Have you played enough? How the pixel density race of screens went into oblivion

Many readers probably remember those times when almost no smartphone presentation was complete without

mention of display pixel density (ppi).It is generally accepted that it was started by Apple, which advertised the so-called Retina display in the iPhone 4, which was essentially a regular IPS panel with a pixel density of 326 ppi. His key idea was the inability to see individual pixels with the naked eye. Advanced Android competitors at that time (the first Samsung Galaxy S, for example) could offer at best 233 ppi, which made the iPhone 4 screen a breakthrough for its time.

In subsequent years, Android manufacturers quicklycaught up and even surpassed Apple by starting to release smartphones with QHD screens (Vivo Xplay 3S (490 ppi) in 2013, LG G3 (538 ppi) in 2014 and Galaxy S6 Edge (557 ppi) in 2016) and even 4K: Sony Xperia Z5 Premium (806 ppi) in 2015. And although such resolutions are often found in the most top-end devices today, it is often more a tribute to status than some kind of need: practice has shown that FHD+ screens are not only quite suitable for smartphones up to 6.7&# 8243;, but they also load the hardware less, thereby improving autonomy.

Moreover, more and more often in the device settings you cancome across an option that allows you to reduce the screen resolution from the original QHD + to economical FHD +, and since Android 13 it is built right into the system. In addition, there are much more important display parameters that have pushed the marketing PPI race into the background: high refresh rates, 10-bit colors, no PWM and no color distortion at low brightness. As for the pixel density, today it is enough for a smartphone to have an FHD screen in order to surpass the same Retina bar of 326 ppi.
