Vivo Xplay3S wave 2 k can screen the wind into the mainstream?
A, popularization, 2 k screen is what
As smartphones is becoming more and more tend to homogeneity in the hardware configuration, making the market competition is becoming more and more heated, in addition to the price war, differentiation, and so on marketing methods, in fact every manufacturer wants to occupy the high ground on its own hardware quality, but in JiZhan in September this year, and no one of the advantages, as everyone thought that at the end of this year in mobile hardware, vivo suddenly in its new flagship vivo Xplay3S played on the screen “” 2 k ace, surprise to the industry and users are surprised.
Followed by a domestic manufacturer also hinted that could release 2 k screen mobile phone, but then a netizen exposes a vivo internal mail, testified that vivo is currently the only can get 2 k mass production manufacturer of the screen, and the media also reported flagship samsung next generation may also will use 2 k screen, said samsung home 2 k screen is about to mass production, while LG and sharp screen such authority has ever said trying to develop mobile phone screen, 2 k has always a smooth transition of the powder filled the screen suddenly like CPU competition, so, what are the 2 k screen?Why 2 k screen can cause everybody’s question and discussion?We need 2 k screen again?
2 k here, it’s not that we talk about salary always say 2000, but a resolution, the official did not define 2 k, the so-called 2 k is a derivative 4 k.4 k believe that everyone in each home appliance manufacturers in a frenzy of propaganda to understand somewhat, simple says there are about 4000 pixels is horizontal resolution, is not like 1080 p (1920 x1080 pixels) is a constant value, but a range of values, then 2 k, there are about 2000 pixels, of course, is a horizontal resolution, is also a range of values, referred to in vivo of 2 k screen, is the value of 2560 x1440 pixel resolution (1440 p) there are media reports said the screen, it is important to note that most of the current domestic film institutes of digital movie and some of the older IMAX, use also is 2 k resolution (2048 x1556 pixels) sources, so the vivo will release the 2 k level message screen, will cause the users and the media talk about and question.
Second, the question, we need 2 k screen
In the doubts, the loudest voice is “whether we need 2 k screen mobile phone” such remarks, some actually speak bluntly, is always in progress of science and technology, ordinary users can’t stop can’t or so, no matter you don’t accept, or willing to accept, the popularity of 2 k screen, even becoming the mainstream of the next smartphone configuration, this is without controversy, absolutely not because “need” such a problem.
For some reason, such statements are based on two points and said, one is the apple of the so-called “more than 300 dpi, retina, do not know the difference between the particle”, the second is “the higher resolution screens will lead to higher power consumption”, but is it really so?
Actually you overlook the details in the first point, that is visibility.When Steve come up with this conclusion, as looks something like this: “the roughly 300 dpi resolution is a magic point, if you take a thing to out eyes 10 to 12 inches (about 25 cm – 30 cm), the resolution limit of the retina can about this resolution.”Note that premise is 25 cm to 30 cm, and according to some research data released, people in the use of mobile phones and other handheld devices, most of the time is less than the sights, there is no so-called 300 dpi, of course, this is the same and we see a movie, do you see in the last row IMAX is clear, of course, but if you do it in the first row, still can obviously feel the sense of particles, the fact also proves that the cell phone on the market at present most of the 1080 p display effect is much better than the Retina screen iPhone5s, so want to obtain visual experience to the extreme, it must be perfectly PPI.
While apple’s latest tablet Air has already proved that to us, have significant improve in all respects, reduced battery case, also can get a longer battery life, this is because the screen of the Air used new technology, reducing the number of the original 84 leds to 36, at the same time of reducing power consumption have won the same display effect, so based on the same screen technology (IPS panel, TFT driver), under the principle of improving the screen resolution and maintain or even it is not possible for reduce the power consumption, finally the test is still 2 k screen and the technique and technology of the mobile phone manufacturers.
In “more than 300 dpi, retina, do not know the difference between the particle” and “the higher resolution screens will lead to higher power consumption” are not set up the case, would anyone put forward “do we need 2 k screen mobile phone” such a question?
Third, the question, 2 k technology bottleneck
, compared with 1080 p cell phone screen 2 k in the face of difficulty is far from being questioned so simple, alone a control as small as a mobile phone manufacturers have a headache, is enough to make the commercial mobile phone, the highest PPI is 4.7 inches 1080 p HTC one 469 PPI, and 2 k screen on pixel was 1.8 times greater than 1080 p, some media had previously said vivo Xplay3S PPI for 515, even if is such a big PPI, the vivo Xplay3S screen also reached 5.7 inches (vivo Xplay size), what’s more, there is no data shows more than manufacturers have mastered 500 PPI screen production technology, the vivo Xplay3S 2 k screen to face above all is the technical difficulties.
In addition, on the mobile phone overall fluency, and 2 k screen problem had to be taken into account.As is known to all, a maximum resolution for your mobile phone and computer, also limited to graphics processing module (GPU), while in mobile processors have been released, only 800 integrated Adreno330GPU Xiao dragon can support up to 800 x2048 resolution, vivo 2560 x1440 resolution adopted by the almost reached the limit of 800 Xiao dragon, in theory, more than 1080 p, 80% of the amount of calculation speed and memory for the mobile phone is a great test.
Besides fluency, storage capacity is also a problem, the resolution of the upgrade will mean most of the APP ICONS and graphical interface element size will also increase, so that to ensure the high precision on the vision, the resulting problem is the APP need to occupy a larger storage space, the apple after launched 2048 x1536 Retina screen has encountered barely 16 g version installed software is full.
Although according to the above two problem vivo Xplay3S adopted 3 g high-speed RAM and 128 g of the ROM to large capacity, but the actual effect, but also pass through the market test to know.In addition, the 2 k on the research and development of screen display technology, brightness, contrast value, color gamut, even touch accuracy etc. Maybe will become a new challenge, after all, from 1080 p to the 2 k is very large, is not a simple hardware stack, but rather a set of based on the ecosystem rebuilding and definition of the phone’s screen.
This question and doubt, once in 720 p to 1080 p also had had, but after all, 1080 p is everybody understand and familiar with, better technology is relatively mature, so such doubts didn’t last long was submerged by numerous 1080 p cell phone, but the concept and technology of 2 K is small, there is even a friend asked the author, 2 K is too cheap, why not 2.5 K, visible for 2 K screen face is not only a question and doubt, there are more profound to the masses what to accept, understanding, and understanding, need vivo and other manufacturers to prove, confirmed and lead.
