When suppliers ask if you need G+G, G+F, or G+FF technology, you may not fully understand the differences or know which one fits your needs. Here’s a brief overview to help you decide.
Basics of G+G, G+F, and G+FF
LCD screens consist of three parts: the cover glass (CG), the touch panel (TP), and the display screen. G+G, G+F, and G+FF technologies are applied at the TP layer.
- G+G (Glass-Glass): CG + ITO Glass
- G+F (Glass-Film): CG + ITO Film
- G+FF (Glass-Film-Film): CG + ITO Film + ITO Film
1. GG Technology (Glass-Glass)
G+G technology uses two glass layers: a protective cover glass on top and a sensor glass underneath.
- Durability: Its double-glass structure provides strong resistance to scratches and impacts, making it ideal for rugged use.
- Touch Sensitivity: The sensor glass offers high precision and responsiveness, perfect for premium devices.
- Visual Clarity: Glass layers deliver sharp visuals and enhanced brightness.
However, its heavier weight and higher fragility make it less suited for devices requiring special shapes.
2. GF Technology (Glass-Film)
G+F technology combines a glass cover with a flexible plastic film as the sensor layer.
- Lightweight: It reduces weight compared to G+G, making it ideal for portable devices.
- Cost-Effective: The use of film lowers production costs, balancing performance and affordability.
- Flexibility: The plastic film supports curved designs, expanding its application range.
While more flexible, G+F touchscreens are less durable, less scratch-resistant, and typically limited to single-touch functionality. and its anti-interference ability is not good. Moreover, it is mainly single point and does not support multi-touch.
3. GFF Technology (Glass-Film-Film)
G+FF technology adds an extra film layer below the sensor film.
- Precision: Dual-film layers ensure smooth touch input and accurate stylus handwriting.
- Multi-Touch Support: This technology handles complex gestures and interactions effortlessly.
- Customizable Shapes: Flexible film layers accommodate unique screen shapes for specialized designs.
- Anti-Interference: Strong resistance to electromagnetic interference makes it reliable in industrial settings.
However, G+FF may have slightly reduced optical clarity and lower durability compared to G+G.
