Free technical materials available! Reflectance approximately 0.3%! Enhancing the luxury of automobiles with 'Piano Black'.

In recent years, automobile users have been seeking stylish interior designs that match the excellent exterior designs of their vehicles. Particularly among those who prefer luxurious designs from Europe and the United States, there has been an increasing number of people who favor interiors with a "piano-like deep glossy black" (piano black). This makes the appearance of displays, which are used for various purposes, particularly important. Recently, many displays have been utilized in car navigation systems and other applications. On the other hand, displays that can express a beautiful "piano black" that harmonizes with the surrounding interior, such as the dashboard, during both power on and off have been difficult to achieve due to technical hurdles. Our company has been advancing the research and development of "anti-reflective films" that enable displays with a luxurious "piano black." The foundation of this research is the anti-reflective technology used in high-grade PC monitors and tablet PC displays. This black is achieved by not reflecting light. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

basic information

【Anti-Reflective Film that Creates a Sense of Luxury】 When a spoon is placed in a glass of water, it appears to bend at the surface due to the difference in the refractive index of air and water as light passes through them. The anti-reflective film applies this principle by layering multiple nano-thin layers with different refractive indices, allowing the boundary reflected light to cancel out the surface reflected light, thereby reducing the reflected light that reaches the human eye. The challenge in development was that the concept of the anti-reflective film for monitors could not achieve a "beautiful black with transparency" as it was. In the case of a car interior, where the viewer is rarely looking straight on and the light enters from various angles, even a layer just a few nanometers thick can result in subtle changes in the distance light travels through it. At Dexerials, in response to such needs, we utilized simulation technology to newly design the anti-reflective layer and succeeded in commercializing anti-reflective film for automotive displays by manufacturing it with precision. *For more detailed information, please refer to the related links.
