How do I calculate PPI?
PPI (pixels per inch) = √(H² + V²) ÷ diagonal in inches. For example, an 800×480 panel on a 7.0-inch diagonal has a PPI of about 133.
No exact match for my resolution — what now?
RONEN offers 190+ standard modules and full ODM customisation. If no standard module matches your resolution and diagonal, our engineers can quote a custom panel — send your requirement through the free sample form or the contact page.
