Gamma

Screen luminance as a function of video voltage approximately follows a mathematical power

function of the input video signal, the exponent of which is called gamma.

Grayscale

An achromatic scale ranging from black through a series of successively lighter grays to white.

Such a series may be made up of steps, which appear to be equally distant from one another. If the

Analog/ Digital converter is 8 bit, then the monitor can display at most 2

= 256 levels. For a color

monitor, R.G.B. each color hads 256 levels. Thus, total color can display is 256x256x256= 16.7

million.

Hue

The main attribute of a color that distinguishes it from other colors. For example, a color may have a

green, yellow, or purple hue. Color defined as having hue are know as chromatic colors. White,

black, and grays possess no hue.

IPS (In Plane Switching)

A technique of improving the viewing angle of an LCD where the liquid crystal molecules are

switched in the plane of the LCD layer rather than vertical to it.
