Smart film

SMART VU FILM, known as switchable window(glass) film, is an electronic

component that can actively adjust the penetration rate of solar light and keep the privacy in your own space.


is a new material that adjusts the penetration of visible rays according to the

presence or absence of electricity.

- In the absence of an electronic field, the droplet director is randomly aligned and the refractive index of the droplet is mismatched with that of the prepolymer which

causes the light to scatter.

- In this state, the film can be switched to an index matched and transparent state when the electric field which align the droplet director parallel, is applied.

Applied Functions:

- Privacy Function

- Rear Screen for Display

UV Protection window

- Infrared Ray Block

- Partition
