Semiconductor and display-related productsWavelength Absorption and Color Compensation Adhesives for Optics
Supports various needs such as seamless display integration and protection from UV (ultraviolet) light.
It is a color correction adhesive that controls the transmittance of ultraviolet (UV) and visible light. With our unique dispersion and coating technologies, we have achieved a low-haze and no irregularities.
It is recognized for its high durability and appearance quality, and has been adopted for various applications such as seamless display integration and protection from ultraviolet (UV) light.
Product example 1Smoke adhesive
Feature
By dispersing black pigment in the adhesive, the transmittance of the adhesive layer can be controlled.
Highly regarded for its durability, our solution has earned long-standing trust in high-reliability automotive display applications.
Transmittance and film thickness can be customized to meet your specific requirements.
A seamless piano black design that integrates the interior, including automotive displays, has become a notable trend.
By using TOMOEGAWA's smoke OCA for automotive displays, the opening and bezel areas can be seamlessly integrated, creating a sense of luxury.
Application
Automotive displays, smart home appliances
Product example 2UV cut adhesives.
Feature
Displays such as digital signage and automotive displays are increasingly used in a variety of indoor and outdoor environments.
TOMOEGAWA's UV-cut adhesive protects displays from UV-induced damage caused by sunlight exposure.
The UV absorption range and film thickness can be customized to meet your specific requirements.
Water-applied types are also available for applications such as automotive and building windows.
Application
Window films for outdoor displays, dimming films, and more
Product example 3Total light transmittance 0% Light-Shielding / Appearance Inspection Black Adhesive Tape
Feature
This black adhesive tape for light shielding and appearance inspection suppresses back-side reflection when applied to film or sheet products, enabling clearer detection of defects such as streaks, unevenness, and foreign particles.
Its high light-shielding performance improves inspection contrast, helping to enhance both inspection accuracy and productivity.
Compared with conventional black ink coating methods, the tape can reduce process steps and improve the reproducibility of inspection conditions.
It can also be used as a light-shelding component for electronics devices.
Application
Sampling inspection of film products, light-shielding for electronics products
