Pixels per inch, or PPI, determines your image/screen quality. Smartphones have been racing to outdo each other with just about every stat there is, from screen size to mega pixels on their camera. Still, there is a limit to how high a PPI can go. Manufacturers are currently struggling to get over 500 PPI for a Smartphone. For example, TV they have 4K definition, but the way PPI works it means the screen has to be 80 inches and you will often find that bigger screens have a higher resolution but lower PPI.
The Japanese are bragging that they are close to creating the world’s smallest 4K screen at 12.1 inches that will have a PPI of 365. They also claim that they are progressing so fast that they will be the first to create a working 5.4-inch screen (1440 x 2560) that has a pixel density of 543 PPI. Maybe they will fail to the point where such devices never hit the market, but the fact is that getting a higher PPI and resolution is a tough job. You will see an 18-mega pixel camera in your phone before you are able to buy a 543 PPI screen Smartphone. Here are a few Android phones ranked by their PPI rating.
1 – HTC One (2013) 468 PPI
It only has a 4.7-inch screen, which is good because it is slightly larger than most phone screens, but there are others on this list that are bigger and have to suffer a PPI loss because of it. Still, this has the highest PPI as per the end of the year 2013 (on the commercial market). It is 101% sharper than the average phone.
2 – LG Nexus 5 445 PPI
At 4.95 inches, it is very impressive that they have managed to squeeze such a high PPI amount into their phone. The phone is 91% sharper than the average Smartphone.
3 – HTC One (M8) 441 PPI
HTC ranks high again. This one has the same PPI as the phone below, but it has a 5-inch screen, which means it is slightly more impressive because it has a bigger screen. It is 89% sharper than your average phone.
4 – Samsung Galaxy S4 441 PPI
It has a 4.99-inch screen, so again it is impressive that they have managed to squeeze in such a good PPI rate. It is 89% sharper than the average phone. People may find ways of cramming more PPI into a phone, but as for now it seems like something that is not that scaleable. Still, it is almost impossible for most people to tell the difference between the sharpness of the phones on this list.
5 – Samsung Galaxy S5 432 PPI
A 5.1-inch screen with such a high PPI is still impressive. It is 85% sharper than most average Smartphones. You may notice that most phones on this list have a massive battery, for example, this one has a 2800 MAH battery, and part of that is to do with the display taking up so much power.
6 – Sony Xperia Z2 424 PPI
It has a 5.2-inch screen and is 82% sharper than the average phone. You may have noticed that as the screen size goes up that the PPI goes down. This is evident throughout the list with the exception of number three and four on this list (though the screen sizes differ very mildly). As you can see, if you want a larger screen for your Smartphone, then current technology and design is going to demand that you have a slightly lower PPI.
7 – LG G2 423 PPI
It has a 5.2-inch screen, which means that it is a full 82% sharper than the average phone. The fact it has a larger screen is why it is not the tiptop PPI amount, and yet it is far sharper than most phones you are going to find on the market.
8 – Samsung Galaxy Note 3 386 PPI
This does have a 5.7-inch screen that qualifies it also as a phablet. That is a term used to describe a phone that can also work as a tablet because it has a screen that is big enough. In this case, the ranking system with PPI is unfair because this phone has a big screen and yet its PPI still makes it 66% sharper than the average phone. So, do not judge everything by pixels per inch.
You might have thought what is coming in near future in the markets. What limit will be set by these phone makers in making their screens even more clear and crispy, In this regard we have some leaked reports from the Korean Smartphone makers Samsung which shows that they are ready to introduce the 562 ppi display in their upcoming devices somewhere in 2014. This will tend to change the screen resolution of the device as well which is most probably 2560 x 1440 p.
Beside this there are some news for the Ultra HD display that will be released by the company having that Ultra HD resolution of 3840 x 2160 pixels and pixel per inch density of 600+, which is twice as good as the phones we currently have in the market.
