Display ProductsWavelength absorption and color compensation adhesives for optics

Available for color adhesives for seamless purpose, UV cut adhesives, NIR cut adhesives and etc..

Optical adhesive films are Our adhesives that give each layer of various displays a function according to your needs. While maintaining a high degree of transparency, TOMOEGAWA's advanced blending technology fuses light-controlled microparticles within the film.Also, precise coating technology allows for uniform coating. It is possible to improve the display quality and functionality. We provide color adhesives that control the transmittance of ultraviolet (UV), visible light, and near-infrared (NIR) light according to your needs.

We have a variety of adhesives that are ideal for a variety of applications such as protecting functional materials from UV rays, adjusting the color of displays, and preventing equipment from malfunctioning due to near-infrared light. Also, TOMOEGAWA's coating technology enables a uniform coating.
