How to correctly distinguish real 3D safety glass for iPhone from counterfeit or cheap counterparts? After reading the article, you will know the main advantages and disadvantages of rounded glasses using 3D technology. Information materials will help you to make right choice and decide on the purchase of the best protective glass for the iPhone 7/8, the characteristics of which will allow you to keep the smartphone display in factory condition.

Advantages and Disadvantages of 3D Rounded Glass on iPhone

The mobile accessory market is overflowing with protection options iPhone display... Among which the most popular are 3D glass. If we consider in detail the advantages and disadvantages of this display protection format, we can make an unambiguous conclusion about the reliability of rounded coatings.

Advantages

Full coverage of the front of the iPhone;

Modern high-precision equipment makes it possible to produce protective glasses for the iPhone, which fully correspond to the dimensions of the front of the smartphone. Such glasses are usually called 3D Glass.

Air and dust free under protective glass

In addition to the 3D rounded edge, premium manufacturers such as Benks apply an adhesive layer over the entire surface of the safety glass, which makes it possible to glue the glass without an air gap. High-quality adhesive base and comparability of the size of the protective glass with respect to iPhone cases, allows you to reduce the number of defective goods to a minimum.

• Appearance

What's the point of having a screen protector if it ruins the look of your iPhone? That's right, no. That is why you should buy glass from manufacturers who know exactly Apple's color palette and have conducted more than one tinting experiment. Make sure from reviews or reviews on forums / sites in the reliability of the product presented.

disadvantages

Quality

It's pretty easy to come across a low-quality fake 3D protective glass. Most retail stores sell safety glasses without an official manufacturer's warranty. This means only one thing: it will be very difficult to return or exchange such a product. To avoid this problem, we advise you to check with the seller for the terms of warranty service in advance.

How does poor quality affect my iPhone screen protector? Determining the quality of glass is easy, but difficult to do without installing it. After gluing, local air accumulations appear under the protective glass, which cannot be removed over time. Read online customer reviews carefully.

Strength

"9H Hardness", "Diamond strength", "Meteorite protection", what kind of marketing gimmicks you will not find in our time. Protective glass 3D form is durable if the force applied to it enters in a perpendicular plane to the base. The end face of such glass is the weakest and most fragile place. Entrust the choice of protective glass to our specialist. They will provide professional advice in the selection of the most reliable accessory.

The toughest screen protector on an iPhone we've seen in several years is Benks' King Kong (formerly Sapphire) series screen protector. The structure uses composite materials of synthetic sapphire and Gorilla glass. This gives increased strength even to the end face of the 3D safety glass with rounded edges.

Expensive does not mean high quality. The cost of 3D glass for an iPhone is several times higher than the price for a standard glass without a rounded edge. This is due to the complexity of the manufacturing process.

Case Compatibility

Not every rounded glass is capable of protecting the display together with a hardened case. In this case, you should choose a standard 2.5D tempered glass or change the case to the appropriate size. In turn, we guarantee you that Banks' protective glasses are fully compatible with the cases of this company, as well as the original silicone cases from Apple.

How to distinguish real 3D from fake or two-piece safety glass?

First of all, let's figure out what does "3D protective glass" mean?

In Russia, there is no GOST, which characterizes curved safety glasses like 3D. Based on experience, we will consider as rounded glasses using 3D technology each sample that has a non-planar facet in its composition. Many buyers might think that only the face of the glass is the rounded edge. In fact, the protective glass should completely follow the bends of the iPhone case from the side of the adhesive layer. Only in this case it will be called 3D Glass.

IPhone 3D display protection options

Cast glass with rounded edges. Type "Real 3D"

An accessory of this type is the most expensive, both in production and in retail, when compared with other options in a similar segment, which we will consider below. The high price is due to the complex manufacturing process. Real 3D - means a rounded glass of a cast structure, which is produced without variations in thickness and has a uniform shape.

The photographs show a sample of rounded glass using the Realnoe 3D technology. XPro + sample from Benks. The glass is glued to the transport plate, which prevents it from bending during transportation, and also preserves the quality of the adhesive base.

