Triad (computers)

For other meanings see Triad (disambiguation).

In computer terms, a triad is a group of three phosphor dots on the inside of a computer monitor (CRT-type) coloured red, green, and blue. Triads are separated by dot pitch. By directing differing amounts of electrons onto the three phosphor dots, the triad will display a colour by combining the red, green and blue elements.

On LCDs, colours are similarly composed of these three colours.
