Viewing angle is the angle at which the contrast ratio is greater than 10. The viewing are
determined for the horizontal or 3, 9 o’clock direction and the vertical or 6, 12 o’clock direction
with respect to the optical axis which is normal to the LCD surface (See FIGURE 1 shown in
Appendix).
Contrast measurements shall be made at viewing angle of = 0 and at the center of the LCD
surface. Luminance shall be measured with all pixels in the view field set first to white, then to
the dark (black) state. (See FIGURE 1 shown in Appendix) Luminance Contrast Ratio (CR) is
defined mathematically.
Center Luminance of white is defined as the LCD surface. Luminance shall be measured with
all pixels 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.
The White luminance uniformity on LCD surface is then expressed as : ΔY = Maximum
Luminance of five points / Minimum Luminance of five points (See FIGURE 2 shown in
Appendix).
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.
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 Td, and 90% to 10% is Tr.
Cross-Talk of one area of the LCD surface by another shall be measured by comparing the
luminance (Y
