Nanoimprinting is a precision transfer technology that is used to form nanometer-sized structures on the surface of a base material. By changing the shape of the nanostructure, we can create products with useful optical properties. (Fig. 1)
Using optical simulation and evaluation technology developed through our work in manufacturing optical films for LCDs, we're designing a variety of optical products. We're moving forward with development of products that include functional films that greatly improve light extraction in OLED lighting, and anti-reflective films that virtually eliminate glare, as well as inorganic wave plates and anti-reflection films for OLED displays that rely on the principle of form birefringence.
In addition to developing original JXTG products, we're also engaged in contract manufacturing of soft molds and nanoimprinted products.

JXTG's Nanoimprinting Technology
In film imprinting, a film substrate is coated with a UV-cure resin, then pressed against a patterned metal roll to form a nanometer-size structure (Fig. 2). The use of a roll-to-roll process results in high productivity.
We're working on imprinting with inorganic materials on glass substrates (glass imprinting) in the hope that nanoimprinted products could be used in a wider variety of applications. Because the products are made of only inorganic materials, they outperform conventional film products in terms of heat and chemical resistance. They can be manufactured in sizes up to 400 x 500 mm, and enable continuous processing based on roll-to-roll technology.
