• New Technology

Nano-Imprinted Light Guide Films are different from traditional injection molded Light Guide Plates (LGP’s) or Light   Guide Films (LGF’s) offering better efficiency of light use, lower profile display and lower cost manufacturing.

 

• High Resolution patterns

Nano-Imprinted onto thin, flexible translucent film substrates, light is guided in uniform or custom patterns creating various required lighting effects designed by computer software.

 

• High resolution Nano-structures

Uniquely allows for sophisticated control of light distribution to keys or buttons to maximize lighting efficiency.  Nano-structures are so small as not to be visible to the viewer.

 

• Roll to Roll, high efficiency production line

Provides very cost-effective and high quality manufacturing capability.

Light Guide Films: How they work.

The 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 Benefits

• 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.

Design

Light guide films are designed using customer CAD or other software to determine the size, pattern and layout of the microlens arrays.
