picture tube

Old television display

A picture tube is the cathode ray tube in a television set—the large glass vacuum tube that displays images by firing electron beams at a phosphorescent screen.

The term was common when televisions were bulky furniture pieces built around these heavy components.

Flat-screen technology has made picture tubes largely obsolete.
