7.3 Peak & average Brightness & Contrast measure standard specification
7.3.1 White Peak brightness measure specification
1) In non-impressed condition, measure peak brightness displayable as much as possible PDP module.
2) Measuring instrument: CS-1000, CA-210, CA-100+ or a sort of Color Analyzer.
(Please adjust CA-210, CA-100+ by CS-1000 before measuring.)
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
a. Do heat-run PDP module at 30minutes in normal temperature (25
℃
) by using full white pattern
of 15% signal level (38 gray level).
b. Impress test pattern signal in 1/10(H) * 1/10(V) White Window of 100% (255Gray Level).
c.
Measure 3 times brightness of central white window, and mark peak brightness in max
brightness degree.
d. Measure the same condition in video signal /RGB signal.
7.3.2 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.
