This driving method includes: controlling an organic light-emitting diode of the LED display by an emission signal having a plurality of frame periods, with each of the frame periods having a PWM part with a duty ratio; detecting whether a change in the refresh rate of the LED display exists; and performing a compensation procedure when the change is detected, with the compensation procedure compensating a brightness difference of the organic light-emitting diode occurring due to the change in the refresh rate by adjusting the duty ratio of the PWM part. Said LED display is also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light emitting diode display and driving method thereof for reducing brightness change due to refresh rate variation","description":"A driving method of LED display, configured to be applied to an LED display capable of varying a refresh rate thereof and able to reduce brightness changes due to refresh rate variation, is disclosed ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11508305","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.
