Color TVs typically use three electron guns, one for each primary color: red, green, and blue. These guns emit streams of electrons that are directed onto a phosphorescent screen coated with these colors. By varying the intensity of the electron beams, the TV can create a full range of colors through additive color mixing.

How many electrons are in oxygen's outer level?
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
What is thermonic emission?
Thermionic emission is the process by which electrons are emitted from a heated metal or semiconductor surface. When the material is heated to a sufficiently high temperature, some of the electrons gain enough energy to overcome the work function of the material and escape into the surrounding space. This phenomenon is used in vacuum tubes and electron guns.
