Patent ID: 8471250

Claim:
A display apparatus, comprising: an organic electroluminescence device, for emitting a light, wherein a curve of a relationship between the wavelength and the light intensity of the light has a peak in a band of 420 nm to 480 nm, a band of 480 nm to 540 nm, and a band of 590 nm to 650 nm respectively; and a color filter, for receiving and converting the light into a color light, wherein a correlated color temperature (CCT) of a white screen displayed by the display apparatus is in the range of 8000K to 12000K, and a curve of a relationship between the wavelength and the light intensity of the white screen has a first peak in a band of 420 nm to 480 nm, a second peak in a band of 480 nm to 540 nm, and a third peak in a band of 590 nm to 650 nm respectively, and a ratio of the second peak to the first peak is in the range of 0.31 to 0.40.
