The display panel includes a plurality of display blocks, and receives an image signal and display an image. The backlight unit includes a-numbered red light sources, b-numbered green light sources (a and b are natural numbers, b<a), and a-numbered blue light sources, and provides light to the display panel. The backlight controller calculates a red luminance average, a green luminance average, and a blue luminance average of the block image signals, respectively, controls a duty ratio of the red light sources based on the red and green luminance averages, controls a duty ratio of the green light sources based on the green luminance average, and controls a duty ratio of the blue light sources based on the blue and green luminance averages."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display device capable of reducing power consumption","description":"A display device including a display panel, a timing controller, a backlight unit, and a backlight controller.
