Does anyone often hear suppliers asking, do you need G+G, G+F or G+FF, but we may not know exactly what we want, or we don’t know the difference between them at all? Let’s briefly introduce them now.
First of all, let’s review some basics about LCD, we know that LCD screen consists of three parts: we know that the LCD screen comprises three parts: cover glass (CG), TP, and screen. The technology of GG, GF, GFF, is carried out at the TP layer.
GG: CG+ITO GLASS
GF: CG+ITO FILM
GFF:CG+ITO FILM+ITO FILM
1. GG Technology (Glass-Glass)
GG technology refers to touchscreens that are constructed using two layers of glass. The top layer is the protective cover glass that you interact with, while the second layer is the sensor glass that detects touch inputs.
- Durability: GG technology is known for its robustness and durability. The double glass layers provide strong protection against scratches and impacts, making it ideal for devices that are frequently exposed to rough conditions.
- Touch Sensitivity: The sensor layer in GG touchscreens is highly responsive, allowing for precise touch input. This makes GG technology a popular choice for high-end smartphones and tablets where touch accuracy is paramount.
- Visual Clarity: Since both layers are glass, GG touchscreens typically offer excellent visual clarity and brightness, enhancing the user experience with crisp and vibrant displays.
However, dual glass layers also make GG touchscreen slightly heavier than other technologies, more susceptible to impact and damage, and is not suitable for situations where special shapes (such as cat-ear type) are required.
2. GF Technology (Glass-Film)
GF technology utilizes a combination of glass and a plastic film. The top layer is still glass, providing a durable surface for interaction, while the sensor layer is made from a flexible plastic film.
- Lightweight: GF technology is generally lighter than GG due to the use of plastic film instead of a second glass layer. This makes it a popular choice for devices where weight and portability are critical factors.
- Cost-Effective: The use of film instead of glass can reduce production costs, making GF touchscreens a more affordable option. This technology is often found in mid-range devices that balance performance with cost.
- Flexibility: The plastic film used in GF technology allows for some flexibility, which can be advantageous in certain applications, such as curved or flexible screens.
However, plastic film may not be as durable and scratch-resistant as glass, and long-term use may cause the GF touch screen to wear and tear more easily. In addition, due to different material properties, its visual clarity may be slightly lower than that of the GG touch screen 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)
GFF technology builds on the GF structure by adding an additional layer of film beneath the initial plastic film. The top layer remains glass, while the two underlying film layers handle the touch sensing.
- High Precision and Handwriting Effect: The dual film sensor layers in GFF technology enable high precision touch detection. This makes GFF touchscreens highly responsive and ideal for applications requiring accurate input, such as stylus use. The technology ensures a smooth and natural handwriting experience, which is particularly beneficial for note-taking and drawing.
- Support for Multi-Touch: GFF technology is designed to support multi-touch functionality, allowing for complex gestures and interactions on the touchscreen. This is essential for modern devices that rely on multi-touch inputs for a wide range of applications.
- Flexibility in Design: One of the key advantages of GFF technology is its ability to accommodate special shapes and designs. The film layers can be customized more easily than glass, making it possible to create touchscreens with unique shapes and forms. This flexibility is particularly useful for devices that require non-standard screen designs.
- Strong Anti-Interference Ability: The dual film layers provide strong anti-interference capabilities, ensuring stable and reliable performance even in environments with significant electromagnetic interference. This makes GFF touchscreens suitable for industrial applications or use in environments with high levels of electronic noise.
- Cost-Effective Production: GFF technology benefits from lower mold opening costs and shorter production times compared to other touchscreen technologies. This cost-effectiveness makes it an attractive option for manufacturers looking to produce high-quality touchscreens without incurring high production expenses.
However, like GF technology, GFF touchscreens may not be as durable and scratch resistant as GG touchscreens, their light transmittance is relatively low, and the additional film layer can slightly affect the optical clarity of the display.
