Capacitive touch screen is widely used in all walks of life because of its robustness, fast response, space saving and convenient communication. Although they are all capacitive screens, the touch experience is different. This is due to the use of capacitive screen materials. The capacitive screen is mainly composed of the lower sensor glass layer and the upper cover. There are two kinds of capacitive screens on the market: one is inductive glass+tempered glass cover plate structure, referred to as G+G capacitive screen for short; The second is the sensor glass+＋PET plastic cover structure, referred to as G+P capacitive screen. Here's the difference between G+G and G+P capacitive screen!　　　　 

　　G+p capacitive screen　　 

　　G+P means sensor glass＋PET plastic sheet, abbreviated as G+P, that is, the surface of the touch screen touched by our fingers is a layer of PET plastic sheet. Most screens are concave, but there are also flat mirrors. Check the method with g+g .. Press the edge of the screen with your finger. It is soft and dented. This is because PET plastic film is not as good as tempered glass capacitor made of G+G. The screen hardness is high, and most capacitive screens made of G+P material on the market are some low-end cottage phones and most domestic capacitive screen tablets. G+P capacitive screen can clearly see dents and even water ripples when sliding, which is easy to scratch but not wear-resistant, with simple process and low cost!

　　G+g capacitive screen　 

　　 G+G means sensor glass+tempered glass, abbreviated as G+G, that is, the surface of capacitive touch screen touched by our fingers is a layer of tempered glass. The whole screen is a pure flat mirror. Check by pressing the edge of the screen with your finger. The edge of the screen is hard and won't sag. Like Apple, Samsung's high-end mobile phones and Taipower's Fengrui series flat panels, they all adopt G+G capacitive screens, which are hard and durable. Grinding process requires high requirements and high cost!

　　The difference between G+G and G+P　 

　　 1：G＋G+G tempered glass capacitive screen is hard and not easy to scratch, while G+P plastic film capacitive touch screen is easy to scratch, and the screen will be scratched after being used for a period of time.　　 

　　 2：G＋G+G tempered glass capacitive screen is corrosion-resistant, and G+P plastic capacitive screen will become hard and discolored under the action of acid and alkali oil, and obvious "white spots" and "aerosol" will appear, which will reduce the picture definition!

　　 3: The light transmittance of G+G tempered glass capacitive screen exceeds 91, and that of G+P plastic sheet is lower than 83. The glass is clearer and the PET is blurred, which is a common "oil screen" before. After a long time, the PET will become more and more blurred!
