Notes 1. Contrast Ratio(CR) is defined mathematically as :
Contrast Ratio =
It is measured at the center point(1).
CR
is measured when Dynamic CR is enabled.
D
2. Surface luminance is luminance value at the center point across the LCD surface 50cm from the
surface with all pixels displaying white.
For more information, see FIG 2.
3. The variation in surface luminance , δ WHITE is defined as :
δ WHITE(5P) = Maximum(L
Where L

For more information, see FIG 2.
4. Response time is the time required for the display to transition from G(N) to G(M) (Rise Time, Tr
and from G(M) to G(N) (Decay Time, Tr
5. 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 FIG 4.
6. Gray scale specification
Gamma Value is approximately 2.2.
For more information, see Table 12.
7. Black Level and Black Uniformity :
This is only for the reference. Please refer to attached Appendix A for the details.
