Luminance when LCD is White
Luminance when LCD is Black
** 1. Topcon BM-7 (fast) luminance meter 2.0 field of view is used in the testing (after 20~30 minutes operation.)
2. Lamp Current: 6mA
3. Inverter model: TDK-347.
Luminance meter: BM-5A or MB-7 fast (TOPCON)
Measurement distance: 500mm +/- 50 mm
Ambient illumination: < 1 Lux
Measurement direction: Perpendicular to the surface of module.
The test pattern is white (Gray Level 63.)
*** The uniformity of LCD is defined as:
U=
The Minimum Brightness of the 9 testing Points
The Maximum Brightness of the 9 testing Points
