5 Advantages Of G+G And G+P capacitance touch screen

5 Advantages Of G+G And G+P capacitance touch screen - Table of contents:

We use the touch screen every day, but a lot of people do not even know how the touch screen is composed.

Now we generally use capacitance touch screen, and this type of touch screen is generally made of tempered glass, sensor glass, PC materials, plastic materials and other components.

Mainly divided into G + G, G + F, P + G and other types.

What Does Touch Screen Structure G+G, G+P, G+F Mean?

G+G means: surface tempered glass + sensor glass.

G+P means: surface tempered glass + PC material touch screen.

G+F means: surface tempered glass + thin FILM material touch screen.

Capacitance touch screen:

The capacitance touch screen is mainly composed of two parts, the lower sensor glass layer and the upper cover. There are two types of capacitive touch screens on the market.

One is the sensor glass + tempered glass cover structure, referred to as G+ G capacitive screen.The other one is the sensor glass + PET plastic cover structure, referred to as G+P capacitive touch screen.

The capacitive touch screens of Apple iPhone, iPad and some high-end Android tablets are of G+G structure. The bottom layer is touch-sensitive glass, and the upper cover is tempered glass. Many low-end capacitive touchscreen tablets currently on the market use G+P this low-cost capacitive touchscreen.

What Is The Difference Between The G+G And G+P?

Since first applied the capacitive touch screen to the iPhone. The capacitive touch screen has become the standard configuration of high-end mobile phones, tablets and other smart portable devices.

The capacitive touch screen does not require a special pen. We can very easily and sensitively use our finger to operate directly. It is very convenient.

Capacitive touch screens quickly eliminated resistive touch screens. The dispute between G+G and G+P has resurfaced on the capacitive touch screen.

The Advantages Of G+G And G+P capacitative touch screen:

1) Hard And Wear-resistant

The surface cover of the G+G capacitative touch screen is tempered glass. Its surface is very hard, the hardness can reach 6H- 7H. As long as you don’t need to grind super-hard objects. Such as quartz, emery paper. Generally, you don’t have to worry about scratches.

The disadvantage is that the processing technology is difficult and the cost is high.

However, the surface of the G+P capacitive screen is PET plastic. The hardness is usually only 2~3H, which is quite soft.

Moreover,it is very easy to produce scratches in daily use.So you can add a film and carefully protect it. Its advantages are The process is simple and the cost is low.

2) Corrosion Resistance

The surface of the G+P capacitative touch screen is plastic. So it is easy to harden, become brittle, and change color under the action of acid, alkali, oily substances and sunlight. Therefore, you must use it carefully to avoid contact with these substances. If improper use, it will produce aerosol and leukoplakia.

The tempered glass surface of the G+G capacitative touch screen is very resistant to corrosion. It is not afraid of similar substances at all. And strong acid and alkali are not good. You can use it with confidence and boldness anywhere, especially when you are eating and operating. it is inevitable that your fingers Will not be stained with grease.

The corrosion resistance of the G+G capacitive screen is extremely obvious.

3) High Light Transmittance

We not only use the capacitance touch screen for operation, but more importantly, for viewing and appreciating the screen content.

The light transmittance of the G+G glass capacitance touch screen is as high as 91%. It has little effect on the screen picture. While the G+P PET cover is transparent. The light rate is only 83%, the light loss is serious. The picture is inevitably low and dim.

However, the light transmittance of the PET cover will gradually decrease over time. It is also a fatal flaw of the G+P capacitance touch screen.

4) The Control Feels Smooth

The glass screen of G+G is very smooth. And the touch of fingers is like clouds and water. Moreover, the control feels very smooth. While G+P’s PET plastic is a polymer material with great surface damping force. So the sliding feel is jerky and not smooth. It is very influential operating experience.

5) High Reliability

The cover plate of G+G capacitive screen and sensor glass are glued using advanced optical glue and vacuumed. It has a very high service life and adhesion.

G+P capacitive screen uses PET’s own chemical glue for bonding . 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 thermal expansion .

And contraction of the G+P capacitive screen sensor glass and the PET plastic cover is huge. However, at high or low temperatures, the G+P capacitive screen will be prone to the difference in the expansion coefficient. And cracked, thus scrapped!

Because capacitive touch screen hard&wear-resistant, corrosion-resistant, high light transmittance, smooth handling feel, high reliability, and the mahcine look more thinner and lighter.
