When a duty ratio is changed from a pre-modified duty ratio (Ds) to a post-modified duty ratio (Df) over a color modification time (Td) from the start to the end of a color modification, the modified duty ratio (Dn) is determined through a calculation using equation for a fade-in process and equation for a fade-out process. Determining the modified duty ratio (Dn) in this manner can modify colors smoothly while reducing emergence of any unnatural colors."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Color control method","description":"Provided is a color control method that allows for a smooth modification of various display colors without using a huge number of parameters.
