Dimming film that creates a private space
Light Control Film
The light control film is based on GHLC technology realized by DNP's converting technology and sheet processing technology. Electronically controlling the shading and transmission enables the film to protect privacy and have a seamless design.
For many companies, remote working has been introduced as the new normal. In recent years, instead of working from home, there has been a proposal for "working in your car" that utilizes the inside of a car as an office. However, one of the challenges of working in a parked car is worrying about your surroundings such as passing pedestrians. DNP's Light Control Film is a single electric switch solution to switch the interior of the car into a private space.
Switchable film using GHLC method （GHLC：Guest-Host Liquid Crystal）
■ "Neutral black" creates a sleek aesthetic that allows a smooth transition to interior design
■ High-speed drive allows instant switching between "glare" and "transparent" (≤1sec.)
■ Color can be customized with pigmented dyes
■The film based system allows for high flexibility, shape forming, and can follow curved surfaces.
■ Low voltage requirements contributes to "energy savings" that affects the cruising range of EV vehicles (≤30V)
■High transparency realizes a glass-like appearance
■ Divided drive in the film improves design
What is Neutral Black？
Other technologies such as EC and SPD have a green or blue hue.
GHLC technology can achieve "Neutral Black" that creates a sleek aesthetic and seamless design integration into a car.
About Divided Drive（Segmentation)
Divided drive（Segmentation) is a drive method that can individually control a specific area in the electron shade by patterning the transparent electrodes. You can recreate the same optical effect of opening and closing curtains and blinds by electrical control.
Ideal for protecting privacy and seamless design
■ For in-vehicle use
・ Replace mechanical curtains for weight reduction and save space
・ Smart glass integration for sunroofs and windowpanes (added segmentation function)
・ As anti-glare functions for various applications such as side mirrors
■ Other than in-vehicle
・ For improving the contrast of transparent displays
・ For windows and doors for architectural market
In April 2017, DNP started collaboration with "Alpha Micron (AMI)",
which conducts R&D of high-technology Liquid Crystal applications, in the LC dimming film business. In August 2018, we established a joint venture "AKARI, LLC" as a sales window for dimming films that use guest-host LCs.
