Smartphones are the demand of the century and the most commonly found object in most of the households. Such is the addiction that morning sets into evening in no time, while we are busy gawking at the screens of our smartphones, aware yet unaware of what’s happening in the world around us. A question arises. How much do you know about the thing that you dedicate most of your time staring at?

Here’s a guide to smartphone displays for all the dummies who might practically ace at texting with Quicksilver speed but scratch their heads when it comes to the intricacies of the tech world. If you are anything like me, read on –


When buying a phone or through the ads on your flat screens, you surely must have come across digits written besides the screen resolution but the gravity of it ain’t known to you. Let me make it easier. Now any picture or image that you see on your phone screen is made of picture element known in the tech world as ‘pixel’. Resolution is just the size of the screen expressed in terms of pixel, i.e. the number of pixels horizontally multiplied by the number of pixels vertically. Now, the higher is the number of pixels for a fixed screen size, the higher will be the resolution and sharper the display. High definition or HD screen definitely has better resolution while a full HD screen displays top even that.

Another term that one might come around with respect to smartphone screen resolutions is PPI which stands for pixel-per-inches, the number of pixels packed in every inch of the screen space or in short the pixel density.

Should one settle for more or less of the PPI?

One must always settle for higher PPI phones simply because Higher PPI = Sharper images. But there is a limit to which smartphones must keep the PPI, and the reason being that human beings fail to view image clearer after a certain increase in PPI. Another significant reason for PPI restriction is that very high PPIs negatively affect the phone performance by draining the phone’s battery.

So, which is the right display?

Well, when it comes to display, one must at least go for a phone with 720p HD resolution. A higher resolution would give you an even finer phone experience.

Display Types          

Although there exists various terminologies in the smartphone display dictionary with respect to its types (Quantum LCD, SLCD, Retina etc.), there are two significant displays types that are commonly out and about in the phone market, and they are – LCD and AMOLED. (Naam to suna hi hoga!) Now both these types bring into use different technologies for the color and light.

LCD – Liquid Crystal Display or LCD are backlit, power-efficient, extremely bright, coming with the ability to precisely display the entire spectrum of colors. They are made up of pixels which have green, red and blue sub-pixels which when light is passed through them, make the pixels acquire innumerable colors.

AMOLED – Active Matrix Organic Light Emitting Diode or AMOLED contain pixels that are all separately powered. This means that individual pixels can be turned off. The sub-pixels in AMOLED create their own light and the need for a backlight does not arise. Although it displays amazing deep and black contrast, other colors may not be as accurate.

Such displays may be good for watching videos but not reading, and another minus is that these perform poorly outdoors.

IPS – The newest inclusion to the list of display types is an IPS or In-Plane switching, and it comes with a wider viewing angles and color reproduction. Best suited for reading addicts, it can provide a good blend of brightness, color reproduction, sunlight usages and power-efficiency.

Now that you are ready with your own stock of smartphone display gyaan, pass it on and educate the world. Earn the graces, people.
