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.

CR = L (White)/L (Black)

2. Luminous intensity

In Measurement System I, the average of the illuminance at the nine points specified in the ANSI standards

when the input signal amplitude VAC is 0.5V, multiplied by the projection area, is computed.

Nine ANSI points: centers of each of the

areas obtained by dividing

the effective display area

into nine smaller areas

3. Chromaticity

Raster modes of each color are defined by the representations at the input signal amplitude conditions shown

in the table below. Measurement System I uses chromaticity of x and y of the CIE standards here.

4. Color shading

In Measurement System I, the maximum values of 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

shading.