On the back of the glass, if you remove it from the plate, there is an edge-to-edge adhesive layer. You don't have to break it to test a single cast structure, as shown in our demo. It is enough to slide your finger along the opposite adhesive side. If you do not feel the difference, then the protective glass can be attributed to the "Real 3D" type.

When buying cheap glass of this shape, you may encounter a fake from an unscrupulous manufacturer. As a rule, a low price indicates a poor-quality adhesive layer. Such an accessory is quite problematic to stick to the iPhone display.

Two-piece glass with rounded silicone / metal frame

As we said earlier, one of the disadvantages of 3D glass is its high price. Not every customer can afford the expensive protection of the display from scratches and drops. If you have never dropped your iPhone on the display and handle it carefully and carefully, there is no point in buying expensive glasses like "Real 3D". Cheap two-component glasses with a silicone or metal frame come to our rescue.

What is their fundamental difference? Everything is very simple. The main composition of such an accessory is 2.5D protective glass, which is glued into a silicone or metal frame. This solution provides their low cost in exchange for loss of strength. Such glass is able to protect the display and the front of the iPhone only from scratches.

The main advantage of two-component glass is not only an attractive price, but also its thickness ~ 0.2mm. The owner of the iPhone simply will not feel the glued protective glass.

There is a significant disadvantage. Over time, the frame into which the glass is glued begins to scratch, which leads to the unsuitable appearance of the gadget. Most retail or online stores do not reflect this property in the characteristics of the product. We advise you to find out in advance detailed information about the composition of the protective glass.

Don't forget about marriage. According to sales statistics over the past few years, safety two-component safety glasses peel off much more often than glasses of the "Real 3D" type. In the case of Benks products, we provide a warranty for each protective glass that can be replaced at the discretion of the manufacturer.

conclusions

We advise you to use a protective glass that will meet your specific requirements. Based on your daily use, opt for the XPro series from Benks if your phone falls out of your hands quite often. To protect the display from scratches, use the KR + Pro two-pack hardened coatings.

Choosing the best screen protector for your iPhone doesn't require any special knowledge or experience. If you doubt your choice, contact our experts for help, who will help you resolve any issue related to the selection of premium and high-quality glass for your iPhone.

If you still have questions, ask them in the comments to this article.

The first phones all came with 2D screens. This is absolutely flat surface recessed into the metal and plastic frame of the phone body. The user could not touch its edges in any way, so the manufacturers did not think about carefully grinding the edges of such a coating. This technology it is still used in the production of some budget phone models.
The term 2.5D is a relatively new term, referring to a small bend at the edge of the display glass, also known as a contoured edge. On most phones, users may not even see the difference, but on gadgets where the glass protrudes slightly from the body, then owners will certainly appreciate the smoother edges.
But technology is not standing still, and some phone models have even more curved screens. The actual bending of the display results in a more perceptible 3D effect, but given type curved displays provide for bending and electronic parts, while 2.5D glass does not. The main manufacturer of 3D screen phones is Samsung.

The number and letter next to the glass description indicate the number of measurements:
2D - width and length. The edges of the glass are smooth and straight at the edges.
2.5D - width and length. The edges of the glass are rounded at the edges, without right angles.
3D - width, length and depth. The glass has a bend at the edges, the edges of the glass are rounded, without right angles.

Thus, we can see that 2D and 2.5D have a slight difference in the processing of glass edges, while 3D differs significantly in curved edges.

And now we offer you to visually disassemble all types of screen protection using the example of CaseBerry glasses:

Protective glass CaseBerry transparent / frosted- glass that covers only the flat surface of the phone screen. If the phone has a screen with 2.5D or 3D technology, then this glass will not cover the curves of the screen, leaving them unprotected. It is matte (slightly distorts the picture, but at the same time the image does not fade in bright or sunlight) and transparent (excellent screen brightness, no distortion, it performs protective functions perfectly and is almost invisible on the display).

Caseberry safety glass with colored / transparent frame- Full screen glass without bending, covering the entire face of the phone with a rounded 2.5D screen. It can be either completely transparent or have a colored rim. When using this glass, there may be a small gap around the edge between the screen and the glass itself, which is necessary for use. protective cover that can touch the glass. The gap is almost invisible and does not affect the visual or tactile sensations when using the phone. When using this glass on 3D screens, the top surface will be reliably protected, and the side work surface will remain less protected.

