Fill out my online form.
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 structure is?
Dr Pan: Hello, Greg. G+F means cover glass+film sensor.
Dr Pan: It is going to need single-layer film sensor to achieve the touch function.
Dr Pan: Let us look at the structure “One-sheet one-ITO piled-up structure”.
Dr Pan: From top to bottom, Cover glass, OCA, ITO and Film.
Dr Pan: Advantage: low R&D, low cost, thin, short delivery time, replaceable cover glass, high transmission, high strength, high reliability.
Dr Pan: Disadvantage: single touch point, low anti-ESD, low anti-interference, only suitable for the sizes less than 6 inch.
Greg: Dr Pan, we can barely see G+F structure capacitive touch screen on the market, why?
Dr Pan: It can’t be widely used because it can’t support multi-touch
Dr Pan: and it is only suitable for small sizes.
Dr Pan: But it is still used for single-touch-point equipments because of relatively low cost.
Greg: Thank you, Dr Pan. Now I got it.
Dr Pan: Welcome to contact us if you have any question.
