Display Resolution Explained

Display Resolution
All must have heard about 720p, 1080p, 2K when we see the configuration of the displays. So today in this article we are going to discuss about resolution of displays. So what does it mean by 720p display or 1080p display. This actually tells us the resolution of the displays.
The 720p means that this display has a resolution of 1280*720. It means that the screen is having 1280 pixels in the horizontal and 720 pixels in the vertical side. And now you must be wandering what does it mean by pixel? The pixel is the smallest unit of the picture on the display just like cell which is the basic unit of our body.
So more the pixels, better will be the picture quality. The 1080p display has a resolution of 1920*1080 pixels which means that 1920 pixels on the horizontal side and 1080 pixels on the vertical side. So clearly 1080p display will have much better picture quality as it is having more pixels on the same screen.
Also you must have heard the word PPI which stands for pixel per inch, that means number of pixels available per inch on the display. We can also consider PPI to be pixel density. So 720p displays have less ppi than that of 1080p displays. That's why 1080p displays are better than 720p displays.
We also hear the term aspect ratio, but what does this mean? Aspect ratio is just the ratio of the pixels on the horizontal and vertical side of the display. For example aspect ratio of 720p displays will be the ratio of 1280:720 which actually equals to 16:9. But generally we use term 16:9 instead of 1280:720.
 These days smartphone brands are preferring the new aspect ratio for their smartphones that is 18:9 which actually increase the pixel count on the screen thus making the bezels smaller. Many of the flagship phones like Samsung Galaxy Note 7, Google Pixel XL, Apple iPhone X have this kind of display.
