What is display PPI/DPI? #17

Closed ghost closed 4 years ago

Can you specify what is resolution of display and its PPI/DPI?

As I can see on photos its PPI is very low (bold pixels)

The resolution is 400x300 at 120 dpi, which is low for displaying graphics, but workable for reading text. It's a tradeoff: higher-resolution screens are more expensive, and I'm trying to keep the BOM cost as low as possible. This page has specifications for the panel if you're interested in learning more.

Thanks for the feedback!
