![]() One tube goes out and you have to track it down and replace it, otherwise everything won’t work right. It’s like wiring your house for Christmas. Imagine a computer made up of thousands of tubes. This was before the transistor came on the scene. It was the ENIAC computer, built around the late 1940s I believe, and had stacks and stacks of cathode ray tubes to do its processing. The first computer ever invented was made entirely of cathode ray tubes. June 2, - Here’s an interesting bit of trivia. Still, the CRT maintains its popularity in television systems, as evidenced by the fact that the television is frequently referred to as “the tube.”Ĭathode ray tubes play an important role in oscilloscopes. Organic light-emitting diode (OLED) displays are also used to produce images. However, there have been many new developments in display technology, such as plasma screens, liquid crystal display televisions (LCD TVs), and digital light processing (DLP) devices. The cathode ray tube still plays a major part in television sets and many other electronic devices. It was also more durable than some of the previously introduced CRTs. ![]() Du Mont introduced the first tube that was considered practical for use in a television set. Called the kinescope, it was designed for used with some of the earliest televisions. In 1929, Vladimir Kosma Zworykin created another type of CRT. Braun’s cathode ray oscilloscope is considered the predecessor of modern tubes used in television sets. The screen of this tube would display a light when a beam of electrons touched it. This new technology was called a cathode ray oscilloscope. His invention consisted of a tube with a fluorescent screen. A German physicist named Karl Ferdinand Braun is credited with inventing the cathode ray tube in 1897.
