Users do not need to 4K five major causes of screen phones

　　As far as phoneArena reports, if the rumors are true, Sony may be for mobile phone (Xperia Z5 Premium) 4K displays the first smart phone manufacturer. Due to the rumored Xperia Z5 Premium configuration 5.5-inch display, which means its pixel density will reach incredible 805ppi.

　　Prior to this will allow Sony to enter no other manufacturers entered the field. Currently, Samsung is the pixel density is the highest number of Smartphone manufacturers, such as Galaxy, S6, S6 edge, S6 Active pixel density and S5 LTE-A all 576-577ppi. Although not available in configuration QHD (1440 x 2560 pixels) resolution display phone, rumored Sony will Smartphone screen pixel density increased to more than 800ppi.

　　However, we need to configure such high pixel density display smart phone? the next few years, mobile phone manufacturers will put these technologies imposed upon us, but we had at the end of this year, anxiously looking forward to the 4K-screen phone's sense of reason?

　　Although no one don't like the revolutionary advances in mobile phone technology, but there are reasons that we do not need the 4K-screen Smartphone:

　　1, current chipsets do not handle 4K very good image

　　It is reported that the Xperia Sony Z5 Gao Tongxiao Dragon 810 chip will be configured. Put aside problems such as fever or not, this chipset does support 4K display, but we have never seen before Xiao long 810+4K display phone. This makes us consider: in a drive when there are so many pixels display, Xiao long 810 Adreno 430 of its Integrated GPU (graphics processing unit) performance?

　　2, battery life may be shortened

　　Higher pixel density display means no doubt will shorten battery life, batteries and other parts inside, optimizing is important, but unless manufacturers can find a new way to extend the battery life of a Smartphone, you can imagine the 4K screen phones battery life is difficult to surprise. Sony has always been known to optimize energy consumption, so if Sony proved it again in this area of technology, we would not be surprised.

　　3, the user may be difficult to find differences between 4K and QHD display

　　Although tests showed that people can "see" the difference between 1080p and QHD display, but we can't be sure the vast majority of people are able to distinguish between the same size QHD display quality and 4K the difference. To the human eye, both resolutions are clear, hardly identify a single pixel. However, to provide users with the latest technology, is an effective marketing tool, index higher products sell more easily.

　　4, you don't care about virtual reality helmets

　　Often mentioned the future of mobile 4K display in part because virtual reality. Virtual reality has begun to become a scenario for Smartphone. Current virtual reality helmets are often used in conjunction with smart phones, such as Google's Cardboard, due to the resolution of the eye by two "split" (called "screen door effect"), which makes virtual reality there is a certain amount of grainy images sometimes. For users not interested in virtual reality and virtual reality helmet, why want to 4K screen cell phone?

　　5, 4K limited

　　If you do not see the 4K content, user is unable to fully leverage the power of 4K-screen phone hardware. YouTube has a few of the 4K video, Netflix and Amazon has only a few 4K videos. 4K video is not yet mainstream video industry.
