How did the old tube televisions work?



  1. 0 Votes

    A tube television takes its name from its main mechanism, a Cathode Ray Tube.  It is basically a vaccum tube through which a stream of electrons is fired at a phosphor-coated screen.  When the electrons hit the phosphor screen, the colors light up.  The trajectory of the stream of electrons can be manipulated using coils of wires, which create magnetic fields when current is run through them.
