The emitter array emits from its emission surface output light that is transmitted through the substrate, and enables selective activation of and emission from individual elements or subsets of elements of the array. The structured lens is formed on or in the substrate, and comprises micro- or nano-structured elements resulting in an effective focal length less than an effective distance between the structured lens and the emission surface. The angular filter is positioned on or in the substrate or on the emission surface and exhibits decreasing transmission or a cutoff angle with increasing angle of incidence."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light-emitting device assembly with emitter array, micro- or nano-structured lens, and angular filter","description":"A light-emitting device assembly includes an emitter array of light-emitting elements, a transparent substrate, a structured lens, and an angular filter.
