An initial set of drive instructions corresponding to a first frame causes the drive electronics to draw an initial pattern such as a solid red fill to selected regions of the display surface. An alternating set of drive instructions causes the drive electronics to draw a contrasting pattern such as a solid cyan fill to the selected regions. Given a sufficiently high refresh rate between the initial and alternating sets, a human operator perceives only the integration of the two patterns unless the display system is in a stuck or frozen state, when the frozen initial and contrasting patterns clearly and quickly indicate the stuck/frozen failure condition."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Passive and nonintrusive monitoring and reporting of frozen liquid crystal display (LCD)","description":"A passively and nonintrusively monitoring liquid crystal display (LCD) system includes a graphics controller configured to generate alternating sets of drive instructions and forward the drive instruc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10490111","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.
