Let's shed some light on smartphone displays with these 6 facts

Learn what matters (and doesn’t) to the naked eye

Bigger is better. It's all about the size. Or so you thought was the case with smartphones when you're scrutinsing their display quality.

Yes, a smartphone is mostly a slab of display. Thus, it is incredibly important that you know these things about your screen to make the right choices in the future and how best to take care of your existing one.

So if you want to really see those amazing details on your Instagram feed, or spot even the finest details when you're watching a full HD movie on your latest and greatest smartphone, this is our freebie to you. A guide to Smartphone 101: Introduction to Displays.

PPI matters

You see, the naked human eye isn’t perfect, especially if you’re old enough to have subjected your eyes to too many sessions of computer use.

A person with perfect eyesight is said to be able to see up to 876 PPI with a display that's four inches away (and also the closest the human eye can get to focus). You can't go wrong with anything above 300 PPI, but the best we'd ever need for a smartphone display is probably a max of 720PPI. 

At the end of the day, it's not about the numbers, but the experience. So go try the smartphones out for yourself and see which looks best. More often than not, the only way you're going to note the difference in resolution is when you hold two smartphones side by side.

And that's hardly going to happen. Well, unless you're like us, carrying two smartphones for the sake of testing. Such a bother.

Different types of displays for different purposes

OLED, AMOLED, Super AMOLED, LCD, IPS LCD - who can keep track of them all? We know it might sound confusing, but these are the only things you really need to know.

LCD stands for liquid crystal display. IPS LCD displays are what you get in your high-end smartphones and they provide better viewing angles, drink up less battery juice, and provide greater visibility in sunlight as compared to TFT LCD displays.

As for OLED (organic light emitting diode) displays, they save battery as they do not require a backlight panel and better visibility under direct sunlight due to the better contrast. But they also get old with time, resulting in duller displays. Fortunately, that's not an issue. Chances are you'd have changed your phone before the screen ageing sets in anyway. 

Curved displays are not a gimmick

Curved screens might sound like the latest sales ploy by tech companies, but it’s not just superficial. There’s actual truth behind claims that a curved display is a helpful feature (gasp!). Wipe that look of shock and distrust away.

The curve provides a better viewing angle, as reflection and distortion are reduced, even if they’re not completely removed. Also, considering that we aren't mutants, our eyes are spherical. Thus, they would fare better when a curved display emits light that falls squarely on our curved eyeballs.

Plus, (and this isn't really related to your vision), a smartphone larger than 5.5 inches is likely to wind up having its microphone too far away from the user’s mouth. Think of what a gentle curve can do - crystal clear conversation since you're now speaking directly into the microphone.

Shield your display panel from direct sunlight

It sounds like common sense - never, ever expose your smartphone to direct sunlight. But why, you ask?

Your smartphone’s display panel could possibly be damaged after prolonged exposure to direct sunlight. It won’t happen quickly, but when you notice the display panel showing signs of wear, it will be too late and costly to repair. Prevention is better than cure. Turn your smartphone face down if you really have nothing to shield it from the sun’s rays with.

Don’t keep the display on for too long

When you leave your gadget on without using it, it may lead to screen burn-in. What’s that? It’s what happens when pixels are unevenly used, with some colours burning brigther than others, over a prolonged period of time resulting in a patch of discolouration on your screen.

Don't leave your phone idle for too long, and turn on autolock so that your smartphone's display automatically switches off when it's not in use. It's also best not to stay on the same screen for more than 20 minutes if you can help it.

Safely clean your smartphone

If you have the usual fingerprint smudges on your phone, gently wipe it away with a dry microfibre cloth. If the stain proves to be more stubborn (we don’t want to know how that got there), wipe the stain off with a damp microfibre cloth. But before you do, remove the battery from your phone - take all precautions to prevent any short circuiting from the water. 

Another, very important point to note - never use any cleaning liquids on your phone. Certain screens can be covered in special coatings that could be damaged by the chemicals in the cleaning solution you're using.
