The integration of high-performance cover glass into TFT OLED displays has become indispensable for automotive and industrial devices. In car navigator applications, the cover glass typically employs Gorilla® Glass, with alternatives such as AGC Dragontrail, Panda Glass, aluminosilicate glass, soda lime glass, acrylic (PMMA), or polycarbonate (PC). Thickness ranges between 1.8 mm and 15 mm, ensuring compatibility with diverse structural needs. Advanced surface treatments such as anti-glare (AG), anti-reflective (AR), and anti-fingerprint (AF) coatings significantly enhance usability under challenging lighting conditions. With impact resistance up to IK6–IK10, optical transmittance around 90%, one-color black silkscreen printing, and chemical tempering, the material provides both durability and clarity. Optical Clear Adhesive (OCA) bonding ensures high-quality lamination, while antibacterial and UV-resistant treatments extend service life. These properties make customized solutions viable for in-vehicle smart devices, center consoles, navigation units, EV charging stations, and industrial control equipment.
Choosing the right substrate is critical for balancing durability, optical performance, and cost. Gorilla® Glass remains a premium choice for automotive-grade applications due to its superior hardness and impact resistance. Meanwhile, AGC Dragontrail and Panda Glass provide competitive alternatives with similar mechanical robustness. Aluminosilicate glass is preferred for its thermal stability, while soda lime glass offers cost efficiency in less demanding environments. For lightweight or impact-prone designs, polymer substrates such as PMMA and PC serve as reliable options.
The glass thickness range of 1.8–15 mm allows engineers to tailor solutions to different end-use scenarios. Thicker panels contribute to enhanced IK ratings (IK6–IK10), improving resistance to mechanical shock and vibration, which are common in both automotive and industrial applications.
Surface functionalization is essential for visibility and cleanliness.
AG Coating diffuses incident light to minimize glare in sunlight.
AR Coating reduces reflectance, improving contrast and readability.
AF Coating prevents fingerprint accumulation and eases cleaning.
OCA bonding technology enhances optical clarity by eliminating air gaps, reducing internal reflection, and improving touch sensitivity. It also contributes to structural stability, especially under high-temperature cycling common in automotive environments.
Chemical tempering strengthens the glass surface against scratches and mechanical stress. Long-lasting UV resistance prevents discoloration and peeling in outdoor or high-exposure environments.
An extended antibacterial coating further increases reliability for shared industrial and automotive interfaces, safeguarding hygiene in public-use scenarios.
Cover glass with these specifications is widely adopted in:
In-vehicle smart systems: Navigation, infotainment, and HUDs.
Center consoles: Interactive control panels requiring robust glass.
EV charging stations: Outdoor terminals demanding high UV resistance.
Industrial control equipment: Human-machine interfaces with strong durability requirements.
