*Note (1) Definition of Contrast Ratio (CR):

The contrast ratio can be calculated by the following expression.

Contrast Ratio (CR) = L63 / L0.

L63: Luminance of gray level 63. L 0: Luminance of gray level 0. CR = CR (5).

CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note (5).
