The backlight controller causes the key backlights to emit light of a first color in a case where an input key out of the input keys detects pressing thereon, and changes an emission color of a key backlight corresponding to the input key detecting the pressing from the first color to a second color when a state of the pressing becomes a predetermined state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Terminal apparatus, backlight emission method and computer readable medium for terminal apparatus","description":"The terminal apparatus includes input keys configured to detect pressing conducted thereon respectively, key backlights each of which emits a plurality of colors of light to shine corresponding one of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8487878","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.