Protective glass CaseBerry full screen 3D- Full screen glass covering the entire front of the phone with a curved 3D screen. Unlike the previous bezel glass, it has a curvature that perfectly matches the curvature of the screen and provides maximum protection for the entire work surface. Like full-screen glass with a frame, it can be transparent or have a colored border.

Safety glasses 4D, 5D and 6D differ from 3D increased glass strength.

Also, not only glass, but also a protective film can become an excellent screen protector:

Plain film- like the CaseBerry protective glass, transparent / frosted covers only the flat surface of the screen. It is matte (slightly distorts the picture, but at the same time the image does not fade in bright or sunlight) and transparent (excellent screen brightness, without distortion, it performs protective functions perfectly and is almost imperceptible on the display).

Full screen film- covers the entire front surface of the screen, like the CaseBerry full-screen 3D protective glass. Suitable for phones with 2.5D and 3D screens. It happens only transparent.

It is worth considering that when using any protective glasses and films, depending on the phone model, a small gap of 1-2mm may remain between the edge of the screen and the protective glass / film. It is necessary so that when using a protective case, the case itself does not touch the protective glass, which will lead to the fact that the glass / film can "move away" from the screen.

3D, 2.5D and 2D refer to the rounding of the smartphone screen, which creates a three-dimensional effect. For example, in the series Samsung Edge The 3D display is presented in the form of smooth but deeply curved glass at the side edges of the case. Thanks to the rounding, the gadget gains modern design, expands the functionality and "animates" the image on the display, giving it realism.

Capabilities of 3D glass and screens

The side faces of a smartphone with 3D screens are illuminated even when the phone is facing down. Samsung turned this nuance in favor of the user. By setting a personal color for selected subscribers, you can determine from a distance who is calling. Taking the device in hand, from the curved area of ​​the screen, you can call up an additional menu, install applications and contacts for quick access and much more.

Another manufacturer who implemented 3D technology display to life, has become LG. The G Flex smartphone is rounded in a different way: if you turn the gadget horizontally, the display will resemble a screen in a movie theater: it is curved by a microphone and spoken speaker towards the user. This is how high level realism while watching movies and comfortable conditions are created when communicating on the phone, since the gadget more clearly follows the contours of the user's face.

The trend for 3D glass will continue for the coming years among Chinese manufacturers. Most illustrative example... While the technology isn't cheap, manufacturers understand that demand for such devices is fueled by strong marketing from A-brands.

Differences between 3D and 2.5D glasses

3D glasses in the correct sense are relevant only for gadgets with rounded screens... Chinese inventors often refer to conventional 2.5D glass as three-dimensional (3D), but in reality this is just marketing. There are also glasses marked 5D and 7D, but this is a commonplace deception.

Disadvantages of 3D glasses

Despite the impressive picture, visual beauty and pleasant tactile sensations, smartphone users also talk about the negative side of such a purchase: protecting a curved screen is much more difficult than a flat one. To minimize the risk of deforming the screen, you have to resort to using special protective 3D glasses or limit yourself to applying a protective film. The protective glasses familiar to many do not cover the bend of the screen, which means they cannot provide protection from scratches or cracks.

The displays of the first smartphones were protected by 2D glass - an ordinary rectangular piece of glass recessed into the body. The user could not touch its edges in any way without violating the integrity of the device, so the manufacturers did not think about carefully grinding the edges of such a coating.

The number and letter next to the glass description indicate the number of measurements:

• 2D - width and length;
• 3D - width, length and depth.

What does 2.5D mean in this system? Half of some dimension? No, this is a symbol for rounded edges. An example is Partner's protective glass for LG K8.

Over time, the design of smartphones changed and more attention of buyers began to be received by those models whose screen smoothly flowed into the body and the smartphone seemed smooth and monolithic. For such gadgets, 2.5D glass was created - flat glass with rounded edges.

However, designers and developers mobile devices went even further and appeared smartphones with a curved body, ranging from the concave LG G Flex, and ending, for example, Samsung Galaxy S7 edge with beveled edges. For curved smartphones, 3D glass was created that completely covers the non-planar front panel. Partner 3D protective glass for Samsung Galaxy S7 Edge is an excellent protection for the flagship device.

