Luminance: Luminous intensity reflected or emitted by a surface in a given direction per unit of apparent area.
Measured in nits.
Lumen: The unit of luminous flux or rate of luminous energy flow. It is equal to the flux radiating through a unit
solid angle (steradian) from a uniform point source of one candela.
Luminous Flux: The time rate of luminous energy flow, measured by its capacity to evoke a visual sensation. It is
expressed in lumens.
Luminous Intensity: The luminous flux radiated by a point source. It is expressed in candela.
LUX: The international unit of illumination. One LUX equals one lumen per square meter.
MTBCF: Mean Time Between Critical Failure
Photometer: Any optical device which uses a comparison technique to measure luminous intensity, luminance,
or illumination. An equality-of-brightness photometer is based on simultaneous comparison of adjoining visual
areas; a flicker photometer compares successive stimuli in the same visual area.
Resolution: The number of addressable, controllable display or picture elements, or the number of hypothetical
coordinate locations which can be used to position graphic elements on a display surface.
Shades of Gray: A division of the gray scale from black to white into a series of discrete luminance shades with a
square-root-of-2 difference between successive shades.
SVGA- Super Video Graphics Adapter
Sync: A contraction of synchronous or synchronization.
VESA: Video Electronics Standards Association
VGA: Video Graphics Adapter
White: The common usage word for high-luminance achromatic colors.
XGA: Extended Graphics Adapter
