Revolutionary Smart Glass Technology

More than Visual Comfort and Energy Savings

Affordable Smart Glass within Reach

At eLstar, we create adaptive smart glass driven by Electrophoretic Light Emulator (ELM) technology. With this ultra performing ELM technology, we control the amount of solar energy that enters a building or vehicle and allow solar heat to enter when it's needed and to absorb the energy when it's unwanted.

The result is substantial energy savings and increased visual comfort that’s affordable.

eLstar...What's in the Name?

Why “eLstar” Dynamics? Our name refers to the ability of our technology to control light, or lightness. Lightness is measured on the L* scale and represents the human ability to perceive light.

What does the L* - eLstar – symbol mean?

L* - eLstar - is the symbol of perceptual lightness. L* values are luminosity indices, expressed as numbers from 0 to 100. Unlike machine transmission, L* accommodates how the human eye adapts to changes in light.
