Claim 4:
5. The method for calculating the chromaticity value of the white screen of the display device of claim 1, wherein the test transmittance spectrum value of the white screen of the display panel of the test display device is calculated by dividing a sum of the initial spectrum value of the first sub-pixel multiplied by the relative variation of the test aperture ratio of the first sub-pixel relative to the initial aperture ratio of the first sub-pixel, the initial spectrum value of the second sub-pixel multiplied by the relative variation of the test aperture ratio of the second sub-pixel relative to the initial aperture ratio of the second sub-pixel, and the initial spectrum value of the third sub-pixel multiplied by the relative variation of the test aperture ratio of the third sub-pixel relative to the initial aperture ratio of the third sub-pixel, by the initial spectrum value of the backlight source.
