Note (1)
Definition of Viewing Angle (θx, θy):
Note (2) Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression and figure
below.
Contrast Ratio (CR) = L255 / L0
L255: Luminance of gray level 255
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).
