Abstract

A pixelated display device and a method for making the same are disclosed. The device may include an array of nanowire LEDs located above a substrate. When the nanowire LEDs are initially grown, they may emit first-wavelength light proximally to the substrate and second-wavelength light distally from the substrate. The nanowires may remain as initially grown, in which case only second-wavelength light is visible, or the second-wavelength light emitting portions may be etched away such that only first-wavelength light is visible.
