Luminance means a measure of the brightness of a luminous surface.
Luminance contrast means the brightness ratio between an object and its immediate background/surrounding that allows the object to be distinguished from its background/surroundings.
Luminance means the photometric measure of the luminous intensity per unit area of light traveling in a given direction, expressed in units of candelas per square meter (cd/m2). The term brightness is often used to ‘subjectively’ qualify the luminance of a display;

More Definitions of Luminance
Luminance means the amount of light that passes through or is emitted from a particular area and falls
Luminance means an objective measurement of the brightness of illumination, including illumination emitted by an electronic sign, measured in candles per square foot (cd/ft2).
Luminance means the light that is emitted by or reflected from a surface, measured in units of luminous intensity (candelas) per unit area (square meters in SI measurement units or square feet in English measurement units).
Luminance means the photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through or is emitted from a particular area, and falls within a given solid angle. The unit for luminance is candela per square meter (cd/m2), also known as “nit”.
Luminance means the physical measure of the stimulus, which produces the sensation of brightness.7
Luminance means the amount of light that emanates from an internally illuminated sign. This parameter is measured in nits (candelas/square meter). The nit levels necessary for a sign to be legible varies with the ambient light conditions. For example, on a sunny day, the nit levels must be very high, while at night, the nit levels must be very low to prevent the image from distorting and to prevent glare.
Luminance means the amount of light that passes through or is emitted from a particular area and falls within a given solid angle.
