The position of measuring area corner: X=10.0mm ; Y=10.0mm
Luminance of center point: L=L(1)
Brightness Uniformity Measurement points: Five specified points 1-5
Formula: Maximum [L (1), L (2), L (3), L (4), L (5), L (6), L (7), L (8), L (9), L (10), L (11),
L (12), L (13)]/Minimum [L (1), L (2), L (3), L (4), L (5), L (6), L (7), L (8), L (9), L (10), L (11),
