Capacitive touch screens are widely used in all walks of life because of their durability, fast response speed, space saving, and easy communication. Although they are all capacitive screens, the touch experience effect is different. This is caused by the use of capacitive screen materials. The capacitive screen is mainly composed of the lower sensor glass layer and the upper cover plate. There are two types of capacitive screens in the market: one is the sensor glass + tempered glass cover plate structure, referred to as G+G capacitive screen; the second is the sensor glass + PET plastic cover plate structure, referred to as G+P capacitive screen. The following introduces the difference between G+G and G+P capacitive screens!
1. G+P capacitive screen:
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 of the screens are concave, but there are also pure flat mirrors. The inspection method is the same as that of 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 tempered glass capacitive screen made of G+G. 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 sliding the capacitive screen made of G+P material, you can clearly see the dents and even water ripples. It is easy to scratch and not wear-resistant. The process is simple and the cost is low!
2. G+G capacitive screen:
G+G means sensor glass + tempered glass, abbreviated as G+G, which means that the surface of the capacitive touch screen that our fingers touch is a layer of tempered glass. The entire screen is a pure flat mirror. The inspection method is to press the edge of the screen with your finger. It is very hard and will not dent. Apple, Samsung’s high-end mobile phones and Teclast’s sharp series tablets all use G+G capacitive screens, which are hard and wear-resistant, require high technology and high cost!
The difference between G+G and G+P
1: G+G tempered glass capacitive screen is hard and not easy to scratch, while G+P plastic sheet capacitive touch screen is easy to scratch, and scratches will appear on the screen after a period of use.
2: G+G tempered glass capacitive screen is corrosion-resistant, G+P plastic sheet
The capacitive screen will harden and discolor under the action of acid, alkali and oil, and there will be obvious “white spots” and “aerosol”, and the screen clarity will be reduced!
3: The transmittance of G+G tempered glass capacitive screen exceeds 91, and the transmittance of G+P plastic sheet is less than 83. Glass is clearer, PET is blurry, which is the common “oil screen” in the past, and PET will become blurrier over time!
