Televisions CRT

Televisions CRT

A cathode-ray tube is a vacuum tube containing one or more electron guns, the beams of which are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms, pictures, radar targets, or other phenomena. A CRT on a television set is commonly called a picture tube. CRT material and process technologies are common to the vacuum tube industry as a whole, which continues to serve many applications across a wide variety of industries.

Still, CRTs have their perks. Most have a better contrast ratio and higher refresh rates than modern LCD monitors, so content looks richer and deeper. There's a sub-culture of first-person shooter fans who swear FPS games always look best on a high-end CRT monitor. Respondents also provided the number of CRT units in their homes from none up to “4 or more.” Analysis of the results suggests there are approximately 77 million CRT TVs still in U.S. households and approximately 30 million CRT monitors.
