Abstract

A device includes a three-dimensionally curved substrate, a patterned metal layer disposed on the curved substrate, and an array of optoelectronic devices, each optoelectronic device including an optoelectronic structure supported by the curved substrate. Each optoelectronic structure includes an inorganic semiconductor stack. The device further includes a set of contact stripes extending across the curved substrate, each optoelectronic structure being coupled to a respective contact stripe of the set of contact stripes. The array of optoelectronic devices is secured to the curved substrate via a bond between the patterned metal layer and the set of contact stripes.
