What are 2.5D screens?

A 2.5D screen (or contour screen) is one whose edge has been slightly contoured That is, the glass at its edges It has a slight curve, the result of the polishing carried out. Be careful, we are not talking about a true curved glass, but the edges have been lowered to generate a softer sensation. The edges of the glass panel are not rectangular, they have been rounded slightly.

This image explains in a very visual way what a 2.5D screen is and what its differences are with respect to other types of screen:

Are 2.5D screens good for anything?

2.5D displays have a mainly aesthetic functionality The effect they generate is attractive, and that is why manufacturers choose them. However, they also allow new designs. With a 2.5 screen, the protective glass can exceed the frame of the smartphone. Because the edges are smooth and curved, the user will feel no friction.

In fact, some devices include 2.5D screens that are not very noticeable, but that avoid uncomfortable rubbing against the edgesIt should also be noted that contouring is done at the end of glass manufacturing, and it can be applied to popular compounds, such as Gorilla Glass, but also to other more common ones. Of course, the screen itself is not affected, only the glass that covers it is modified.

It is clear that 2.5 screens do not provide much real utility, but they have become very fashionable. Models like the latest iPhone or Nexus have used them, and now even are reaching the mid-range Although there are also really curved screens like the SamsunG Galaxy S6 edge or of the LG Flex 2.

2.5D displays have a future

When we saw them on the iPhone 6, the 2.5D screens seemed very premium, but right now there are models under 200 euros with them. In the future will be popularized, since its cost is not much higher than opting for normal glass. What's more, some screen savers offer 2.5D effect as well.

Speaking of protection, a 2.5D screen is more prone to breaking than a normal one. It protrudes from the frame of the terminal, so a blow affects it more… although the difference is not abysmal either, in any case they are quite delicate.

So you already know what 2.5D screens are The truth is that they give a distinguished touch to a smartphone, so it is normal that brands bet on them more and more. Certainly a small detail that makes all the difference for aesthetically conscious consumers.

What do you think of 2.5D screens? Did you already know what they are, or didn't you give this design trick a name?
