Note 8. Light source here is the standard light source “C” which is defined by CIE and driving voltages are
based on suitable gamma voltages. The calculating method is as following :
A. Measure the “Module” and “BLU” optical spectrums (W, R, G, B)
B. Calculate cell spectrum from “Module” and “BLU” spectrums.
C. Calculate color chromaticity by using cell spectrum and the spectrum of standard light source
“C”.
Note 9. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are
determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which is
normal to the LCD surface. For more information see FIG4.
