1080P Full HD Phone Status: Looks Beautiful Smartphone hardware using the Android system has developed rapidly. In less than half a year, it has transitioned from a dual-core CPU to a 4-core, and the screen has grown from 720P to 1080P. This development speed is much faster than that of computers.

It is true that 1080P looks beautiful and is an unstoppable historical trend. But where is the problem at this stage? The author of Sina's record book analyzed the development status of 1080P mobile phones at the current stage:

Trends and Limits The first time people praised the beauty of the mobile phone screen, they should start with the iPhone 4. Apple gave the definition of the Retina screen at the conference and the iPhone 4's screen really made everyone excited.

I selected several representative mobile phone products in recent years and analyzed their pixel density (ppi) trends.

1. Nokia 7610 2.1 inch 208×176;

2. Dopod 818 2.8 inches 320 x 240;

3. Google Dream (G1) 3.2 inches 320 x 480;

4. Motorola XT702 (milestone) 3.7 inches 854×480;

5. iPhone 4 3.5 inch 960×640;

6. Millet 2 4.3 inches 1280×720;

7. HTC Butterfly 5 inches 1920×1080

Looking back at history, we can see from this picture that the mobile phone screen size and ppi have been improving. I believe that with or without Apple, this is the general trend of the display, but Apple has pushed history a bit earlier. I also believe that larger, clearer screens are an irresistible trend.

But there is no limit to technology, but human eyes have limits. There is a law in the digital product industry that when most device configuration parameters go beyond a certain point, this parameter may not have much practicality at all. This has been verified by PC products.

Regardless of the complicated parameters and technical terms, the two Android phones currently visible in China are all 5-inch screens. The manufacturer’s promotional slogan is “the screen of the 50-inch TV is loaded into the pocket”, from the actual In terms of effect, their clarity and resolution are indeed impeccable on the phone screen. But the eyes of consumers are becoming increasingly numb. Most people see the full-HD screen as just a reflection: "It's better than 720P," and it's no longer the first time you saw the iPhone 4's surprise.

Restricted space for play From the user's point of view, where can they experience the full HD screen advantage? Most mobile gamers say that they watch video, but even the more highly compressed 1080P movies are still around 10G. Even if there are not many other things, the 16GB storage space for the Butterfly and the Find 5 can only hold one movie. Although higher-capacity versions can alleviate this problem to some extent. For mobile devices, the "cloud" is the next trend, but the existing network is clearly unable to meet the demand for high-definition.

Another factor constraining this screen is electricity.

I once personally experienced it on the subway. When the Butterfly battery had 14% left, I used it to watch more than 20 minutes of 1080P video.

When the cell phone's processor is comparable to a computer, and the screen is finer than the display, battery technology has been stuck for a long time. The new battery is still in the experimental stage. The method to effectively extend the mobile phone time is simply to increase the capacity. This will make the mobile phone's shape out of tune with the existing aesthetic standards. Users do not like it. Manufacturers are mostly reluctant to take the risk. .

Developers' confusion Compared to the numbness of the eyes, the bigger problem was in the software. The author asked several developers about the 1080P screen. Their biggest complaint was that the software package was too big.

The source is not the technical difficulty but the resolution.

Android SDK development is divided into three types: high school, low school according to the density of points, and developers can make corresponding versions according to requirements. The former 720P is a high density. However, in fact, there are developers who do not develop according to these three specifications for more precise matching, and there are people who plan to use multiple versions to use one specification. For example, the 960*540 and 1280*720 resolutions are developed according to the same specifications. Slightly unclear, the stretch is generally not visible to users." This is one of the reasons why Android is not as exquisite as the iPhone.

When 1080P appeared, its requirements were even higher than the previous high density requirements. In order to adapt to a variety of resolutions, the software package has to be made very large, which causes troubles for wireless downloading; if the resolution is divided into different versions, the software package can be smaller, but it will also bring problems to the promotion. : A large percentage of users do not even know the resolution of their mobile phones, so that they can determine which of them is a bit difficult.

In addition to the package becoming larger, the UI design of the software is also a difficult problem. Larger and finer screens make it difficult for users to operate with one hand. Developers gradually use gestures to replace function keys such as “back” in the corner, but gestures are not as good as buttons. Intuitive, there are learning costs for the user. In addition, they also have to consider another version for the Android tablet, because it takes into account the use of flat screen landscape.

Manufacturers follow and look at mobile phone manufacturers, heap hardware has become Android they have to do a thing.

At the 2010 CES show, the dual-core mobile phone was a symbol of status. Today, dual-core has become the standard for thousands of mobile phones. There is no quad-core that I am sorry to say that he is the flagship. Although everybody is shouting "experience" and "optimization", as long as there is a home with four cores, other manufacturers must follow suit and use the fastest products at the same or higher level. CpU frequency became the yardstick for measuring the technical level of manufacturers, and running points became an indispensable performance show at large and small conferences.

After the processor has evolved to quad-core, the handset hardware has experienced excess performance. At this point, the screen is another way, and the relatively invisible performance, the obvious screen changes, of course, is more likely to cause goodwill manufacturers, manufacturers have high value-added products, the 1080P screen can both please consumers but also To create higher profits for themselves, why not do it; and for those second-tier manufacturers, when the high-definition screen has not been popular, most such a mobile phone has become a shortcut to close to the first-line manufacturers.

The 1080P at this time is not a good or bad question, but there is no problem. It has replaced the quad-core and become the new flagship.

This is the status quo of 1080P. It is an irresistible historical trend. Mobile phone products are now entering the era of Full HD. We believe that next year's CES and WWDC will be the beginning of the big era of 1080P Full HD screens, and its popularity will be faster than the previous WVGA or 720P screens, but the resulting pain is also inevitable. This is The problem that open Android will inevitably encounter is the status of Full HD mobile phones.
