Abstract: A light-emitting pixel structure is described that may include a group of light-emitting diode structures, where each of the light-emitting diode structures is operable to emit light characterized by a different peak emission wavelength. The structures may also include a patterned light absorption barrier characterized by a group of openings in the barrier, where each of the openings permit a transmission of a portion of the light from one of the light-emitting diode structures through the barrier. The structures may further include a metasurface layer operable to change a direction of at least some of the light transmitted through the openings of the patterned light absorption barrier from the light-emitting diode structures.
