- 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-210 Dark room in the non outside light
3) Bright room measure condition: In bright room of 150Lx illumination in the panel surface, locate a source of light on the above
45º of the panel surface.
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
If it does not use Prior measurement, use generally simple test measurement. The Correct measure specification is followed
by IEC61988-2/CD,JAPAN EIAJ-2710
