All about your Smartphone’s Screen resolution and Pixel density (DPI)

Smartphone Screen resolution

We might be seeing some 1280 x 720 pixels (HD) or 960 x 540 pixels (qHD) or most likely 1920 x 1080 pixels(Full HD)as your screen resolution while buying your smartphone. What Smartphone Screen resolution actually mean, is our topic for today. While Screen resolution is not a topic limited to smartphones, but here we consider them as favorites as we use them more often. Every digital device like a television, monitor and so on…Every displaying screen has a Screen resolution and Pixel density. Starting with Smartphone’s Screen resolution we will move forward into Pixel density and their importance.

Smartphone’s Screen Resolution and Pixel Density:

The Smartphone screen resolution represents the number of distinct pixels displayed in the each dimension of the display. Pixel density is the ratio of screen resolution to display size and represent the number pixel per inch of the display. It varies accordingly with resolution and size of the display. The diagonal length of the screen is considered as display size. If you consider a 5-inch 720p display it will have pixel density around 293 pixels. Similarly, 5.5 inch 1080p will give you around 341 pixels per inch. Anything around 300 pixels is regarded as good pixel density as it is what our human eyes can distinguish. While Screen resolutions on devices can be lowered, they can be extended beyond the display hardware. Users can check the Screen resolution of their display using this link.

While Screen resolutions on devices can be lowered, they can be extended beyond the display hardware. Suppose you have a smartphone with a 1080p screen, we can lower its resolution to 720p using software tweaks but it can’t be increased beyond 1080p, the default capacity. In the case of watching multimedia, we can play a 1080p video on a device with a 720p screen, but what you only see on your screen is the 720p version of that video. In the vice versa case, if we play a 720p video on a 1080p device, Again what we get is a 720p video quality, but here the quality is limited by the video not by the screen as in above case. These examples apply universally to any digital device.

The importance of Smartphone’s Screen Resolution and Pixel Density:

Hardware may be important but the display is equally important concerning comfort of our eyes and looks of the smartphone. And yes, certain displays can also change the look and feel of your phone. For example, consider Curved displays and the new infinity/Univision displays with 2:1 aspect ratio, the beauty they add to our smartphone is really beautiful. May not be the first preference, but screen resolution and Pixel density have their own importance, especially if you consume a lot of multimedia content on your smartphone.

Anything less than 720p (HD) is barely acceptable nowadays, not even in the entry-level segment. Then the 1080p Full HD is good enough for your entertainment needs on smartphone screens. Yet, 2K displays are not very common, unless for a Flagship smartphones. 2K screens are also not distinguishable expect while using a VR headset. So, a 2K screen is not a deal breaker unless users watch a lot of VR content. While 4K and 8K screens are not far from reality, they need more time and reasons to reflect. They are more common on larger display devices like smart TVs, Monitors, and Projectors. In fact, Sony already released few Android phones with a 4K display, but display alone can’t win the game.
