1. Contrast Ratio
Contrast Ratio (CR) is given by the following formula (1).
CR = L (White)... (1)
L (Black)
L (White): Surface luminance of the center of the screen at the input signal amplitude V
AC
= 0.5V.
L (Black): Surface luminance of the center of the screen at V
AC
= 5.0V.
Both luminosities are measured by System
