Notes 1. Contrast Ratio(CR) is defined mathematically as :
Surface Luminance with all white pixels
Surface Luminance with all black pixels
Contrast Ratio =
2. Surface luminance is luminance value at No.1 point across the LCD surface 50cm
from the surface with all pixels displaying white. For more information see FIG 2.
3. The variation in surface luminance , δ WHITE is defined as :
Minimum(Lon1 L, on2 ,….. Lon13
Maximum (Lon1, Lon2 ,.... Lon13
)
)
δWHITE
