The resolution of mobile phones has developed very rapidly, and has basically caught up with the development of tablets. 2012 can be said to be a year of 720P. It was the first time for users to experience high-definition images on the mobile phone screen. It was really amazing in the past, but at the end of 2012, there were even many 1080P resolution Our mobile phones have piled up. As consumers, how should we view 1080P mobile phones? Is high resolution only good? Let's take a look at the advantages and disadvantages of 1080P mobile phones.

First of all, 1080P mobile phones are mainly targeted at the Android platform. The Windows Phone platform and iOS platform are still at the maximum resolution of 1280 * 768 and 1136 * 640 due to the mandatory provisions of the manufacturer, while the Android platform has the highest 1080P full HD product, which is undoubtedly very significant for the improvement of user experience.

What are the advantages of 1080P?

Fineness

Of course, the most intuitive change of 1080P screen is the huge improvement of screen fineness. Even a 5-inch screen can reach an ultra-high level of 441 ppi. Now the top 720P screen is only 347 ppi at the highest level. This difference is still obvious. Here is the comparison between 1080P and 720P screens (1080P at the top and 720P at the bottom).

It can be seen that there are pixels on the 720P screen, while the 1080P screen is still very fine.

FHD level video

In addition to the direct visual impact, 1080P also makes it possible for mobile phones to play full HD video point-to-point. This shock effect is completely beyond the 720P screen.

Problems with 1080P mobile phones

compatibility

We all know the advantages of 1080P mobile phone, but what are its disadvantages? The first thing to bear the brunt is of course the issue of compatibility. It is famous that Android's hardware platform is fragmented. In addition to the differences in hardware platforms, mobile phone resolution also has various patterns, from the initial 480 * 320 of Android, to the later mainstream 800 * 480 (854 * 480 at the same level), 960 * 540 (960 * 640 at the same level), to the high-definition 1280 * 720 (1280 * 768 at the same level, 1280 * 800 at the same level), to the current top 1920 * 1080. The resolution of Android is too scattered, which will have a "disastrous" impact on application compatibility. Every time the resolution is improved, various applications will be incompatible. Among them, the compatibility problem of commonly used Android software is acceptable, that is, the problem of icon and text layout. However, the problem of the game is much more serious. Every time the resolution is upgraded, it often directly leads to the inability to play the game.

performance

With the sharp increase of the resolution of 1080P mobile phones, the load on the GPU has also risen. In the past, the mainstream 720P resolution on the Mali-400MP4 on the high-end quad core Exynos 4412 can only be said to basically meet the smooth operation, and this chip only supports up to 1280 * 800. After the upgrade to 1080P, the graphics processing requirements brought by ultra-high resolution have reached an unprecedented height. It is believed that only the Adreno 320 of Qualcomm can meet this condition for the time being. Whether it can meet the operation requirements of large-scale games is still unknown. Therefore, if we want to popularize 1080P resolution, we need to make a great leap forward in the performance of the mainstream mobile phone GPU, so that it is possible to meet the needs of improving graphics processing capacity.

other

Another problem to note is the practicability of watching 1080P video on mobile phones. At present, the ROM capacity of the mobile phone is about 16G, and the available space may be only 11G~12G. Users will also load various games and software. If the actual remaining capacity is still loaded with high-definition movies, it is estimated that the pressure will be great for the mobile phone. Of course, we can OTG To solve this problem, you can directly use the mobile phone with OTG to read the movies in the USB flash drive or even the hard disk. Even full HD video is not a problem. But there is also an extended problem, that is, many mobile phones do not support more than 4G single files, so it is also a very depressing problem that movies cannot be read. Of course, the most sad thing is that if 1080P mobile phones do not have OTG

In general, the development of mobile phones towards high resolution is a major trend. At the end of the year, several 1080P mobile phones have emerged, including HTC Butterfly OPPO Find5 Nubia Z5, etc. I believe that the competition in this high-end market will become more and more exciting.
