The gamma voltage generator generates first and second reference voltages, generates first and second corrected reference voltages by correcting the first and second reference voltages using a target voltage and an external power voltage provided from the display unit in correspondence with the first power voltage, and generates the gamma voltages by dividing the first and second corrected reference voltages. The gamma voltage generator sets the target voltage based on at least one selected from the first reference voltage, the second reference voltage, and a ground voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gamma voltage generation circuit and display device including the same","description":"A display device includes a display unit including a pixel which displays an image based on a first power voltage and a data signal, a gamma voltage generator which generates gamma voltages, and a dat","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11462146","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.
