Advantages and disadvantages of G+G and G+P capacitive screens

What is G+G and G+P Structure?

G+G Structure: surface tempered GLASS + glass touch screen material

G+F Structure: touch screen with tempered glass surface and film material

1.G+G capacitive screen advantage: hard and wear-resistant

G+G capacitive screen surface cover is tempered glass, its surface is very hard, hardness can reach more than 8H, as long as you do not use quartz, emery paper and other super-hard objects to grind, generally do not need to film and do not worry about scratches, the disadvantage is that the processing process is difficult, high cost;

The surface of the G+P capacitive screen is PET plastic, the hardness is usually only 2~3H, quite soft, daily use is very easy to produce scratches, must be coated and carefully protected, its advantages are simple process and low cost.

2. G+G capacitive screen advantage: corrosion resistance

The surface of the G+P capacitive screen is plastic, which is easy to harden, become brittle and discolor under the action of acid, alkali, oily substances and sunlight, so it must be used carefully to avoid contact with such substances, if used improperly, it will produce aerosol and white spots, which is very difficult to serve.

The toughened glass surface of G+G capacitive screen is very corrosion resistant, is not afraid of similar substances, strong acids and alkali can not be helpless, you can be assured of bold use anywhere, especially when you eat, while operating, it is inevitable that the fingers will not be greasy, G+G capacitor screen corrosion resistance advantages are extremely obvious.

3. The advantage of G+G capacitive screen : high transmittance

Capacitive screen is not only used to operate, more importantly, is used to watch the content of the screen, G+G glass capacitive screen transmittance of up to 91%, has little impact on the screen, but G+P PET cover light transmittance of only 83%, light loss is serious, the picture is inevitably low and dim, and over time the PET cover light transmittance will gradually decrease. This is also a fatal drawback of G+P capacitive screens.

4.The advantage of G+G capacitive screen: smooth control

G+G's glass screen is very smooth, finger strokes like flowing water, the control feel is very smooth; The PET plastic of G+P is a kind of polymer material, the surface resistance is very large, the feel of the slide is uncomfortable, not smooth, very affecting the operating experience.

5. Advantage of G+G capacitive screen: high reliability

The adhesion of the cover plate and the sensor glass of the G+G capacitive screen uses advanced optical glue to paste and vacuum, and the service life and adhesion are very high; G+P capacitive screen uses PET chemical adhesive, the process is very simple, but the bonding reliability is not high.

There is also a very important point: the thermal expansion coefficient of the sensor tempered glass of G+P capacitive screen is very different from that of the PET plastic cover plate. At high temperature or low temperature, the G+P capacitive screen will easily crack due to the difference in the expansion coefficient, thus scrapped!
