In the display stage, the display control circuit outputs a first common voltage, and the synchronization control circuit controls the switch control circuit to output a second common voltage equal to the first common voltage. Many advantages are provided, such as a uniform display effect, fewer residual ions, better display quality, higher reliability, simplified circuit, lower cost, and increased light transmittance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch control display screen and electronic device","description":"A touch control display screen includes: a touch control electrode layer including a plurality of touch control electrodes; a first electrode layer opposite to the touch control electrode layer and in","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9798402","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.
