to avoid disturbing effects of light curtains mounted on industrial machines, View Control Film can block light in undesirable directions.

VC-Film is made to custom design and requirements although certain view angles and louver angles are standardized to ease the supply. Special view angles, louver angles, louver colors and constructions are available on request.
VC-Film can be used on top of touchpanels based on capacity touch reading.
