1. A light-emitting subpixel structure comprising:
a directional light-emitting diode structure characterized by a full-width-half-maximum (FWHM) of emitted light having a divergence angle of less than or about 10′;
a lens positioned a first distance from the light-emitting diode structure, wherein the lens is shaped to focus the emitted light from the light-emitting diode structure; and
a patterned light absorption barrier positioned a second distance from the lens, wherein the patterned light absorption barrier defines an opening in the barrier, and wherein a focal point of the light focused by the lens is positioned within the opening.
