There are exactly 9 years, on September 23, 2008, what would become the most used mobile OS in the world was finally announced: in a partnership with the Taiwanese manufacturer, HTC, Google launched the T-Mobile G1 - the first Android in the world and the 'serious' competitor to the iPhone. 6w1j4e
Since then, a lot has changed in the technology of smartphones – in addition to becoming much more popular, powerful, accessible and diversified, have grown in size, something that, at that time, practically no one expected.
with a screen of 3,2 inches, the G1 was smaller than the first iPhone and, believe it or not, its biggest asset was having a physical keyboard – meaning that when it came time to send emails, exchange messages and surf the internet, you wouldn't have to use an abominable virtual keyboard, the most hated part of the screens touch screen (at least in the beginning).
Unlike iOS, which until then did not even have that name, Android was not very visually coherent: the system had elements of different sizes and locations, which forced most manufacturers to fill their smartphones with physical keys.
buttons, buttons buttons 2n3v3c
If we look at all smartphones pre-2010, it is possible to notice a considerable amount of buttons in the vast majority of them. In some cases, like the first Samsung Galaxy (i7500), the number of physical keys was such that only them could already access most of the device's functions.
However, although the Samsung continued with the huge number of buttons in the following releases, it was also a pioneer when it came to replacing the physical keys with more display: together with the Xperia X10, the first Android of the, until then, Sony Ericsson, Galaxy S was one of the first smartphones in the world to feature a 4-inch screen – the resolution on both models was approx. 480 x 800 pixels.
Equipped with a screen considered 'much bigger', these devices abandoned part of the physical Android keys and started to focus on their system interfaces: without knowing how many legal problems it would have soon after, Samsung debuted the TouchWiz and Sony, in turn, introduced to the world what was called Timescape, the official skin of the Xperia.
the interfaces 733h6l
The great truth is that, until HTC develop the first Sense UI, in 2009, the manufacturers didn't care much about this skin talk. Android was pretty much the same on any smartphone, but companies soon saw that this was bad for business:
Having your own interface was (and still is) a means of tell apart your product from the rest: at a time when all smartphones had equally limited screens, cameras and hardware, only one design and one software exclusive access could stand out.
At the time, Samsung was 'smart' and decided to be inspired by the most beloved interface of the moment, the iPhone.
O Galaxy S had strong iration for the apple device – in addition to having a similar format on its exterior, Sammy's interface had various iOS elements: the four shortcuts at the bottom of the screen, the square and rounded corner icons, the black background in the app drawer and several other visual aspects that, when known by the competitor, triggered one of the most costly court battles of technology.
In mid-April 2011, the Apple decided to sue Samsung in the US for stealing the 'look and feel' of the iPhone with several of its Android devices, starting with the Galaxy S itself. It is worth ing that, 4 days before launching its gadget, back in 2008, the company ed 4 Patents iPhone and its software.
added to the others 189 Patents taken months later, these four screenshots caused Samsung to be ordered to pay $1 billion for damage to Apple's intellectual property – this story is not over until today, but we need to get back to our theme: displays.
When size became document 12383z
In addition to being the great Showcase of our smartphones, screens are the main means of interacting with what is shown: whether you are watching a movie, playing games or browsing social networks, it's your fabric, assisted by the rest of the hardware, that will make this experience nicer.
That's why the same manufacturers didn't take long to realize that the screen is serious: although it wasn't the first big jump in the size of displays, the first Galaxy Note, the one released in 2011, was seen as a real aggression to the common – its AMOLED screen had 5,3 inches and HD resolution.
At first, the media didn't pay much attention to the device: it was too big, too expensive and, although it had interesting features, the Galaxy SII was more realistic with their 4,3". Apple, which the year before launched the iPhone 4, also demonized larger screens – according to Steve Jobs, the iPhone screen is designed so that you can operate it with one hand, reaching the top and bottom of the device without straining your thumb.
Laughs in iPhone 6 Plus language.
Two years after Jobs' declaration and three years after its competitors, the Apple also surrendered to 4 inches and launched the iPhone 5 – this was the first time that a aspect ratio narrower helped in handling a larger phone.
On the other side of the play, the Samsung extrapolated the limits of the acceptable with 5,5" on the second Galaxy Note. But hey, the first one had already been a success, unfortunately for journalists, and this new one had a screen that was a little narrower: the aspect ratio had jumped from 16:10 to 16:9.
It doesn't even seem like this talk aspect ratio It's so old, right?
'Resolution' 233l2n
Well, when the size of the displays ceased to amaze s, resolution and pixel density have become the new point of contention between manufacturers. in the middle of 2013, most of the tops of the line already had screens Full HD.
Added to the average size of screens at the time, the 1080 pixels formed up to PPI 450; and according to Apple, 300 PPI was enough for the points to be invisible to the naked eye.
