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 & 1/25 White Window pattern)
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
● Video menu option condition : Shipment MODE.(In-Stop)

▣
Luminance uniformity measure Condition
1) Impress 100 % (255Gray Level) full white pattern at the same peak brightness measurement.
2) Measure brightness L0~L8 in each 9 points P0~P8
- Luminance uniformity(%) = Minimum(L1, L2, L3, …, L8) / Maximum(L1, L2, L3, …, L8) * 100
- Average Luminance = Sum of Luminance(L1, L2, L3, …, L8) / 9
▣
Contrast ratio measure specification
1) Test display signal : 30*30 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 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
