Glossary

Electron

An electron is a small sub-atomic particle that carries a negative charge, which are used in cathode ray display tubes to carry a small charge to a phosphor dot on a Cathode Ray Tube screen, exciting the phosphor dot and producing a brief spark of light.

Dot-Pitch

This refers to the diagonal distance between coloured dots on-screen and is measured in millimetres.

Pixel

A pixel is the basic component that is used to make up an image on a computer screen, and can be only one colour. By arranging thousands of different coloured pixels into a grid, human-readable images can be built on a monitor screen.

Phosphor

A phosphor is a sub-division of a pixel. When clustered into groups of three, they then create a pixel, which then creates an image on a CRT monitor screen. When excited by directed electrons, phosphor dots produce a small amount of visible light in the same colour as the phosphor dot.

DVI

Stands for Digital Visual Interface. This is an optional input on LCD flat panel monitors which allows you to gain a higher resolution, using a digital lead to connect your computer to the monitor

VGA

Stands for Video Graphics Array. This is a type of basic setting found on most motherboards, which allows you to run a maximum resolution of 640 x 480 on your monitor. Preceded by CGA and superseded by SVGA.
