An output current detection circuit generates a mirror current by copying the output current, and outputs an output current detection signal representing the mirror current. A failure determination circuit determines whether a failure is occurring or has occurred in the source line or not by comparing the level of the output current detection signal with a prescribed threshold value. The output current detection circuit includes a transistor that generates a mirror current by receiving the differential signal at a gate thereof, and a variable resistance that generates an output current detection signal upon receiving the generated mirror current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display driver and display device","description":"A display driver includes an amplifier circuit that outputs an output current based on a differential signal indicating a difference between a gradation voltage corresponding to a video signal and an ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11990069","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.
