1.
High hardness and scratch resistance: The surface uses chemically strengthened tempered glass with a hardness of 7–9H, significantly higher than the 3–4H level of G+F or G+P structures. It can effectively resist scratches from daily objects such as keys, sand, and tools, leaving almost no visible marks, and supports long-term use without the need for an additional protective film.
2.
Impact and bending resistance: The dual-glass structure provides high rigidity and strong flexural strength, enabling it to pass 1-meter drop and heavy impact tests. Compared with film-based structures, it offers better vibration resistance and is less prone to deformation, making it well-suited for automotive systems, industrial control equipment, and outdoor self-service terminals.
3.
Wide-temperature stability and aging resistance: Glass has a very low thermal expansion coefficient, ensuring minimal touch drift (±0.3 mm) across a wide operating temperature range of -40°C to 85°C. Unlike PET film, it does not warp at high temperatures or become brittle at low temperatures. It is also UV-resistant, anti-yellowing, and resistant to salt spray, acids, and alkalis, ensuring long-term outdoor use without aging or color fading.
4.
Long lifespan and high reliability: The touch system supports over 10 million touch cycles, with no issues such as film fatigue, delamination, or adhesive failure. It is well-suited for 24/7 continuous operation in mission-critical devices.
5.High transmittance and low reflection: Light transmittance reaches 90%–92% (compared to only 84%–86% for G+F structures). Full lamination eliminates the air gap, reducing reflectance to below 1.2%. This significantly improves visibility under strong ambient light, delivering a clearer image with more accurate colors and no hazy or fog-like appearance.
6.Supports advanced surface treatments: can be equipped with AG anti-glare, AR anti-reflection, and AF anti-fingerprint / anti-oil coatings. It maintains clear visibility even under strong outdoor sunlight, while providing a smooth, non-sticky touch experience.
7.Responsive and accurate touch performance: The glass substrate provides uniform signal distribution and a high signal-to-noise ratio, enabling precise multi-touch (10-point and above) and accurate gesture recognition, with reporting error below 0.5%. It supports operation with thin gloves, wet hands, and oily hands, delivering better performance than film-based structures.
8.Smooth sliding experience: The glass surface has a low coefficient of friction, enabling effortless, low-resistance, and lag-free sliding. It delivers a significantly smoother and more fluid operation compared to PET/GFF film-based solutions.
