Product Specification
LC370WX1
Liquid Crystal Display
Notes 1. Contrast Ratio(CR) is defined mathematically as :
Surface Luminance with all white pixels
Contrast Ratio =
Surface Luminance with all black pixels
It is measured at the center point(1).
CR
D
is measured when Dynamic CR is enabled.
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
on1
,L
on2
, L
on3
, ...... , L
on5
) / Minimum(L
on1
,L
on2
, L
on3
, ..... , L
on5
)
Where L
on1
to L
on5
are the luminance with all pixels displaying white at 5 locations .
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
R
)
and from G(M) to G(N) (Decay Time, Tr
D
). For additional information see the FIG. 3. (N<M)
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.
