10. 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 PDP module. 
2)  Measuring instrument: CA-210 or CS1000.  
3)  Pattern Generator : VG-828 or a sort of digital pattern generator    (displayable Full White & 1/100 White Window pattern) 
4)  Measure condition 
A.  Test pattern : in center, 1/10(H) * 1/10(V) of    Window Pattern (white pattern in non-impressed condition) 
B.  SET condition: Contrast Level => 100%, Brightness Level => Suitable Level (About 35~45). 
C.  Environment condition : Dark room in the non outside light   
5)  Measurement 
z 
Does heat-run PDP module at 30minutes in normal temperature (25℃) by using full white pattern of 15% signal level (38 gray level). 
z 
Impress test pattern signal in 1/10(H) * 1/10(V) White Window of 100%(255Gray Level) 
z 
Measure 3 times brightness of central white window, and mark peak brightness in max brightness degree   
z 
Measure the same condition in video signal /RGB signal. 
10.1.1  Average Brightness measure specification
