The driving controller is further configured to compare a source voltage of each of the light transistors with an overcurrent protection voltage and to turn off an operation of a corresponding light transistor having a source voltage level higher than the overcurrent protection voltage. The backlight unit further includes a first comparator configured to compare the source voltage of the corresponding light transistor with a reference source voltage to output a feedback voltage according to the compared result; and a first switch configured to electrically connect the first comparator to a gate terminal of the corresponding light transistor, wherein the first switch operates in response to an overcurrent protection signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Backlight unit and display device including backlight unit with overcurrent protection","description":"According to an exemplary embodiment, a backlight unit includes a plurality of light emitting strings, and a driving controller configured to detect source voltages of a plurality of light transistors","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9668316","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.
