2. Optical Transmittance
Optical Transmittance (T) is given by the following formula (2).
T = L (White)
×
100 (%) ... (2)
Luminance of Back Light
L (White) is the same expression as defined in the 'Contrast Ratio' section.
3. Chromaticity
Chromaticity of the panels are measured by System
I
. Raster modes of each color are defined by the
representations at the input signal amplitude conditions shown in the table below. System
I
uses
Chromaticity of x and y on the CIE standards here.

4. V – T Characteristics
V – T characteristics, the relationship between signal
amplitude and the transmittance of the panels, are
measured by System
II
. V90, V50 and V10 correspond
to the each voltage which defines 90%, 50% and 10%
of transmittance respectively.
5. Half Tone Color Reproduction Range
Half tone color reproduction range of the LCD panels is
characterized by the differences between the V – T
characteristics of R, G and B. The differences of these V – T
characteristics are measured by System
II
. System
II
defines signal voltages of each R, G, B raster modes
which correspond to 50% of transmittance, V
