Pixel density (ppi)
Pixels per inch — how sharp a screen looks. Above ~400 ppi, individual pixels are very hard to see at phone distance.
Pixel density (ppi, pixels per inch) combines screen size and resolution. A higher ppi means a sharper image. At normal phone viewing distance, differences above about 400 ppi are hard to notice.
Also called: pixels per inch, sharpness
