NetCast 4.0 Low – LC36B Product Specification
▣
Luminance uniformity measure Condition
1)
Impress 100 % (255Gray Level) full white pattern at the same peak brightness measurement.
2)
Measure brightness L0~L8 in each 9 points P0~P8
- Luminance uniformity(%) = Minimum(L1, L2, L3, …, L8) / Maximum(L1, L2, L3, …, L8) * 100
- Average Luminance = Sum of Luminance(L1, L2, L3, …, L8) / 9
▣
Contrast ratio measure specification
1)
Test display signal : 30*30 dots White Window signal & all Black Raster signal
2)
Dark room measure condition : : Using touch type Color analyzer CA-100 Dark room in the non outside light
3)

4)
Measure method
● In standard test condition, impress 30*30 dots White Window Pattern signal. Measure center peak brightness degree Lw of white window
● Impress black Raster signal as contrast ratio measurement signal. Measure black brightness degree Lb of PDP central. Calculate the following numerical formula.
Contrast ratio = Lw / Lb
5) Video menu option condition
