AGC Inc. has announced its light control glass, “WONDERLITE (TM) Dx,” has been adopted for the panoramic sunroof of Toyota's new Harrier, launched for sale on June 17, 2020. When used as vehicle exterior glass, this product boasts the world's fastest response (*1) time, enabling instantaneous control of light transmission. This marks the world's first-ever adoption (*1) of the product in a mass production vehicle.

AGC's light control glass WONDERLITE (TM) Dx comprises a specialized film encapsulated between layers of interlayer in laminated automotive glass. By softening the sun's glare in dimmed mode (opaque state) and providing a wide sense of openness in transparent mode (clear state), the product realizes a vehicle interior that allows pleasant light to pour in from the panoramic sunroof whenever the user wishes.

Technical Overview of Light Control Glass “WONDERLITE (TM) Dx”

-Structure

Image3: https://kyodonewsprwire.jp/img/202006170973-O4-de68Lr14

Light control glass is composed of a specialized film (*3) encapsulated between layers of interlayer in laminated automotive glass. The film contained within is packed with a special material too small to be perceived by the naked eye. Around 99% of ultraviolet rays are blocked in both transparent and dimmed mode (*4).

Notes:

(*3): Special film made by Kyusyu Nanotec Optics Co., Ltd.  

(*4): Based on ISO9050 standards

-Mechanism

Voltage is used to control distribution and orientation of the special material in the film encapsulated between layers of interlayer in laminated automotive glass, enabling instantaneous switching between transparent mode and dimmed mode.
