A NIT is a measurement of light in candelas per meter squared (Cd/m2). The unit is based on the
candela, the SI unit of luminous intensity, and represents a measure of light emitted per unit area.
This is a common metric used in characterizing the brightness of a display device. This can apply
to either the LCD display module as a whole assembly, or a measurement of the backlighting
system alone without the LCD glass.
