Most simplistically, it works on radio waves, invisible wave lengths that can be picked up by receivers and translated into electronic signals that control displays on a "picture tube".
Most recently, digital signals have replaced analog waves, and of course many people are now receiving the electronic TV digital signals via cable, rather than by air-waves.
TV's, unlike just a radio, need to have a video tube, and an electronic tuner to put "color" pixels onto a screen of some sorts (plasma, or LCD's are more common today, than old picture tubes)

What is the scientific principle behind a laptop?
Electrodynamic theory.
What is the scientific principle of television?
The scientific principle of television involves converting electrical signals into images and sound using cathode ray tubes or liquid crystal displays. This process relies on the principles of electromagnetism, electronics, and optics to transmit and display visual and audio information on a screen for viewers to see and hear.
