The first level signal has a voltage polarity opposite to a voltage polarity of the second level signal. Therefore, it is ensured that any two adjacent sub-pixels have opposite voltage polarities when the short circuit between adjacent sub-pixels of the display panel is detected. The method also provides improved testing abilities to detect an open circuit in a sub-pixel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Circuit for testing display panel, method for testing display panel, and display panel","description":"A method for testing a display panel includes: applying a first level signal to a first sub-pixel and a third sub-pixel of a first pixel unit and applying a second level signal to a second sub-pixel o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9595215","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.
