Global Lighting Technologies` ( http://www.gtlhome.com ) MicroLens™ typically provides a unique "transition" area that spreads the light uniformly, extracting light precisely at each point across the panel. MicroLens™ light guides are developed in a very thin package, with mechanical holding features that can be designed into the backlight.
This allows chip-on-glass (COG) or chip-on-flex (COF) LCDs or the entire display assembly to be mounted into the host application. This can reduce part count and assembly and material costs.
MicroLens™ enables light extraction features to be designed in a controlled, progressive process, where iterations can be reduced and repeatability from mold cavity to mold cavity is exceptional. When compared to printing, chemical or laser etch, stamper and V-groove processes, MicroLens™ typically improves optical performance in addition to being more repeatable.
Only MicroLens™ offers high-precision control of all six of these variables:
size; shape; depth; population; randomization; orientation or angle/rotation.
