Helsse rapped at a door displaying a pale blue phosphor.

That is, the blue electron gun will strike blue phosphors, but will find a wire blocks the path to red and green phosphors.

The red, green, and blue phosphors for each pixel are generally arranged in a triangular shape (sometimes called a "triad").

One arrangement is to use one tube and three phosphor (red, green, blue) coatings.

A team of materials scientists finally produced a second, vibrant blue phosphor early in 2001.

Instead, the screen is coated with red, green and blue phosphors arranged in dots or stripes.

Behind each space are a series of red, blue and green phosphors (substances that give off light when struck by light).

In standard television, the signal activates an electron gun that fires electrons at red, green and blue phosphors, which glow to form an image.

It is used as a blue phosphor in color CRTs.

In addition to the gas, each cell is coated with a red, blue or green phosphor.
