Peak & average Brightness & Contrast measure standard specification
- White Peak brightness measure specification
1) In non-impressed condition, measure peak brightness displayable as much as possible LCD module.
2) Measuring instrument: CA-110 or a sort of Color Analyzer. 
3) Pattern Generator : VG-828 or a sort of digital pattern generator (displayable Full White & 1/25 White Window pattern)
4) Measure condition
-  Test pattern: in center, 1/5(H)x1/5(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)x1/5(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.
Average Brightness measure specification
1) Impress 100%(255Gray Level) full white pattern at the same peak brightness measurement.
2) Measure average brightness in 9 points. 
Contrast ratio measure specification
1) Test display signal : 30x30 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) Bright room measure condition :  In bright room of 150Lx illumination in the panel surface, locate a source of light on the above
45°of the panel surface.
4) Measure method
- In standard test condition, impress 30x30 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
