Definition
minimum guaranteed value of the maximum obtainable ratio between the brightness of the light areas to the brightness of the dark areas of a liquid crystal display at specified values of the operating voltage, ambient temperature and viewing angle
Remark
The ratio is always a value greater than one. This means that, for a negative image mode, it is the ratio of the brightness of an addressed display zone to the brightness of a non-addressed zone and, for a positive image mode, it is the ratio of the brightness of the non-addressed zone to that of the addressed zone.
