New television technologies
What we know today as the television set contains a cathode ray tube (CRT), a large device used to throw electrons at the television screen to create the images we see. The size of this tube is why CRT television sets need to be rectangular boxes.
In recent years other technologies have improved to the point where they can also be used to deliver television, without the need for a large box behind the screen.
Some of these technologies includes plasma and LCD screens, and front projection home cinemas.
Plasma screens |
The first plasma television came onto the market in 1997. While still relatively expensive, it uses more electricity and has a lower image quality than other kinds of television. Plasma has become a popular choice for people who want a large screen viewing experience in their home.

LCD screens |
While Liquid Crystal Display (LCD) screens have been available for many years in common household appliances, they were too expensive for use as computer monitors or televisions. This changed in the late 1980s and now LCD, or flat-screen, monitors and televisions are becoming more common.

Front projection home cinemas |
Front projection home cinemas create a cinema-like experience by projecting large television images on a screen or wall. While available since the early 1970s, modern technological advances, digital quality television and larger homes have made these projectors more attractive in recent years.
