The ultraviolet absorbent absorbs short-wavelength blue light having a wavelength less than 400 nm and ultraviolet light emitting from a backlight module. The short-wavelength blue light and the ultraviolet light so absorbed excite the ultraviolet light emitting material to give off long-wavelength visible blue light having a wavelength greater than 400 nm. The first and second planarization layers are thus useful in converting ultraviolet light and short-wavelength blue light having a wavelength less than 400 nm, which could damage human eyes, into long-wavelength visible blue light having a wavelength greater than 400 nm that does not damage human eyes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for manufacturing eye-protecting liquid crystal display device","description":"A method for manufacturing an eye-protecting liquid crystal display device is disclosed, in which an ultraviolet light emitting material and a ultraviolet absorbent are added in a first planarization ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9671646","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.
