Here is a comprehensive guide to understanding, calculating, and applying these conversions using the latest digital imaging standards. Why Pixel-to- mm2mm squared Conversion Matters

Using this metric, the new nano‑pixel display achieves approximately (since a 1920 × 1080 display contains roughly 2.07 million pixels, and those pixels fit within 1 mm²). This is an order of magnitude beyond what was previously possible.
