The display is the most important part of a smartphone. It is the unit which makes the smartphone appealing to the users as well as show off the power of the phone. We have come out from an era of very low quality displays to one with resolutions to match the human eye.
Initially, the iPhone’s Retina display made people wow at the displays, their sharpness, colour reproduction and awesome levels of saturation and contrast. But as the smartphones have evolved, so have their displays making the screens their very own lineup at each generation.
The smartphones of the past contained displays with qualities ranging from 480p (480 x 800 pixels) which were known as the WVGA lineup of displays. Many of the superphones of the past sported these displays and boosted these screens.
A slight boost in resolution from this generation led to the FWVGA line of displays which had a resolution of 480 x 854 pixels.
The next generation of displays in smartphones was the qHD lineup. These displays had a boosted resolution of 540p (540 x 960) which made the display sharper and much more vivid.
Now was a time for the ‘Next Big Thing’ in display tech, the first HD screens were released with such high pixels per inch that the Retina Displays were the things of the past. The 720p (720 x 1280) displays have been used in many of the latest smartphones making these phones display very sharp images which are practically impossible to be discernable by the human retina.
But as with everything else, we humans love to boast. Even though the 720p displays are too high a resolution to be noticed, we wanted more. So, manufacturers worked more and got us the next generation of HD displays, the 1080p (1920 x 1080) lineup of displays. These screens are practically too sharp to even differentiate between the pixels of the displays, with pixel densities skyrocketing and surpassing 400 ppi easily, that is like having a single almost 320p display per inch of the screen.
No, we wouldn’t stop yet. So the advent of the ‘K’ lineup of displays was started and is still under works. The 2K display was debuted by the LG G3, making the phone one of the best last year. Now we are waiting for the 3K and 4K displays with the flagships of this year. Hopefully they will blow our mind off.
If we continue display development at this rate, at some point of time, we will have nano or even pico pixels or maybe even NO pixels at all.
