A plurality of electrodes (14, 16) are provided, at least two of which contact said portion of material (10). A controller (19) is provided that is adapted to apply at least one voltage to said material (10), via said electrodes (14, 16), to change said refractive index. An array of such portions of material can be arranged to make a pixellated display, for example a stereoscopic display of the volumetric type."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display device based on phase-change materials","description":"A display device comprises a plurality of pixels, each pixel having a portion (10) of a solid-state, phase-change material such as germanium-antimonium-telluride (GST) or vanadium dioxide, wherein the","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9823538","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
