• Test pattern: in center,1/5(H)*1/5(V) of Window Pattern (white pattern in non-impressed condition)
• SET condition: Contrast &Brightness Level 100%
• Environment condition : Dark room in the non outside light
• Video menu option condition

5) Measurement
• Do heat-run LCD module at 30minutes in normal temperature (25°C)by using full white pattern of 15%signal level(38 gray level).
• Impress test pattern signal in 1/5(H)*1/5(V)White Window of 100%(255Gray Level)
• measure 3 times brightness of central white window,and mark peak brightness in max brightness degree
• measure the same condition in video signal /RGB 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 .
• 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
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
