Vikuiti
How it works
Vikuiti
shows a conventional backlit system emitting P1 and P2 light. A
typical polarizer absorbs P2, but Vikuiti DBEF reflects P2 into the
backlight, where it is recycled into P1 and P2 light. With Vikuiti
DBEF, more P1 light is available to be transmitted through the LCD,
increasing on-axis illuminance by up to 60% for a slab backlight and
up to 97% for a wedge light guide. Vikuiti DBEF achieves additional
on-axis illumination performance in a wedge backlight display by
redirecting available light to the viewer.
