How FLEx Technology Works

FLEx has reinvented the light guide to solve the problem of inefficient backlights and to bring light to new places.


FLEx Technology

FLEx has developed proprietary technologies to convert thin plastic film into an efficient and powerful light source for a wide range of applications, from the displays on our electronics to the light fixtures in our homes.

A “light guide” is a common method of lighting the phones, tablets, laptops and televisions we use every day. Light is inserted into a sheet of plastic, which then “lights up”.  In backlit devices, transmission through the pixels limits the efficiency of the display resulting in wasted light and power. With LED front light technology, no light goes to waste which in turn saves power. In the simplest terms, FLEx has re-invented the “light guide.”

FLEx technologies use an ultra-thin, flexible light guide that can be placed at the front of a reflective display stack. It works with sunlight and uses off-the-shelf LEDs, making it efficient, smart, and easy to integrate. The ultra-thin, invisible light guide can conform to virtually any form factor. Leaving you with an elegant display that delivers radiant colors (in direct sun), uses significantly less power, produces less eyestrain and lasts longer than OLEDs. It’s a smarter way to source your light.
