1. Contrast ratio

Contrast ratio (CR) is given by the following formula.

L(White): Surface illuminance of the screen at the input signal amplitude VAC = 0.5V

L(Black): Surface illuminance of the screen at VAC = 4.5V

Both luminances are measured by System I.

CR = L (White)

L (Black)

2. Luminous flux

In measurement system I, the average of the luminance at the nine points specified in ANSI standards when

the input signal amplitude VAC is 0.5V, multiplied by the effective display area, is computed.

L = average illuminance at nine ANSI points (lm/m2) × effective display area (m2)

3. Chromaticity

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. Color uniformity

In the measurement system I, the maximum values of the CIE color differences at the three points in the

middle row of the nine ANSI points, measured at an input signal amplitude VAC of 0.5V, are used to compute

the color uniformity.

∆Wx = x max – x min

∆Wy = y max – y min

For other electro-optical characteristics, refer to the LCX019AM specifications.
