In-vehicle display | Anti-reflection film application examples
- Optical technology that supports visibility and safety of in-vehicle displays
- Dexerials' Anti-reflection film uses optical thin-film technology that utilizes light interference to provide drivers with a clear view that allows them to instantly recognize information, contributing to the development of in-car displays. Compared to conventional methods, there is less change in reflectance depending on wavelength across the entire visible light range, achieving more uniform and superior anti-reflection performance. This minimizes reflections on in-car displays under all lighting conditions, supporting safer and more comfortable driving.

Application
Reduces reflections from external light and interior lighting, improving visibility while driving
Dexerials has developed a proprietary "moth eye structure" that replicates the protrusion structure on the surface of a moth's eye at the nano level, significantly reducing light reflection on the display surface.
High durability and scratch resistance to withstand harsh in-vehicle environments
By forming a fluorine anti-fouling layer on the film surface using a dry vacuum deposition process, we have achieved surface properties that make it difficult for fingerprints and dirt to adhere.In addition, the abrasion durability has been improved by more than 40 times compared to our previous products, contributing to long-term product use.
Added shatterproof function
If the display surface is broken due to an impact such as an accident, the film on the surface will prevent glass shards from scattering, thereby helping to prevent injury to the driver and passengers and improving safety.
Product characteristics
Ultra-low reflection technology using moth-eye structure
Our moth-eye type Anti-reflection film almost completely prevents light reflection by forming protrusions on the film-like resin that are smaller than the wavelength of visible light (380-780 nm), just like the surface of a moth's eye. Furthermore, by layering thin films with different refractive indices in a multi-layer structure, the light interference effect is utilized to suppress reflection. While the reflectivity of regular PET film is around 10%, moth-eye type Anti-reflection film can reduce reflectivity to around 0-1%.
Excellent stain-resistant properties
The anti-fouling film is made of a special fluorine-based resin with excellent water repellency, so even if fingerprints or dirt get on the screen during use, they can be easily wiped off.
Excellent wear resistance
Because the anti-reflective layer is made up of a robust inorganic film formed using a dry process, no scratches were observed even under the rigorous test conditions of rubbing the screen 10 times with steel wool under a 2 kg load, demonstrating that it has higher scratch resistance than products manufactured using a wet process.
