What makes a smartphone display good (or bad)?


A display makes or breaks a smartphone. So a good display is of the highest importance to a smartphone as it is the primary means of how you interact with your smartphone. But, over the years, different display technologies have popped up, each with their own set of features and resolutions. If you’d like to learn more about smartphone displays, this is the article for you.

The first question that needs to be tackled is:

How does a smartphone display panel work?

The basic building blocks of displays are pixels. The resolution and type of each display is based on the number of pixels there are as well as the physical size of the display. These pixels in turn are made out of three individual color sectors: red, green, and blue. So, when a display does its job, each of the colors in a pixel light up really fast or turn off in the same manner to provide you with a moving image. And the way in which these pixels light up determines the type of display.

But there are also a number of other factors to consider when checking out a good display. Namely: the resolution (along with the type of the display). Other factors like viewing angles and color saturation help determine how good a display is.

So, let’s begin with the first major factor: resolution.

What is resolution?

Resolution can be defined as the number of pixels that a screen possesses which is expressed by the number of pixels on the horizontal axis times the number of pixels on the vertical axis. For example: 1280 x 720. The clarity of a display is defined by its resolution and its physical size. Pixel density is the measure for how good a display is by combining the above mentioned values.

What is pixel density?

Pixel density can be defined as the number of pixels per unit length. Usually it’s taken in terms of PPI, or Pixel Per Inch. Obviously, this defines the number of pixels in one inch of the display. It’s pretty simple, really: higher pixel density equals a better display. That’s all you need to know, aside from this…

The value of pixel density can be tweaked quite easily. All you need to do is reduce the size of the display. Theoretically speaking, you’ll have the same number of pixels crammed into a smaller space ...
