Optical performance
Environmental test results
Eldim optical data taken on standard production 35.8 cm (14.1 inch) notebook PC, TFT display, with wedge light guide with single CCFL and standard industry back reflector.
Testing
The polar plot measurement values indicated on the left
were obtained through testing crossed Vikuiti BEF III
with a cover sheet and a bottom diffuser with a TN type LCD.
We performed the test using our standard backlight and
production films.
We measured the power to the backlight and measured
the axial luminance and expressed the result as Axial Luminance
Nits/Watt. Similarly, we measured the integrated intensity and
expressed the result as Integrated Intensity (Lumens/m
We believe these measurements and reporting techniques
clearly and concisely represent the benefits of the Vikuiti
BEF III while providing results that are readily comparable
to other filmstack combinations.

Nominal film properties
The technical data for the products described are typical, based on information accumulated
during their life, and are not to be used in the generation of purchase specifications which
define property limits rather than typical performance.
Percentage increase is defined as increase over displays without film.
*Vikuiti BEF III brightness increase depends on the backlight material composition, design and
overall lighting efficiency.