The main difference between 2.5D glass and 3D

The 2.5D glass is absolutely flat, and the 3D glass is curved to fit the shape of the smartphone body.

Curved 3D safety glasses are very expensive to manufacture, because the slightest mistake in creating such an accessory will lead to the fact that the glass simply does not fit on the front panel. Accordingly, such glasses are much more expensive than 2.5 accessories and require more care when gluing.

2.5D protective glasses are cheaper to manufacture and, accordingly, on sale. Thanks to the sloping edges, they visually make the smartphone look more sophisticated, improve the tactile sensation from touching the screen.

All flat 2.5D glasses, universal and model, do not completely cover the smartphone screen, but are glued with a millimeter gap around the edges, as in the photo below. Only expensive curved 3D glass will cover the entire front panel.

note that if a flat 2.5D glass is glued to a smartphone with sloping sides, then the accessory will either have the same screen, or there will be non-glued areas along the edges of the front panel.

What is this glass technology - let's try to figure it out.

For a long time, the English abbreviation xD has been used to denote the number of measurements, indicating their number. 2D is a flat two-dimensional space that has width and length, in the case of 3D, thickness or depth is also added. Against this background, the term 2.5D does not seem entirely clear: it would seem, how can you add half more to the two existing dimensions? But in reality, everything is much simpler.

2 D-glass

Traditionally, displays on mobile devices have been equipped with a transparent plastic protective cover. Later (with the development of touchscreens and an increase in the screen area), tempered glass came to replace it, which was designed to increase the device's resistance to shock and scratches. However, the use of new materials did not change the technology itself. As in the era of plastic dominance, the display cover was a piece of glass cut into the shape of the front of the smartphone. It was conditionally two-dimensional, since the insignificant thickness of the coating (up to 1 mm, against a background of 5-7 cm in width and 10-15 in length) can be neglected.

The edges of 2D glass are processed at the factory to remove a sharp edge that could cut your finger. Careful grinding of the edges is not paid much attention, since in most cases they are recessed into the body or covered with a side edging. Thus, the user does not see the thickness of the glass: only the front surface of the coating is open in front of him.

3 D-glass

The term 3D glass (as opposed to 2.5D) was introduced even before the first devices using this technology appeared. Smartphone manufacturers have been on fire for a long time with the idea of ​​a curved screen, but for a long time the level of technology did not make it possible to create a matrix high resolution other than flat.

IN 2013 year Samsung and LG announced smartphones Galaxy series Round and G flex with curved displays. In such screens, a glass layer covers the matrix, repeating its bend, and the third dimension (thickness or relief - as it is more convenient for anyone) is always in sight.

2,5 D-glass - the golden mean

2.5D glass, as you might guess from the above, is an intermediate option between 2D and 3D. This coating is used to protect conventional flat screens, but differs from 2D with rounded edges. It allows you to give the display a three-dimensional effect, round out the outline of the case, make it visually smaller and more sophisticated. The main advantage of 2.5D glass is the ability to obtain a slight bend without resorting to the use of expensive 3D matrices.

One of the first modern smartphones, which received a screen with glass smoothed around the edges, became the iPhone 6. But Apple never used the term "2.5D glass" in relation to its products. In 2015, Zopo Touch was advertised as one of the first 2.5D smartphones.

If you dig deeper into history, you can see that curved edges were encountered even when touchscreen smartphones were just gaining popularity. In 2009, the Nokia 6700 Slide had a similar coating, and in 2011 the touchscreen N9 was released. In the same year, HTC introduced a device whose screen had rounded edges, but they were curved upward rather than downward, forming a small depression.

In conclusion, it is worth noting that 2.5D glass technology is a good technique that allows you to add variety to the design of mobile devices. But it is not something new and revolutionary, but just serves as an example of how old technologies are taking on new life.

2.5D glass is not without its drawback: when pasting a regular protective film or glass, it will not be possible to completely repeat the shape of the screen, and an air gap forms at the edges under the coating, but it copes with these bends and adheres perfectly, covering the entire surface.
