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)
▣
Contrast ratio measure specification
1) Test display signal : 100%(255Gray)Full White Window signal & all Black Raster signal(0Gray)
2) Dark room measure condition : : Using touch type Color analyzer CA-210 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 100%(255Gray)Full White Window Pattern signal .
measure center peak brightness degree LV of white window
● Impress black Raster signal as contrast ratio measurement signal.
Measure black brightness degree Lb of central
Calculate the following numerical formula
Contrast ratio = LV / Lb
Contrast ratio = LV / Lb
If it does not use Prior measurement, use generally simple test measurement.
