(see figure 1 shown in appendix) lumi nance contrast ratio (cr) is defined mathematically. luminance when displaying a white raster cr = luminance when displaying a black raster 3. luminance of white is defined as a center point(#1) on lcd surface. luminance shall be measured with all pix els in the view field set first to white. this measurement shall be taken at the locations shown in figure 2 for a total of the measurements per display. 4. the white luminance uniformity on lcd surface is then expressed as : ?y = maximum luminance of 5 points / minimum luminance of 5 points (see figure 2 shown in appendix). 5. the color chromaticity coordinates specified in table 4 shall be calculated from the spectral data measured with all pixels first in red, green, blue and white. measurements shall be made at the center of the panel. 6. the electro - optical response time measurements shall be made as figure 3 shown in appendix by switching the ?data? input signal on and off. the times needed for the luminance to change from 10% to 90% is tr, and 90% to 10% is td. 7. cross - talk of one area of the lcd surface by another shall be measured by comparing the luminance (y a ) of a 25mm diameter area, with all display pixels set to a gray level, to the luminance (y b ) of that same area when a ny adjacent area is driven dark. (see figure 4 shown in appendix).
