Wearable Devices

Stop fighting the sun and your battery for power

Frontlit Smartwatch Wearable Device

Reflective, Frontlit LCD Displays

Wearable devices may be small, but if they're not frontlit and reflective then their appetite for power is anything but. As the display stack gets smaller on wearables and the use moves outdoors, you arrive at the precise reason why FLEx reinvented the light guide.

Our thin optical film delivers light to your display when needed through our reflective display technology. The LED front light panel lets the sun do the job whenever it can, providing a brilliant user experience that draws less power. Your device gets increased energy efficiency and a longer battery life in any setting.
