5) Measurement
● Do heat-run LCD module at 5minutes in normal temperature (25 ) 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.
▣
Brightness / Contrast Tracking measure specification
1)
In non-impressed condition, measure peak brightness displayable as much as possible LCD module.
2)
Measuring instrument: CA-210 or a sort of Color Analyzer.
3)
Pattern Generator : VG-828 or a sort of digital pattern generator (displayable Full White)
4)
Measure condition
● Test pattern: in center, 1/5(H) * 1/5(V) of Window Pattern (white pattern in non-impressed condition)
● Environment condition : Dark room in the non outside light
