Japan's GEOMATEC utilizes surface treatment technology and ecological simulation technology (bionic), using the excellent mechanism of the moth simulants of the compound eye "moth-eye structure". Through the unique transfer board manufacturing technology jointly developed with Tokyo University of Science and Mass production of nano-scale fine moth-eye structures on roll film.
The newly developed Moth Eye Type film G. Moth® has both ultra-low reflection properties and antiglare characteristics.
The moth-eye effect means that the refractive index of the light wave will show a continuous change in the gradient refractive index on the surface of the moth eye, so that most of the light will be absorbed, but only rarely reflected. G. Moth® of GEOMATEC company is a kind of Anti-reflection films that hardly cause reflection are currently used for digital billboards or car displays used in stations.
When G. Moth® is pasted on both sides of the glass, the reflectivity is only 0.5% (the reflectivity in the case of ordinary glass is about 4%), which can suppress the reflection of light and the image to the limit.
The G. Moth® product developed this time has an anti-glare structure added to the moth-eye structure. When viewed at an inclination angle of 50 °, the reflectance is only 1% or lower (at a wavelength of 550 nm), so it is very Easy to see in a wide range.
Generally, moth-eye films with uneven structures are easily contaminated, but the moth-eye films of the company have super waterproof and oil-proof properties as well as excellent anti-fouling properties.
G.moth® also increases the surface hardness and stain resistance. Even after repeated wiping, the moth eye structure does not change significantly. The fine protrusions on the nano-sized surface (moth eye structure) can produce a lotus leaf effect similar to the lotus leaf surface. Hydrophobic.
G.moth® products have a maximum width of 600mm and can be used in 45-inch TVs, digital signage, window display cases, art galleries, and car displays.
According to data, Japan GEOMATEC company was founded in September 1953, dedicated to cultivating vacuum coating technology, and began to use ITO to manufacture transparent conductive films in 1972.
The company can choose from a variety of coating methods and conditions according to customer needs. The transparent conductive film (ITO film) provided has high transparency, low resistance and excellent etchability. The company also uses low-temperature and non-thermal coating methods to minimize damage to heat-sensitive substrates such as color filters and resins. GEOMATEC's transparent conductive film is widely used because it can adjust the film thickness and resistance.
Through continuous research and development of technologies, GEOMATEC has involved from anti-reflective and reflective films manufactured by light-controlled multilayer optical films to ITO and metal films used in mobile phones and car navigation equipment, which has greatly expanded the application range of vacuum coating It integrates coating technology with the technology and knowledge of other industries.
