108.8 PPI - Low density (LDPI)

  • At 108.8 PPI this screen falls in the "Low density (LDPI)" density tier.
  • Each pixel is about 0.233 mm wide. Below roughly 0.05 mm (over 500 PPI) individual pixels become invisible to the naked eye at a normal viewing distance.
  • The panel holds 3.69 million pixels in total, arranged in a 16:9 aspect ratio.

Next stepBelow 200 PPI is typical for large desktop monitors viewed from 60+ cm. Pixels become more visible at closer distances.
