2. Optical Transmittance

Optical Transmittance (T) is given by the following formula (2).

T =

x 100 [%] ...(2)

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

the each voltage which defines 90%, 50% and 10% of

0.5V is 100%.)

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

simply given by the following formulas (3) and (4)

respectively.
