Display apparatus and manufacturing method thereof
View Patent ↗A display apparatus comprises a display panel. 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 1.2. In the CIE 1931 chromaticity diagram, the coordinates of the blue point are bounded by the equation: y=−168.72x 2 +50.312x−3.635 and the equation: y=−168.72x 2 +63.81x−5.9174, while y is between 0.04 and 0.08.
