Anti-reflection films for various types of displays

Antireflection Films (Surface Treatment Films)

Antireflection film is an optical film to be laminated on the front surface of a display in order to minimize reflection of light from outside and of viewing person. Various types of antireflection films can be provided for different applications, examples of which include low reflection (LR) film that realizes the excellent antireflection property, antistatic performance and higher contrast; antiglare (AG) film that controls reflection with excellent antiglare properties.
In addition, such film effectively protects the display by reinforcing physical properties, durability and anti-soiling.

The principle of preventing light reflection (LR)

The film structure is designed so that the lights reflected on the antireflection layer and the boundary face of the base film have the same amplitude with the opposite phase. Reflection is restrained as two different lights are negated by interference.

The principle of preventing light reflection (LR)

The principle of preventing screen glare (AG)

Within the hard coated layer that was formed over the base film, microparticles whose light refraction factors differ from that of its resin are deployed. As such particles disperse external light, glare on the screen is diminished.

TOPPAN's approaches

A wide range of AG and AGLR films for PID, automotive and industrial applications.

Films having a different haze of 1% to 60% covering almost all products on the market

Continuing development of highly functional CHC films for compact applications

Highly functional films are available; thin base materials, high scratch resistance, surface resistance control, UV protection, bending-resistance, surface contact angle (for lamination, antifouling), low moisture permeability, etc.

LR designs tailored to high-spec panels

Films achieving a reflectance of 1% up to 0.3%, reflective hue control matching panel colors, and surface resistivity control
