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.
