(1)Definition of Viewing Angle (θx, θy):
12 o’clock direction
θy+ = 90º
6 o’clock
θy-= 90º
θx-θx+
θy-θy+
x-y+
y-x+
Normal
θx = θy = 0º
θX+ = 90º
θX-= 90º

(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).
Definition of luminance measured points and Brightness Uniformity:
Luminance of center point: L=L(5)
Brightness Uniformity Measurement points: Five specified points 1-5
Formula: Maximum [L (1), L (2), L (3), L (4), L (5)]/Minimum [L (1), L (2), L (3), L (4),
L (5)]
