The driving sequence is divided into the display stage and the touch-sense stage, and the touch sensing and positioning of touch point is accomplished by VDD signal lines, such that no any change is made to any process or profile of the pixel structure in the touch-sense stage, reducing the thickness and manufacturing cost of the display device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for driving AMOLED-based touch display panel","description":"A method for driving an AMOLED-based touch display panel, comprising: when driving the AMOLED to display, dividing one cycle of driving sequence into a display stage and a touch-sense stage; in the di","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9666122","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.
