Television screens used to use a technology called, cathode ray tubes (CRT). An electron gun emitted electrons inside a glass tube onto phosphor atoms at the end of the glass tube, causing the phosphor atoms to light up. The electron gun scanned the screen many times per second, producing an image. . Briefing for SEAB. 20 June 2014. Patricia M. Dehmer. Acting Director, Office of Science. U.S. . Department of .
