The display panel emits a green light having a green energy and a green point of the CIE 1931 xy chromaticity under the operation of the highest gray level of a green image, and emits a blue light having a blue energy and a blue point of the CIE 1931 xy chromaticity under the operation of the highest gray level of a blue image. The ratio of the green energy to the blue energy is between 0.7 and 1.5, and the coordinates of the green point in the CIE 1931 xy chromaticity diagram are bounded by the equation: y=−48.85x2+21.987x−1.7766 and the equation: y=−48.85x2+27.849x−3.2717, while y is between 0.68 and 0.72."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display apparatus","description":"A display apparatus comprises a display panel.
