Viewing angle range is measured by System I.
The contrast ratio (CR) is measured at the
angles defined in the figure to the right and the
range where CR ≥ 10 is taken as the viewing
angle range.
Measure with surface A facing upwards.
Surface reflection ratio (Rf) is given by the following formula.
Rf = Reflected optical luminance of the panel surface A /Reflected optical luminance of Al (wafer)
The incident and reflected angles of light are both 0°.
Both luminosities are measured by System III.
Cross talk is determined by the luminance differences between adjacent areas represented by Wi' and Wi
(i = 1 to 4) around the black window (Vsig = 4.0V/1V).
