5) Measurement
• Do heat-run LCD module at 5minutes in normal temperature (25°C) 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.
• 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.
6.1.3 Luminance uniformity measure specification
1) Impress 100 % (255Gray Level) full white pattern at the same peak brightness measurement.
2) Measure average brightness in 9 points.
2) Measure average brightness in 9 points.
6.1.4 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-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
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 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
Calculate the following numerical formula.
Contrast ratio = Lw / Lb
* If it does not use Prior measurement, use generally simple test measurement. The Correct measure specification is followed by
