The image display apparatus further includes a counter electrode voltage control module that generates a counter electrode voltage to be input into the liquid crystal panel and supplies the generated counter electrode voltage to the liquid crystal panel. The counter electrode voltage control module has: a counter electrode voltage setting module that sets a counter electrode voltage control level corresponding to the light control level; and a counter electrode voltage generation module that generates the counter electrode voltage in response to the set counter electrode voltage control level. This arrangement enables dynamic adjustment of the counter electrode voltage of the liquid crystal panel in response to a dynamic change in amount of the illumination light for irradiating the liquid crystal panel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic adjustment of counter electrode voltage of liquid crystal panel according to illumination light control","description":"The image display apparatus of the invention has: a liquid crystal panel that is used to display an image represented by input image data; and a lighting device that emits illumination light controlle","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8514156","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.
