Where should mobile device screens evolve?


Where should mobile device screens evolve?

One of the great attractions of mobile devices, whether smartphones or tablets, are undoubtedly their screens, and this is a section in which manufacturers have always paid close attention, something that makes clear the spectacular evolution of which we have witnessed in just two or three years. Of course, the improvements that have been introduced have to do with very different issues, but it is clear that the absolute protagonist has been the resolution, and there is no better example than to think about how the Apple Retina screen has been left behind in this regard. Should we expect the trend to continue or is there other sections What are becoming more important?

Do we need 4K screens?

The resolution has long since Quad HD It has become the norm in high-end tablets and in recent months we have seen that almost the same can also be said of higher-level smartphones, even if there are still some manufacturers who are clearly reluctant to make the leap, presumably because of the costs in fluidity or autonomy that may have for their devices, and many will argue in their favor in the sense that the improvement in resolution comes at a point where the sacrifices that may have to be worthwhile cease be done in other sections. The doubts multiply, obviously, when we talk about Quad HD screens, but Ultra HD, even if this year the first phablet has come to light with 4K screen (the Xperia Z5 Premium), although precisely the limitations in which image is reproduced with this resolution can be considered proof that we may not be prepared. The truth is, in any case and although we must always be cautious with this type of forecast, it is that it does not seem that we should expect a new jump in the next year and everything indicates that the race has slowed quite momentarily.

More OLED screens?

Samsung AMOLED

Along with the jump to the Quad HD resolution in high-end smartphones and phablet, it is impossible not to appreciate that there has been an almost equal magnification in terms of the type of panels used, with an increasing number of devices that have abandoned the screens LCD in favor of AMOLED, mainly due to its lower consumption. The difference is especially noticeable precisely among those with higher resolutions and, although there are some exceptions, the AMOLED-Quad HD tandem seems to be the dominant one now. Even in the field of tablets Samsung He has dared to introduce this type of screens, although it is true that here it seems that the rest of the manufacturers are not launching to follow in their footsteps yet. The final victory of the OLED screens seems so clear right now that the rumors that Apple will also mount them on their iPhone in the near future They do not stop, although the latest news affirms that this will not happen in 3 years.

Technologies to reduce consumption

We have already said that one of the main advantages of AMOLED screens is their lower consumption, something vital when such high resolutions have been reached without the capacity of the batteries that support them have grown in the same way, before on the contrary, we are seeing that in a few models they have even been reduced compared to previous generations in order to respond to the fashion of thinning our devices. However, this is not the only effort manufacturers are making to try to reduce the consumption of their devices and, if Samsung had long since introduced in their Galaxy Note the option to see the screen in grayscale to reduce energy expenditure, we have also witnessed in recent months some interesting innovations in this regard, as is the case of the "secondary screen" of the LG V10, which enables a small area of ​​the screen to display information independently, or the technology that allows the Lumia 950 XL Show us notifications with the screen off. Undoubtedly, this is a path by which we expect further progress in the future.

Improve image quality without increasing resolution

Can we expect the image quality to continue improving even though the resolution does not? Of course, since, as we never tire of repeating, there are many other factors that have to do with it, such as the levels of contrasts, the fidelity of colors, the levels of brightness or the viewing angles. If the screens of smartphones and tablets of Samsung High-end are victorious lately over and over again from the analysis of experts in recent times is not to have a resolution superior to that of others, but precisely to stand out in many of these other sections. In fact, we've seen so much with the Xperia Z4 Tablet as with the screen Quantum Dot of the LG G4 as other manufacturers are also beginning to place much emphasis on the evolution of their screens in other directions and, although it seems that OLED screens will take time to reach the iDevices, yes it has been discovered that Manzana He works in secret facilities to make his own screens, lighter and with higher levels of brightness.
