The color gamut controlling device includes a light sensing unit, a first calculation unit, a second calculation unit, and a color gamut calculation unit. The light sensing unit measures a luminance of external light. The first calculation unit calculates adjusted tristimulus values for each of three primary colors based on the measured luminance. The second calculation unit calculates final tristimulus values for each of the three primary colors using the adjusted tristimulus values and target tristimulus values for each of the three primary colors. The color gamut calculation unit calculates a corrected color gamut from the final tristimulus values. The light sensing unit may further measure tristimulus values of the external light for each of the three primary colors."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device for controlling color gamut and display device including the same","description":"A color gamut controlling device and a display device including the color gamut controlling device.
