Touch screen G + G, G + P, G + F these what mean?
This is the first letter mobile phone surface structure classification, material (also known as the upper level), the material of the second letter is touch screen (also called
Below), both joint together,
G + G is said: the surface of toughened GLASS + GLASS material of GLASS touch screen
G + P is said: surface of toughened glass + PC material of touch screen
Toughened glass + G + F is said: surface FILM FILM material of touch screen
We first to get to know: a sensor at the bottom of the capacitance screen mainly have glass layer and the upper cover plate of two parts, now the city
There are two kinds of structure of capacitive touch: one kind is sensor + toughened glass cover plate structure, referred to as "G + G capacitance screen; The second is
Sensor glass + PET plastic cover plate structure, referred to as "G + P two capacitance screen, apple iPhone, tablet and some high-end android
Flat capacitance screen is G + G structure, the bottom is touch glass, the upper cover plate is toughened glass, and currently on the market do not
Less low capacitance screen plate is adopted G + P this low-cost capacitive screen, so what is the difference between the two?
Since Steve apply capacitive touch screen for the first time to the Iphone, capacitive touch screen is a high-end mobile phone, tablet, etc.
Standard configuration intelligent portable devices, capacitive touch screen without special pen, could easily be sensitive with finger directly interface,
Very convenient to use and capacitive touch screen is also quickly eliminated resistive touchscreen, G + G, G + P battle again in capacitive touch
On the screen surface,
? G + G and G + P and the advantages and disadvantages of the capacitance screen
G + G is the advantage of capacitive touch is hard wear-resisting, corrosion resistance, high light transmittance, manipulation of the feel is smooth, high reliability, and G + P
RongBing has the advantage of low cost, simple process, but the downside is very outstanding, not wear-resisting, corrosion resistance, light transmittance is poor, fuck
Control handle viscous, poor reliability, almost with G + G capacitance screen exactly the opposite, let us detailed understanding of G + G and G + P electric
RongBing advantage contrast:
1, G + G capacitive touch advantage one: hard wear-resisting
G + G capacitive touch the surface of the cover plate is toughened glass, its surface is very hard, hardness can reach more than 8 h, as long as you don't need to
Quartz, hard objects such as emery paper to grind, generally without sticker also don't have to worry about will produce scratches, the downside is processing work
Art is difficult, high cost; And G + P capacitance screen surface for PET plastic, hardness is usually only 2 ~ 3 h, very soft, daily make
Use very prone to scratches, must be sticker and careful protection, the advantages of simple technology, low cost,
2, G + G capacitance screen edge 2: corrosion
G + P capacitance screen surface is plastic, in acid, alkali, oily substances and under the action of sunlight to harden and become fragile, discoloration,
So must be careful to use, avoid contact with this kind of material, if use undeserved can produce aerosol and white spot, very hard to serve,
And G + G capacitance screen of toughened glass surface is very resistant to corrosion, not afraid of similar material, acid alkali can do,
Can rest assured the bold use anywhere, especially if you eat, when operating, hard to avoid the fingers will not stain the
Grease, G + G capacitance screen corrosion advantage is very obvious,
3, the capacitance screen the advantage of 3 G + G: high light transmittance
Capacitance screen is not only used to operate, more important is to watch the appreciate the content of the screen, G + G glass capacitance screen high light transmittance
Was 91%, and the impact on the screen is not big, and G + P PET cover plate light transmittance is only 83%, the light loss is serious, the picture
Unavoidably deep dark, and with the passage of time, PET cover transmittance will reduce gradually, it is also a G + P capacitance screen
A fatal weakness,
4 G + G four: the advantage of the capacitive touch control feel smooth
G + G glass screen is very smooth, fingers delimit the past such as flowing, manipulation of the handle is very smooth; And G + P PET plastic
Is a kind of polymer material, the surface damping force is very big, feel the sliding crude, not smooth, very affect operating experience,
5, the advantage of G + G capacitance screen 5: high reliability
G + G capacitance screen cover board and sensor glass glue, USES the advanced optical glue stick merge into a vacuum, the service life of the
And bonding degree are very high; G + P use the PET with chemical glue joint capacitance screen, process is very simple, but the bonding reliability
Is not high, there is one important point: G + P capacitive touch sensors with toughened glass, PET plastic cover the expansion of the heat bilges cold shrink
Coefficient difference is huge, at high temperature or low temperature, G + P capacitance screen may break easily because of the difference in expansion coefficient, thus to
Waste! So the repair rate G + P capacitance screen is much better than the G + G capacitance screen,
