Abstract

A display includes a plurality of pixel chips, chixels, provided on a substrate. The chixels and the light emitters thereon may be shaped, sized and arranged to minimize chixel, pixel, and sub-pixel gaps and to provide a seamless look between adjacent display modules. The substrate may include light manipulators, such as filters, light converters and the like to manipulate the light emitted from light emitters of the chixels. The light manipulators may be arranged to minimize chixel gaps between adjacent chixels.
