MicroLens™ light extraction technology that provides up to 180,000 unique shapes per sq. in. MicroLens™ light extraction features are molded into both the top and bottom surface of the light guide. These MicroLenses result in a reflective matrix that directs light across the surface of the display in a very efficient and consistent manner.

Other light extraction technologies – printed, chemical or laser etched and V-groove – provide some of the benefits of MicroLens™, but each has limitations.

MicroLens™ VS OTHER LIGHT EXTRACTION TECHNOLOGIES

DIFFUSE LIGHT EXTRACTION TECHNOLOGY -- printed, chemical or laser etched Light is scattered in all directions (360 degrees) Brightness is low to medium for most applications Output angles cannot be controlled Non-transparent dots block a significant portion of light that is scattered downward from reflecting back through the panel and exiting the top surface
SPECULAR LIGHT EXTRACTION TECHNOLOGY V-GROOVE Benefit: High brightness Limitation: 2-D uniformity correction not possible
SPECULAR LIGHT EXTRACTION TECHNOLOGY MicroLens™ Benefits: 2-D uniformity corrections are possible High brightness Optical features are transparent Normal reflection and transmission percentages are roughly 60% and 40% respectively Light is reflected and transmitted from the optical features in a specular manner The angles at which light is emitted from the light guide can be controlled
