9. Definition of Viewing Angle Range
Viewing angle range is measured by System Ι. 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.

10. Surface Reflection Ratio
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) × 100 [%]
The incident and reflected angles of light are both 0°.
Both luminosities are measured by System III.
Surface A: See the Package Outline.
11. Cross Talk
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).
