Extended Data Fig. 2: Arbitrarily selected combinations of RGB pixels.
From: Video‐rate tunable colour electronic paper with human resolution
The intermediate regions of RGB pixels contain only cyan and yellow, with no magenta. By optimizing subpixel spacing (T), a yellow pixel appears when the red-green subpixel distance is 240 nm, while a cyan pixel emerges at a blue-green subpixel distance of 120 nm. However, regardless of the red-blue subpixel distance, magenta cannot be produced, highlighting a fundamental limitation in colour.
