New Vivo phone has a 538 ppi display — but is it really necessary?
A new smartphone from Chinese manufacturer Vivo boasts a 538 ppi display. The Vivo Xplay 3S has a 5.5-inch, 2,560 x 1,440 resolution screen, making it the first smartphone with a 2K HD display powered by a Snapdragon 800 processor.
Whether it is creating the thinnest, lightest or biggest device, smartphone manufacturers are constantly clamoring to hold the top title in some category. But is Vivo's super high resolution 538 ppi smartphone display unnecessary?
When Apple announced it Retina Display in 2010, it proudly boasted that it had reached display technology's limit. According to Apple's research, the human eye cannot see more than 300 ppi when a device is within 10 to 12 inches from it. At the time, other researchers refuted Apple's claims, saying that if your hold your phone at 12 inches from your eye, you need to have a pixel density of 477 ppi — 716 ppi if you hold it just four inches closer.
While Apple's iPhone displays have stayed at a steady 326 ppi since the iPhone 4S, other manufacturers are raising the bar. Samsung's Galaxy S4, the HTC One and Sony Xperia Z all have displays with over 400 ppi. With 538 ppi, the Vivo Xplay 3S goes far beyond.
Have we reached the end of the display race? Will other manufacturers will continue to pack more pixels into their displays, or will they admit to reaching the limit set by the human eye?
