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
