As early as the iPhone5 era, tempered glass film began to hot up, on some of the characteristics of tempered glass film, please see the contact before the release of the "mobile phone glass film You do not know some things."
At that time the mobile phone is basically still normal flat screen, of course, because of Apple's Halo shine, many screen very character of the mobile phone was forgotten, such as NokiaN9, Lumia800, GalaxyS3, etc. At that time, the so-called 2.5D screen has not really let people realize its charm, until the September of this year, IPHONE6/6 plus turned out, so that the 2.5D screen back to our sight, and the problem of the arc-screen foil film is once again let many film manufacturers hurt their brains ...
First, let's figure out what the 2.5D screen is.
2.5D screen This is a general term in the industry, refers to the center of the glass has a plane area, surrounding the arc surface over, that is, on the basis of flat glass on the edge of the arc processing.
Advantages of 2.5D Screens
The main function of the 2.5D screen is to enhance the overall visual effect of the screen and the fuselage while elevating the feel. On the phone screen surface covered with a 2.5D of arc glass, can make the surface appearance of mobile phone as a surplus and not overflow water droplets, more visual tension. This adds a lot to the visual expressiveness of the mobile screen.
And in the actual use, the single hand holding and thumb to slide the operation of the screen is very high probability, and when the user adopts this posture, the thumb slide is not a plane but an arc, so the 2.5D screen of the arc surface modeling more in line with the principles of human engineering.
The surrounding Arc surface transition eliminates the edge of the blunt edges and corners, greatly enhance the sliding screen feel. This is also a number of manufacturers to increase the product experience and the main reason to adopt 2.5D screen
Disadvantages of the 2.5D screen
2.5D screens do have a lot of advantages over traditional screens, but for most users who like to film on a mobile screen, the 2.5D screen is a nightmare. Because for the user who cherishes the mobile phone, if the screen glass does not resist scratch, then the curved screen is more easily scratched and broken than the 2D screen.
Since the 2.5D screen also has the problem of easy to damage, then the film is essential, but in the traditional flat screen hand film on the iPhone6 so large arc surface on the film, it is necessary to make some compromises!
Arc Surface Screen Film solution:
This is the most common and easiest way to achieve, the size of the film only to do the screen plane part so large, let the arc edge of the part exposed, so that both can be very easy to paste up, but also to protect most of the screen area, so the way the film is in the first time by the vast number of film manufacturers launched.
2, flat full screen glass cover
In fact, this method is in the traditional internal shrinkage film based on the glass area to enlarge a circle, so as to ensure that the glass film can basically cover iPhone6 all the screen, However, due to the IPhone6 2.5D arc screen, and the glass film is still flat, so the edge is not fully fit, in the transparent glass film, will appear to be unable to fit the four sides are white bubbles, very very ugly! So manufacturers are using the glass film around the printing or electroplating color to headmistress, So there are a variety of color full screen laminating glass film.
What is the difference between printing and electroplating on glass?
Generally to the glass film electroplating is the use of vacuum electroplating, the use of vacuum state, the more lively aluminum atoms, coupled with the principle of electrostatic absorption of the opposite sex, the aluminum atoms attached to the surface of the glass, thus forming color. Electroplating can make the surface of the color to be very thin, the thickness can be almost negligible (the latter will be mentioned why this part of the thickness), but the shortcomings are also obvious, after electroplating with
Color glass transmittance is very poor, affixed to this kind of glass film mobile phone in the strong light environment is almost invisible screen content, the visual experience is very poor still hurt eyes.
And to make the glass film printing is in the glass around like the cell phone panel itself as the proportion of the printing color, only the middle of the display area is transparent, so that the effect on the phone itself and the effect of the Panel, not only to ensure that the display area of light transmittance to the glass itself transmittance 95%, is to maintain the glass film as the original machine in general original, but the problem is also obvious, because the printing is a certain thickness, although the naked eye observation is not very obvious, but the glass film as an optical product, the overall need to maintain a very good flatness, and the thickness of the surrounding printing and the middle of the printed part will form a step , so when with the mobile phone, because the adhesive glue because the printing steps are not smooth, this part of the stage will be in the display area of four weeks to form a circle of white offset printing, ordinary users may feel already very ok, but Virgo's machine friends may be going crazy.
3, the glass film hot-pressing forming arc surface
The transparent glass substrate made as large as the IPhone6 screen, and the use of hot embossing technology will be surrounded by the iPhone6 of the radian shape, so that the glass film and IPhone6 close contact with the perfect fit ... That's genius, perfect!.
The ideal is plump, but the reality is bone feeling, such a practice has the following several problems:
After the glass film hot-pressing, the adhesion of the adhesive is difficult, it is difficult to perfect the adhesive adhesive on the curved glass, does not have the characteristics of mass production;
But the apple is not a god, IPhone6. The Arc-faced glass panel is also provided by several different suppliers, each of which has a different panel for each batch. The biggest tolerance even up to 0.3mm, imagine if the radian of the glass film to perfect match IPhone6 arc edge, that is how difficult to control one thing.
First of all, not to say how much the glass film hot embossing costs, glue technology is difficult to match the arc surface glass, Apple's screen tolerance can kill a group of siege lions, so that this method is completely without the possibility of mass production, can only stay in the laboratory stage to show off a little.
Speaking of this, everyone is going to be crazy, my iPhone6 screen in the end how to protect?!
4, the fluidity of the suspension filling technology
This method is improved on the basis of the 2nd method (Glass printing process), solve the full screen of glass film affixed to the mobile phone after the display area four weeks of white-edge problems, more because of the fluidity of the suspended filler layer can better fit the phone's arc surface, forming the arc surface buffer layer, so as to better protect the phone screen, And with the glass film 2.5D arc edge Grinding, feel and visual effects are comparable to IPhone6 original machine effect!
Implementation principle:
Using a removable suspension filling layer, first the glass film itself caused by the level of the steps to fill the surface, and then affixed to the surface of the iPhone6 screen, the suspension is based on the surface of the mobile phone to fill in the arc of the free flow of parts due to the screen and can not contact the glass film, thus forming a perfect fitting effect.
Thus far, the most perfect IPHONE6/6 plus full screen laminated glass film was born, although the flow of floating technology has not been fully promoted, the cost is relatively high, but throughout the current film technology standards, this is the best solution, the market and the pursuit of consumers is the best verification!
Summary: If you are still in the tangle IPhone6 to paste which kind of film, after reading this article, I believe you have made your own choice, the traditional shrink glass film will be a simple, quick and affordable choice, but if you have higher vision and feel, do not hesitate to choose the 4th kind, perfect!
Well, said so much, the question is: foil technology which good?
