In this paper, we searched the parameter of BEF (Brightness enhancement film) using
commercial FRED server for backlight module. The pattern analysis was carried out to
understand its characteristic. The current structures used in LCD backlight are
double-layer BEF. In addition, BEF of 3M takes the lion¡¦s share. But this may increase
the thickness and cost of backlight module. In order to avoid those disadvantages, we
tried to design single-layer BEF and characterize the effect through parameters study by
using FRED software simulation. pyramid-shaped microlens array of BEF was
constructed. Therefore, the effect of the variation of the structure parameters can be
analyzed, such as prismatic degree (£c), prismatic structure on the brightness
enhancement. It can be found from the result of simulation that the changes of the
prismatic degree (£c) of 85 degree influence the brightness enhancement the most.
