GFF Capacitance Touch Screen

What is G+F+F Projected Capacitive Touch Screen?

The G+F+F structure is a relatively new structure used for projected capacitive touch screens that has gained attention for its high reliability. It includes cover glass, film sensor, and another film sensor that are used to achieve the touch function.

Dr Pan: Welcome to DISPLAY Museum. I am Dr Pan, the curator of Museum.

Greg: Hello, Dr Pan. I am Greg. There are so many structures for projected capacitive touch screen. May I ask what G+F+F structure is?

Dr Pan:  Hello, Greg. G+F+F means cover glass+film sensor+film sensor. It is going to need two-layer film sensors to achieve the touch function. Let us look at the structure “Two-sheet two-ITO laminated structure” . From top to bottom, Cover glass, OCA1, ITO1, Film1, OCA2, ITO2 and Film2.

Advantage:highly accurate, multi-touch, good at hand writing, replaceable cover glass, high strength, high reliability, strong anti-ESD, strong anti-interfered and suitable for all sizes.

Disadvantage:lower transmission and more expensive.

Greg: Dr Pan, I can see that G+F+F structure is very reliable, but we don’t see it on the market very often, do we? 

Yes, it can’t be widely used because of lower transmission only 80% and high price. But it is still used for high-end equipments because of high reliability.

Greg: Thank you, Dr Pan. Now I got it.

Dr Pan: Welcome to contact us if you have any question.

Advantages of G+F+F Projected Capacitive Touch Screens

One of the key advantages of capacitive touch screens is their high accuracy, which is achieved through the use of the G+F+F structure. This structure allows for multi-touch capabilities and excellent handwriting recognition, making it ideal for applications that require precise input. Additionally, the cover glass is replaceable, which makes it easier to maintain the touch screen over time. Capacitive touch screens also offer high strength and reliability, with resistance to scratches, cracks, and other forms of damage.

In addition to its high reliability, the G+F+F structure also offers other benefits for projected capacitive touch screens. For example, the structure allows for more precise input and better accuracy, making it ideal for applications that require highly accurate touch input, such as medical equipment and industrial machinery. Additionally, the G+F+F structure enables multi-touch capabilities, which is essential for many modern touch screen applications.

Capacitive touch screens are also highly durable and resistant to scratches and other forms of damage, which makes them ideal for use in harsh environments. Furthermore, capacitive touch screens offer strong anti-ESD and anti-interference capabilities, which ensure consistent performance even in electrically noisy environments.

Looking ahead, it is likely that new developments will emerge that will further enhance the performance of projected capacitive touch screens. As the technology continues to advance, it is possible that new structures will be developed that will address the limitations of the G+F+F structure and enable even greater precision and accuracy in touch screen applications.

Limitations of Capacitive Touch Screens

Despite their many advantages, capacitive touch screens have some limitations that affect their use in the market. One of these limitations is their lower transmission rate, which can affect the clarity of the image displayed on the screen. Additionally, capacitive touch screens are generally more expensive than other touch screen structures, which can limit their adoption in some applications.

G+F+F Structure in the Market

The G+F+F structure, specifically, is not commonly used in the market due to its limitations. It has a lower transmission rate of only 80% and higher costs than other touch screen structures. However, it is still used for high-end equipment due to its high reliability. This structure is especially useful for applications that require stable performance and precise input, such as medical equipment, industrial machinery, and aerospace technology.

The Future of Capacitive Touch Screens

As technology continues to advance, it is likely that new developments will emerge that will further enhance the performance of projected capacitive touch screens. While the G+F+F structure may not be widely used in the market today, it represents an important step forward in the development of touch screen technology. As new applications emerge, it is possible that the G+F+F structure will become more widely adopted, and that other new structures will be developed to meet the evolving needs of the market.
