Enhanced mechanical and environmental durability are required for film that is used at the surface of a touch panel. Moreover, display function in order for LCD to have better visual quality is also required for film material. By using our very own technology obtained from development of high functional film for touch panel, GUNZE developed high functional film intended for not only touch panel but for other display devices.
Suitable for bonding with ITO film from its characteristic of acrylic acid free and corrosion free.
Inhibition of "Cloudy" phenomenon under condition of high temperature and humidity maintains high transparency.
UV cut function is available as an option.
|Subject||Item||Test Method||Unit||OCA Thickness (μm)|
|Total Light Transmittance||JIS K7361-1||%||92.0||91.9||91.8||91.8|
|Adhesion (After Environmental test *2)||JIS Z0237-2000||N/25mm||12.5||12.7||13.1||14.4|
*1 : Measured the structure of 0.7mm glass + OCA
*2 : Value after the environmental test of 60 degrees / 90% R.H. / 240 hours
- Suitable for bonding with ITO film because of acrylic acid free
- Inhibition of "Cloudy" phenomenon under the condition of high temperature and high humidity and have excellent for the adhesive stability
- Excellent for the unevenness-following to decorative printing parts
- UV cut function is available as an option
- Bonding touch panel and cover glass
- Bonding touch panel and LCD
- Bonding electrode glass or films
- Bonding glass and anti-scattering film
Fingerprint attached on the surface of film is less-visible and easy to wipe off. This is the characteristic of GUNZE hard coat film which prevents visual depression caused by fingerprint. We have 2 types of film in our line up. One is "Lipophilic type" which has characteristic of making fingerprint attached on the surface of film less-visible and easy to wipe off. Another is "Slipping type" which has characteristic of excellent protection against fingerprint and extremely smooth finger movement. Both types have characteristic of high hardness, low rainbow (or reduced interference stripe), and may be supplied with OCA as an option.
By optimizing the design of Anti fingerprint hard coat film has reduced the interference stripe or appearance of rainbow which was an issue for existing hard coated film.
- Prevent visual depression caused by fingerprint
- Have high scratch resistant with high hardness
- No raibow appearance having reduced interferance
- On the top surface of touch panel or application such as mobile phone.
Inhibits reflection of light and improve the visibility.
Optical and material design suitable for capacitive type touch panel. May be supplied with OCA as an option.
- Improve visibility by controlling reflection of light from the sun and LCD.
- Have excellent adhesion with low reflective surface and OCA.
- Back surface of Projected Capacitive Touch Panel
The maximum pencil hardness is 9H without hard coating. Optional function of anti-finger prints, anti-reflection, smooth touch are able to apply. Also superior to environmental resistance. HD film is the best solution to cover film for various mobile devices.
- Surface pencil hardness is maximum 9H
- Clear type and anti-glare type are available
- Anti-finger print, anti-reflection, and smooth touch are able to apply.
- Cover film for smartphone and tablet etc.
- Touch panel substrate for high durability solution (car navigation etc)
OC film has high optical characteristics, heat resistance and dimensional stability. Both isotoropic film and retardation film are available. (COC:Cyclic-Olefin-Copolymer). They are also able to apply to sunglasses-approved device which is currently grate demands.

- High optical characteristics. Transmittance 92%, Hase < 0.2%, retardation <5nm.
- Dimensional stability. Heat shrinking rate <0.10%, water absorption rate 0.01%
- Large size and thinner film are available
- Various kinds of film are available by adding function. Extension film, hard coating, ITO film.
- ITO film for touch panel
- Substrate for optical filter
- Substrate for flexible display
