Light Guide Films: How they work.

  Light Guide Film Structure  

The Nicrotek Light Guide Films (LGFs) are designed for effective use of LED edge light sources.   Light from the LED sources is internally reflected down the length of LGF to the various viewing areas.  The Localized Micro-Lens Arrays  redirect light out of the film to the viewer only where it is needed (to each logo, image, key or button) by layout design.   This new technology patterning allows light to be efficiently and uniformly directed where light is desired in a very low profile film. 


Light Guide Film Examples

Light Guide Examples
  • Very efficient use of light only to areas to be illuminated.   Patterns of MicroLenses areas designed by Customer software such as CAD or other standard design software.  
  • More Efficient use (and reduced numbers) of LED sources
  • Very Thin Form Factor.
  • Roll to Roll Film Manufacturing for Low Cost
  • Software Designed Patterns for Precise Light Control.

Side Emitting Type LED Solutions

  Side View LED Light Guide FIlms

Popular for most of the middle and high end phone keypads, Achieves higher brightness and better uniformity compared with top emittng LED types.


Top Emitting LED Solutions

  Top View LED Light Guide Films

Suitable for low end phone keypads: It can cut LED quantities, saving power consumption, compared with traditional direct Top emitting  LED solutions.  Also, it can achieve better uniformity than direct Top view LED light sources..
