Toppan Printing : Kyushu Nanotec Optics and Toppan Printing cooperate in the liquid crystal light control film business

-Background

Liquid crystal light control film is a film that can control light travelling through the liquid crystal, switching instantly between transparent and opaque with the switching on and off of electrical power. The film has light blocking as well as infrared/UV resistance properties and can also function as an image projection screen.

In the future, liquid crystal light control film is expected to be used in the construction of offices and public facilities around the world, responding to energy saving needs. In summer, heat shielding or cutting functions can suppress rises in room temperatures, while in winter, energy bills could be reduced by providing natural light. In addition, the film can be used as a projection screen or signage for commercial facilities, etc. and contribute to visual/spatial presentation using glass windows. The new type (reverse mode), which is transparent when the power supply is turned off, is expected to serve increasing needs for energy saving and safety, especially in the automotive and aerospace industries.

-Features of liquid crystal light control film

1）World's first liquid crystal light control film which is transparent when power supply is off has been developed.

In addition to the normal mode of transparent when power is on, a reverse mode of transparent when power is off has been developed. This new type will support automobiles and other means of transportation by contributing to safety.

2）Easy to apply to curved surfaces or glass

Ultra thin film of 0.1mm has been produced and can be applied to curved surfaces or glass.

3）Gradation from opaque to transparent possible

Gradation from opaque to transparent based on changes in voltage has been achieved. This has not been possible with other types of light control film.

4）Energy saving function

More than 65% of infrared light is cut when the film is in its opaque state, enabling outstanding energy saving.

5）Low voltage / energy consumption

With a driving voltage of 12-60V, lower voltage and energy consumption than other light control films has been achieved.

6）More options in terms of design

As a film, it can be cut into any shape using scissors or cutters, and slits or holes can also be made easily. A wide range of color variations, including black, are under development.

7）Large sizes available

A width of 1,200mm is possible, and the film can be shipped in roll form to respond to needs for larger sizes.

-Example of use

・Windows and sunroofs of automobiles and aircraft

・Windows and partitions for housing, offices, and public facilities

・Projection screens and signage for commercial facilities, shops, and event venues

-About Kyushu Nanotec Optics

Kyushu Nanotec Optics was established in 2004 centered on liquid crystal light control technologies.

The company manufactures and sells industry-leading liquid crystal light control film with excellent heat shielding properties, speedy response, low voltage requirements, and high-precision optical screen functions. The company is now garnering attention for its superior technologies, and for successfully developing and commencing volume production of the world's first 'reverse mode' liquid crystal light control film (transparent when power is off).
