Physical Structure of Capacitive Touchscreen
There are two types of capacitive touchscreen structures: a double-layer structure with X/Y electrodes on each of two pieces of glass or film, and a single-layer structure with X/Y electrodes (ITO film) on one or both sides of a single piece of glass or film. DMC mainly adopts the double-layer structure from the viewpoint of ease of handling a wide variety of products in small quantities.
GG: Glass/Glass Structure
The glass is laminated with an X-electrode on one side and a Y-electrode on the other side, with the electrodes facing each other.
GFF: CoverGlass + Film/Film Structure
One side of the film is coated with X-electrode, the other side with Y-electrode, and each electrode is laminated to the touch surface. Compared to the glass/glass structure, it has the advantage of being lighter and thinner, making it ideal for applications such as handheld devices that are carried around. If acrylic or tempered glass is used for the cover lens, a touchscreen that is resistant to breakage can be realized.