This average only changed in May 2014, when the G3 was released by LG. The device brought 5,5 inches of screen, edges much smaller than that of its opponent, the Galaxy S5, and a resolution of incredible 1440 x 2560 pixels - was the first 2K on a commercially relevant device.
Although the fashion of G3 inspired its successors, the device was technically ahead of its time: in addition to being unremarkable in the eyes of most, the screen 2K sucked up processing and battery. In theory, the Snapdragon 801 I was even prepared to deal with a large number of pixels, but it was evident that it worked better in traditional resolution.
Finally, as the months ed, the screen 2K fell in favor of other releases as well: Samsung sured 1080 pixels with the Galaxy Note 4 and, although the Moto Maxx is from October 2014, Motorola already integrated a display of the kind in the Nexus 6, released in September.
Nowadays, few question the existence of displays 2K. Although they continue to consume a lot of battery, they are indispensable to enjoy the virtual reality (VR) with higher quality.
TFT, AMOLED, IPS, IGZO… what is all this? 495z3n
Being one of the most important parts of the experience of a , the different screen technologies are much older than you think: the AMOLED has been present in the Galaxy line since its first model (the one full of buttons mentioned above), and the IPS, which has always been competitors' answer to Samsung's screens, appeared first on iPhone 4.
The main advantages of an AMOLED screen are related to the fact that its pixels have own light. This makes it possible for them to individually turn off and create a so-called 'deep black', plus AMOLED screens are more economical energetically.
On the other hand, the IPS It also has its advantages: because they are backlit, IPS s tend to be brightest than AMOLED s, moreover, this technology does not suffer from the degradation of blue pixels.
In the case of OLED technology, the blue diode degrades faster than green and red, causing the device's screen to lose quality after a few years of use.
There is no such thing as a perfect display, but both technologies have reduced their major flaws over time. Currently, it is possible to find displays Phosphorus IPS, such as those used by Sony, which achieve nearly so good as those of an AMOLED. Samsung's latest screens, on the other hand, manage to have great viewing levels even under the sunlight.
4K, HDR and the future 5g911
Although Sony was one of the last to leave TFT screens, doing so only in 2014, the Japanese company was the first in the world to bet on 4K screens. O Xperia Z5 , released in 2015, has four times the HD resolution (720p) and best of all: it only becomes 4K, in fact, when used to play some video or display photo.
This dynamic prevents the Z5 from having the same problems as the LG G3, saving battery and also processing.
In 2017, the manufacturer bet again on the idea and brought us the HDR is a standard exported from cinemas that allows finer adjustment of the parameters of heart e contrast of image.
In other words, the variety of tones that can be reproduced ends up being larger and, consequently, more faithful to reality.
In 2K devices, the first model to have an HDR display was the LG G6, which in addition to having much thinner edges than the Xperia, debuted the screen ratio in 18:9 – not only making the device narrower, leaving its footprint more ergonomic, an 18:9 screen can be split more symmetrically.
And although many credit thestarted to be sold in other countries.
In 2017, the fashion of displays 'infinite', as Samsung calls it, spread and we had a wave of different practically borderless models: presented in March of this year, the Galaxy S8 e S8 + are two of the most iconic examples of this segment – and not only because they bring extremely thin edges, but because they add this technology to the proportion. 18:9 and the curved sides of the previous generation.
In addition to making the display look more like a movie screen, the 18:9 aspect ratio, also exploited by LG G6, makes the device much more comfortable in the hands – the phone gets longer, but the reduction of the edges makes up for this point.
But that's not all: for the first time in history, the concepts of devices with a borderless screen weren't too 'insane' to be true, so much so that the most conservative smartphone in the world, the iPhone, decided to change and also adopted a screen borderless.
Apple has invested heavily in the display of the iPhone X, which also has virtually imperceptible edges. We already iPhones 8 e 8 Plus, the company hasn't changed much, but it has brought in True Tone technology, which adapts screen tones to ambient light.

Even though they are somewhat inaccessible to the West, it is undeniable that the success of Mi Mix and Aquos Crystal decreed the next step of the technology of displays: during the next two or three years, it is possible that the main trend among future devices will be precisely the 'reinvention' from the edges completely.
While Samsung found a way quite balanced to keep sensors and the maximum screen in front of its Galaxys, Apple wants to make the 'bar' of the iPhone X something that makes it as recognizable as the home button that X himself retired.
So, after so much discussion right from a single component, it is clear that while we always see important improvements in cameras, design and performance of our devices, it is in the fabric which is the real 'magic' from each top of the line.
O it's not just the region most observed of a smartphone, but it is also the most played, the one that has gained more space in recent months and, as we showed at the beginning of this text, it is the most efficient way to interact with so much information and technological capability.
Um viva to displays.
