The shadow mask is one of two major technologies used to manufacture cathode ray tube (CRT) televisions and computer displays that produce color images. All early color televisions and the majority of CRT Computer Monitors used shadow mask technology. A shadow mask is a metal plate punched with tiny holes that separate the colored phosphors in the layer behind the front glass of the screen. Three electron guns at the back of the screen sweep across the mask, with the beams only reaching the screen when they pass over the holes. As the guns are physically separated at the back of the tube, their beams approach the mask from three slightly different angles, so after passing through the holes they hit slightly different locations on the screen.
The screen is patterned with dots of colored phosphor positioned so they can only be hit by the beam from only one of the guns passing through only one of the holes. For instance, a particular spot on the screen can only be hit by the beam from the "blue gun" passing through a particular hole in the mask. This arrangement allows the colored guns to address individual dots on the screen, even though their beams are much too large and too poorly aimed to do so without the mask in place.
The red, green, and blue phosphors for each pixel are generally arranged in a triangular shape (sometimes called a "triad"). For television use, modern displays (starting in the late 1960s) use rectangular slots instead of circular holes, improving brightness
