Page "Liquid crystal display" Paragraph 71

The spatial resolution of an LCD is expressed by the number of columns and rows of pixels ( e. g., 1024 × 768 ).

Each pixel is usually composed 3 sub-pixels, a red, a green, and a blue one.

This had been one of the few features of LCD performance that was easily understood and not subject to interpretation.

However there are newer schemes that share sub-pixels among pixels and to add additional colors of sub-pixels.

So going forward, spatial resolution may now be more subject to interpretation.
