Product category: Switchable glass/electrochromic glass/smart glass


SMART VU FILM, known as switchable window(glass) film, is an electronic component that can actively adjust the penetration rate of solar light.
This is a new material that adjusts the penetration of visible rays according to the presence or absence of electricity.

PDLC film(glass) enables a  film to be transparent or opaque in both normal and reverse mode depending on ON / OFF operation using electrical signal.

PDLC mixture is laminated between two transparent conductive coated PET or glass. PDLC mixture is consisted of droplets of liquid crystal which contains bipolar alignment. This mixture is dispersed in a matrix prepolymer binder.

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 of the PDLC can be switched to an index matched and transparent state when the electric field which align the droplet director parallel, is applied.

BS 210

BS 210 is a ink-coating product that provides waterproof and rust prevention at the edges of mirror.
The coating time is dramatically reduced compared to the edge coating method using existing IR and paraffin.
Hence, it is designed to improve productivity by simplifying the production process and minimizing the defective rate.

BESTROOM’S OCR (Optical Clear Resin) is a product with high transparency and excellent adhesion and weather resistance.
Adhesive with harmonized refractive index improves the visibility of the display and reduces blur in bright external environments (ie. under sunlight).
OCR is specially designed for applications requiring transparency and invisible adhesion.
UV-curable optically transparent resin improves the brightness and clarity of liquid crystal displays, monitors, DID screens and kiosk panels by preventing the yellowing and improving the visibility of the LCD.
UV curable resin is used to bond various substrates such as glass, PET, and ITO with optically cured resin.
