Abstract
Generic optical matrices may have pixels corresponding to color and sub-pixels corresponding to non-color effects. A generic optical matrix may include an array of pixels disposed on a substrate. The array may comprise first pixels corresponding to a first color and second pixels corresponding to a second color. The first and second pixels may be arranged in a motif such that individual ones of the first pixels are positioned adjacent to individual ones of the second pixels. Individual ones of the pixels may comprise sub-pixels. A given pixel may comprise a first and a second sub-pixel. The first sub-pixel may comprise an optical structure configured to reflect or transmit light meeting a first condition. The second sub-pixel may comprise an optical structure configured to reflect or transmit light meeting a second condition. The light reflected or transmitted by the sub-pixels may be the corresponding color of the given pixel.
