The first optical sensor has a function of detecting illuminance of external light, and the second optical sensor has a function of detecting a color tone of polarized light emitted from the pixel portion. The lightning portion can emits light having a predetermined wavelength depending on the color tone of the pixel portion which is detected by the second optical sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid crystal display device having optical sensor","description":"A liquid crystal display device which includes a pair of substrates, a pixel including a liquid crystal element between the pair of substrates, a lighting portion provided on the outer side of the pai","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9720277","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.
