• Manufacturer Part Number: M201P1-L03
• Description: LCD Module
• Manufacturer: CHI MEI

Note (4) Definition of Luminance of White (L
Note (5) Measurement Setup:
Note (6) Definition of White Variation (δW):
temperature change during measuring. In order to stabilize the luminance, the measurement
should be executed after lighting Backlight for 20 minutes in a windless room.
Measure the luminance of gray level 255 at 13 points
δW = Maximum [L (1), L (2) ……L (12), L (13)] / Minimum [L (1), L (2) …… L (12), L (13)]
The LCD module should be stabilized at given temperature for 20 minutes to avoid abrupt
