Brightness Enhancement Films
• Increases forward brightness
• Increase brightness or reduces power
• Enhances uniformity and backlight defect hiding
• Increases wide angle luminance
Uniformity + Color Enhancement Films
• Reflective polarizer + geometric enhancement
• Differentiated diffusers
• Enables reduction in number of films
• Enables light source removal beyond
traditional uniformity limits
• Increases brightness compared to reflective
polarizer alone

Key Enablers
• DBEF recycles light normally
absorbed by the LCD
Definition
• DBEF-Qv3: New on-glass
reflective polarizer solution
with matte surface
• BEF3-7T- BEF films increase
brightness by redirecting
light on axis
White
Reflector
• D4-400i: Integrated DBEF
and prism enables both
brightness thru light recycling
and redirecting light on axis in a
single film
• QDEF: Enables energy efficient
high color gamut. Also functions
as the bottom diffuser.

between two sheets of reduced-haze
polycarbonate.
Highest efficiency backlight reflective polarizer
suitable for large sized applications with luminance
demands.
DBEF-Qv3
Reflective polarizer delivered on the rear
display polarizer.
High brightness solution integrated with the LCD for
increased robustness.
DBEF-LS
Reflective polarizer between two
stiffening and customized diffusing
sheets of polycarbonate.
Reduced sparkle backlight reflective polarizer
suitable for high resolution applications with
luminance demands.

gain diffuser and anti-stat matte rearside coating.
Displays that require high efficiency and uniformity.
Can be used with or without an additional prism
film. Edge and direct lit application.
D5-520
Intended as a single film solution for edge and
Reflective polarizer with integrated
applications. May be combined with
microlens structure for maximum gain. direct-lit
additional diffuser or BEF for increased brightness.
One Pol
Reflective polarizer with integrated
absorbing polarizer functionality for
application directly to the glass of the
LCD panel.
Intended for large sized displays with high demand
for lower performance and component integration.
Can be used without any free floating films for
a direct-lit or may be combined with additional
diffuser or BEF for increased brightness and
contrast.
D4-400i
Reflective polarizer with integrated
prism structure for maximum gain.
Intended as a single film solution for edge and
direct-lit applications. May be combined with
additional diffuser for maximum performance.
