1.G+G capacitive touch technology G+G means sensor glass + tempered glass, referred to as G+G, that is, the surface of the touch screen that our fingers touch is a layer of tempered glass. The entire screen is a flat mirror. The inspection method is to press the edge of the screen with your finger. It is very hard and will not dent. Huawei, Apple, Samsung mobile phones and current tablets all use G+G capacitive screens, which are hard and wear-resistant, require high technology and high cost!

2. G+P capacitive touch technology G+P means sensor glass + PET plastic sheet, referred to as G+P, that is, the surface of the touch screen that our fingers touch is a layer of PET plastic sheet. Most screens are concave screens, but there are also flat mirrors. The inspection method is the same as G+G. Pressing the edge of the screen with your finger is soft and will dent. This is because the PET plastic sheet is not as hard as the G+G tempered glass capacitive screen. Most of the capacitive screens on the market that use G+P material are some low-end knockoff mobile phones and most domestic capacitive screen tablets. When the capacitive screen of G+P material slides, you can clearly see the depression or even water ripples. It is easy to scratch and not wear-resistant. The process is simple and the cost is low!

3. G+F capacitive touch technology The meaning of G+F is the touch screen of sensor film FILM material + surface tempered glass. In fact, this technology is not called capacitive technology. Later it was renamed nano touch technology. In the early stage, some second-rate manufacturers used it to deceive users in order to reduce costs. It is also called gold wire grid touch because this touch display screen has a layer of something similar to a grid on the screen, and the experience effect is poor. The current development is also OK. Most of them are used in large-sized educational all-in-one machines, conference all-in-one machines and outdoor all-in-one machines. This just fills the size that G+G technology cannot take into account, and can also reduce a lot of costs. At present, commercial capacitive display all-in-one machines mainly use G+G capacitive technology. The other two are not commonly used, especially those 65 inches and below must use G+G, so that the experience effect is excellent, just like the experience of our mobile phones. For those above 65 inches, such as 75 inches, 86 inches, 98 inches, and 100 inches, because G+G technology has not yet been popularized and the cost is extremely high, it can only be replaced by G+F now. However, sooner or later it will be replaced by G+G. This is the touch technology analysis of capacitive touch all-in-one machines.
