Regardless of the device you use, display is the most important part of a device.By the invent of touch screens the display has become a two way interaction surface.Thus to be dealt with the most important part of the smartphone or your desktop,it is vital for it to be more and more user friendly and biocompatible.
The factor which determine the quality of display is resolution.To be more precise Pixels Per Inch ( PPI ).It is the actual number of pixels that can show color at each square inch of the display.From the past we have been getting improved display with increasing PPI values.from the old 256 k color 140p displays with mere 140 PPI towards 8 k displays.In the past no one cared for the PPI value of the screen.but with the advent of newer techs in smartphones, the supply of better displays have been made.Gradually we are also made to like those insanely high PPI Displays.The range is now at whopping 577 PPI with the release of Samsung galaxy S6 which packs a 4k AMOLED panel over the 5.2 inch display.
But the question is ,how much PPI can human eyes actually recognize with his naked eye? It depends upon the viewing distance.That is the distance between our eyes and the display surface.The normal viewing distance for healthy viewing is 12 inches.For that distance,the utmost number of PPI a human can see is around 300 PPI.The more closer you go near the display, more the pixel will appear.But is there any benefits with smartphones with 577 PPI? The answer is Yes! A human eye can see no pixels at 12 inches distance,but can spot pixels as he moves closer below 12 inches.But how far? The minimum focal length of a human eye is about 4 inches.We cant focus on anything closer than 4 inches from our eyes.So there is a breaking point for this PPI war. Which at 4 inches, when calculated the PPI with no pixelation at this point is 876 PPI. Which is for a human with 20/20 score in eyesight.So that is the breaking point for this PPI war by smartphone manufacturers.But why should we look at a smartphone display from that breaking point distance?Is it a marketing gimmick? No,the next era of smartphone is virtual reality which already is in existence like google cardboards for smartphones.This requires viewing distance of almost close to 4 inches and it is required for better immersive VR experience.Now you know that smartphones manufacturers are determined and aimed for the future than mere marketing gimmicks.
But can these increasing PPI rates be useful to the human eyes?do they reduce eye strain? The answer is YES.It has been scientifically proven that increasing PPI's reduces eye strain.As low pixel rate will make human eyes strain to recognize and connect pixels into a picture or alphabet (although it is involuntary).This has been proved long before since smartphones are invented.Lets take the case of magazines.The magazines are printed in 300 PPI. magazines are recommended to be read from a distance of 12 inches from it's surface.Thus we wont be able to notice any pixelation. This reduces eye strain.Smartphones with much higher PPI rates can be viewed closer and we wont notice any pixels at all and thereby low strain as compared to low PPI displays.Lets find out what the next step of display tech be, after reaching the breaking point in time frame.
