Triad (monitors)

In CRT or computer terminology, a triad is a group of three phosphor dots coloured red, green, and blue on the inside of the CRT display of a computer monitor or television set. By directing differing intensities of electron beams onto the three phosphor dots, the triad will display a colour by combining the red, green and blue elements. Each triad forms one pixel of the displayed image.

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