5.5-inch G+F+F Structure Projected Capacitive Touch Panel for Smart Electronic Equipment
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.
Dr Pan: It is going to need two-layer film sensors to achieve the touch function.
Dr Pan: Let us look at the structure “Two-sheet two-ITO laminated structure”.
Dr Pan: From top to bottom, Cover glass, OCA1, ITO1, Film1, OCA2, ITO2 and Film2.
Dr Pan: 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.
Dr Pan: 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?
Dr Pan: Yes, it can’t be widely used because of lower transmission only 80% and high price.
Dr Pan: 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.
