- 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 LCD displays, colours are similarly composed of these three colours.
