This is the structural classification, the first letter mobile phone surface material (also known as the upper layer), the second letter is the touch screen material (also known as the lower layer), when the two are attached together,it is as follows;
G+G is surface tempered glass + glass GLASS touch screen.
G+P is a touch screen with a surface tempered glass + PC material.
G+F is a touch screen with surface tempered glass + film FILM material.
The capacitive screen is mainly composed of a lower sensor glass layer and an upper cover. Now there are two types of capacitive screens on the market.
The first one is sensor glass + tempered glass cover structure, referred to as G+G capacitive screen.
The second one is sensor glass + PET plastic cover structure, referred to as G + P capacitive screen.
The advantages of G+G capacitive screen are hard wear resistance, corrosion resistance, high light transmittance, smooth handling and high reliability.
The advantages of G+P capacitive screen are low cost and simple process, but the disadvantages are also apparent. It is not wear-resistant, corrosion-resistant, and has poor transmittance.
