In older TV sets, the picture tube contained a colored matrix of red, blue and green (primary colors) coating that was applied to the inside of the front of the picture tube. The neck of the tube contained an "electron gun" that emitted a stream of electrons that impacted the coated tube surface. When an electron impinged the surface, it gave off energy, visible as light. The electron beam was controlled by a "deflection" circuit that caused the beam to sweep across the tube horizontally, and also move from top to bottom vertically. The end result is the creation of visible light on the screen. There is more to it, but this gives you an idea. Current TV's use projection circuit, etc., but the basic principle is the same.
